- Abstract
Background: Low molecular weight heparin has proven to be safe and effective but is not without potential risks such as spontaneous bleeding in the abdominal cavity. There is limited evidence evaluating the true incidence of this potential risk and the available literature is primarily via case reports. Case summary: The purpose of this study was to identify the incidence and risk factors associated with enoxaparin use (prophylaxis or treatment) abdominal hematomas in a 350-bed community hospital during an 8-month time period. A total of 44 patients were identified as clinically significant bleeds receiving enoxaparin treatment or prophylactic therapy. Ultimately, 25 patients were excluded from the analysis due to an external cause of the abdominal hematoma or a temporal mismatch in enoxaparin administration and hematoma formation. After exclusion, there were a total of 19 patients that were assessed for the risk factors such as age, gender, renal function, and weight. After evaluation of risks, over half of the patients developing a clinically significant bleed were considered elderly (>65 years of age) and impaired renal function with a creatinine clearance of 60ml/min or less. Conclusion: Patients at risk for an enoxaparin associated hematoma include female patients with a CrCl <60ml/min and/or BMI >30 kg/m2 receiving enoxaparin treatment dosing.
