[Comparison among measures to prevent intrauterine adhesions after artificial abortion].

OBJECTIVE: To investigate the clinical efficacy of oral medicine and sodium hyaluronate in prevention of intrauterine adhesions after artificial abortion.


METHODS: A total of 572 patients with early pregnancy termination through artificial abortion, who experienced two or more times of abortion, were retrospectively analyzed. Patients were randomly and voluntarily divided into 4 groups: an artificial cycle group, a drospirenone and ethinylestradiol tablets group, a sodium hyaluronate group, and a control group. The thickness of the endometrium, return time of menses, and the status of intrauterine adhesions were observed.


RESULTS: The thickness of the endometrium in the artificial period group was greater than that in the control group (P<0.001). It was less in the drospirenone and ethinylestradiol tablets group comparing with that in the control group (P<0.001). There was no significant difference in the thickness of the endometrium between the sodium hyaluronate group and the control group (P=0.717). Return time of menses in the artificial menstrual cycle group and the drospirenone and ethinylestradiol tablets group was shorter than that in the control group (P<0.001). There was no significant difference in return time of menses between the sodium hyaluronate group and the control group (P=0.813). The incidence of intrauterine adhesions could be reduced by the 3 preventive measures (All P<0.01).


CONCLUSION: Drugs for artificial cycle and drospirenone and ethinylestradiol tablets medication immediately after artificial abortion can effectively promote endometrial repair and reduce the incidence of intrauterine adhesions. However, for the patients with poor compliance, drospirenoneand ethinylestradiol tablets are the first choice for prevention of intrauterine adhesion.
