title: Factors affecting the rates of caesarean sections in cases with premature rupture of membranes (PROM) at term.
abstract: The aim of this retrospective study was to investigate the factors affecting the rates of caesarean section in cases with premature rupture of membranes (PROM) in term pregnancies. Eighty-two term PROM patients who presented to Turgut Ozal University and Erzurum Nene Hatun Hospitals between 2012 and 2014 were included. The effects of demographics, nulliparity, active-latent phase durations, presence of meconium and chorioamnionitis, requirement of oxytocin and cervical dilation at the initial examination on C/S rates were assessed. The C/S rates were changed with the duration of active period and the duration of latent period. It was found that the presence of cervical dilation at the initial examination significantly reduced the risk for progress to C/S at a rate of 87.5%. C/S rates did not change with other variables. We conclude that the factors increasing the risk for C/S in PROM at term group are not different from the non-term PROM. Impact statement The aim of this retrospective study was to investigate the factors affecting the rates of caesarean section (C/S) in cases with premature rupture of membranes (PROM) in term pregnancies. The C/S rates were changed with the duration of active period and the duration of latent period. It was found that the presence of cervical dilation at the initial examination significantly reduced the risk for progress to C/S at a rate of 87.5%. We conclude that the factors increasing the risk for C/S in PROM at term group, are not different from the non-term PROM groups. Currently, the PROM is considered the start of a pathological process in both term and preterm pregnancies and also considered to increase the rates of caesarean sections. Studies on the management of PROM at term have concentrated rather on whether to intervene for accelerating the labour or spontaneous monitorisation. As found by the studies like this one in the literature, the factors having an impact on C/S rates in the cases of PROM at term are similar to those of non-PROM patients at term, may prevent clinicians from taking an invasive or aggressive approach towards the cases of PROM at term.
