To evaluate the effects of early exercise

Abstract: Objective: To evaluate the effects of early exercise intervention in patients who have undergone primary isolated valve surgery.
Methods: Forty patients scheduled for mitral, aortic, and/or tricuspid valve surgery were allocated to receive a supervised exercise intervention consisting of cycling for 3 min/d at the bedside after operation (intervention group, n=20, mean age years) or to receive no exercise intervention (control group, n=20, mean age years). Oxygen saturation (SpO2) was measured by pulse oximetry continuously before and after the 6-minute walk test. Psycho-educational counselling was provided, and patients were assessed using standard patient questionnaires.
Results: The arterial SpO2 level increased significantly in the intervention group after exercise compared with the control group (P < 0.05). Heart rate returned to baseline in the intervention group postoperatively and was significantly lower than that in the control group (P < 0.05).
Conclusions: A small amount of supervised cycling exercise at the bedside is a safe activity that may improve peripheral arterial SpO2 and reduce heart rate to the baseline level following longer distance walk before discharge in patients who have undergone isolated valve surgery.
