Investigating the association between labour epidural analgesia and postpartum depression: A prospective cohort study

Factors influencing the choice of lumbar epidural analgesia and its association with postpartum depression risk

BACKGROUND

The use of lumbar epidural analgesia (LEA) during childbirth varies significantly among women. Factors influencing a woman's choice of LEA and its possible effects on postpartum depression (PPD) remain underexplored.

OBJECTIVES

To investigate factors influencing the choice of LEA among women with intended vaginal deliveries. A secondary objective was to explore the association between LEA use and PPD.

STUDY DESIGN

A longitudinal cohort study.

SETTING

Uppsala University Hospital, Sweden, 2010 to 2019.

POPULATION

Women with an intended vaginal delivery.

EXCLUSIONS

Twins, elective caesarean section, induction of labour.

METHODS

Data were collected by web-based self-completed questionnaires at gestational weeks 17, 32 and at 6 weeks and 6 months postpartum. The exposures were sociodemographic, resilience-related, medical and obstetric characteristics of all participants from the BASIC (Biology, Affect, Stress, Imaging and Cognition) study. Information on the use of LEA was retrieved from medical records. PPD was assessed using either the Edinburgh Postnatal Depression Scale, or the Depression Self-Rating Scale, and/or the Mini-International Neuropsychiatric Interview at 6 to 8 weeks and 6 months postpartum. Bayesian models were applied to investigate the associations of multivariate factors with the choice for LEA, and the association between the use of LEA and PPD.

RESULTS

Among 4436 participants, 38% opted for LEA, while 62% did not. LEA users were younger, primiparous, reported higher rates of intimate partner violence (IPV) and had lower resilience. The adjusted model revealed primiparity, previous caesarean section, IPV, pregnancy length at least 280 days and fear of childbirth as independent predictors of LEA use. While LEA use was associated with higher odds of PPD in the crude regression model, it was no longer statistically significant after adjusting for possible confounders and mediators.

CONCLUSION

Social and psychological vulnerabilities influence a woman's decision to opt for LEA during childbirth. LEA was not associated with PPD in adjusted models.

TRIAL REGISTRATION

This is a longitudinal study which was not registered back in 2010.

Protocol for prognosticating PPD using EEG changes during labor pain by uterine contractions: a prospective cohort study in the first stage of labor

BACKGROUND

Lack of motivation and behavioral abnormalities are the hallmarks of postpartum depression (PPD). Severe uterine contractions during labor are pain triggers for psychiatric disorders, including PPD in women during the puerperium. Creating biomarkers to monitor PPD may help in its early detection and treatment. It has been suggested that uterine contraction-induced labor pain plays a role in the emergence of this syndrome. Therefore, abnormal electroencephalography (EEG) patterns during the first stage of labor may provide useful information. Here, we propose that aberrant EEG patterns caused by painful uterine contractions may be predictive markers for PPD.

METHODS

This study is a single-centre prospective cohort planned for 331 parturients for vaginal delivery in the maternity ward of Zhujiang Hospital from 2022 to 2023. At baseline, online or paper-based questionnaires, including the Edinburgh Postnatal Depression Scale (EPDS) and demographic data, will be collected when the parturient is admitted to labor. EEG, electrocardiography (ECG) and electrohysterography (EHG) signals will be monitored and recorded during the first stage of labor in the ward. Follow-up will be taken at the postpartum timepoints of day 3, day 42, and 3, 6 and 12 months, respectively. Power spectral density and functional connections will be quantified. The connections between PPD severity and EEG measurements as a function of time will be assessed using linear mixed-effects models. Maternal age, parity, and whether oxytocin is used during labor, all have an impact on the incidence of PPD, hence a stratified analysis will be carried out.

DISCUSSION

We expect EEG changes caused by painful uterine contractions in the first labor may predict early PPD. The results from this study may act as a predictor for the development of PPD which may enhance long-term quality of life for the parturient and her offspring.

Association between epidural analgesia and postpartum psychiatric disorders: A meta-analysis

Aim

Women during the postpartum period are at risk for psychiatric disorders such as postpartum depression (PPD), post-traumatic stress disorder (PTSD), and anxiety. It is controversial whether labour epidural analgesia have a protective role on PPD, PTSD, and anxiety or not. This study is a meta-analysis of previously published observational studies to investigate the association between epidural analgesia and PPD, PTSD, and anxiety.

