Interindividual variation in platelets and the cardiovascular response to haemorrhage in the pig.

The platelet count varies two-fold among healthy individuals. Considering the haemostatic role of platelets, this study evaluated the relation between cardiovascular and metabolic responses to uncontrolled haemorrhage and the pretrauma platelet count in pigs. A laceration liver injury was inflicted in 19 pigs (34 ± 3 kg; mean ± SD).
