Inhaled Sevofluran vs Endovenous Propofol for Colonoscopy

To compare the anesthetic efficacy of the inhalation versus intravenous technique for maintenance of sedation in patients undergoing endoscopy. A longitudinal, randomized clinical study of 32 patients of both sexes ASA I-III, aged 18-80 years undergoing diagnostic colonoscopy, which was randomly divided into 2 groups. In both, intravenous induction with propofol (2-2.5 mg / kg) was performed, Group A remained sedated with propofol infusion (1-2 mg / kg / min); Group B by inhalation with sevoflurane at a concentration of 2 vol% through a nasal cannula with an oxygen flow.