Methods

We searched Cochran Library, PubMed, ProQuest, EMBASE, Scopus, Web of Science, PsycINFO, and MEDLINE from inception until December 2022. The outcome measures were positive screen of PPD, PTSD, and anxiety among women who received labour epidural analgesia. The Newcastle-Ottawa Scale was used to assess the quality of the observational studies. Statistical analysis was performed using Stata 17.0 software. The mean differences or odds ratios were pooled based on random effect.

Results

We included 31 studies (12,064 women) in the review. The meta-analysis of PPD studies reported mean (standard deviation) showed no significant association between epidural analgesia and PPD (Mean Difference = 0.01; 95% Confidence Interval = -0.14 to 0.16; p-value = 0.88). The meta-analysis of PPD studies reported percentage showed no statistically significant difference in terms of the chance of depression between the exposed and non-exposed groups (Log Odds Ratio = -0.61; 95% CI = -1.48 to 0.26; p-value = 0.17). The meta-analysis of PPD studies reported OR showed indicate a lower chance of depression in the epidural group compared to the non-epidural group (Effect size = 1.01; 95% CI = 0.64 to 1.38; P-value = 0.00). In the case of PTSD, due to the heterogeneity of the tools and the methodology of the studies, it was impossible to reach a definitive conclusion and measure the studies in a meta-analysis. The meta-analysis of anxiety studies showed that no significant association between epidural analgesia and anxiety (MD = -1.36; 95% CI = -3.38 to 1.14; p-value = 0.29).

Conclusion

Based on the meta-analysis of observational studies, epidural analgesia for labour pain relief has no protective effect on postpartum psychiatric disorders.

Association of inpatient postpartum quality of recovery with postpartum depression: A prospective observational study

STUDY OBJECTIVE

To explore the relationship between Obstetric Quality of Recovery survey (ObsQoR-10-Heb) and Edinburgh postnatal depression scale (EPDS) measured 6 weeks after delivery, adjusted for potential confounding factors.

DESIGN

Prospective, longitudinal cohort study.

SETTING

Large postpartum department, 13,000 annual deliveries, quaternary medical center in Israel.

PATIENTS

Women ≥18 years old, gestational age ≥ 37 weeks after term delivery (spontaneous vaginal, operative vaginal, planned, and unplanned cesarean delivery), with non-anomalous neonates not requiring special support after delivery or at the time of recruitment. Written informed consent was provided. Women unable to read or understand Hebrew were excluded.

INTERVENTIONS

No interventions were done.

MEASUREMENTS

We investigated the relationship between inpatient postpartum recovery and positive postpartum depression (PPD) screening at 6 weeks postpartum. Enrolled women completed the validated Hebrew version of ObsQoR-10 survey (ObsQoR-10-Heb; scored between 0 and 100 with 0 and 100 representing worst and best possible recovery) from 24 to 48 h after delivery, and the Edinburgh Postnatal Depression Scale (EPDS) at 6- and 12 weeks postpartum. We assessed the univariate association between ObsQoR-10-Heb; patient factors; obstetric factors; and positive PPD screening at 6 weeks postpartum. Potential confounders were adjusted in a multiple logistic regression model.

MAIN RESULTS

Inpatient ObsQoR-10-Heb has been completed by 325 postpartum women; 270 (83.1%) and 253 (77.9%) completed the 6- and 12 weeks EPDS respectively. Lower ObsQoR-10-Heb (aOR 0.95 (95% CI 0.92, 0.98); p = 0.001); depression or anxiety before delivery (aOR 4.53 (95% CI 1.88, 10.90); p = 0.001); and hospital readmission (aOR 9.08 (95% CI 1.23, 67.14); p = 0.031) were associated with positive screening for postpartum depression at 6 weeks.

CONCLUSIONS

Our study demonstrates that worse inpatient postpartum recovery is an independent risk factor for positive PPD screening at 6 weeks postpartum. Other risk factors found in our study were maternal hospital readmission and a previous history of anxiety or depression.

