Lidocaine instilled onto to the back of the tongue of a supine subject and aspirated has been reported to provide effective topical anesthesia of the airway. The purpose of this study was to observe endoscopically the fate of lidocaine so instilled and document the efficacy of anesthesia for awake fibreoptic intubation. ⋯ A combination of lidocaine gargles and lidocaine instilled on to the back of the tongue and aspirated provides effective anesthesia of the pharynx, larynx, and trachea for awake fibreoptic intubation.

To determine the plasma concentrations of propofol required to achieve different levels of sedation during monitored anesthesia care. ⋯ Target-controlled infusion of propofol provided easy and safe management of intraoperative sedation, allowing fast and predictable deepening in the level of sedation, while minimizing systemic side effects of intravenous sedation due to the minimal risk of overdosing the drug.

To describes a technique of indwelling interscalene catheter placement and to evaluate its complications. ⋯ Indwelling catheter placement into the brachial plexus sheath as described in this communication was effective and associated with few complications.

Placement of double lumen tubes (DLTs) in both normal and difficult airways may be considerably more difficult than standard laryngoscopy and intubation using standard tracheal tubes. Alternative techniques to place DLTs have not been uniformly successful and alternative tracheal tubes do not provide the versatility afforded by the DLT. We intubated the tracheas of patients undergoing thoracic procedures requiring DLTs with the Bullard laryngoscope (BL) to determine its efficacy and outline its shortcomings. ⋯ The BL appears to be effective in the placing DLT into the trachea of patients.
