Status of the anesthesia workforce in 2011: evolution during the last decade and future outlook.

The purpose of this review is to present a comprehensive assessment of the anesthesia workforce during the past decade and attempt forecasting the future based on present knowledge.

Various mechanical problems with the delivery of anesthesia gases have been reported, and preoperative checks of the anesthesia delivery system are designed to prevent these. We report a case of a mechanical obstruction of the expiratory limb of the anesthesia circuit which went undetected before the induction of anesthesia. A check of the circuit was performed before the addition of circuit extensions, thus missing the obstruction.
