Postoperative Pain After Cesarean Birth Affects Breastfeeding and Infant Care

Mode of first delivery and postpartum weight retention at 1 year

BACKGROUND

The prevalence of obesity in the US has increased markedly in women in their reproductive years over the past 3 decades, partially due to higher rates of postpartum weight retention. This was a prospective cohort study that investigated mode of delivery as an independent risk factor for postpartum weight retention at 1 year postpartum.

METHODS

Data from 2500 first-time mothers, aged 18-35 with singleton pregnancies were included in this analysis. Postpartum weight retention was measured at 1 year after delivery and was defined as weight at 1 year compared to weight just before becoming pregnant. Logistic regression models assessed the association between mode of first delivery and subsequent weight retention of 10 pounds or more, adjusting for key confounders including pre-pregnancy body mass index, gestational weight gain, age, education, poverty status, smoking, race/ethnicity, gestational age, pregnancy complications, breastfeeding and exercise habits during pregnancy and in the first year after delivery.

RESULTS

At 12 months after delivery the women who had delivered by cesarean were more likely to have a postpartum weight retention of 10 pounds or more (27.9%), than those who had delivered vaginally (22.2%), unadjusted OR 1.35 (95% CI 1.11-1.65, p=.003). Even after controlling for confounding variables, mode of delivery remained significantly associated with postpartum weight retention of 10 pounds or more, adjusted OR 1.30 (95% CI 1.04-1.62, p=.02).

CONCLUSIONS

Cesarean delivery at first childbirth is associated with increased risk of weight retention of 10 pounds or more at 1 year postpartum.

The analgesic efficacy of IV acetaminophen for acute postoperative pain in C-section patients: a randomized, double-blind, placebo-controlled study

Background: The rate of cesarean delivery is on the rise in the USA. Satisfactory postoperative analgesia remains a top priority for cesarean delivery. Multimodal analgesia with a reduction in opioid consumption and improvement in patient satisfaction is a goal for anesthesiologists caring for this patient population. Our study sought to assess whether IV acetaminophen in four divided doses over 24 h decreased pain scores and opioid requirements in patients undergoing cesarean delivery with neuraxial anesthesia.Methods: 66 patients undergoing elective cesarean delivery under spinal anesthesia with hyperbaric bupivacaine 12 mg, fentanyl 10 µg, and preservative-free morphine 150 µg were randomized to receive either IV acetaminophen or IV placebo for four consecutive doses in the first 24 h postoperatively. The need for rescue medication using morphine equivalence, pain scores, patient satisfaction, and side effects were assessed by a blinded researcher in the first 24 and 48 h postoperatively.Results: There was no difference in opioid requirements in the acetaminophen versus placebo group, 44.32 ± 23 mg versus 47.59 ± 28 mg (p = .607), respectively at 24 h. There was also no difference at 48 h, 57.95 ± 20 mg versus 56.59 ± 22 mg (p = .795). Postoperative pain scores, patient satisfaction, and adverse events were similar in both groups as well.Conclusions: The results of this study failed to demonstrate any additional benefits of administering multiple doses of IV acetaminophen for treating postoperative pain in patients who have undergone CS surgery and receiving intra-thecal morphine as part of their anesthesia and analgesia.Trial Registry number: NCT02069184.

Is Activity Tracker-Measured Ambulation an Accurate and Reliable Determinant of Postoperative Quality of Recovery? A Prospective Cohort Validation Study

BACKGROUND

Quality of recovery (QOR) instruments measure patients' ability to return to baseline health status after surgery. Whether, and the extent to which, postoperative ambulation contributes to QOR is unclear, in part due to the lack of valid tools to measure ambulation in clinical settings. This cohort study of the cesarean delivery surgical model examines the accuracy and reliability of activity trackers in quantifying early postoperative ambulation and investigates the correlation between ambulation and QOR.

METHODS

A prospective cohort of 200 parturients undergoing cesarean delivery between July 2015 and June 2017 was fitted with wrist-worn activity trackers immediately postpartum. The trackers were collected 24 hours later, along with QOR assessments (QoR-15 scale). The relationship between QOR and various covariates, including ambulation, was explored using multivariable linear regression and Spearman correlation (ρ). Forty-eight parturients fitted with 2 trackers also completed a walk exercise accompanied by a step-counting assessor, to evaluate accuracy, inter-, and intradevice reliability using interclass correlation (ICC).

RESULTS

Compared to step counting, activity trackers had high accuracy (ICC = 0.93) and excellent inter- and intradevice reliability (ICC = 0.98 and 0.96, respectively). Correlation analysis suggested that early ambulation is moderately correlated with postcesarean QoR-15 scores, with a ρ (95% confidence interval) equivalent to 0.56 (0.328-0.728). Regression analysis suggested that ambulation is a determinant of postcesarean QoR-15 scores, with an effect estimate (95% confidence interval) equivalent to 0.002 (0.001-0.003). Ambulation was also associated with all QoR-15 domains, except psychological support. The patient's acceptable symptom state (subjective threshold for good ambulation) in the first 24 hours was 287 steps.

CONCLUSIONS

This study demonstrated the accuracy and reliability of activity trackers in measuring ambulation in clinical settings and suggested that postoperative ambulation is a determinant of postoperative QOR. A hypothetical implication of our findings is that interventions that improve ambulation may also help to enhance QOR, but further research is needed to establish a causal relationship.

Relationship between caesarean section and breastfeeding: evidence from the 2013 Turkey demographic and health survey

Background

The mode of delivery influences breastfeeding practices. High rates of caesarean section and low breastfeeding rates are important public health concerns for all developing countries. This study aimed to determine the relationship between caesarean section and early breastfeeding practices among primiparae.

Methods

Data for primiparae with a singleton birth (N = 777) obtained from the 2013 Turkey Demographic and Health Survey were used in this retrospective cohort study. Early initiation of breastfeeding within one hour of delivery and exclusive breastfeeding during the first three days following birth were evaluated. Standardised incidence rates and standardised rate ratios of non-early initiation of breastfeeding and non-exclusive breastfeeding were calculated according to the mode of delivery.

Results

The late initiation of breastfeeding and non-exclusive breastfeeding incidence rates were 42.7 and 41.0%, respectively. The standardised incidence rate of late initiation of breastfeeding among women with vaginal delivery was 35.34%, versus 50.49% among those with caesarean delivery. The standardised rate ratios for late initiation of breastfeeding and non-exclusive breastfeeding were 1.428 (95% confidence interval (CI): 1.212–1.683) and 1.468 (95% CI: 1.236–1.762), respectively. Women who underwent caesarean section had a higher risk of late initiation of breastfeeding and non-exclusive breastfeeding during the three days following delivery, after controlling for sociodemographic and delivery-related factors.

Conclusions

This study provides useful evidence for the implementation of strategies to prevent unnecessary caesarean sections, which negatively affect not only maternal health but also neonatal health. The promotion of mother-friendly policies by healthcare institutions, implemented in a baby-friendly manner, is essential.

