Exposure to General Anesthesia for Cesarean Delivery and Odds of Severe Postpartum Depression Requiring Hospitalization

The role of anesthesiologists in postpartum depression: current perspectives and future directions

Postpartum depression is a common complication of childbirth that can seriously affect women, infants, and families. In 2020, the National Health Commission of the People's Republic of China mandated depression and anxiety screenings during pregnancy and postpartum visits to ensure timely medical intervention and referrals to appropriate behavioral health resources. Anesthesiologists are indispensable members in obstetric practice. Optimal peripartum pain control can reduce stress response; promote breastfeeding; and lower maternal anxiety and depression. Recently, the discovery of the rapid and sustained antidepressant properties of ketamine and emerging evidence supporting the effectiveness of anesthetic drugs in the treatment of depressive disorders have positioned anesthesiologists on a new frontier for treating neuropsychiatric disorders. This review aimed to explore the impact of labor epidural analgesia, obstetric anesthesia, and anesthetic drugs on postpartum depression while discussing the emerging role of anesthesiologists in its prevention and treatment based on recent evidence.

Anesthetic and obstetric predictors of general anesthesia in urgent or emergent Cesarean delivery: a retrospective case-control study

PURPOSE

While regional anesthesia (RA) is considered preferable to general anesthesia (GA) for Cesarean delivery (CD), certain situations necessitate GA. This study reviewed the practice patterns around the use of GA for CD to identify modifiable predictors of GA with the goal of reducing GA rates.

METHODS

This was a retrospective, case-control study. Patients undergoing urgent/emergent CD over a 3-year period were identified, from which 102 patients undergoing GA and 102 patients undergoing RA were randomly selected. The data included patient characteristics, obstetrical indications for CD, type/indication of anesthetic, characteristics of airway management (GA group)/neuraxial anesthesia (RA group), and neonatal outcomes.

RESULTS

Abnormal fetal heart rate (aFHR) was the most common obstetrical indication for urgent/emergent CD amongst the cases (39%) and controls (39%). GA administration was most commonly due to "limited time due to maternal/fetal compromise" (56%), followed by "maternal contraindication to RA" (25%) and "inadequate RA" (17%). The most frequent modifiable anesthetic indication for GA was inadequate neuraxial anesthesia (17%). Anesthetic and obstetric predictors for GA included ASA classification [OR 0.11 (0.06-0.21)], emergency code activation [OR 13.55 (1.73-106.40)], failure to progress [OR 0.15 ((0.06-0.36)], labor in a patient scheduled for CD [OR 0.16 (0.05-0.57)], pregnancy-related illness [OR 8.63 (1.06-70.38)], cord/fetal prolapse [14.85(1.90-115.94)], and gestational age (OR 0.86 (0.81-0.92)).

CONCLUSION

Abnormal fetal heart rate, specifically bradycardia, was the most common obstetrical indication of GA for urgent/emergent CD, while inadequate neuraxial anesthesia was the most  modifiable anesthetic indication. Our data suggest aFHR and cord/fetal prolapse as potentially modifiable risk factors for GA in certain situations.

Incidence of psychiatric disorders after total knee or hip arthroplasty by anesthesia type: A nationwide cohort study

BACKGROUND

Evidence is lacking of an association between anesthetic choice and the risk of psychiatric disorders. Therefore, this study aimed to examine the impact of regional anesthesia (R/A) versus general anesthesia (G/A) on the occurrence of psychiatric disorders in patients undergoing total knee arthroplasty (TKA) or total hip arthroplasty (THA).

METHODS

Data for this population-based cohort study were sourced from the National Health Insurance Service of South Korea. The study included adult patients who underwent TKA or THA between January 1, 2016, and December 31, 2021. The endpoint was the diagnosis of postoperative psychiatric disorders within 1 year postoperative.

RESULTS

This study included 411,967 patients who underwent THA or TKA. Among them, 290,476 (70.5 %) underwent THA or TKA under R/A (R/A group), while 121,491 (29.5 %) underwent THA or TKA under G/A (G/A group). In multivariate logistic regression, the R/A group had an 8 % lower incidence of postoperative psychiatric disorders (odds ratio [OR], 0.92; 95 % confidence interval [CI], 0.90-0.94; P < 0.001) than the G/A group. Specifically, a lower incidence of postoperative psychiatric disorder for depression (OR, 0.89; 95 % CI, 0.86-0.92; P < 0.001), bipolar disorder (OR, 0.88; 95 % CI, 0.83-0.94; P < 0.001), anxiety disorder (OR, 0.95; 95 % CI, 0.92-0.98; P = 0.001), and insomnia disorder (OR, 0.95; 95 % CI, 0.80-1.11; P = 0.496) was observed in the R/A versus G/A group.

