BACKGROUND
This study aims to detect the effects of increased BMI on labor outcomes in primigravida pregnant women.
METHODS
A cross-sectional study involved 600 full-term singleton primigravida pregnant women who presented in the active phase of labor to the labor ward. They were divided according to BMI into three equals groups; women with normal BMI (group I), overweight women (group II), and women with class I obesity (group III).
RESULTS
We found that high BMI was associated with a significantly increased risk of Caesarean section (C.S.) (13% in group I, 18% in group II and 40% in group III). Women with higher BMI and delivered vaginally had a significantly prolonged first and second stage of labor, consequently increased the need for oxytocin augmentation as well as the oxytocin dose. Regarding the maternal and fetal outcomes, there are significantly increased risks of postpartum sepsis, perineal tears, wound infection, as well as significantly increased birth weight and longer neonatal stay in the neonatal unit (NNU).
CONCLUSION
Obese primigravida pregnant women were at higher risk of suboptimal outcomes. Besides, prolonged first and second stages of labor and the incidence of C.S. have also been increased.
背景
本研究旨在探讨 BMI 增加对初产妇分娩结局的影响。
方法
采用横断面研究方法，选取 600 例足月、单胎、初产妇，这些产妇均在活跃期进入产房，根据 BMI 将其分为三组：正常 BMI（I 组）、超重（II 组）和 I 度肥胖（III 组）。
结果
我们发现高 BMI 与剖宫产（C.S.）的风险显著增加相关（I 组为 13%，II 组为 18%，III 组为 40%）。BMI 较高且经阴道分娩的产妇第一产程和第二产程明显延长，因此需要催产素加强宫缩以及增加催产素剂量。关于母婴结局，产后败血症、会阴撕裂、伤口感染的风险显著增加，新生儿出生体重增加，新生儿在新生儿重症监护病房（NNU）的停留时间延长。
结论
肥胖初产妇的不良结局风险较高。此外，第一产程和第二产程延长以及 C.S.的发生率也有所增加。
