Abstract
BACKGROUND AND OBJECTIVES: Functional Endoscopic Sinus Surgery (FESS), septoplasty, submucosal resection of nasal septum, polypectomy are the commonly performed nasal surgeries. Peripheral nerve blocks provide superior pain control during surgery and post operative period and devoid of side effects like somnolence, nausea and vomiting. They also attenuate the stress response following surgery. MATERIALS AND METHODS: A total of sixty patients were taken up for the study. They were randomly divided into two groups, Group A received topical anaesthesia followed by General anaesthesia and Group B received Topical anaesthesia followed by General anaesthesia and then bilateral nerve block of Anterior Ethmoidal nerve and Infraorbital nerve prior to surgery. The comparison of analgesic efficacy was done based on the intraoperative and post operative haemodynamics, postoperative pain scoring by Visual Analogue Scale (VAS) and need for rescue analgesia. RESULTS: Patients who received topical anaesthesia combined with the nerve block (Group B) were found to have good perioperative haemodynamic stability, reduced post operative pain and reduced need for rescue analgesia when compared to the patients who received topical anaesthesia alone (Group A).There was a statistically significant difference between both the groups with p<0.05 in the postoperative haemodynamics, post operative pain (visual analogue scale) and need for rescue analgesia. CONCLUSION: The Anterior ethmoidal nerve block and Infraorbital nerve block with Bupivacaine given preoperatively in combination with the topical anaesthesia provided more haemodynamic stability in perioperative period, reduce the postoperative pain and the need for rescue analgesia when compared to topical anaesthesia alone in nasal surgeries done under General anaesthesia.
