Postoperative pulmonary complications - Still room for improvement.

The intraoperative risks associated with anaesthesia care have significantly decreased over time. However, an increasing number of complications and adverse outcomes are identified during the postoperative period. A recent study using specific trigger tools identified an adverse event rate of 38.1% per 100 discharges from hospital between 2007 and 2011. A significant proportion (40.5%) of these events was associated with surgery and related procedures. These complications increase the likelihood of premature death, up to several years after surgery. Identifying patients at risk, and prevention and appropriate treatment of these complications during the perioperative period, are, therefore, crucial.
