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
Laryngeal mask insertion during target-controlled infusion of propofol.
To compare the Laryngeal Mask Airway (LMA; The Laryngeal Mask Airway Co., Ltd., Nicosia, Cyprus) insertion conditions produced by 6 and 8 microg/mL of target plasma concentrations (Cpt) during the induction of anesthesia with target-controlled infusion (TCI) of propofol. ⋯ Induction with 8 microg/mL of Cpt, compared with 6 microg/mL, allowed earlier LMA insertion but, could not improve the conditions for LMA insertion and required more careful attention to the decrease in blood pressure after LMA insertion.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative recovery following outpatient pediatric myringotomy: a comparison between sevoflurane and halothane.
To assess recovery in children undergoing myringotomy and anesthetized using sevoflurane or halothane with special reference to the phenomenon of excitation reported in previous studies. ⋯ Although some studies have reported a high incidence of excitation following sevoflurane anaesthesia, we found no differences between halothane and sevoflurane. This finding could be due to the midazolam given as premedication as well as minimal postoperative pain in these children.

Randomized Controlled Trial Comparative Study Clinical Trial
General anesthesia for interventional neuroradiology: propofol versus isoflurane.
To compare recovery of psychomotor and cognitive ability after isoflurane and propofol-based general anesthesia. ⋯ Both isoflurane- and propofol-based anesthesia allow early extubation and recovery of basic psychomotor functions. More sophisticated tests show a decline of cognitive functions up to 24 hours after isoflurane- as well as propofol-based anesthesia. Because both anesthetics show similar recovery of psychomotor functions after long duration anesthesia, other factors such as subjective well-being and costs may be considered when deciding between these two anesthetics.
