On two separate occasions, a 78-year-old obese man suffering from congestive cardiac failure and peripheral vascular disease, required epidural anaesthesia for surgery to his leg. The dosage requirement on the first occasion was large and much greater than on the second occasion. Reasons for the difference in dosage are discussed. We suggest an epidural catheter should be inserted 3 cm into the epidural space.
在两个不同的场合，一名患有充血性心力衰竭和外周血管疾病的78岁肥胖男子，因腿部手术需要硬膜外麻醉。第一次的剂量需求很大，远大于第二次。文中讨论了剂量差异的原因。我们建议将硬膜外导管插入硬膜外腔3厘米。
