Hypoglycaemia can cause serious problems in anaesthetized patients, due to blockade by anaesthesia of the usual compensatory mechanisms. Gravid women develop hypoglycaemia more readily than non-pregnant patients because they live in a state of "accelerated starvation." Three cases are described of healthy parturients undergoing elective Caesarean section under lumbar epidural analgesia whose post-blockade hypotension was difficult to reverse until their low blood glucose concentrations had been normalized. Further investigations of the role played by blood glucose concentrations in the maintenance of cardiovascular homeostasis in pregnant women are indicated. In the meantime, a preanaesthetic blood glucose determination will facilitate measures to ensure a normal blood glucose level before induction of anaesthesia for Caesarean section.
由于麻醉会阻断通常的代偿机制，低血糖会在麻醉患者中引发严重问题。与未怀孕的患者相比，孕妇更容易发生低血糖，因为她们处于“加速饥饿”状态。本文描述了3例健康产妇在腰段硬膜外镇痛下行择期剖宫产手术的情况，这些产妇在阻滞麻醉后出现低血压，在血糖浓度恢复正常之前，低血压很难纠正。这表明需要进一步研究血糖浓度在维持孕妇心血管稳态中所起的作用。同时，麻醉前测定血糖将有助于采取措施，确保剖宫产麻醉诱导前血糖水平正常。
