Episiotomy and perineal repair practices among obstetricians in Greece

Objective

To assess current preferences regarding episiotomy and management of obstetric perineal injuries used by obstetricians in Greece, and to assess the impact of evidence-based information on everyday practices.

Methods

A questionnaire survey of obstetricians regarding episiotomy use and the management of obstetric perineal injuries.

Results

Fifty-one percent of obstetricians reported routinely performing an episiotomy during a normal vaginal delivery in primiparous women and 89% reported performing an episiotomy during vacuum-assisted deliveries. Forty-two percent of the respondents performed lateral, 44% mediolateral, and 14% midline episiotomies. Following an obstetric anal sphincter tear, half of the respondents recommended a vaginal delivery, regardless of bowel symptoms. There was significant heterogeneity of practices regarding the repair techniques of all obstetric perineal injuries.

Conclusion

The majority of obstetricians prefer to perform routine mediolateral and lateral episiotomies, for both normal and operative vaginal deliveries. The adoption of evidence-based information should be implemented while considering working and cultural backgrounds.     

Episiotomy and the risk of severe perineal injuries among Korean women*

Purpose: We examined the frequency of severe perineal injuries according to the use of episiotomy in vaginal deliveries of Korean women.

Materials and methods: This is a retrospective cohort study in which 358 consecutive parturients were included. Women were divided into episiotomy (n?=?115) and no episiotomy (n?=?243) groups. The main outcome was the occurrence of severe (third or fourth degree) perineal injuries. Delivery records and medical documents were reviewed to collect the data. Parametric and nonparametric tests were used as appropriate.

Results: There were no significant differences in the frequency of severe perineal injuries between two groups (6.1% (7/115) in episiotomy versus 3.7% (9/243) in no episiotomy group, p?=?0.308). Anterior perineal laceration was more frequent (40.3% (98/243) vs. 18.3% (21/115), p?Conclusions: There was no difference in the occurrence of severe perineal injuries according to the use of episiotomy.     

Multivariable evaluation of term birth weight: a comparison between ultrasound biometry and symphysis-fundal height

Abstract

Objective: To determine whether perineal massage during the second stage of labor using oil enriched with vitamins, increases the chances of delivering with an intact perineum as compared to perineal massage using pure liquid wax.

Method: A prospective, randomized, double-blind study was conducted. Women were assigned to liquid wax (jojoba oil) versus purified formula of almond and olive oil, enriched with vitamin B1, B2, B6, E and fatty acids. The caregivers used the oils during the second stage of labor.

Results: A total of 164 women undergoing vaginal delivery were recruited. No significant differences regarding perineal lacerations, number of sutures and length of suturing were noted between the two groups. Likewise, while analyzing separately nulliparous and multiparous women, no significant differences were noted. Controlling for birth weight >4000?g, using the Mantel–Haenszel technique, no association was noted between perineal lacerations and the type of oil used (weighted OR?=?0.9, 95% CI 0.3–2.4; p?=?0.818).

Conclusion: The type of the oil used during the second stage of labor for prevention of perineal tears has no effect on the integrity of the perineum. Accordingly, it seems that there is no perfect oil.     

Impact of Episiotomy During Operative Vaginal Delivery on Obstetrical Anal Sphincter Injuries

