Abstract

Aim. The aim of this study was to examine the effect of early mobilization on hemodynamic parameters in patients undergoing coronary artery bypass graft (CABG) surgery.

Background. CABG is one of the most common surgeries that can increase quality of life and reduce mortality in most cases. It seems that early mobilization of patients from bed may reduce complications after surgery. The most important concern regarding early mobilization is the possible effect on hemodynamic parameters based on which this important intervention is neglected.

Method. In a clinical trial with 100 patients who were candidate for CABG. The patients were randomly assigned to experimental and control group. The experimental group were mobilized from bed in the first, second and third day after surgery. The control group received the hospital routine treatments and mobilization was done in the third day after the operation. The effect of early mobilization on hemodynamic parameters were compare between the groups. Other treatment programs were the same for both group. Data were analyzed in SPSS version 18 and using independent t-test, Chi-square and ANOVA statistical testes.

Findings. There was no statistically significant difference between groups regarding demographic variables and underlying diseases. In the experimental group, blood pressure was higher in the second and third days  compared with that control group. Chest tube drainage on the third day were 495±241 ml for experimental group and 556±285 ml for the control group, and no statistically significant difference was found between the groups in terms of chest tube drainage. None of the patients showed any complication during the mobilization.

Conclusion. The experimental group experienced a minimal increase in blood pressure, but it was not clinically significant. The results of this study indicate that early mobilization from bed in patients undergoing coronary artery bypass graft is a safe and applicable intervention, and don’t increase bleeding and acute hemodynamic changes.
