PURPOSE: This study aims to assess outcomes of pediatric patients with blunt traumatic brain injury (TBI) with a presenting Glasgow Coma Score (GCS) of 3.
METHODS: After local institutional review board approval, we identified patients ages 0 to15 years with blunt TBI and a reported GCS of 3 between 2007 and 2017 from a pediatric level 1 trauma center prospective registry. Exclusion criteria were cardiac death on arrival and penetrating injury. We recorded clinical variables from patients with a non-pharmacologic GCS of 3 and pupillary exam documented by a neurosurgical attending or resident. The original Glasgow Outcome Scale (GOS) was used to compare with other studies. Importance of variables to survival was calculated.
RESULTS: A total of 88 patients (mean age 6.9 years) were included with a mortality rate of 68%. Twelve percent had a poor long-term outcome (GOS 2 or 3) while 20% had a good long-term outcome (GOS 4 or 5). Median follow-up was 1.8 years. Initial group comparison revealed patients in group 1 (survivors) had less hypotension on arrival (14% SBP < 90 mmHg vs. 66%, p < 0.0001), higher temperatures on arrival (36.3 °C vs 34.9 °C, p = 0.0002), lower ISS (29.7 vs 39.5, p = 0.003), less serious injury to other major organs (34% vs 61%, p = 0.02), more epidural hematomas (24% vs 7%, p = 0.04), and less evidence of brain ischemia on CT (7% vs 39%, p = 0.002) or brainstem infarct, hemorrhage, or herniation (0% vs 27%, p = 0.002). Differences between the 2 groups in age, sex, race, MOI, AIS score, presence of midline shift > 5 mm, or time from injury to hospital arrival or time to surgery were not statistically significant. Classification tree analysis showed that the most important variable for survival was pupillary exam; mortality was 92% in presence of bilateral, fixed dilated pupils. The relative importance of initial temperature, MOI, and hypotension to survivability was 0.79, 0.75, and 0.47, respectively.
CONCLUSION: Twenty percent of our pediatric non-pharmacologic GCS 3 cohort had a good functional outcome. Lack of bilaterally fixed and dilated pupils was the most important factor for survival. Temperature, MOI, and hypotension also correlated with survival. The data support selective aggressive management for these patients.
