ABSTRACT

Objective: Comparing the efficacy of inhalatory induction by overpressure technique with 8% sevoflurane vs 5% halothane on the conditions for tracheal intubation in pediatric surgical patients under general anesthesia. Material and methods: A total of 90 patients, aged 2 to 6 years old, ASA 1 and 2, scheduled for elective surgery under general anesthesia, were randomized into this clinical trial.Inhalatory induction was performed by overpressure technique with 8% sevoflurane (study cases) or 5% halothane (controls), in order to compare the adequacy of the conditions for intubation by the Helbo-Hansen, Ravlo and Trap-Anderson measurement system. Results: The quality of the conditions for intubation was optimal in 57.7% of the sevoflurane group, compared to 33.3% in the halothane group (p = 0.05). Induction time was 234.41 ± 124.76 seconds in the study group,and 172.49 ± 62.44 seconds in the control group. Conclusions: The conditions for intubation after inhalatory induction with sevoflurane and overpressure technique showed that induction time with sevofluorane is longer than with halothane;nevertheless, the conditions for intubation were optimal in a significantly higher percentage of patients with sevoflurane vs. halothane
