Checklist: Change in Mental Status After Neurosurgery


  • Assess consciousness/responsiveness
  • Assess ABCs, neurologic exam
  • If with focal deficits or signs of increased ICP – perform imaging (noncontrast CT, CTA?, MRI?)
  • Work-up:
    • ABG:  hypercapnea or hypoxia
    • Na, BUN/Crea, Glu, Ca, Mg, Phos
    • CSF studies / infectious work-up
    • EKG, cardiac enzymes
    • continuous EEG
  • withdrawal?  (review history – ETOH, benzodiazepine use)
  • medications?  (review med list – sedatives, analgesics, antipsychotics, anticholinergics)
  • residual effects of anesthesia?

*Residual anesthesia can temporarily unmask predisposition to focal deficit. If this is the case the focal neurologic change will improve with dissipation of anesthetic effects.
