title: Thromboplastin activity of blood monocytes after total hip replacement.
abstract: Thromboplastin activity of monocytes from blood of seven patients with total hip replacement was investigated. At 24 h and 48 h after surgery, thromboplastin activity was significantly increased compared to the activity before surgery. Thromboplastin activity of endotoxin-stimulated monocytes was significantly increased at 24 h after surgery. There were no significant changes in Factor V after surgery, Factor VII was significantly lowered at 24 h after surgery, while Factor VIII and fibrinogen were significantly increased at 72 h after surgery. The results indicate that monocyte thromboplastin may be a thrombogenic factor after total hip replacement surgery.
