Blood lactate in a cohort of patients with severe penetrating trauma at the intensive care unit in a university hospital

Methods In a retrospective cohort from October 2013 to October 2014 we included patients over 14 years old, admitted by the emergency service with surgical penetrating trauma and attended in the intensive care unit. At least one measurement of lactate at recruitment was required, as well as information on the mechanism of trauma, injured body area, revised trauma score (RTS), APACHE II, length of stay and mortality. The relationship between lactate levels and mortality was established by means of a logistic regression model.
