Pilonidal sinus surgery (PSS) can be done with local anaesthetic infiltration, spinal anaesthesia, or general anaesthesia (GA). Erector spinae plane block (ESPB) is used for peri-operative analgesia. Erector spinae muscles extend to the sacral region, so it can provide post-operative analgesia in PSS. We evaluate the post-operative analgesic efficacy of ultrasound-guided sacral ESPB, a novel technique, in patients undergoing PSS under GA.
