Local anaesthetic for lower-limb revascularization in high-risk patients.
BACKGROUND: A few patients with critical limb ischaemia are believed to be too unfit for an attempt at revascularization using conventional anaesthesia. METHODS: 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. RESULTS: 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. CONCLUSION: Selective use of local anaesthetic techniques extends the benefits of limb salvage to patients considered unfit for conventional anaesthesia.[1]References
