Randomized Controlled Trial Comparative StudyComparison of two different local anaesthetic infiltrations for postoperative pain relief in tonsillectomy: a prospective, randomised, double blind, clinical trial.
In previous studies, it was shown that the post-tonsillectomy wound infiltration of bupivacaine can reduce postoperative pain. The objective of this study is to determine whether the postoperative wound infiltration with a mixture of bupivacaine, mepivacaine and adrenaline is more effective than the sole application of bupivacaine. A prospective, double-blind, randomized, control study included 30 patients scheduled for "cold steel" tonsillectomy. ⋯ Because of cost-effectiveness and complication rates, we recommend only post-tonsillectomy wound infiltration of bupivacaine. The injection should be placed in superficial muscle and connective tissue. A stringent systemic analgesia regime is indispensable for pain relief after tonsillectomy.
