A review is given covering four different series of studies revealing maternal hypoxaemia during labour, in spite of normal maternal heart and lung function. The previous Swedish use of 100% nitrous oxide inhalation during contractions lead to serious maternal hypoxaemia. The use of pethidine in combination with hyperventilation during the contractions leads to long respiratory pauses and maternal hypoxaemia in between the contractions. Excessive hyperventilation during the contractions may in itself lead to a so called hyperventilation-hypoventilation syndrome with maternal hypoxaemia. Finally excessive sustained pushing with maximal effort and no ventilation also leads to maternal hypoxaemia. Thus maternal hypoxaemia, although largely unknown is not too infrequent and is mainly of iatrogenic origin. Proper knowledge should suffice for prevention.
本文综述了四项不同系列的研究，这些研究揭示了尽管产妇心肺功能正常，但在分娩过程中仍会出现母体低氧血症。瑞典以前在宫缩期间使用100%氧化亚氮吸入会导致严重的母体低氧血症。在宫缩期间使用哌替啶并伴有过度通气会导致长时间的呼吸暂停以及宫缩间期的母体低氧血症。宫缩期间过度通气本身可能会导致一种所谓的过度通气-通气不足综合征，并伴有母体低氧血症。最后，持续过度用力且不进行通气的推挤也会导致母体低氧血症。因此，母体低氧血症虽然在很大程度上不为人所知，但并不罕见，且主要是医源性的。适当了解相关知识应足以预防。
