381例足月初产妇急产围产结局及其危险因素

OBJECTIVE: : To investigate the perinatal outcome and risk factors of precipitate labor in term primipara. METHODS: : A total of 6951 full-term singleton primiparas with cephalic vaginal delivery in Women’s Hospital, Zhejiang University School of Medicine from January 2020 to December 2020 were enrolled, among whom 381 cases of precipitate labor were classified as the precipitate labor group and 762 cases of normal labor were randomly selected as the control group. The perinatal outcomes of the two groups were compared, and the risk factors of precipitate labor were analyzed by multivariate logistic regression. RESULTS: : The incidence of precipitate labor in full-term, singleton pregnancy and cephalic primiparas was 5.48% (381/6951). The durations of the first and second stages of labor in the precipitate labor group were significantly shorter than that in the control group ( P0.05). Compared with the control group, the incidence of soft birth canal laceration in the precipitate labor group was increased ( P0.05). Multivariate logistic regression analysis showed that maternal height ( OR=1.038, 95% CI: 1.010–1.067, P