Women's psychosocial outcomes following an emergency caesarean section: A systematic literature review

Background

Given the sudden and unexpected nature of an emergency caesarean section (EmCS) coupled with an increased risk of psychological distress, it is particularly important to understand the psychosocial outcomes for women. The aim of this systematic literature review was to identify, collate and examine the evidence surrounding women’s psychosocial outcomes of EmCS worldwide.

Methods

The electronic databases of EMBASE, PubMed, Scopus, and PsycINFO were searched between November 2017 and March 2018. To ensure articles were reflective of original and recently published research, the search criteria included peer-reviewed research articles published within the last 20 years (1998 to 2018). All study designs were included if they incorporated an examination of women’s psychosocial outcomes after EmCS. Due to inherent heterogeneity of study data, extraction and synthesis of both qualitative and quantitative data pertaining to key psychosocial outcomes were organised into coherent themes and analysis was attempted.

Results

In total 17,189 articles were identified. Of these, 208 full text articles were assessed for eligibility. One hundred forty-nine articles were further excluded, resulting in the inclusion of 66 articles in the current systematic literature review. While meta-analyses were not possible due to the nature of the heterogeneity, key psychosocial outcomes identified that were negatively impacted by EmCS included post-traumatic stress, health-related quality of life, experiences, infant-feeding, satisfaction, and self-esteem. Post-traumatic stress was one of the most commonly examined psychosocial outcomes, with a strong consensus that EmCS contributes to both symptoms and diagnosis.

Conclusions

EmCS was found to negatively impact several psychosocial outcomes for women in particular post-traumatic stress. While investment in technologies and clinical practice to minimise the number of EmCSs is crucial, further investigations are needed to develop effective strategies to prepare and support women who experience this type of birth.

Comparison of Postoperative Opioid Consumption and Pain Scores in Primary Versus Repeat Cesarean Delivery in Opioid Naïve Patients

BACKGROUND

Cesarean deliveries represent a large percentage of deliveries worldwide. Patients undergoing repeat cesarean deliveries are known to have increased risks for surgical complications. However, little is known regarding potential differences in pain. We sought to compare postoperative opioid consumption and pain scores in opioid naïve patients undergoing primary versus repeat non-emergent cesarean delivery.

METHODS

This was a retrospective cohort study. Patient inclusion criteria included: having a non-emergent cesarean delivery, receiving a spinal procedure for surgical anesthesia without general anesthesia, and following the same postoperative pain management protocols. Exclusion criteria included: history of opioid tolerance, illicit drug use, or prior, non-obstetric, major abdominal surgery. The primary outcome marker was total morphine equivalents consumed 0-72 h post-procedure compared between the primary versus repeat cesarean delivery groups. Secondary outcome markers were opioid consumption and pain scores in 24-h period increments for the first 72 h postoperatively.

RESULTS

1617 patients were screened. 217 primary and 377 repeat cesarean deliveries met criteria for comparison. Reduced opioid consumption was demonstrated for the total opioid consumption 0-72 h for the repeat cesarean delivery group (median = 35) compared to the primary cesarean delivery group (median = 58), p = 0.0005. When divided into 24-h periods, differences were demonstrated for the 24-48 and 48-72 h periods but not the 0-24 h period. Pain scores did not differ statistically.

CONCLUSION

Opioid naïve obstetric patients who undergo non-emergent repeat cesarean delivery demonstrate lower opioid consumption in the postoperative period. Providers should be aware of this potential difference in order to better educate patients and provide adequate pain management.

HIGHLIGHTS

The study reviewed differences in opioid consumption between primary and repeat cesarean deliveries. All patients received the same protocol for spinal dosage and pain management. Repeat cesarean deliveries were associated with lower opioid consumption.

Neonatal weight loss and gain patterns in caesarean section born infants: integrative systematic review

There is evidence that caesarean section delivery can impact on neonatal weight loss and weight gain patterns in the first 5 days of life. We conducted an integrative systematic review to examine the association of mode of delivery on early neonatal weight loss. Pubmed, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Excerpta Medica dataBASE, and Medical Literature Analysis and Retrieval System Online were searched for relevant papers published before June 2019. Reference lists from the relevant papers were then backwards and forwards searched. As neonatal weight loss was reported in different formats, a meta‐analysis could not be carried out. Most studies did not distinguish between elective and emergency caesarean sections or instrumental and nonassisted vaginal deliveries. Seven papers were included. All papers except one found that caesarean section was associated with higher weight loss in the early days of life. Two papers presented data from studies on babies followed up to 1 month. One study found that on day 25, babies born by caesarean section had significantly higher weight gain than those born vaginally, while another found that by day 28, babies born vaginally gained more weight per day (11.9 g/kg/day) than those born by caesarean section (10.9 g/kg/day; p = .02). Overall, infants born by caesarean section lost more weight than those born vaginally, but due to the small number of studies included, more are needed to look at this difference and why it may occur. This discrepancy in weight between the two groups may be corrected over time, but future studies will need larger sample sizes and longer follow‐up periods to examine this.

Influence of Abdominal Binder Usage after Cesarean Delivery on Postoperative Mobilization, Pain and Distress: A Randomized Controlled Trial

Objective

The purpose of the present study was to determine the effect of abdominal binder usage on mobilization, postoperative pain, and distress after cesarean delivery.

Materials and Methods

This prospective randomized controlled study was conducted between September 1, 2017 and January 31, 2018 at Bakirkoy Dr. Sadi Konuk Education and Research Hospital, Istanbul, Turkey. A total of 89 women undergoing elective cesarean were randomized to the study (binder, n=45) or control (no binder, n=44) groups. Patients in the study group were fitted with a binder before leaving the operating room. Mobilization (6-minute walk test), postoperative pain (measured by Short-Form McGill Pain Questionnaire and Visual Analog Scale), and perceived distress status of both groups were evaluated within 8^th (first mobilization time), 24^th, and 48^th h of surgery.

Results

We found that the binder group (BG) walked longer than the control group during the 6-minute walking distance test. At the first mobilization time (postoperative 8^th h), the BG (99.4±27.3 m) covered significantly more distance than the control group (81.0±22.2 m) (p=0.001) in the walking distance test. At postoperative 24^th h, the McGill pain score in the BG was significantly lower than that in the control group (p=0.004). For all three test times, the Symptom Distress Scale of the BG was lower than that of the control group (postoperative 8^th h p=0.024, 24^th h p<0.001, and 48^th h p<0.001).

Conclusion

The evidence is consistent with abdominal binder usage after cesarean section decreasing the feeling of distress and increasing mobility.

Impact of caesarean section on breastfeeding indicators: within-country and meta-analyses of nationally representative data from 33 countries in sub-Saharan Africa

OBJECTIVE

To examine the impact of caesarean section on breastfeeding indicators-early initiation of breastfeeding, exclusive breastfeeding under 6 months and children ever breastfed (at least once)-in sub-Saharan Africa.

DESIGN

Secondary analysis of Demographic and Health Surveys (DHS).

SETTING

Thirty-three low-income and middle-income countries with a survey conducted between 2010 and 2017/2018.

PARTICIPANTS

Women aged 15-49 years with a singleton live last birth during the 2 years preceding the survey.

