Risk factors for episiotomy: a case-control study

Magnitude of episiotomy practice and associated factors among women who gave birth at Hiwot Fana Specialized University Hospital, Eastern Ethiopia

BACKGROUND

Episiotomy is an intentional surgical incision made on the perineum with the aim of enlarging the introits during the second stage of labor or just before delivery of the baby. It sometimes also interferes with the mother's comfort during the postpartum period and has associated complications especially when it is done without indication. However, there is limited information regarding episiotomy practice in the study area.

OBJECTIVE

This study aimed to determine the magnitude of episiotomy practice and associated factors among women who gave birth at the Hiwot Fana Specialized University Hospital, Eastern Ethiopia, 2021.

METHODS

A facility-based cross-sectional study was conducted among 408 systematically selected mothers who gave birth at the Hiwot Fana Specialized University Hospital, from 1 January to 30 December 2021. Datas were collected from delivery medical records using a pretested checklist. The extracted data were checked, coded, and entered into the Epi-data version 3.1 and exported to the STATA version 16 software for analysis. Binary logistic regression was fitted to identify factors associated with episiotomy practice. P-values < 0.05 were considered to declare the presence of statistical significance.

RESULTS

The overall prevalence of episiotomy practice was found to be 43.4 % (95% CI: 38.7, 48.9), and mediolateral was the most commonly practiced episiotomy type (41.4%). Parity [AOR: 6.2; 95% CI (3.8-17.6)], 1st min Apgar score [AOR: 1.6; 95% CI (1.04-2.67)], presence of maternal medical disease [AOR: 3.3; 95% CI (1.09-6.9)], and induced labor [AOR: 1.6; 95%CI (1.12, 4.13)] were significantly associated with the episiotomy practice.

CONCLUSION

The prevalence of episiotomy practice in the study area was high. Parity, presence of maternal medical disease, induction of labor, and 1st min APGAR score were significant factors associated with episiotomy practice. Considering the presence of appropriate indications or preventing unjustifiable indications, can help to reduce the current high practice rates.

Episiotomy for Medical Indications during Vaginal Birth-Retrospective Analysis of Risk Factors Determining the Performance of This Procedure

The WHO (World Health Organization) recommends that the percentage of perineal incisions should not exceed 10%, indicating that this is a good goal to achieve, despite the fact that it is still a frequently used medical intervention in Poland. The risk factors for perineal incision that have been analyzed so far in the literature allow, among others, to limit the frequency of performing this procedure. Are they still valid? Have there been new risk factors that we should take into account? We have conducted this study to find the risk factors for performing perineal incision that would reduce the frequency of this procedure. The aim of the study was to check whether the risk factors that were analyzed in the literature are still valid, to find new risk factors for perineal incisions and to compare them among Polish women. This was a single-center retrospective case-control study. The electronic patient records of Saint Sophia's Hospital in Warsaw, Poland, a tertiary hospital was used to create an anonymous retrospective database of all deliveries from 2015 to 2020. The study included the analysis of two groups, the study group of patients who had had an episiotomy, and the control group-patients without an episiotomy in cases where an episiotomy was indicated. A logistic regression model was developed to assess the risk factors for perineal laceration. Independent risk factors for episiotomy in labor include oxytocin use in the second stage of labor (OR (Odds Ratio) = 6.00; 95% CI (Confidence Interval): 4.76-7.58), the supply of oxytocin in the first and the second stage of labor (OR = 3.18; 95% CI: 2.90-3.49), oxytocin use in the first stage of labor (OR = 2.72; 95% CI: 2.52-3.51), state after cesarean section (OR = 2.97; 95% CI: 2.52-3.51), epidural anesthesia use (OR = 1.77; 95% CI: 1.62-1.93), male gender (OR = 1.10; 95% CI: 1.02-1.19), and prolonged second stage of labor (OR = 1.01; 95% CI: 1.01-1.01). A protective factor against the use of an episiotomy was delivery in the Birth Centre (OR = 0.43; 95% CI: 0.37-0.51) and mulitpara (OR = 0.31; 95% CI: 0.27-0.35). To reduce the frequency of an episiotomy, it is necessary consider the risk factors of performing this procedure in everyday practice, e.g., limiting the use of oxytocin or promoting alternative places of delivery.

