To describe a new technique for vocal cord biopsy involving placement of a laryngeal mask airway (LMA) during general anesthesia and fiberoptic guided biopsy. To report our early experience with this technique. ⋯ The technique has potential advantages over suspension microlaryngoscopy in that it is relatively noninvasive, it allows good airway control with adequate views of the vocal cords, and it facilitates a smooth recovery.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of mivacurium dosage requirements during isoflurane and desflurane anesthesia.
To evaluate the dose requirement and recovery characteristics of mivacurium infusions during anesthesia with equipotent concentrations of either desflurane or isoflurane. ⋯ There were no differences in the dose requirement and recovery indices of mivacurium during either desflurane or isoflurane-based anesthesia. Patients who took longer to recover from the bolus dose in both groups showed a subsequent reduction in dose requirements of mivacurium.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective, randomized comparison of the Flotem Iie and Hotline fluid warmers in anesthetized adults.
To compare the fluid warming capabilities of the Hotline and Flotem IIe devices in surgical patients, and whether warming intravenous (i.v.) fluids with the Hotline device resulted in less hypothermia and less need for other warming methods compared with the Flotem IIe device. ⋯ The Hotline device delivered fluids to the patient at consistently warmer temperatures compared with the Flotem IIe device during actual clinical conditions. This was associated with maintenance of near normal core temperatures throughout the procedure in the Hotline group, and a decreased need for interventions such as forced-air warming and treatment for severe shivering.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol infusion for induction and maintenance of anesthesia in elderly patients: recovery and hemodynamic profiles.
To evaluate the effect of propofol infusion for both induction and maintenance of anesthesia on hemodynamics and recovery in elderly patients compared with conventional thiopental-isoflurane anesthesia. ⋯ Induction of anesthesia by propofol infusion in elderly patients produces greater attenuation of cardiovascular sympathetic response than thiopental bolus induction. Induction and maintenance of anesthesia by propofol infusion results in more rapid recovery in our elderly patients than thiopental isoflurane anesthesia.

Randomized Controlled Trial Clinical Trial
Effect of oral clonidine premedication on anesthetic requirement, hormonal response, hemodynamics, and recovery in coronary artery bypass graft surgery patients.
To examine how premedication with clonidine affects opioid use, hemodynamic effects, hormonal responses, and recovery effects. ⋯ Clonidine decreases opioid use and lowers hormonal response while maintaining stable hemodynamics in patients undergoing CABG with sufentanil anesthesia.
