N20-P25 Amplitude can Predict Awakening from Coma.

ABSTRACT:

Background

The objective of this study was to evaluate the relationship between the N20-P25 amplitude of short-latency somatosensory evoked potentials (SSEPs) and neurologic outcomes in patients in a coma state.

Methods

We retrospectively enrolled neurocritical patients who were older than 18 years; were admitted to the Department of Critical Medicine, Xiangya Hospital, Central South University, from January 2017 to January 2021 for 1-3 days; had a Glasgow Coma Scale score ≤ 8; had a body temperature ≥ 35 °C; and had SSEP records. Good outcome was defined as Cerebral Performance Category scores 1-3 at 1 year. The specificity and sensitivity of different SSEP patterns and amplitudes were calculated.

Results

A total of 457 patients were included in this study. The N20-P
