Information provided by (Responsible Party):
Lehigh Valley Hospital
  Purpose
A total of 50 patients >40 yrs of age with an expected hospital stay in the Medical Intensive Care or Regional Heart Unit at LVH Muhlenberg of 6 days or longer will be enrolled. The patient and study team will be blinded to which drug they are receiving (either Arixtra or Lovenox). Subjects will be examined for any bleeding complications. Subjects will receive drug for a total of 6-14 days while in the hospital. A follow up phone call will be performed by the study team approximately 30 days after discharge from the hospital.

Condition Intervention
Venous Thrombosis Drug: Arixtra (Fondaparinox) 2.5 mg SC Daily Drug: Lovenox 40mg SC Daily

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Arixtra(Fondaparinux) vs. Lovenox (Enoxaparin) in Prevention of DVT in Acute Medically Ill, Non-surgical Patients

Detailed Description:
A total of 50 patients will be enrolled in this double-blinded, randomized, controlled trial. Inclusion criteria: subjects>40 yrs of age with an expected hospital stay in the Medical Intensive Care or Regional Heart Unit at LVH Muhlenberg of 6 days or longer (4 days bedridden) will be enrolled. Total drug treatment will be 6-14 days while in the hospital. A follow up phone call will be performed by the study team approximately 30 days after hospital discharge. Primary endpoint: bleeding rate (minor vs major) between study days 1-14. Secondary endpoint: DVT study days 1-14 (confirmed with LE duplex ultrasonogram).