ObjectiveThe purpose of this study was to describe associations between episiotomy at the time of forceps or vacuum-assisted delivery and obstetrical anal sphincter injuries (OASIS).MethodsThis population-based retrospective cohort study used delivery information from a provincial perinatal clinical database. Full-term, singleton, in-hospital, operative vaginal deliveries of vertex-presenting infants from April 1, 2006 to March 31, 2016 were identified. Odds ratios (ORs) and 95% confidence intervals (CIs) for associations between episiotomy and third- or fourth-degree lacerations were calculated in multiple logistic regression models (Canadian Task Force Classification II-2).ResultsEpisiotomy was performed in 34% of 52 241 operative vaginal deliveries. OASIS occurred in 21% of forceps deliveries and 7.6% of vacuum deliveries. Episiotomy was associated with increased odds of severe perineal lacerations for vacuum deliveries among women with (OR 2.48; 95% CI 1.96–3.13) and without (OR 1.12; 95% CI 1.02–1.22) a prior vaginal delivery. Among forceps deliveries, episiotomy was associated with increased odds of OASIS for those with a previous vaginal delivery (OR 1.52; 95% CI 1.12–2.06), but it was protective for women with no previous vaginal delivery (OR 0.73; 95% CI 0.67–0.79). Midline compared with mediolateral episiotomy increased the odds of OASIS in forceps deliveries (OR 2.73; 95% CI 2.37–3.13) and vacuum deliveries (OR 1.94; 95% CI 1.65–2.28).ConclusionIn conclusion, results suggest that episiotomy should be used with caution, particularly among women with a previous vaginal delivery and in the setting of vacuum-assisted delivery. Episiotomy may protect against OASIS in forceps-assisted deliveries for women without a prior vaginal delivery.     

Trends in major modifiable risk factors for severe perineal trauma, 1996–2006

OBJECTIVE: To examine what effect the major modifiable risk factors for severe perineal trauma have had on the rates of this trauma over time. METHODS: A retrospective observational cohort study of singleton vaginal deliveries taken from a perinatal database for the period 1996 through 2006. RESULTS: A total of 46,239 singleton vertex vaginal deliveries met the inclusion criteria. Major risk factors for severe perineal trauma were increased maternal age (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.1-1.5), non-African American ethnicity (OR 1.5, 95% CI 1.3-1.7), nulliparity (OR 4.8, 95% CI 4.11-5.6), fetal birth weight (OR 2.2, 95% CI 1.9-2.4), forceps (OR 8.3, 95% CI 5.4-10.8), vacuum (OR 2.9, 95% CI 1.9-4.4), and midline episiotomy (OR 5.7, 95% CI 5.0-6.4). Evaluation of the changes in rates of these factors over the study period revealed that the decline in the rates of episiotomy and the use of forceps accounted for a reduction in severe lacerations of more than 50%. CONCLUSION: Reduction of severe perineal trauma by restricted use of the 2 modifiable clinical variables, episiotomy and forceps, is evident over time.     

Postpartum Perineal Pain in a Low Episiotomy Setting: Association with Severity of Genital Trauma,Labor Care,and Birth Variables

Background: Perineal pain is common after childbirth. We studied the effect of genital tract trauma, labor care, and birth variables on the incidence of pain in a population of healthy women exposed to low rates of episiotomy and operative vaginal delivery. Methods: A prospective study of genital trauma at birth and assessment of postpartum perineal pain and analgesic use was conducted in 565 midwifery patients. Perineal pain was assessed using the present pain intensity (PPI) and visual analog scale (VAS) components of the validated short‐form McGill pain scale. Multivariate logistic regression examined which patient characteristics or labor care measures were significant determinants of perineal pain and use of analgesic medicines. Results: At hospital discharge, women with major trauma reported higher VAS pain scores (2.16 ± 1.61 vs 1.48 ± 1.40; p < 0.001) and were more likely to use analgesic medicines (76.3 vs 23.7%, p = 0.002) than women with minor or no trauma. By 3 months, average VAS scores were low in each group and not significantly different. Perineal pain at the time of discharge was associated in univariate analysis with higher education level, ethnicity (non‐Hispanic white), nulliparity, and longer length of active maternal pushing efforts. In a multivariate model, only trauma group and length of active pushing predicted the pain at hospital discharge. In women with minor or no trauma, only length of the active part of second stage labor had a positive relationship with pain. In women with major trauma, the length of active second stage labor had no independent effect on the level of pain at discharge beyond its effect on the incidence of major trauma. Conclusions: Women with spontaneous perineal trauma reported very low rates of postpartum perineal pain. Women with major trauma reported increased perineal pain compared with women who had no or minor trauma; however, by 3 months postpartum this difference was no longer present. In women with minor or no perineal trauma, a longer period of active pushing was associated with increased perineal pain.     