Association between the use of epidural analgesia during labour and incidence of postpartum depression

INTRODUCTION

Postpartum depression is a significant episode of depression beginning after giving birth. The prevalence of postpartum depression is approximately 20% in Jeddah, Saudi Arabia. Epidural analgesia is the gold standard for labour pain management. Conflicting results exist regarding the association between postpartum depression and epidural analgesia use during labour. Accordingly, this study assessed the association between epidural analgesia use and postpartum depression incidence.

METHODS

A prospective observational study of 170 mothers was conducted, with surveys administered after labour and at six weeks postpartum. Surveys included the following: mothers' demographics, obstetric history, postpartum depression (Edinburgh Postnatal Depression Scale), and pain severity (Visual Analogue Scale).

RESULTS

In the final analysis, 91 patients were enrolled. Epidural analgesia was administered to 48.4% of mothers during labour. Nearly two-thirds of mothers learned about EA via sources including family members and social media. However, more than half reported worries regarding epidural analgesia. Edinburgh Postnatal Depression Scale scores showed that 38 mothers (41.8%) likely had depressive symptoms within two days following delivery. Further, 35 (38.5%) met criteria for postpartum depression at six weeks postpartum. For both groups regardless use of analgesia, the mean Visual Analogue Scale score at two days postpartum was 4.16 ± 2.13. Data revealed no correlation between epidural analgesia use and Edinburgh Postnatal Depression Scale within two days and at six weeks postpartum. Multiple regression analysis showed Edinburgh Postnatal Depression Scale scores correlated with Visual Analogue Scale scores but not epidural analgesia use at 1-2 days postpartum.

CONCLUSION

This study showed that depressive symptoms resolved in three percent of participants. This suggests that institutions should increase postpartum depression awareness during the antenatal period and implement effective post-delivery screening systems for postpartum depression.

Maternal Depression during Pregnancy and Postpartum Period among the Association of Southeast Asian Nations (ASEAN) Countries: A Scoping Review

Identification of mothers with depression is important because untreated perinatal depression can have both short- and long-term consequences for the mother, the child, and the family. This review attempts to identify the prevalence of antenatal and postnatal depression (AD and PD, respectively) of mothers among the ASEAN member countries. A literature review was conducted using PubMed, Scopus, and the Asian Citation Index. The reviews covered publications in peer-reviewed journals written in the English language between January 2010 and December 2020. Of the 280 articles identified, a total of 37 peer-reviewed articles conducted in 8 out of 11 ASEAN member countries were included. The Edinburgh Postnatal Depression Scale (EPDS) was the most common instrument used to identify depression. This study showed the number of studies reporting the prevalence of AD was 18 in five countries. For PD, 24 studies in eight countries were included. The prevalence of AD ranged from 4.9% to 46.8%, and that of PD ranged from 4.4% to 57.7%. This first review among ASEAN countries showed very few studies conducted in lower-middle-income and substantial heterogeneity in prevalence among studies reviewed. Further research should be conducted to estimate the prevalence using a large representative sample with a validated assessment tool among the ASEAN countries.

Investigating the association between maternal childbirth intention, labor epidural analgesia, and postpartum depression: A prospective cohort study

BACKGROUND

Postpartum depression (PPD) is a general depressive episode after childbirth. Studies have shown that unmatched analgesic intention increases the risk of PPD, but the use of labor epidural analgesia (LEA) during childbirth can reduce this risk. We aimed to investigate the association between maternal childbirth intention, LEA, and PPD and risk factors that may be related to PPD.

METHODS

A total of 590 mothers were included in this prospective cohort study. Demographic, prenatal, intrapartum and postpartum data were recorded. We investigated the association between childbirth intention, LEA and PPD and assessed the interactions between two factors. Logistic regression analysis was used to screen variables that might be associated with the occurrence of PPD.

RESULTS

Overall, 130 of 451 women completing the study at 3 months had PPD (28.8 %). We did not find an association between unmatched childbirth intention, use of LEA and PPD (adjustOR = 0.684 CI 0.335-1.396, p = 0.296; adjustOR = 0.892, CI 0.508-1.565, p = 0.690). Chronic pain affecting daily life, prenatal EPDS, SAS, SSRS score, family accompaniment during labor, and 1-day numerical rating scale (NRS) score were significantly associated with PPD (p < 0.05).

