The aim of this study is to compare the effects of oxytocin alone and oxytocin in combination with intravenous and oral propranolol on labor progression. This study will be done as a randomized clinical trial study in Sanandaj Besat Hospital. Total of 123 pregnant women who had inclusion criteria divided into three groups using triplex random blocks. The sample size in each group is 41 cases. Inclusion criteria included: 38 to 41 weeks gestational age, nuliparity, singleton, cephalic presentation, fetal heart rate 120 to 160 beats per minute, approximate weight of 2,500 to 4,000 gr (confirmed by examination or ultrasound), the maternal heart rate between 60 to 130 beats per minute, intact membranes and bishop score equal to or less than 5 . Exclusion criteria included: CPD, any history of previous surgery on the uterus, fetal distress, the risk of macrosomia or polyhydramnius, SBP≤100, PR≤60, PR≥130 min, any history of cardiopulmonary disease, metabolic disease of mother or taking medicine for any illness by mother. In the oxytocin alone group, use of oxytocin will start at 2mIU/min and every 15 minutes the same amount will added to create a good contraction (3 contractions in 10 minutes) this continues maximally up to 8 hours and 30 mlU. In entering the active phase of labor induction continues to delivery, in case of no entry to the active phase (3- 4 cm Dilation) stop induction after 8 hours and continues it the next day. In the absence of response to induction the second day will be cesarean section. In the oxytocin with intravenous propranolol group, concurrent with the induction 2 mg propranolol will infuse intravenously and slowly and two hours after administration, patient will be examined vaginally. If after two hours cervical dilation did not change propranolol dose repeated just for another time and induction continues. Patient will be controlled and decision will be made to continue induction to delivery or termination of pregnancy with cesarean section. Patient`s blood pressure every hour and fetal heart rate every 15 minutes will be controlled. In the oxytocin with oral propranolol group, from beginning of induction 20 mg propranolol administered orally, If after four hours cervical dilation did not change propranolol dose repeated just for another time and induction continues. Patient will be controlled and decision will be made to continue induction to delivery or termination of pregnancy with cesarean section.
