Q

Define permissive hypotension

A

When a clinician allows a pts systolic blood pressure to fall lower than normal without intervention (fluids).
The blood pressure will avoid exsanguination (the action or process of losing blood) but is high enough to maintain perfusion.

Q

What is the aim of permissive hypotension?

A

Maintain an adequete vasoconsriction, organ perfusion and prevent undesireed coagulopathy during initial fluid resuscitation. And to avoid disruption of an unstable clot by higher pressures and worsening bleeding

Q

When shouldnt permissive hypotension be considered?

A

Controversey with blunt trauma as it can lead to poor outcomes as a result of tissue hypofunction
Bleeding and TBI - Blunt trauma dont give fluids unless bp is less than 90
Penetrating trauma and trauma of the trunk - dont give fluids less than 60

Q

Define secondary brain injury

A

This injury can occur from minutes to days following initial injury.
Hypotension - SBP < 90
SATS < 90 Percent
The skull is a rigid container that cannot accomodate bleeding or swelling

Q

When do you begin ventilations?

A

Signs of ineffective breathing or poor perfusion.
<10 resps adult and <30 for children

23
Q

What are some indications for pre hospital EA (anaesthesia)?

A

Airway compromise
Failure of airway protection
Failure of ventilation or oxygenation
GCS<8
To facilitate safe transport (danger to themselves or the crew)

24
Q

What are the contraindications for PHEA?

A

Known anaphylaxis
obvious physical deformity making intubation unsuccessful
croup or epoglottis

25
What are some early signs of rising ICP?
Vomiting headache dizziness amnesia visual disturbances altered LOC Seizures
26
What are some late signs of rising ICP?
Cushings triad - bradycardia, irregular respirations, and a widened pulse pressure Pupil changes coma posturing
27
What is important with spinal cord injuries?
Effective managemt from the time the injury occurs.
28
What are some specific symptoms to spinal cord injuries?
C spine or spinal pain loss of sesnsory function in the limbs loss of motor function in the limbs sensation of burning in the trunk or the limbs
29
What is neurogenic shock?
Occurs when a spinal cord injury interrupts the sympathetic pathway.
30
in regards to spinal cord injuries what is neurogenic hypotension?
Hypotension in the absense of tachycardia
31
What are some signs and symptoms of neurogenic shock?
Bradycardia hypotension results from both vasodilation and slowed heart vasodilation below the injury level reflects interruption to sympathetic supply leading to vasodilation, hypotension, warm peripheries and priapism
32
What causes spinal shock?
- Result of direct trauma or shock to the spinal cord - Loss of usual neurological activity at or below the injury
33
What drug can be used if the patient is bradycardic?
Atropine
34
What is the function of the skin?
Barrier against UV raise, bugs and infections Helps regualte temperature helps with sensation of pain and touch Absorbs lipid soluable substances
35
What are the layers of the skin?
Epidermis - first line of defence Dermis - Highly elastic layer of connective tissue containing collagen (provides strength) and elastin (provides elasticity). Has specialsed skin structure (nerve endings, sweat glands and hair follicles) Subcutaneous - Mainly adipose tissue and serves as an insulator and an energy reserve for the body
36
Why is the eye more susceptible to injuries?
The thickness of the layers being so small
37
What layer of skin is a superficial burn?
Epidermis
38
What does superficial burns involve?
Local pain Blistering likely after 24 hours Healing time 3-5 days
39
What layer of the skin is a superficial partial thickness burn?
Partial dermis involvement
40
What does a superficial partial thickness burn involve?
Blisters (thin walled) developing within minutes Nerve endings exposed due to the blisters 3-4 weeks healing time
41
What layer of the skin involves a deep partial thickness burn?
Destruction of the dermis
42
What happens in a deep partial thickness burn?
Burns appear white and waxy likely to require a skin graft long term negative effects
43
What layer of the skin is affected in a full thickness burn?
Subcutaneous or deeper involvement
44
What will happen with a full thickness burn?
Wound will appear dry and leathery skin will lose elasticity As oedema forms distal circulation may be compromised if burns become circumferential The site of the burn will be painless as nerve endings are destroyed
45
What app can be used to estimate the amount of burns?
Mersey burns app
46
With burns what is the approach with cooling?
Running cool water for 20 minutes ASAP- effective up to 3 hours after burn Burns can also cause irreversible cooagulation to the skin
47
What is essential management in a heat burn?
Cooling is essential Contact time with heat source may not be as important as the source itself Find out what the burning material was (carbon monoxide etc)
48
What is essential management of a chemical burn?
PPE ESSENTIAL Cooling may be required for more than 20 minutes first irrigation with normal saline if power present - brush off before irrigation
49
What is essential management for an electrical burns?
Scene saftey May not be visible surface burn look for entry and exit burn ECG ESSENTIAL
50
What is essential management for radiation burns?
Sunburn - if skin is intact management is oral hydration and pain relief Acute ionising radiation burn from accident or industrial source - require specialist help
51
What is the management for a friction burn?
Remove debris carefully frostbite is skin damage and not as a burn should be managed as a thermal burn
52
What are the clinical features of carbon monoxide poisoning?
Headache flu like symptoms dizziness precipitate angina seizures gastrointestinal disturbance symptoms will worsen when in affected area and will improve when outside
53
What is the main treatment for carbon monoxide poisoning?
Oxygen use COMA to assess for carbon monoxide poisoning
54
What mechanism can cause a chest trauma
Blunt or penetrating
