Effect of Severe Trauma on PD1 and Its Legend (PD1/L1) on T Lymphocytes and Correlation With Mortality

Unlike neuro-endocrine response to trauma; posttraumatic immune alterations are not easily carried out at bedside. The majority of trials were conducted in the intensive care usually hours to days post injury. In this trial the investigators sought assess the immune responses during emergency department trauma resuscitation by looking at the biomarkers of severe injury by comparing T lymphocytes and programmed cell death molecules and its relation with mortality.
