Experience obtained from adenotomy (AT) under general anesthesia using Ketamin hydrochloride (Ketalar, Narkamon) in children are presented in this paper. The authors had used intramuscular premedication with Prothazin, Dolsin and Atropin at the first stage, then they shifted to oral administration of a combination of Diazepam, Theadryl and Atropin. Ketamin may be applied intravenously in the dosage of 1.0 to 1.5 mg/kg of body weight in most children. Where it is not possible, a triple dose into the muscle is used. A total of 2,266 AT were performed. About 70% of patients were calm during the operation, once a suspected aspiration was considered but it was not confirmed. The main contribution of the method is 100% amnesia of the surgery made. The procedure is a compromise between a requirement for minimal traumatization of the child's psyche by the intervention and the resources available, particularly the need of personnel at the majority of otorhinolaryngo-logical departments nowadays.
