Postoperative Pain After Cesarean Birth Affects Breastfeeding and Infant Care

Continuous ropivacaine wound infiltration versus epidural morphine after unplanned caesarean delivery: A noninferiority randomised controlled study

BACKGROUND

Treatment programs designed to enhance recovery after caesarean delivery include multimodal analgesia to ensure optimal analgesia while reducing exposure to systemic opioids. Evidence for the effectiveness of continuous wound infiltration with local anaesthetic after unplanned caesarean delivery is needed.

OBJECTIVE

To determine whether continuous ropivacaine wound infiltration has noninferior analgesic properties compared to epidural morphine, while reducing side effects related to opioids.

DESIGN

Triple-blinded, noninferiority, randomised controlled trial.

SETTING

One university hospital, between February 2015 and August 2021.

PATIENTS

Eighty-one women undergoing unplanned lower segment caesarean section under epidural anaesthesia.

INTERVENTION

At the end of the procedure, randomly assigned patients received either an epidural bolus of 0.9% saline with 48 h continuous ropivacaine wound infusion (ropivacaine group) or an epidural bolus of morphine with 48 h 0.9% saline wound infusion (morphine group).

MAIN OUTCOME MEASURES

Pain during mobilisation at 24 h postsurgery was assessed using the visual analogue pain scale (VAS 0 to 10) with no indication of the allocated group.

RESULTS

Pain scores were 4.4 (95% CI, 3.6 to 5.1) in the ropivacaine group versus 3.1 (95% CI, 2.4 to 3.9) in the morphine group. The mean VAS pain difference between the two groups was 1.2 (95% CI, 0.2 to 2.3), which exceeded the prespecified noninferiority margin of 1. The differences between the two groups at rest and during mobilisation at 6 and 24 h were statistically significant. The ropivacaine group received rescue morphine more frequently, and were less satisfied despite fewer morphine-related side effects. Continuous wound infiltration was not technically feasible in 18% of the patients.

CONCLUSIONS

We failed to show that continuous ropivacaine wound infiltration was noninferior to epidural morphine in providing analgesia after unplanned caesarean delivery. Because of a significant rate of technical failures, continuous wound infiltration should only be considered when neuraxial morphine is contraindicated.

Predicting Postcesarean Pain: A Prospective Cohort Study Using a 3-Question Questionnaire, Local Anesthesia Infiltration, and Observer Rating

Purpose: Acute postoperative pain is a typical complaint following cesarean delivery (CD). The current standard for postcesarean pain management is the use of a multimodal analgesia regimen which is beneficial for many but may be inadequate for some patients. This study aimed to determine if combining patients' response to a pain rating questionnaire, their pain score during local anesthetic infiltration (LAI) preceding spinal anesthesia for CD, and an anesthesiologist's prediction of postcesarean pain severity can predict the intensity of postcesarean pain. Methods: This was a prospective study of ninety women undergoing scheduled CD under spinal anesthesia. Patients completed a pain rating questionnaire preoperatively and rated pain on LAI before spinal injection, and an anesthesiologist predicted the severity of postcesarean pain. Postoperative pain scores were assessed at rest and with movement at 6, 24, and 48 h after surgery. Results: The patient's expected postoperative pain (β = 0.39, p=0.0011), perceived analgesic requirements (β = 0.34, p=0.0002), pain on LAI (β = 0.22, p=0.004), and anesthesiologist's predicted postoperative pain severity (β = 0.22, p=0.01) were associated with mean postoperative pain after CD. The multivariate model analysis found that the pain rating questionnaire and the an anesthesiologist's prediction of postcesarean pain severity contributed to postoperative pain modeling (R 2 = 0.27). Conclusion: Combining a preoperative pain rating questionnaire with an anesthesiologist's prediction of postcesarean pain severity accounted for 27% of the variance in mean postoperative pain with movement and may be a useful tool in predicting postcesarean pain. Implications: This study highlights the potential of a combined preoperative pain rating questionnaire and anesthesiologist's predictions to improve postcesarean pain management. By accounting for 27% of the variance in mean postcesarean pain with movement, this approach could enhance pain management outcomes for CD patients.

Can theory-driven implementation interventions help clinician champions promote opioid stewardship after childbirth? Protocol for a pragmatic implementation study

Background

Our objective is to determine the effect of a new national clinical practice guideline (CPG) for pain management after childbirth, as implemented with less vs. more intensive implementation support, on postpartum opioid prescribing.

Methods

A quasi-experimental analysis will measure the impact of post-childbirth pain management guidelines on opioid prescribing in a statewide hospital collaborative, overall and among key patient subgroups at risk for inequitable care and outcomes. We will also use a randomized, non-responder design and mixed-methods approaches to evaluate the effects of Replicating Effective Programs (REP), a theory-driven, scalable implementation intervention, and Enhanced REP (E-REP; i.e., REP augmented with facilitation, which is individualized consultation with site champions to overcome local barriers) on the uptake of the CPG. The study will include hospitals within the Obstetrics Initiative (OBI), a perinatal collaborative quality initiative funded by Blue Cross Blue Shield of Michigan that includes 68 member hospitals serving more than 120,000 postpartum people, over approximately 15 months. Hospitals not initially responding to REP-defined by performance <15th percentile of all OBI hospitals for (a) inpatient order for opioid-sparing postpartum pain management (e.g., scheduled acetaminophen and non-steroidal anti-inflammatory drugs when not contraindicated), or (b) amount of opioid prescribed at discharge-will be allocated via block randomization to continue REP or to E-REP. Using interrupted time series analyses, the primary analysis will evaluate the rate of postpartum opioid-sparing prescribing metrics at the time of discharge (primary outcome) and opioid prescription refills and high-risk prescribing (secondary outcomes) before and after CPG implementation with REP. We will evaluate inequities in outcomes by patient, procedure, prescriber, and hospital factors. Exploratory analyses will examine temporal trends in patient-reported outcomes and the effects of continued REP vs. E-REP among slower-responder sites. We will evaluate implementation outcomes (e.g., acceptability, feasibility, costs, needed REP and E-REP adaptations) using clinician and patient surveys and qualitative methods (ClinicalTrials.gov identifier: NCT06285123).

Discussion

Findings will inform refinements to the REP and E-REP interventions and add to the literature on the effectiveness of facilitation to promote uptake of evidence-based clinical practices in maternity care.

The effect of an abdominal binder on pain, bleeding and breastfeeding success after cesarean delivery: A randomized controlled trial

This randomized controlled intervention study aims to determine the effect of an abdominal binder on pain, bleeding, and breastfeeding success after cesarean delivery. The study was conducted with women who underwent cesarean section and were followed-up for the first 48 hours at the obstetrics clinic of a state hospital in Türkiye between September 2020-March 2021. The study was completed with a total of 128 women who met the inclusion criteria (Intervention (IG):64, Control (CG):64). Data were collected using a "Socio-demographic Form" and "Postpartum Follow-up Form." Statistical significance was defined as p < .05. The IG showed significantly lower pain scores in both the abdominal area (uterine involution) and cesarean incision compared to the CG (p < .001), (respectively, IG:0.19 ± 0.58 vs. CG:1.33 ± 1.16; IG:0.23 ± 0.61 vs. CG:0.75 ± 1.26). The amount of puerperal bleeding was significantly lower in the IG (p < .001) (IG:327.65 ± 112.61 mL vs. CG:402.61 ± 157.45 mL), and their hemoglobin and hematocrit values were significantly higher (p < .05) (Hemoglobin, IG:11.00 ± 0.78 g/dL vs. CG:10.62 ± 0.90 g/dL; Hematocrit, IG:34.54 ± 1.79 percent vs. CG:33.51 ± 2.56 percent). The breastfeeding success scores were significantly higher in the IG (p < .001) (IG:9.97 ± 0.17 vs. CG:9.81 ± 0.43). These data demonstrate that the abdominal binder is beneficial and applicable for reducing pain, bleeding, and for improving breastfeeding success in the first 48 hours after cesarean delivery.

Development of an implementation intervention to promote adoption of the COMFORT clinical practice guideline for peripartum pain management: a qualitative study

BACKGROUND

Pain management after childbirth is widely variable, increasing risk of untreated pain, opioid harms, and inequitable experiences of care. The Creating Optimal Pain Management FOR Tailoring Care (COMFORT) clinical practice guideline (CPG) seeks to promote evidence-based, equitable acute peripartum pain management in the United States. We aimed to identify contextual conditions (i.e., barriers and facilitators) and discrete implementation strategies (i.e., theory-based actions taken to routinize a clinical practice) likely to influence COMFORT CPG uptake and specify corresponding multi-component implementation interventions at the perinatal quality collaborative- and unit-level.

