Randomized Controlled Trial Clinical Trial
The effect of cricoid pressure application on airway patency.
To assess the incidence of upper airway obstruction associated with the application of cricoid pressure (Sellick's maneuver) by experienced anesthetists. ⋯ The use of manual cricoid pressure, even by experienced anesthetists, causes a degree of airway obstruction and can cause complete airway occlusion.

Comparative Study
Cardiac output measurement: lack of agreement between thermodilution and thoracic electric bioimpedance in two clinical settings.
To determine the agreement between thermodilution (TD) and thoracic electric bioimpedance (TEB) techniques in cardiac output (CO) measurements in hyperdynamic kidney recipients and normodynamic patients subjected to radical cystectomy. The main objective was to determine the reliability of TEB in CO measurement. ⋯ These findings demonstrate lack of agreement between TEB and TD in CO measurements in a hyperdynamic and a normodynamic clinical setting. It is concluded that the TEB device is unreliable in CO measurement and cannot replace or be interchanged with TD.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of preincision versus postincision infiltration with bupivacaine on postoperative pain.
To compare the efficacy of preincision wound infiltration with bupivacaine to wound infiltration at the end of the operation. ⋯ Wound infiltration, either preincision or postincision, had no clinically significant effect on the pain scores or analgesic requirements following abdominal hysterectomy.
