The association of obstetric anal sphincter injury and mediolateral episiotomy with increasing birth weight and duration of second stage of labour in spontaneous vaginal delivery.

OBJECTIVES: Analysis of the association of mediolateral episiotomy (MLE) with obstetric anal sphincter injury (OASI) in women with spontaneous vaginal delivery. DESIGN: Population-based cohort study with data from the Netherlands Perinatal Registry, describing 541 055 women who delivered a singleton live born infant in cephalic presentation spontaneously at term. Risk indicators for OASI were tested using univariate and multivariate analysis. Additional analysis for the interaction of MLE with other risk indicators was performed. RESULTS: The rate of OASI was 4.2 % in 215 241 nulliparous and 1.4 % in 325 814 multiparous women. In nulliparous and multiparous women MLE was associated with a reduction of OASI (adjusted OR (aOR) 0.3, 95 % CI 0.30-0.34 and aOR 0.32, 95 % CI 0.30-0.34). The association of MLE with a reduced rate of OASI was stronger in high birthweight and in prolonged 2nd stage groups. In nulliparous women, the number needed to treat (NNT) for the use of MLE to prevent one OASI is 31 in general. With MLE, the OASI rate reduced from 11.5 % to 2.9 with a NNT of 12 in the group with a birth weight ≥ 4000 g and a duration of the second stage of labour of 60-120 min. The NNT is 9 In the group with a birth weight ≥ 4000 g and a duration of the second stage of labour ≥ 120 min (reduction rate of OASI from 14.2 % to 3.5 %). CONCLUSIONS: Use of MLE is associated with a reduction of OASI in spontaneous vaginal delivery. In nulliparous women, an episiotomy with an anticipated birth weight > 4000 g and a duration of the 2nd stage of more than 60 min should be considered.

Perineal techniques during the second stage of labour for reducing perineal trauma and postpartum complications.

