Abstract:
OBJECTIVETo explore the value of lower-limb short latency somatosensory evoked potentials (SLSEP) in predicting early death in patients with massive cerebral infarction.
METHODSForty-eight patients of massive cerebral infarction were admitted in the Neurological Intensive Care Unit (NICU) between March 2008 and March 2009, and Glasgow-Pittsburgh coma scale (GPCS) and SLSEP were recorded and graded within 24 h after admission. The patients were divided into survival and death groups (including brain death) according to their short-term prognosis. The correlations of SLSEP and GPCS to the mortality were assessed.
RESULTSA significant correlation was found between SLSEP and the mortality in patients with massive cerebral infarction (r=0.484, P<0.001). The positive predictive value of the SLSEP grade 3 to death was 100%, and the patients with malignant middle cerebral artery infarction (mMCAI) appeared to have a 100% mortality.
CONCLUSIONSLSEP grade 3 can be a highly specificity in predicting early death in patients with massive cerebral infarction, and it is also of value in determining the timing of surgical intervention of mMCAI.
