Administration of protamine through radial arterial access: A prospective observational study

Abstract

Protamine is mainly used to reverse the anticoagulant effect of heparin after cardiopulmonary bypass (CPB). Unfortunately, it is associated with adverse clinical reactions ranging from minor cardiopulmonary instability to fatal cardiovascular collapse. In the present prospective observational study, effects of protamine administration through peripheral intra-arterial route, i.e., radial artery, were investigated.
