Abstract
Postoperative pain following nasal surgery can adversely affect recovery, increase rescue analgesic consumption, and reduce patient satisfaction. This study evaluated the postoperative analgesic effectiveness of ultrasound-guided bilateral sphenopalatine ganglion block (USG-SPGB) with bupivacaine in patients undergoing nasal surgery. An observational comparative analysis included 60 patients undergoing functional endoscopic sinus surgery, septoplasty, rhinoplasty, or combined nasal procedures. 30 patients received USG guided SPB block with 0.25% bupivacaine with dexamethasone 4 mg, 7.5 mL each side. Another 30 patients received Inj. Fentanyl 2 µg/kg i.v. intraoperatively. Pain intensity was assessed using a 0-10 visual analogue scale over 48 hours, along with analgesia duration, rescue analgesic requirement, diclofenac consumption, patient satisfaction, and adverse events. The Group B demonstrated significantly lower pain scores at all postoperative assessment points, including 24 hours (1.01 +/- 0.63 vs. 2.88 +/- 0.87, p < 0.001) and 48 hours (0.71 +/- 0.42 vs. 1.34 +/- 0.81, p = 0.001). Effective analgesia was significantly prolonged (42.63 +/- 10.58 vs. 21.27 +/- 19.53 hours, p < 0.001), while rescue analgesia and total diclofenac consumption were substantially reduced. Patient satisfaction was higher, with lower incidences of postoperative nausea and vomiting. Ultrasound-guided bilateral SPGB with bupivacaine therefore provided prolonged postoperative analgesia, reduced supplementary analgesic requirements, and supported favorable recovery outcomes following nasal surgery.