Racial variations of adverse perinatal outcomes: A population-based retrospective cohort study in Ontario, Canada

Introduction

Racial differences in adverse maternal and birth outcomes have been studied in other countries, however, there are few studies specific to the Canadian population. In this study, we sought to examine the inequities in adverse perinatal outcomes between Black and White pregnant people in Ontario, Canada.

Methods

We conducted a population-based retrospective cohort study that included all Black and White pregnant people who attended prenatal screening and had a singleton birth in any Ontario hospital (April 1^st, 2012-March 31^st, 2019). Poisson regression with robust error variance models were used to estimate the adjusted relative risks of adverse perinatal outcomes for Black people compared with White people while adjusting for covariates.

Results

Among 412,120 eligible pregnant people, 10.1% were Black people and 89.9% were White people. Black people were at an increased risk of gestational diabetes mellitus, preeclampsia, placental abruption, preterm birth (<37, <34, <32 weeks), spontaneous preterm birth, all caesarean sections, emergency caesarean section, low birth weight (<2500g, <1500g), small-for-gestational-age (<10th percentile, <3^rd percentile) neonates, 5-minute Apgar score <4 and <7, neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment but had lower risks of elective caesarean section, assisted vaginal delivery, episiotomy, 3rd and 4th degree perineal tears, macrosomia, large-for-gestational-age neonates, and arterial cord pH≤7.1, as compared with White people. No difference in risks of gestational hypertension and placenta previa were observed between Black and White people.

Conclusion

There are differences in several adverse perinatal outcomes between Black and White people within the Ontario health care system. Findings might have potential clinical and health policy implications, although more studies are needed to further understand the mechanisms.

Episiotomy Practice and Its Associated Factors in Africa: A Systematic Review and Meta-Analysis

Background

Episiotomy, a surgical procedure that enlarges the vaginal opening during childbirth, was common practice until the early 2000s. Other sources, including the World Health Organization (WHO), advocate for the selective use of episiotomy. Episiotomy rates, on the other hand, have remained high in developing countries, while declining in developed countries. As a result, the current study sought to determine the overall prevalence of episiotomy in Africa as well as the risk factors associated with its practice.

Methods

Articles were searched in international electronic databases. A standardized Microsoft Excel spreadsheet and STATA software version 14 were used for data extraction and analysis, respectively. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist was used to write this report. A random-effects meta-analysis model was used to determine the pooled prevalence of episiotomy. A heterogeneity test was conducted using I-Squared (I²) statistics. Egger's test and funnel plots were conducted to detect publication bias. Subgroup analysis was also conducted. Association was expressed through a pooled odds ratio (OR) with a 95% Confidence Interval (CI).

Result

A total of 21 studies with 40,831 participants were included in the systematic review and meta-analysis. The pooled prevalence of episiotomy practice was 41.7% [95% CI (36.0–47.4), I² = 99.3%, P < 0.001). Primiparity [OR: 6.796 (95% CI (4.862–9.498)), P < 0.001, I²: 95.1%], medical doctors- assisted delivery [OR: 3.675 (95% CI (2.034–6.640)), P < 0.001, I²: 72.6%], prolonged second stage of labor [OR: 5.539 (95% CI (4.252–7.199)), P < 0.001, I²: 0.0%], using oxytocin [OR: 4.207 (95% CI (3.100–5.709)), P < 0.001, I²: 0.0%], instrument -assisted vaginal delivery [OR: 5.578 (95% CI (4.285–7.260)), P < 0.001, I²: 65.1%], and macrosomia [OR: 5.32 (95% CI (2.738–10.339)), P < 0.001, I²: 95.1%] were factors associated with episiotomy practice.

Conclusion

In this review, the prevalence of episiotomy among African parturients was high. A selective episiotomy practice should be implemented to reduce the high episiotomy rates.

