CDE Detailed Report

Meningitis/ventriculitis depends on
- A positive cerebrospinal fluid culture
In addition to one of the following:
-- Fever > 38°C
-- Increased white blood cells, elevated protein or decreased glucose in cerebrospinal fluid
-- Positive Gram stain of cerebrospinal fluid

Day after SAH on which the neurological complication 'Meningitis/ventriculitis' first occurred (day of ictus = day 0). This date can precede the date on which the CSF culture yielded a micro-organism.

Day after SAH on which the neurological complication 'Clinical deterioration due to delayed cerebral ischemia' first occurred (day of ictus = day 0)

Hydrocephalus is defined by:
- Hydrocephalus on CT or MRI, defined as a bicaudate index above the 95th percentile based on age: 0.16 for patients 30 years or younger, 0.18 for patients 31-50 years, 0.19 for patients 51-60 years, 0.21 for patients 61-80 years, and 0.25 for patients 81-100 years.
- And one of the following:
-- CSF drainage by lumbar puncture, lumbar drainage, ventricular drainage
-- A decrease in the level of consciousness of at least 2 points lasting for = 1 hour

Diagnosed when both of the following are present: (1) complete or near-complete effacement of the hemispheric sulci and basal cisterns, and (2) bilateral and extensive disruption of the hemispheric gray-white matter junction at the level of the centrum semiovale, either due to blurring or diffuse peripheral "finger-like" extension of the normal demarcation between gray and white matter.

Clinical deterioration consistent with brain shifting, manifesting as progressive reduction in level of consciousness associated with motor posturing and either pupillary abnormalities, gaze abnormalities, or autonomic instability (HR, BP, RR)
