Adverse effects of these methods include vaginal bleeding after examination and maternal discomfort. This process releases endogenous prostaglandins, leading to cervical ripening and initiation of uterine contractions. Membrane sweeping is performed during a vaginal exam, during which the examiner inserts one or two fingers inside the cervical canal and rotates them in a circular motion to separate the lower part of the amniotic membranes from the lower uterine wall. Mechanical labor induction methods include osmotic dilators, transcervical Foley catheters, double-balloon catheters, and membrane sweeping (stripping). Both medical drugs used for labor induction have adverse effects, such as uterine hyperstimulation and intrapartum fetal distress, especially when combined with other mechanical methods for induction. Oxytocin infusion is associated with initiating rhythmic uterine contractions and is usually used in patients with a higher cervical score. Various methods for labor induction exist, including prostaglandins, which play a key role in cervical ripening and initiating uterine contractions in both ripened and un-ripened cervixes. This depends on various factors, including the accuracy of gestational age calculation, previous obstetric history, estimated fetal weight, cervical score, and maternal preference. Inducing labor is a recognized intervention to improve outcomes and reduce complications related to post-term pregnancy, but there are ongoing debates regarding the need and timing of labor induction. Maternal complications can include prolonged and obstructed labor, increased risk of operative vaginal delivery and cesarean section, genital tract trauma and hemorrhage, and heightened maternal anxiety. Post-term pregnancy is associated with fetal complications such as oligohydramnios, intrapartum fetal asphyxia, meconium aspiration, stillbirth, and trauma during labor (such as shoulder dystocia). ![]() Risk factors for post-term pregnancy include being a first-time mother, having had a previous post-term pregnancy, and congenital fetal malformations (such as anencephaly). While the mean length of a typical pregnancy is around 40 weeks, calculated from the first day of the last menstrual period, estimating gestational age using first-trimester ultrasound and measuring the crown-rump length (CRL) or head circumference when the CRL is greater than 84 mm is more accurate. Fetal growth beyond this point is associated with reduced placental reserve and blood supply, leading to increased fetal and neonatal morbidity and mortality. A large, controlled study is required to compare its benefits over other methods of induction of labor.Ī pregnancy that continues beyond 42 weeks gestation is a post-term pregnancy, which poses significant risks to both the mother and her child. Additionally, no maternal and/or fetal deaths were reported. Membrane sweeping to induce labor has a high success rate, and it can be safe for both the mother and the baby, as it is associated with a low rate of maternal and fetal complications. Seven neonates (4.8%) were admitted to the NICU. One hundred thirty-three (90.5%) had Apgar scores <7, eight (5.4%) had Apgar scores under five, and six (4.1%) had Apgar scores of five to six. Thirteen (8.8%) neonates weighed less than 2.5 kg, and eight (5.4%) weighed more than 3.5 kg. All neonates were alive, and most (n=126 85.8%) birth weights ranged from 2.5 kg to 3.5 kg. Most of the women in the study (n=138 93.9%) had no complications, seven (4.8%) had postpartum hemorrhage, one (0.7%) had sepsis, and one (0.7%) was admitted to the intensive care unit. Membrane sweeping induced labor in 127 postdate women (86.4%). Data were collected through patient interviews using a specially designed questionnaire and analyzed using Statistical Package for Social Sciences (SPSS®) software for Windows, Version 26.0 (Armonk, NY: IBM Corp.), We recorded the number of sweeps needed, sweeping-to-delivery interval, mode of delivery, maternal outcome, and fetal outcome (including birth weight, Apgar score at delivery, and the need for neonatal intensive care unit admission ). This prospective descriptive cross-sectional study conducted at Alhashesa Teaching Hospital, Alhashesa, Sudan, between May and October 2022 included all pregnant women at 40 or more weeks of gestation who underwent membrane sweeping to induce labor. This study aimed to determine the success rate and the outcome of membrane sweeping in postdate pregnant women in Alhasahesa Teaching Hospital. This produces hormones that promote effacement and dilatation, potentially promoting labor. ![]() Membrane sweeping is a mechanical technique by which a clinician inserts one or two fingers into the cervix and detaches the inferior pole of the membranes from the lower uterine segment using a continuous circular sweeping motion.
