Anaesthesia and postoperative pain management for bilateral lung volume reduction surgery

Bilateral lung volume reduction surgery was introduced into Australia in 1995 for treatment of selected patients with emphysema. We present our experience of the anaesthetic management of our first 55 cases and describe factors associated with outcome. There were four postoperative deaths (7%). Mean (SD) total operation time was 231 (72) minutes. Median intensive care unit (ICU) stay was 26 hours. There was a significant improvement in postoperative lung function (FEV₁, VC, 6-minute walk test, all P < 0.001). Eight patients (15%) required intubation for respiratory failure; three of these patients subsequently died. With multivariate analysis, total operative time was the only significant predictor of length of ICU stay R² = 0.25, P = 0.001), which itself was the only significant predictor of hospital stay duration (R² = 0.36, P < 0.001).
