OBJECTIVE To verify, in dissection adenotonsillectomy (AT) performed in Rose position under general anaesthesia with oro-tracheal intubation, the following: 1) the ability of tramadol to produce an effective intra- and postoperative analgesia without any considerable side effects or interferences with the normal post-surgical course of the operation; 2) the possibility of obtaining, thanks to mivacurium, a myoresolution closer both to surgical times of the operation and to the necessity of a fast recovering of the pharyngo-laryngeal reflexes. METHODS A perspective and retrospective clinical study. METHODS University clinic department (operating room and facility). METHODS 110 patients submitted to adenotonsillectomy, aged 4-10, belonging to the I-II ASA categories and not taking any drug for at least 30 days. METHODS Intravenous pre-medication with tramadol 2 mg/kg; myoresolution with mivacurium 0.2 mg/kg; postoperative analgesia with tramadol 2 mg/kg i.m. one hour after the first administration and, with an equivalent oral dose of tramadol, six hours later. METHODS During surgery: ECG, HR, Sat HbO2, non-invasive arterial blood pressure; after surgery: clinical evaluation of pain, through a three-point scale, and of the surgical course. RESULTS Good analgesical level both during and after surgery; myoresolution especially suitable to adenotonsillectomy duration and characteristics; no considerable complications. CONCLUSIONS Tramadol intra- and postoperative analgesia and mivacurium myoresolution represents, in personal opinion, an efficient approach to dissection adenotonsillectomy performed in children under general anaesthesia.
