To determine the effect of reperfusion of the grafted liver on transcranial Doppler blood flow velocity in the middle cerebral artery in humans during orthotopic liver transplantation. ⋯ MCAVm increased with reperfusion of the grafted liver. These data suggest that multiple factors--including hypercarbia, lactic acidosis, or multiple vasoactive substances released by the grafted liver--may contribute to the observed increases in MCAVm, Vs, and PI.

Randomized Controlled Trial Comparative Study Clinical Trial
Recovery following outpatient anesthesia: use of enflurane versus propofol.
To compare the intraoperative conditions and postoperative recovery of patients following the use of either propofol-nitrous oxide (N2O) or enflurane-N2O for maintenance of outpatient anesthesia. ⋯ Induction of anesthesia with propofol is associated with a more rapid emergence from anesthesia than induction with thiopental. Maintenance of anesthesia with enflurane did not prolong recovery compared with maintenance with propofol, but enflurane was associated with increased frequency of postoperative nausea and vomiting.

Randomized Controlled Trial Clinical Trial
Heated breathing tubes affect humidity output of circle absorber systems.
To verify whether the airway climate in circle systems can be improved with heated breathing tubes. ⋯ Low-flow systems need at least 120 minutes to achieve a satisfactory airway climate. Heated breathing tubes effectively reduce this delay.

To determine whether nitrogen insufflation reduces the laser-induced combustibility of polyvinyl chloride (PVC) endotracheal tube cuffs. ⋯ Nitrogen insufflation decreases CO2 laser-induced PVC endotracheal tube cuff combustibility. However, clinical applications of this technique should be undertaken with caution, as the administration of a hypoxic mixture may be possible.
