Objective To study the different selections of delivery mode of pregnant women, and compare their outcomes. Methods Data of 7 509 pregnant women hospitalized in the General Hospital of Tianjin Medical University between January 2013 and December 2014 were retrospectively analyzed. Of them, there were 6 229 cases of primipara and 1 280 cases of multipara. The numbers of vaginal delivery and cesarean delivery were statistical analyzed between primipara and multipara. The cesarean delivery indications of multipara was also studied. The vaginal delivery rates and cesarean delivery rates, and their outcomes were compared between primipara and scar uterus maternal pregnancy. Results The cesarean delivery rate was higher in multipara than that of primipara (69.06%vs. 57.54%,χ2=59.19, P<0.05). Among them, 631 cases were uterine scar pregnancy, 39 cases (6.18%) were vaginal delivery and 592 cases (93.82%) were cesarean delivery. The uterine scar was the main indicator for cesarean delivery in multipara. Compared the outcomes of cesarean delivery, the weight of neonatal body mass was relatively light, the hospital stay was shorter, the amount of 24 h postpartum bleeding and postpartum fever were less in vaginal delivery in primipara and pregnant women with uterine scar ( P<0.05). There were no significant differences in scores of newborn. There were no significant differences in outcomes of vaginal delivery between primipara and pregnant women with uterine scar. Compared outcomes of cesarean delivery between multipara with scar uterus and primipara, there were increased maternal blood loss and postpartum fever in multipara with scar uterus (P<0.05). Conclusion The cesarean delivery is still the mainly mode for multipara. The vaginal delivery is the best mode for pregnant women with scar uterus compared with that of primipara. The vaginal delivery is the safer way of delivery for pregnant women.
