Intrauterine life demands unique respiratory and nutrient mechanisms, and it seems reasonable that some cardiorespiratory responses developed for later extrauterine life would not necessarily be entirely appropriate for the fetal period. In other words, a human fetus may not always be acting in its own best interest when it responds to intrauterine stress with what are appropriate extrauterine responses, such as gasping or the baroreflex (bradycardia). The detrimental effects of in utero gasping of meconium are well known, but the potentially harmful effects of inappropriate fetal bradycardia are little appreciated. A review of this condition is presented.
子宫内的生命需要独特的呼吸和营养机制，似乎有理由认为，一些为宫外生活后期发展而来的心肺反应不一定完全适用于胎儿期。换句话说，当人类胎儿以宫外适当的反应（如喘息或压力反射（心动过缓））来应对子宫内压力时，它可能并不总是在以自身最佳利益行事。子宫内喘息吸入胎粪的有害影响是众所周知的，但不适当的胎儿心动过缓的潜在有害影响却鲜为人知。本文对此情况进行了综述。
