Randomized Controlled Trial Clinical TrialLaryngeal mask airway can be inserted with inhaled desflurane induction.
In this prospective, randomized, controlled trial, we investigated the reliability of laryngeal mask airway (LMA) insertion with inhaled desflurane. ⋯ We demonstrated that inhaled desflurane when used with caution in a controlled manner provided acceptable conditions for LMA insertion.

Randomized Controlled Trial Clinical TrialPreadministration of low-dose ketamine reduces tourniquet pain in healthy volunteers.
We evaluated whether preadministration of low-dose ketamine could attenuate tourniquet pain and arterial pressure increase using high tourniquet pressure in ten healthy awake volunteers. Ketamine, 0.1 mg x kg(-1), or normal saline was given intravenously in a double-blind fashion before tourniquet inflation with a pressure of 400 mmHg at the thigh. ⋯ SBP (120 +/- 9 mmHg) significantly increased before tourniquet deflation (133 +/- 16 mmHg) in the saline trial, but not in the ketamine trial. The results show that preadministration of low-dose ketamine attenuates tourniquet pain and arterial pressure increase during high-pressure tourniquet application and prolongs tourniquet time in healthy volunteers.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of fentanyl on emergence characteristics from anesthesia in adult cervical spine surgery: a comparison of fentanyl-based and sevoflurane-based anesthesia.
To evaluate the effects of different anesthesia regimens on bucking, awareness, and pain during the emergence from anesthesia, which may affect neck stabilization and neurological assessment immediately after cervical spine surgery. ⋯ The quality of emergence from anesthesia in patients with cervical spine surgery is improved with fentanyl-based anesthesia, but there is no difference between the use of propofol TCI and less than 1% sevoflurane as a concomitant sedative agent with fentanyl.

Randomized Controlled TrialLandiolol attenuates the cardiovascular response to tracheal intubation.
The objective of this prospective study was to compare the cardiovascular responses with or without landiolol to the induction of general anesthesia and tracheal intubation. ⋯ Continuous administration of landiolol before tracheal intubation results in the attenuation of cardiovascular response for tracheal intubation.

Randomized Controlled Trial Comparative Study Clinical TrialHemodynamic and catecholamine response to a rapid increase in isoflurane or sevoflurane concentration during a maintenance phase of anesthesia in humans.
The purpose of this study was to compare hemodynamic and catecholamine changes due to a sudden increase in inhalation anesthetic concentrations (isoflurane and sevoflurane) during surgery. ⋯ During surgery a sudden increase in isoflurane concentration induced larger changes in hemodynamics and sympathetic nerve activity than sevoflurane.
