Pulmonary Effects of Anaesthesia and Surgery
It has been appreciated for many years that anaesthesia and surgery exert a deleterious effect on pulmonary function, both during and after surgery. The alveolar-arterial oxygen gradient ((A-a)DO2), is increased during anaesthesia, and may remain elevated for some days postoperatively. Such an elevation of the (A-a)DO2 may be the cause of significant hypoxaemia, especially in the elderly, or those with disordered pulmonary function.
