Abstract
Obesity is a known independent risk factor for deep vein thrombosis and venous thromboembolism (VTE). It is a prevalent condition and its incidence has raised in the last few years, therefore increasing the population at risk of having a venous thrombotic event. After a surgery, VTE is a major cause of preventable death and the effectiveness of thromboprophylaxis is clear. However, the best approach in obese surgical inpatients is not defined. It has been suggested that enoxaparin 40 mg/day is less efficient than 60 mg/day to achieve appropiate anti X activity in obese patients. It is not clear whether higher doses of enoxaparin would also be more effective in preventing VTE, and if this would increase bleeding rates in a clinically meaningful quantity. We conducted a retrospective study to evaluate the real world thromboprophylaxis strategies in obese major surgical inpatients, and to compare enoxaparin doses of 40 mg/day and 60 mg/day in terms of VTE and major bleeding rates.