CONCLUSIONS

Among these South Korean patients who underwent TKA or THA, the R/A group had a lower incidence of postoperative psychiatric disorders than the G/A group.

Association of General Anesthesia for Cesarean Delivery with Postpartum Depression and Suicidality

BACKGROUND

Compared to neuraxial anesthesia, general anesthesia (GA) for cesarean delivery is associated with an increased risk of postpartum depression (PPD) requiring hospitalization. However, obstetric complications occurring during childbirth (eg, stillbirth) are associated with both increased use of GA and increased risk of PPD, and may account for the reported association between GA and PPD. This study assessed the association of GA for cesarean delivery with PPD requiring hospitalization, outpatient visit, or emergency department (ED) visit, accounting for obstetric complications.

METHODS

This retrospective cohort study included women who underwent a cesarean delivery in New York State between January 2009 and December 2017. Women were followed for 1 year after discharge for readmission, outpatient visit, or ED visit. The primary outcome was PPD requiring readmission, outpatient visit, or ED visit. The 2 secondary outcomes were (1) PPD requiring readmission, and (2) suicidality. Obstetric complications included severe maternal morbidity, blood transfusion, postpartum hemorrhage, preterm birth, and stillbirth. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of PPD, PPD requiring readmission, and suicidality associated with GA were estimated using the propensity score matching and the overlap propensity score weighting methods.

RESULTS

Of the 325,840 women included, 19,513 received GA (6.0%; 95% CI, 5.9-6.1). Complications occurred in 43,432 women (13.3%) and the GA rate for these women was 9.7% (95% CI, 9.4-10.0). The incidence rate of PPD was 12.8 per 1000 person-years, with 24.5% requiring hospital readmission, and was higher when an obstetric complication occurred (17.1 per 1000 person-years). After matching, the incidence rate of PPD was 15.5 per 1000 person-years for women who received neuraxial anesthesia and 17.5 per 1000 person-years for women who received GA, yielding an aHR of 1.12 (95% CI, 0.97-1.30). Use of GA was associated with a 38% increased risk of PPD requiring hospitalization (aHR: 1.38; 95% CI, 1.07-1.77) and with a 45% increased risk of suicidality (aHR 1.45; 95% CI, 1.02-2.05). Results were consistent when using the overlap propensity score weighting.

CONCLUSIONS

Use of GA for cesarean delivery is independently associated with a significantly increased risk of PPD requiring hospitalization and suicidality. It underscores the need to avoid using GA whenever appropriate and to address the potential mental health issues of patients after GA use, specifically by screening for PPD and providing referrals to accessible mental health providers as needed.

National survey on clinical practice in obstetric analgesia in Spain

INTRODUCTION

A national survey was conducted among maternity hospitals nationwide to understand the variability in clinical practice for obstetric analgesia and to reach a consensus on optimal care in the future in Spain.

MATERIALS AND METHODS

Spanish experts in obstetric anesthesiology designed a survey on the practice of obstetric analgesia during childbirth, following a Delphi process. The survey was sent to 195 Spanish maternity hospitals between April and September 2022 using Google Forms. A descriptive study of the results was performed.

RESULTS

Responses were obtained from 108 centres (55.4%), of which 88 (83.8%) were public hospitals. The most commonly used technique was epidural analgesia in 97 (92.4%) centres. Nine (8.6%) centres used the combined spinal-epidural (CSE) technique, 5 (4.8%) used spinal analgesia, and 3 (2.9%) used dural puncture epidural (DPE) analgesia. The most commonly used local anaesthetic was levobupivacaine 0.1-0.25% in 82 (78.1%) centres. Fentanyl or sufentanil were added to the local anaesthetic in 96 (91.4%) centres. Epidural maintenance was performed with continuous epidural infusion (CEI) + patient-controlled epidural analgesia (PCEA) or programmed intermittent epidural bolus (PIEB) + PCEA in 64 (60.9%) and 33 (30.5%) centres, respectively. Fifteen (14.3%) centres lacked alternative techniques to epidural analgesia and 25 (23.8%) did not follow obstetric analgesia protocols.

