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.

To evaluate the effects of an intravenous infusion of prostaglandin E1 (PGE1) on hepatic blood flow. ⋯ PGE1 does not affect blood volume shift, CO, or hepatic blood flow.

Randomized Controlled Trial Comparative Study Clinical Trial
A small dose of midazolam decreases the time to achieve hypnosis without delaying emergence during short-term propofol anesthesia.
To evaluate the effect of a small dose of midazolam (10 microg kg(-1)) on induction and emergence during short-term propofol anesthesia and to investigate the effects of subsequent administration of flumazenil. ⋯ Coadministration of 10 microg kg(-1)midazolam decreases the dose and time required to achieve hypnosis with propofol induction without delaying emergence from anesthesia. Additional administration of flumazenil further shortens the time to emerge from midazolam-propofol anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of a continuous glucose-insulin-potassium infusion versus intermittent bolus application of insulin on perioperative glucose control and hormone status in insulin-treated type 2 diabetics.
To compare the effect of two different perioperative insulin management regimes on patients undergoing either major surgery (vascular surgery) or minor surgery (vitrectomy). ⋯ Both regimens resulted in relatively stable and comparable blood glucose levels throughout the perioperative period of the minor and major surgeries without differences in metabolic control as measured by levels of lactate, cortisol, glycerol and free fatty acids. Simplicity would favor the intermittent regimen to manage insulin treated type 2 diabetics.
