Abstract
Objective: To compare maternal and neonatal outcomes by forceps vaginal delivery versus cesarean delivery during the second stage of labor. Methods: We conducted a retrospective cohort study in a large tertiary maternity center in Shanghai, China through 2007-2016. A total of 7046 women carrying a singleton term nonanomalous fetus with vertex presentation who underwent forceps vaginal delivery, or cesarean delivery from a low station in the second stage of labor were included. Results: Of the 7046 women, 6265 underwent forceps and 781 underwent second stage cesarean delivery. Forceps were associated with lower frequency of maternal infection (2.2 versus 4.7%), but higher incidence of mild postpartum hemorrhage (PPH) (4.3 versus 0.6%). When the procedures were performed for fetal indication, forceps were associated with lower frequency of the composite of perinatal mortality and/or hypoxic ischemic encephalopathy (HIE) (0.5 versus 1.9%; adjusted odds ratio (aOR), 0.24; 95% CI: 0.08-0.75), and also shorter decision to delivery interval (12.3 ± 3.5 versus 19.1 ± 5.0 min). The neonatal infection rate was higher in the forceps group (3.9 versus 2.0%). There were no differences in other neonatal outcomes including birth trauma.Conclusions: In women who had a need for intervention during the second stage with a station of +2 or below, forceps were associated with a lower frequency of maternal infection but a higher rate of PPH. Deliveries performed for nonreassuring status were accomplished faster by forceps and were associated with a lower frequency of the composite of perinatal mortality and HIE.
