Randomized Controlled Trial Clinical Trial
Oxygen administration during transport and recovery after outpatient surgery does not prevent episodic arterial desaturation.
To compare the efficacy of two different oxygen (O2) delivery systems in preventing episodic arterial desaturation in the immediate postoperative period. ⋯ Routine O2 administration during transport and PACU stay did not abolish episodic desaturation, even in healthy patients undergoing minor surgical procedures. Given the marked difference in acquisition cost, it would appear that O2 administration by nasal cannula is a more cost-effective alternative for routine postoperative O2 administration in certain groups of patients undergoing general anesthesia for outpatient surgery.

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.

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.

To identify the frequency, outcome, and factors associated with unplanned endotracheal extubation (UE) in the intensive care unit (ICU). ⋯ Patients should be observed closely after unplanned extubation, although many may not require reintubation. Reintubation can be quite difficult, necessitating highly skilled airway management. Attention to associated risk factors may decrease the incidence of both accidental and self-extubation.

To determine whether propofol emulsion, fentanyl, and vecuronium remain compatible and stable when mixed in clinically appropriate concentrations. ⋯ The propofol, fentanyl, and vecuronium mixtures studied were compatible and stable immediately after mixing. Appropriate in vitro compatibility testing is recommended before clinical evaluation of propofol-opioid or propofol-opioid-muscle relaxant mixtures.
