Sampling MethodNon-Probability Sample
Study Population

Patients will be recruited from the population of severe TBI patients clinically judged to require neurosurgical intervention who present through the emergency department or upon direct transfer to the neurosurgery service at Hennepin County Medical Center. The target sample size for this preliminary study is 10 subjects.

You may qualify if:

  • Patient recommended to undergo craniectomy or craniotomy for the treatment of acute TBI

You may not qualify if:

  • Wound determined to be contaminated
  • Decompression is performed only in the posterior fossa
  • Known systemic infection
  • Pregnancy
