Randomized Controlled Trial Comparative Study Clinical Trial[Premedication with clonidine in the neurosurgical patient: sedation, anesthetic requirements and hemodynamic perfusion].
To analyze the effect of premedication with clonidine on postoperative sedation, anesthetic requirements and hemodynamic repercussions in patients undergoing craniotomy due to supratentorial intracranial pathology. ⋯ Premedication of neurosurgical patients with clonidine offers no advantages over lorazepam with respect to sedation. Nevertheless, clonidine may offer advantages with respect to the amount of alfentanyl required and attenuation of perioperative adrenergic response.

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.

Case Reports[Severe accidental hypothermia: rewarming by total cardiopulmonary bypass].
We present a case of a 20-year-old male with a history of habitual drug use who suffered extreme hypothermia (26 degrees C) after several hours' accidental exposure to low ambient temperature. The patient presented in deep coma with recurring ventricular fibrillation that yielded to electrical defibrillation once a central temperature of 27.4 degrees C was reached through internal rewarming with intravenous liquids and gastric lavage with warm water. ⋯ Emergency room staff have available the means for recognizing hypothermia and a protocol for its management. Extracorporeal circulation is an effective method for internal rewarming and must be used when the patient requires cardiopulmonary resuscitation or presents signs of severe hemodynamic instability.