MAIN OUTCOME MEASURES

We analysed the DHS data to examine the impact of caesarean section on breastfeeding indicators using the modified Poisson regression models for each country adjusted for potential confounders. For each breastfeeding indicator, the within-country adjusted prevalence ratios (aPR) were pooled in random-effects meta-analysis.

RESULTS

The within-country analyses showed, compared with vaginal birth, caesarean section was associated with aPR for early initiation of breastfeeding that ranged from 0.24 (95% CI 0.17 to 0.33) in Tanzania to 0.89 (95% CI 0.78 to 1.00) in South Africa. The aPR for exclusive breastfeeding under 6 months ranged from 0.58 (95% CI 0.34 to 0.98) in Angola to 1.93 (95% CI 0.46 to 8.10) in Cote d'Ivoire, while the aPR for children ever breastfed ranged from 0.91 (95% CI 0.82 to 1.02) in Gabon to 1.02 (95% CI 0.99 to 1.04) in Gambia. The meta-analysis showed caesarean section was associated with a 46% lower prevalence of early initiation of breastfeeding (pooled aPR, 0.54 (95% CI 0.48 to 0.60)). However, meta-analysis indicated little association with exclusive breastfeeding under 6 months (pooled aPR, 0.94 (95% CI 0.88 to 1.01)) and children ever breastfed (pooled aPR, 0.98 (95% CI 0.98 to 0.99)) among caesarean versus vaginally born children.

CONCLUSIONS

Caesarean section had a negative influence on early initiation of breastfeeding but showed little difference in exclusive breastfeeding under 6 months and children ever breastfed in sub-Saharan Africa.

Caesarean delivery: Bringing more than just a bundle of joy

Background: Chronic postsurgical pain (CPSP) is a potential complication of all surgical procedures, including caesarean delivery (CD). Psychological factors such as anxiety and depression with negative coping strategies are known to increase the risk of the development of CPSP.

Aim: This short review will appraise some additional features that are unique to CD and assess the interplay between them and persisting pain.

Methods: This is a narrative review with a focus on describing relevant features associated with the development of CPSP after CD.

Results: Hormone changes, postpartum depression, breastfeeding, and sleep disturbance each may affect the mother’s pain in the short and long term. Together they have the potential to negatively impact the mother–infant bond.

Conclusions: In the weeks after delivery, pain, depression, and poor sleep negatively impact the mother’s quality of life and her ability to care for, and bond with, her baby. This represents a critical time for the emotional, social, and behavioral development of the infant. Far-reaching benefits for the whole family may be realized by the early identification and management of persisting postoperative pain and postpartum depression.

Predicting Severity of Acute Pain After Cesarean Delivery: A Narrative Review

Cesarean delivery is one of the most common surgical procedures in the United States, with over 1.3 million performed annually. One-fifth of women who undergo cesarean delivery will experience severe pain in the acute postoperative period, increasing their risk of developing chronic pain and postpartum depression, and negatively impacting breastfeeding and newborn care. A growing body of research has investigated tools to predict which patients will experience more severe pain and have increased analgesic consumption after cesarean delivery. These include quantitative sensory testing, assessment of wound hyperalgesia, response to local anesthetic infiltration, and preoperative psychometric evaluations such as validated psychological questionnaires and simple screening tools. For this review, we searched MEDLINE, the Cochrane database, and Google Scholar to identify articles that evaluated the utility of various tools to predict severe pain and/or opioid consumption in the first 48 hours after cesarean delivery. Thirteen articles were included in the final review: 5 utilizing quantitative sensory testing, including patient responses to pressure, electrical, and thermal stimuli; 1 utilizing hyperalgesia testing; 1 using response to local anesthetic wound infiltration; 4 utilizing preoperative psychometric evaluations including the State-Trait Anxiety Inventory, the Pain Catastrophizing Scale, the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, and simple questionnaires; and 2 utilizing a combination of quantitative sensory tests and psychometric evaluations. A number of modalities demonstrated statistically significant correlations with pain outcomes after cesarean delivery, but most correlations were weak to modest, and many modalities might not be clinically feasible. Response to local anesthetic infiltration and a tool using 3 simple questions enquiring about anxiety and anticipated pain and analgesic needs show potential for clinical use, but further studies are needed to evaluate the utility of these predictive tests in clinical practice.

Comparison of the breastfeeding outcomes and self-efficacy in the early postpartum period of women who had given birth by cesarean under general or spinal anesthesia

OBJECTIVES

This study was conducted to compare the breastfeeding outcomes and self-efficacy in the early postpartum period of women who had given birth by cesarean under general (GA) or spinal anesthesia (SA).

METHODS

This descriptive study was conducted with 190 women who had given birth under GA and SA at a training and research hospital. The data of the study were collected with the "Data Collection Form", "LATCH Breastfeeding Assessment Tool" and the "Breastfeeding Self-Efficacy Scale- Short Form (BSES-SF)".

RESULTS

The time to first breastfeeding of the newborns was 78.71 ± 126.9 min and 23.7% of the women breastfed within 30 min. Those who gave birth under SA breastfed their newborn infants statistically significantly earlier (p < .05). However, there was no statistical difference between women giving birth by cesarean under GA and SA and their score medians from the LATCH or the BSES-SF (p > .05).

CONCLUSION

The percentage of women breastfeeding their infants within the first half hour and the self-efficacy and success rate was higher among women who gave birth under SA than those who had cesarean under GA. However, breastfeeding behaviors were not at the desired level in either group. Health care professionals should therefore support women who undergo a cesarean and especially those who give birth under GA to increase their breastfeeding success and self-efficacy.

The Practice of Exclusive Breastfeeding Can Reduce Frequency of Sick Children and Improve the Productivity of Health-Care Provider Mothers: Study in Samarinda, Indonesia

Sick children can be a reason a mother is absent from work or does not work optimally. This study aims to look at the relationship between exclusive breastfeeding practices and frequency of sick children and the productivity of health-care provider mothers. This quantitative study was done using a sample of 160 health-care provider mothers from hospitals in cities and districts in Samarinda, Indonesia. Data analysis was approached using Chi-square test for categorical variables. There is a significant relationship between the practice of exclusive breastfeeding and the frequency of sick children and the productivity of health-care provider mothers (p = 0.002). The results showed that the scores of OR on the frequency variable of sick children and maternal-productivity variables are 3.22 and 2.99, respectively. The practice of exclusive breastfeeding can reduce the frequency of sick children and the productivity of health-care provider mothers. The health-care provider mothers play a role in promoting exclusive breastfeeding and as role models in providing support for the application of the Baby-Friendly Hospital Initiative with "Ten Steps to Successful Breastfeeding". There is a need for regulations regarding maternity and breastfeeding leave regardless of employment status.

Ultrasound-guided bilateral quadratus lumborum block vs. intrathecal morphine for postoperative analgesia after cesarean section: a randomized controlled trial

Background

Adequate pain control after cesarean section (CS) is crucial for mothers caring for newborns, and early ambulation to avoid thromboembolism and chronic abdominal and pelvic pain. This randomized controlled trial compared the efficacy of quadratus lumborum block (QLB) and intrathecal morphine (ITM) for analgesia after CS.

