Comment Randomized Controlled Trial Comparative Study Clinical Trial[Oral premedication with clonidine in patients undergoing coronary revascularization surgery].
To analyze the effect of premedication with clonidine on level of sedation, anesthetic requirements and hemodynamic repercussions in patients undergoing coronary revascularization. ⋯ Use of clonidine in the type of patient studied does not improve the level of sedation over that achieved with lorazepam. Fentanyl requirements decreased with clonidine. With respect to hemodynamic profile, systemic vascular resistance fell in the clonidine group after removal of ECC, and thus this drug offers no advantages for routine premedication.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study between anesthesia by continuous perfusion with propofol or thiopental-isoflurane in laryngeal surgery].
To compare two anesthetic protocols for maintenance of anesthesia during laryngectomy (propofol vs thiopental-isoflurane), assessing its effects on intraoperative hemodynamic stability and recovery time after withdrawal of anesthesia. ⋯ Propofol for anesthetic maintenance is effective and safe. There are no differences in hemodynamic changes produced by propofol and isoflurane. Time until recovery of consciousness is longer with isoflurane, although we believe that this is not clinically relevant in this type of procedure.
