Abstract
The efficacy of combined dihydroergotamine and heparin (DHE-heparin) medication (2500 IU sodium heparin and 0.5 mg DHE, both given subcutaneously twice daily) or low doses of heparin (5,000 IU of sodium heparin given subcutaneously thrice daily) in preventing postoperative thromboembolic complications was investigated in a prospective, randomized trial in 125 patients over the age of 40 years undergoing elective major gynecological surgery. The I125-fibrinogen uptake test was used for the diagnosis of deep vein thrombosis. There was no statistically significant difference in the incidence of thromboembolism between the groups. Major bleeding occurred less often (p < 0.05) in the DHE-heparin group.
