Resumo: | OBJECTIVES: Cardiac surgery (CC) determines systemic and pulmonary changes that require special care. Awareness of the importance of respiratory muscle dysfunction in the development of respiratory failure motivated several studies conducted in healthy subjects to assess muscle strength. These studies were carried out by evaluating the maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) values. This study examined the concordance among the values predicted by the equations proposed by Black & Hyatt and Neder, and the measured values in cardiac surgery (CS) patients. METHODS: Data were collected from preoperative evaluation forms. The Lin coefficient and Bland-Altman plots were used for statistical concordance analysis. The multiple linear regression and analysis of variance (ANOVA) were used to produce new formulas. RESULTS: There were weak correlations of 0.22 and 0.19 in the MIP analysis and of 0.10 and 0.32 in the MEP analysis, for the formulas of Black & Hyatt and Neder, respectively. The ANOVA for both MIP and MEP were significant (P <0.0001), and the following formulas were developed: MIP = 88.82 - (0.51 x age) + (19.86 x gender), and MEP = 91.36 - (0.30 x age) + (29.92 x gender). CONCLUSIONS: The Black and Hyatt and Neder formulas predict highly discrepant values of MIP and MEP and should not be used to identify muscle weakness in CS patients. |