Methods

Ninety women at ≥ 37 weeks pregnancy scheduled for elective CS were enrolled. All patients received spinal anesthesia and post-operative QLB. They were randomly allocated to Control (anesthesia: 0.1 ml saline, QLB: 24 ml saline), ITM (anesthesia: 0.1 mg morphine, QLB: 24 ml saline), or QLB groups (anesthesia: 0.1 ml saline, QLB: 24 ml 0.375% ropivacaine). Integrated analgesia score (IAS) and numerical rating scale (NRS) scores at rest and during movement, morphine requirements in the first 48 h, time to first morphine dose and morphine-related side effects were recorded.

Results

IASs and NRS scores at rest and during movement were significantly lower in QLB and ITM group than in Control group. Moreover, IASs and NRS scores at rest and during movement were lower in QLB group than in ITM group. Time to first morphine dose was significantly longer in QLB group than in ITM and Control group. Furthermore, morphine requirements in the first 48 h were significantly lower in QLB group than ITM and Control group. Incidence of morphine-related side effects was significantly higher in ITM group than in QLB and Control group.

Conclusions

QLB and ITM are effective analgesic regimens after CS. However, QLB provides better long-lasting analgesia and reduced total postoperative morphine consumption.

Antenatal depressive symptoms and early initiation of breastfeeding in association with exclusive breastfeeding six weeks postpartum: a longitudinal population-based study

Background

Depressive symptoms negatively impact on breastfeeding duration, whereas early breastfeeding initiation after birth enhances the chances for a longer breastfeeding period. Our aim was to investigate the interplay between depressive symptoms during pregnancy and late initiation of the first breastfeeding session and their effect on exclusive breastfeeding at six weeks postpartum.

Methods

In a longitudinal study design, web-questionnaires including demographic data, breastfeeding information and the Edinburgh Postnatal Depression Scale (EPDS) were completed by 1217 women at pregnancy weeks 17–20, 32 and/or at six weeks postpartum. A multivariable logistic regression model was fitted to estimate the effect of depressive symptoms during pregnancy and the timing of the first breastfeeding session on exclusive breastfeeding at six weeks postpartum.

Results

Exclusive breastfeeding at six weeks postpartum was reported by 77% of the women. Depressive symptoms during pregnancy (EPDS> 13); (OR:1.93 [1.28–2.91]) and not accomplishing the first breastfeeding session within two hours after birth (OR: 2.61 [1.80–3.78]), were both associated with not exclusively breastfeeding at six weeks postpartum after adjusting for identified confounders. Τhe combined exposure to depressive symptoms in pregnancy and late breastfeeding initiation was associated with an almost 4-fold increased odds of not exclusive breastfeeding at six weeks postpartum.

Conclusions

Women reporting depressive symptoms during pregnancy seem to be more vulnerable to the consequences of a postponed first breastfeeding session on exclusive breastfeeding duration. Consequently, women experiencing depressive symptoms may benefit from targeted breastfeeding support during the first hours after birth.

The Analgesic Efficacy of Nonsteroidal Anti-inflammatory Agents (NSAIDs) in Patients Undergoing Cesarean Deliveries: A Meta-Analysis

BACKGROUND AND OBJECTIVES

Postoperative pain after cesarean delivery, which accounts for approximately 1 in 3 live births in the United States, can be severe in many patients. Nonsteroidal anti-inflammatory agents (NSAIDs) are potent analgesics that are effective in the treatment of postoperative pain. In this meta-analysis, we assessed the analgesic efficacy of NSAIDs in postoperative cesarean delivery patients.

METHODS

An electronic literature search of the Library of Medicine's PubMed, Cochrane CENTRAL, Scopus, and EMBASE databases was conducted in May 2013 and updated in January 2015 (Appendix, Supplemental Digital Content 1, http://links.lww.com/AAP/A174). Searches were limited to randomized controlled trials. The primary outcome variable was visual analog scale or numerical rating scale pain scores. Secondary outcomes included cumulative postoperative opioid consumption and opioid-related adverse effects (drowsiness/sedation, nausea, and vomiting). Data extraction was performed independently by 2 reviewers. Extracted data were input into Review Manager.

RESULTS

Twenty-two randomized controlled trials compared a NSAID (n = 639) to a control (n = 674). Patients in the NSAID group versus control reported lower pain scores at 12 hours (P = 0.003) and at 24 hours (P < 0.001). Subgroup analysis showed a significant difference in pain scores at 24 hours, with patients receiving NSAIDs via intravenous/intramuscular (P < 0.001) route, but not the oral (P = 0.39) or rectal routes (P = 0.99). Significantly lower average pain scores were reported for pain with movement at 24 hours in the NSAID group (P = 0.001). Patients in the NSAID group versus controls consumed significantly less opioids (P < 0.001) and had significantly less drowsiness/sedation (P = 0.03), but there was no significant difference between the groups with regard to nausea or vomiting (P = 0.48 and P = 0.17, respectively).

CONCLUSIONS

The perioperative use of NSAIDs in cesarean delivery patients will result in a significantly lower pain scores, less opioid consumption, and less drowsiness/sedation but no difference in nausea or vomiting compared to those who did not receive NSAIDs. Further research should address the optimal NSAID regimen and examine the effect of improved analgesia on patient-centered outcomes such as patient satisfaction and quality of breastfeeding.

Using Activity Trackers to Quantify Postpartum Ambulation

Background

Early postoperative ambulation is associated with enhanced functional recovery, particularly in the postpartum population, but ambulation questionnaires are limited by recall bias. This observational study aims to objectively quantify ambulation after neuraxial anesthesia and analgesia for cesarean delivery and vaginal delivery, respectively, by using activity tracker technology. The hypothesis was that vaginal delivery is associated with greater ambulation during the first 24 h postdelivery, compared to cesarean delivery.

Methods

Parturients having first/second cesarean delivery under spinal anesthesia or first/second vaginal delivery under epidural analgesia between July 2015 and December 2016 were recruited. Patients with significant comorbidities or postpartum complications were excluded, and participants received standard multimodal analgesia. Mothers were fitted with wrist-worn activity trackers immediately postdelivery, and the trackers were recollected 24 h later. Rest and dynamic postpartum pain scores at 2, 6, 12, 18, and 24 h and quality of recovery (QoR-15) at 12 and 24 h were assessed.

Results

The study analyzed 173 patients (cesarean delivery: 76; vaginal delivery: 97). Vaginal delivery was associated with greater postpartum ambulation (44%) compared to cesarean delivery, with means ± SD of 1,205 ± 422 and 835 ± 381 steps, respectively, and mean difference (95% CI) of 370 steps (250, 490; P &lt; 0.0001). Although both groups had similar pain scores and opioid consumption (less than 1.0 mg of morphine), vaginal delivery was associated with superior QoR-15 scores, with 9.2 (0.6, 17.8; P = 0.02) and 8.2 (0.1, 16.3; P = 0.045) differences at 12 and 24 h, respectively.

Conclusions

This study objectively demonstrates that vaginal delivery is associated with greater early ambulation and functional recovery compared to cesarean delivery. It also establishes the feasibility of using activity trackers to evaluate early postoperative ambulation after neuraxial anesthesia and analgesia.

