Case Report: Erector Spinae Block in Perforated Viscus.

Background: Erector spinae plane block (ESPB) a new block described for post-operative analgesia. Since 2016 the block has become a common practice in many institutions globally. Evidence has shown that ESPB is superior to truncal and abdominal wall blocks for many thoracic and abdominal surgeries.

Case presentation: A 29-year-old male, ASA (American Society of Anesthesiologists) IIE patient presented with acute appendicitis. Patient was scheduled to undergo Laparoscopic Appendicectomy under general anesthesia (GA) with ESPB for post op analgesia. In the operating room after induction of GA patient received an ultrasound (US) guided bilateral ESPB at T10 level of the spinal cord with 20 mls of 0.25% levobupivacaine on each side. Intraoperatively the appendix was found to be normal and there was an incidental finding of perforated superior/first part of duodenum (D1). The duodenum was repaired. Patient remained hemodynamically stable intraoperatively. No intraoperative morphine was required. After uneventful extubation, the patient was transferred to post-operative anesthesia care unit (PACU). Patient reported pain score of zero on a 11-point numerical rating scale (NRS) in PACU. No morphine was required in the next 24 hours on the ward either.

Conclusion: ESPB can provide opioid free analgesia for laparoscopic repair of perforated duodenal ulcer both intra and postoperatively.
