ABSTRACT
The study was carried out in 124 children aged 4-10 years with ASA risk I or II. Group 1 consisted of 40 patients operated on under combined anesthesia with midazolam, fentanyl, and N2O, group 2 were 30 children operated on under mask anesthesia with fluothane, and nitric oxide + oxygen, group 3 patients were operated on under combined anesthesia with ketamine, midazolam, and N2O + CO2, and group 4 patients were operated on under thiopental and N2O + CO2. Cardiovascular function was evaluated by the NCCOM3-R-7 device (BoMed) by the bioimpedance method. Satisfactory cardiovascular function was observed in all groups, but the best stability was noted in the midazolam-fentanyl group. Hence, midazolam-fentanyl combination can be the method of choice in short-term ENT operations.