Erector spinae plane block for analgesia after lower segment caesarean section: Case report

Effective postoperative analgesia after emergency caesarean section is important because it provides early recovery, ambulation and breast-feeding. The ultrasound-guided erector spinae plane block has been orginally described for providing thoracic analgesia at the T5 transverse process by Forero et al. We performed post-operative bilateral erector spinae plane blocks with 20ml bupivacaine 0.25% at the level of the T9 transverse process in a pregnant woman after caesarean section. In this report, we described that bilateral erector spinae plane block at T9 level provides effective and long-lasting postoperative analgesia for lower abdominal surgery.

Lactation Support Services and Breastfeeding Initiation: Evidence from the Affordable Care Act

OBJECTIVE

Despite substantial evidence of the benefits of breastfeeding for both mothers and children, rates of sustained breastfeeding in the United States are quite low. This study examined whether mandated coverage of lactation support services under the Affordable Care Act (ACA) affects breastfeeding behavior.

DATA SOURCE

We studied the census of U.S. births included in the National Vital Statistics System from 2009 to 2014.

STUDY DESIGN

We used regression-adjusted difference-in-differences (DD) to examine changes in breastfeeding rates for privately insured mothers relative to those covered by Medicaid. We adjusted for several health and sociodemographic measures. We also examined the extent to which the effect varied across vulnerable populations-by race/ethnicity, maternal education, WIC status, and mode of delivery.

PRINCIPAL FINDINGS

Results suggest that the ACA mandate increased the probability of breastfeeding initiation by 2.5 percentage points, which translates into about 47,000 more infants for whom breastfeeding was initiated in 2014. We find larger effects for black, less educated, and unmarried mothers.

CONCLUSIONS

The Affordable Care Act-mandated coverage of lactation services increased breastfeeding initiation among privately insured mothers relative to mothers covered by Medicaid. The magnitude of the effect size varied with some evidence of certain groups being more likely to increase breastfeeding rates.

Association of postoperative nausea/vomiting and pain with breastfeeding success

Background

Successful breastfeeding is a goal set forth by the World Health Organization to improve neonatal care. Increasingly, patients express the desire to breastfeed, and clinicians should facilitate successful breastfeeding. The primary aim of this study is to determine if postoperative nausea and vomiting (PONV) or postoperative pain are associated with decreased breastfeeding success after cesarean delivery.

Methods

This is a historical cohort study using the Stony Brook Elective Cesarean Delivery Database. Self-reported breastfeeding success at 4 weeks postoperative was analyzed for associations with postoperative antiemetic use and postoperative pain scores. Breastfeeding success was also analyzed for associations with patient factors and anesthetic medications.

Results

Overall, 86% of patients (n = 81) who intended on breastfeeding reported breastfeeding success. Breastfeeding success was not associated with postoperative nausea or vomiting as measured by post anesthesia care unit antiemetic use (15% use in successful vs. 18% use in unsuccessful, p = 0.67) or 48-h antiemetic use (28% use in successful group vs 36% use in unsuccessful group, p = 0.732). Pain visual analog scale scores at 6, 12 and 24 h postoperatively were not significantly different between patients with or without breastfeeding success. Breastfeeding success was associated with having had at least 1 previous child (86% vs 36%, p < 0.001). Patients with asthma were less likely to have breastfeeding success (45% vs 4%, p = 0.002).

Conclusions

Efforts to improve PONV and pain after cesarean delivery may not be effective in improving breastfeeding success. To possibly improve breastfeeding rates, resources should be directed toward patients with no previous children and patients with asthma.

Risk factors for exclusive breastfeeding lasting less than two months-Identifying women in need of targeted breastfeeding support

BACKGROUND

Breastfeeding rates in Sweden are declining, and it is important to identify women at risk for early cessation of exclusive breastfeeding.

OBJECTIVE

The aim of this study was to investigate factors associated with exclusive breastfeeding lasting less than two months postpartum.

METHODS

A population-based longitudinal study was conducted at Uppsala University Hospital, Sweden. Six hundred and seventy-nine women were included in this sub-study. Questionnaires were sent at five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration as well as several other background variables. The main outcome measure was exclusive breastfeeding lasting less than two months postpartum. Multivariable logistic regression analysis was used in order to calculate adjusted Odds Ratios (AOR) and 95% Confidence Intervals (95% CI).

RESULTS

Seventy-seven percent of the women reported exclusive breastfeeding at two months postpartum. The following variables in the multivariate regression analysis were independently associated with exclusive breastfeeding lasting less than two months postpartum: being a first time mother (AOR 2.15, 95% CI 1.32-3.49), reporting emotional distress during pregnancy (AOR 2.21, 95% CI 1.35-3.62) and giving birth by cesarean section (AOR 2.63, 95% CI 1.34-5.17).

CONCLUSIONS

Factors associated with shorter exclusive breastfeeding duration were determined. Identification of women experiencing emotional distress during pregnancy, as well as scrutiny of caregiving routines on cesarean section need to be addressed, in order to give individual targeted breastfeeding support and promote longer breastfeeding duration.

Intensive care nurses' experiences of infants and partners' presence on the postoperative ward after an emergency caesarean section; An interview study

It is evident that immediate skin-to-skin care after birth has the potential to improve breastfeeding outcomes and maternal satisfaction after a caesarean section; hence partners and infants should be present on the postoperative ward.

OBJECTIVE

To investigate the intensive care nurses' experiences of having the infant and partner present on the postoperative ward after emergency caesarean sections.

DESIGN

Interviews with semi-structured interviews were conducted and analysed using qualitative content analysis.

SETTING

The interviews were conducted at a hospital in Stockholm, Sweden; where close to 10,000 births occur each year. After a caesarean section the mother is treated on a postoperative ward for at least two hours. Eight intensive care nurses participated in the study.

RESULT

The analysis yields the theme 'The challenges of caring for infants on a postoperative unit' covering the following categories; collision between the intensive care nurse and midwife, responsibility versus knowledge and organisational issues. The study concluded that improved routines and increased continuity between involved clinics could improve care. There is also a need for education for staff involved in caesarean section regarding the benefits of early skin-to-skin care between the mother and her infant.

Patient Perception of Acute Pain Management: Data from Three Tertiary Care Hospitals

Introduction. The primary objectives of this study were to assess patients' description of their acute pain intensity; patients' attitude towards their pain management during hospitalization; and their overall satisfaction with pain treatment. Methodology. A cross-sectional questionnaire-based study was conducted between October 2014 and March 2015 in three medical centers in Lebanon. All participants' responses were reported using descriptive statistics. The association between categorical variables was evaluated using Pearson χ² test or Fisher's exact test where the expected cell count was < 5. Results. A total of 119 women on the maternity services and 177 patients on the orthopedic services were surveyed. Around 50% of obstetric and 37% of orthopedic patients reported pain to be severe at its highest intensity. In maternity and orthopedic patients, respectively, unfavorable practices included pain not being assessed prior to pain medication administration (19.3% and 30.5%), having to wait for ≥30 minutes before getting the pain medication (14.2% and 11.3%), and pain score not being documented on medical chart (95% and 93.2%). Surprisingly, 94.1% of the maternity and 89.2% of orthopedic patients were satisfied to strongly satisfied with their pain management. Conclusion. Pre- and postoperative pain remain a prevalent problem that requires a consensus and joint efforts for improvement.

