Abstract

Background: One of the causes contributing to the high maternal mortality rate in Indonesia is postpartum hemorrhage, which can be the consequence of perineal rupture. Perineal rupture can happen spontaneously in normal vaginal delivery or worsen after episiotomy, induction of labor, vacuum and forceps delivery. This study aims to know the prevalence and characteristics of perineal rupture so that it can be used as data to make policy guidelines for preventing and reducing the incidence of perineal rupture. Methods: This is a retrospective descriptive study analyzing secondary data collected from Sanglah General Hospital and nine other Regional Hospitals from January 2018 until December 2019. The data analysis technique used is a univariable analysis by calculating the frequency distribution and proportion to determine the prevalence and characteristics of the research subjects. Data were analyzed using SPSS version 20 for Windows. Results: There are 8,178 cases of vaginal delivery, 6,191 cases (75.70%) with perineal rupture and 1,987 cases (24.30%) without perineal rupture. Perineal rupture is most often found in women < 20 years old (82.66%), primigravida (81.76%), preterm gestational age (78.23%), the baby with birth weight > 4,000 grams (94.26%), underweight mother (87.50%), and women with assisted delivery by vacuum or forceps (100.00%).  Conclusion: The Prevalence of perineal rupture in this study is 75.70%, with the most characteristics being women < 20 years old, primigravida, preterm gestational age, macrosomia baby, normal IMT, assisted vaginal delivery.
