Influencing factors of intrauterine adhesions in patients with missed abortion after curettage
Objective:To analyze influencing factors of intrauterine adhesions in patients with missed abortion after curettage.Methods:A cross-sectional study was conducted on 120 patients with missed abortion admitted to the hospital from December 2020 to December 2022.The clinical data of these patients were collected.These patients were followed up for 6 months after curettage.They were divided into occurrence group and non-occurrence group according to whether intrauterine adhesion occurred.Logistic regression was used to analyze the influencing factors of intrauterine adhesions in the patients with missed abortion after curettage.Results:Among the 120 patients with missed miscarriage after curettage,35 cases experienced intrauterine adhesions,with an incidence rate of 29.17%(35/120).There were no statistically significant differences between the two groups in terms of age,body mass index,educational level,parity,comorbidities,and endometrial hyperplasia(P>0.05).The proportions of the cases with pregnancies≥3 times,previous miscarriages≥2 times,combined uterine fibroids,history of cesarean section,combined pelvic inflammatory disease,secondary curettage,history of curettage,amenorrhea after curettage,and intraoperative negative pressure suction pressure≥300 mmHg in the occurrence group were higher than that in the non-occurrence group,and the differences were statistically significant(P<0.05).Logistic regression analysis showed that pregnancies≥3 times,previous miscarriage≥2 times,combined uterine fibroids,history of cesarean section,combined pelvic inflammatory disease,secondary curettage,history of curettage,amenorrhea after curettage,and intraoperative negative pressure suction pressure≥300 mmHg were all risk factors for uterine adhesions in the patients with missed abortion after curettage(OR>1,P<0.05).Conclusions:Pregnancies≥3 times,previous miscarriage≥2 times,combined uterine fibroids,history of cesarean section,combined pelvic inflammatory disease,secondary curettage,history of curettage,amenorrhea after curettage,and intraoperative negative pressure suction pressure≥300 mmHg are the risk factors for uterine adhesions in the patients with missed abortion after curettage
