Abstract Objective: To investigate the influence of postoperative transcutaneous electrical stimulation therapy on the endometrial thickness and endometrial blood flow of women with missed abortion or incomplete abortion. Methods: 144 women who underwent curettage due to missed abortion or incomplete abortion were enrolled and were randomly divided into the observation group and the control group (72 cases in each group) from January 2016 to January 2018. The women in the control group were given conventional treatment and the women in the observation group were treated by transcutaneous electrical stimulation therapy combined with conventional treatment. The situations of postoperative vaginal bleeding, menstrual recovery, and rate of complications of women were compared between the two groups. The endometrial thickness and pulsation index (PI), resistance index (RI), ratio of peak systolic velocity to end diastolic velocity (S/D) of uterine spiral artery of all included women were measured. Results: After treatment, the volume of vaginal bleeding, the time of vaginal bleeding, and menstrual recovery time of women in the observation group were significant lower than those of women in the control group (P<0.05), the endometrial thickness of women in the observation group was significant higher than that of women in the control group, while the values of RI, PI and S/D of women in the observation group was significantly lower than those of women in the control group (P<0.05). The incidences of less menstrual volume and abdominal pain of women in the observation group were 2.8% and 2.8%, respectively, which were significant lower than those (16.7% and 12.5%) of women in the control group (P<0.05). There were no significant difference in the rates of pelvic infection and intrauterine adhesion (IUA) between the two groups (P>0.05). Conclusion: The lower abdominal transcutaneous electrical stimulation used for treating women with missed abortion or incomplete abortion after curettage can increase of endometrial thickness and improve the hemodynamic state of the endometrium, can reduce postoperative vaginal bleeding, promote menstrual rehydration, and prevent less menstrual amount and other complications.
