In recent years, the frequency of induced labor (IOL) has increased. The main objective of this study is to investigate and analyze the indications and perinatal outcomes of IOLs performed at San Juan University Hospital, and to investigate the behavior of factors described as predictors of the outcome of induction in our environment.
This retrospective descriptive study was carried out by systematically reviewing of the corresponding medical records for all pregnancies that ended with medical intervention during 2019.
The study population consisted of 342 IOLs (34,2%) and 93 elective cesarean sections (9,3%). The most frequent indication for elective c-section was abnormal fetal presentation (36,6%) whilst the most common indication for IOL was rupture of membranes. 71,3% of IOLs were started with oxytocin while on the contrary, 28,7% were induced with prostaglandins. Of the latter, 66,3% required administration of oxytocin to begin labor. Prostaglandin IOLs were more frequently used in cases of a gestational age of 41 weeks or more, nulliparity, previous c-section without prior vaginal delivery, female fetal sex, and Bishop score on admission of 4 or less. The c-section rate in induced births was 29,8% whereas the rate for instrumental births was 13,2%.
In conclusion, the different frequency rates analyzed throughout the study agree with those of other Spanish studies. The study of predictive factors coincides likewise with what other authors have argued, finding that risk factors for c-section are advanced gestational age, nulliparity, having a previous cesarean section, and elevated estimated fetal weight (p<0,05).