RATIONALE: Postpartum haemorrhage (PPH) is responsible for around 27% of global maternal deaths. Perineal tears are common in vaginal births and a significant contributor to excessive blood loss. A diversity of perineal techniques are utilised to prevent perineal trauma and reduce the incidence of PPH; however, they lack evidence-based comparisons to understand their effects. OBJECTIVES: To assess the effect of perineal techniques during the second stage of labour on the incidence of and morbidity associated with perineal trauma to prevent postpartum complications. SEARCH METHODS: We searched four databases and two trial registers up to 16 April 2024. We checked references, searched citations and contacted study authors to identify additional studies. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCTs) of women in the second stage of labour who intended to give birth vaginally, comparing any perineal techniques with control or another perineal technique. We excluded studies that performed perineal techniques outside the second stage of labour. OUTCOMES: Our critical outcomes were second-, third- and fourth-degree tears measured immediately after birth, and PPH ≥ 500 mL measured within 24 hours after birth. RISK OF BIAS: We used the Cochrane risk of bias 2 tool to assess bias in the included RCTs. SYNTHESIS METHODS: We synthesised results for each outcome within each comparison using meta-analysis where possible. Where this was not possible due to the nature of the data, we synthesised results narratively. We used GRADE to assess the certainty of evidence for each outcome. INCLUDED STUDIES: We included a total of 17 studies with 13,695 participants. SYNTHESIS OF RESULTS: Hands off (or poised) versus hands on Hands off (poised) may result in little to no difference in second-degree tears (risk ratio (RR) 0.73, 95% confidence interval (CI) 0.32 to 1.64; 2 studies; low-certainty evidence) and third- or fourth-degree tears when data are combined (RR 1.27, 95% CI 0.81 to 1.99; 2 studies; low-certainty evidence). The evidence is very uncertain about the effect of hands off (poised) on third-degree tears and fourth-degree tears when reported separately (RR 0.50, 95% CI 0.05 to 5.27; 1 study; very low-certainty evidence and RR 3.00, 95% CI 0.13 to 71.22; 1 study; very low-certainty evidence). Hands off (poised) may result in little to no difference in PPH ≥ 500 mL (RR 1.16, 95% CI 0.92 to 1.47; 1 study; low-certainty evidence). Hands off (poised) probably results in little to no difference in breastfeeding two days after birth (RR 1.02, 95% CI 0.99 to 1.06; 1 study; moderate-certainty evidence) and perineal pain (RR 0.98, 95% CI 0.94 to 1.01; 1 study; moderate-certainty evidence). Vocalisation versus control Vocalisation may result in a reduction in second-degree tears (RR 0.56, 95% CI 0.23 to 1.38; 1 study; low-certainty evidence) and third-degree tears (RR 0.13, 95% CI 0.01 to 2.32; 1 study; low-certainty evidence), but the CIs are wide and include the possibility of no effect. No events were reported for fourth-degree tears (low-certainty evidence). Vocalisation may increase maternal satisfaction (RR 1.19, 95% CI 0.93 to 1.51; 1 study; low-certainty evidence). The evidence is very uncertain about the effect of vocalisation on perineal pain (RR 1.44, 95% CI 0.81 to 2.58; 1 study; very low-certainty evidence). Warm compress on the perineum versus control (hands off or no warm compress) Warm compress on the perineum may result in little to no difference in second-degree tears (RR 0.94, 95% CI 0.72 to 1.21; 2 studies; low-certainty evidence), but likely results in a reduction in third- or fourth-degree tears (RR 0.46, 95% CI 0.27 to 0.79; 3 studies; moderate-certainty evidence). Evidence from two smaller studies is very uncertain about the effect of warm compress on the perineum on third-degree tears (RR 0.51, 95% CI 0.04 to 7.05; 2 studies; very low-certainty evidence) or fourth-degree tears (RR 0.11, 95% CI 0.01 to 2.06; 2 studies; very low-certainty evidence) when reported separately. Warm compress likely results in a large reduction in perineal pain (mean difference (MD) -0.81, 95% CI -1.18 to -0.44; 1 study; moderate-certainty evidence). The evidence is very uncertain about the effect of warm compress on the perineum on maternal satisfaction and PPH ≥ 500 mL. Massage of the perineum versus control (hands off or no usual care) Massage of the perineum may have little to no effect on second-degree tears (RR 1.04, 95% CI 0.89 to 1.21; 4 studies; low-certainty evidence). The evidence is very uncertain about the effect of massage of the perineum on third-degree tears (RR 0.57, 95% CI 0.16 to 2.02; 4 studies; very low-certainty evidence). Massage of the perineum may reduce fourth-degree tears but the CIs are wide and include the possibility of no effect (RR 0.26, 95% CI 0.04 to 1.61; 4 studies; low-certainty evidence). The evidence suggests that massage likely results in little to no difference in perineal pain (RR 0.97, 95% CI 0.90, 1.05; 1 study; moderate-certainty evidence). One study reported 10 participants with postpartum haemorrhage across three interventions (warm compress, massage, control). Combined warm compress and massage of the perineum versus control Combined warm compress and massage of the perineum likely results in a reduction in second-degree tears when compared to a control (RR 0.63, 95% CI 0.46 to 0.86; 1 study; moderate-certainty evidence), but the evidence is very uncertain about the effect on third-degree tears (RR 2.92, 95% CI 0.12 to 70.72; 1 study; very low-certainty evidence). The intervention may result in a reduction in PPH ≥ 500 mL but the CIs are wide and include the possibility of no effect (RR 0.43, 95% CI 0.14 to 1.35; 1 study; low-certainty evidence). Combined warm compress and massage likely results in an increase in maternal satisfaction (MD 0.4, 95% CI -0.01 to 0.81; 1 study; moderate-certainty evidence). Combined warm compress and massage of the perineum versus massage alone Combined warm compress and massage of the perineum may result in little to no difference in second-degree tears (RR 0.95, 95% CI 0.86 to 1.06; 1 study; low-certainty evidence) when compared to massage alone, but the evidence is very uncertain about the effect on third- or fourth-degree tears (RR 0.98, 95% CI 0.06 to 15.49; 1 study; very low-certainty evidence). It may also result in little to no difference in PPH ≥ 500 mL (RR 1.10, 95% CI 0.59 to 2.07; 1 study; low-certainty evidence). The evidence suggests that combined warm compress and massage may result in little to no difference in maternal satisfaction (1 study; low-certainty evidence). Other perineal techniques We also assessed evidence on the following comparisons, but since they are used less frequently in global clinical practice to optimise birth outcomes, we have not presented the results summary here: Ritgen's manoeuvre versus standard care; primary delivery of posterior versus anterior shoulder; massage with enriched oil on the perineum versus massage with liquid wax; petroleum jelly on the perineum versus control; and perineal protection device versus control. AUTHORS' CONCLUSIONS: Overall, the evidence for the effectiveness of perineal techniques to reduce perineal trauma and postpartum haemorrhage is very uncertain. Very few studies reported rates of postpartum haemorrhage, adverse events, women's or health workers' experience or other important outcomes that allow us to understand the effectiveness and acceptability of perineal techniques to reduce perineal trauma. Prior to any further large trials, research is needed to clarify the types of interventions, including a clear description of the process of development and involvement of relevant stakeholders. There is a need to clarify how the intervention is proposed to achieve its effects. Trials would benefit from process evaluation alongside, to explore context, mechanisms and effects.

