目的分析胎儿不同出生体重对产程进展及分娩结局的影响。方法足月单胎头位产妇840例,孕周37-41周。按新生儿出生体重分为A组(2500-2999g,97例)、B组(3000-3499g,384例)和C组(≥3500g,359例)。分析三组产程异常和分娩结局。结果C组产妇活跃期停滞、继发性宫缩乏力和持续性枕横位或枕后位的发生率均高于A、B组(P<0.05)。与A组和B组比较,C组的剖宫产率高(35.7%vs.26.8%和22.9%)(P<0.05)。随着出生体重的增加,羊水污染和新生儿转新生儿重症监护室率有升高趋势(P<0.05)。A组无产后出血病例,B组产后出血率1.8%,而C组产后出血率为4.7%高于A组和B组(P<0.05)。结论产前检查及时了解胎儿的体重增长,指导孕妇合理营养摄入和适当活动,避免新生儿超重,有助于缩短产程,提高阴道分娩成功率,降低剖宫产率和产后出血率。
Objective To analyze the effect of different birth weight of fetus on labor progress and delivery outcome. Methods 840 full-term single-head mothers, gestational weeks 37-41 weeks. According to the newborn’s birth weight, the patients were divided into group A (2500-2999g, 97 cases), group B (3000-3499g, 384 cases) and group C (3500g, 359 cases). Three sets of labor abnormalities and delivery outcomes were analyzed. Results The active stagnation, secondary uterine atony and persistent occiput posterior or posterior occipitocele in group C were higher than those in groups A and B (P <0.05). Cesarean section rates in group C were higher (35.7% vs.26.8% and 22.9%, respectively) than those in group A and B (P <0.05). With the increase of birth weight, amniotic fluid contamination and newborn neonatal intensive care unit rate has increased (P <0.05). In group A, there was no case of postpartum hemorrhage. The rate of postpartum hemorrhage in group B was 1.8%, while the rate of postpartum hemorrhage in group C was 4.7% higher than that in group A and group B (P <0.05). Conclusions Prenatal examination can keep abreast of the weight gain of fetus, guide the reasonable nutritional intake and appropriate activities of pregnant women, avoid the overweight of newborns, shorten the labor process, improve the success rate of vaginal delivery and reduce the rate of cesarean section and postpartum hemorrhage.