METHODS

We conducted a qualitative study involving virtual individual interviews and focus groups. Interviews included individuals undergoing childbirth from 2018-2023, (recruited through two online registries), and actively practicing maternity clinicians and surgeons, (recruited via snowball sampling with the eDelphi panel creating the COMFORT CPG), caring for pregnant people in the United States. Focus groups included physicians, midwives, nurses, and unit-based quality improvement (QI) staff working at Michigan hospitals within the Obstetrics Initiative, a statewide perinatal quality collaborative funded by Blue Cross Blue Shield of Michigan and Blue Care Network. The Consolidated Framework for Implementation Research, Expert Recommendations for Implementing Change taxonomy, and Replicating Effective Programs framework informed data collection and analysis. Qualitative content analysis characterized influential contextual conditions, which were linked to implementation strategies and tools using principles of implementation mapping. We then specified multi-component implementation interventions for use by quality collaboratives and unit-based teams.

RESULTS

From May-September 2023, we completed 57 semi-structured individual interviews (31 patients, 26 clinicians) and six focus groups (44 QI champions). Participants identified 10 key conditions influential for COMFORT CPG adoption. Findings enabled identification of five collaborative-level implementation strategies, 27 unit-level implementation strategies, and 12 associated tools to promote COMFORT CPG adoption including the specification of each strategy's hypothesized mechanism of action and each tool's goal and potential uses.

CONCLUSIONS

This work identifies contextual conditions and implementation strategies and tools at the perinatal quality collaborative and unit levels to promote COMFORT CPG adoption on maternity units. These findings may foster more rapid CPG implementation and thereby promote more equitable and evidence-based perinatal pain management care.

Prevalence and Associated Factors of Postoperative Acute Pain for Mothers Who Gave Birth With Cesarean Section: A Systematic Review and Meta-Analysis

BACKGROUND

Cesarean section frequently is associated with different undesirable postoperative outcomes. Acute postoperative pain is one of the most frequently experienced adverse outcomes that occurs as the result of actual tissue damage. Previous studies have shown inconsistent results regarding the prevalence and predictors of acute postoperative pain. Therefore, this study aimed to assess the pooled prevalence and associated factors of postoperative pain after cesarean section.

METHODS

This is a systematic review and meta-analysis study that was performed on the basis of studies published within the last 10 years on the prevalence and associated factors of postoperative pain after cesarean section. After PubMed, Google Scholar, HINAR, Scopus, Web of Sciences, Cochrane, EMBASE, and gray literature extensive search for primary studies, their quality was assessed and data was extracted. STATAMP, version 17.0, was used for all possible analyses of the study.

RESULTS

Twenty-eight studies were included in this systematic review and meta-analysis. The pooled prevalence of postoperative pain was 58% (95% confidence interval [CI] 48%, 67%) with heterogeneity (I2 99.33%). Incision length >10 centimeters (odds ratio [OR] 2.34 [95% CI 1.71, 2.97]); spinal anesthesia without adjuvant (OR 3.45 [95% CI 1.56, 5.33]); general type of anesthesia (OR 3.54 [95% CI 2.61, 4.48]); presence of preoperative anxiety (OR-1.73, 95% CI 1.12-2.35); and no peripheral nerve block (OR 3.23 [95% CI, 2.27-4.18]) were associated with the prevalence of postoperative pain significantly.

CONCLUSIONS

The pooled prevalence of acute postoperative pain after cesarean section was high (58%), which needs more strategies for pain management. Incision length >10 centimeters, spinal anesthesia without adjuvants, general type of anesthesia, preoperative anxiety, and no peripheral nerve block were significantly associated with this prevalence.

Predicting the Severity of Acute Pain after Cesarean Delivery: A Narrative Review

PURPOSE OF THE REVIEW

Cesarean delivery is one of the most common surgical procedures performed worldwide. Approximately 28-78% of the patients have reported experiencing severe pain after Cesarean delivery, which is associated with adverse outcomes. Current analgesic management strategies employ a one-size-fits-all approach, which may not be suitable for all post-Cesarean patients. Our ongoing research and the purpose of this review are focusing on preoperative risk assessment to identify patients at risk of severe pain or needing higher doses of opioid or other analgesics.

RECENT FINDINGS

Recent clinical investigations have found that by utilizing the demographic and psychological evaluations, screening tests, quantitative sensory testing, and assessment of response to local anesthetic infiltration, clinicians were potentially able to stratify the risks for severe post-cesarean pain. Several modalities demonstrated significant correlations with pain outcomes, although most of these correlations were weak to modest. Since consensus statement regarding predicting post-CD pain control are still lacking, these correlations can be clinically helpful. It is possible to identify patients at high risk of developing severe acute pain after cesarean section by preoperative demographic data, screening questionnaires, or other tools. Further studies are needed to identify additional variables or screening tools for more accurate prediction and investigate whether personalized analgesic regimens can lead to improved analgesic outcomes.

Comparative Evaluation of Two Doses of IV Dexamethasone for Postoperative Analgesia in Patients Undergoing Lower Segment Cesarean Section Under Spinal Anesthesia: A Randomized Controlled Trial

Introduction Effective postoperative analgesia following lower segment cesarean section (LSCS) is crucial for promoting surgical recovery and fostering maternal-neonatal bonding. This study aimed to compare the efficacy of two IV dexamethasone doses (8 mg and 4 mg) in managing postoperative pain in LSCS patients. The objective was to assess whether the 4 mg dose provides comparable pain relief to the 8 mg dose, with the goal of identifying the optimal dosage for effective pain management with minimal side effects. Methods This prospective, randomized, interventional comparative study was conducted on 70 parturients undergoing LSCS under spinal anesthesia (SA). The participants were randomly assigned into two groups of 35 each. Group A received 8 mg of IV dexamethasone, while Group B received 4 mg intravenously after the delivery of the baby. The Visual Analogue Scale (VAS) score, time to first rescue analgesia, total rescue analgesic consumption within 24 hours, duration of sensory and motor blockade, incidence of postoperative nausea and vomiting (PONV), and blood sugar levels were measured every six hours up to 24 hours post-surgery for both groups. Results The results revealed a significantly lower VAS score in Group A compared to Group B (p < 0.05). However, the incidence of PONV and the duration of sensory and motor blockade were similar between the two groups (p > 0.05). Blood sugar levels were higher in Group A at all time points (p < 0.05). Conclusions The 4 mg dose of dexamethasone appears to be a better alternative for postoperative analgesia compared to the 8 mg dose in patients undergoing LSCS under SA. It was associated with a lower mean VAS score, a reduced incidence of PONV, and a smaller increase in blood sugar levels.

Comparison of erector spinae plane and transversus abdominis plane block for postoperative analgesia after caesarean delivery under spinal anaesthesia: A randomised controlled trial

BACKGROUND

Truncal blocks contribute to multimodal analgesia that enhances early recovery after caesarean delivery. The transversus abdominis plane (TAP) block is an established technique that offers somatic abdominal wall analgesia. The erector spinae plane (ESP) block is a fascial plane technique that may offer additional visceral analgesic effects. This study hypothesized that ESP block would offer superior analgesic efficacy to TAP block in women undergoing caesarean delivery under spinal anaesthesia.

METHODS

Sixty-six ASA physical status grade 1-3 (≥18 years) patients undergoing elective caesarean delivery under spinal anaesthesia were randomly allocated to receive either bilateral ultrasound-guided TAP (N = 33) or ESP blocks at the T9 vertebral level (N = 35). The primary outcome measure was 24-hour cumulative morphine consumption. The secondary outcomes included time to first analgesic request, duration of block placement, numeric rating scale (NRS) pain scores at rest and movement, effect of pain on activities of daily living (ADLs) and care for the infant, patient analgesic satisfaction, frequency and severity of opioid-related side effects.

RESULTS

There was no statistically significant difference in mean (95% CI) 24-hour cumulative morphine consumption between groups: 32.0 (27.0 to 37.0) mg with TAP versus 27.0 (19.9 to 34.0) mg with ESP (p = 0.16). The mean (SD) duration of block placement was longer for ESP than for TAP blocks (10.7 (2.2) minutes versus 9.0 (2.5) minutes; p = 0.004). There were no significant differences in the other secondary outcomes.

CONCLUSION

This study found similar postoperative opioid use and analgesic efficacy between ESP and TAP block after caesarean delivery performed under spinal anaesthesia.

The Effects of Transcutaneous Electrical Nerve Stimulation Applied in the Early Postpartum Period After Cesarean Birth on Healing, Pain, and Comfort

INTRODUCTION

This study was conducted to determine the effects of transcutaneous electrical nerve stimulation (TENS) applied in the early postpartum period after cesarean birth on incision site healing, postoperative recovery, pain, and comfort.

METHODS

This randomized, single-blind, placebo-controlled study was conducted with 138 women (TENS group n = 46, placebo group n = 46, control group n = 46) who gave birth by cesarean between January and September 2023. TENS was applied twice at a frequency of 100 Hz with a pulse width of 100 microseconds, at 10 to 12 and 14 to 16 hours after birth, for 30 minutes each. Outcomes were measured with the Postoperative Recovery Index; Redness, Edema, Ecchymosis, Discharge, and Approximation Scale; Visual Analogue Scale; and Postpartum Comfort Questionnaire. Outcomes between groups were compared postintervention, correcting for baseline using analysis of covariance. The study was registered at www.

