Randomized Controlled Trial
Remifentanil decreases sevoflurane requirements in children.
To establish the effect of increasing concentrations of remifentanil on sevoflurane requirements in children. ⋯ The administration of remifentanil produced a dose-dependent decrease in the minimum alveolar concentration of sevoflurane necessary for inhibition of movement reaction in response to surgical incision. The use of remifentanil may allow for flexible analgesic control and rapid recovery in children anesthetized with sevoflurane.

Randomized Controlled Trial
Landiolol and esmolol prevent tachycardia without altering cerebral blood flow.
Several ss-adrenergic-blocking drugs have been used during electroconvulsive therapy (ECT) to stabilize the hemodynamic alterations following electrical stimulation. The effects of two ultra-short acting ss-adrenergic-blocking drugs, esmolol and landiolol, on systemic and cerebral circulation were studied during ECT. ⋯ Landiolol suppresses heart rate elevation during ECT without affecting blood pressure. Cerebral blood flow velocity in the middle cerebral artery is not affected by the use of either esmolol or landiolol.

Randomized Controlled Trial Comparative Study
Infiltration with ropivacaine plus lornoxicam reduces postoperative pain and opioid consumption.
To compare efficacy and patient outcome of wound infiltration with ropivacaine, lornoxicam, or their combination for control of pain following thyroid surgery. ⋯ Wound infiltration with ropivacaine 0.75% plus lornoxicam 8 mg combination improved postoperative pain control and patient comfort, and decreased the need for opioids than the use of either drug alone.

To evaluate the equivalency of the prototype of a new infrared ear thermometer (IRT 4000) in comparison to the temperature measurements of a pulmonary artery catheter (PAC) and a continual contact probe on the tympanic membrane. ⋯ Infrared ear thermometers 4000 temperature readings accurately reflect body core temperature and correlate well with the invasive PAC. Infrared ear thermometers may present a clinically useful alternative to the pulmonary artery thermometry for the measurement of core temperature in the perioperative setting or in the intensive care unit.

To evaluate the magnitude of subjective cognitive failure in the three days following general anesthesia (GA) for ambulatory surgery. ⋯ A statistically significant impairment of cognitive function in the three days following GA, but not LA was found. However, the magnitude of this impairment was small, and is of doubtful clinical significance. Modern ambulatory anesthesia may cause less delayed cognitive impairment than was previously thought.
