Preoperative use of enoxaparin is not a risk factor for postoperative bleeding after coronary artery bypass surgery. • A dosage of 40 mg enoxaparin BD instead of 30 mg BD reduces VTE risk but increases bleeding risk. See the dosing and duration of therapy information for the treatment of acute STEMI patients. Enoxaparin administration more than 8 hours before coronary artery bypass surgery is not associated with increased postoperative bleeding or blood product transfusion. An additional 23 consecutive patients who received neither enoxaparin nor heparin served as controls (n = 23). If our blood did not clot, we would be unable to survive even the smallest of injuries, such as a paper cut. Another twenty patients will be randomised to receive the same dose of enoxaparin (40 mg) daily as continuous intravenous infusion for three days (72 hours). Low molecular weight heparins are replacing unfractionated heparin in practice prior to cardiac surgery. Do not place patient on immediate post-procedural IV heparin.
