Randomized Controlled Trial Comparative Study Clinical Trial
Laryngeal mask airway versus endotracheal tube for outpatient surgery: analysis of anesthesia-controlled time.
To show that efficiency of operating room times can be improved significantly using rapid changes between operative procedures. ⋯ The clinical relevance of reduced anesthesia induction time using LMA is questionable. The lack of difference in emergence time could be a result of the use of total intravenous anesthesia.

This conference reports a case of acute functional airway obstruction occurring in the postoperative anesthesia care unit, which was diagnosed by fiberoptic laryngoscopy and successfully treated with intravenous midazolam after other more common causes of stridor were ruled out. The presentation, etiology, diagnosis, and treatment of paradoxical vocal cord motion as it relates to the care of the postoperative patient are discussed.

The anesthetic of a patient who presented for vascular access under axillary block is described. After physical examination and ultrasound study, the patient was found to have a bifid axillary artery. Because of neurologic anomalies associated with this vascular variation, an interscalene block was chosen for the procedure. The clinical implications of a bifid axillary artery when an axillary block is contemplated are discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, randomized, double-blinded comparison of ropivacaine 0.5%, 0.75%, and 1% ropivacaine for peribulbar block.
To evaluate the efficacy of three different concentrations of ropivacaine (0.5%, 0.75%, and 1%) together with a single concentration of hyaluronidase administered for peribulbar block. ⋯ While confirming that ropivacaine is a good option for peribulbar anesthesia, this study demonstrated that the use of 0.75% or 1% concentrations are preferred in that they produce quick and deep sensory and motor block of the operated eye. If recovery of normal motor function is important after surgery, the 0.75% concentration probably represents the best compromise.
