Effect of B-ultrasound combined with intravenous terbutaline sulfate for external cephalic version / 实用医学杂志

ABSTRACT

Objective To investigate the effect of ultrasound combined with intravenous terbutaline sulfate for external cephalic version and the impact of this therapy on maternal and neonatal complications.Methods 126 singleton pregnant women who were diagnosed by B-ultrasound breech pregnancy at 34-36 weeks in regular antenatal examination from January 2014 to June 2016 were randomly divided into an observation group (n =70)and a control group (n =50).The observation group was treated with intravenous drip of terbutaline sulfate after epidural anesthesia,and then received external cephalic version under B-ultrasound monitoring.The control group received traditional knee-chest position for correcting breech presentation.The success rate of breech correction,breech version rate,cesarean section rate,vaginal delivery rate,adverse reactions,postpartum hemorrhage volume,neonatal asphyxia,and neonatal birth injury were noted and compared between the two groups.Results As compared with the control group,the observation group had a higher success rate of breech correction and a higher rate of vaginal delivery while a lower rate of cesarean section,with a significant difference (x2 =20.210,8.564;P ＜0.05).The rate of postpartum hemorrhage,neonatal asphyxia,or neonatal birth injury did not differ significantly between the two groups (P ＞ 0.05).Conclusions Application of ultrasound combined with intravenous terbutaline sulfate in external cephalic version is easy to operate and has a higher success rate and greater safety,significantly reducing the rate of cesarean section and improve the success rate of vaginal delivery.
