NATHIRE, MEH et al. Spectrum of coagulation profiles in severely injured patients - a subgroup analysis from the fluids in resuscitation of severe trauma trial. S. Afr. j. surg. [online]. 2023, vol.61, n.1, pp.12-17. ISSN 2078-5151.

BACKGROUND: Trauma-induced coagulopathy (TIC) is a major contributing factor to worsening bleeding in trauma patients. The objective of this study is to describe the spectrum of coagulation profiles amongst severely injured patients METHODS: This is a retrospective study of all patients with complete baseline TEG coagulation parameters collected prior to randomisation in the FIRST (fluids in resuscitation of severe trauma) trial between January 2007 and December 2009. Parameters recorded for this study included patient demographics, mechanism of injury, admission vital signs, lactate, base excess, coagulation studies prothrombin time (PT), international normalised ratio (INR), thromboelastography (TEG) parameters, volume, and type of fluids administered, volume of blood products administered, length of intensive care unit (ICU) stay and major outcomes RESULTS: A total of 87 patients were included in this study, with a median injury severity score (ISS) of 20 and 57.5% had a penetrating injury mechanism. Coagulopathy was highly prevalent in this cohort, of which a majority (69%) was diagnosed with hypercoagulopathy and 24% had a hypocoagulopathy status on admission. There was no difference in age, gender and amount of pre-hospital fluids administered across the three groups. The median volume of blood products was higher in the hypocoagulopathy group, although not statistically significant. Overall, the 30-day mortality rate was 13%, with case fatalities occurring in only coagulopathic patients: hypercoagulopathy (15%) and hypocoagulopathy (10% CONCLUSION: TIC is not an infrequent diagnosis in severely injured patients resulting in increased morbidity and mortality. Determining the coagulation profile using TEG at presentation in this group of patients may inform appropriate management guidelines in order to improve outcome