Prevalence of episiotomy practice and factors associated with it in Ethiopia, systematic review and meta-analysis

An episiotomy is one of the most commonly performed obstetrics surgeries indicated in emergencies during the second stage of labor like fetal distress, dystocia, and tight perineum. As a result, this systematic review and meta-analysis aimed to assess the prevalence of episiotomy practice and associated factors in Ethiopia. Ten cross-sectional studies with a total population of 3718 were included in this study. The search was done using online databases like PubMed, HINARI, Web of Science, other gray, and online repositories of Universities. All the included papers were extracted and appraised using the standard extraction sheet format of JOANNA Briggs Institute. The Cochran Q-test and I² statistics test were used to test the heterogeneity of studies. To detect the publication bias of the included studies, a funnel plot and Egger's test were used. The pooled prevalence of episiotomy practice and the odds ratio with a 95% confidence interval were presented using forest plots. The overall pooled prevalence of episiotomy practice was 45.11% (95% CI; 37.04-53.18; I² = 96.3%). Prolonged second stage of labor (OR: 4.79, 95% CI: 3.03, 7.57), face presentation (OR: 4.26, 95% CI: 1.21, 15.07), birth weight > 4000 g (OR: 6.71, 95% CI: 3.14-14.33), instrumental delivery (OR: 4.26, 95% CI 2.95, 6.14), and primiparity (OR: 3.70, 95% CI: 1.90, 7.2) were factors associated with episiotomy practice. The overall prevalence of episiotomy practice was higher in Ethiopia compared to studies conducted in other countries. The prolonged second stage of labor, face presentation, birth weight > 4000 g, instrumental delivery, and primiparity of women were the factors associated with episiotomy practice. Therefore, efforts should be made to prevent routine episiotomy practice through creating awareness, adjusting national guidelines, affecting the World Health Organization episiotomy policy, and monitoring the activities of the health care facilities in executing the protocols.

Episiotomy practice and associated factors among mothers who gave birth at public health facilities in Metema district, northwest Ethiopia

BACKGROUND

Episiotomy is a surgical incision of the perineum to hasten the delivery. There is a scarce of information related to episiotomy practice, and its associated factors, in developing countries, including Ethiopia. Thus, this study was aimed to determine the level of episiotomy practice and to identify its determinants at public health facilities of Metema district, northwest, Ethiopia.

METHODS

Institutional-based cross sectional study was conducted among 410 delivered mothers from March 1 to April 30, 2020. We recruited study participants using systematic random sampling technique. Data were entered to Epi data version 3.1 and exported to STATA version 14 for statistical analysis. Stepwise backward elimination was applied for variable selection and model fitness was checked using Hosmer and Lemshows statistics test. Adjusted odds ratio with the corresponding 95% confidence interval was used to declare the significance of variables.

RESULTS

In this study, the magnitude of episiotomy practice was found 44.15% (95% CI 39.32-48.97). Vaginal instrumental delivery (AOR 3.04, 95% CI 1.36-6.78), perineal tear (AOR 3.56, 95% CI 1.68-7.55), age between 25 and 35 (AOR 0.11, 95% CI 0.05-0.25), birth spacing less than 2 years (AOR 4.76, 95% CI 2.31-9.83) and use of oxytocin (AOR 2.73, 95% CI 1.19-6.25) were factors significantly associated with episiotomy practice.

