Medical Education Network has issued a clarification of a recent report on "Prevention of DVT and PE Following Joint Replacement Surgery: The 1995 ACCP Guideline." The report addressed that aspect of the 1995 American College of Chest Physician's (ACCP) guidelines related to antithrombotic therapy in joint replacement surgery. The clarification states: "While the ACCP guidelines recommend either low molecular weight heparin (LMWH) or intermittent pneumatic compression (IPC) as superior methods for preventing deep vein thrombosis (DVT) following total knee replacement surgery, this does not imply that other pharmacological approaches are not effective as well. Low dose unfractionated heparin and/or warfarin also offer reduction of the risk of developing DVT. It is a matter of individual physician judgment as to what approach is most appropriate on a case by case basis." In an earlier press release, by Medi-Fax, a news service of Medical Education Network, it was stated that, "only LMWH or intermittent pneumatic compression are appropriate for DVT prophylaxis after knee replacement surgery, according to new antithrombotic guidelines issued by the ACCP."
