Journal Title: PARIPEX-Indian Journal of Research - Year 2018, Vol 7, Issue 11
Abstract
BACK GROUND AND AIM: The purpose of this study was to compare the efficacy of 0.25% bupivacaine infiltration in the base of anterior tonsillar pillar. for post op pain relief in children aged 7-12 administered after tonsillectomy by submucosal infiltration. MATERIALS AND METHODS: In this prospective study sixty healthy patients in the age group of 7-12 years belonging to ASAGrade1 , scheduled to undergo elective bilateral tonsillectomy surgery for chronic tonsillitis under general anaesthesia, with surgery lasting to 20-40 minutes were included. Follwing surgery and effective hemostasis the control group was infiltrated 0.25% bupivacaine in the base of anterior tonsillar pillar. Pain score was monitored with the help of mCHEOPS (modified Children Hospital Eastern Ontario Pain Score) scale at 0,1,2,3,4,5,6,7&8 hours. RESULTS: The immediate post-op pain relief as measured the mean pain score at 0 hours in the study group was statistically significant[0.5±0.6] to control group[1.8±1.8] with (p=0.0001).The pain relief provided by the block in the first hour in study group was statically significant [1.1±0.9] to control group [6.4±1.6] with (p<0.0001).The duration of pain relief for the study group was significantly higher than the control group[4.5±0.9] to [1.1±0.5] with (p<0.0001 ). The heart rate is significantly lower in the study group compared to the control group for upto 5 hour duration (104.4 ± 6.0 to 107.4 ± 5.8) p=0.05. The heart rate correlates with the post op analgesia provided in the group which received bupivacaine infiltration. There was no complication observed following infiltration in either groups. CONCLUSION: Glossopharyngeal nerve block with 0.25% bupivacaine provides better post -tonsillectomy pain relief in post operative period.
