A few patients with critical limb ischaemia are believed to be too unfit for an attempt at revascularization using conventional anaesthesia.
A retrospective analysis was undertaken of 46 revascularization procedures performed in high-risk patients for critical limb ischaemia between 1989 and 1995, in which local anaesthetic techniques were utilized in preference to general or spinal anaesthesia.
Cumulative survival rates at 6, 12 and 24 months were 67, 57 and 51 per cent. Primary patency rates were 77 per cent at 6 months, 67 per cent at 12 months and 53 per cent at 24 months, with associated limb salvage rates of 87, 87 and 79 per cent.
Selective use of local anaesthetic techniques extends the benefits of limb salvage to patients considered unfit for conventional anaesthesia.
一些严重肢体缺血患者被认为身体过于虚弱，无法尝试使用传统麻醉进行血管重建。
对1989年至1995年间在高危严重肢体缺血患者中进行的46例血管重建手术进行回顾性分析，其中优先采用局部麻醉技术而非全身麻醉或脊髓麻醉。
6个月、12个月和24个月的累积生存率分别为67%、57%和51%。6个月时的初始通畅率为77%，12个月时为67%，24个月时为53%，相应的肢体挽救率为87%、87%和79%。
选择性使用局部麻醉技术将肢体挽救的益处扩展到被认为不适合传统麻醉的患者。
