Abstract :
Hemostasis effected by utilizing whole blood clotting times is difficult because such data currently can be obtained only by lengthy and unreliable means. A rapid new method using a hemotensiometer has been developed that can measure whole blood clotting times accurately. An additional parameter, the clotting strength, can be measured as well. These tests may be performed upon blood that contains no additives or with blood containing anticoagulants such as heparin or buffered citrate. The hemotensiometer has been used successfully to control the dosage of anticoagulants and coagulants in various clinical states. Also, it is useful in diagnosing coagulopathies and following patient recovery from bleeding disorders.