LIMITATIONS

In the 3-month follow-up, we only recorded the EPDS score, not the pain score, and did not evaluate the association between postpartum chronic pain and PPD.

CONCLUSIONS

The association between maternal childbirth intention, LEA and PPD was not significant. Chronic pain affecting daily life, prenatal EPDS, SAS, SSRS score, family accompaniment during labor, and 1-day NRS score were significantly related to the occurrence of PPD (p < 0.05).

Neuraxial analgesia during labor and postpartum depression: Systematic review and meta-analysis

BACKGROUND

Severe pain has been linked to depression, which raises the question of whether neuraxial analgesia during childbirth is associated with a reduced risk of postpartum depression. This association has been explored, but previous studies did not control or analyze relevant confounders. We conducted a systematic review and meta-analysis to determine the association between neuraxial analgesia and postpartum depression.

METHODS

A systematic review was conducted using PubMed, Embase, and the Cochrane Central Register of Controlled Trials. Studies that tested the effect of neuraxial analgesia during labor on depression or depressive symptoms in the first year postpartum were included. Relevant articles were extracted independently by 2 authors.

RESULTS

In total, 14 studies (86,231 women) were included. The association between neuraxial analgesia and the long-term incidence of postpartum depression after childbirth was the risk ratio = 0.75, 95% confidence interval (CI): 0.56-1.00, P = .05; I2 = 79%, P < .00001. There was a significant association (pooled risk ratio = 0.55, 95% CI: 0.34-0.90, P = .02; I2 = 55%, P = .06) between neuraxial analgesia and the incidence of postpartum depression in the first week after delivery. The subgroup analysis showed a trend suggesting that in Asian populations, those who received neuraxial analgesia had lower postpartum depression rates than those who received non-neuraxial analgesia (risk ratio = 0.57, 95% CI: 0.38-0.86; P = .008; I2 = 82%) at ≥4 weeks after delivery.

CONCLUSION

Neuraxial analgesia may be beneficial for the short-term and long-term mental effects of parturient women, especially for short term after delivery. High-quality studies addressing the role of neuraxial analgesia during labor and its impact on postpartum depression remain necessary.

Obstetric anesthesia clinic childbirth course combined with labor epidural analgesia is associated with a decreased risk of postpartum depression : a prospective cohort study

BACKGROUND

Postpartum depression (PPD) is a serious complication commonly seen in postnatal women. In this paper, an investigation was conducted to see if obstetric anesthesia clinic childbirth course combined with labor epidural analgesia (LEA) was associated with a decreased risk of PPD.

METHODS

Six hundred fifty-five nulliparous women were enrolled in this prospective cohort study. The parturients were divided into 4 groups, with Group C being the control group, Group AC received the obstetric anesthesia clinic childbirth course only, Group LEA received LEA only, and Group AC + LEA received both the obstetric anesthesia clinic childbirth course and LEA. Maternal and neonatal variables in the perinatal period were recorded. PPD at 6 weeks was assessed using the Chinese version of the Edinburgh Postpartum Depression Scale (EPDS), where a score ≥ 10 is the threshold for PPD. Multivariate logistic regression analysis was performed to assess the association between obstetric anesthesia clinic childbirth course combined with LEA and postpartum depression.

RESULTS

A total of 124 maternities had EPDS ≥10 points, the incidence of PPD was 18.9%。The incidence of PPD and EPDS scores were significantly lower in Group AC + LEA than in Group C (12.1% vs 26.8%, P <  0.05; 6 (5, 7) vs 7 (5, 11), P <  0.05). Received an anesthesia clinic childbirth course combined with LEA was associated with a decreased risk of PPD (OR 0.273, 95% CI, 0.100-0.743, P = 0.013). Multivariate logistic regression analysis identified 5 other independent factors for PPD, including maternal SAS score in the delivery room, W-DEQ score in the delivery room, living in a confinement center, EPDS score at 1st week postpartum and perinatal care satisfaction .