Randomized controlled trial of abdominal binders for postoperative pain, distress, and blood loss after cesarean delivery

OBJECTIVE

To assess the effect of using abdominal binders on pain, distress, and postpartum hemorrhage after cesarean delivery.

METHODS

The present prospective randomized controlled trial enrolled patients undergoing non-emergency cesarean deliveries in Gonbad-e Kavus, Golestan Province, Iran, between January 22 and October 23, 2015. Patients were randomized in a 1:1 ratio by blocks of four or six to a control group or to use an abdominal binder after delivery; all patients received routine care. The primary outcomes were visual analog scale-assessed pain, symptom distress scale (SDS)-assessed distress, and hemoglobin and hematocrit levels. Participants and researchers were masked to treatment assignments until after cesarean delivery, and data analysis was unmasked; intention-to-treat analyses were performed.

RESULTS

There were 89 patients enrolled in each group, with no differences in baseline pain scores, SDS scores, and hemoglobin and hematocrit levels between the groups (all P>0.05). Pain and SDS scores were lower in the binder group at all post-baseline time points compared with the control group (all P<0.001). Hemoglobin and hematocrit levels were higher among patients who received binders 36 hours after baseline (both P<0.001). There was one patient who experienced hemorrhage in the binders group and one patient requested removal of their binder.

CONCLUSION

Patients who received abdominal binders reported less pain, lower SDS scores, and higher hemoglobin and hematocrit levels following cesarean delivery.

Fixed time interval compared with on-demand oral analgesia protocols for post-caesarean pain: a randomised controlled trial

OBJECTIVES

To compare the efficacy, safety and satisfaction from two modes of oral analgesia administration for the treatment of post-caesarean pain in the first 48 h following surgery: on-demand versus fixed time interval administration.

DESIGN

Open label parallel-group, randomised-controlled trial from February to December 2013.

SETTING

University-affiliated hospital in Israel.

POPULATION

Two-hundred women who underwent caesarean delivery with regional anaesthesia.

METHODS

Patients were randomly assigned to receive predetermined combinations of tramadol, paracetamol and diclofenac either following patient demand or at predetermined 6-h intervals for the first 48 h. If the patient requested additional analgesia, Percocet (oxycodone and paracetamol) was given as a rescue treatment.

MAIN OUTCOME MEASURES

Pain intensity and satisfaction were self-evaluated with visual analogue scale of 0 (no pain/least satisfaction) to 10 (worst pain/highest satisfaction). Breastfeeding, need for supplemental formula, and maternal and neonatal adverse effects were also evaluated.

RESULTS

The 'fixed time interval' group, compared with the 'on-demand' group, had lower mean pain score (2.8 ± 0.84 versus 4.1 ± 0.48, respectively; P < 0.0001), higher satisfaction rate (9.1 ± 1.2 versus 8.3 ± 1.5, respectively; P < 0.0001), more breastfeeds (23.7 ± 6.5 versus 19.2 ± 6.2, respectively; P < 0.0001) and less use of supplemental formulas (8.2 ± 5.2 versus 11.9 ± 6.5, respectively; P < 0.0001). The number of times that drugs were given was slightly higher in the 'fixed time interval' group without an increase in maternal adverse effects, which were mild. No adverse effects were reported for the neonates.

CONCLUSION

Administration of oral analgesia in fixed time intervals is superior to drug administration following patient demand without increasing maternal or neonatal adverse outcomes.

TWEETABLE ABSTRACT

Oral analgesia in fixed time intervals is superior to analgesia following demand.

Efficacy of a single 40-mg intravenous dose of parecoxib for postoperative pain control after elective cesarean delivery: A double-blind randomized placebo-controlled trial

AIM

The aim of this study was to determine the efficacy of a single 40-mg intravenous (i.v.) dose of parecoxib as an adjunctive analgesia to intrathecal morphine after elective cesarean delivery (CD).

METHODS

A total of 82 low-risk term pregnant women who were scheduled for elective CD during the June 2014-June 2015 study period were enrolled. Two hours after surgery, subjects were randomly assigned to receive either i.v. injection of 2 mL (40 mg) parecoxib (study group; n = 41) or 2 mL normal saline solution (control group; n = 41). Patient randomization into groups was determined by the hospital's central computer system. Outcome measurements included total postoperative supplemental meperidine consumption, recorded pain score by numeric pain rating scale at 6, 12, 18, and 24 h, postoperatively, and patient satisfaction.

RESULTS

Patient characteristics and pregnancy outcomes were comparable between groups. Total postoperative meperidine consumption was not significantly different between groups (12.7 ± 18.8 mg vs 8.3 ± 16.7 mg; P > 0.05). Compared with control, the study group was significantly less likely to experience moderate to severe postoperative pain (score ≥ 4) at 6 h (0% vs 21.9%; P = 0.002). Study group patients reported higher satisfaction than control group patients (median score: 8 vs 6; P < 0.01). No patients in either group reported adverse effects from their assigned intervention.

CONCLUSION

Parecoxib did not demonstrate effectiveness in reducing patient requirement for supplementary meperidine after CD. However, administration of a single 40-mg dose of i.v. parecoxib after elective CD demonstrated effectiveness in reducing pain scores, with a resulting increase in patient satisfaction.

Interventions for women who have a caesarean birth to increase uptake and duration of breastfeeding: A systematic review

Rates of breastfeeding uptake are lower after a caesarean birth than vaginal birth, despite caesarean rates increasing globally over the past 30 years, and many high-income countries reporting overall caesarean rates of above 25%. A number of factors are likely to be associated with women's infant feeding decisions following a caesarean birth such as limited postoperative mobility, postoperative pain, and ongoing management of medical complications that may have triggered the need for a caesarean birth. The aim of this systematic review was to evaluate evidence of interventions on the initiation and duration of any and exclusive breastfeeding among women who had a planned or unplanned caesarean birth. Seven studies, presenting quantitative and qualitative evidence, published in the English language from January 1994 to February 2016 were included. A limited number of interventions were identified relevant to women who had had a caesarean birth. These included immediate or early skin-to-skin contact, parent education, the provision of sidecar bassinets when rooming-in, and use of breast pumps. Only one study, an intervention that included parent education and targeted breastfeeding support, increased initiation and continuation of breastfeeding, but due to methodological limitations, findings should be considered with caution. There is a need to better understand the impact of caesarean birth on maternal physiological, psychological, and physical recovery, the physiology of lactation and breastfeeding and infant feeding behaviors if effective interventions are to be implemented.

Opinions of women towards cesarean delivery and priority issues of care in the postpartum period

This study was conducted, in order to determine the opinions of women who had a cesarean delivery and the problems that they faced in the postpartum period. This descriptive study was conducted with 337 women who delivered babies by cesarean section. The data were collected using a semi-structured questionnaire. The results of the study showed that 53.4% of women underwent cesarean delivery for the first time, and 83.1% said that it was the obstetrician's decision to have a cesarean delivery. More than half of the women (61.1%) had a negative experience with cesarean delivery due to postpartum pain (44.7%) and inability to care for their infant (35.9%). The most common problems associated with cesarean delivery were postpartum pain (96.1%), back pain (68.2%), problems passing gas (62.0%), bleeding (56.1%), breastfeeding problems (49.6%) and limitation of movement (43.6%) respectively. Understanding the the opinions and problems of women towards cesarean delivery assists healthcare professionals in identifying better ways to provide appropriate care and support.

