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.

Clinical Trial Controlled Clinical Trial
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.

To determine the effects of magnesium sulfate on neuromuscular transmission in parturients. ⋯ In this patient population, clinically relevant infusions of magnesium sulfate produced significant changes in neuromuscular transmission as manifested by loss of treppe phenomenon and diminished TOF response to ulnar nerve stimulation.
