Blood Loss, Surgical Clinical Trial
Official title:
Quantification of Blood Loss Using a Novel Device in Comparison to Visually Estimated Blood Loss in a Simulated Blood Loss Scenario
The study´s aim is to evaluate the clinical applicability of the Feature Extraction Technology (FET) during a simulated blood loss scenario.
In an operating theatre blood loss will be simulated in different scenarios. Expired whole
blood donations (provided by the German Red Cross, Institute of Transfusions Medicine, Goethe
University Frankfurt) will be used. Blood will be diluted by full electrolyte solutions .
Sponges and canisters will be prepared with a predetermined amount of blood.
Study participants will estimate total blood loss on sponges and canisters. Study members not
knowing the correct amount of prepared blood will measure the blood loss in sponges and
canisters by Feature Extraction Technology (FET) and by gravimetric method before and after
estimation of the participants.