CONCLUSION

Despite the variability in clinical practice for obstetric analgesia in Spain, the vast majority of centres follow recommendations in this field. There is room for improvement, which should be considered a fundamental strategy for progressing towards excellence.

Anesthesia for cesarean delivery and subsequent depression: A nationwide retrospective cohort study

BACKGROUND

Postpartum depression is a major psychiatric disorder associated with maternal suicide and child developmental disturbances. In this study, we aimed to investigate whether general anesthesia for cesarean delivery is associated with a higher rate of new-onset depression after delivery than neuraxial anesthesia.

METHODS

This is a nationwide retrospective cohort study using data retrieved from the National Health Insurance Research Database between 2014 and 2018. Women who had cesarean delivery under general or neuraxial anesthesia were enrolled. After 1:4 propensity score matching, there were 4544 and 18,176 women under the general and neuraxial anesthesia groups, respectively. The primary outcome was new-onset depression diagnosed after delivery in a time-to-event analysis setting.

RESULTS

After propensity-score matching, the rate of new-onset depression diagnosed within 1 year was 1.10 % (50/4488) and 0.86 % (157/18176) after cesarean delivery under general and neuraxial anesthesia, respectively. For depression diagnosed within 90 days of delivery, significant difference between the two groups was noted (0.51 % vs. 0.30 %, P = 0.031). In the time-to-event analysis with Cox regression model, women who delivered under general anesthesia were associated with significantly higher risk of postpartum depression within 90 days (Hazard ratio [HR], 1.71; 95 % CI, 1.05-2.79) compared with those under neuraxial anesthesia.

LIMITATIONS

The observational design only allows asserting association, rather than establishing causality between exposure and outcomes.

CONCLUSIONS

Women who underwent cesarean delivery under general anesthesia had a higher risk of subsequent depression within 90 days than those under neuraxial anesthesia. Early screening for depressive disorders might facilitate timely management.

Issues and Solutions in Psychiatric Clinical Trial with Case Studies

The coronavirus disease-2019 pandemic resulted in a major increase in depression and anxiety disorders worldwide, which increased the demand for mental health services. However, clinical interventions for treating mental disorders are currently insufficient to meet this growing demand. There is an urgent need to conduct scientific and standardized clinical research that are consistent with the features of mental disorders in order to deliver more effective and safer therapies in the clinic. Our study aimed to expose the challenges, complexities of study design, ethical issues, sample selection, and efficacy evaluation in clinical research for mental disorders. The reliance on subjective symptom presentation and rating scales for diagnosing mental diseases was discovered, emphasizing the lack of clear biological standards, which hampers the construction of rigorous research criteria. We underlined the possibility of psychotherapy in efficacy evaluation alongside medication treatment, proposing for a multidisciplinary approach comprising psychiatrists, neuroscientists, and statisticians. To comprehend mental disorders progression, we recommend the development of artificial intelligence integrated evaluation tools, the use of precise biomarkers, and the strengthening of longitudinal designs. In addition, we advocate for international collaboration to diversity samples and increase the dependability of findings, with the goal of improving clinical research quality in mental disorders through sample representativeness, accurate medical history gathering, and adherence to ethical principles.

The Effect of Spacer Treatment of Infected Hip and Knee Arthroplasties on Patients' Mental Health: A Narrative Review of the Literature

BACKGROUND

The gold standard treatment for periprosthetic joint infections is the two-stage revision that includes the spacer placement before definitive reimplantation. The management of PJI affects patients' joint function and, subsequently, their mental health. Even though significant advances have been achieved, little to no attention has been paid to the psychological implications. So, based on standardized patient-reported outcome measures (PROMs), this study aimed to clarify the effect of spacer treatment of infected hip and knee arthroplasties on patients' mental health.

METHODS

We performed research on the literature on PJIs in the English language using the MEDLINE database with the search strings "spacer" OR "spacers" AND "hip" OR "knee" AND "SF-12" OR "SF-36" OR "EQ-5" OR "mental" OR "depression" OR "anxiety." The reference lists of selected articles were also hand-searched for any additional articles.

RESULTS

A total of 973 published papers were extracted, and 9 papers were finally included. A total of 384 patients who underwent spacer placement for PJI were identified. Of these 384 patients, 54% were female. The mean age ranged from 62 to 78.2 years. Of the11 papers identified for this review, 4 analyzed only hip spacers, including 119 patients; 4 only knee spacers, evaluating 153 patients; while a single study included 112 patients for both joints.

