Comparison 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.
