Topical lidocaine effectively reduced the increase of systolic blood pressure after side‐clamping of the aorta in off‐pump cardiac surgery

Background:  Side‐clamping of the ascending aorta during off‐pump coronary artery bypass surgery (OPCAB) may be associated with a significant increase in systemic blood pressure which may rarely result in aortic dissection. We evaluated whether topical application of lidocaine on the ascending aorta could reduce the rise in systemic blood pressure during side‐clamping of the aorta in OPCAB.