CLINICALTRIALS

gov (NCT05991921).

RESULTS

Mean scores for postoperative recovery were significantly lower (improved) in the TENS group (113.58) compared with the placebo and control groups (134.67, 136.61; P < .001). The postoperative recovery subscales (psychological symptoms, physical activities, appetite symptoms, bowel symptoms, general symptoms) were also significantly decreased in the TENS group compared with the placebo and control groups. Similarly, mean scores for postpartum comfort, and the corresponding physical comfort, psychospiritual comfort, and sociocultural comfort subscales, were significantly improved in the TENS group (110.26) compared with the placebo and control group (83.80, 81.19; P < .05).

DISCUSSION

TENS application can be preferred as an alternative method to increase pain control, recovery, and patient comfort after cesarean birth.

Exploring the Analgesic Efficacy and mechanisms of low-dose esketamine in pregnant women undergoing cesarean section: A randomized controlled trial

Background

Postoperative pain is a prevalent concern following a cesarean section. This study aimed to investigate the effect and mechanism of low-dose (0.1 mg/kg) esketamine on postoperative pain management in pregnant women undergoing cesarean sections, specifically in cases where both patient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia (PCEA) were employed.

Methods

Pregnant women intending to undergo elective cesarean section were divided into four subgroups based on the intravenous administration of esketamine and the specific analgesia methods employed: E1 (0.1 mg/kg esketamine + PCEA), E2 (0.1 mg/kg esketamine + PCIA), C1 (saline + PCEA), and C2 (saline + PCIA). The primary outcome was the maximum pain score within 24 h postoperatively. Secondary outcomes included the pressure pain threshold and tolerance at 30 min and 24 h postoperatively, along with the inflammation and adverse event index scores.

Results

A total of 118 pregnant women were assigned to the four groups: E1 (n = 29), E2 (n = 29), C1 (n = 30), and C2 (n = 30). Compared with those in the control groups (C1 + C2), the maximum postoperative pain scores within 24 h in the esketamine groups (E1 + E2) were significantly lower (4 [2-5] vs. 4 [4-6], P = 0.002), and the E1 group exhibited superior analgesic effects compared with other groups. No significant differences were observed in postoperative hyperalgesia or inflammation across the four groups. Notably, esketamine combined with PCIA increased the incidence of postoperative nausea and vomiting (7 [25 %] vs. 0 [0 %]; P = 0.005).

Conclusion

The administration of low-dose (0.1 mg/kg) esketamine effectively alleviates pain following cesarean section, and the analgesic effect is notably enhanced in combination with PCEA. Importantly, these effects do not appear to be mediated through anti-inflammatory mechanisms or the inhibition of hyperalgesia.

Transversus Abdominis Plane Block versus Epidural Anesthesia for Pain Management Post-Caesarean Delivery: A Pilot Study

Background

Effective post-operative analgesia profoundly influences patient recovery and outcomes after caesarean delivery. The Transversus Abdominis Plane (TAP) block represents a potential alternative, potentially offering greater effectiveness than epidural analgesia while causing fewer adverse effects.

Objective

To assess if the abdominal transverse block provides superior postoperative pain relief in patients undergoing caesarean delivery compared to epidural analgesia.

Methods

Participants were divided into parallel groups: an experimental group receiving TAP block (n=25) and a control group receiving epidural analgesia (n=24). All patients received a 10 mg dose of hyoscine at the end of the surgery. Experimental Group received a total of 20 mL of 0.2% ropivacaine. In Epidural group received 0.2% ropivacaine at 4 mL/h for 24 hours. All participants were administered combined with neuroaxial block anesthesia. The patients selected for epidural analgesia received the mentioned dose, while the other group block had the epidural catheter removed after the cesarean section. The primary outcome was post-caesarean pain, evaluated using the Visual Analog Scale (VAS) at four intervals (0, 6, 12, and 24 hours). Also, surgical bleeding and residual motor were evaluated. VAS pain scores between the groups were compared using the Friedman test and Generalized Linear Model (GLM) for non-normally distributed data. The effect size was estimated with Eta Square ([Formula: see text]), considering values ≥0.38 as indicative of large effects. A two-tailed p-value < 0.05 was deemed statistically significant.

Results

Statistically significant differences in pain scores were noted at 0 and 6 hours post-surgery (p<0.01). The TAP block group reported lower pain scores at 0 hours (mean=0.04) and 6 hours (mean=1.16) compared to the epidural group, reflecting a substantial effect size.

Conclusion

The TAP block proves advantageous in mitigating postoperative pain for women post-caesarean delivery, particularly in the initial 6 postpartum hours. This relief promotes early mother-infant bonding and facilitates breastfeeding.

Comparison of different nonsteroidal anti-inflammatory drugs for cesarean section: a systematic review and network meta-analysis

BACKGROUND

Cesarean section is associated with moderate to severe pain and nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly employed. The optimal NSAID, however, has not been elucidated. In this network meta-analysis and systematic review, we compared the influence of control and individual NSAIDs on the indices of analgesia, side effects, and quality of recovery.

METHODS

CDSR, CINAHL, CRCT, Embase, LILACS, PubMed, and Web of Science were searched for randomized controlled trials comparing a specific NSAID to either control or another NSAID in elective or emergency cesarean section under general or neuraxial anesthesia. Network plots and league tables were constructed, and the quality of evidence was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE) analysis.

RESULTS

We included 47 trials. Cumulative intravenous morphine equivalent consumption at 24 h, the primary outcome, was examined in 1,228 patients and 18 trials, and control was found to be inferior to diclofenac, indomethacin, ketorolac, and tenoxicam (very low quality evidence owing to serious limitations, imprecision, and publication bias). Indomethacin was superior to celecoxib for pain score at rest at 8-12 h and celecoxib + parecoxib, diclofenac, and ketorolac for pain score on movement at 48 h. In regard to the need for and time to rescue analgesia COX-2 inhibitors such as celecoxib were inferior to other NSAIDs.

CONCLUSIONS

Our review suggests the presence of minimal differences among the NSAIDs studied. Nonselective NSAIDs may be more effective than selective NSAIDs, and some NSAIDs such as indomethacin might be preferable to other NSAIDs.

Inflammatory changes in the plasma and cerebrospinal fluid of patients with persistent pain and postpartum depression after elective Cesarean delivery: an exploratory prospective cohort study

PURPOSE

Severe acute pain after Cesarean delivery increases the risk of developing persistent pain (~20% incidence) and postpartum depression (PPD) (~15% incidence). Both conditions contribute to maternal morbidity and mortality, yet early risk stratification remains challenging. Neuroinflammation has emerged as a key mechanism of persistent pain and depression in nonobstetric populations. Nevertheless, most studies focus on plasma cytokines, and the relationship between plasma and cerebrospinal fluid (CSF) cytokine levels is unclear. Our primary aim was to compare inflammatory marker levels between patients who developed the composite outcome of persistent pain and/or PPD vs those who did not.

METHODS

We recruited term patients with singleton pregnancies undergoing elective Cesarean delivery under neuraxial anesthesia into an exploratory prospective cohort study. We collected baseline demographic, obstetric, and Edinburgh Postnatal Depression Scale information, and performed quantitative sensory tests. Plasma was collected preoperatively and 48 hr postoperatively. In the operating room, 10 mL of CSF was collected, followed by a standardized anesthetic. Intra- and postoperative management were according to standard practice. We obtained Edinburgh Postnatal Depression Scale and pain scores at six weeks and three months after delivery. The primary outcome was persistent pain and/or PPD at three months. We analyzed the difference in inflammatory marker levels between the groups (primary aim) using two-sided Mann-Whitney tests.

RESULTS

Eighty participants were enrolled, and 63 patients completed the study; 23 (37%) experienced the primary outcome at three months. Preoperative plasma transforming growth factor beta 1 (TGF-β1) concentration was higher in patients who developed the primary outcome compared with those who did not (median [interquartile range (IQR)], 2,879 [2,241-5,494] vs 2,292 [1,676-2,960] pg·mL-1; P = 0.04), while CSF IL-1β concentration was higher in patients who developed the primary outcome than in those who did not (median [IQR], 0.36 [0.29-0.39] vs 0.30 [0.25-0.35] pg·mL-1; P = 0.03).

CONCLUSIONS

We observed differential levels of plasma and CSF inflammatory biomarkers in patients who developed persistent pain and PPD compared with those who did not. We showed the feasibility of collecting plasma and CSF samples at Cesarean delivery, which may prove useful for future risk-stratification.

