Abstract :

BACKGROUND: The use of topically applied local anaesthetics is an important component of atraumatic administration of regional anaesthesia. This study was designed to compare the efficacy of topical application of 4% Lignocaine and 0.5 % Bupivacaine in reducing post–operative pain after tonsillectomy.

MATERIALS AND METHODS: 105 ASA I / II patients in the age group of 8–35 years admitted to undergo elective Adeno tonsillectomy in a tertiary care hospital were included. The patients were randomly allocated into 3 groups of 35 each. Group N –control Group where normal saline was used, Group L– 4% Lignocaine was used and in Group B 0.5% Bupivacaine was used. The postoperative pain scores were observed in all three groups for a period of 8 hours. Visual Analogue Scale was used for pain assessment. Postoperative pain score was lower in Group L and Group B when compared with Group N.

RESULTS: The overall VAS scores were low in Group L (2.5714 ± 0.6289) than in Group B (4.1000 ± 0.4296) and Group N (4.7357 ± 0.7147) which is statistically significant (P < 0.0005).

CONCLUSION: Topical application of 4% Lignocaine and 0.5% Bupivacaine in the tonsillar bed is an effective method of reducing postoperative pain in patients undergoing elective Adeno tonsillectomy.
