Randomized Controlled Trial Comparative Study
Fentanyl-induced hemodynamic changes after esophagectomy or cardiac surgery.
The goal of this study was to characterize the hemodynamic response to propofol vs propofol with fentanyl when used for sedation after esophagectomy or cardiac surgery. ⋯ Propofol has a differential effect on hemodynamics and sedation when comparing patients after cardiac surgery and esophagectomy.

Randomized Controlled Trial
Anesthesia with 1.5 minimum alveolar concentration sevoflurane is not altered by physostigmine as measured by bispectral and clinical indices.
To evaluate the effect of physostigmine on 1.5% sevoflurane anesthesia and recovery. ⋯ Physostigmine did not influence BIS values or early recovery when administered to patients anesthetized with 1.5 MAC sevoflurane anesthesia.

Randomized Controlled Trial
The influence of timing of systemic ketamine administration on postoperative morphine consumption.
To determine the influence of timing of systemic ketamine administration on postoperative morphine consumption. ⋯ Lower pain scores and morphine consumption in groups 2 and 3 may be related to higher plasma ketamine concentrations caused by the higher doses and later administration. Our findings suggest that a single preoperative dose of ketamine provided less analgesia compared with other dosing regimens that included intraoperative infusions or postoperative administration.