Risk Factors for Severe Pain and Impairment of Daily Life Activities after Cesarean Section-A Prospective Multi-Center Study of 11,932 Patients

Cesarean section (CS) is the most widely performed and one of the most painful surgeries. This study investigated postoperative pain after CS using patient-related outcomes (PROs) to identify risk factors for severe pain. The secondary outcome was to evaluate the influence of surgery indication (primary CS (PCS) vs. urgent CS (UCS)). This multi-center, prospective cohort study included data submitted to the pain registry "quality improvement in postoperative pain treatment" (QUIPS) between 2010 and 2020. In total, 11,932 patients were evaluated. Median of maximal pain was 7.0 (numeric rating scale (NRS) 0 to 10); 53.9% suffered from severe pain (NRS ≥ 7), this being related to impairment of mood, ambulation, deep breathing and sleep, as well as more vertigo, nausea and tiredness (p < 0.001). Distraction, relaxation, mobilization, having conversations, patient-controlled analgesia (PCA) and pain monitoring were shown to be protective for severe pain (p < 0.001). Maximal pain in PCS and UCS was similar, but UCS obtained more analgesics (p < 0.001), and experienced more impairment of ambulation (p < 0.001) and deep breathing (p < 0.05). Severe pain has a major effect on daily-life activities and recovery after CS, and depends on modifiable factors. More effort is needed to improve the quality of care after CS.

Enhanced recovery protocol after cesarean delivery: impact on opioid use and pain perception

BACKGROUND

Opioids are routinely prescribed to patients postoperatively after cesarean delivery. With rates of cesarean deliveries increasing globally and the opioid epidemic continuing to have deleterious effects, finding methods to achieve effective pain control without opioids is of increasing importance. The ERAS (Enhanced Recovery After Surgery) protocol applied following cesarean delivery engages multimodal perioperative management techniques to encourage early recovery. In the obstetrical surgery setting, these interventions include increasing scheduled nonsteroidal anti-inflammatory drug administration and laxative use to improve postoperative gastrointestinal motility and pain scores. Postcesarean patients are also encouraged to use abdominal binders, incentive spirometry, and early movement as pain modulators.

OBJECTIVE

This quality improvement study aimed to measure whether the introduction of an ERAS protocol following cesarean delivery at a United States-based health network would improve outcomes such as the use of opioid medications for pain and pain control.

STUDY DESIGN

This single-center retrospective cohort study compared patients who gave birth via cesarean delivery before (n=1425) and after (n=3478) the implementation of the postsurgical recovery protocol. Outcomes of interest included total postoperative opioid medications used, discharge opioid prescription, average pain score, pain scores by postoperative day, and highest pain score. Patients with a history of opioid use disorder, those who underwent a cesarean hysterectomy, and those who experienced a major surgical complication at delivery were excluded. Data were collected from the electronic medical record.

RESULTS

Patients in the postimplementation period used significantly fewer opioid medications than those who gave birth before the protocol was introduced at the institution. The total median opioid use before implementation was 75 morphine milligram equivalents (interquartile range, 45-112.5) vs 30 (interquartile range, 15-52.5) after implementation (P<.001). The median discharge prescription was 225 (interquartile range, 150-225) before implementation vs 112.5 (interquartile range, 75-150) after implementation (P<.001). Pain scores were also significantly lower after implementation. The median highest pain score was 8 (interquartile range, 6-8) on a 10-point pain scale before implementation vs 7 (interquartile range, 6-8) after implementation (P<.001). The average pain score before implementation was 3.4 (interquartile range, 2.4-4.5) vs 2.9 (interquartile range, 1.9-3.9) after implementation (P<.001). Results of paired-sample analyses of 177 patients who gave birth by cesarean delivery in both time periods showed statistically significant outcomes similar to those of the larger cohort groups.

CONCLUSION

Implementation of multimodal pain regimens following cesarean delivery, such as the ERAS protocol, which incorporate both pharmacologic (nonsteroidal anti-inflammatory drugs, laxatives) and nonpharmacologic methods (abdominal binders, deep breathing, movement) can be effective for pain control and may decrease postoperative opioid prescribing needs, thus mitigating the potential for opioid misuse and dependence.

Prospective evaluation of cerebrospinal fluid levels of β-Endorphin as a predictor of opioid use after scheduled cesarean delivery

Background

Prior laboratory work indicates that lower endogenous opioid function is associated with greater analgesic and subjective responses to opioid analgesics. We evaluated whether lower preoperative cerebrospinal uid (CSF) levels of the analgesic endogenous opioid β-Endorphin (BE) were associated with increased opioid use after cesarean delivery (CD).

Methods

We enrolled 136 pregnant women without opioid use or chronic pain who were undergoing CD under regional anesthesia. Preoperatively, participants completed validated pain measures and biospecimens were collected to assess BE levels in plasma and CSF. Postoperatively, pain measures at 48 hours and 2 weeks postpartum were assessed. We evaluated the association between CSF BE levels and total opioid use (in morphine milligram equivalents; MMEs) using linear regression controlling for confounding factors (primary analysis). In secondary analyses, we examined: 1) associations between plasma BE levels and total opioid use, and 2) associations between CSF and plasma BE levels and secondary outcomes (inpatient versus outpatient opioid use, pain intensity).

Results

Participants completed surveys with 100% response rate. The majority were non-Hispanic white (65%), college educated (58%), had private insurance (71%), and had a prior cesarean delivery (69%). Psychiatric diagnoses (depression or anxiety) were common, both currently (22%) and in the past (26%).The median total opioid use across the inpatient and 2-week postpartum follow-up period was 89.1 milligram morphine equivalents (IQR 25-138). Preoperative cerebrospinal uid β-Endorphin levels were not associated with total opioid use (beta = -0.05, SE 0.45, p = 0.64). Similar findings were noted for plasma β-Endorphin levels. cerebrospinal uid β-Endorphin levels were only weakly correlated with plasma β-Endorphin levels (r = 0.30, p < .01). Preoperative cerebrospinal uid and plasma β-Endorphin levels were both positively associated with postpartum pain measures (cerebrospinal uid: at 48 hours, beta = 0.19, SE 0.16, p < 0.05; Plasma: at 48-hours, beta = 0.02, SE 0.03, p = 0.02, and at 2-weeks, beta = 0.27, SE 0.03, p < 0.01).

Conclusions

Lower preoperative cerebrospinal uid levels of β-Endorphin are not associated with increased opioid analgesic use after scheduled cesarean delivery. It is possible that unassessed variability in baseline opioid receptor sensitivity may have confounded ability to test associations between β-Endorphin levels and opioid use outcomes.

Neonatal outcomes when intravenous esketamine is added to the parturients transferred from labor analgesia to emergency cesarean section: a retrospective analysis report

OBJECTIVES

The use of intravenous analgesics during emergency cesarean section may lead to adverse neonatal outcomes. In our study, we investigated whether a single intravenous (i.v.) dose of 25 mg esketamine administered to parturients with inadequate analgesia during epidural anesthesia for cesarean section would affect the neonate.

DESIGN

We reviewed the records of parturients who were transferred from labor analgesia to epidural anesthesia for emergency cesarean section from January 2021 to April 2022. Parturients were grouped by whether they received esketamine infusions during the incision-delivery interval. Neonatal outcomes, including umbilical arterial-blood gas analysis (UABGA), Apgar score, and total days spent by the neonate in the hospital, were compared between the two groups. The secondary outcomes of this study included BP, heart rate (HR), SPO₂ and the incidence of adverse effects in parturients during operation.

SETTING

China.

RESULTS

After propensity score matching, 31 patients remained in each of the non-esketamine and esketamine groups. There were no significant differences in neonatal outcomes, including UABGA, Apgar score, and total days in the hospital, between the two groups. Additionally, our study showed a similar hemodynamic performance in parturients between the two groups during operation.

CONCLUSIONS

Intravenous esketamine (25 mg) is safe for neonates when it is given to parturients transferred from labor analgesia to emergency cesarean section.

Women's experiences of breastfeeding after a cesarean section: A meta-synthesis

AIM

The World Health Organization and United Nations Children's Fund recommend the early initiation of breastfeeding within the first hour postpartum for successful exclusive breastfeeding. However, cesarean section is a risk factor for unsuccessful early initiation of breastfeeding. Herein, we aim to explore women's experiences of breastfeeding after a cesarean section.

METHODS

We used the Joanna Briggs Institute framework in this meta-synthesis. We searched articles published from 1990 to 2022 on PubMed, CINAHL, Cochrane library, PsycInfo, and EMBASE to identify qualitative studies on women's experiences of breastfeeding after a cesarean section. We used the Critical Appraisal Skills Programme checklist for qualitative studies to assess the quality of the included studies.

RESULTS

Seven qualitative studies from five countries met the inclusion criteria, representing the views of 194 women who underwent cesarean sections. Six new categories were integrated into the women's experiences of breastfeeding after a cesarean section as follows: (i) Perceived values of breastfeeding, (ii) Emotional vulnerability in breastfeeding, (iii) Physical difficulties in breastfeeding, (iv) Inconvenient conditions in breastfeeding, (v) Inadequate resources for breastfeeding, and (vi) Support systems to enable breastfeeding.

