1. Routine treatment after replantation (1) isolation nursing, put the patient in a special isolation ward, keep the room temperature at 20 ~ 25℃ and a certain humidity, and strictly disinfect and isolate the system. (2) Raise the limbs. (3) Local heating. (4) Observe the blood circulation of replanted fingers, including color, elasticity, skin temperature and capillary filling time. (5) Commonly used drugs to dilate peripheral blood vessels, such as tolasulin and papaverine. (6) Prevention of infection and routine tetanus. 2. Whether to use systemic anticoagulants after replantation of severed fingers is still controversial. In routine application, it is considered that anticoagulant therapy is helpful to reduce or prevent anastomotic thrombosis. In fact, excellent vascular suture technology is the most important. At present, low molecular dextran, aspirin and some vasospasm drugs are generally used. Anticoagulant therapy such as heparin should be used cautiously only when blood vessels are seriously damaged or thrombi are removed by surgical exploration or blood vessel transplantation.
