Abstract


Aim: To compare the hemodynamic effects and myocardial oxygen consumption (MVO 2) during bathing in bed without hydrothermal handling and positioning in the case of patients with acute myocardial infarction (AMI) and not infarcted by thoracic electrical bioimpedance. Method: Clinical, parallel, randomized and controlled trial. The dimensioning of a discrete and finite sample was carried out and the resulting sample is composed of 30 infarcted patients classified as Killip class I or II, admitted to a private hospital, and assisted up to 72 hours after the cardiac event; 30 hospitalized controls with no cardiac cause, matched by age and sex, with pulse pressure <50 mm/Hg. Data processing: SPSS; descriptive and inferential statistical analysis: measures of central tendency, Shapiro-Wilk normality test; ANOVA and Kruskal-Wallis. Significance level of 5%. Conclusion: The results will make a difference for nursing research in order to test the scientific outcomes of the use of a bed bath, and the safety and quality of care provided to infarction patients.
