Randomized Controlled Trial Clinical Trial
Effect of low fresh gas flow rates on inspired gas composition in a circle absorber system.
To determine the effects of fresh gas flow on inspired gas composition during low-flow anesthesia. ⋯ The same initial period of denitrogenation is not adequate to denitrogenate the circle system in all cases. The lower the fresh gas flow, the longer the initial period of denitrogenation should be. Various levels of fresh gas flow for low-flow anesthesia have been suggested, but none guarantees adequate control of inspired gas composition unless flowmeters are continuously adjusted.

Randomized Controlled Trial Clinical Trial
Lidocaine inhalation attenuates the circulatory response to laryngoscopy and endotracheal intubation.
To evaluate the effect of lidocaine inhalation on the circulatory response to direct laryngoscopy and endotracheal intubation. ⋯ Inhalation of lidocaine 120 mg prior to induction of anesthesia is an effective, safe, and convenient method to attenuate the circulatory response to laryngoscopy and endotracheal intubation.

Randomized Controlled Trial Clinical Trial
Elderly patients recover more rapidly from desflurane than from isoflurane anesthesia.
To compare the hemodynamic, emergence, and recovery characteristics of desflurane-nitrous oxide (N2O) anesthesia with those of isoflurane-N2O anesthesia in elderly patients. ⋯ Desflurane may benefit elderly patients by providing a more rapid recovery from anesthesia, leading to a shorter PACU stay.

Randomized Controlled Trial Comparative Study Clinical Trial
Three balanced anesthetic techniques for neuroanesthesia: infusion of thiopental sodium with sufentanil or fentanyl compared with inhalation of isoflurane.
To compare emergence from anesthesia and the hemodynamic and respiratory depressant effects of thiopental sodium infusion plus sufentanil or fentanyl with those of isoflurane as the primary component of a balanced technique for neuroanesthesia. ⋯ Any one of these balanced anesthetic techniques appears appropriate for craniotomy.

Randomized Controlled Trial Clinical Trial
Attenuation of hypertensive response to tracheal intubation with nitroglycerin.
To evaluate the efficacy and safety of intravenous (IV) nitroglycerin in attenuating the hypertensive response to laryngoscopy and intubation as a new application of the drug. ⋯ A single, rapid IV dose of nitroglycerin is a simple, practical, effective, and safe method to attenuate the hypertensive response to laryngoscopy and tracheal intubation.
