Abstract

Dr. Murat ÇAĞAN, The change in the method of delivery over years and the Robson Ten Group Classification System, Hacettepe University Faculty of Medicine Department of Obstetrics and Gynecology, Graduation Thesis, 2017, Ankara.The aim of this study is to demonstrate the changes in the ratios of vaginal delivery, operative vaginal delivery and caesarean section (CS) in Hacettepe University Faculty of Medicine. The data of pregnant women who delivered in Hacettepe University Hospitals in 1976, 1986, 1996, 2006 and 2016 were evaluated retrospectively with “Robson Ten Group Classification System” (TGCS). The descriptive statistical analysis of the data necessary for the Robson Ten-group Classification System such as parity, onset of the labor, duration of pregnancy, fetal presentation, number of fetuses and indications for caesarean delivery was performed. The ratio of CS was increased and the ratio of opertive vaginal deliveries was decreased over the years. The ratio of CS was found to be 11.4%, 19.2%, 44.7%, 69.3% and 77.9% for years 1976, 1986, 1996, 2006, and 2016, respectively. CS has become preferred method of delivery for multiple pregnancies and breech malpresantations over years. It was shown that Group 5 (of those with previous uterine surgery) was the greatest contributor to the increased caesarean ratios, the relative contributions of groups with lower-risk for caesarean delivery (Groups 1 and 3) were decreased, and the relative contributions of Groups 2 and 4 (of those with induction or caesarean performed prior to labor on nullipara/multipara) were increased, thus increasing the caesarean ratios. The most common indications of caesarean delivery were found to be prior caesarean delivery, dystocia and fetal distress in our study.
