Spinal anaesthesia is the gold standard for elective caesarean section. This technique presents several adverse effects. We report a severe case of hypothermia (33.3 degrees C) after spinal administration of bupivacaine (10 mg) and morphine (100 microg) for elective caesarean section. After excluding other causes of hypothermia, this one could be explained by both the own effects of local anaesthesia (i.e. peripheral vasodilatation) and by the central effect of intrathecal morphine. Because hypothermia is not predictable after spinal injection of morphine both monitoring of central temperature and active warming of the patients could be proposed. Naloxone has been proposed in a case of hypothermia related to spinal injection of morphine.
脊髓麻醉是择期剖宫产的金标准。该技术存在多种不良反应。我们报告了一例择期剖宫产患者在脊髓注射布比卡因（10毫克）和吗啡（100微克）后发生严重体温过低（33.3摄氏度）的病例。在排除其他体温过低的原因后，这一情况可由局部麻醉本身的作用（即外周血管扩张）以及鞘内注射吗啡的中枢作用来解释。由于脊髓注射吗啡后体温过低无法预测，因此建议对患者进行中心体温监测并积极保暖。对于与脊髓注射吗啡相关的体温过低病例，有人提出使用纳洛酮。
