Thromboembolic Prophylaxis and Viscosity Reduction with Ancrod [PDF]

Thrombosis and Haemostasis, 1977
Blood and plasma viscosity were measured at high shear rates in 10 patients receiving intravenous ancrod and 9 patients receiving subcutaneous ancrod. In both groups significant viscosity reduction accompanied fibrinogen depletion and there was no significant fall in haematocrit. Blood and plasma viscosity were also significantly reduced in 28 patients
