Exam 3 - Cindy's Flashcards
(48 cards)
Concussion
Mild brief loss of neurological function
DAI
Prolonged coma caused by coup/countercoup injury
Epidural hematoma (EDH)
ARTERIAL bleeding, bleeding between dura and skull; middle meningeal artery rupture, Brief loss of consciousness, followed, by a lucid period and then deep coma
Craniotomy Care
Post-Op: neuro checks, monitor for IICP, check airway, pain, nutritional status and any CSF leaks
Complications of SAH (subarachnoid hemorrhage)
Vasospasms
Rebleeds
Hydrocephalus
C-1 thru C-4 Cervical spine injury
Assess airway, lose diaphragm use, ventilator dependent
Major complications of spinal cord injuries
DVT / PE
Autonomic dysreflexia
Exaggerated autonomic response t visceral stimulation occurring with injuries above T6.
MEDICAL EMERGENCY
TX/Interventions for Autonomic dysreflexia
Elevate HOB, check for bowel impaction, bladder distenstion, and kinks in foley, evaluate skin for pressure areas. Medicate for HTN using HYPERSTAT, Resperpine or Atropine
Plasmaphresis
Infection, hypovolemia, clotting abnormalities, hypokalemia, hypocalcemia, hypotension, myasthenic and cholinergic crisis
Contusion
Bruising of the Brain
Subdural hematoma (SDH)
VENOUS bleeding, between dura and arachnoid layers; see progressive neuro changes over 2-4 weeks
SIADH
Complication post head injury, see coma, may have lung crackles decreased urine output
Subarachnoid hemorrhage (SAH)
Bleeding into subarachnoid space between pia and achachnoid layers, usually from rupture of Berry aneurysms.
Nimotop (nimodipine)
Prevents vasospasms, give for 21 days
Spinal shock
May last weeks to months, see flaccid paralysis below the level of lesion, lose temp control, see hypotension
Use of steroids in spinal cord injury
Treats secondary injuries, decreases swelling/inflammation of cord
S/S of Autonomic Dysreflexia
Severe HTN HA Bradycardia Flushing of the face/neck pupil dilation
Myasthenia Gravis
Affects neuromuscular transmission of voluntary muscles. See excessive weakness and fatigue of voluntary muscles. Any age, more common in women ages 14-35 and men over 40. Tensilon test will confirm diagnosis
Guillian-Barre syndrome
Rapidly ASCENDING peripheral and cranial nerve dysfunction, leading to paralysis. Respiratory arrest is most common cause of death. check vital capacity and ABGs every shift in assessing respiratory function.
Monroe-Kellie Doctrine
An increase in blood, CSF, or brain tissue is accompanied by a reciprocal change in the volume in one of the others
How to estimate cerebral perfusion pressure. What is normal CPP?
CPP = MAP - ICP
Normal CPP is 60-100 mmHg
Factors that increase ICP
Valsalva, coughing, sneezing, body positions, neck flexion
Cushing’s Triad
Increased systolic pressure with decreased diastolic pressure (widened pulse pressure) and bradycardia
