Early Cortical Median Nerve Somatosensory Evoked Potentials

How reliable is the predictive value of SEP (somatosensory evoked potentials) patterns in severe brain damage with special regard to the bilateral loss of cortical responses?

“…Our findings of a highly significant correlation of initial SEP scores with later outcome (measured by the GOS) correspond well with the results of earlier studies [1][2][3][4][5][6][7][8][9], demonstrating the predictive value of median nerve SEP recording in the early phase of posttraumatic coma for both a favorable and an unfavorable prognosis, even during treatment with sedatives and muscle relaxants. As the severity of evoked potential abnormalities (SEP score according to Anderson et al [1], CNC, am- plitude ratio N20/N13) increased in our study, favorable outcomes decreased.…”

Accuracy of clinical signs, SEP, and EEG in predicting outcome of hypoxic coma

“…Our search yielded 25 original articles [7][8][9][10][11][13][14][15][16][17][18][19][20][21][22][23][24][25][30][31][32][33][34][35][36] that met the inclusion criteria (table 1). Twenty-one were written in English, 2 were in German, and 2 were in French.…”

The Utility of Median Somatosensory Evoked Potentials in Anoxic-Ischemic Coma

“…Numerous studies confirm that the absence of short-latency CEP is associated with a uniformly unfavorable prognosis 71, 3,5,7,10,11,13,14,21,22,36,46,47,52,53,54,66,677. Most studies did not distinguish between minor and severe deficits among patients who recovered awareness.…”
