title: Therapeutic lidocaine concentrations have no effect on blood platelet function and plasma catecholamine levels.
abstract: The effects of therapeutic plasma concentrations of lidocaine on blood platelet function and plasma catecholamine levels were assessed in 9 healthy subjects. There were no significant effects on plasma levels of beta-thromboglobulin, collagen and adenosine diphosphate-stimulated platelet aggregation, thromboxane-B2-concentration in plasma after collagen and ADP stimulated platelet aggregation, or on plasma nor-adrenaline and adrenaline. No significant correlation could be demonstrated between any of the variables tested. Thus, it appeared that lidocaine had no effect on platelets that could be of benefit in acute myocardial infarction. It should be possible to use lidocaine, in combination with thrombolytic therapies without increasing the risk of bleeding complications.
