The study showed Shed Mediastinal Blood (SMB) contains high levels of
enzymes that determine cardiac injury and infusion of this blood markedly
increased these levels
There was also increased levels of Plasma Free-Hgb and immature
neutrophils
The authors concluded the results support the idea that SMB
does cause a coagulopathy in some patients and has other
clearly undesirable consequences
Although, the study clearly showed that the authors collected
blood/fluid from the pleural space and this increased the
volume collected from this source rather than the heart and
mediastinum leading to high levels of Free-Hgb, Neutrophils,
and Cardiac enzymes
