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 (n 1 = n 2 = 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.
