Glossopharyngeal Nerve Block with Long Acting Local Anaesthetic Agent (Bupivacaine) and It’s Effect on Early Post-operative Period in Adult Tonsillectomy: A Prospective Study

Abstract

We evaluated the benefit of glossopharyngeal nerve block with long acting local anaesthetic like bupivacaine. It was a randomized prospective study. Sixty-four patients were selected and divided into two groups. Group A received bilateral nerve block and Group B received no block. Pain score using Visual Analog Scale (0–100 mm) was assessed at 30 min, 2, 6 and 12 h. In the immediate post operative period pain scores of Group A at rest and swallowing was significantly lower than Group B ( p < 0.001 and p < 0.01). Glossopharyngeal nerve block is an important method of reducing post-tonsillectomy pain.
