Purpose: This study analyzes the use of a standard nomogram that can help reduce the level of anticoagulation preoperatively to effectively manage perioperative heparin therapy in chronically anticoagulated oral surgery patients who are at high risk for thromboembolism.Patients and Methods: Twenty patients with significant cardiovascular disease, ranging in age from 56 to 79 years and requiring oral surgery, were randomly divided into 2 groups. All patients were on chronic warfarin therapy, and perioperative heparinization was recommended by their cardiologist. Group A (n = 10) had their anticoagulation therapy managed with the use of a standard nomogram. The heparin therapy for group B (n = 10) was managed without the use of the nomogram. The records of all patients were analyzed for therapeutic efficacy of heparinization, number of laboratory tests required, duration of hospitalization, and complications related to heparinization.Results: Patients in group A did significantly better in all parameters when compared with group B patients. There were no complications in group A, whereas there was a 20% incidence of complications related to anticoagulation therapy in group B.Conclusions: The use of a standard nomogram to manage anticoagulation therapy in the oral surgery patient requiring heparinization is strongly recommended. This provides optimal therapeutic benefit, decreases the incidence of complications, and makes the hospitalization less costly and more comfortable for the patient.