Factors Influencing Perineal Trauma during Delivery

Objectives: our purpose was to evaluate risk factors for severe vaginal-perineal trauma and to ascertain determinants of pelvic floor strength.Study Design: a secondary analysis of 459 nulliparous women enrolled in a randomized controlled trial of episiotomy. In a multivariate analysis we examined the association between (1) sulcus tears, (2) third or fourth degree tears, and selected demographic, physiologic, pregnancy-related and intrapartum factors, including the role of exercise.Results: unemployment and shorter second stage of labour were significant predictors of sulcus tears. Episiotomy, forceps use and birth weight were important predictors of third and fourth degree tears. A strong exercise profile was associated with fewer third and fourth degree tears in the presence of episiotomy. Exercise did not influence the rate of sulcus tears. Exercise was not associated with the use of episiotomy.Conclusions: contrary to currently held beliefs, third and fourth degree tears are related to physician management, but the determinants of sulcus tears appear to be present before pregnancy. Exercise does not increase the need for episiotomy but does reduce the risk for associated third and fourth degree tears.     

Hospital Variation in Episiotomy Use and the Risk of Perineal Trauma During Childbirth

Background: Episiotomies are the most frequently performed surgical procedure among United States women, but there are no published epidemiological studies of the extent of variation in episiotomy use among different obstetrical providers, or the outcomes associated with different levels of use. The objective of this study was to assess the extent of hospital variation in the use of episiotomy and the relationship between hospital episiotomy use and the incidence and risk of perineal trauma among women residing in a large urban area in the United States. Methods: Linked birth certificate and hospital discharge data pertaining to births to nulliparous women without prolonged labor or obstructed deliveries, and with infants weighing between 2500 and 4000 g, were analyzed for 18 major maternity hospitals. The relationship between episiotomy use and perineal trauma at the hospital level was examined using regression analysis. Results: Hospital episiotomy rates ranged from approximately 20 to 73 percent. The rate of third or fourth degree perineal lacerations varied from a low of 4 percent to a high of more than 13 percent among hospitals. Rates of episiotomy were significantly correlated with rates of a third or fourth degree perineal laceration (r = 0.70; p < 0.01), and with the hospital‐specific, adjusted odds ratios for such lacerations (r = 0.65; p < 0.01). Conclusions: Findings from the analysis of epidemiological data for this study population were consistent with those from clinical studies, indicating that liberal as opposed to restrictive use of episiotomy is unwarranted, and probably even harmful. Hospital episiotomy rates exceeded 20 percent in all cases, but such rates appear difficult to justify in face of the evidence. (BIRTH 29:2 June 2002)     

A Randomized Study of Two Methods of Teaching Perineal Massage: Effects on Practice Rates,Episiotomy Rates,and Lacerations

ABSTRACT: This study examined the effects of two methods of teaching perineal massage on the rates of practice of perineal massage, of episiotomy, and of lacerations in primiparas at birth. Couples in 20 randomly selected sections of four prenatal class series received routine printed and verbal instruction and a 12-minute video demonstration of perineal massage, or only the routine printed and verbal instruction. Women reported their practice rates in daily diary records, which were mailed to the researcher weekly. Hospital records provided delivery data. Of the 83 women, 23 (28%) practiced perineal massage: 16 (35.6%) in the experimental group, 7 (18.4%) controls. Even though the rate of practice almost doubled among experimental group women, the videotape instruction method was statistically nosignificant. Episiotomy and laceration rates were not affected by teaching method. More severe lacerations occurred among the experimental group; however, the control group had almost four times as many severe (21%) as minor (5.3%) lacerations. The experimental group had twice as many severe (28.9%) as minor (13.3%) lacerations. These results were also nosignificant.     

Episiotomy pain: Efficacy and safety of fluproquazone compared to aspirin and placebo

The analgesic efficacy of fluproquazone at 100 mg and 200 mg doses, was measured in 160 patients with episiotomy pain and was compared to that of aspirin (650 mg) and placebo. The 100-mg dose of fluproquazone was more effective in relieving episiotomy pain than the 200-mg dose of fluproquazone, aspirin or placebo in terms of mean pain intensity scores after 1 h. All active compounds were more effective than placebo by all criteria.     

