Neuroanesthesia & neurocritical care

The Long-Term Use of Diagnostic Subdural Electroencephalogram Electrodes and Subdural Hematoma: A Prospective Cohort Study*

Crit Care MedPublished Prospective cohort study

  • Trial stopped after a study committee meeting when prespecified criteria were met

Authors' conclusion

Invasive subdural electroencephalogram monitoring is valuable and safe for early seizure/SE detection and treatment and might improve outcomes in the neurocritical care of patients with aSDH.

Study context

Population
Patients with acute subdural hematoma (aSDH) undergoing surgical treatment, neurologic and neurosurgical ICUs of one academic hospital in Germany
Participants

Exposure
Invasive subdural EEG monitoring vs regular surface EEG

  • Controln = 45reference
Outcome
Prevalence and time to seizures and SE occurrence
Methodological detailssingle-center, stopped when prespecified criteria were met

Main finding

As reported in the abstract

Seizure and SE detection

Seizure and SE detection

SE detection

Time to seizure detection, median iEEG 29.2 hr · Control 83.8 hr

Time to SE detection, median iEEG 17.2 hr · Control 83.8 hr

  • iEEG vs Control: P < 0.001
  • iEEG vs Control: P = 0.005
  • iEEG vs Control: P = 0.018 — significantly earlier in iEEG
  • iEEG vs Control: P = 0.033 — significantly earlier in iEEG

Observational data: associations, not effects.

Secondary outcomes

Favorable outcome (GOS 4-5)

P = 0.065

Long-term mortality and post-traumatic epilepsy

No significant differences