Epidural injection of hydromorphone for postoperative pain after episiotomy: a randomized controlled trial.

Perineal incision resulting in post-partum pain and impact on puerperal life was the focus of our study. We recruited postpartum mothers who had undergone vaginal delivery to receive labor analgesia and episiotomy with an epidural injection of 0.5 mg hydromorphone to assess the therapeutic effects of postpartum analgesia. The participants were randomly allocated into two groups: the control group (Group NS) received an epidural injection of an equal amount of saline, while the study group (Group HY) received an epidural injection of 0.5 mg hydromorphone. We collected relevant data from electronic medical records to compare the differences between the two groups. The intervention group demonstrated lower pain scores at 4, 8, 12, 16, and 24 h compared to the control group (p < 0.001). Additionally, a higher number of patients in the control group required pain medication (7 (15.9%) compared to 2 (4.7%)). The time to first analgesia request in group NS was earlier than that in group HY (8.94 ± 1.27 h compared to 16.96 ± 3.38 h). The study group experienced higher rates of vomiting (P = 0.002) and itching (P < 0.001). However, there were no differences between the two groups in terms of urinary retention, dyskinesia, respiratory depression, dizziness, or neonatal feeding. The epidural injection of 0.5 mg hydromorphone proved to be effective in alleviating pain caused by maternal episiotomy and did not negatively affect neonatal feeding.Clinical trial registration: http://www.chictr.org.cn/usercenter.aspx identifier: ChiCTR2200064687.

Postpartum perineal pain and its association with sub-classified second-degree tears and perineal trauma-A follow-up of a randomized controlled trial.

INTRODUCTION: Postnatal perineal pain is prevalent following childbirth and can impact women both physically and emotionally. The aim of the study was to study the effect of collegial midwifery assistance on perineal pain and pain medication 1 month after birth and to investigate the associations between the type of tear and perineal pain, satisfaction with healing, and resumption of intercourse. MATERIAL AND METHODS: A follow-up questionnaire was sent 1 month postpartum to women with a first spontaneous vaginal birth participating in a randomized controlled trial (Oneplus trial). Data were collected from December 2019 to May 2020. Differences in perineal pain between women attended by one or two midwives were analyzed according to intention-to-treat using bivariate analyses. Associations between the type of tear and perineal pain, satisfaction with healing, and resumption of sexual intercourse were investigated using univariable and multivariable logistic regression. The category no tear/first-degree tear was compared separately to each of the other tear categories. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT03770962. RESULTS: Out of 2233 women, 1762 responded within 30-60 days postpartum. Of women in the no tear/first-degree tear category, 27.7% reported perineal pain during the past week, in contrast to women with OASI, where 64.2% reported perineal pain. Women with OASI experienced the highest odds of perineal pain (aOR 4.51, 95% CI 2.72-7.47) compared to those with no tear/first-degree tear, followed by women with major second-degree tears (aOR 1.87, 95% CI 1.45-2.41), women with an episiotomy (aOR 1.78, 95% CI 1.11-2.87), and those with minor second-degree tears (aOR 1.43, 95% CI 1.06-1.94). Women with episiotomy reported the highest odds ratios for dissatisfaction with tear healing (aOR 3.48, 95% CI 1.92-6.31). No significant differences in perineal pain and pain medication were observed between women allocated to collegial midwifery assistance and those allocated to standard care. CONCLUSIONS: Women with OASI reported the highest odds of perineal pain 30-60 days after birth compared to women with no tear or first-degree tear, followed by women with major second-degree tears. Women subjected to an episiotomy reported highest odds ratios of dissatisfaction with tear healing.

Case report: Perineal swelling: A rare case of scar endometriosis.

We report a rare case of episiotomy site scar endometriosis manifested as painful perineal swelling near the anus for 2 years affecting daily routine activity, especially during menses. A 33-year-old female, para 2 with both vaginal deliveries with last child birth 8 years back. A 2.5 × 3 cm firm, tender nodule was present on the posterior vulva at the right mediolateral episiotomy site. Trans-perineal and trans-anal ultrasound scan was done, anal sphincter involvement was ruled out and the nodule was excised with free margins. histopathology confirmed the diagnosis of scar endometriosis. The key takeaway from this case is endometriosis can present after 8 years of vaginal delivery. The timely diagnosis and treatment is necessary as delay may cause anal sphincter involvement or malignant transformation.

