Multicenter StudyMulticenter evaluation of the course of coagulopathy in patients with isolated traumatic brain injury: relation to CT characteristics and outcome.
This prospective multicenter study investigated the association of the course of coagulation abnormalities with initial computed tomography (CT) characteristics and outcome in patients with isolated traumatic brain injury (TBI). Patient demographics, coagulation parameters, CT characteristics, and outcome data of moderate and severe TBI patients without major extracranial injuries were prospectively collected. Coagulopathy was defined as absent, early but temporary, delayed, or early and sustained. ⋯ The relative risk for in-hospital mortality was particularly related to disturbed pupillary responses (OR 8.19; 95% CI 3.15,21.32; p<0.001), early, short-lasting coagulopathy (OR 6.70; 95% CI 1.74,25.78; p=0.006), or delayed/sustained coagulopathy (OR 5.25; 95% CI 2.06,13.40; p=0.001). Delayed/sustained coagulopathy is more frequently associated with CT abnormalities and unfavorable outcome at 6 months after TBI than early, short-lasting coagulopathy. Our finding that not only the mere presence but also the time course of coagulopathy holds predictive value for patient outcome underlines the importance of systematic hemostatic monitoring over time in TBI.

Multicenter StudyEarly enteral nutrition and clinical outcomes of severe traumatic brain injury patients in acute stage: a multi-center cohort study.
Guidelines for patients with severe traumatic brain injury (sTBI) published in 2007 recommend providing early nutrition after trauma. Early enteral nutrition (EN) started within 48 h post-injury reduces clinical malnutrition, prevents bacterial translocation from the gastrointestinal tract, and improves outcome in sTBI patients sustaining hypermetabolism and hypercatabolism. The aim of this study was to examine the effect of early EN support on survival rate, Glasgow Coma Scale (GCS) score, and clinical outcome of sTBI patients. ⋯ After adjusting for age, gender, initial GCS score, and recruitment period, the non-EN patients had a hazard ratio of 14.63 (95% CI 8.58-24.91) compared with EN patients. The GCS score during the first 7 ICU days was significantly improved among EN patients with GCS scores of 6-8 compared with EN patients with GCS scores of 4-5 and non-EN patients with GCS scores of 6-8. This finding demonstrates that EN within 48 h post-injury is associated with better survival, GCS recovery, and outcome among sTBI patients, particularly in those with a GCS score of 6-8.
