Acute cardiac care & resuscitationCohort study

Combined short- and mid-latency SSEP amplitudes for early prediction of favorable neurological recovery after cardiac arrest

ResuscitationPublished

  • retrospective cohort study

Authors' conclusion

Quantitative assessment of the P25-N30 amplitude within 24 h after cardiac arrest was associated with favorable neurological outcome and may contribute to early multimodal prognostication.

Study context

Population
Comatose adult cardiac arrest patients treated with targeted temperature management between 2009 and 2023 who underwent SSEP recording within 24 h after return of spontaneous circulation (ROSC)29 (40%) achieved favorable neurological outcome
Participants
73 patients
Exposure
P25-N30 amplitude vs N20-P25 amplitude

Main finding

As reported in the abstract

Cortical SSEP amplitudes by outcome
  • Cortical SSEP amplitudes were consistently higher in patients with favorable outcomes

Observational data: associations, not effects.

Addition of non-SSEP predictors

The addition of non-SSEP predictors did not significantly improve overall discrimination