CONCLUSIONS

Magnitude of episiotomy practice in this study is higher than the recommended value of World Health Organization (WHO). Instrumental delivery, age, oxytocin, birth spacing and perineal tear were significant factors for episiotomy practice. Thus, specific interventions should be designed to reduce the rate of episiotomy practice. Plain English summary The routine use of episiotomy practice is not recommended by WHO. A study that compares routine episiotomy with restrictive episiotomy suggests that the latter is associated with less posterior perineal trauma, less need for suturing, and fewer complications related to healing. In addition, though, the rate of episiotomy has been declined in developed countries, still it remains high in less industrialized countries. The data for this study were taken at public health facilities of Metema district, northwest, Ethiopia. We included a total of 410 delivered mothers. The magnitude of episiotomy practice was found 44%. This result was higher than the recommended value of WHO. The WHO recommends an episiotomy rate of 10% for all normal deliveries. The result of this study showed that episiotomy practice is common among mothers whose age group are 18-24. In addition, mothers whose labor were assisted by instrumental vaginal delivery are more likely to have episiotomy as compared to those delivered by normal vaginal delivery. Laboring mothers who had used oxytocin were about three times more likely to be exposed for episiotomy than laboring mothers who did not use oxytocin drug. Moreover, episiotomy practice was nearly five times more likely among mothers who had birth spacing of 2 years and less as compared to mothers who had birth spacing of more than 2 years.

Assessing the Impact of Obesity on Pregnancy and Neonatal Outcomes among Saudi Women

Background: The rising prevalence of obesity has a significant impact on obstetrics practice regarding maternal and perinatal complications includes recurrent miscarriage, pregnancy-induced hypertension, preeclampsia, gestational diabetes, and prolonged labor. Objective: To assess the impact of obesity on pregnancy and neonatal outcomes among Saudi women. Methods: The study was conducted at King Abdul-Aziz Medical City, Jeddah. Design: A cross-sectional retrospective design. A total number of 186 participants were recruited from July to December 2018 according to eligibility criteria. The data were collected retrospectively by a review of the chart records of the labor and delivery department. Results: The mean (SD) age of participants was 31.94 (5.67) years old; two-thirds were in obesity class I. There was a significant association between obesity and pre-existing thyroid disease and induced hypertension class III. However, episiotomy showed that obesity class III was significantly different from obesity class II. Conclusion: This study concludes obesity affects the outcomes of pregnant Saudi associations between obesity and preeclampsia, perineal tears, and episiotomy variables, and other variables reflect no associations. Recommendations: Further studies are needed to generalize the results. This study endorses the pregnant women start the antenatal follow-up from 1st trimester so, the data will be available on the system for research.

Factors Associated with Episiotomy Practices in Bahirdar City, Ethiopia: A Cross-Sectional Study

Background

Episiotomy is the surgical enlargement of the vaginal orifice during the last part of the second stage of labor or childbirth by an incision to the perineum. The World Health Organization advises the use of episiotomy on a restricted and selective basis. Indeed, the rate of episiotomy in developed countries is decreasing, but in developing countries, including Ethiopia, it still remains high. Therefore, this study tried to assess the proportion and factors associated with episiotomy among women who gave birth at Felege Hiwot Referral Hospital, Bahir Dar City, North West Ethiopia, 2017.

Methods

An institution-based cross-sectional study was conducted among 411 mothers from February to April 2017. Data were collected through face-to-face interviews and supported by observation using standard checklist with systematic random sampling technique. Data was entered by Epi Info and analyzed by SPSS version 23. The association between variables was analyzed using bivariable and multivariable logistic regression model. P-value <0.05 at 95% CI was considered to be statistically significant.

Results

The proportion of episiotomy was 41.1% with 95% CI (36.5%, 46.2%). Multivariable logistic regression showed that primiparity (AOR=6.026, 95% CI (3.542,10.253)), prolonged second stage of labor (AOR=4.612, 95% CI (2.247,9.465)), instrument delivery (AOR =3.933, 95% CI (1.526,10.141)), using oxytocin (AOR=2.608, 95% CI (1.431,4.751)), medical resident attendant (AOR =3.225, 95% CI (1.409,7.382)) and birth weight ≥4000 grams (AOR=5.127,95% Cl (1.106,23.772)) were significantly associated with episiotomy practice.

Conclusion

The proportion of episiotomy was high. Parity, using oxytocin, second-stage labor duration, instrument delivery, birth weight, and delivery attendant were statistically significant factors for episiotomy practice. Therefore, as per our findings, we suggest awareness creation, and the setting and use of new national guidelines, the practice of routine episiotomy should be abandoned, and selective and restrictive use of episiotomy is highly advised.

