To test whether epidural anaesthesia for foot and ankle surgery is associated with an unacceptably high incidence of inadequate surgical analgesia, we prospectively compared two groups of patients, one undergoing foot or ankle surgery (160 patients) and the other surgical procedures not performed in areas innervated by L5-S1 ( (168 patients). Lumbar epidural anaesthesia was performed in both groups by administering carbonated lignocaine 2% with adrenaline 1:200000. Seven patients in the foot-ankle group (4.4%) and 10 in the group for comparison (5.9%) exhibited inadequate surgical analgesia. This difference is not statistically significant. Within the foot-ankle group, a significantly lower dose of local anaesthetic per spinal segment had been given to patients who displayed inadequate analgesia, compared with those who exhibited satisfactory analgesia (P < 0.05).
为了检验足踝手术的硬膜外麻醉是否与手术镇痛不足的发生率高到不可接受相关，我们前瞻性地比较了两组患者，一组接受足踝手术（160例患者），另一组接受不在L5-S1神经支配区域进行的手术（168例患者）。两组均通过给予2%碳酸利多卡因加1:200000肾上腺素进行腰段硬膜外麻醉。足踝组有7例患者（4.4%）手术镇痛不足，对照组有10例患者（5.9%）手术镇痛不足。这种差异无统计学意义。在足踝组中，与镇痛效果满意的患者相比，镇痛不足的患者每脊髓节段给予的局部麻醉剂剂量显著更低（P<0.05）。