CONCLUSIONS

We provide evidence showing that knowledge of the specific breastfeeding mechanism and provision of the most appropriate postsurgical care by healthcare providers just after a cesarean section can reduce the barriers to post-cesarean breastfeeding. Moreover, effective hospital policies and family support can result in the initiation of positive breastfeeding outcomes. Future studies that consider the cultural aspects of breastfeeding practice may generate additional insights into providing optimal postpartum care.

Impact of Postoperative Pain on Early Initiation of Breastfeeding and Ambulation After Cesarean Section: A Randomized Trial

Aim: To compare the effect of different analgesic regimens on the time to initiate breastfeeding (BF) and ambulation after cesarean section (CS). Methods: This prospective, double-blinded, placebo-controlled randomized study included 300 women (20-40 years of age) of the American Society of Anesthesiologists status 1 or 2 with singleton term pregnancies scheduled for CS under spinal anesthesia. Women were allocated to three groups of 100 each by computer-generated randomization. As an adjunct to 1,000 mg intravenous acetaminophen, Group 1 received 100 mg rectal diclofenac, Group 2 received 100 mg rectal tramadol, and Group 3 received rectal glycerin suppository. The time to initiate BF and ambulation was compared between different analgesic regimens and corelated with pain score. Results: BF (both with and without support) was initiated significantly earlier in Groups 1 and 2 as compared with control Group 3 (p < 0.001). A significantly shorter time was taken to initiate BF without support in Group 1 as compared with Group 2 (p = 0.028). The time to start ambulation (both with and without assistance) was significantly lower in Groups 1 and 2 as compared with Group 3 and in Group 1 versus Group 2 (p < 0.001). A significant positive correlation was found between the time to initiate BF with support and ambulation without assistance and postoperative pain score at 0, 1, and 6 hours. Conclusion: Effective post-CS analgesia affects early initiation of BF and ambulation in the immediate postnatal period. The inclusion of rectal diclofenac suppository in post-CS analgesic regimens is a promising approach to postoperative delivery care.

Breastfeeding in the first hour of life in Brazilian private hospitals participating in a quality-of-care improvement project

BACKGROUND

The Baby-Friendly Hospital Initiative's Step 4 recommends: "support mothers to start breastfeeding as soon as possible after birth", thus contributing to the reduction of neonatal mortality. The objective of this study is to estimate the prevalence of breastfeeding in the first hour of life in private maternity hospitals participating in the "Adequate Childbirth Project", a quality-of-care improvement project, and to analyze determinants of this outcome.

METHODS

Secondary analysis of data collected by the cross-sectional evaluative "Healthy Birth Study", conducted in 2017 in 12 maternity hospitals participating in the Adequate Childbirth Project, where 4800 mothers were interviewed, and hospital records were observed. Conditions that prevented breastfeeding at birth, such as maternal HIV-infection and newborns' severe malformations, were excluded. Multiple logistic regression was performed according to a hierarchical theoretical model.

RESULTS

The prevalence of breastfeeding in the first hour of life was 58% (CI 95% 56.6-59.5%). Lower maternal education (aOR 0.643; CI 95% 0.528-0.782), lower economic status (aOR 0.687; CI 95% 0.504-0.935), cesarean section delivery (ORa 0.649; CI 95% 0.529-0.797), preterm birth (aOR 0.660; CI 95% 0.460-0.948) and non-rooming-in at birth (aOR 0.669; CI 95% 0.559-0.800) were negatively associated with the outcome. Receiving information during prenatal care about the importance of breastfeeding at birth (aOR 2.585; CI 95% 2.102-3.179), being target of the quality-of-care improvement project (aOR 1.273; CI 95% 1.065-1.522), skin-to-skin contact at birth (aOR 2.127; CI 95% 1.791-2.525) and female newborn (aOR 1.194; CI 95% 1.008-1.415) were factors positively associated with the outcome.

CONCLUSIONS

The private maternities participating in the Healthy Birth Study showed a good prevalence of breastfeeding in the first hour of life, according to WHO parameters. Prenatal guidance on breastfeeding at birth, being target of the quality-of-care improvement project and skin-to-skin contact at birth contributed to breastfeeding in the first hour of life.

Comparison of Post-Cesarean Pain Perception of General Versus Regional Anesthesia, a Single-Center Study

Background and Objectives: Pain during and after the procedure remains the leading concern among women undergoing cesarean section. Numerous studies have concluded that the type of anesthesia used during a cesarean section undoubtedly affects the intensity and experience of pain after the operation. Materials and Methods: This prospective cohort study was conducted at the Clinic for Gynecology and Obstetrics, Clinical Center "Dragisa Misovic-Dedinje", Belgrade, Serbia. Patients at term pregnancy (37-42 weeks of gestation) with an ASA I score who delivered under general (GEA) or regional anesthesia (RA) by cesarean section were included in the study. Following the procedure, we assessed pain using the Serbian McGill questionnaire (SF-MPQ), Visual Analogue Scale (VAS) and the pain attributes questionnaire at pre-established time intervals of 2, 12, and 24 h after the procedure. Additionally, time to patient's functional recovery was noted. We also recorded the time to the first independent mobilization, first oral intake, and lactation establishment. Results: GEA was performed for 284 deliveries while RA was performed for 249. GEA had significantly higher postoperative sensory and affective pain levels within intervals of 2, 12, and 24 h after cesarean section. GEA had significantly higher postoperative VAS pain levels. On pain attribute scale intensity, GEA had significantly higher postoperative pain levels within all intervals. Patients who received RA had a shorter time to first oral food intake, first independent mobilization, and faster lactation onset in contrast to GEA. Conclusions: The application of RA presented superior postoperative pain relief, resulting in earlier mobilization, shorter time to first oral food intake, and faster lactation onset in contrast to GEA.

Incidence and associated factors of acute postoperative pain within the first 24 h in women undergoing cesarean delivery at a resource-limited setting in Addis Ababa, Ethiopia: A prospective observational study

Objective:

This study aimed to assess the incidence and associated factors of acute postoperative pain after cesarean section within the first 24 h of postoperative period.

Methods:

An institutional-based prospective observational study was conducted on parturients who had undergone cesarean section in Gandhi Memorial Hospital from 1 December 2019 to 28 February 2020. A numerical rating scale was used to evaluate the incidence of acute postoperative pain. Patients having a pain score of >4 were considered having moderate-to-severe pain on numerical rating scale. Data were analyzed using SPSS version 20. Bivariable and multivariable logistic regression were used to assess the association of variables. A p value of less than 0.05 was taken as significant association with dependent variables.

Result:

In total, 290 parturients participated in the study with a response rate of 98%. Moderate-to-severe acute postoperative pain after cesarean section was 76.2% (95% confidence interval: 71%, 81%) in the first 24 h postoperatively. On multivariable analysis, previous cesarean section history (adjusted odds ratio: 2.80, 95% confidence interval: 1.40, 5.55; p = 0.003), preoperative anxiety (adjusted odds ratio: 2.70, 95% confidence interval: 1.45, 5.05; p = 0.003), transverse incision type (adjusted odds ratio: 3.35, 95% confidence interval: 1.67, 6.72; p = 0.002), and incision length (adjusted odds ratio: 2.46, 95% confidence interval: 1.24, 4.85; p = 0.009) were identified as risk factors for postoperative moderate-to-severe acute pain.

Conclusion:

The incidence of moderate-to-severe postoperative pain was high in the first 24-h postoperative period; this indicates that pain management after cesarean section was treated inadequately. History of previous cesarean section, preoperative anxiety, transverse incision, and incision length >10 cm were the factors of postoperative acute pain after cesarean section. Therefore, we suggest the study institution develop a protocol for pain management.

Enhanced Recovery after Surgery Protocol to Improve Racial and Ethnic Disparities in Postcesarean Pain Management

OBJECTIVE

The objective of this study was to assess the efficacy of an enhanced recovery after surgery (ERAS) protocol and determine its effect on racial/ethnic disparities in postcesarean pain management.

STUDY DESIGN

We performed an institutional review board-approved retrospective cohort study of scheduled cesarean deliveries before and after ERAS implementation at a single urban academic institution. Pre-ERAS, all analgesic medications were given postoperatively on patient request. The ERAS protocol included preoperative acetaminophen and celecoxib. Postoperatively, patients received scheduled nonsteroidal anti-inflammatory drugs and acetaminophen. Oral oxycodone was available as needed, and opioid patient-controlled analgesia was eliminated from the standard order set. The primary outcome was total opioid use in the first 48 hours after cesarean, pre- and post-ERAS, reported in total milliequivalents of intravenous morphine (MME). A secondary analysis of opioid use and pain scores by racial groups was also performed. Chi-square, independent t-tests, analysis of variance, Mann-Whitney U, and Kruskal-Wallis tests were used depending on variable and data normality.

