Abstract To systematically evaluate the effect of the percutaneous high-frequency electrical stimulation (PHFES) of the Neiguan point for the prevention and treatment of the hypotension of women during cesarean section. Methods: The databases, such as PubMed, Embase, Web of science, Cochrane Library, CNKI, Wanfang Data, VIP and CBM, were searched by computer. The randomized controlled trials (RCTs) on the effect of PHFES of the Neiguan point for the prevention and treatment of the hypotension of the women during cesarean section were included, and the quality of the included literatures was evaluated. The statistical analysis was performed using RevMan5.4 software. Results: 9 RCTs with 826 women were included. Compared with those of the women in the control group, the incidences of the intraoperative hypotension (RR=0.32, 95%CI 0.25-0.42), the vasoconstrictive drugs used (RR=0.34, 95%CI 0.24-0.48), the dizziness (RR=0.22, 95%CI 0.10-0.47), the chest tightness (RR=0.17, 95%CI 0.10-0.30), the dyspnea (RR=0.32, 95%CI 0.18-0.56), the nausea (RR=0.26, 95%CI 0.15-0.46) and the vomiting (RR=0.23, 95%CI 0.09-0.60) of the women in the experimental group were significantly decreased. There was no significant difference in the neonatal Apgar scores (WMD=0.08, 95%CI 0.05-0.20) of the women between the two groups. Conclusion: PHFES of the Neiguan point can significantly reduce the incidence of the rates of the hypotension, dizziness, chest tightness, dyspnea, nausea and vomiting of the women during cesarean section.