Physiological mechanisms, behavioral and psychological factors influencing the transfer of milk from mothers to their young

This article is part of a Special Issue "Parental Care".Producing milk to support the growth of their young is a central element of maternal care in mammals. In spite of the facts that ecological constraints influence nursing frequency, length of time until weaning and the composition of milk, there is considerable similarity in the anatomy and physiology of milk production and delivery across mammalian species. Here we provide an overview of cross species variation in nursing patterns and milk composition as well as the mechanisms underlying mammary gland development, milk production and letdown. Not all women breastfeed their infants, thus in later sections we review studies of factors that facilitate or impede the initiation and duration of breastfeeding. The results of these investigations suggest that the decisions to initiate and maintain breastfeeding are influenced by an array of personal, social and biological factors. Finally, studies comparing the development of breastfed and formula fed infants as well as those investigating associations between breastfeeding, maternal health and mother/infant interaction are reviewed. Leading health agencies including the World Health Organization and CDC advocate breastfeeding for at least the first 6months postpartum. To achieve these rates will require not only institutional support but also a focus on individual mother/infant dyads and their experience.

Benson Relaxation Technique in Reducing Pain Intensity in Women After Cesarean Section

Background:

Post-cesarean section women experience pain due to operative trauma. Pain sensation can be reduced by pain management. Pharmacological and non-pharmacological treatments can be used. The Benson Relaxation Technique is a non-pharmacological way suitable to reduce pain, but there are limited studies on its post-cesarean section use.

Objectives:

This study aimed to determine the effect of Benson Relaxation Technique in reducing pain intensity in women after cesarean section.

Patients and Methods:

This was a quasi-experiment study with pre and post-test design. A prospective, not blind, randomized assign, two groups parallel study was conducted in Cibabat hospital Cimahi as intervention group (IG) and Sartika Asih hospital as control group (CG). Post cesarean section women with quota sampling who met the inclusion criteria were consecutively assigned to either experimental (n = 30) or control group (n = 30). Women in the experimental group received the Benson relaxation technique and those in the control group received regular care from the health workers. The outcome pain severity was measured by visual analogue scale. Those instruments were applied before and after intervention.

Results:

The mean of pain score before intervention at CG was 4.43 cm. It was decreased to 4.40 cm (1 min), 4.27 cm (12 h), 4.10 cm (24 h), 4.00 cm (36 h), 3.93 cm (48 h), 3.83 cm (60 h), 3.67 cm (72 h) and 3.51 cm (84 h). Meanwhile, the IG was 4.97 cm. It was decreased to 4.90 cm (1 min), 4.23 cm (12 h), 3.57 cm (24 h), 3.03 cm (36 h), 2.77 cm (48 h), 2.73 cm (60 h), 2.67 cm (72 h) and 2.63 cm (84 h). The study found a significant difference comparing pain intensity before and after the intervention in CG and IG (P = 0.001), but pain reduced in IG more than CG.

Conclusions:

The Benson relaxation could reduce pain intensity in women after cesarean section.

Existential security is a necessary condition for continued breastfeeding despite severe initial difficulties: a lifeworld hermeneutical study

Background

The majority of new mothers in Sweden initiate breastfeeding and many experience initial difficulties. This experience is an important cause of early breastfeeding cessation. To increase understanding, there is a need to explore the lived experiences of the decision to continue or cease breastfeeding. The aim of this study is therefore to explain and understand how this decision is influenced by the meaning of severe initial difficulties.

Methods

A lifeworld hermeneutical approach was used for the study. The study was conducted in Sweden with eight mothers who experienced severe difficulties with initial breastfeeding. All except one were interviewed on two different occasions resulting in fifteen interviews. The interviews were conducted between 2010 and 2013.

Results

Mothers who experience severe difficulties with initial breastfeeding feel both overtaken and violated not only by their own infants and their own bodies but also by their anger, expectations, loneliness and care from health professionals. These feelings of being overtaken and invaded provoke an existential crisis and place mothers at a turning point in which these feelings are compared and put in relation to one another in the negotiation of the decision to continue or cease breastfeeding. This decision thus depends on the possibility of feeling secure with the breastfeeding relationship. If insecurity dominates, this can, in severe cases, create a feeling of fear of breastfeeding that is so great that there is no alternative but to stop breastfeeding.

Conclusions

Existential security in the breastfeeding relationship seems to be an underlying factor for confidence and therefore a necessary condition for continued breastfeeding when having severe initial breastfeeding difficulties. Unresolved feelings of insecurity may be a serious barrier to further breastfeeding that can result in a fear of breastfeeding. Such fear can force the mother to cease breastfeeding. This study highlights how women are situated in a complex cultural and biological context of breastfeeding that has existential consequences for them. An existential crisis forces mothers into a turning point for the breastfeeding decision. In the existential crisis, mothers’ responsibility for the mother-infant relationship guides continuing or ceasing breastfeeding.

Effect of high-volume systematic local infiltration analgesia in Caesarean section: a randomised, placebo-controlled trial

BACKGROUND

Pain after Caesarean section is often treated with opioids with a risk of side effects. Wound infiltration with local anaesthetics is effective and has few side effects, but volume vs. dose concentration has not been examined.

METHODS

Ninety patients scheduled for elective Caesarean section included in a randomised, double-blinded, placebo-controlled trial receiving infiltration with 50 ml ropivacaine 0.5% or 125 ml ropivacaine 0.2% or 50 ml 0.9% saline (placebo) during surgery. Surgery was performed under lumbar spinal anaesthesia. Primary endpoint was post-operative pain. Secondary endpoints were rescue analgesic, post-operative nausea and vomiting, time spent in the postanesthesia care unit (PACU) and time to first mobilisation.

RESULTS

No difference in pain response between groups, but time until maximum pain score was prolonged in the ropivacaine 0.5% group compared with the placebo group (P = 0.0493). The administration of ketobemidone at 24 h post-operatively in the ropivacaine 0.5% group was reduced compared with the placebo group (P = 0.020), and between the ropivacaine 0.2% group and the ropivacaine 0.5% group (P = 0.044). No significant differences between groups were found concerning time spent in the PACU, to first mobilisation or in number of women with nausea/vomiting (P ≥ 0.05). No complications related to ropivacaine were observed.

CONCLUSIONS

Systematic infiltration with a high concentration, low volume compared with low concentration, high volume showed no significant effect on post-operative pain intensity. However, a statistically significant, but clinically limited opioid sparing effect was demonstrated compared with placebo in the high concentration, low volume group.