Levator Ani Muscle Avulsion After Vaginal Delivery Comparing Routine Versus Restrictive Episiotomy: A Pilot Study.

INTRODUCTION AND HYPOTHESIS: The objective was to compare the rate of levator ani muscle avulsion following vaginal birth after routine and restrictive episiotomy. METHODS: This study consists of two cohorts of pregnant women prospectively enrolled between September 2015 and December 2017 at a university hospital. The pregnant women were subject to a randomized controlled trial, in which participants received a restrictive episiotomy protocol versus a routine episiotomy protocol for vaginal delivery. Levator ani avulsion was evaluated by four-dimensional ultrasound screening. RESULTS: Sixty-one post-partum primipara women were enrolled in our study. Thirty-two women (52.5%) had undergone routine episiotomy whereas 29 women (47.5%) had gone through restrictive episiotomy. Right mediolateral episiotomies were performed in all cases. The rate of anal sphincter tear was 12.5% in the routine episiotomy group versus 13.8% in the restrictive episiotomy group (p = 1.00). Levator ani avulsion was detected in 9.4% of the routine episiotomy group (only on the right side) and in 10.3% of the restrictive episiotomy group (p = 1.00). No bilateral levator avulsion was detected in either of the groups. There were no statistical differences in the distances of the bladder neck descent, cystocele descent, uterine descent, rectocele descent, and the ballooning of the genital hiatus area between the groups. CONCLUSIONS: In our pilot study, there was no reduction of the rate of levator ani avulsion in women with restrictive episiotomy compared with routine episiotomy. There were no differences in pelvic floor ultrasound parameters between the two groups.

The impact of Reiki practice on episiotomy recovery and perineal pain: A randomized controlled study.

Energy therapies are complementary methods focused on revealing the existing energy and restoring the individual's (recipient's) energy. The aim of this study was to investigate the impact of Reiki practice applied to postpartum women who had spontaneous childbirth without instrumental delivery on postpartum episiotomy recovery and perineal pain. The research was randomized controlled at a hospital in pre-test post-test design. 86 postpartum women in total were included in the research, (n=40) in intervention group and (n=46) in control group. On the postpartum 1st day, 2nd day, 7th day and 14th day, episiotomy recovery of the intervention and control group was assessed with REEDA Scale and perineal pain was assessed with Short Form McGill Pain Questionnaire. The tree sessions of Reiki for 35-40 minutes were applied to intervention group on the postpartum 1st day, 2nd day and 7th day. (Clinical Trial Registry and Registration Number: NCT05486624). The REEDA Scale average oedema scores of the control group postpartum women were higher than intervention group. The control group had higher pain average than the intervention group. The Reiki applied to postpartum women who had spontaneous childbirth without instrumental delivery had a positive impact on episiotomy recovery due to its impact on oedema and it reduced perineal pain.

Les thérapies énergétiques sont des méthodes complémentaires axées sur la révélation de l'énergie existante et la restauration de l'énergie de l'individu (du destinataire). Le but de cette étude était d'étudier l'impact de la pratique du Reiki appliquée aux femmes en post-partum ayant eu un accouchement spontané sans accouchement instrumental sur la récupération par épisiotomie post-partum et les douleurs périnéales. La recherche a été randomisée et contrôlée dans un hôpital selon une conception pré-test et post-test. Au total, 86 femmes en post-partum ont été incluses dans la recherche, (n = 40) dans le groupe d'intervention et (n = 46) dans le groupe témoin. Les 1er, 2e, 7e et 14e jours post-partum, la récupération par épisiotomie du groupe d'intervention et du groupe témoin a été évaluée avec l'échelle REEDA et la douleur périnéale a été évaluée avec le questionnaire abrégé sur la douleur de McGill. Les séances d'arbres de Reiki pendant 35 à 40 minutes ont été appliquées au groupe d'intervention les 1er, 2e et 7e jours post-partum. (Registre des essais cliniques et numéro d'enregistrement : NCT05486624). Les scores moyens d'œdème sur l'échelle REEDA des femmes en post-partum du groupe témoin étaient plus élevés que ceux du groupe d'intervention. Le groupe témoin présentait une douleur moyenne plus élevée que le groupe d'intervention. Le Reiki appliqué aux femmes en post-partum ayant eu un accouchement spontané sans accouchement instrumental a eu un impact positif sur la récupération par épisiotomie en raison de son impact sur l'œdème et de la réduction des douleurs périnéales.

