An update on survival after anoxic brain injury in adolescents and young adults

ABSTRACTWhile much is known about long-term survival after traumatic brain injury, less is known about survival after anoxic/hypoxic brain injury. We previously compared the two and found no significant difference (hazard ratio [HR] 0.97, p=0.92) after controlling for age, sex, and severity of disability. The present study updates this, based on 1,802 patients with TBI and 380 with anoxic, aged 15 to 25, evaluated in 1986 or later, and who survived one year post injury. The anoxic group had higher mortality (HR = 1.13), though again the difference was not statistically significant (p=0.58).
