Anestesia para colonoscopia: anestesia inhalatoria con sevoflurano frente a anestesia intravenosa con propofol

introduction: the exploratory endoscopy and colonoscopy are now increasingly common, both clinical prescription, and for colon cancer screening, needing anesthesia / sedation in virtually all cases. the most commonly used is intravenous propofol, which in some cases cannot be performed, and an alternative is inhaled. objective: to compare the characteristics of a standard technique with propofol (a) and an inhalation with sevoflurane (b). subjects and methods: we studied the characteristics of both techniques in two groups of 150 patients each, valuing the benefits of each, complications, tolerance, recovery time, acceptation by the endoscopist and the patient for both techniques. results: in both techniques few complications, the degree of tolerance is good / very good in 99% of the group (a), compared to 97% of the group (b). discussion: although we found no publications comparing both techniques in anesthesia for colonoscopy, the use of sevoflurane has been shown similarly favorable characteristics in patients contraindicated for use of propofol, whenever we change the pattern of intravenous anesthesia by inhalation. conclusion: both techniques are equally useful and reliable and can be used with sevoflurane inhalation technique in patients if the propofol is inappropriate, with equal performance and versatility.