Implementation of Episcissors-60 for Prevention of Obstetric Anal Sphincter Injuries (OASIS) in a Centre with Low Episiotomy Rates

ObjectiveThe purpose of this study was to determine whether introduction of Episcissors-60 into a labour and birth unit would decrease the incidence of obstetric anal sphincter injuries (OASIS).MethodsA before and after quality improvement study was conducted between April 1, 2020, and March 31, 2021. All patients who had a vaginal delivery were included in this study. All healthcare providers who perform vaginal deliveries were offered an educational session. Episcissors-60 were then introduced into a labour and birth unit. The primary outcome measure was the change in incidence of OASIS before and after introduction of Episcissors-60. Secondary outcome measures were episiotomy rates before and after introduction of Episcissors-60, device-related adverse events, and provider satisfaction and feedback. Data were analyzed using chi-square tests, independent t tests, and Mann-Whitney tests.ResultsA total of 1383 vaginal deliveries occurred before and 1254 vaginal deliveries after introduction of Episcissors-60. There was a decrease in the total OASIS rate from 7.37% of all vaginal deliveries before and 5.37% after introduction of Episcissors-60 (P = 0.037). The episiotomy rate was 11.42% before and 9.97% after introduction of Episcissors-60 (P = 0.228). OASIS rate in women who had an episiotomy was 12.02% before and 13.60% after introduction of Episcissors-60 (P = 0.421).ConclusionAlthough introduction of Episcissors-60 was associated with a statistically significant decrease in total OASIS rate, there was no difference in OASIS rate within the subgroup that received an episiotomy. Therefore, reduction in the total OASIS rate in this study cannot be attributed to the use of Episcissors-60.     

Perineal Trauma and Postpartum Perineal Morbidity in Asian and Non-Asian Primiparous Women Giving Birth in Australia

Objectives: To describe the postpartum perineal morbidity of primiparous women who had a vaginal birth and compare outcomes between Asian and non-Asian women in the first 2 days following the birth and at 6 and 12 weeks postpartum.
Design: Data from a randomized clinical trial of a perineal management technique (perineal warm packs) were used to address the study objective.
Setting: Two maternity hospitals in Sydney, Australia.
Participants: Primiparous women who had a vaginal birth in the trial were included ( n =697). One third of the women were identified as "Asian."
Results: Compared with non-Asian women, Asian women were significantly more likely to have an episiotomy; require perineal suturing; sustain a third- or fourth-degree perineal tear; and report their perineal pain as being moderate to severe on day 1 following the birth. Asian women were less likely to give birth in an upright position or to resume sexual intercourse by 6 or 12 weeks following the birth.
Conclusion: More research is needed into methods that could reduce the high rates of perineal trauma experienced by Asian women, and midwives need to be able to offer appropriate support for Asian women.

Episiotomy pain relief: Use of Lavender oil essence in primiparous Iranian women

Introduction

Post-episiotomy discomfort and its consequences can affect maternal quality of life and mental health as well as the mother and baby relationship. Complementary medicine is increasingly used and Lavender oil is frequently prescribed due to its antiseptic and healing properties.

Method

This clinical trial involved 60 qualified primiparous women admitted for labor in Kamali Hospital in Karaj, Iran. They were randomly categorized into two groups: case (using Lavender oil) and control (usual hospital protocol). Participants pain and discomfort were recorded using a Visual Analogue Scale (VAS) and a Redness, Edema, Ecchymosis, Discharge Scale (REEDA). Pain was evaluated at 4 h, 12 h and 5 days following episiotomy. Collected data was analyzed in SPSS 14 using an independent t-test and chi-square.

Results

There was a statistical difference in pain intensity scores between the 2 groups after 4 h (p = 0.002, and 5 days (p = 0.000) after episiotomy. However, differences in pain intensity between the two groups, at 12 h post-surgery, were not significant (p = 0.066). The REEDA score was significantly lower in the experimental group (Lavender oil group) 5 days after episiotomy (p = 0.000).

Conclusion

According to these findings, use of Lavender oil essence can be effective in reducing perineal discomfort following episiotomy. It is suggested that Lavender oil essence may be preferably to the use of Betadine for episiotomy wound care.
