The episiotomy angle and length can influence probability of anal sphincter trauma, ease of delivery and post-delivery recovery in variable ways. We hypothesize that a universal measure of angle (60°) and length might not be ideal for all women. This aim of this cohort study was to establish association of episiotomy trigonometric characteristics (length and angle) with antepartum, intrapartum and postpartum factors.</div></div><div><h3>Material &amp; methods</h3><div>A total of 504 pregnant women who delivered with an episiotomy after 34 weeks of gestation were included. Antenatal, intrapartum, and postpartum variables were collated. These women were examined for episiotomy length, angle, signs of infection/inflammation and pain using Visual Analogue Scale (VAS). All of them were followed up till they were discharged frm the hospital.</div></div><div><h3>Results</h3><div>A smaller episiotomy angle (&lt;15°) was associated with significantly higher VAS score as compared to angle 35°-40°. We observed that as birth weight increases, mean episiotomy length and angle progressively increases. Longer head circumference was associated with longer length of episiotomies (p &lt; 0.01). Instrumental deliveries were associated with higher length and angle of episiotomy.</div></div><div><h3>Conclusion</h3><div>We observed a relationship of trigonometric characteristics of episiotomy with variables like birth weight and HC. We feel the angle and length of episiotomy cannot be defined as a universal constant. It depends of maternal and fetal variables.

The frequency of intra-amniotic infection/inflammation is higher in extremely sPTB (&lt;28 weeks) and causes long-term cognitive impairments, such as cerebral palsy and mental retardation. The rate of intra-amniotic superinfections, such as <em>Ureaplasma</em>/<em>Mycoplasma</em> and bacteria, is high in sPTB &lt; 27 weeks of gestation. Obstetrical strategies based on accurate information on intra-amniotic infection/inflammation are needed to prevent sPTB (particularly extremely sPTB) and improve the long-term prognosis of preterm infants. Our PCR method, which is sensitive and free from false positives, accurately identifies whether intra-amniotic infection is present. Appropriate antibiotic therapy against intra-amniotic infection (macrolides against <em>Ureaplasma</em>/<em>Mycoplasma</em> and beta-lactams against bacteria) in preterm labor (PTL) cases effectively prolongs the gestational period by 4 weeks. In contrast, the use of antibiotics shortens the gestational period in cases without intra-amniotic infection. We previously reported that 17-alpha-hydroxyprogesterone caproate (17OHP-C) effectively prolonged pregnancy by 4 weeks in PTL cases with mild intra-amniotic inflammation, but not in those with severe intra-amniotic inflammation. Treatment strategies based on accurate intra-amniotic information is expected to prolong pregnancy. However, obstetrical interventions are limited once severe clinical symptoms appear. In addition to the use of drugs to control uterine contractions, antibiotics and/or 17OHP-C may be necessary in the treatment of PTL cases following the accurate assessment of intrauterine infection and/or inflammation is confirmed.</div></div>","PeriodicalId":37085,"journal":{"name":"European Journal of Obstetrics and Gynecology and Reproductive Biology: X","volume":"27 ","pages":"Article 100408"},"PeriodicalIF":1.5,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144290482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
