Preliminary Observations on Blood Coagulation Utilizing Ultrasonics for Continuous Measurement of Viscosity *

Studies of coagulation and fibrinolysis by new technic of continuous recording.

ECENT ADVANCES in our knowledge commcerniisg the formatiomi amid dissolution of clots has emphasized the importanice of in vitro coagulation studies imi diagnosis and treatment. These studies geiserally involve one basic observatioms, i.e., the time necessary for the formation or dissolution of a visible clot. Technics based on this observation give no information about the quality of the clot,...

Blood viscosity during coagulation at different shear rates

During the coagulation process, blood changes from a liquid to a solid gel phase. These changes are reflected by changes in blood viscosity; however, blood viscosity at different shear rates (SR) has not been previously explored during the coagulation process. In this study, we investigated the viscosity changes of whole blood in 10 subjects with a normal coagulation profile, using a cone-on-pl...

گزارش سه مورد CVVHD) Continous Venovenous Hemodialysis)

Some of ICU patients with Acute Renal Failure (ARF) require dialysis. Conventional or intermittent hemodialysis (HD) may cause hypotension and insufficient loss of fluids and toxins from blood. Peritoneal dialysis also my cause peritonitis and has lower efficiency than HD. We did continuous Venovenous Hemodialysis (CVVHD) for three ICU patients with ARF in Saint-Zahra Medical Center for the fir...

Ultrasonic Measurement of Coagulation and Fibrinolysis.

Interrelation of blood coagulation and hemorheology in cancer.

Cancer progression is associated with activation of blood coagulation. Blood coagulation process, platelet hemostasis and hemorheological properties were evaluated in patients with solid tumors (n = 27) before and after surgery and in healthy control (n = 20). The main features of blood coagulation process in cancer patients were elevated intensity and shortened period of contact phase of coagu...
