Hemocoagulase for Injection is mainly used for intraoperative and postoperative surgical bleeding reduction and trauma hemostasis. It can be administered intravenously, intramuscularly, or topically. Coagulation function should be monitored during administration to prevent a decrease in efficacy due to excessive doses of the drug. Patients with postpartum hemorrhage who lack platelets and prothrombin factor in their blood need to be given fresh blood before using this product. Clinically commonly used injectable hemagglutinase include: white eyed snake venom hemagglutinase injection, 2KU/pc; spearhead pit viper hemagglutinase injection, 2IU/L.
