Abstract

Venous thromboembolism and pulmonary embolism can be found in covid-19 patients due to hypercoagulable state, requiring anticoagulants in both treatment and prophylaxis. By subcutaneous injection of enoxaparin 40 mg once daily in ICU patients to prevent embolism, some patients presented with localized intramuscular bleeding. Two cases were reported in this study. Patients developed abdominal wall and psoas hematoma at the area of injection. Concerning factors were receiving high dose and the inappropriateness of injection technique. The bleeding potency can be prevented by changing to subcutaneous injection, dose adjustment in renal impairment patients and appropriate anti-Xa monitoring after the 3rd dose in patients who received once daily dosing or after the 3rd or 4th dose in patients who received twice daily dosing. It is recommended that enoxaparin should be subcutaneously injected for at least 30 seconds pushing time and pending the needle about 10 seconds before withdrawal.
