In this review, we examine the association between physician professional behaviour and indicators measuring patient outcomes and satisfaction with care as well the potential for complaints, discipline, and litigation against physicians. We also review issues related to the structured teaching of professionalism to anesthesia residents, including resident evaluation. ⋯ A framework is provided for defining behavioural expectations, and mechanisms are offered for teaching and evaluating behaviours and responding to individuals with behaviours that persistently breach defined expectations. There is a need to define explicitly not only the expectations for behaviour but also the processes by which the behaviours will be assessed and documented. In addition, emphasis is placed on the nature, order, and magnitude of the responses to behaviours that do not meet expectations.

Hypotension is common in patients undergoing surgery in the sitting position under general anesthesia, and the risk may be exacerbated by the use of antihypertensive drugs taken preoperatively. The purpose of this study was to compare hypotensive episodes in patients taking antihypertensive medications with normotensive patients during shoulder surgery in the beach chair position. ⋯ Preoperative use of antihypertensive medication was associated with an increased incidence of intraoperative hypotension. Compared with normotensive patients, patients taking antihypertensive drugs preoperatively are expected to require vasopressors more often to maintain normal blood pressure.

Hypotension in the sitting position may reduce cerebral perfusion and oxygenation. We prospectively determined the incidence of cerebral oximetry (rSO2) desaturation in seated patients undergoing ambulatory shoulder arthroscopy. ⋯ Despite frequent hypotension in the sitting position, rSO2 desaturation was uncommon during shoulder arthroscopy performed in the sitting position with regional anesthesia.

Case Reports
Management of a patient with tracheomalacia and supraglottic obstruction after thyroid surgery.
We describe an unusual combination of dynamic supraglottic, glottic, subglottic, and intrathoracic airway obstructions following a total thyroidectomy. These problems were anticipated, documented videographically, and managed preemptively. ⋯ Acute airway collapse following thyroid surgery is a rare and potentially serious complication. Diagnosis by conventional methods may be insensitive. Difficulties may not be apparent until the patient becomes distressed after tracheal extubation, and this circumstance will worsen airway compromise. In such a state, re-establishing the airway can become life-threatening. We describe the preemptive identification, physiologic manifestations, and management of the supraglottic and subglottic obstruction exemplified by this case.
