2
Q
What are the management principles for TBI patients (3)

3
Q

4
Q
What should be used to sedate patients with TBI and a high GCS + low suspicion of raised ICP?
A
Midazolam
5
Q
What should be used to sedate severely agitated patients needing a PHEA with TBI?
Why? (2)
A
Ketamine
- Some evidence it reduces ICP in patients whose ventilation is being controlled

6
Q
What 3 things should we ensure when performing PHEA in TBI?

- Avoid PEEP if able
- Aim ETC02 of 4.5
9
Q
Why must we pay particular attention to BP in TBI?
A
Patient can lose their ability to auto-regulate cerebral blood flow. Hypotension can therefore lead to reduced cerebral oxygenation even if normal ICP
10
Q

SBP >120 and MAP >90
11
Q

To ensure that patients with facial injuries have appropriate assessment and
management on scene, especially where airway compromise or haemorrhage
present a threat to life.
1. Describe the particular considerations for pre-hospital anaesthesia in maxillofacial
injury.
2. Describe the methods used to attempt to control excessive haemorrhage from
maxillofacial injury.
120
What is the background of the maxfax SOP?
1. Due to the rich
blood supply to the head and neck, it is possible to exsanguinate from facial injuries
2. Aim to recreate a stable column for the facial skeleton, which will allow some restoration of anatomical alignment and
hence minimise ongoing haemorrhage.
3. Usually associated with an obstructed airway
(actual or impending)
4. For the epistat balloons to provide tamponade rest of the 'column' most first be in place
121
What can causes epistats to be ineffective/worsen maxfax bleeding?
For the epistat balloons to provide tamponade
in the nasal space it is important the hard palate is braced against the lower jaw
[which is supported by a cervical collar] with dental blocks / McKesson props.
Failure to utilise all of these adjuncts will result in a mobile maxilla being pushed off the base
of the skull and increasing the space for bleeding.
122

1. All procedures should be performed using sterile technique.
2. Formal assessment and confirmation of landmarks must take place prior to any surgical incision being made.

127
What does the blunt chest injury SOP state about paediatric patients?
Given chest wall pliability can show no/limited external signs injury but have significant internal injuries
128
