目的:探讨巨大儿的发生因素、产前诊断及分娩方式。方法:回顾性分析自2004年1月～2006年12月在该院分娩的280例巨大儿发生的相关因素、诊断、分娩方式及分娩结局。结果:280例巨大儿孕妇有112例(40.00%)身高≥162cm,103例(36.79%)超重,138例(49.29%)经产妇,孕周>40周占53.93%;宫高+腹围≥138 cm者与对照组比较有统计学差异(χ2=114.07,P<0.01),双顶径和股骨长与对照组比较有统计学差异(P<0.01),产程异常率和剖宫产率与对照组比较差异有统计学意义(P<0.01)。结论:巨大儿的发生与孕妇身高、体重、产次、孕周及遗传因素有关;巨大儿的诊断要通过宫高+腹围、双顶径、股骨长等多项指标综合判断;巨大儿不宜作为剖宫产的常规指征,但出现异常应放宽剖宫产指征。
Objective: To explore the causes of macrosomia, prenatal diagnosis and mode of delivery. Methods: Retrospective analysis of the related factors, diagnosis, mode of delivery and delivery outcomes of 280 cases of giant infants delivered in our hospital from January 2004 to December 2006 were retrospectively analyzed. Results: Among the 280 cases of giant maternal age, 112 (40.00%) were over 162cm in height, 103 (36.79%) were overweight, 138 (49.29%) were maternal and accounted for 53.93% 138 cm and the control group were statistically significant (χ2 = 114.07, P <0.01), biparietal diameter and femur length compared with the control group was statistically significant (P <0.01), the rate of labor abnormalities and cesarean section rate and The difference between the control group was statistically significant (P <0.01). Conclusion: The occurrence of giant children is related to the height, weight, delivery time, gestational age and genetic factors of pregnant women. The diagnosis of giant children should be judged by multiple indicators such as uterine height + abdominal circumference, biparietal diameter and femur length. As a general indication of cesarean section, but abnormalities should be relaxed cesarean indications.
