为预防腹部器官手术后血栓栓塞,除使用物理性预防法(下肢弹性绷带,按摩,早期站立)以外,分组用药物预防。第1组410例,病人有明显的血栓形成体质和DIC症状,术后每4-6小时皮下或静脉注射肝素1次,1昼夜15000-20000单位,共3-5天;同时内服双香豆素类间接抗凝剂10-12天。第2组320例,病人发生血栓栓塞危险性较高,有DIC实验室症状,有容易发生血栓的因素;术后静脉输入肝素合剂(肝素5000单位,胶性葡萄糖盐水400ml,1%烟酸15ml),3-4天以后改用口服间接抗凝剂10-12天。第3组390例,术后只给间接抗凝剂。第4组305例,只给烟酸。第5组278例,只给乙酰水杨酸。第6组375例,认为发生血栓栓塞的危险性很
In order to prevent postoperative thromboembolism in abdominal organs, drug prevention should be done in groups except physical preventive method (lower limb elastic bandage, massage, early standing). The first group of 410 patients, the patient has obvious symptoms of thrombosis and DIC, subcutaneous or intravenous heparin once every 4-6 hours after surgery, 15,000-20000 units a day and night for a total of 3-5 days; while oral administration of double coumarin Class of indirect anticoagulant 10-12 days. The second group of 320 patients, patients with high risk of thromboembolism, DIC laboratory symptoms, there are easy to thrombotic factors; postoperative intravenous heparin mixture (heparin 5000 units, gel saline 400ml, 1% niacin 15ml ), 3-4 days later switched to oral indirect anticoagulant 10-12 days. Group 3 390 cases, only to indirect anticoagulation after surgery. Group 4 305 cases, only niacin. Group 5 278 cases, only acetylsalicylic acid. Group 6 375 cases, that the risk of thromboembolism is very
