Successful postoperative analgesia with ilio-inguinal nerve block following sclerotherapy for a labial venous malformation.


Though ilio-inguinal nerve block has been commonly utilised in male urologic surgery, a single injection ilio-inguinal nerve block alone has not previously been reported for analgesia of the vulva. In this report, we describe the case of a 14-year-old girl undergoing sclerotherapy of a venous malformation affecting the labia majora and minora. After induction of anaesthesia, we performed an ultrasound-guided ilio-inguinal nerve block using a total volume of 15 ml of ropivacaine 0.2% with 1 μg.ml dexmedetomidine which provided effective postoperative analgesia. Though the patient received intravenous analgesia intra-operatively and had an inpatient bed reserved in anticipation of severe postoperative pain, she required no further analgesia and was discharged home following 2 hours in the postoperative anaesthesia care unit. With the additional use of dexmedetomidine resulting in prolonged efficacy of the block, the patient reported effective postoperative relief for approximately 30 hours, solely using ibuprofen for pain relief. This case reminds clinicians that the ilio-inguinal nerve block may provide benefit not only for male urologic surgery but also for procedures involving the external female genitalia, with extended analgesia with the use of dexmedetomidine.
