Neuro Flashcards
Cerebral perfusion pressure
Map-icp=cop
Causes increased icp
Acidosis Hypotonic solutions Hyper extension,flex ion Decreased protein intake Wrist restraints
Cpp norm range
70-95mm hg
Effects basilar skull fracture
Raccoon eyes Battle sign Otorrhea Rhinos rhea Loss of cranial nerve 1(smell)
Brown-sequard syndrome
Ipsilateral(same side) motor loss Contra lateral(opposite side) loss of pain and temp
Central cord syndrome
Upper motor loss
Varying sensory loss
Bacterial meningitis
Staph auras Very elevated protein Low glucose Purulent Leukocytes
Viral meningitis
Enterovirus, herpes virus Elevated protein Normal glucose Clear Lymphocytes
Signs of meningitis
Head aches
Nuchal rigidity
Brudzinkis sign
Kernigs sign
Doll eyes
Oculocephalic reflex
Cushings triad
Increase systolic bp
Widening pulse pressure
Decreased hr and rr
Normal ventricular fluid pressure
0-10
Blindness in half of both visual fields
Homonymous hemianopia
Pinpoint pupils from
Legion/infarct in pons
Pons
Sympathetic in elevation
Midbrain ns
Parasympathetic
Causes pancreatitis
Obstruction pancreatic ducts
Alcoholism
Drug toxicity
Trauma
Pancreatitis symptoms
Hypocalcemia Low insulin haank Left side atelectasis and pleural effussions Bilateral rales Cullen's and ray turners sign Ards Elevated amylase levels
In pancreatitis don’t give
Morphine. Give Demerol
Lbo
Large distention
Sbo
Small distention
Diarrhea
Vomiting
Parasympathetic
Makes pupil pin point
From midbrain
Sympathetic
Causes pupil dilation
Pons
Uncal herniation
Lateral shift
Uncal herniation —- pupil on —– side
Dilates. Effected side
Supratentorial herniation changes
Loc and dilates both pupils
Gcs measures
Eyes open motor verbal
Cushings triad
Widening pulse pressure
Increase sbp
Decreases hr and rr
Cullen’s sign
Edema and bruising on umbilicus
Grey turners sign
Bruising of flanks
Brudzinskis sign
Hips and knees flex when neck is flexed
Kermis sign
Cannot straighten leg when hip flexed 90 degrees
Rind
Reversable iscemic neurological defict
Long Tia
Ci
Cerebral infarct
2 brain arteries
Basilar vertebral artery
Carotid artery
Brainstem 3 parts
Midbrain
Pons
Medulla
Ocular nerve
3rd cranial nerve
Uncal herniation causes
Changes in pupils
Supratentorial herniation causes
Changes in level of consciousness
Then dilated pupils
Then death
Cushings triad occurs during
Supratentorial herniation
Resp pattern seen I’m upper brainstem(midbrain) region
Hyperventilation
Reap in pons infarct
Apneustic breathing
Normal ventricular fluid pressure is
0-10 mmHg
Pin point pupils indicate
Infarct or lesion in pons
Pancreatitis electrolyte abnormality
Hypocalcemia
