To determine the most suitable effect-site concentration of remifentanil during lightwand intubation when administered with a target-controlled infusion (TCI) of propofol at 4.0 μg/mL without neuromuscular blockade. ⋯ A remifentanil effect-site concentration of 2.16 ± 0.19 ng/mL given before a propofol effect-site concentration of 4 μg/mL allowed lightwand intubation without muscle relaxant.

To investigate whether patients with postural orthostatic tachycardia syndrome (POTS) developed unexpected perioperative complications. ⋯ Intraoperative hypotension, but not tachycardia, was observed in three of 13 patients with POTS who received general anesthesia for a variety of surgical procedures using multiple medications and techniques.

Use of a tracheoscopic ventilation tube for endotracheal intubation in the difficult airway.
Difficult endotracheal intubation is a clinical challenge for anesthesiologists and other practitioners of airway management. The use of a tracheoscopic ventilation tube, a novel airway device, for endotracheal intubation during general anesthesia in two patients with difficult airways after unsuccessful direct laryngoscopy is presented.

Repair of a retinal detachment was performed during a retrobulbar block with monitored anesthesia care and intravenous conscious sedation. Following the procedure and after removal of the sterile drapes, the patient exhibited significant swelling of the bilateral orbits, face, neck, and chest. Subcutaneous emphysema and pneumomediastinum were confirmed on postoperative chest radiographs and computed tomographic scans. Possible mechanisms and potential sequelae of this intraoperative event are discussed.
