Chapter 51. Deep Venous Thrombosis Prophylaxis

Introduction

Deep venous thrombosis (DVT) is a common problem in the ICU. Preventative measures include pharmaceutical and physical measures, the latter of which will be covered in this chapter.

Definitions and Terms

• ▪  DVT: Thrombosis in the deep veins of the legs

Techniques

• ▪  Sequential compression devices are applied to the calf or calves in bed-bound critically ill patients (Figure 51-1).

Clinical Pearls and Pitfalls

• ▪  There is some evidence suggesting that sequential compression devices have antithrombotic effects by acting to inhibit the clotting cascade, so that a single sticking may be worn if there is a contraindication to placement on one leg (ie, vascular surgery).
