ABSTRACT
Abstract: Objective: To describe the hemodynamic and respiratory changes during early mobilization (EM) after cardiac surgery. Methods: An analytical observational retrospective cohort study was performed in a Coronary Care Unit of a tertiary hospital. 75 patients submitted to cardiac surgery (From March 2017 up to July 2017) were included. Inclusion criteria were hemodynamic and respiratory stability before starting EM. Hemodynamic and respiratory behavior during EM were evaluated. EM was performed in 3 steps: supine, seated at the edge of the bed (SEB) and biped (BIP). Heart rate (HR), breathing rate (BR), mean arterial pressure (MAP), oxygen saturation (O2Sat) and Borg and Pain scales were evaluated. Results: Six patients, (8%) could not complete the mobilization satisfactorily, which was significantly associated to greater extracorporeal circulation time (ECC T) (p= 0.02). HR, BR, MAP Borg and Pain scales, that were significantly changed during EM, returned fully after the procedure. O2Sat was significantly increased at the end of EM (p=0.000). Prolonged ECC time predicted a 4.6 fold risk for inability to perform EM for 48 hours. Conclusion: EM of patients undergoing cardiac surgery is a safe and feasible intervention. In addition, the prolonged ECC T was observed to be a risk factor for delayed mobilization in this type of patients.