The effect of Camellia sinensis ointment on perineal pain and episiotomy wound healing in primiparous women: A triple-blind randomized clinical trial.

BACKGROUND AND OBJECTIVE: Episiotomy is one of the most commonly performed procedures in obstetrics. complications of episiotomy are pain, bleeding, infection, pain in the sitting position, and difficulty in taking care of the baby. This study aimed to investigate the effect of Camellia sinensis ointment on perineal pain and episiotomy wound healing in primiparous women. METHODS: This triple-blinded randomized clinical trial was conducted on 60 primiparous women who were referred to the maternity ward of Al-Hadi hospital in Shoushtar and Ganjovian hospital in Dezful, Iran, from 2020 to 2021. Participants were randomly assigned into two groups of intervention (Camellia sinensis extract ointment) and control (placebo) with a follow-up of 14 days. REEDA scale (redness, edema, ecchymosis, discharge, and approximation) was used to measure wound healing and the Visual Analog Scale (VAS) was used to measure the pain intensity. RESULTS: There was no significant difference between two groups before intervention in terms of sociodemographic characteristics, pain intensity, and episiotomy wound status. Scores of pain intensity and wound healing reduced on days 7, 10, and 14 post-intervention in the intervention group compared to placebo. There was a significant decrease between the groups of intervention and control in terms of the mean score of pain intensity (VAS scale) on day 10 (1.33 ± 0.71, 1.77 ± 0.93) and day 14 (0.73 ± 0.74, 1.13 ± 0.81) post-intervention (P < 0.05). Also, on day 14 post-intervention, there was a significant decrease between the groups of intervention and control in terms of the mean score of episiotomy wound healing (REEDA index) (0.53 ± 0.77, 1.77 ± 1.46) (P < 0.05). The GLM test was applied for repeated measures. REEDA index and VAS scale changed during different times (time-variable) (p < .001). But, the studied groups (group variable) and the studied groups (interaction effect of group * time) did not affect the changes in the REEDA index (p = .292, p = .306) and VAS scale (p = .47) during different times. CONCLUSION: Our study showed that Camellia sinensis extract ointment has a small effect on the healing process and pain reduction of episiotomy wounds. to confirm its effect, a study with a larger sample size should be conducted. TRIAL REGISTRATION: This trial was registered in the Iranian Registry of Clinical Trials on 04/10/2019 with the IRCT ID: IRCT20190804044428N1. Participants were enrolled between 11 April 2020 and 20 January 2021. URL of registry: https://en.irct.ir/trial/41326.

Pulsating electromagnetic fields for perineal lacerations and surgical wounds healing in the postpartum: a pilot study.

PURPOSE: The aim of our study was to assess the possible benefits of Therapeutic Magnetic Resonance (TMR) in the treatment of spontaneous perineal lacerations and episiotomies in the postpartum. METHODS: We performed a prospective, non-pharmacologic, non-profit, monocentric interventional study on women who had a spontaneous laceration and/or an episiotomy at delivery. The TMR device treatment was accepted by 52 women, while 120 women underwent standard care. Patients were visited 1 day postpartum, before starting the treatment; then a follow-up visit was performed at 3 weeks, 5 weeks, and 3 months after delivery. The main endpoint was the time required for complete healing of the laceration and/or the episiotomy. Secondary endpoints were the prevalence of dehiscence, infections, urinary discomfort, urinary leakage, and the quality of restoration of sexual function. RESULTS: In the treatment group the REEDA score was significantly better both at 3- and 5-weeks postpartum follow-up. At 3 weeks and 5 weeks postpartum, we observed a significantly better outcome in the treatment group for all subjective complaints and perineal complications associated with lacerations and episiotomies. The percentage of patients who scored above the cutoff for sexual dysfunction was significantly better in the treatment group (83.3%) than in the control group (31.8%) (p < 0.001). CONCLUSIONS: With this pilot study, we introduced low dose Pulsating Electromagnetic Fields (PEMFs) as a novel conservative and not pharmacological approach to reduce complications of perineal lesions. Our results demonstrated to significantly improve perineal wound healing and to ameliorate the sexual function in the postpartum.

Comparison of photobiomodulation with cryotherapy in the immediate postpartum period of parturients with grade I, grade II lacerations and/or episiotomy in reducing perineal and vulvar and edema: A randomized clinical trial.

