Comparison of effects of Sitting-up using Rope Ladder versus Manual Supported Sitting-up on Haemodynamic Variables in Patients after Coronary Artery Bypass Grafting
Background: Rope ladders are provided to patients to sit-up after cardiac surgery. Sitting-up using rope ladder requires a combination of isotonic and isometric efforts. Combined isotonic and isometric activities cause some cardiovascular/hemodynamic alterations.
Method: Study was conducted on 2nd post-operative day. Measurement of Heart Rate (HR), Systolic Blood Pressure(SBP), Diastolic Blood Pressure(DBP), Rate Pressure Product(RPP) and Post-operative pain were obtained for all subjects in supine, immediately on sitting-up, after 5 minutes and 10 minutes of sitting with either using rope ladder or manual support.
Results: Sitting-up using rope ladder immediately resulted in an increase in DBP, HR and Postoperative pain scores and decrease in SBP and RPP. The significance level was set at p< 0.05.
Conclusion: Sitting-up using rope ladder results in slightly greater alterations in hemodynamic variables.
