Study Description
Brief Summary:
The purpose of this study is to evaluate the analgesic effect and IL-6 after tramadol infiltration or intravenous for tonsillectomy.

Condition or disease Intervention/treatment
Postoperative Pain Drug: Tramadol 2mg/kg Drug: Saline solution

Detailed Description:

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.