RESULTS

Pre-ERAS and post-ERAS groups included 100 women each. Post-ERAS, total opioid use in 48 hours was less (40.8 vs. 8.6 MME, p < 0.001) and visual analog scale (VAS) pain scores were lower on postoperative day 1 (POD1) and 2 (POD2) (POD1 maximum at rest: 6.7 vs. 5.3, p < 0.001). Pre-ERAS pain scores differed by race with non-Hispanic Black (NHB) patients reporting the highest mean and max VAS pain scores POD1 and POD2 (POD1, maximum VAS at rest: NHB-7.4, non-Hispanic White-6.6, Hispanic-5.8, Asian-4.4, p = 0.006). Post-ERAS, there were no differences in postoperative pain scores between groups with movement on POD1 and POD2.

CONCLUSION

A standardized ERAS protocol for postcesarean pain decreases opioid use and may improve some racial disparities in postcesarean pain control.

KEY POINTS

· ERAS protocols improve postoperative pain control and lower postoperative opioid use.. · Studies show that there are racial and ethnic disparities in postpartum pain control.. · Protocols standardize care and may decrease the effects of provider implicit bias..

Post-operative pain and associated factors after cesarean section at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia: A cross-sectional study

Background

The most frequent obstetric surgery both in Ethiopia and around the world is the cesarean section (CS). Postoperative pain that is not well managed can have a major negative impact on surgical patient morbidity, delaying healing and the return to normal daily activities. Even though the cesarean section is one of the most commonly performed operations, postoperative pain after cesarean section and associated factors has not been studied.

Objective

To assess the magnitude and factors associated with postoperative pain after cesarean section at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia.

Methods

From February 1 to September 30 in 2021, a hospital-based cross-sectional study was undertaken among women who underwent cesarean deliveries at Hawassa University Comprehensive Specialized Hospital. The patient's medical file was read, and information was gathered from them using a structured questionnaire and checklist. The information was prepared for analysis by being cleaned, coded, and put into EPI Data version 3.1 before being exported to SPSS version 20. The prevalence rate and socio-demographic details were displayed using descriptive statistics. Bivariate and multivariable logistic regression analysis was done to identify the associated factors. Variables with a p-value of <0.05 were considered statistically significant.

Results

The magnitude of moderate to severe post-operative pain after a cesarean section was 89.8% (95% CI 84.7, 93.5). Duration of procedure (AOR: 3.62, 95% CI: 1.33, 15.85), type of anesthesia (AOR: 2.38, 95% CI: 1.31, 8.71), and type of analgesics administered (AOR: 2.3, 95% CI: 1.28, 19.21) were significantly associated with moderate to severe post-operative pain.

Conclusion

In this study a significant number of parturient in this study reported moderate to severe post-cesarean pain within 24 h. The duration of the procedure, the type of anesthesia used, and the type of analgesics administered were all found to be significantly associated with postoperative pain after cesarean section.

•

The magnitude of post-operative pain after a caesarean section was 89.8%.

•

About 84.2% reported moderate to severe pain at 24 h after surgery.

•

Duration of procedure was significantly associated to postoperative pain.

•

Anesthesia type used was found to be significantly associated to postoperative pain.

The effect of aromatherapy and Su Jok interventions on post-cesarean pain

OBJECTIVE

The aim of this study was to determine the effect of aromatherapy and Su Jok interventions as nonpharmacological methods of relieving pain after cesarean section.

MATERIALS AND METHODS

This randomized controlled trial was conducted with 120 women who had cesarean delivery in the gynecology and obstetrics department of a training and research hospital between February 9 and October 2, 2019. The participants were allocated to the aromatherapy group, Su Jok group, Su Jok and aromatherapy group, or control group using block randomization based on parity. Su Jok was performed using buckwheat seed; aromatherapy was applied using lavender, eucalyptus, or rose oil. Data were collected using a participant information form and pain was assessed using the Visual Analog Scale.

RESULTS

There was no significant difference between the groups in mean pain levels before or after the intervention, although the control group had less initial pain compared to the intervention groups. However, all three intervention groups showed significant decreases in pain levels immediately and 30 min after the intervention compared to pre-intervention levels (p < 0.05). The intervention in all three groups reduced the level of pain. In particular, the pain level of the Su Jok group reached from moderate to mild. There was no significant change in the control group.

CONCLUSIONS

Aromatherapy and Su Jok interventions performed separately and simultaneously in addition to routine hospital care were more effective in reducing post-cesarean pain than routine care alone.

Pentazocine with rectal diclofenac versus pentazocine alone for pain relief following caesarean delivery in Enugu, Nigeria: A randomized controlled trial

Objective

To measure postoperative pain relief following the use of rectal diclofenac combined with intramuscular pentazocine compared with intramuscular pentazocine alone in patients undergoing a caesarean delivery.

Methods

This single-blind randomized controlled trial enrolled pregnant women that had a caesarean section at the Enugu State University of Science and Technology Teaching Hospital, Enugu, Nigeria. Study participants were randomized to receive either 100 mg of rectal diclofenac given every 12 h plus 30 mg of intramuscular pentazocine given every 6 h (group A) or 60 mg of intramuscular pentazocine given every 6 h (group B). The primary outcome was the level of pain as measured using a visual analogue scale. The secondary outcomes were the level of satisfaction with pain relief and need for rescue analgesia.

Results

A total of 200 participants were randomized equally into the two groups. Participants in group A had significantly better pain control and satisfaction over the 48 h after surgery compared with group B. Significantly more of group B required rescue analgesia for breakthrough pain compared with group A.

Conclusion

Rectal diclofenac combined with intramuscular pentazocine was significantly better at controlling pain compared with pentazocine alone in the first 48 h following caesarean section.

Birth Experiences, Breastfeeding, and the Mother-Child Relationship: Evidence from a Large Sample of Mothers

BACKGROUND

It is a priority for public health professionals to improve global breastfeeding rates, which have remained low in Western countries for more than a decade. Few researchers have addressed how maternal perceptions of birth experiences affect infant feeding methods. Furthermore, mixed results have been shown in research regarding breastfeeding and mother-child bonding, and many studies are limited by small sample sizes, representing a need for further investigation.

PURPOSE

We aimed to examine the relationship between subjective birth experiences and breastfeeding outcomes, and explored whether breastfeeding affected mother-infant bonding.

METHODS

3,080 mothers up to three years postpartum completed a cross - sectional survey.

RESULTS

Mothers who had more positive birth experiences were more likely to report breastfeeding their babies. Moreover, mothers who perceived their birth as more positive were more likely to breastfeed their child for a longer period (over 9 months) than those who had more negative experiences. In line with recent research, breastfeeding behaviours were not associated with reported mother-infant bonding.

CONCLUSIONS

Mothers who reported better birth experiences were most likely to breastfeed, and breastfeed for longer. We find no evidence to suggest that feeding methods are associated with bonding outcomes.

The complex effects of maternal expectations on postpartum depressive symptoms: when does a protective factor become a risk factor?

PURPOSE

The present study assessed the effects of several prenatal maternal expectations on postpartum depression (PPD), while considering two relevant factors - incongruence between planned and actual birth and the rigidity of the birth plan - that can affect whether maternal expectations act as protective factors or risk factors for PPD.

METHODS

Primiparous women (N = 527) were recruited to a longitudinal study about women's birth choices and experiences. At time 1, during pregnancy, women completed a questionnaire assessing prenatal depression, preferred birth plan, birth plan flexibility-rigidity and maternal expectations (i.e. Natural-Fulfillment, Infant-Reflects-Mothering, Sacrifice). At time 2, two-months post-partum, they reported their actual birth mode and answered a questionnaire assessing their PPD symptoms.

RESULTS

Natural-fulfillment maternal expectations were negatively related to PPD symptoms. Yet, the interaction of high natural-fulfillment expectations with an unfulfilled birth plan and the rigidity of the birth plan, served as a risk factor for PPD symptomatology.

CONCLUSIONS

Understanding the conditions under which specific prenatal maternal expectations serve as a risk factor for PPD, can help healthcare providers identify women who are at high risk for developing PPD symptoms and plan preemptive interventions.

Factors influencing postoperative pain management among nurses in selected district hospitals in Ghana

BACKGROUND

Poorly managed postoperative pain is linked to numerous postoperative complications worldwide and in Ghana. This is due to the myriad of physical and psychological problems, such as lifelong chronic pain syndromes, impaired functionality and death.

PURPOSE

The aim of this study was to assess the barriers and factors influencing postoperative pain management by Ghanaian nurses working in four hospitals.

METHODS

A quantitative descriptive cross-sectional design was employed for this study. Participants were recruited using a multistage sampling technique by which 146 returned their questionnaires out of 194 participants. The statistical analysis of data was done with the Statistical Package of Social Sciences (SPSS) 20.0 version.

RESULTS

Findings revealed that some verbal and non-verbal cues from patients such as facial grimacing, restlessness, irritability and distress, lack of concentration and moaning or crying (verbalisation) influenced how nurses controlled postoperative pain with analgesia. The participants also identified several barriers to influence postoperative pain management by nurses.

CONCLUSION

In conclusion, postoperative pain control by nurses is influenced by several factors, and hence, nurses need to manage patients' pain effectively in Ghana and abroad using multiple approaches.

