The effect of physiotherapy and pharmacological treatment in preventing thromboembolic disease at hip-near operations was compared from 1971 to 1978 in 787 patients being more than 60 years old. Physiotherapy alone and its completion by Dextran and Acetyl-salicylic-acid turned out to be insufficient. It was only by low-dose Heparin in combination with Dihydroergotamin (Dihydergot) and continuing physiotherapy that the rate of thromboembolism could be lowered effectively.
1971年至1978年期间，对787名60岁以上行髋关节附近手术的患者比较了物理治疗和药物治疗在预防血栓栓塞性疾病方面的效果。结果发现，单独的物理治疗以及用右旋糖酐和乙酰水杨酸辅助治疗均不足。只有通过低剂量肝素联合双氢麦角胺（二氢麦角碱）并持续进行物理治疗，才能有效降低血栓栓塞的发生率。
