A 21 year old healthy parturient was diagnosed as having a fetus with micrognathia. She was scheduled for an ex-utero intrapartum treatment (EXIT) procedure. General anesthesia consisted of remifentanil, nitrous oxide, and midazolam. Intravenous nitroglycerin was used for uterine relaxation. This technique offered hemodynamic stability and provided uterine relaxation that may be rapidly terminated. For the fetus, it provided excellent transplacental anesthesia. Supplemental direct fetal anesthesia is recommended to prevent the rapid decline of analgesia/anesthesia that occurs after placental separation.
一位 21 岁健康的产妇被诊断为胎儿患有小下颌畸形。她被安排进行子宫外产时治疗（EXIT）手术。全身麻醉包括瑞芬太尼、一氧化二氮和咪达唑仑。静脉注射硝酸甘油用于子宫松弛。这种技术提供了血流动力学的稳定性，并提供了可能迅速终止的子宫松弛。对于胎儿，它提供了极好的胎盘麻醉。建议补充直接胎儿麻醉，以防止胎盘分离后镇痛/麻醉迅速下降。