Comparison of L-Shape and Side-Lying Positions on Breastfeeding Outcomes among Mothers Delivered by Cesarean Section: A Randomized Clinical Trial

Introduction: Ineffective breastfeeding techniques is one of the factors contributing to poor breastfeeding outcomes in post-cesarean mothers. To assist post-cesarean mothers to find a comfortable breastfeeding position, a trial was conducted to compare different positions of breastfeeding in these individuals.

Methods: A randomized clinical parallel trial was carried out on primipara post-cesarean mothers admitted to All India Institute of Medical Sciences (AIIMS), Rishikesh, Uttarakhand, India. Participants were enrolled by convenience sampling technique, which was further randomized (block size= 4) and allocated to receive either "L" shape (n= 30) or side-lying (n= 30) position for breastfeeding. The assigned intervention was provided at least six times a day for four consecutive days. Data were collected using breastfeeding assessment Tool, maternal breastfeeding evaluation scale and numeric pain rating scale. Data were analyzed using SPSS software version 23.

Results: The baseline characteristics of participants in both groups were similar. The mean comparison of breastfeeding outcome and maternal satisfaction indicated no significant difference between the two positions. However, the mean scores of maternal pain were statistically significant. Hence, it was inferred that the maternal pain was significantly less in post-cesarean mothers in "L" shape compared to side-lying.

Conclusion: There is significantly less pain in post-cesarean mothers during breastfeeding in "L" shape than side-lying. Furthermore, maternal satisfaction and breastfeeding outcomes were found to be similar in both positions.

Association of Postpartum Pain Sensitivity and Postpartum Depression: A Prospective Observational Study

INTRODUCTION

Postpartum depression (PPD) is a severe psychiatric disorder that negatively affects postnatal mothers worldwide. The aim of the study is to investigate the association between postpartum pain sensitivity and PPD as well as to identify the other potential risk factors for PPD and their interconnections.

METHODS

The current study was a prospective observational clinical study that enrolled 210 singleton pregnant women in a tertiary referral hospital from January to December 2020. Postpartum pain sensitivity was assessed by the Mandarin Chinese version of the Pain Sensitivity Questionnaire (PSQ), and PSQ-C-total and PSQ-C-minor scores were collected. PPD was screened by self-reporting Edinburgh Postnatal Depression Scale (EPDS), and EPDS total score was recorded. The association between postpartum pain sensitivity and PPD, as well as the risk factors and their interconnections, was analyzed by using a combination of stratified, bivariate, correlation, receiver-operating characteristic (ROC) curve, multivariate logistic regression, and path analysis.

RESULTS

Overall, 87 of 210 mothers (41.4%) screened positive for PPD. A positive correlation between PSQ-C-total (r = 0.67) or PSQ-C-minor (r = 0.62) and EPDS scores was identified. PSQ-C-total [area under curve (AUC) 0.89, 95% CI 0.84-0.93; P < 0.0001] showed significantly higher diagnostic accuracy compared with PSQ-C-minor (AUC 0.85, 95% CI 0.80-0.90; P < 0.0001) in predicting EPDS scores ≥ 10 points. Multivariate logistic regression indicated that a high PSQ-C-total score [adjusted odds ratio (OR) 1.12, 95% CI 1.08-1.51; P < 0.001] and gestational diabetes (adjusted OR 2.68, 95% CI 0.96-7.47; P = 0.045) were independent risk factors, while breastfeeding (adjusted OR: 0.34, 95% CI 0.15-0.78; P = 0.007) and normal birth weight (adjusted OR 0.17, 95% CI 0.05-0.61; P = 0.0047) were independently associated with decreasing adjusted ORs for EPDS scores ≥ 10 points. The path analysis model indicated that PSQ-C-total scores and gestational diabetes showed bidirectional effects, while birth weight and breastfeeding only had a direct impact on EPDS scores ≥ 10 points.

CONCLUSION

Increased postpartum pain sensitivity was closely associated with EPDS scores ≥ 10 points, and PSQ-C scores could be a reliable predictor. Moreover, gestational diabetes, low occurrence of breastfeeding, and low birth weight were the risk factors for EPDS scores ≥ 10 points.

Comparison of Cradle Hold Versus Football Hold Breastfeeding Positions after Cesarean Section in Primiparous Mothers

Objective: To compare cradle hold and football hold breastfeeding positions in terms of their effects on incision pain, breastfeeding success, and patient satisfaction among primiparous breastfeeding women after cesarean section. Materials and Methods: Sixty-seven breastfeeding primiparous women who underwent cesarean section were included in this crossover study. The women were instructed to use two different breastfeeding positions sequentially and change in pain intensity before and after each session were questioned. At the end of each session breastfeeding success (using LATCH breastfeeding charting system) and maternal satisfaction were assessed. In addition, mother's most preferred position was asked at the time of discharge. Results: A statistically significant increase was found in incisional pain score after breastfeeding with cradle hold position (p < 0.001), whereas no such change was observed in association with football hold position (p = 1.000). In contrast, total LATCH score was significantly better with cradle hold position when compared with football hold position (8.7 ± 1.1 versus 8.0 ± 1.1, respectively; p < 0.001). The two positions were similar in terms of maternal satisfaction scores (p = 0.082). Majority of the mothers (74.6%) preferred cradle hold position at the time of discharge. Conclusions: Although cradle hold position was associated with increased incision pain, it provided better breastfeeding experience and was more commonly preferred, which may be attributed to lesser familiarity with the latter position. Prenatal training should be provided to mothers on all breastfeeding positions. Further studies with larger sample size are warranted to better understand the relationships between incision pain after cesarean section, breastfeeding positions, and breastfeeding success.

The Current Consideration, Approach, and Management in Postcesarean Delivery Pain Control: A Narrative Review

Optimal postoperative analgesia has a significant impact on patient recovery and outcomes after cesarean delivery. Multimodal analgesia is the core principle for cesarean delivery and pain management. For a standard analgesic regimen, the use of long-acting neuraxial opioids (e.g., morphine) and adjunct drugs, such as scheduled acetaminophen and nonsteroidal anti-inflammatory drugs, is recommended unless contraindicated. Oral or intravenous opioids should be reserved for breakthrough pain. In addition to the aforementioned use of multimodal analgesia, preoperative evaluation is critical to individualize the analgesic regimen according to the patient requirements. Risk factors for severe postoperative pain or analgesia-related adverse effects will require modifications to the standard analgesic regimen (e.g., the use of ketamine, gabapentinoids, or regional anesthetic techniques). Further investigation is required to determine analgesic drugs or dose alterations based on preoperative predictions for patients at risk of severe pain. Outcomes beyond pain and analgesic use, such as functional recovery, should be determined to evaluate analgesic treatment protocols.

Quadratus lumborum block for postoperative analgesia after cesarean section: a meta-analysis of randomized controlled trials with trial sequential analysis

The aim of this study was to assess the analgesic efficacy of QLB versus controls in women undergoing cesarean section (CS). We systematically searched Cochrane Library, PUBMED, EMBASE, VIP, WANFANG, and China National Knowledge Infrastructure. Trials were eligible if parturients received QLB during CS. GRADE system was used to assess the certainty of evidence and Trial sequential analyses (TSA) were performed to determine whether the results are supported by sufficient data. Thirteen studies involving 1269 patients were included. Compared to controls, QLB significantly reduced the cumulative postoperative intravenous opioid consumption (in milligram morphine equivalents) at 24 h (MD, - 11.51 mg; 95% CI - 17.05 to - 5.96) and 48 h (MD, - 15.87 mg; 95% CI - 26.36 to - 5.38), supported by sufficient data confirmed by TSA. The postoperative pain scores were significantly reduced by QLB at 4 h, 6 h, 12 h, 24 h, and 48 h postoperatively by QLB compared with control. Moreover, the time to first request for rescue analgesic and the incidence of PONV were also significantly reduced by QLB. The quality of evidence of most results were low and moderate assessed by GRADE.

Analgesic effects of intravenous ketamine after spinal anaesthesia for non-elective caesarean delivery: a randomised controlled trial

OBJECTIVES

This study aimed to determine if low dose intravenous ketamine is effective in reducing opioid use and pain after non-elective caesarean delivery.

DESIGN

Prospective, randomised, double-blind.

SETTING

Tertiary hospital, Bisheshwar Prasad Koirala Institute of Health Sciences, Dharan, Nepal PARTICIPANTS: 80 patients undergoing non-elective caesarean section with spinal anaesthesia.

INTERVENTIONS

Patients were allocated in 1:1 ratio to receive either intravenous ketamine 0.25 mg/kg or normal saline before the skin incision.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was the total amount of morphine equivalents needed up to postoperative 24 hours. Secondary outcome measures were postoperative pain scores, time to the first perception of pain, maternal adverse effects (nausea, vomiting, hypotension, shivering, diplopia, nystagmus, hallucination) and neonatal Apgar score at 1 and 5 min, neonatal respiratory depression and neonatal intensive-care referral.

