The elimination of nitrous oxide by ten infants whose mothers had received 50% nitrous oxide in oxygen and enflurane 0.6-1% during general anaesthesia for Caesarean section was studied. The concentration of nitrous oxide detected in end-expired gas ranged from 1 to 4 vol% (mean 1.9 vol%). These levels are too low to produce significant diffusion hypoxia in vigorous neonates. However, a minority of infants may be adversely affected and it is recommended that oxygen-enriched air be administered to infants whose mothers have received nitrous oxide.
对10名婴儿一氧化二氮的消除情况进行了研究，这些婴儿的母亲在剖宫产全身麻醉期间接受了50%的一氧化二氮和0.6 - 1%的安氟醚。呼气末气体中检测到的一氧化二氮浓度范围为1至4体积%（平均1.9体积%）。这些水平太低，不会在活力充沛的新生儿中产生明显的弥散性缺氧。然而，少数婴儿可能会受到不利影响，建议对母亲接受过一氧化二氮的婴儿给予富氧空气。