Oral oxycodone for pain after caesarean section: A randomized comparison with nurse-administered IV morphine in a pragmatic study

Background and aims The present randomized open label parallel group study was conducted to evaluate if an oral oxycodone (OXY) regimen can be at least equally effective and as safe for postoperative analgesia after caesarean section (CS) as a standard of care program using nurse-administered intravenous morphine (IVM), followed by oral codeine. Methods Eighty women (40 + 40) were scheduled for elective CS under spinal anaesthesia. All patients received postoperative multimodal analgesic therapy, including ibuprofen and paracetamol. The OXY group got standardized extended release and short acting oral treatment (and in a few cases intravenous OXY) as needed and the other group received current standard of care, IVM as needed for 24 h, followed by codeine. Opioid treatment lasted maximum five days. Outcome measures were pain intensity (numerical rating scale, NRS), opioid requirements, duration of administering opioids and safety for mother and newborn. All opioids in the study were expressed in OXY equivalents, using a conversion table. As the bioavailability of each opioid has a certain extent of interindividual bioavailability this conversion represents an approximation. The possible influence of opioids on the newborns was evaluated by the Neurological Adaptive Capacity Score at birth and at 24 and 48 h. Results During the first 24 h, there were no differences between treatments in opioid requirements or mean pain intensity at rest but pain intensity when asking for rescue medication was lower in the OXY than in the IVM group (mean ± SD; 5.41 ± 6.42 vs. 6.42 ± 1.61; p = 0.027). Provoked pain (uterus palpation) during the first 6h was also less in the OXY group (3.26 ± 2.13 vs. 4.60 ± 2.10; p = 0.007). During the 25-48 h period postoperatively, patients on OXY reported significantly lower pain intensity at rest (2.9 ± 1.9 vs. 3.8 ± 1.8; p = 0.039) and consumed less opioids (OXY equivalents; mg) (31.5 ± 9.6 vs. 38.2 ± 38.2; p = 0.001) than those on IVM/codeine. The total amount of opioids 0-5 days postoperatively was significantly lower in the OXY than in the IVM/codeine group (108.7 ± 37.6 vs. 138.2 ± 45.1; p = 0.002). Duration of administering opioids was significantly shorter in the OXY group. Time to first spontaneous bowel movement was shorter in the OXY group compared with the IVM/codeine group. No serious adverse events were recorded in the mothers but the total number of common opioid adverse effects was higher among women on IVM/codeine than among those receiving OXY (15 vs. 3; p = 0.007). No adverse outcomes in the newborns related to treatment were observed in either group. Conclusions In a multimodal protocol for postoperative analgesia after CS better pain control and lower opioid intake was observed in patients receiving oral OXY as compared to those on IVM/codeine. No safety risks for mother and child were identified with either protocol. Implications Our findings support the view that use of oral OXY is a simple, effective and time saving treatment for postoperative pain after CS.

Breastfeeding and pelvic girdle pain: a follow-up study of 10,603 women 18 months after delivery

OBJECTIVE

To study the associations of patterns and duration of breastfeeding with the persistence of pelvic girdle pain 18 months after delivery.

DESIGN

Longitudinal population study.

SETTING

Norway, for the period 1999-2011.

POPULATION

A follow-up of 10 603 women with singleton deliveries in the Norwegian Mother and Child Cohort Study who reported pelvic girdle pain at 0-3 months postpartum.

METHODS

Data were obtained by four self-administered questionnaires and linked to the Medical Birth Registry of Norway.

MAIN OUTCOME MEASURE

Pelvic girdle pain, defined as combined anterior and bilateral posterior pelvic pain, 18 months after delivery.

RESULTS

Eighteen months after delivery, 7.8% of respondents (829/10,603) reported pelvic girdle pain. Breastfeeding patterns at 5 months after delivery were not associated with persistence of pelvic girdle pain. The proportion of women with pelvic girdle pain 18 months after delivery increased as the duration of breastfeeding decreased (test for trend, P < 0.001). The estimated associations attenuated after adjustment for educational level, smoking status, and body mass index, but remained statistically significant for the association between 0 and 2 months of breastfeeding and persistent pelvic girdle pain (adjusted odds ratio 1.34; 95% confidence interval 1.03-1.75). The association of short breastfeeding duration with persistent pelvic girdle pain was only present in women with body mass index ≥25 kg/m(2) .

CONCLUSIONS

Breastfeeding was associated with a small beneficial effect on the recovery process of pelvic girdle pain in women with a body mass index ≥25 kg/m(2) . Among women with pelvic girdle pain, breastfeeding should be encouraged in accordance with the existing child-feeding recommendations.

Non-invasive fetal ECG analysis

Despite the important advances achieved in the field of adult electrocardiography signal processing, the analysis of the non-invasive fetal electrocardiogram (NI-FECG) remains a challenge. Currently no gold standard database exists which provides labelled FECG QRS complexes (and other morphological parameters), and publications rely either on proprietary databases or a very limited set of data recorded from few (or more often, just one) individuals.The PhysioNet/Computing in Cardiology Challenge 2013 enables to tackle some of these limitations by releasing a set of NI-FECG data publicly to the scientific community in order to evaluate signal processing techniques for NI-FECG extraction. The Challenge aim was to encourage development of accurate algorithms for locating QRS complexes and estimating the QT interval in non-invasive FECG signals. Using carefully reviewed reference QRS annotations and QT intervals as a gold standard, based on simultaneous direct FECG when possible, the Challenge was designed to measure and compare the performance of participants' algorithms objectively. Multiple challenge events were designed to test basic FHR estimation accuracy, as well as accuracy in measurement of inter-beat (RR) and QT intervals needed as a basis for derivation of other FECG features.This editorial reviews the background issues, the design of the Challenge, the key achievements, and the follow-up research generated as a result of the Challenge, published in the concurrent special issue of Physiological Measurement.

Maternal accounts of their breast-feeding intent and early challenges after caesarean childbirth

BACKGROUND

breast-feeding outcomes are often worse after caesarean section compared to vaginal childbirth.

OBJECTIVES

this study characterises mothers' breast-feeding intentions and their infant feeding experiences after caesarean childbirth.

METHODS

data are from 115 mothers on a postnatal unit in Northeast England during February 2006-March 2009. Interviews were conducted an average of 1.5 days (range 1-6 days) after the women underwent unscheduled or scheduled caesarean.

RESULTS

thematic analysis of the data suggested was mostly considered the 'right thing to do,' preferable, natural, and 'supposedly healthier,' but tiring and painful. Advantages of supplementation involved more satiated infants, feeding ease, and longer sleep bouts. The need for 'thinking about yourself' was part of caesarean recovery. Infrequent feeding was concerning but also enabled maternal rest. Other breast-feeding obstacles were maternal mobility limitations, positioning difficulties, and frustration at the need for assistance. Participants were confused about nocturnal infant wakings, leading many to determine that they had insufficient milk. Mothers were surprised that sub-clinically poor infant condition was common following caesarean section. Some breast-feeding difficulty stemmed from 'mucus' expulsion that had to occur before the infants could be 'interested' in feeding. Women who cited motivations for breast feeding that included benefit to themselves were more likely to exclusively breast feed on the postnatal unit after their caesareans than those who reported infant-only motivations.

CONCLUSIONS

for the majority of mothers, breast feeding after a caesarean is affected by interrelated and compounding difficulties. Provision of more relational breast-feeding information may enable families to better anticipate early feeding experiences after caesarean section childbirth.
