Effect Of Intravenous Hyoscine -N-Butyl Bromide In Management Of Prolonged Labor In Nulliparous
Overview
Women will be admitted when active phase of labour starts defined as the presence of at least three regular uterine contractions over 10 minutes with cervical dilatation four centimeters with cervical effacement not less than 50% and no progress of labor for 2 hours or more. Amniotomy was done in those with intact membrane and continuous electronic fetal monitoring was done. Women with prolonged labor after these measures were randomly divided using automated web-based randomization system into 2 equal groups. Group I included 50 women received 40mg HBB (Buscopan, Memphis Co, Giza, Egypt) intravenous bolus injection. Group II included 50 women received 2 ml of normal saline. The obstetrician, participants and outcome assessor were all blinded to the group assignment. Labor will be monitored by Vaginal examination every two hours. The duration of the first stage was calculated from the time of cervical dilatation of three to four centimeters in active labor until a fully dilated cervix was observed.
