Parasacral ischial plane block for lower limb wound debridement surgeries – A case series

Parasacral ischial plane block is a novel fascial plane approach to sacral plexus. Parasacral ischial plane block is technically less challenging and obviates the need for direct visualisation of sacral plexus. It can reliably be performed in limb-amputated patients where neuromuscular stimulation is less useful. Ten patients of the American Society of Anesthesiologists physical status II-IV, aged between 18 and 70 years, posted for elective lower limb debridement surgeries were enroled in this prospective case series. The time taken to perform the block was ≤4 minutes in all cases. Time taken for full sensory loss was 9 minutes to 15 minutes. None of the patients developed a complete motor blockade till 30 minutes after our observation. None of the patients required intraoperative supplemental analgesia. This block is technically easy, less time-consuming, and provided adequate sensory analgesia in below-knee surgeries.
