To evaluate the ability of arterial waveform contour analysis to measure cardiac output (CO) continuously in postoperative critically ill patients. ⋯ The PCCO method appears to be able to estimate changes in CO under the conditions tested, in which PCCO was recalibrated after each TDCO measurement. However, limitations of this method in the immediate postoperative period following aortic aneurysm surgery were identified.

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.