Hospital obstetric practices and their repercussions on maternal welfare

OBJECTIVE

To analyze the association of care practices performed by obstetric professionals with maternal welfare/malaise levels.

METHOD

A quantitative study conducted in a Prepartum/Childbirth/Postpartum Unit of a Teaching Hospital with puerperal women who underwent vaginal births. An association was performed between obstetric practices and maternal welfare/malaise levels.

RESULTS

There were 104 puerperal women who participated. Obstetric practices which caused mothers to feel unwell and which obtained statistical significance were: amniotomy (p = 0.018), episiotomy (p = 0.05), adoption of horizontal positions in the expulsive period (p = 0.04), the non-use of non-invasive care technologies (p = 0.029), and non-skin-to-skin contact between mother and child (p = 0.002). For most women, the presence of a companion favored welfare, even though it did not have a statistically significant association. After performing logistic regression, non-performance of amniotomy was the only variable which showed significance in maternal welfare.

CONCLUSION

Humanized obstetric practices have greater potential to promote maternal welfare. The importance of obstetric nurses conducting practices which provide greater welfare to mothers is emphasized.

Factors related to perineal outcome after vaginal delivery in primiparas: a cross-sectional study

OBJECTIVE

Identify the associations between perineal outcome in primiparas and interventions during labor and delivery, newborn weight and APGAR score.

METHOD

Document-based, correlational, retrospective, quantitative study conducted in a tertiary maternity hospital in the state of Ceará, between July 2017 and January 2018. The independent variables were labor induction, amniotomy, non-pharmaceutical methods for relieving pain, forceps, episiotomy, Kristeller maneuver, position in the expulsion stage, shoulder dystocia, and newborn weight and APGAR score, and the dependent variable was perineal outcome. Pearson's chi-square test and Fisher's exact test were used.

RESULTS

A total of 226 normal-risk primiparas who had a vaginal delivery. An association was found between horizontal position in the expulsion stage and episiotomy, and between not performing an episiotomy and perineal tearing. The other variables (labor, delivery and neonatal) did not have any effect on perineal tearing.

CONCLUSION

Interventions, with the exception of episiotomies, did not have an influence on the occurrence of perineal trauma, but they do need to be carefully assessed. Deliveries in a horizontal position were associated with a higher likelihood of performing an episiotomy.

Birth-Related Perineal Trauma in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis

Introduction Birth-related perineal trauma (BPT) is a common consequence of vaginal births. When poorly managed, BPT can result in increased morbidity and mortality due to infections, haemorrhage, and incontinence. This review aims to collect data on rates of BPT in low- and middle-income countries (LMICs), through a systematic review and meta-analysis. Methods The following databases were searched: Medline, Embase, Latin American and Caribbean Health Sciences Literature (LILACs), and the World Health Organization (WHO) regional databases, from 2004 to 2016. Cross-sectional data on the proportion of vaginal births that resulted in episiotomy, second degree tears or obstetric anal sphincter injuries (OASI) were extracted from studies carried out in LMICs by two independent reviewers. Estimates were meta-analysed using a random effects model; results were presented by type of BPT, parity, and mode of birth. Results Of the 1182 citations reviewed, 74 studies providing data on 334,054 births in 41 countries were included. Five studies reported outcomes of births in the community. In LMICs, the overall rates of BPT were 46% (95% CI 36–55%), 24% (95% CI 17–32%), and 1.4% (95% CI 1.2–1.7%) for episiotomies, second degree tears, and OASI, respectively. Studies were highly heterogeneous with respect to study design and population. The overall reporting quality was inadequate. Discussion Compared to high-income settings, episiotomy rates are high in LMIC medical facilities. There is an urgent need to improve reporting of BPT in LMICs particularly with regards to births taking in community settings.

Practices and obstetric interventions in women from a state in the Northeast of Brazil

OBJECTIVE

To describe practices and interventions used during labor and childbirth and factors associated with such practices in puerperae in the state of Sergipe.

