Post-tonsillectomy infiltration with bupivacaine reduces immediate postoperative pain in children

摘要: Pain management after tonsillectomy in children remains a dilemma for the anaesthetist. A previous study demonstrated that administration of lidocaine 1% topical spray to peritonsillar fossae before tracheal extubation provided considerable immediate postoperative pain relief infants and children. However, was short duration. We were hopeful use bupivacaine would offer more prolonged because its pharmacological characteristics. Therefore, this designed compare effects 0.5% with 1:200,000 epinephrine administered either as or submucosal infiltration on Forty-three patients aged two ten years randomized into three groups performed. Group (1) received 0.5 ml.kg-1 normal saline spray; (2) 2 mg.kg-1 similar volume 1 and; (3) both tonsillar beds. The each group compared postoperatively regard quality control using Objective Score, their analgesic requirements. Peritonsillar superior analgesia reflected by lower recovery room scores (P < 0.05) opioid requirements 0.01). Ward among groups. provides better post-tonsillectomy period than placebo.
