Tóm tắt

OBJECTIVES: The goal of this paper is to describe prehospital status and treatment of patients with severe TBI in Austria. PATIENTS AND METHODS: Data sets from 396 patients with severe TBI (Glasgow Coma Scale score < 9) included by 5 Austrian hospitals were available. The analysis focused on incidence and/or degree of severity of typical clinical signs, frequency of use of different management options, and association with outcomes for both. ICU mortality, 90-day mortality, final outcome (favorable = good recovery or moderate disability; unfavorable = severe disability, vegetative state, or death) after 6 or 12 months, and ratio of observed (90-day) to predicted mortality (O/E ratio) are reported for the selected parameters. Chi2-test, t-test, Fisher's exact test, and logistic regression were used to identify significant (p < 0.05) differences for association with survival and favorable outcome (both coded as 1). RESULTS: The majority of patients were male (72%), mean age was 49 ± 21 years, mean injury severity score (ISS) was 27 ± 17, mean first GCS score was 5.6 ± 2.9, and expected hospital survival was 63 ± 30%. ICU mortality was 32%, 90-day mortality was 37%, and final outcome was favorable in 35%, unfavorable in 53%, unknown in 12%. We found that age > 60 years, ISS > 50 points, GCS score < 4, bilateral changes in pupil size and reactivity, respiratory rate < 10/min, systolic blood pressure (SBP) < 90 mm Hg, and heart rate < 60/min were associated with significantly higher ICU and 90-day mortality rates, and lower rates of favorable outcome. With regard to prognostic value the GCS motor response score is identical to the full GCS score. Administration of > 1000 ml of fluid and helicopter transport were associated with better outcomes than expected, while endotracheal intubation in the field had neither a positive nor a negative effect on outcomes. Administration of no or < 500 ml of fluids was associated with worse outcomes than expected. Outcomes were better than expected in the few patients (5%) who received hypertonic saline. CONCLUSIONS: Age, ISS, and initial neuro status are the factors most closely associated with outcome. Hypotension must be avoided. Fluids should be given to restore and/or maintain SBP > 110 mm Hg. Helicopter transport should be arranged for more seriously injured patients.
