In a prospective, unselected study of all 4,659 infants born in Göteborg, Sweden, risk factors for all kinds of neonatal respiratory disturbances (RD) after Caesarean section (CS) were analyzed. After CS, a significantly increased incidence rate of RD was found compared to vaginal delivery (24.6% vs. 5.5%). The increased overall risk affected full term infants only but IRDS was more common after CS in preterm infants. Rupture of membranes or uterine contractions prior to CS significantly reduced the incidence rate of RD in full term infants. Acute maternal complications did not affect the incidence. The elevated RD rate could partly be related to an increased incidence of low Apgar score after CS, and to absence of labour and rupture of membranes before the CS. But full term infants with Apgar score of 7 or more, delivered surgically after rupture of membranes and start of contractions, still had almost three times higher incidence of RD.
在一项对瑞典哥德堡出生的所有4659名婴儿进行的前瞻性、非选择性研究中，分析了剖宫产术后各类新生儿呼吸障碍（RD）的危险因素。剖宫产术后，与阴道分娩相比，RD的发病率显著增加（24.6%对5.5%）。整体风险增加仅影响足月儿，但早产儿中剖宫产术后IRDS更常见。剖宫产术前胎膜破裂或子宫收缩显著降低了足月儿RD的发病率。急性母体并发症不影响发病率。RD率升高部分可能与剖宫产术后低Apgar评分发生率增加以及剖宫产术前未临产和胎膜未破裂有关。但Apgar评分7分及以上、胎膜破裂和开始宫缩后手术分娩的足月儿，RD发病率仍几乎高出三倍。
