目的探讨近足月胎儿生长受限(FGR)的适宜分娩孕周。方法收集2010年1月至2015年9月分娩孕周≥36周、单胎、头位分娩的FGR病例符合入选标准与排除标准的孕妇146例,按其分娩孕周分为研究组(38周后分娩)和对照组(36~37+6周分娩),并对两组资料进行比较分析。结果研究组的孕妇较对照组延迟15 d分娩,剖宫产率降低(χ~2=5.132,P=0.023);而且研究组的新生儿出生体重较对照组明显增加(t=6.958,P<0.001),入住NICU的概率明显下降(χ~2=10.537,P=0.001),住院天数缩短(t=-2.291,P=0.023)。结论FGR的孕妇在孕38周后分娩与在孕36周~37+6周分娩相比,不增加其妊娠不良结局和围产儿不良结局。
Objective To investigate the appropriate gestational gestational age of nearly full-term fetal growth restriction (FGR). Methods One hundred and sixty-six pregnant women with single and first childbirth who fulfilled the inclusion criteria and exclusion criteria from January 2010 to September 2015 were divided into study group (38 weeks) Postpartum delivery) and control group (36 ~ 37 + 6 weeks delivery), and compared the two groups of data. Results The pregnant women in the study group were delayed in delivery by 15 days and the cesarean section rate was decreased (χ ~ 2 = 5.132, P = 0.023). The newborn birth weight in the study group was significantly higher than that in the control group (t = 6.958, P < 0.001). The probability of admission to the NICU decreased significantly (χ ~ 2 = 10.537, P = 0.001) and hospitalization days decreased (t = -2.291, P = 0.023). Conclusion The pregnant women of FGR did not increase the adverse pregnancy outcomes and the unfavorable outcomes of perinatal delivery after 38 weeks ’gestation, as compared with 36 weeks’ gestation and 37 + 6 weeks gestation.