CONCLUSIONS

Received an obstetrics anesthesia clinic childbirth course combined with LEA for nulliparous women with a single term cephalic pregnancy was associated with a decreased risk of PPD at 6 weeks.

Childbirth Pain, Labor Epidural Analgesia, and Postpartum Depression: Recent Evidence and Future Directions

Pregnancy and childbirth are major life events for women and their families, characterized by physical, psychological, and emotional changes that can trigger anxiety, depression, and mental disorders in susceptible individuals. Acute labor pain is an independent risk factor for persistent pain in the postpartum period and is associated with depressive disorders. Epidural analgesia is a well-established technique that has commonly been regarded as the gold standard in pain management during labor. Although the relationships between labor pain, labor epidural analgesia, and postpartum depression have been studied by many investigators, the results of these studies are conflicting. Some literature suggest that labor epidural analgesia is associated with a reduction in the incidence of postpartum depression; however, other studies have failed to demonstrate this association. Unmet analgesic needs expectations, unmet birth expectations, and/or the quality of social support during labor may contribute to postpartum depression. The limitations of the published studies included differential misclassification of study variables and residual confounding, variations in the diagnosis of depression, and incomplete history data. Thus, future studies should include information on sociodemographic and patient-level variables and assessments of pain during labor or in the postpartum period. Better management of labor pain should be provided to prevent long-term morbidity and improve maternal and neonatal outcomes. Anesthesiologists could collaboratively work with obstetricians and perinatal psychiatrists to ensure that hospitals prioritize screening and treatment for postpartum depression.

Unexpected changes in birth experiences during the COVID-19 pandemic: Implications for maternal mental health

PURPOSE

This study examined the rates of unexpected birth experiences due to the COVID-19 pandemic and its association with women's postpartum mental health symptoms (depression, generalized anxiety, and PTSD).

METHODS

Our cross-sectional analysis included postpartum women (N = 506) who reported on birth plan changes attributed to the COVID-19 pandemic through the PEACE (Perinatal Experiences and COVID-19 Effects) Study, an online survey that took place between May 2020 and May 2021. Covariates included sociodemographic variables, number of days since the pandemic, pre-pregnancy mental health history, and protective factors such as social support, distress tolerance, and resilience.

RESULTS

Prevalent COVID-19 pandemic changes in the birth experience included not having support people (e.g., partners and friends) permitted to participate in the baby's delivery (33.5%), reduced access to preferred medications before or after delivery (9.7%), unavailable health care providers for the baby's birth as planned (9.6%), and other changes (13.8%). The reduced access to medications was associated with those reporting higher levels of depressive (β = .10, p < .01) and PTSD symptoms (β = .07, p < .05). Separation from their baby for a long period after delivery (β = .10, p < .05) and other changes (β = .10, p < .01) were associated with higher levels of PTSD symptoms.

CONCLUSION

Unexpected changes to the birth experience due to the COVID-19 pandemic may have small but persistent effects on depressive and PTSD symptoms. Given increased vigilance and its association with subsequent PTSD, acknowledging any fear of viral contagion within the hospital setting but informing women the plans for ensuring safety may be preventive for later mental health symptomatology.

Association between neuraxial labor analgesia and postpartum depression: A meta-analysis

BACKGROUND

Labor and delivery complications, particularly pain, are important risk factors for postpartum depression (PPD). Neuraxial labor analgesia can effectively relieve labor pain; however, the association between neuraxial labor analgesia and PPD, if any, has not been established.

METHODS

PubMed, MEDLINE, EMBASE, ClinicalTrials.gov, and Cochrane Library were searched. The incidence of PPD was the primary outcome. The secondary outcome was the difference in postpartum Edinburgh Postpartum Depression Scale scores between the neuraxial labor analgesia and control groups. Subgroup analyses and post-hoc meta-regression were performed.

RESULTS

Nineteen studies with a total of 8758 parturients were identified. Neuraxial labor analgesia did not decrease PPD risk compared to the control group (OR = 0.84, 95% CI: 0.58-1.23); however, after being stratified by PPD prevalence, neuraxial labor analgesia decreased the risk for PPD in the high prevalence (>14%) subgroup (OR = 0.61, 95% CI: 0.39-0.94) and increased the risk for PPD in the low prevalence (<14%) subgroup (OR = 1.56, 95% CI: 1.16-2.10) compared to the control group. Meta-regression analysis showed that the association between neuraxial labor analgesia and PPD was influenced by PPD prevalence. There was no difference in the postpartum Edinburgh Postpartum Depression Scale scores between the neuraxial labor analgesia and control groups (WMD = -0.11, 95% CI: -0.56-0.34).

