Chapter 5, 6, 7, 9 Flashcards
Autonomic Storming
AKA dystonia
failure of sympathetic or parasympathetic components of the autonomic nervous system to regulate body functions
-characterized by disruptions in heart and respiratory rates, BP, temperature, perspiration, muscle overactivity, posturing, dystonia, rigidity, and spasticity
Deep vein thrombosis
blood clot in and deep venous part of the circulatory system
common in TBI
Pulmonary Embolism
blockage of a main artery in the lung frequently caused by a blood clot that has traveled from elsewhere in the body (often a DVT)
Urinary Tract Infection
- occur early and late post-BI
- may be detected through cognitive or behavior changes
is bladder or bowel incontinence behavioral or intentional
no, typically not. There is great shame and embarrassment in not being able to control these functions
Treatments for incontinence
foley catheter suprapubic catheter timed-voiding schedule anti-cholinergic drugs bowel routine
aspiration
material/bolus passing level of vocal folds into airway
The Congress of Neurological Surgeons states that in the acute phase following a head injury, a person will require at least ___% more calories than he or she needed prior to the injury
40%
BI present in ___% of SCI cases
60%
Effect on BI co-occurring with SCI on LOS and motor outcomes
People with paraplegia and co-occurring severe TBI had worse motor outcomes and longer acute rehab LOS than individuals with only paraplegia and no TBI
Complete SCI
no motor or sensory function below level of injury
incomplete SCI
functioning of sensory and possibly motor below the level of injury
decubitus ulcers
pressure injury/sores from prolonged pressure on any area due to positioning and increased spasticity or tone
important principles to prevent decubitus ulcers
Use bracing (immobilization, external fixation, orthotics)and proper wheelchair/bed positioning
Stage I Pressure Injury
red and warm to the touch
may itch or burn
timely identification may help reverse and minimalize further damage
Stage IV Pressure Injury
- most severe
- may lead to potentially serious infection, which may be life threatening
- result in large open areas of tissue destruction down to and including muscles, bones, tendons, and joints
How to prevent pressure sores
- keep skin clean and dry
- change position every 2 hours
- pressure-relieving devices: specialty mattress, specialty cushions, tilt in space w/c
MRSA (stands for, cause, treatment)
Methicillin-Resistant Staphylocuccus Aureus
- typically a product of poor hygiene, including poor hand washing by care providers and repeated use of soiled clothing
- requires antibiotics to treat
3 Categories of seizures after a TBI
(classified by time of appearance after initial impact)
- Immediate post-traumatic convulsions (IPTC)
- within seconds of impact - Early post-traumatic seizure (EPTS)
- within first week - Late post-traumatic seizures (LPTS)
- >1 week after BI
Immediate post-traumatic convulsions (IPTC)
involve loss of consciousness and involuntary movement within seconds of impact
Early post-traumatic seizures (EPTS)
- occur up to 7 days after initial impact
- result of primary direct effects of the trauma
- approx 50% occur within 24 hrs of impact
- strong risk factor of late post traumatic seizures
Late Post-Traumatic seizures (LPTS)
- greater than 1 week after initial head trauma
- generally within first 18-24 months after BI
- also known as post-traumatic epilepsy
- presence of seizure disorder associated with increased mortality
- individuals with post-traumatic epilepsy die at a younger age than those that do not. Worse with advanced age at time of injury and presence of SDH
tonic posturing
back arching, eyes roll back in head
clonic/myoclonic jerks
muscle spasms causing a jerking in limbs less than 2-3 min in duration
Postictal period
short period of time following a seizure where there is an altered state of consciousness
decerebration
loss of cerebral brain function
hippocampal atrophy
shrinkage of the hippocampus
status epilepticus
more than 30 min of continuous seizure activity or two or more sequential seizures without full recovery of consciousness
Causes of pain after BI
orthopedic pain muscular pain headache spasticity/contracture HO myofascial pain neuropathic pain
nociceptive pain
pain related to peripheral nerve fibers
neuropathic pain
associated wtih primary lesion dysfunction of nervous system
pain management strategies
NSAIDs OTC pain meds (acetaminophen) topical agents antispasticity meds opoids nerve blocks steroids ice heat ROM stretching ultrasound therapy TENS
post-traumatic headache (PTH)
- headache that commences within 14 days of LOC
- may spontaneously resolve within 6 months or symptoms may persist and become chronic
Percentage of people who get PTH after mTBI vs moderate-severe TBI
95% after mTBI
22% after moderate-severe
primary headache
headache with no specific cause
secondary headache
headache that may have identifiable cause that can be determined
chronic headache
occurs at least 15 days per month for at least 3 months
primary nocioceptive afferent nerves involved with post-traumatic headache
CN V (Trigeminal) CN IX (Glossopharyngeal) CN X (Vagus) Greater Occipital Nerve (from C2 root) Lesser Occipital Nerve (from C3 root)
