Heparin Resistance and Its Occurrence in Patients Older than 65 years Operated with the Use of Extracorporeal Circulation
Abstract
Heparin resistance occurs in about 20% of population. In that case, after application of a usual dose of heparin (2-3mg/kg) ACT will not be sufficiently extended.
Aim: To determine the real incidence of heparin resistance in patients scheduled for a cardiac surgical procedure. To determine whether there is an association between preoperative treatment with heparin and the incidence of heparin resistance.
Also, to establish whether there is an association between platelet count, patients´ age, and heparin resistance.
