Randomized Controlled Trial Clinical Trial
Dose response to nitric oxide in adult cardiac surgery patients.
To determine the dose responsiveness to nitric oxide in adult cardiac surgery patients, especially in those patients with pulmonary hypertension. ⋯ Treatment with nitric oxide was associated with significant reductions in PVR in all groups. Dosages higher than 10 ppm were not associated with greater reductions in pulmonary vascular tone. In view of the fact that nitric oxide-related toxicity is dose-related, doses greater than 10 ppm do not appear to be justified in this patient population.

Randomized Controlled Trial Clinical Trial
Body warmer and upper extremities position affect the accuracy of cutaneous thermometers during anesthesia.
To evaluate whether axillary skin temperature can accurately reflect distal esophageal temperature. ⋯ At 0 degrees of arm adduction, or at 90 degrees using the upper body, forced-air surface warmer, axillary skin temperature accurately identified the core temperature in patients during general anesthesia.

Randomized Controlled Trial Clinical Trial
Comparison of the lightwand technique with direct laryngoscopy for awake endotracheal intubation in emergency cases.
To clarify the efficacy of the lightwand technique compared with that of the conventional laryngoscopic technique for awake endotracheal intubation in patients requiring emergency surgery. ⋯ The lightwand technique produces less magnitude of stress following tracheal intubation than does the conventional laryngoscopic technique for awake intubation. Lightwand-assisted awake intubation is thought to be a useful means for induction of anesthesia in cases of emergency surgery.

Clinical Trial
Bispectral analysis during cardiopulmonary bypass: the effect of hypothermia on the hypnotic state.
To evaluate the hypothesis that the bispectral index (BIS) is not affected by the hypothermia that is associated with cardiopulmonary bypass (CPB). ⋯ Hypothermia decreases the BIS by 1.12 units per degree Celsius decline in temperature.

To identify factors that may influence the implementation of acute pain management guidelines in hospital settings. ⋯ Resource availability significantly influences the implementation of pain management practice guidelines in hospital settings. Implementation is often incomplete because various factors affect the feasibility of individual guideline elements and may explain the varying results that guidelines have had on clinical practices.
