[Remifentanil versus dexmedetomidine as coadjutants of standardized anesthetic technique in morbidly obese patients.].

Background And Objectives: Two coadjuvant anesthetic drugs - remifentanil and dexmedetomidine - were compared in terms of anesthetic recovery, arterial pH and PaCO2 evolution, in morbidly obese patients submitted to Capella's surgery.

Methods: Participated in this prospective, randomized and double blind study 92 patients divided in two groups and submitted to standardized anesthetic technique (general/epidural). Remifentanil Group (Group R) and Dexmedetomidine Group (Group D) received continuous intravenous infusion of these drugs (0.