CONCLUSIONS

Patients with the spacer are living in a state of mental upset, albeit better than the preoperative state. Clinical improvement with the review is not assured. The alteration of mental state turns out not to be transient for all the patients.

Transversus abdominis plane block improves postoperative recovery following cesarean delivery under general anesthesia: A propensity score matched retrospective cohort study

OBJECTIVE

To evaluate the effects of transversus abdominis plane (TAP) block on postoperative recovery 24 h after cesarean delivery under general anesthesia.

METHODS

A propensity-score-matched, retrospective cohort study was used. A total of 173 pregnancies resulting in elective cesarean delivery under general anesthesia between March 2021 and March 2022 were analyzed retrospectively. Patients receiving TAP block were compared with those receiving only intravenous analgesia. The Quality of Recovery 15 (QoR-15) score, assessed 24 h postoperatively using a 15-item questionnaire, was the primary outcome. Secondary outcomes included time to first ambulation, time to first flatus postoperatively, ability to tolerate ambulation, visual analog scale (VAS) score, hospitalization cost, and postoperative nausea and/or vomiting.

RESULTS

The total QoR-15 score 24 h postoperatively in the TAP group was significantly higher than in the Control group (P < 0.001). Patients in the TAP group had higher Bruggemann comfort scale scores (P < 0.001), could better tolerate early postoperative ambulation (P < 0.001), and had shorter time to first ambulation (P < 0.001) and flatus (P < 0.001). Correlation analysis demonstrated an inverse relationship between the cumulative VAS pain scores, time to first postoperative ambulation, time to first flatus, and total QoR-15 score 24 h postoperatively.

CONCLUSIONS

Following cesarean delivery under general anesthesia, TAP block combined with intravenous analgesia can improve postoperative recovery and shorten the time to postoperative ambulation and recovery of intestinal function.

Racial and Ethnic Disparities in Receipt of General Anesthesia for Cesarean Delivery

Importance

General anesthesia for cesarean delivery is associated with increased maternal morbidity, and Black and Hispanic pregnant patients have higher rates of general anesthesia use compared with their non-Hispanic White counterparts. It is unknown whether risk factors and indications for general anesthesia differ among patients of differing race and ethnicity.

Objective

To evaluate differences in general anesthesia use for cesarean delivery and the indication for the general anesthetic by race and ethnicity.

Design, Setting, and Participants

In this retrospective, cross-sectional, single-center study, electronic medical records for all 35 117 patients who underwent cesarean delivery at Northwestern Medicine's Prentice Women's Hospital from January 1, 2007, to March 2, 2018, were queried for maternal demographics, clinical characteristics, obstetric and anesthetic data, the indication for cesarean delivery, and the indication for general anesthesia when used. Data analysis occurred in August 2023.

Exposure

Cesarean delivery.

Main Outcomes and Measures

The rate of general anesthesia for cesarean delivery by race and ethnicity.

Results

Of the 35 117 patients (median age, 33 years [IQR, 30-36 years]) who underwent cesarean delivery, 1147 (3.3%) received general anesthesia; the rates of general anesthesia were 2.5% for Asian patients (61 of 2422), 5.0% for Black patients (194 of 3895), 3.7% for Hispanic patients (197 of 5305), 2.8% for non-Hispanic White patients (542 of 19 479), and 3.8% (153 of 4016) for all other groups (including those who declined to provide race and ethnicity information) (P < .001). A total of 19 933 pregnant patients (56.8%) were in labor at the time of their cesarean delivery. Of those, 16 363 (82.1%) had neuraxial labor analgesia in situ. Among those who had an epidural catheter in situ, there were no racial or ethnic differences in the rates of general anesthesia use vs neuraxial analgesia use (Asian patients, 34 of 503 [6.8%] vs 1289 of 15 860 [8.1%]; Black patients, 78 of 503 [15.5%] vs 1925 of 15 860 [12.1%]; Hispanic patients, 80 of 503 [15.9%] vs 2415 of 15 860 [15.2%]; non-Hispanic White patients, 255 of 503 [50.7%] vs 8285 of 15 860 [52.2%]; and patients of other race or ethnicity, 56 of 503 [11.1%] vs 1946 of 15 860 [12.3%]; P = .16). Indications for cesarean delivery and for general anesthesia were not different when stratified by race and ethnicity.

