Term
cheyne stokes and tbi
Definition

 

see diaphoresis in these patients, arrhythmic pattern with long periods of apnea

 

Cheyne stokes an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea. The pattern repeats, with each cycle usually taking 30 seconds to 2 minutes.[1] It is an oscillation of ventilation between apnea and hyperpnea with a crescendo-diminuendo pattern, and is associated with changing serum partial pressures of oxygen and carbon dioxide.[2]usually indicates bleeding

 

Neurogenic hyperventilation- hemorrhaging on brainstem affecting lower brainstem and eventually breathing will stop

Brain stem= HR, BP, respiration control

 

get 3 on GCS in motor section due to flexion of muscles as a neuro muscular response to trauma

Term
decebrate posturing
Definition

 

posturing is also called decerebrate response, decerebrate rigidity, or extensor posturing. It describes the involuntary extension of the upper extremities in response to external stimuli. In decerebrate posturing, the head is arched back, the arms are extended by the sides, and the legs are extended.[6] A hallmark of decerebrate posturing is extended elbows.[13] The arms and legs are extended and rotated internally.[14] The patient is rigid, with the teeth clenched.[14] The signs can be on just one side of the body or on both sides, and it may be just in the arms and may be intermittent.[14]

 

A person displaying decerebrate posturing in response to pain gets a score of two in the motor section of the Glasgow Coma Scale (for adults) and the Pediatric Glasgow Coma Scale (for infants), due to his or her muscles extending because of the neuro-muscular response to the trauma.

Definition

 

These fractures tend to occur from the tend to travers the paranasal sinuses of the frontal bone or middle ear located in the temporal bone producing hemmhorage from nose, ear, pharynx, and subconjunctiva areas.

Sudden depression of reflex activity

 

Spinal cord levels below injury are without sensation paralyzed and flaccid and the reflexes are absent.

Need to be monitoring for neurogenic issues if someone has an injury to c-spine


Caused by loss of autonomic nervous system fucntion below level of lesion
Vital organs affected
Decreases in
BP. Cardiac output. Venous pooling in the extremities.
Peripheral vasodilation. Lack of perspiration in paralyzed areas due to black of sympathetic activity.
Sudden high temps due to sympathetic dysegulation
In cervical and spinal cord injuries, innervation to accessory muscles causes decreased vital capacity, retention of secretions, respiratory failure and decrease O2 levels pulmonary edema

Term

american spinal injury association impairment scale-don't have to know all details

 

Definition

 

A: complete. No sensory or motor function is preserved in the sacral segments S4-S5.
B: sensory incomplete. Sensory but not motor function is preserved below the neurological level and includes the sacral segments S4-S5 (light touch, pin prick at S4-S5 or deep anal pressure), AND no motor function is preserved more than three levels below the motor level on either side of the body.
C:  motor incomplete. Motor function is preserved below the neurological level and more than half of key muscle functions below the single neurological level of injury (NLI) have a muscle grade less than 3.
D: motor incomplete. Motor function is preserved below the neurological level and at least half of key muscle functions below the NLI have a muscle grade of 3 or greater.
E: normal. If sensation and motor function as tested with the ISNCSCI are graded as normal in all segments, and the patient had prior deficits, then the AIS grade is E. Someone without an initial SCI does not receive an AIS grade.

 

 

 

Term
cauda equina
Definition

 

Bundle of nerve roots emanating from L1-2 area

 

Looks like horses tail

 

The most common cause is lumbar intervertebral disk herniation. Other causes include traumatic injury, abscess, spinal anesthesia, tumor ankylosing spondylitis, inferior vena cava thrombosis, lymphoma, and sarcoidosis. The nerve roots of the caudaequina are susceptible to injury and increased permeability, which may then lead to edema formation even with the slightest injury.

Numbness in perineal area- loss of sexual sensation, urinary retention, can be very painful and disabling

Anything that compresses caudaequina nerve roots can cause it

CES is rare, occurs equally in men and women, and isn't age specific. Occurring traumatically or atraumatically, CES may result from any lesion that compresses the cauda equina nerve roots, which can occur from inflammation, direct compression, ischemia, or venous congestion. CES has no definite criteria for diagnosis. Diagnosis includes your patient's clinical history, physical exam, and radiologic testing. as

 

 

Term
cauda equina S and S
Definition

 

The patient usually presents with low back pain that's different than common lumbar strain, unilateral or bilateral lower extremity motor or sensory abnormality, b/b complaints.

 

Bladder sxs: incontinence or retention, bowel incontinence, perineal anesthesia, pain in the legs or radiation to the legs, reflex abnormalities (loss or diminished), pain localized to the low back, and poor sphincter tone.

 

To prevent and avoid lifelong disability, a careful examination and history taking is crucialfor referral to spine specialist
if caught early and diag correctly, long term projects can be prevented
