Abstract

The effect of fetal breathing movements (FBM) of maternal breathing of 50% oxygen was examined. The procedure caused a two-fold rise in maternal arterial Po2 and did not alter FBM in normal pregnancy. In pregnancy complicated by intrauterine growth retardation (IUGR) a substantial increase in the incidence of FBM was recorded during hyperoxia (control 29.8 +/- 3.9%, hyperoxia 68.2 +/- 3.6). No such change was observed in pregnancies where IUGR was suspected but not proven at delivery.

摘要

研究了母体呼吸50%氧气对胎儿呼吸运动（FBM）的影响。该操作使母体动脉血氧分压升高了两倍，且未改变正常妊娠中的胎儿呼吸运动。在并发宫内生长受限（IUGR）的妊娠中，高氧期间胎儿呼吸运动的发生率显著增加（对照组29.8±3.9%，高氧组68.2±3.6%）。在怀疑有宫内生长受限但分娩时未得到证实的妊娠中未观察到这种变化。
