Better clinical outcomes are achieved Current Opinion in Anaesthesiology 2009, in high-volume hospitals and when procedures are performed by a thoracic surgeon. 22:61–67 Postthoracotomy ALI has become the leading cause of operative death, its incidence has remained stable (2–5%) and earlier diagnosis can be made by assessing the extravascular lung water volume with the single-indicator dilution technique. The pathogenesis of ALI implicates a multiple-hit sequence of various triggering factors (e.g. oxidative stress and surgical-induced inflammation) in addition to injurious ventilatory settings and genetic predisposition. Summary Knowledge of the perioperative risk factors of major complications and understanding of the mechanisms of postthoracotomy ALI enable anesthesiologists to implement ‘protective’ lung strategies including the use of low tidal volume (VT) with recruitment maneuvers, a goal-directed fluid approach and prophylactic treatment with inhaled b2-adrenergic agonists.
