We’ve recently been working on an issue of our newsletter ‘Worse Things Happen at Sea’ and a couple of blogs to follow it. The topic is drug use onboard and the follow ups take a closer look at the most common drugs you might encounter, either at work or just out and about.
One of the potential side effects of drug use is acute behavioural disorder, though you might be more familiar with the previous name of excited delirium. We thought it would be a great blog subject in itself. So, here’s our take on ABD…
Acute behavioural disorder (or disturbance) is a potentially life-threatening syndrome of delirium, dysregulated physiological responses and aggressive behaviour. It is most commonly caused by illicit drug use but can also be caused by a range of medical conditions and psychiatric disturbance. So this sounds serious, right? A bit more of a problem than getting a bit giggly and silly.
So, first things first, what are the signs and symptoms of ABD and just how would you recognise it:
- Rapid breathing
- Increased pulse rate
- Confused thinking and speech
- Altered mental status
- Bizarre behaviour
- Extreme agitation
- Disorientation
- Hallucinations
- Aggression
- Violence
- Shouting
- Constant or near constant physical activity
- Appears not to get tired
- Hyperthermia - too hot
- Unexpected physical strength
- Paranoia
To give you an example, one of our trainers gave us a summary of a job they attended. The call came in from the Police and the patient had drawn attention to himself by running across a road in front of the police car and diving (like he was diving into a swimming pool) onto the pavement.
It took 5 police officers to detain the patient who was shouting, sweating profusely and very agitated. When the ambulance arrived, the patient was brought on board shouting ‘The apocalypse is coming. Tell the Government… we need the Russians!’. His agitation and constant movement was so extreme that assessment was almost impossible while he was in that state.
He was later put into a police van for transport to the custody suite (the medics there are able to monitor and treat) where he proceeded to tear chunks of bullet proof material apart with his bare hands, making the vehicle useless and off the road. This was all put down to ADB following some kind of substance abuse.
Delerium isn’t always quite so dramatic though. Anyone who has experienced an elderly relative with a UTI (water infection), or someone with a very high or very low temperature/blood glucose may well have noted levels of confusion and hallucinations. There are many medical conditions that can cause similar symptoms, but they are normally seen without the extreme behavioural traits described above.
One of the key risks of ABD is the vulnerability of the patient, and the fact that they may make poor decisions leading to harm and/or death.
There’s also a high risk of a sudden cardiovascular collapse due to adrenaline surge, heat exhaustion and injury. While restraining the patient to keep themselves and everyone else safe may seem like a good idea, physical restraint, especially face down or for a prolonged period can be catastrophic.
The best way forward if ABD is suspected is to try to minimise the chance of injury. If you can’t control the patient, try to move anything dangerous or that could become a weapon from the area. Communication can be difficult as the patient may not be responding normally, can appear extremely confused and probably won’t be rational.
Seek medical help at the earliest opportunity and try to keep the patient cool (environment, drinking fluids if they will) if they appear to be overheating. Of course this may be easier said than done.
Remember to go back to your ABCs! Keep yourself safe first, and remember that patients suffering from ABD can flip from calm to violent at any time without warning. Get some medical help, and be prepared to resuscitate if needed.
