目的探索在产程不同阶段行剖宫产术对母婴的影响。方法 2008年1月—2011年12月住院行剖宫产的孕妇2 822例为研究对象,根据是否进入产程和产程的时限分为三组,择期组2 037例、早期组670例、晚期组115例,回顾分析三组产妇在产后出血、新生儿科转住情况、产褥病率发生情况的差别,计量资料采用t检验,计数资料采用χ2检验,P<0.05为差异有统计学意义。结果早期组产后出血、新生儿科转住率(3.13%、8.80%)明显低于择期组(4.85%、17.08%)和晚期组(10.43%、23.47%)比较差异均有统计学意义(均P<0.05);早期组(4.18%)和择期组(4.12%)产褥病发生率明显低于晚期组(23.47%),比较差异均有统计学意义(均P<0.05)。结论综合评估产妇及新生儿结局,剖宫产最佳时机为产程中宫口开大2~6 cm,给每位产妇充分试产的机会,对降低剖宫产率以及母婴并发症至关重要。
Objective To explore the effect of cesarean section on maternal and infant in different stages of labor. Methods From January 2008 to December 2011, 2 822 pregnant women who were hospitalized for cesarean delivery were divided into three groups according to whether they entered the labor process or the labor process. There were 2 037 cases in the elective group, 670 cases in the early group, 115 cases were retrospectively analyzed three groups of maternal postpartum hemorrhage, neonatal transfusion cases, the incidence of puerperal morbidity differences, measurement data using t test, count data usingχ2 test, P <0.05 for the difference was statistically significant. Results In the early stage of postpartum hemorrhage, the rate of neonatal residency (3.13%, 8.80%) was significantly lower than that of the elective group (4.85%, 17.08%) and the late group (10.43%, 23.47% <0.05). The incidence of puerperal disease in early stage (4.18%) and elective stage (4.12%) was significantly lower than that in late stage (23.47%) (all P <0.05). Conclusion Comprehensive assessment of maternal and neonatal outcomes, cesarean section the best time for labor in the cervix to open large 2 ~ 6 cm, to give every mother a full trial of the opportunity to reduce cesarean section rate and maternal and child complications important.
