Wang et al reported a risk score for predicting hydrocephalus in an adult after intracranial hemorrhage. The authors are from multiple institutions in China.
Hydrocephalus may occur in about 9% of adults with cerebral hemorrhage.
Patient selection: adult with intracranial hemorrhage
Parameters:
(1) Glasgow coma scale (GCS), from 3 to 15
(2) fever time in days
(3) CSF total protein multiplied by time, with CSF total protein in mg/L and time in days, with time presumably referring to time of onset
(4) age in years