LIMITATION

Heterogeneity and a limited number of randomized controlled trials may bias the interpretation of the results.

CONCLUSION

Neuraxial labor analgesia had a protective effect when administered to parturients in the region with a high prevalence of PPD, but became a risk factor when administered to parturients in the region with a low prevalence of PPD.

Association of Childbirth Pain with Postnatal Depressive and Anxiety Disorders in Nulliparous Parturients: A Prospective Study

PURPOSE

There is limited knowledge on the relationship between postnatal depression and childbirth pain characteristics associated with childbirth. We investigated whether the characteristics of childbirth pain, as assessed by Short-form-McGill Pain Questionnaire-2 (SF-MPQ-2), were associated with postnatal anxiety and depressive disorders.

PATIENTS AND METHODS

Nulliparous parturients who received labor epidural analgesia (LEA) and delivered in our institution were invited to have a Mini-International Neuropsychiatric Interview (MINI) assessment following their 5-9 weeks post-delivery follow-up phone survey of a larger study. Parturients' demographics, pre-delivery questionnaires on pain and psychological vulnerabilities, LEA data, maternal and neonatal outcomes, postnatal follow-up survey on pain and psychological vulnerabilities, pain and breastfeeding were collected accordingly. The primary outcome was the binary variable (yes/no) of the presence of postnatal depression and/or anxiety disorders based on the post-delivery MINI assessment.

RESULTS

Among the 107 parturients who participated in the post-delivery MINI assessment, a total of 40 (42.5%) patients were found to have postnatal anxiety and depressive disorders. A greater pre-delivery SF-MPQ-2 neuropathic pain mean subscale score (adjusted odds ratio (OR) 1.32, 95% CI 1.00-1.73, p=0.0482) and greater post-delivery Edinburgh Postnatal Depression Scale (EPDS) at 5-9 weeks post-delivery (adjusted OR 1.30, 95% CI 1.13-1.50, p=0.0002) were independently associated with the presence of postnatal anxiety and/or depressive disorders (receiver operating characteristic (ROC) = 0.7489).

CONCLUSION

Patients with greater pre-delivery neuropathic pain and higher EPDS scores at 5-9 weeks post-delivery are more likely to have postnatal depression and/or anxiety disorders, suggesting possible associations between pain and psychological vulnerability in the development of postnatal mental disorders.

A systematic review of the association between postpartum depression and neuraxial labor analgesia

BACKGROUND

Postpartum depression (PPD) is the most common complication after childbirth, affecting 10-15% of women. It is associated with serious long-term consequences for the mother and family. Whether or not neuraxial labor analgesia mitigates the risk is uncertain and controversial. The purpose of this review was to summarize studies investigating the association between neuraxial labor analgesia and the incidence of PPD.

METHODS

A systematic literature search for randomized controlled trials and cohort studies reporting the incidence of PPD among parturients who received neuraxial analgesia compared with non-neuraxial or no analgesia. The primary outcome was the incidence of PPD between 5 and 12 weeks' postpartum. Depression was diagnosed using a cutoff score of ≥10 on the Edinburgh Postnatal Depression scale, a validated screening tool. The risk of bias of each study was evaluated, and odds ratios and 95% confidence intervals calculated from raw data or reported as adjusted odds ratios.

RESULTS

Eleven observational studies involving 5717 patients were included. Three studies had a critical risk, three a serious risk, and five a moderate risk of bias. Two studies reported significantly lower odds for PPD associated with neuraxial analgesia compared with non-neuraxial or no analgesia, whereas the odds ratios in the remaining nine studies were not significantly different.

CONCLUSIONS

Our systematic review did not find compelling evidence for an association between PPD and labor analgesia. Studies were heterogenous in nature and had a high risk of bias. Further research controlling for confounding factors is recommended to determine if a relationship exists.