Conclusions and Relevance

Racial disparities in rates of general anesthesia continue to exist; however, this study suggests that, for laboring patients who had labor epidural catheters in situ, no disparity by race or ethnicity existed. Future studies should address whether disparities in care that occur prior to neuraxial catheter placement are associated with higher rates of general anesthesia among patients from ethnic and racial minority groups.

Investigating Racial and Ethnic Disparities in Maternal Care at the System Level Using Patient Safety Incident Reports

BACKGROUND

Maternal mortality in the United States is high, and women and birthing people of color experience higher rates of mortality and severe maternal morbidity (SMM). More than half of maternal deaths and cases of SMM are considered preventable. The research presented here investigated systems issues contributing to adverse outcomes and racial/ethnic disparities in maternal care using patient safety incident reports.

METHODS

The authors reviewed incidents reported in the labor and delivery unit (L&D) and the antepartum and postpartum unit (A&P) of a large academic hospital in 2019 and 2020. Deliveries associated with a reported incident were described by race/ethnicity, age group, method of delivery, and several other process variables. Differences across racial/ethnic group were statistically evaluated.

RESULTS

Almost two thirds (64.8%) of the 528 reports analyzed were reported in L&D, and 35.2% were reported in A&P. Non-Hispanic white (NHW) patients accounted for 43.9% of reported incidents, non-Hispanic Black (NHB) patients accounted for 43.2%, Hispanic patients accounted for 8.9%, and patients categorized as "other" accounted for 4.0%. NHB patients were disproportionally represented in the incident reports, as they accounted for only 36.5% of the underlying birthing population. The odds ratio (OR) demonstrated a higher risk of a reported adverse incident for NHB patients; however, adjustment for cesarean section attenuated the association (OR 1.25, 95% confidence interval 1.01-1.54).

CONCLUSION

Greater integration of patient safety and health equity efforts in hospitals are needed to promptly identify and alleviate racial and ethnic disparities in maternal health outcomes. Although additional systems analysis is necessary, the authors offer recommendations to support safer, more equitable maternal care.

The "30-minute rule" for expedited delivery: fact or fiction?

Initially developed from hospital feasibility data from the 1980s, the "30-minute rule" has perpetuated the belief that the decision-to-incision time in an emergency cesarean delivery should be <30 minutes to preserve favorable neonatal outcomes. Through a review of the history, available data on delivery timing and associated outcomes, and consideration of feasibility across several hospital systems, the use and applicability of this "rule" are explored, and its reconsideration is called for. Moreover, we have advocated for balanced consideration of maternal safety with rapidity of delivery, encouraged process-based approaches, and proposed standardization of terminology regarding delivery urgency. Furthermore, a standardized 4-tier classification system for delivery urgency, from class I, for a perceived threat to maternal or fetal life, to class IV, a scheduled delivery, and a call for further research with a standardized structure to facilitate comparison have been proposed.

High-impact papers in the field of anesthesiology: a 10-year cross-sectional study

PURPOSE

This study was performed to evaluate trends in and provide future direction for anesthesiology education, research, and clinical practice.

METHODS

We collected high-impact papers, ranking in the top 10% in the field of anesthesiology and published from 2011 to 2020, by the InCites tool based on the Web of Science Core Collection. We analyzed the trends, locations, distribution of subject categories, research organizations, collaborative networks, and subject terms of these papers.

RESULTS

A total of 4,685 high-impact papers were included for analysis. The number of high-impact papers increased from 462 in 2011 to 520 in 2020. The paper with the highest value of category normalized citation impact (115.95) was published in Anesthesia and Analgesia in 2018. High-impact papers were mainly distributed in the subject categories of "Anesthesiology," "Clinical Neurology," "Neurosciences," and "Medicine General Internal." They were primarily cited in "Anesthesiology," "Clinical Neurology," "Neurosciences," "Medicine General Internal," and "Surgery." Most of these high-impact papers came from the USA, UK, Canada, Germany, and Australia. The most productive institutions were the League of European Research Universities, Harvard University, University of Toronto, University of London, University of California System, and University Health Network Toronto. Research collaboration circles have been formed in the USA, UK, and Canada. Subject-term analysis indicated postoperative analgesia, chronic pain, and perioperative complications were high-interest topics, and COVID-19 became a new hot topic in 2020.

CONCLUSIONS

The current study provides a historical view of high-impact papers in anesthesiology in the past ten years. High-impact papers were mostly from the USA. Postoperative analgesia, chronic pain, and perioperative complications have been hot topics, and COVID-19 became a new topic in 2020. These findings provide references for education, research, and clinical practice in the field of anesthesiology.

