Abstract To analyze the influencing factors of different induced labour schemes of women during the second trimester of pregnancy. Methods: The clinical data of 210 women with induced labour during 13-27gestational weeks from January 2020 to September 2022 were analyzed retrospectively, including 155 with single induced labour scheme in group A and 55 cases with combined induced labour scheme in group B. The influence of the clinical characteristics of the women on their selection of different induced labour scheme was analyzed by logistic regression method. Results: The results of single factor analysis showed that the number of gravidity (1.9±0.6 times), the parity (1.8±0.5 times), and the gestational weeks (22.2±0.4 weeks) of the women in group B were significantly higher than those (0.6±0.2 times, 23.8±3.6 times, and 21.3±3.7 weeks) of the women in group A. The rates of history of cesarean section (32.4%), the placental abnormality (12.7%), and the pregnancy-induced hypertension (25.4%) of the women in group B were significantly higher than those (14.2%, 3.9%, and 12.9%) of the women in group A (P＜0.05). There were no significant differences in the incidences of different induced labour events of the women between the two groups (P>0.05). Multivariate regression analysis showed that the history of cesarean section, the gestational weeks, and the number of pregnancies of the women were the factors affecting their selection of combined induced labour scheme (P＜0.05). Conclusion: For the pregnant women with cesarean section history, with higher gestational weeks, or with greater number of pregnancies, the combined induced labour scheme should be considered for them so as to improve the effect and safety of the induced labour.
