Q

Linear skull fracture

A

Account for 80% of skull fractures; also referred to as non-displaced skull fractures. Occur commonly in the temporl-parietal region; Usually no scalp signs, needs CT to notice

Uninjured brain + NO scalp lacs = non-life threatening
Linear skull fracture + scalp lacs = high risk of infection and bleeding inside of the brain

Q

Axial loading injuries

A

Injuries in which load is applied along the vertical or longitudinal axis of the spine, which results in load being transmitted along the entire length of the vertebral coloms (e.x. falling from a height and landing on the feet in an upright position)

Q

Cerebral edema

A

Swelling of the brain; may not develop until several hours following the initial injury
Aggravated by low oxygen levels - ensure viable airway, ventilations and high-flow O2

Q

Closed head injury

Study These Flashcards
A

Injury in which the brain has been injured but the skin has not been broken so there is no obvious bleeding

25
Coup-Contrecoup injury
Dual impacting of the brain into the skull; coup injury occurs at the point of impact, countercoup injury occurs on the opposite site side of the impact as the brain rebounds
26
Eyes forward position
A head position in which the patient's eyes are looking straight ahead and the head and torso are aligned
27
Four person log roll
The recommended procedure for moving a patient with a suspected spinal injury from the ground to a long backboard or other spinal immobilization device
28
Intervertebral disk
The cushion that lies between two vertebrae
29
Meninges
Three distinct layers of tissue that surround and protect the brain and spinal cord within the skill and spinal canal Dura mater - tough fiberuos, forms a sac to contain the CNS Arachnoid & Pia mater - contain blood vessels that nourish the brain and spinal cord When all layers are penetrated, CSF may leak
30
Primary (direct) injury
Injury to the brain and its associated structures that is a direct result of impact to the head
31
Racoon eyes
Bruising under the eyes that may indicate a skull fracture; typically a late sign
32
Secondary (Indirect) injury
The after effects of the primary injury; includes abnormal processes such as cerebral edema, increased intracranial pressure, cerebral ischemia and hypoxia, and infection; onset is often delayed following the primary injury
33
Subarachnoid hemmorage
Bleeding into the subarachnoid space where CSF circulates
34
Traumatic Brain Injury
TBI; a traumatic insult to the brain capable of producing physical, intellectual, emotional, social and vocational changes
35
Peripheral Nervous System
31 pairs of spinal nerves (sensory impulses, motor impulses) 12 pairs of cranial nerves (transmit information directly to/from the brain, 5 senses)
36
Most common MOI for head injuries
Motor vehicle crashes, >2/3 of people involved experience head injuries Followed by assaults, older adult falls, sports-related incidents
37
Seizures and convulsions
It is not uncommon for patients with head injuries to have a convulsion or seizure as a result of excessive excitability of the brain caused bu the direct injury of the accumulation of fluid within the brain
38
Hyperventilation
Controversial because it can increase the severity of head injuries and therefore should be avoided except in cases where signs of brainstem herniation have been identified
39
Glasgow Coma Scale
``` Eye Opening 4 - Spontaneous 3 - In response to speech 2 - In response to pain 1 - none ``` ``` Best Verbal Response 5 - Oriented conversation 4 - Confused conversation 3 - Inappropriate words 2 - Incomprehensible sounds 1 - none ``` ``` Best Motor Response 6 - Obeys commands 5 - Localizes pain 4 - Withdraws to pain 3 - Abnormal flexion 2 - Abnormal extension 1 - none ```
40
Injuries to C5-6
Quadripeligia
41
Injuries to L1
Paraplegia
42
Cheyne-Stroke respirations
fast and then slow with periods of apnea
43
Ataxic (biot) respirations
irregular rate and volume with periods of apnea
44
Cushing Triad
Also referred to as herniation syndrome where intracranial pressure is so great that it forces the brainstem and midbrain through the foramen magnum; can be fatal Increased blood pressure (hypertension), decreased heart rate (bradycardia) and irregular respirations Signs of a traumatic brain injury
45
When to leave a helmet on?
1) there are no impending airway/breathing problems 2) it does not interfere with assessment and treatment of airway/breathing problems 3) you can properly immobilize the spine
46
When to remove a helmet?
Removing a helmet should always be a two person job! 1) it is a full-face helmet 2) it makes assessing or managing the airway difficult and removal of a face guard to improve airway access is not possible 3) it prevents you from properly immobilizing the spine 4) it allows excessive head movement
47
``` Which of the following is NOT a part of the central nervous system? The Brain The spina cord CSF Cranial Nerves ```
Cranial Nerves
48
The nervous system is divided into the central nervous system and the
Peripheral nervous system
49
The brain is divided into the cerebrum, the cerebellum and the _____
Brain stem
50
Injury to the head and neck may indicate injury to the _____
C-spine
51
Which of the following is NOT a function of CSF? Acts as a shock absorber Bathes the brain and spinal cord Buffers the brain and spinal cord from injury Provides continuous oxygen to the brain
Provides continuous oxygen to the brain
52
The most prominent and most easily palpable spinous process at the base of the neck
C7
53
Neck rigidity, bloody CSF and headache are associated with what kind of bleeding in the brain?
Subarachnoid hemorrhage
54
The first step in securing a patient to a backboard is
to provide manual stabilization of the C-spine
55
The most reliable sign of a head injury
Decreased LOC
56
Hyperventilation should be used with caution in head injury patients and only be attempted when ____ is available
Capnography
57
How many EMTs needed to immobilize a standing patient?
3
58
A vacuum mattress molds to the specific contours of the patient's body and ____, ____, _____
Reduced pressure point tenderness, provides better comfort and provides thermal insulation
