Hypertonic Solution in Off Pump Coronary Artery Bypass Graft Surgery

Summary

This is a comparison between Hypertonic versus isotonic solution in a double blind randomized trial for off pump Coronary Artery Bypass Graft (CABG) surgery targeting the left marginal branch. Hypertonic solution should provide better tolerance for heart mobilization with less volume expansion and less drugs.
