Relation between Epidural Analgesia and severe perineal laceration in childbearing women in Catalonia

Midwife-attended planned home births versus planned hospital births in Spain: Maternal and neonatal outcomes

BACKGROUND

The debate on the safety and outcomes of home versus hospital births highlights the need for evidence-based evaluations of these birthing settings, particularly in Catalonia where both options are available.

AIM

To compare sociodemographic characteristics and maternal and neonatal outcomes between low-risk women opting for home versus hospital births in Catalonia, Spain.

METHODS

This observational cross-sectional study analysed 3,463 low-risk births between 2016 and 2018, including 2,713 hospital and 750 home births. Researchers collected sociodemographic data, birthing processes, and outcomes, using statistical analysis to explore differences between the settings.

FINDINGS

Notable differences emerged: Women choosing home births typically had higher education levels and were predominantly Spanish. They were 3.43 times more likely to have a spontaneous birth and significantly less likely to undergo instrumental births than those in hospitals. Home births were associated with higher utilization of non-pharmacological analgesia and a more pronounced tendency to iniciate breastfeeding within the first hour post birth and stronger inclination towards breastfeeding. Hospital births, conversely, showed higher use of the lithotomy position and epidural analgesia. There were no significant differences in neonatal outcomes between the two groups.

CONCLUSIONS AND IMPLICATION FOR PRACTICE

Home births managed by midwives offered better obstetric and neonatal outcomes for low-risk women than hospital births. These results suggest home birth as a safe, viable option that promotes natural birthing processes and reduces medical interventions. The study supports the integration of midwife-led home birth into public health policies, affirming its benefits for maternal and neonatal health.

Is epidural analgesia an independent risk factor for OASIS? A population-based cohort study

INTRODUCTION

To evaluate whether epidural analgesia is an independent risk factor for OASIS.

METHODS

A population-based cohort study including all women who delivered by spontaneous vaginal delivery or by instrumental delivery beyond 24 weeks gestation was conducted. Deliveries occurred between 1988 and 2016 at a large university tertiary medical center. Women with multiple gestations and those lacking prenatal care were excluded from the analysis.

RESULTS

During the study period, 252,542 women delivered at the Soroka University Medical Center and met the inclusion criteria. Of these, 583 (0.23%) were diagnosed with OASIS. Women with OASIS were more likely to be younger, nulliparous, with suspected fetal macrosomia, had higher rates of labor induction and vacuum extraction delivery, higher rates of conceiving after infertility treatments, more advanced gestational age at delivery, higher mean birth weight, higher rates of post-partum hemorrhage and need for blood transfusions. Use of epidural analgesia during pregnancy was significantly high among the OASIS group. Rates of episiotomy were not significantly different between the groups. Using a multimodal logistic regression model, after controlling for vacuum delivery, large for gestational age, nulliparity, gestational age, ethnicity, maternal age, induction of labor, fertility treatments, non-reassuring fetal heart rate and non-progressive second stage of labor, epidural analgesia was found to be significantly associated with OASIS.

CONCLUSION

Epidural analgesia was found to be an independent risk factor for OASIS in our population.

Association of epidural analgesia during labor and early postpartum urinary incontinence among women delivered vaginally: a propensity score matched retrospective cohort study

BACKGROUND

Although epidural analgesia is considered the gold standard for pain relief during labor and is safe for maternity and fetus, the association between the epidural analgesia and pelvic floor disorders remains unclear. Thus we estimate the association between epidural analgesia and early postpartum urinary incontinence (UI).

METHODS

A propensity score-matched retrospective cohort study was conducted at a university-affiliated hospital in Shanghai, China. Primiparous women with term, singleton, and vaginal delivery between December 2020 and February 2022 were included. UI was self-reported by maternity at 42 to 60 days postpartum and was classified by International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Using logistic regression models, the associations between epidural analgesia and early postpartum UI were assessed.

RESULTS

Among 5190 participants, 3709 (71.5%) choose epidural anesthesia during labor. Analysis of the propensity-matched cohort (including 1447 maternal pairs) showed epidural anesthesia during labor was independently associated with UI in early postpartum period (aOR 1.50, 95% CI 1.24-1.81). This association was mainly contributed to stress UI (aOR 1.38, 95% CI 1.12-1.71) rather than urge UI (aOR 1.45, 95% CI 0.99-2.15) and mixed UI (aOR 1.52, 95% CI 0.95-2.45). Furthermore, we observed that the association between epidural anesthesia and UI was more pronounced among older women (≥ 35 y) and women with macrosomia (infant weight ≥ 4000 g), compared with their counterparts (both P for interaction < 0.01). After further analysis excluding the women with UI during pregnancy, the results remained largely consistent with the main analysis.

