Danger - the engineer has self extricated and is able to move to the medical room. We will assume that the digit has been rescued and is with the patient.
Response - he is responding normally, though in a lot of pain. This gives us time as we know he is breathing and can maintain his own airway.
Shout for help - of course at sea, you’d have to shout pretty loud and you are the help! So what other communications do you need to activate at this stage?
Catastrophic bleeds - in this case there will be some bleeding, but direct pressure should control it well and it’s unlikely to be life threatening. The patient may even be able to apply the pressure himself. Depending on the type and location of the wound, the pressure could be on top of the wound, or around the finger.
C-spine consideration
- We still need to consider whether the mechanism of injury may suggest a c-spine injury, or if it’s just an isolated traumatic injury.
Airway
- We’re pretty confident at this point that the airway is open and self maintained. The patient is talking to you freely.
Breathing
- again, the patient is talking, so we know he is breathing. For this kind of injury we wouldn’t normally suspect a clinical breathing issue, but pain and anxiety could result in an anxiety attack.
We might expect the breathing rate to be a little high straight after the injury, due to pain and stress. But we would expect this to settle within a short time.
The normal rule for trauma is to give 15 litres of Oxygen to help the body heal at a cellular level, regardless of what the Pulse Oximeter reading states. But what if your limited resources don’t include Oxygen? Or if you do have Oxygen, what would you do if you know you have to manage the patient for 5 days? Would you give Oxygen initially and consult with Telemedicine to decide when to reduce or withdraw it?
Circulation
- We need to monitor whether the initial bleeding has stopped. This is also where we would think about storing the amputated digit in a damp dressing, in a plastic bag, on ice. While we may think there’s no point if help is 5 days away, we also need to consider whether things could change and a rescue be actioned before then, in a suitable time frame for reattachment.
We can clean and dress the wound, making sure we can access it again to monitor for infection over the 5 days.
We might expect the heart rate to be a little high straight after the injury, due to pain and stress. But we would expect this to settle within a short time.
In our previous case studies, we also added on a couple of other letters to our DRsCABC assessment.
Disability
- we need to monitor the level of consciousness over the prolonged period that the casualty is with us. We can check blood sugars and pupils - if trained to and if the equipment is available.
Exposure - Once we’ve dealt with the obvious injury, we do need to expose and check for any other injuries. Any injury can be termed a ‘distracting injury’ and means that we can never assume the patient is sure there is nothing else going on.
The other key part of exposure is the temperature. Even in warm climates, we need to keep all patients, and particularly trauma patients, warm. We can monitor the temperature if a thermometer is available and make sure the patient is kept warm - even if they are moving around. A rectal temperature is most accurate, but a tympanic (ear) thermometer works well in most environments.
A high temperature can also be the early warning sign of an infection developing.
So, we now have an initial plan. But what happens next?