INTRODUCTION: Vaginal delivery has several benefits for the parturient; however, during labor, some injuries, such as lacerations and/or episiotomy, can occur. Perineal pain may occur in the puerperium and can be aggravated in cases of perineal injury during childbirth, potentially impacting the physical and emotional aspects of the parturient. For this reason, it is necessary to use techniques that can relieve pain and edema in the immediate postpartum period, directly influencing recovery. OBJECTIVE: To compare the reduction of pain and improvement in healing using two techniques, namely photobiomodulation and cryotherapy, performed in the immediate postpartum period of up to 12 h, in parturients who suffered grade I and II lacerations and/or episiotomy. METHODS: Data collection was carried out through an evaluation questionnaire. Photobiomodulation was applied using the red and infrared laser from the DMC brand. The EVA and McGill scales were used for pain assessment, and the REEDA scale was used for the evaluation of edema and healing. RESULTS: The techniques were evaluated and applied to 56 patients, with 28 in each group (cryotherapy and LBI). Patients who received photobiomodulation showed superior improvement compared to cryotherapy. In the immediate postpartum period, there was a greater reduction in pain in favor of photobiomodulation (p = 0.008); and after 24 h, the difference was even more significant (p < 0.001).

The Effect of Virtual Reality Application on Pain and Anxiety During Episiotomy Repair: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION AND HYPOTHESIS: There is a rising trend among women towards nonpharmacological approaches owing to their minimally invasive nature and limited adverse effects. Virtual reality (VR) has recently gained popularity as a new technology for reducing pain and anxiety in medical settings. Our research sought to investigate the impact of VR on pain and anxiety levels while undergoing episiotomy repair. METHODS: A comprehensive search was carried out across PubMed, Scopus, Cochrane Library, and ISI Web of Science to find relevant randomized clinical trials (RCTs) up to January 2024. These trials investigated the use of VR as a treatment during episiotomy repair compared with a control group that did not receive VR intervention. Meta-analysis was performed using Review Manager software to analyze the data collected. Our primary outcomes were pain scores reported during and after episiotomy repair measured by a visual analog scale. Secondary outcomes analyzed included anxiety scores during and after the procedure, as well as the duration of episiotomy repair. RESULTS: Seven RCTs, involving 578 patients, met the inclusion criteria. VR resulted in a significant reduction in pain scores both during and after episiotomy repair (p < 0.001). Additionally, anxiety levels during and after the procedure were significantly reduced in the VR group compared with the control group. Moreover, the duration of episiotomy repair was significantly shorter in the VR group. CONCLUSION: Using VR has proven to be an effective technique in reducing pain and anxiety during and after episiotomy repair, as well as potentially speeding up the procedure.

The association between BMI, episiotomy, and obstetric anal sphincter injuries (OASIS) in singleton vaginal deliveries.

OBJECTIVE: Prevalence of obesity in reproductive age and pregnant women has been on the rise during the past several decades. The relationship between body mass index (BMI) and obstetric anal sphincter injuries (OASIS) or episiotomy has not yet been thoroughly investigated. The objective of this study was to shed light on this issue. METHODS: This retrospective cohort study was performed using electronic database of an obstetrics department at a university-affiliated tertiary medical center. All spontaneous singleton vaginal deliveries at term between January 2015 and December 2021 were included. The primary outcome was the incidence of OASIS (third- and fourth-degree perineal tears) and obesity. These were compared across three BMI categories: normal (BMI below 25 kg/m2), overweight (BMI 25.0-29.9 kg/m2), and obesity (BMI of 30 kg/m2 and over). RESULTS: Of the overall 13,932 spontaneous vaginal deliveries identified, 34.7 % had BMI in the normal range, 43.1 % were overweight, and 25.4 % were obese. Multivariate analysis demonstrated lower rates of OASIS in obese (OR 0.2, 95 %CI 0.04-0.9) and in overweight (OR 0.3, 95 %CI 0.1-0.99) women, as compared to the normal-weight cohort. In addition, lower rates of episiotomy were noted in the obese cohort (OR 0.7, 95 %CI 0.6-0.8). CONCLUSIONS: Decreased incidence of OASIS was noted in women with obesity, in conjunction with lower use of episiotomy. These findings imply that obstetrics clinics might consider a more conservative approach to episiotomy in obese patients.

Lateral episiotomy or no episiotomy in vacuum assisted delivery in nulliparous women (EVA): multicentre, open label, randomised controlled trial.

