Neuro Procedures - Told Flashcards
(35 cards)
quincke
spinal fluid analysis
first EEG
hans berger
CSF pressure
25-30cm
should not exceed 30cm
level of spinal tap
below L2 - end of cord
L4-5 easiest
spinal tap needle
short bevel only
blunt - to feel pop
precede spinal tap
CT scan
-unless meningitis is suspected
low spinal fluid pressure
below 7cm
hypoproduction
distal to occlusion
spinal fluid leak
spinal cord tumor
get terrible HA
patch of spinal cord
blood patch
appearance of spinal fluid
should be clear
xanthochromic
old blood pigment
-remote bleeding
cloudy CSF
if greater than 200WBC or 400RBC
infection/inflammation
neutrophil in CSF
infection bacterial
lymphocytes in CSF
viral fungal infection
monocyte in CSF
macros
chronic condition
gram stain
positive in bacterial infection of CSF
CSF glucose
lag one hour behind blood glucose
never lower than 80% blood glucose
protein in CSF
less than 45 mg/dL
rise in 1 - for every 1000RBC present
oligoclonal bands on CSF
MS
epidural
into potential space
no fluid or blood
space outside spinal canal accesible to nerve roots
meds outside spinal canal
cost of EEG
expensive
theta waves - seizure activity
negative EEG
never negates seizure
-majority of seizure pt will have negative EEGs
EEG brain mapping
localize for seizure surgery
Xray in neuro diagnosis
for fractures
walk the line
looking at cervical trauma
see C1-7 and T1