Association of General Anesthesia and Neuraxial Anesthesia in Caesarean Section with Maternal Postpartum Depression: A Retrospective Nationwide Population-Based Cohort Study

Although cesarean section (CS) has become a common method of child delivery in recent decades, the choice between general anesthesia (GA) and neuraxial anesthesia (NA) for CS must be carefully considered. Depending on the type of anesthesia used in CS, a major outcome observed is the occurrence of postpartum depression (PPD). This study investigated the association between PPD risk and the anesthesia method used in CS by using data from three linked nationwide databases in Taiwan, namely, the National Health Insurance Research Database, the National Birth Reporting Database, and the National Death Index Database. After propensity score matching by baseline depressive disorders, maternal demographics, status at delivery, infant’s health, maternal diseases during pregnancy, and age of partner, we included women who had natural births (n = 15,706), cesarean sections with GA (n = 15,706), and cesarean sections with NA (n = 15,706). A conditional logistic regression was used to estimate the odds ratios and 95% confidence intervals (CIs) of PPDs, including depression, sleep disorder, and medication with hypnotics or antidepressants, under anesthesia during CS. The prevalence rates of combined PPDs were 26.66%, 43.87%, and 36.30% in natural births, CS with GA, and CS with NA, respectively. In particular, the proportions of postpartum use of hypnotic drugs or antidepressants were 21.70%, 39.77%, and 31.84%, which were significantly different. The aORs (95% CIs) were 2.15 (2.05–2.25) for the included depressive disorders, 1.10 (1.00–1.21) for depression, 1.03 (0.96–1.11) for sleep disorder, and 2.38 (2.27–2.50) for medication with hypnotics or antidepressants in CS with GA compared with natural births. Women who underwent CS with GA had a significantly higher risk of depressive disorders and a higher need for antidepressants for sleep problems than those who underwent CS with NA. The risks of PPD were significantly associated with the anesthesia method, especially GA. Our results can assist physicians in carefully considering the appropriate anesthesia method for CS delivery, particularly with regard to postpartum drug abuse and drug safety.

Use of Labor Neuraxial Analgesia for Vaginal Delivery and Severe Maternal Morbidity

Importance

Addressing severe maternal morbidity (SMM) is a public health priority in the US. Use of labor neuraxial analgesia for vaginal delivery is suggested to reduce the risk of postpartum hemorrhage (PPH), the leading cause of preventable severe maternal morbidity.

Objective

To assess the association between the use of labor neuraxial analgesia for vaginal delivery and SMM.

Design, Setting, and Participants

In this population-based cross-sectional study, women aged 15 to 49 years undergoing their first vaginal delivery were included. Data were taken from hospital discharge records from New York between January 2010 and December 2017. Data were analyzed from November 2020 to November 2021.

Exposures

Neuraxial analgesia (ie, epidural or combined spinal-epidural) vs no neuraxial analgesia.

Main Outcomes and Measures

The primary outcome was SMM, as defined by the US Centers for Disease Control and Prevention, and the secondary outcome was PPH. Adjusted odds ratios (aORs) and 95% CIs of SMM associated with neuraxial analgesia were estimated using the inverse propensity score-weighting method and stratified according to race and ethnicity (non-Hispanic White vs racial and ethnic minority women, including non-Hispanic Asian or Pacific Islander, non-Hispanic Black, Hispanic, and other race and ethnicity) and to the comorbidity index for obstetric patients (low-risk vs high-risk women). The proportion of the association of neuraxial analgesia with the risk of SMM mediated through PPH was estimated using mediation analysis.

Results

Of 575 524 included women, the mean (SD) age was 28 (6) years, and 46 065 (8.0%) were non-Hispanic Asian or Pacific Islander, 88 577 (15.4%) were non-Hispanic Black, 104 866 (18.2%) were Hispanic, 258 276 (44.9%) were non-Hispanic White, and 74 534 (13.0%) were other race and ethnicity. A total of 400 346 women (69.6%) were in the low-risk group and 175 178 (30.4%) in the high-risk group, and 272 921 women (47.4%) received neuraxial analgesia. SMM occurred in 7712 women (1.3%), of which 2748 (35.6%) had PPH. Before weighting, the incidence of SMM was 1.3% (3486 of 272 291) with neuraxial analgesia compared with 1.4% (4226 of 302 603) without neuraxial analgesia (risk difference, -0.12 per 100; 95% CI, -0.17 to -0.07). After weighting, the aOR of SMM associated with neuraxial analgesia was 0.86 (95% CI, 0.82-0.90). Decreased risk of SMM associated with neuraxial analgesia was similar between non-Hispanic White women and racial and ethnic minority women and between low-risk and high-risk women. More than one-fifth (21%; 95% CI, 14-28) of the observed association of neuraxial analgesia with the risk of SMM was mediated through the decreased risk of PPH.

