Longer Immediate Recovery Time After Anesthesia Increases Risk of Respiratory Complications After Laparotomy for Bariatric Surgery: a Randomized Clinical Trial and a Cohort Study.

Background: We compared the effects of two anesthesia protocols in both immediate recovery time (IRT) and postoperative respiratory complications (PRCs) after laparotomy for bariatric surgery, and we determined the association between the longer IRT and the increase of PRC incidence.

Methods: We conducted the study in two stages: (i) in a randomized controlled trial (RCT), patients received either intervention (sevoflurane-remifentanil-rocuronium-ropivacaine) or control protocol (isoflurane-sufentanil-atracurium-levobupivacaine). All patients received general anesthesia plus continuous epidural anesthesia and analgesia.

[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.