OBJECTIVE: To assess the effect of lateral episiotomy, compared with no episiotomy, on obstetric anal sphincter injury in nulliparous women requiring vacuum extraction. DESIGN: A multicentre, open label, randomised controlled trial. SETTING: Eight hospitals in Sweden, 2017-23. PARTICIPANTS: 717 nulliparous women with a single live fetus of 34 gestational weeks or more, requiring vacuum extraction were randomly assigned (1:1) to lateral episiotomy or no episiotomy using sealed opaque envelopes. Randomisation was stratified by study site. INTERVENTION: A standardised lateral episiotomy was performed during the vacuum extraction, at crowning of the fetal head, starting 1-3 cm from the posterior fourchette, at a 60° (45-80°) angle from the midline, and 4 cm (3-5 cm) long. The comparison was no episiotomy unless considered indispensable. MAIN OUTCOME MEASURES: The primary outcome of the episiotomy in vacuum assisted delivery (EVA) trial was obstetric anal sphincter injury, clinically diagnosed by combined visual inspection and digital rectal and vaginal examination. The primary analysis used a modified intention-to-treat population that included all consenting women with attempted or successful vacuum extraction. As a result of an interim analysis at significance level P<0.01, the primary endpoint was tested at 4% significance level with accompanying 96% confidence interval (CI). RESULTS: From 1 July 2017 to 15 February 2023, 717 women were randomly assigned: 354 (49%) to lateral episiotomy and 363 (51%) to no episiotomy. Before vacuum extraction attempt, one woman withdrew consent and 14 had a spontaneous birth, leaving 702 for the primary analysis. In the intervention group, 21 (6%) of 344 women sustained obstetric anal sphincter injury, compared with 47 (13%) of 358 women in the comparison group (P=0.002). The risk difference was -7.0% (96% CI -11.7% to -2.5%). The risk ratio adjusted for site was 0.47 (96% CI 0.23 to 0.97) and unadjusted risk ratio was 0.46 (0.28 to 0.78). No significant differences were noted between groups in postpartum pain, blood loss, neonatal outcomes, or total adverse events, but the intervention group had more wound infections and dehiscence. CONCLUSIONS: Lateral episiotomy can be recommended for nulliparous women requiring vacuum extraction to significantly reduce the risk of obstetric anal sphincter injury.

The impact of selective episiotomy on maternal short-term morbidity: a retrospective study.

BACKGROUND: The aim is to investigate the risk of short-term maternal morbidity caused by the selective clinical use of episiotomy (rate < 0.02), and to compare the risk of severe perineal tears with the statewide risk. METHODS: In this retrospective cohort study, we investigated the effect of selective episiotomy on the risk of severe perineal tears and blood loss in singleton term deliveries, using propensity scores with inverse probability weighting. RESULTS: This study included 10992 women who delivered vaginally between 2008-2018. Episiotomy was performed in 171 patients (1.55%), three of whom (1.75%) experienced severe perineal tears compared to 156 (1.44%) in the control cohort. The adjusted odds ratio of severe perineal tears was 2.06 (95% confidence interval [CI]: 0.51, 8.19 with 0.3 p value). Multivariate linear regression showed that episiotomy increased blood loss by 96.3 ml (95% CI: 6.4, 186.2 with 0.03 p value). Episiotomy was performed in 23% (95% CI: 0.228, 0.23) of vaginal deliveries in the state of Hessen, with a risk of severe perineal tears of 0.0143 (95% CI: 0.0139, 0.0147) compared to 0.0145 (95% CI: 0.0123, 0.0168) in our entire cohort. CONCLUSIONS: Selective use of episiotomy does not increase the risk of higher-grade perineal tears. However, it may be associated with maternal morbidity in terms of increased blood loss.

An episiotomy is a cut between the vagina and the anus that may be performed by an obstetrician during childbirth and can result in increased blood loss or severe birth tears. In this study, we investigated the risks of both bleeding and severe tears caused by a highly selective local practice of episiotomies below 2% and compared the results with statewide data. The study included 10992 women who delivered between 2008­2018, 171 of whom underwent episiotomies according to the hospital's protocols. Having an episiotomy did not increase the likelihood of severe birthing tears but was associated with an increase in estimated blood loss. Therefore, although highly selective use of episiotomy is unlikely to cause more severe tears, it has the potential to worsen the mother's health by increasing blood loss.

Randomized controlled trial of the effectiveness of olive and black seed oil combination on pain intensity and episiotomy wound healing in primiparous women: A study protocol.