Conclusions and Relevance

Findings from this study suggest that use of neuraxial analgesia for vaginal delivery is associated with a 14% decrease in the risk of SMM. Increasing access to and utilization of labor neuraxial analgesia may contribute to improving maternal health outcomes.

Suicide and Maternal Mortality

PURPOSE OF REVIEW

Suicide is a leading cause of death in the perinatal period (pregnancy and 1 year postpartum). We review recent findings on prevalence, risk factors, outcomes, and prevention and intervention for suicide during pregnancy and the first year postpartum.

RECENT FINDINGS

Standardization of definitions and ascertainment of maternal deaths have improved identification of perinatal deaths by suicide and risk factors for perinatal suicide. Reports of a protective effect of pregnancy and postpartum on suicide risk may be inflated. Clinicians must be vigilant for risk of suicide among their perinatal patients, especially those with mental health diagnoses or prior suicide attempts. Pregnancy and the year postpartum are a time of increased access to healthcare for many, offering many opportunities to identify and intervene for suicide risk. Universal screening for suicide as part of assessment of depression and anxiety along with improved access to mental health treatments can reduce risk of perinatal suicide.

General or regional anaesthesia for postpartum haemorrhage-A national population-based cohort study

BACKGROUND

Anaesthesia is required to assist the treatment of postpartum haemorrhage (PPH) when manual removal of the placenta or emptying of the uterine cavity is required. The choice between general or regional anaesthesia may depend upon factors such as existing epidural, airway, hypovolaemia, and tradition.

METHODS

Data from a randomized controlled trial of PPH (FIB-PPH) was used to reveal differences between delivery centres. In addition, national data of 5,601 PPH procedures requiring anaesthesia during 2010-2015 was collected from the Danish Medical Birth Registry, the National Danish Patient Registry, and the Danish Anaesthesia Database. The aim is to describe the variation in choice of anaesthesia for treatment of PPH.

RESULTS

Data from the randomized trial showed large differences in practice between centres not explained by physiological factors. Using national Danish registry data, we show that large delivery centres as compared to small centres prefer regional anaesthesia for PPH procedures in opposed to general anaesthesia. Sevoflurane was used despite it causing uterine relaxation. The use of general anaesthesia was associated with younger parturients, larger blood loss, and larger Body-Mass Index. Aspiration was recorded in one case (0.02%). In the postoperative care-unit general anaesthesia was associated with a shorter stay, but also higher pain score at admission.

CONCLUSION

Practice varies immensely between delivery centres with large centres preferring regional anaesthesia. Difference in practice might be explained by level of experience, here large centres might be more confident using regional anaesthesia. Knowledge is being extrapolated from literature on caesarean sections. Future studies should address the optimal choice of anaesthesia for PPH procedures.

Perioperative Outcomes in COVID-19 Obstetric Patients Undergoing Spinal Anesthesia for Cesarean Section: A Prospective Observational Study

Coronavirus disease 2019 (COVID-19) adds more challenges to the perioperative management of parturients. The aim of this study is to examine perioperative adverse events and hemodynamic stability among COVID-19 positive parturients undergoing spinal anesthesia. This prospective observational investigation was conducted at a tertiary teaching hospital in Jordan between January and June 2021, during which 31 COVID-19 positive parturients were identified. Each COVID-19 positive parturient was matched with a COVID-19 negative parturient who received anesthesia under similar operating conditions as a control group. Of the 31 COVID-19 patients, 22 (71%) were otherwise medically free, 8 (25.8%) were emergency cesarean sections. The sensory level of spinal block after 10 min was T8 (T6–T10) among COVID-19 positive group, compared to T4 (T4–T6) among control group (p = 0.001). There were no significant differences in heart rate, SBP, DBP, and MAP intraoperatively (p > 0.05). Twelve (36.4%) neonates born to COVID-19 positive patients were admitted to NICU, compared to four (11.8%) among control group (p = 0.018). There was no statistically significant difference in postoperative complications. In conclusion, spinal anesthesia is considered a safe anesthetic technique in COVID-19 parturients, and therefore it is the anesthetic method of choice for cesarean deliveries among COVID-19 patients.

