Influence of preoperative respiratory muscle strength in the postoperative status of patients with heart failure undergoing cardiac surgery. Thaísa Araujo Barreto Bastos, Aracaju, 2011. Respiratory muscles are essential in moving the chest during breathing, allowing entry and exit of air from the lungs to perform gas exchange, and assists in other maneuvers as in cough. It is known that patients with heart failure have reduced respiratory muscle strength evidenced in the evaluation of maximal respiratory pressures and that the studies have associated respiratory muscle dysfunction preoperatively with the presence of pulmonary complications after surgery for some surgeries. The goal of this research was to investigate the influence of preoperative respiratory muscle strength in pulmonary complications in patients with heart failure undergoing cardiac surgery. From March 2009 to September 2010, 40 patients undergoing cardiac surgery at the Cardiology Department of the Hospital Fundação de Beneficência Hospital de Cirurgia were divided into two groups according to the values of maximal inspiratory pressure (MIP) measured by manometer: group A (n = 21) consisted of patients who had MIP normal and group B (n = 19), patients showed a reduction of the measure. For quantitative variables we used the Student t test, whereas for categorical variables and the statistical test chosen was the chi-square test or Fisher's exact test. Also, we performed an analysis of correlation between the variables of gender, functional classification of the New York Heart Association (NYHA), ejection fraction (LVEF), duration of surgery and cardiopulmonary bypass time in the presence of CPP. The level of significance was 5%. Of the patients, 47.5% showed reduction in respiratory muscle strength, the total rate of pulmonary complications after surgery was 25%, 19% of patients in group A and 31.6% of patients in group B had general pulmonary complications, this difference was not statistically significant (p = 0.29). Regarding the presence of specific complications, group A was 14.3% and 10.5% group B (p = 0.55). There was also no difference in the days of ICU stay and total stay between groups. There was a weak association between these variables and the presence of CPP. In this study, preoperative respiratory muscle dysfunction does not seems to influence the evolution of heart failure patients for the presence of pulmonary complications after cardiac surgery. |
