Q

What happens if the nerves that control ventilation become paralysed?

A

Hypoventilation

20
Q

What nerves innervate the diaphragm?

A

C3, 4 and 5

21
Q

What nerves innervation the intercostal muscles?

A

The thoracic

22
Q

What causes Neurogenic Shock and what does it result in?

A

Disruption of the sympathetic chain.

Results in vasodilation, hypotension, warm peripheries, bradycardia and poor thermoregulation.

23
Q

What will a patient need if they cannot breath for themselves.

A

External ventilation.

24
Q

What do sympathetic nerves supply?

A

Fight and flight.

25
Q

What do the parasympathetic nerves supply?

A

Rest and digest.

26
Q

What are the signs and symptoms of spinal injury?

A

Conscious-
Spinal pain
Weakness or paralysis
Numbness, tingling, altered sensation.

Any conscious level-
   Loss of bladder control
   Priapism.
   Difficulty breathing.
   Exaggerated reflexes.
27
Q

What is priaprism?

A

A persistent erection without stimulation.

28
Q

What do you do in CUF with spinal casualty?

A

Prioritise getting to safety.

29
Q

What do you do in a semi permissive environment with a spinal casualty.

A

Bear it in mind but follow CABCDE.
Immobilise in blunt/blast injuries.

Remember there is no benefit to immobilisation with penetrating trauma.

30
Q

What can you do when it is safe to do so?

A 
Immobilise
Safely move to neural allignment
Maintain manual stabilisation.
Apply semi-ridged collar.
Log roll to scoop.
Secure with blocks and tape.
Maintain airway. (Jaw thrust)
Consider ventilation
Treat hypotension with fluids titrated to radial pulse.
Monitor temperature, prevent hypothermia.
31
Q

Who can clear a c-spine injury?

A

Doctors, Nurses and other healthcare professionals.

32
Q

What requirements must be met to clear c-spine.

A 
GCS 15
No intoxication
No distracting injury
No focal neurological deficit
No posterior mid line tenderness
33
Q

What are the most common injury seen in conflict?

A

Limb injuries often penetrating.

34
Q

What limb injuries are common?

A

Traumatic amputations and limb-threatening injuries.

35
Q

What is concerning about limb injuries?

A

Contaminated wounds and ensuing infection often lead to complications.
Limb injuries can be life threatening.

36
Q

What are traumatic amputations often caused by?

A

Blast effect

Mines and IEDs

37
Q

What are major vascular injuries often caused by?

A

Pentrating wounds.

Blunt trauma and fractures/dislocations.

38
Q

What can fractures cause?

A

Major blood loss.

39
Q

What happens with crush injuries.

A

Tissue ischaemia and possible cell death.
Myoglobin release, possibly leading to renal damage, acidosis, oedema, systemic inflammatory response, hyperkalaemia leading to arrhythmia.

40
Q

How should you manage a crush injury?

A

Reduce time and give fluids to keep profusion to the kidneys.
Be careful fluids do not have potassium in them.

41
Q

What is compartment syndrome?

A

A condition where pressure inside a fascial area becomes greater than capillary pressure preventing profusion.

42
Q

What are the common compartments associated with compartment syndrome?

A

Forearm and lower leg.

43
Q

What can raise pressure in compartments?

A

Oedema or blood from fractures or trauma.

44
Q

How would you recognise compartment syndrome?

A

Limb is very painful, pain increases on passive stretch, swollen compartments, tense and tender, sensation may be altered. May be pale. Might have paralysis. Pulses may or may not be present.

45
Q

How do you manage a limb injury

A 
CUF:CAT
Semi-permissive:CABCDE
Look and feel, check peripheral pulses.
Triage limb threatening wounds as T1
Clean and dress.
Splint fractures and compartment syndrome.
Analgesia and antibiotics.
