The effect of maternal inhalation of 50 per cent oxygen upon fetal breathing movements was investigated. No significant effect was noted in patients with normal pregnancies or in those complicated by insulin dependent diabetes or mild pre-eclampsia. A significant increase in fetal breathing movements was observed in those pregnancies complicated by either severe pre-eclampsia or fetal growth retardation.
研究了母体吸入50%氧气对胎儿呼吸运动的影响。在正常妊娠患者、合并胰岛素依赖型糖尿病或轻度先兆子痫的患者中未观察到显著影响。在合并严重先兆子痫或胎儿生长受限的妊娠中，观察到胎儿呼吸运动显著增加。
