Role of sphenopalatine ganglion block for postoperative analgesia after functional endoscopic sinus surgery

The aim of this study was to evaluate the analgesic efficacy of sphenopalatine ganglion block performed under general anesthesia in patients undergoing functional endoscopic sinus surgery (FESS) with operative blood loss and postoperative complications (headache, visual disturbances, nausea, vomitin...

Description
Summary:The aim of this study was to evaluate the analgesic efficacy of sphenopalatine ganglion block performed under general anesthesia in patients undergoing functional endoscopic sinus surgery (FESS) with operative blood loss and postoperative complications (headache, visual disturbances, nausea, vomiting, sore throat, swallow difficulty). Forty-five consenting patients were randomized to receive bilateral sphenopalatine ganglion block with saline (Group S, n  = 15), bupivacaine 0.5% (Group B, n  = 15), or levobupivacaine 0.5% (Group L, n  = 15) immediately following induction of general anesthesia. Esmolol was given during the intraoperative period for a 20% increase in arterial mean pressure or heart rate. Postoperative pain scores were checked on arrival at the postanesthesia care unit, 2, 6, and 24 h after surgery and diclofenac was administered intramuscularly for pain score ≥4. A statistically significant reduction was present in postoperative Visual Analog Scale scores between Group S and the block Groups B and L ( p
