[Hemodynamic and metabolic evaluation of dexmedetomidine and remifentanil continuous infusion in videolaparoscopic cholecystectomy: comparative study].

Background And Objectives: Dexmedetomidine has been used for sedation and as coadjuvant drug in general anesthesia. This study aimed at evaluating cardiovascular and sympathetic-adrenal responses to tracheal intubation and pneumoperitoneum inflation with dexmedetomidine, as compared to remifentanil during anesthesia with sevoflurane for videolaparoscopic cholecystectomy.

Methods: Forty two physical status ASA I or II patients, aged 25 to 55 years, were randomly distributed in two groups: GI and GII.