RESULTS

The median (range) cumulative morphine consumption during the first 24 hours of surgery was 0 (0-4.67) mg in ketamine group and 1 (0-6) mg in saline group (p=0.003). The median (range) time to the first perception of pain was 6 (1-12) hours and 2 (0.5-6) hours in ketamine and saline group, respectively (p<0.001). A significant reduction in postoperative pain scores was observed only at 2 hours and 6 hours in the ketamine group compared with placebo group (p<0.05). Maternal adverse effects and neonatal outcomes were comparable between the two groups.

CONCLUSIONS

Intravenous administration of low dose ketamine before surgical incision significantly reduced the opioid requirement in the first 24 hours in patients undergoing non-elective caesarean delivery.

The efficacy of abdominal binders in reducing postoperative pain and distress after cesarean delivery: A meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the efficacy of abdominal binders in reducing postoperative pain, patient distress and surgical postoperative sequelae after cesarean delivery (CD).

METHODS

A comprehensive search in electronic databases (MEDLINE, EMBASE, and Cochrane Central) was performed up to February 2021. Selection criteria included randomized clinical trials investigating the application or not of abdominal binder after CD. The primary outcome was postoperative pain, measured using the visual analog scale (VAS) pain score. Secondary outcomes were divided into short- and long-term postoperative outcomes, including patient distress, need for additional pain medications, time to mobilization, return to normal daily activities, surgical site infection, fascial dehiscence or incisional hernia, and rectus abdominis diastasis. The summary measures were reported as mean difference with 95 % confidence intervals (CI) using the random effects model of DerSimonian and Laird. An I² (Higgins I²) value of greater than 0% was used to identify heterogeneity.

RESULTS

Four RCTs involving 601 women were included for meta-analysis: 310 (51.6 %) were randomized to the abdominal binder and 291 (48.4 %) to no abdominal binder group. There was no statistically significant difference between the two groups for VAS score either at 24 h (MD -0.97, 95 % CI -2.23 to 0.30; p = 0.13) and at 48 h (MD -0.30, 95 % CI -0.71 to 0.11; p = 0.15). Conversely, there was a significant reduction in postoperative distress (SDS) both at 24 h (MD -2.23, 95 % CI -3.77 to -0.70; p = 0.004) and 48 h (MD -2.37, 95 % CI -3.86 to -0.87; p = 0.002).

CONCLUSION

The present meta-analysis shows that the use of abdominal binders after CD significantly reduces patient distress.

A Randomized Controlled Trial of the Effect of Music During Cesarean Sections and the Early Postpartum Period on Breastfeeding Rates

Objective: The objective of this research was to study the role of music listening by mothers during a cesarean section and the postpartum period to achieve exclusive breastfeeding in the first 6 months. Methods and Study Design: This was a prospective, observational, randomized controlled trial study. A total of 185 singleton pregnant women, in at least 37 weeks of gestation, who were appointed for elective cesarean sections, were recruited. They were randomized into three groups, including pregnant women who did not listen to music (Group 1), listened to music during cesarean section (Group 2), and listened to music during cesarean section and the postpartum room for the first 2 days (Group 3). The breastfeeding results of all three groups were followed up at 7 days, 14 days, and then at months 1, 2, 3, and 6. Results: Success in exclusive breastfeeding among Groups 1, 2, and 3 and Groups 1 and 2 + 3 was not different in every lactating period (7 days-6 months). From subgroup analysis, mothers who listened to music in a private ward had more success in exclusive breastfeeding than those in a common ward. Mothers who listened to music and had an income of <20,000 baht, an educational level lower than university, planned the pregnancy, had their first pregnancy, and stayed in a private ward had more successful exclusive breastfeeding in a 6-month period than those mothers who did not listen to music, and the difference was statistically significant. Conclusions: Music listening by mothers during a cesarean section and in the postpartum ward did not enhance exclusive breastfeeding during the first 6 months of the postpartum period. However, from subgroup analysis, mothers who listened to music in a private ward had more success in exclusive breastfeeding than those in a common ward. Thai Clinical Trials Registry number was TCTR20180712001.

The effectiveness of the abdominal binder in relieving pain after cesarean delivery: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Abdominal binder is a non-pharmacological method of relieving pain after surgical procedures.

OBJECTIVES

To evaluate the effectiveness of the abdominal binder in relieving pain and distress scores after cesarean delivery (CD).

SEARCH STRATEGY

The following terms were searched: cesarean section, cesarean, caesarean, abdominal deliveries, C-section, abdominal delivery, abdominal binding, binder, and abdominal binder.

SELECTION CRITERIA

Randomized controlled trials (RCTs) with patients undergoing CD receiving an abdominal binder compared with non-users of the abdominal binder.

DATA COLLECTION AND ANALYSIS

Five electronic databases were searched until November 2019. Records were screened for eligibility. Data were extracted independently and analyzed. The main outcomes were pain and distress scores.

RESULTS

The final analysis included six RCTs. Overall effect estimate favored the abdominal binder group over the control group in the following outcomes: VAS pain scores after 24 h (mean difference [MD] -1.76; 95% confidence interval [CI] -3.14 to -0.39; P = 0.01), VAS scores after 48 h (MD -1.21; 95% CI -1.51 to -0.90; P < 0.001), distress score after 24 h (MD -1.87; 95% CI -3.01 to -0.73; P = 0.001), and distress score after 48 h (MD -1.87; 95% CI -3.07 to -0.67; P = 0.002).

CONCLUSION

The abdominal binder could be an effective, simple, non-pharmacological option of relieving pain and distress after CD.

The Clinical Effects of Abdominal Binder on Abdominal Surgery: A Meta-analysis

Objective. We conducted a meta-analysis to quantitatively evaluate the effects of abdominal binder in abdominal surgeries. Methods. Through literature retrieval in globally recognized databases (MEDLINE, EMBASE, and Cochrane Central), trials investigating the application of abdominal binder in abdominal surgeries were systematically reviewed. The main outcomes, namely, 6-minute walk test (6MWT), visual analog scale (VAS) pain score, and symptom distress scale (SDS) score, were pooled to make an overall estimation. I² index was calculated to identify heterogeneity, and sensitivity analysis was performed to validate the stability of main results and explore the source of heterogeneity. A funnel plot and Egger's test were applied to assess publication bias. Results. Ten randomized controlled trials consisting of 968 subjects were ultimately included for the pooled estimation. Abdominal binder significantly increased the distance of 6MWT with standard mean difference (SMD) of .555 (P < .001) and decreased the scores of VAS and SDS with SMD of -.979 (P < .001) and -.716 (P < .001), respectively. Despite of the significant heterogeneity indicated by I² index statistic, the results of sensitivity analysis revealed the reliability of the main conclusions. While we identified no obvious publication bias regarding 6MWT (Egger's test P = .321), it seemed that significant publication biases existed with respect to the estimation of VAS (P < .001) and SDS (P = .006). Conclusion. The current meta-analysis verified that abdominal binder efficiently promoted recovery after abdominal surgeries in terms of facilitating mobilization, alleviating pain, and reducing postoperative distress. More rigorously designed clinical trials with large sample size are expected to further elaborate its clinical value.

The efficacy of transcutaneous electrical nerve stimulation therapy in pain control after cesarean section delivery associated with uterine contractions and abdominal incision

Objectives

This study aims to investigate the effects of transcutaneous electrical nerve stimulation (TENS) therapy on the intensity of pain associated with uterine contractions and abdominal incision in patients undergoing cesarean section (C-section) delivery.

Patients and methods

This single-blind, prospective, randomized-controlled study included a total of 90 female patients (mean age 30.5 years; range, 25 to 36 years) who had a scheduled C-section delivery between November 2017 and April 2018. Forty-five postpartum patients were randomly assigned into the treatment group (Group 1) and TENS electrodes were placed below and above the abdominal incision. The control group (n=45) consisted of 45 patients who had a scheduled C-section (Group 2) (n=45) and received routine follow-up care. The Visual Numeric Scale (VNS) scores were obtained separately for abdominal, low back, and groin pain at baseline (within 1 h after C-section before the TENS replacement), at postpartum 2, 6, 24, and 48 h. In addition to instant scoring, the percentages of change in pain scores from baseline were also calculated for each time points.

Results

Data of a total of 87 patients were analyzed. No statistically significant difference was found in the baseline VNS scores measured in any body regions between the groups (p>0.05). However, there was a statistically significant difference in the instant VNS scores for abdominal pain at 2, 6, 24, and 48 h in favor of Group 1 (p<0.05). No significant differences were found in the instant VNS scores for low back and groin pain (p>0.05). The comparison of changes in pain scores from baseline (% change) over time between the groups revealed a statistically significant difference in favor of Group 1 in all VNS scores for abdominal, low back, and groin pain at 2, 6, 24, and 48 h (p<0.05).

Conclusion

Our study results suggest that TENS is an effective and safe non-invasive, non-pharmacological treatment modality. It may be preferred as an alternative method in pain control in postpartum women after C-section delivery.