Perinatal depression

PURPOSE OF REVIEW

Perinatal depression is a common and debilitating complication of pregnancy and childbirth. Recent studies have elucidated relationships between acute birth events on depression risk, and novel treatments for postpartum depression have been discovered and approved. This article reviews current understandings about birth events on depression, new screening standards, and novel treatments for postpartum depression.

RECENT FINDINGS

Pain, analgesia, and depression are complex traits that are inter-related during and after pregnancy. Certain individuals may benefit more than others from addressing pain and suffering around childbirth. Exposures to general anesthesia or postdural puncture headache are associated with postpartum depression symptoms, although a causal relationship is unlikely. Brexanolone, ketamine and its related compounds, and nonpharmacologic options offer new or alternative therapies for depression, although safety information for some of these treatments in pregnancy and lactation are needed. Maternal health bundles call for close attention to perinatal mental health screening with validated instruments, and for timely treatment referrals in the 'fourth trimester'.

SUMMARY

Clinical monitoring and timely treatment of depression in the perinatal and postpartum periods is critical for maternal postpartum health and recovery. Perinatal specialists and researchers should continue to focus on tailored treatments specific to this special population.

The Current Role of General Anesthesia for Cesarean Delivery

PURPOSE OF THE REVIEW

The use of general anesthesia for cesarean delivery has declined in the last decades due to the widespread utilization of neuraxial techniques and the understanding that neuraxial anesthesia can be provided even in urgent circumstances. In fact, the role of general anesthesia for cesarean delivery has been revisited, because despite recent devices facilitating endotracheal intubation and clinical algorithms, guiding anesthesiologists facing challenging scenarios, risks, and complications of general anesthesia at the time of delivery for both mother and neonate(s) remain significant. In this review, we will discuss clinical scenarios and risk factors associated with general anesthesia for cesarean delivery and address reasons why anesthesiologists should apply strategies to minimize its use.

RECENT FINDINGS

Unnecessary general anesthesia for cesarean delivery is associated with maternal complications, including serious anesthesia-related complications, surgical site infection, and venous thromboembolic events. Racial and socioeconomic disparities and low-resource settings are major contributing factors in the use of general anesthesia for cesarean delivery, with both maternal and perinatal mortality increasing when general anesthesia is provided. In addition, more significant maternal pain and higher rates of postpartum depression requiring hospitalization are associated with general anesthesia for cesarean delivery.

SUMMARY

Rates of general anesthesia for cesarean delivery have overall decreased, and while general anesthesia no longer is a contributing factor to anesthesia-related maternal deaths, further opportunities to reduce its use should be emphasized. Raising awareness in identifying situations and patients at risk to help avoid unnecessary general anesthesia remains crucial.

Unplanned Cesarean delivery is associated with risk for postpartum depressive symptoms in the immediate postpartum period

PURPOSE

Postpartum depression (PPD) is a common pregnancy complication. The association between cesarean delivery (CD) and PPD has shown conflicting results in prior studies, although emergent CD appears to be a clear risk factor. Establishing PPD risk is critical and may, however, be related to the unplanned nature of the CD, rather than the surgery itself. Our objective was to determine whether women who underwent unplanned CD were more likely than those with vaginal delivery to have higher depressive symptoms and thus screen positive for PPD risk in the immediate postpartum period.

MATERIALS AND METHODS

This cohort study was conducted at a community medical center using data for deliveries between 8/2015-1/2016. Women were screened in the hospital for depressive symptoms (PPD risk) using the Edinburgh Postnatal Depression Scale (EPDS) within 4 days post-delivery. Logistic regression, adjusting for maternal race/ethnicity and parity, was performed to evaluate the association between delivery route (vaginal vs planned vs unplanned CD) and PPD risk (EPDS ≥ 10).

RESULTS

A total of 2094 women had complete data for analysis. Overall, 44 women (2.1%) screened positive for PPD risk. Logistic regression results showed that unplanned CD was significantly associated with PPD risk (OR = 2.28, 95% CI 1.13-4.57, p = .022), after adjusting for parity and race/ethnicity. Planned CD was not associated with PPD risk.

CONCLUSION

Unplanned CD may be an independent risk factor for PPD risk in the immediate postpartum period. This finding might explain why some previous studies have demonstrated different results with regards to risk of CD where the unplanned nature of the delivery was not accounted for.
