Infectious Processes Flashcards
guillan barre s/s
acute flaccid paralysis
hyperasthesia - sensitive to touch (even a sheet)
nerves effected in hands and feet first (stock and glove)
guillan barre cause
unknown - immune response
guillan barre
peripheral nervous disorder - destruction of myelin sheath and schwann cells (peripheral nerves) - can regenerate
poly neuropathy - affecting multiple nerves
guillan barre can follow these problems
trauma surgery flu immunizations gastroenteritis
guillan barre is a ascending or decending presentation
ascending paralysis, goes from feet up to arms - symtpoms show 1-3 weeks after event
guillan barre is an ascending or decending recovery
decending - feet are the last to come back may take weeks or months for recovery
dx of guillan barre
hx, clinical signs
csf
complications of guillan barre
respiratory muscle paralysis
infection - aspiration - immobility complications - dvt
what happens in lymes disease
tick attaches to body - neurotoxic stuff - remove the tick
how do you remove a tick
don’t squeeze it or burn it off with a lighter
use tweezer be sure to get all of it out
can lymes disease be transferred person to person
no
s/s of lymes disease
bullseye
when does tick paralysis go away
with removal of the tick
dx of lymes disease
studies are not reliable until later disease process
commonly based on hx
what is meningitis
an acute inflammation of CNS (meningeal tissue)
cause of bacterial meningitis
organisms enter CNS (streptococcus pneumonia) spread to brain through (increased) CSF leading to swelling of brain tissue and increased ICP
meningitis can be
septic or aseptic
classic triad of symptoms r/t bacterial meningitis
fever, stiff neck or nuchal rigidity, chg in LOC
s/s of meningococcal
rash that resembles bruising that doesn’t fade when pressed
what happens in meningococcal
circulation to extremeties is diminshed (shocky, hypotensive) necrotic tissue leading to gangrene need for amputation
predictors for meningitis
+kernigs and brudzinski sign (indicative of bacterial meningitis - irritation of the spinal cord
which cranial nerve, if effected, usually doesn’t return
cranial nerve VIII-permanent hearing loss
dx of meningitis
LP - papiledema due to ICP - blood cultures - START ANTIBIOTICS before results are in - low sugar
if pt has papiledema would you do LP
no, could cause herniation
