[Preoperative autologous blood collection under erythropoietin stimulation. Preliminary results in patient selection, erythropoietin dosage and administration].

In a randomised study we have evaluated the influence of erythropoietin (EPO) on the yield of autologous blood in elective surgery (total hip replacement). The study was performed placebo controlled in 82 patients: 25 patients received 200 IE EPO/kg 2 x/week i.v.

Thromboembolic prophylaxis in total hip replacement: a comparison between the low molecular weight heparinoid Lomoparan and heparin-dihydroergotamine.

In a prospective, randomized, assessor-blind multicentre study two antithrombotic subcutaneous regimens were compared in patients undergoing total hip replacement. Group 1 (154 patients) received 750 anti-Xa units of a new low molecular weight heparinoid (Lomoparan) subcutaneously twice a day and group 2 (155 patients) received 5000 units heparin and 0.5 mg dihydroergotamine (heparin-DHE 5000) twice a day.
