Abstract:
Seventy-six patients with severe isolated head trauma (GCS score of 7 or less) were prospectively studied in order to valuate the prognostic power of the APACHE II system. In nonsurvivor patients the APACHE II score was higher than in survivor patients (24.7 +/- 3.2 (SD) vs 18.7 +/- 3.1; p less than .001). With an APACHE II cut-off point of 20 the sensitivity was 100% and the specificity was 70% while a cut-off point of 21 the sensibility decreased to 97.2% but the specificity increased to 72.5%. We conclude that the APACHE II is an effective mean to predict the prognosis of severe brain-injured patients.
