如胎儿呼吸运动所示,孕妇摄取少量酒精,能抑制胎儿的中枢神经系统。宫内的呼吸运动是间歇的,在羔羊仅发生在胎儿活动时,并产生非同步的脑电图。给母羊服巴比妥盐或安定能降低胎儿的呼吸率,胎儿的呼吸不依赖于化学感受器的刺激,能视为胎儿中枢神经系统睡醒的指标,在人类孕妇可容易地采用非损伤性技术进行测定。我们对六个孕妇孕期在34～38周分二种情况用准时超声扫描仪监护胎儿呼吸,一种情况给孕妇服300毫升桔子汁内含15毫升酒精,(等于40毫升伏特加),而另一种孕妇仅服桔子汁,随机双肓分配,在服用前30分钟胎儿保持持续的呼吸运动,平均次数为46±25%,在服酒精后的30～60分钟其比率下降为14±
As fetal movement shows, pregnant women intake of a small amount of alcohol, can inhibit the fetus’s central nervous system. Intrauterine respiratory movement is intermittent, in the lamb occurs only when fetal activity, and produce asynchronous EEG. To ewes taking barbiturate salt or diazepam can reduce the respiration rate of the fetus, the fetus’s breathing does not depend on chemoreceptor stimulation, can be regarded as an indicator of fetal central nervous system waking up in pregnant women can be easily used non-invasive Technical determination. We monitored fetal respiration with six on-time ultrasound scanners in 34 to 38 weeks during pregnancy, and in one case, 300 ml of orange juice for pregnant women contained 15 ml of alcohol (equivalent to 40 ml of vodka) while the other Pregnant women only served orange juice and were randomly allocated. The fetus maintained continuous respiratory activity for 30 minutes before taking the average number of 46 ± 25%. After 30 to 60 minutes of taking alcohol, its rate dropped to 14 ±
