The objective of this study was to examine the utility of the transesophageal echo-Doppler device in evaluating hemodynamic changes during laparoscopic cholecystectomy. ⋯ The transesophageal echo-Doppler device can be used during laparoscopic cholecystectomy. The LV function, as determined by measurement of CI and maximum acceleration, was preserved during laparoscopic cholecystectomy despite significant increases in afterload (ie, MAP and SVR).

Comparative Study
Differential effects of propofol on cerebrovascular carbon dioxide reactivity in elderly versus young subjects.
To examine the age-related difference between elderly and young patients in the effect of propofol on cerebrovascular carbon dioxide (CO(2)) reactivity. ⋯ Cerebrovascular CO(2) reactivity in elderly patients was lower than that in young patients at a propofol dosage of 5 mg/kg/h.

To determine the postoperative outcome of narcolepsy patients, a population that may be at increased risk of perioperative complications, including postoperative hypersomnia, prolonged emergence after general anesthesia, and apnea. ⋯ Pharmacological therapy for narcolepsy should be continued during the perioperative period. In addition, treated narcolepsy patients are at no increased risk for postoperative complications.

Meta Analysis Comparative Study
The effectiveness of rescue antiemetics after failure of prophylaxis with ondansetron or droperidol: a preliminary report.
To compare the effectiveness of treating established postoperative nausea and vomiting (PONV) with an antiemetic acting at a different receptor with that of treating PONV with the antiemetic used for prophylaxis. ⋯ In patients who failed prophylaxis with ondansetron or droperidol, promethazine was significantly more effective than the agent used for prophylaxis for the treatment of PONV. In patients who failed prophylaxis with droperidol, dimenhydrinate was also more effective than droperidol for the treatment of established PONV in the postoperative anesthesia care unit.
