Objective To investigate the clinical effect of Wujia biochemical capsule combined with thermoelectric complex therapy instrument on uterine retroplasia after abortion. Methods 240 cases of uterine rehabilitation after abortion from April 2018 to August 2019 were selected and randomly divided into two groups. The control group were performed routine postoperative treatment, while the research group were performed five plus biochemical capsules combined with thermoelectric complex therapy instruments on the basis of routine postoperative treatment. Results The postoperative pain symptom scores were lower than that of control group(P<0.05). The average blood flow, duration of bleeding and post-operative menarche were all less than that of control group(P<0.05). The thickness of endometrium in the study group was higher than that of the control group(P<0.05), and the longitudinal and transverse diameters of the uterus were shorter than those of the control group(P<0.05). Conclusion Wujia biochemical capsule combined with thermoelectric complex therapy instrument has a good effect on the treatment of involution of uterus after abortion and is worth promoting.
