Effect of Stimulating the BL67 Point on Fetal Correction from Breech to Cephalic Presentation and Natural Delivery after the 36 Weeks of Pregnancy: A Randomized Clinical Trial

摘要

Objective::Various techniques are proposed for changing fetal presentation. We aimed to assess the effect of BL67 point stimulation on correcting breech presentation and natural delivery in women at 36-38 gestational weeks.Methods::A parallel single blinded randomized clinical trial was conducted on 72 eligible pregnant women with breech presentation at the 36 weeks of pregnancy. The subjects were divided into two groups - intervention ( n = 36) and control groups ( n = 36) by block randomization method. The intervention group stimulated the BL67 point by self-administration for 20 min once a day for 2 weeks. Finally, the appearance of cephalic presentation and rate of vaginal delivery was compared between the groups ( n1 = n2 = 32) using the Chi-square test and multivariate logistic regression. Results::The correction of breech to cephalic presentation occurred in 53.1% of patients in the intervention group. The adjusted relative risk ( RR) for fetal correction from breech to cephalic was 1.80 ( RR = 1.80, 95% confidence interval [ CI], 1.13-5.17). It was shown that the stimulation of the BL67 point increased the correction of breech to cephalic presentation. In addition, the rate of vaginal delivery increased by >4-fold ( RR = 4.16, 95% CI, 2.54-6.82) by correction to cephalic presentation. Moreover, 65.6% of mothers in intervention group and 90.6% in the control group underwent cesarean section. Conclusions::The stimulation of the BL67 point is a safe, inexpensive, and effective method that can be self-administered at home for fetal correction from breech to cephalic presentation in women with breech presentations during 36-38 gestational weeks. This promotes uncomplicated natural childbirth.