METHOD

A cross-sectional study with 768 postpartum women from 11 maternity hospitals interviewed 6 hours after delivery, and hospital records review. The associations between best practices and interventions used during labor and delivery with exposure variables were described using simple frequencies, percentages, crude and adjusted odds ratio (ORa) with the confidence interval.

RESULTS

Of the women in the study, 10.6% received food and 27.8% moved during labor; non-pharmacological methods for pain relief were performed in 26.1%; a partogram was filled in 39.4% of the charts; and an accompanying person was present in 40.6% of deliveries. Oxytocin, amniotomy and labor analgesia were used in 59.1%, 49.3% and 4.2% of women, respectively. Lithotomy position during childbirth was used in 95.2% of the cases, episiotomy in 43.9% and Kristeller maneuver in 31.7%. The variables most associated with cesarean section were private financing (ORa=4.27, 95CI 2.44-7.47), higher levels of education (ORa=4.54, 95CI 2.56-8.3) and high obstetric risk (ORa=1.9, 95CI 1.31-2.74). Women whose delivery was funded privately were more likely to have an accompanying person present (ORa=2.12, 95CI 1.18-3.79) and to undergo labor analgesia (ORa=4.96, 95CI 1.7-14.5).

CONCLUSION

Best practices are poorly performed and unnecessary interventions are frequent. The factors most associated with c-section were private funding, greater length of education and high obstetric risk.

Scientific evidence on perineal trauma during labor: Integrative review

OBJECTIVE

To assess the scientific evidence for management and preservation of perineal integrity during the expulsive stage of labor.

STUDY DESIGN

Integrative review that employed the Population, Intervention, Comparison, Outcome strategy to formulate the research question: Which perineal measure(s) is(are) effective in maintaining perineal integrity during labor? The search was performed in the databases MEDLINE, LILACS, BDENF and SciELO. The ten selected studies were analyzed based on their level of evidence and grade of recommendation.

RESULTS

Four categories of measures were located: antenatal perineal care, perineal massage during the expulsive phase of labor, manual perineal support during the expulsive phase of labor and perineal hyaluronidase injection.

CONCLUSION

Based on its level of evidence, perineal massage with lubricants performed by the women or their partners at the end of pregnancy may be recommended as a measure favorable for perineal protection.

Incidence of episiotomy in Slovenia: The story behind the numbers

Episiotomy is a surgical cut of the perineum performed in the second stage of labor in order to widen the vaginal opening and thus facilitate the birth of an infant. Despite current recommendations against the routine use of episiotomy, it is one of the most commonly performed surgical interventions during childbirth. This retrospective study explores the number of episiotomies performed in Slovenian maternity hospitals and the differences in episiotomy rates in relation to parity. Data were obtained from the Slovenian National Perinatal Information System and pooled for 2013. A causal and non-experimental method of empirical research was used. The results of the study show that episiotomy rates vary widely across Slovenian maternity hospitals, ranging from 2.5% to 51.7%. Moreover, the majority of Slovenian maternity hospitals exceed the recommended rate, with an overall incidence of episiotomy as high as 31.3%. Further research is recommended to obtain relevant information from women as well as from midwives and to draw new, evidence-based conclusions related to the maternal benefits and adverse effects of episiotomy.

Humanized Care: insertion of obstetric nurses in a teaching hospital

Objective:

to evaluate the care provided at an Antepartum, Intrapartum, Postpartum (AIP) unit at a teaching hospital following the inclusion of obstetric nurses.

Method:

transversal study, performed at a AIP unit at a teaching hospital in the capital of the Brazilian state of Mato Grosso. The sample comprised data regarding the 701 childbirths that took place between 2014 and 2016. The data were organized using Excel and analyzed using version 7 of Epi Info software.

Results:

the results suggest that including obstetric nurses contributed towards qualifying the care provided during labor and childbirth, followed by a reduction in the number of interventions, such as episiotomy caesareans sections, and resulting in encouragement to employ practices that do not interfere in the physiology of the parturition process, which in turn generate good perinatal results.

Conclusion:

inserting these nurses collaborated towards humanizing obstetric and neonatal care.
