BackgroundIn 40% of the cases, pulmonary complications are encountered after aortic surgery in patients suffering from chronic obstructive broncho-pneumopathy (COBP). The factors aggravating the occurrence of these complications are cumulated tobacco addiction of ≥40 packets per year and surgery for aneurysm. The aim of our prospective study was to evaluate the effect of pre- and postoperative noninvasive ventilation (NIV) preparation on the respiratory function of patients presenting with high pulmonary risks.MethodsBetween September 2007 and May 2010, 30 patients were included in the present study. Inclusions criteria were male gender, patients suffering from COBP with tobacco addiction of ≥40 packets per year, and aortic surgery for aneurysm with or without occlusive lesions. In all, 14 of the 15 patients had effectively performed the preparation before and after surgery according to a fixed protocol (NIV group). We compared the respiratory rate complications and the mean hospital length of stay in intensive care with the non-NIV control group (15 patients).ResultsMean age, severity of COBP according to the classification of the French Society for Pneumology, surgery duration, and blood losses were comparable between the two groups. Conversely, pulmonary complications were significantly lower in the NIV group (0/14 [0%] vs. 5/15 [33%], p = 0.004). Hospital length of stay in intensive care was shorter in the NIV group (2.5 vs. 6.5 days, p < 0.001).ConclusionPreliminary results are encouraging, in favor of pulmonary preparation before aortic surgery with NIV at home, and carried on postoperatively in hospital for patients with COBP. These results prompt us to propose a multicenter study to validate these first observations.Copyright © 2011. Published by Elsevier Inc.
