Pre-mortem donor interventions may include:

A. Blood testing for donor eligibility (tissue typing, cross match, virology screen and organ function testing)
B. Staged preparation for in situ preservation or extracorporeal oxygenated perfusion, which may include sterile preparation and draping of the surgical field, isolation of femoral vessels by surgical cutdown and cannulation of vessels
C. Pharmacological interventions: administration of anticoagulants (e.g., heparin), arterial vasodilators (e.g., phentolamine) and thrombolytics. To be effective, intact circulation (prior to death) is required for systemic distribution, although some centers administer them after death in the preservation solution.
