The relationship between the Bishops score at admission and deliver outcomes in nulliparous women in 29 Bahman hospital, Tabriz

The aim of care at birth is having a healthy mother and baby and achieving a successful vaginal delivery. Since unripe cervix leads to increased cesarean rate and causing maternal and neonatal complications, this study was performed with aim to investigate the relationship between Bishop Score at admission and delivery outcomes in nulliparous women.
This descriptive and analytic study was performed on 300 nulliparous women referring to 29 Bahman Hospital, Tabriz in 2015. Data collection tools included a checklist of individual characteristics, obstetric history, information about Bishop Score at admission, and delivery outcomes. Data were collected through observation of delivery course and studying the contents of the patient’s file. Data was analyzed by SPSS statistical software (version 21) and correlation test. P
There was significant relation between Bishop Score and duration of the first and second stage of labor (P=0.0001), duration of uterine contractions in the first stage of labor (P=0.001), abnormal fetal heart rate pattern in the first and second stage of labor (P=0.0001), using oxytocin (P=0.0001), frequency of using oxytocin (P=0.0001), the distance between the amniotomi or rupture of membranes and delivery (P=0.0001), doing episiotomy (P=0.01), pressure on the fundus during delivery (P=0.001), excessive postpartum hemorrhage (P=0.014), first minute Apgar (p=0.014), and measures taken on newborn (P=0.009). Mode of delivery (P=0.0001) was significantly related to Bishop Score at admission, so that 41 cases (31.1%) with Bishop Score ≤4 and 6 (3.6%) with Bishop Score >4 needed to perform cesarean.
Low bishop score and unripe cervix lead to an increase in adverse delivery outcomes and according to the results of this study, proceedings must be done for cervical ripening to promote Bishop score.
