The study will be prospective, double-blind, randomized study of 40 children aged ≥ 4 and ≤ 12 years undergoing tonsillectomy under general anesthesia.
Patients will be allocated into two groups. Group 1 patients will receive tramadol 2 mg / kg intravenously and saline 0.9% infiltration in tonsils; group 2, will receive tramadol 2 mg / kg infiltration and intravenous saline.
There will be evaluated: postoperative pain intensity by facial scale, supplementary analgesics and interleukin-6. For statistical analysis of the results will be used parametric and nonparametric tests, taking into account the nature of the variables. The level of statistical significance will be set at < 0.05.