CONCLUSIONS

The findings support that epidural anesthesia was associated with SUI in the early postpartum period.

Risk factors associated with breakdown of perineal laceration repair after vaginal birth

Underlying infection, estimated blood loss >500 ml and operative delivery are independent risk factors for breakdown of perineal laceration repair after vaginal birth.

[Childbirth outcomes and perineal damage in women with natural childbirth in Korea: a retrospective chart review]

Purpose

This study aimed to determine the actual state of childbirth in Korean women with natural childbirth and the degree of damage to the perineum during childbirth.

Methods

This retrospective study analyzed the medical records of mothers who had natural childbirth at a hospital in Seoul, Korea in 2018. Data from 358 women with cephalic births at greater than 37 gestational weeks were analyzed. To determine natural childbirth characteristics and the degree of damage to the perineum, descriptive statistics were done. The difference in the degree of perineal injury according to obstetric characteristics was analyzed using independent t-test and one-way analysis of variance.

Results

The mean age was 33.18±3.68 years, and 49.2% were primiparas, while 39% gave birth with a doula. The degree of perineal damage differed by age (F=9.15, p<.001), parity (t=19.13, p<.001), number of births in multiparity (F=3.68, p=.027), previous vaginal delivery in multiparity (F=3.00, p=.032) and birthing posture (F=7.44, p<.001). Having received therapeutic procedures (t=-4.62, p<.001), specifically fluid administration (t=-2.72, p=.007), oxygen supply (t=--2.76, p=.006) and epidural anesthesia (t=-2.77, p=.006) were statistically significant for perineal damage. There were no differences, however, by gestational period, doula use, water room use in labor, baby head circumference, or birth weight.

Conclusion

Study findings suggest that support for older women, primiparas, and those who require therapeutic procedures may help to decrease the possibility of perineal damage during childbirth. As perineal damage was also associated with birthing posture, this should be considered when providing intrapartum nursing care.

The trends and associated adverse maternal and perinatal outcomes of labour neuraxial analgesia among vaginal deliveries in China between 2012 and 2019: a real-world observational evidence

BACKGROUND

There is a lack of national report of the labour neuraxial analgesia (NA) rates in China in recent years, especially after the national promotion policy. The adverse maternal and perinatal outcomes associated with NA in China are also unknown. The aim of this study is to estimate the trends of NA rates from 2012 to 2019, to evaluate the effect of national policy on promoting NA and to identify the association between NA and adverse outcomes in China.

METHODS

We used the individual data from China's National Maternal Near Miss Surveillance System (NMNMSS) between 2012 and 2019, covering 438 hospitals from 326 urban districts or rural counties in 30 provinces across China. The analysis was restricted to singleton pregnant women who underwent vaginal delivery at or after 28 completed weeks of gestation. We estimate the trends of NA rates between 2012 and 2019, both at the national and provincial levels using Bayesian multilevel model. We also estimated the effect of the national pilot policy launched in 2018 using interrupted time-series analysis and identified the association between NA and adverse outcomes using modified Poisson regression combined with propensity score analysis.

RESULTS

Over the study period, 620,851 of 6,023,046 women underwent vaginal delivery with NA. The estimated national NA rates increased from 8.4% in 2012 to 16.7% in 2019. Most provinces experienced the same rapid rise during this period. The national pilot policy accelerated the rise of the rates. No differences were observed between women with NA and without any analgesia in the incidence of uterine atony, placental retention, intrapartum stillbirths and 1- and 5-min Apgar scores lower than 7. However, women with NA had higher incidences of genital tract trauma (adjusted relative risk (aRR) 1.53, 95% confidence interval (CI) 1.04-2.26) and maternal near miss (aRR 1.35, 95% CI 1.08-1.69), only in hospitals which were not covered by the national pilot policy and usually lack of sufficient equipment and personnel.

CONCLUSIONS

The national policy can effectively increase the NA rate. However, as genital tract trauma and maternal near miss may increase in low-resource hospitals, but not in high-resource hospitals, further study is required to identify the reasons.
