Randomized Controlled Trial Clinical Trial
Intravenous trimethaphan during epidural plus general anesthesia decreases the direct radial artery pressure lower than the brachial artery pressure.
To determine whether vasodilators such as sodium nitroprusside (SNP) and trimethaphan (TMP) produce a pressure difference between the radial artery and the brachial artery during epidural plus general anesthesia or simple general anesthesia. ⋯ Our results demonstrate that TMP decreases the direct radial artery systolic and mean pressures to levels below the brachial artery systolic and mean pressures in patients who received epidural plus general anesthesia.

Randomized Controlled Trial Clinical Trial
Propofol permits tracheal intubation but does not affect postoperative myalgias.
To determine the effect of propofol without succinylcholine on intubating conditions and postoperative myalgias in ambulatory surgical patients undergoing general anesthesia. ⋯ Propofol did not affect the incidence or severity of postoperative myalgias following succinylcholine.

Randomized Controlled Trial Clinical Trial
Neurocirculatory responses to intubation with either an endotracheal tube or laryngeal mask airway in humans.
To compare the sympathetic and hemodynamic responses to intubation with either an endotracheal tube (ETT) or laryngeal mask airway (LMA). ⋯ Because of the substantial reduction in the neurocirculatory responses to the LMA versus ETT, the LMA may prove advantageous in patients in whom HR and MAP increases may predispose to adverse cardiac or cerebrovascular events.

Evaluation of laboratory coagulation and lytic parameters resulting from autologous whole blood transfusion during primary aortocoronary artery bypass grafting.
To determine if autologous blood reinfusion influences overall hemostatic function following aortocoronary artery bypass graft (CABG) surgery, and if so, where the predominant area of this influence lies. ⋯ Significant improvements in coagulation and lytic parameters occur following CPB after the infusion of autologous blood. These improvements in coagulation indices may be the result of the infused blood or hemoconcentration, which is also known to occur during this period. Additional control studies are needed to differentiate these effects.
