BACKGROUND: Acute lung injury (ALI) is a major cause of morbidity and mortality after open thoracotomy. The purpose of the study was to identify the incidence and risk factors for ALI so as to prevent its occurrence and improve surgical results. METHODS: A prospective controlled study was carried out in 364 patients undergone open thoracotomy. Fifty-eight high risk elderly patients and 56 young patients as matched controls were prospectively entered into the study. The two groups were compared to identify the possible risk factors for ALI. RESULTS: ALI occurred exclusively in elderly patients, accounted for 2.7% of the whole series (10/364) and 7.9% of elderly patients (10/127). The mortality for patients with ALI was 30%, significantly higher than those without (1.0%, P=0.001). Upon univariate analysis, increased age, obesity, chronic obstructive pulmonary disease (COPD), poor spirometry, and positive fluid balance on postoperative day 1 were associated with increased risk of developing ALI. Upon multivariate analysis, only poor spirometry and excessive positive fluid balance on postoperative day 1 were revealed as independent risk factors for ALI. CONCLUSIONS: ALI after open thoracotomy has a high mortality. COPD and excessive positive fluid balance on the first postoperative day are significant predictors, suggesting stringent patient selection and timely conservative fluid management may be helpful in reducing this extremely devastating complication.
