Objective:
Extracorporeal membrane oxygenation is a rescue therapy for patients with severe lung failure. Major complications caused by extracorporeal membrane oxygenation are bleeding, thrombosis, and hemolysis. The aim of this study was to compare the impact of different extracorporeal membrane oxygenation systems on blood hemostasis in adults during veno-venous extracorporeal membrane oxygenation therapy.
Design:
Single center prospective randomized study.
Setting:
University Hospital Regensburg, Germany.
Patients:
Adult patients with severe acute respiratory distress syndrome requiring veno-venous extracorporeal membrane oxygenation therapy.
Interventions:
None.
Measurements And Main Results:
Three different extracorporeal membrane oxygenation systems: the Cardiohelp system (Maquet Cardiopulmonary AG), the Dideco ECC.O5 (Sorin Group), and the Deltastream system with Hilite 7000 LT + DP3 pumphead (Medos Medizintechnik AG) were compared. Therefore hemostasis, anticoagulation, hemolysis, and inflammatory parameters were monitored. Of the 54 patients included in the study, 18 patients each were randomly assigned to the three different extracorporeal membrane oxygenation systems. Exclusion criteria were acute renal failure, trauma, and surgery within 2 days. The median time on veno-venous extracorporeal membrane oxygenation support was 13.5 days (4-70 d). Median platelet count had dropped from 220.5 G/L before extracorporeal membrane oxygenation therapy to a minimum of 133 G/L by the last day of extracorporeal membrane oxygenation support. During the first 5 days of extracorporeal membrane oxygenation therapy, prothrombin fragment 1.2 (F1.2) (1.36-2.4 µM), thrombin-antithrombin complex (14.5-50 µg/L), and D-dimers (6.00-27.0 mg/L) increased, whereas fibrinogen values dropped from 5.8 to 4.1 g/L. The three different extracorporeal membrane oxygenation systems did not show any differences with regard to hemostasis, anticoagulation, hemolysis, and inflammatory parameters within the first 5 days of extracorporeal membrane oxygenation therapy.
Conclusions:
Over time, miniaturized veno-venous extracorporeal membrane oxygenation therapy increasingly activates coagulation. The different types of membrane oxygenators and pumps did not significantly alter hemostasis.

01:20Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves...

Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
