经皮穴位电刺激对剖宫产产后抑郁的预防作用

Efficacy of transcutaneous electrical acupoint stimulation in prevention of postpartum depression after Cesarean section

目的观察经皮穴位电刺激对剖宫产产后抑郁的预防作用。方法 80例择期行剖宫产的产妇随机均分为两组。对照组采用单纯蛛网膜下腔阻滞,试验组在对照组基础上加用经皮穴位电刺激。术毕两组均行静脉患者自控镇痛。比较两组产妇术中切皮时(T1)、婴儿取出时(T2)、缝合子宫时(T3)和关腹前腹腔探查时(T4)的疼痛程度数字评价量表(NRS)评分和术后24 h不良反应发生率。比较两组术前1 d和术后第1、3和7天的汉密尔顿抑郁量表(HAMD)评分及爱丁堡产后抑郁量表(EPDS)评分。结果试验组T1~T4时的NRS评分低于对照组(P<0.05),术后第1、3和7天的HAMD及EPDS评分低于对照组(P<0.05)。两组术后24 h不良反应发生率无统计学差异(P>0.05)。结论经皮穴位电刺激对剖宫产产后抑郁具有一定的预防作用。

Objective To observe the efficacy of transcutaneous electrical acupoint stimulation(TEAS) in the prevention of postpartum depression after Cesarean section.Methods Eighty parturient women undergoing elective Cesarean section were equally and randomly divided into two groups.Group C was treated with subarachnoid block alone and group A was given additional TEAS.Intravenous patient-controlled analgesia was performed after operation in both groups.The numerical rating scale(NRS) score of pain at skin cutting(T1),baby removal(T2),uterus suture(T3) and abdominal exploration(T4) and the incidence of adverse response within 24 hours after operation were compared between the two groups.The scores of Hamilton depression scale(HAMD) and Edinburgh postnatal depression scale(EPDS) one day before operation and on the 1st,3rd and 7th day after operation were compared between the two groups as well.Results The NRS scores at T1-T4 were lower in group A than those in group C(P<0.05).The scores of HAMD and EPDS on the 1st,3rd and 7th day after operation were lower in group A than those in group C(P<0.05).There was no significant difference in the incidence of adverse response within 24 hours after operation between the two groups(P>0.05).Conclusion TEAS has a certain preventive effect on postpartum depression in the parturient women after Cesarean section.
