IRCT20180411039267N3 IRCT 2019-07-13 Tabriz University of Medical Sciences Effect of ephedrine on fetal and neonatal heart rate in emergency cesarean delivery due to fetal bradycardia A study of effect of prophylactic intravenous ephedrine on fetal and neonatal heart rate in emergency cesarean delivery due to fetal bradycardia 2019-06-01 anticipated 96 Complete https://irct.ir/trial/32025 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: The cases will be randomly divided into two groups of 48 people in the study group and 48 people in the control group using random numbers table. In the event of odd, they would be placed in the ephedrine group and in the event of even, they would be placed in the placebo group, Blinding description: The administration of anesthesia and serum before and during anesthesia is performed by an anesthesiologist and anesthesia technician. So that one ml of bolus intravenous ephedrine (equivalent to 10 mg) is injected into the study group and one ml of sodium chloride 0.9% as a placebo is injected into the placebo group. Then, all data will be collected and recorded in the checklist by an other anesthesiologist who is unaware of the injected drug type and the division of the groups and is not in charge of anesthesia management. Pregnant women undergoing cesarean section are also unaware of the division of the groups. 3 fetal bradycardia, prophylactic intravenous ephedrine, emergency cesarean delivery. Intervention 1: Intervention group: In 48 pregnant women with fetal bradycardia, as soon as mother's arrival into the operating room and after initial monitoring, one ml of intravenous ephedrine equivalent to 10 mg will be injected to the mother and its effect on the fetal and neonatal heart rate will be examined. Intervention 2: Control group: In 48 pregnant women with fetal bradycardia, as soon as mother's arrival into the operating room and after initial monitoring, one ml of intravenous sodium chloride 0.9% as a placebo will be injected to the mother and its effect on the fetal and neonatal heart rate will be examined. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is There is no more information.
