The purpose of this study was to identify risk factors and to characterize infants with transient tachypnea of the newborn (TTN). A total of 67 newborns with TTN, born at gestational age (GA)>or=35 weeks, were studied. Newborns delivered before and after each study case served as controls. Mean GA was lower and cesarean section (CS) rate was higher in the TTN group (38.2+/-2.3 versus 39.5+/-1.4 weeks, p<0.001; 50.7% versus 22.4%, p<0.001). GA<38 weeks was found to be associated with increased risk for TTN in infants delivered by elective CS. TTN was associated with significant morbidities and longer hospital stay (7.2+/-5.6 versus 2.9+/-1.4 days; p<0.001). Delivery by CS and younger GA are risk factors for TTN. Although TTN is a self-limited disease, it is associated with significant morbidities. Scheduling elective CS at GA of not less than 38 weeks may decrease the frequency of TTN.
本研究的目的是确定危险因素并对新生儿暂时性呼吸急促（TTN）婴儿的特征进行描述。共研究了67例孕周（GA）≥35周的TTN新生儿。每个研究病例前后分娩的新生儿作为对照。TTN组的平均孕周较低，剖宫产（CS）率较高（38.2±2.3周对39.5±1.4周，p<0.001；50.7%对22.4%，p<0.001）。发现在择期剖宫产分娩的婴儿中，GA<38周与TTN风险增加相关。TTN与显著的发病率和更长的住院时间相关（7.2±5.6天对2.9±1.4天；p<0.001）。剖宫产分娩和较小的孕周是TTN的危险因素。虽然TTN是一种自限性疾病，但它与显著的发病率相关。将择期剖宫产安排在孕周不少于38周时可能会降低TTN的发生率。