BACKGROUND: Episiotomy is associated with side effects, such as pain and wound infection. Additionally, discomfort after episiotomy affects the quality of life of both the mother and the baby. Medicinal herbs are one alternative method for the treatment of episiotomy wounds. This study will investigate the effectiveness of the combination of olive and black seed oil on pain intensity and the healing of episiotomy wounds in primiparous women. METHODS: This randomized clinical trial will be conducted on primiparous women who have had a normal delivery with an episiotomy. There are 3 groups in this study: one group will receive a combination of olive oil and black seed oil, another group will receive olive oil alone, and the use of oils will start 24 hours after delivery. Ten drops will be applied topically 3 times a day for 10 days. The third group (control) will receive only routine care. Data will be collected through a demographic characteristics questionnaire, REEDA (Redness, Edema, Ecchymosis, Discharge, and Approximation) Scale, and Visual Analog Scale. To determine and compare the effects of pharmaceutical interventions on pain intensity and episiotomy wound healing in the groups, an analysis of variance (ANOVA) test with repeated measurements will be used with SPSS version 22. DISCUSSION: The results of this study will show the effects of a combination of olive and black seed oil, as well as olive oil alone, on pain intensity and episiotomy wound healing in primiparous women. The positive effects observed in this trial with these oils could be valuable for women who have undergone an episiotomy.

Comparative study of postpartum sexual function: Second-degree tears versus episiotomy outcomes.

PURPOSE: The effects of episiotomy and second-degree tears on postpartum sexual function are key areas of enquiry in women's health research. Episiotomy and second-degree tears are common procedures and injuries that occur during childbirth. Understanding their impact on post-childbirth sexuality is crucial to women's overall well-being. This study aimed to examine the relationship between episiotomy, second-degree tears, and post childbirth sexuality. METHODS: A cross-sectional design was employed, including 83 women who gave birth to Cáceres in 2017. Participants were evaluated based on sociodemographic and sexual health factors. RESULTS: No significant differences were found in dyspareunia or sexual function between women who underwent episiotomies and those with second-degree tears. However, women who underwent episiotomies waited longer before resuming sexual activity after childbirth. Factors such as age, number of previous births, employment status, educational level, and breastfeeding status affected the timing and frequency of postpartum sexual activity. CONCLUSION: Dyspareunia negatively affects various aspects of sexual function. When comparing episiotomy and second-degree tears, their impacts on postpartum sexual function were similar. However, episiotomy delays the resumption of sexual activity. Sociodemographic factors significantly influence postpartum sexual health. These findings highlight the importance of individualised interventions and support for new mothers during the postpartum period to address potential sexual health concerns.

Midwives' approach to the prevention and repair of obstetric perineal trauma in Spain.

AIM: Different clinical practice guidelines include recommendations on how to prevent and repair obstetric perineal trauma, as well as the use of episiotomy. To evaluate the variability in midwives' professional practices for preventing and repairing perineal trauma, as well as the professional factors that may be associated with the restrictive use of episiotomy. DESIGN: Observational cross-sectional study. METHODS: Three hundred five midwives completed an anonymous questionnaire developed by the authors and distributed across various midwifery scientific societies. The main outcomes measured were the frequencies of adopting specific practices related to perineal injury prevention and repair, episiotomy technique and restrictive episiotomy use (<10%). Odds ratios (OR) and adjusted odds ratios (aOR) with 95% confidence intervals were estimated. RESULTS: Intrapartum perineal massage was not normally used by 253 (83%) of midwives, and 186 (61%) applied compresses soaked in warm water to the perineum. Regarding episiotomy, there was a great deal of variability, noting that 129 (42.3%) adopted a restrictive use of this procedure, 125 (41%) performed it between 10% and 20%, while 51 midwives (16.7%) performed it in more than 20% of cases. In addition, 165 (54.1%) midwives followed an incision angle of 60º. Concerning tears, 155 (50.8%) usually sutured first-degree tears and 273 (89.5%) always sutured second-degree tears. Midwives attending home births (aOR = 6.5; 95% CI: 2.69-15.69), working at a teaching hospital (aOR = 3.69; 95% CI: 1.39-9.84), and the ones who recently completed their professional training (aOR = 3.58; 95% CI: 1.46-8.79) were significantly more likely to adopt a restrictive use of episiotomy. CONCLUSIONS: There is a significant variability in Spanish midwives' practices for preventing and repairing perineal tears. Moreover, the restrictive use of episiotomy is associated with midwives attending home births, working in teaching hospitals and having recent professional training.
