Acute Behavioural Disorder (ABD)

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.

Probably one of the most famous incidents of ABD captured on camera was put down to a rare condition called Folie a Deux. The original documentary clip about Sabina and Urusula Eriksson can be seen here https://www.youtube.com/watch?v=XI2RbVimZK0 and more background, including the murder of a member of the public the following day, found here https://www.cheshire-live.co.uk/news/chester-cheshire-news/bbc-retell-story-twins-who-21560826. One of the most shocking things we thought was the super strength and ability of both twins to virtually bounce back up when seriously injured. 

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.

At the time of writing, the Caribbean superyacht season is in full swing and the Mediterranean season is looming just around the corner in a few months time. It can be a stressful time for any crew, from the most senior to the most junior - and we could all do with a little help to manage stress and our response to it. We’ve written a number of blogs about mental health and things you can do to help manage your own stress and mental health, and when to seek help. We’ve listed them at the end of this blog. But did you know that we can also offer a one day, onboard training session, for the whole crew? Stress Happens! is run in conjunction with the super experienced team at Impact Crew, so you benefit from a business, leadership and team perspective, together with the medical and wellness input. Stress Happens! was developed in response to feedback from superyacht crews and has been running for 4 years. It can be delivered in one day and is suitable for crew at any level. It’s also delivered onboard, making it easy to facilitate the whole crew to attend. The aim is to focus on mental wellbeing and stress, providing tools and techniques to help you to manage your own stress, helping others to manage their stress and knowing where to turn for help if it’s needed.

In this month's blog, as aching hearts aren’t just related to Valentines Day, we’re taking a look at chest pain! Chest pain is a common reason for calls for an ambulance or to shoreside, and frequently it’s not actually due to cardiac (heart) issues. But you will often hear Paramedics tell their patients that they have done the right thing; they would genuinely prefer to get to a patient and find the chest pain is a minor issue, than it being cardiac, and too late! Last year, we wrote this blog about 20 causes of chest pain (plus a bonus one!). Some of the conditions described are acute (sudden onset), some are chronic (long term), some need urgent attention, others not so much. But we should always take chest pain seriously and make sure a full assessment is done at the earliest opportunity to rule out anything life threatening. Typical symptoms of cardiac chest pain and/or a heart attack are:

From Flu jabs to far flung destinations… Vaccinations are a hotly debated topic across the globe, particularly after COVID-19 and the rapid response to the need for a vaccination to help reduce the burden on the health services in different countries. While the majority of healthcare workers and the general population support the ‘prevention is better than cure’ line of thinking, and therefore vaccinations, there are others who are determinedly against vaccinations for any disease, whatever the risk of mortality and death may be. In the UK, the BCG (Bacillus Calmette-Guerin) vaccination used to be given to all children in their teenage years to protect against tuberculosis. The vaccine has been so successful that TB is virtually eradicated now, and the majority of cases are due to migration. Now it’s only given to those deemed at high risk - babies and children at high risk, those travelling to high risk regions and adults coming into the UK from high risk countries. Depending on your country of origin, you should receive a range of vaccinations as a child or young adult. This will most likely include diphtheria, tetanus, polio and whooping cough, hepatitis and HIB (Influenza type B). Then MMR (measles, mumps and rubella), the pneumococcal vaccine (meningitis, pneumonia and sepsis) and HPV (Human Papilloma Virus) with a variety of boosters along the way. At the other end of the scale, the over 65s can receive vaccines for shingles, pneumococcal vaccine and respiratory syncytial virus along with flu and covid vaccines.

Reflection is an essential part of medicine and our regular followers will know that every year, we like to take a look back and assess where we started and how far we’ve come over the last 12 months. So, please join us on our whirlwind recap of 2024 as we get ready for a fabulous 2025… In 2024 we increased the number of STCW training clients to 4 organisations in 6 locations. We delivered STCW training at all levels to over 250 students. We delivered bespoke training to over 75 students onboard Superyachts and cruise ships. We delivered first aid at work or oxygen training to over 40 students, on land and on ships.

Welcome to our December blog, which is all about the recovery position and how to manage an unconscious casualty who is breathing normally. Unconsciousness is a medical emergency as the person is very vulnerable and may not be able to manage their own airway effectively. We also need to think about the cause of unconsciousness. Is it a simple fainting episode due to illness? Is it a massive hemorrhage causing hypovolemic shock? Or is it due to some kind of external factor or injury? This blog looks at how to manage an unconscious casualty. So, if we have a casualty who is unconscious, but who is breathing normally for themselves, and we’re not suspecting a serious injury, the recovery position is the best position to use while monitoring them. The recovery position keeps their airway open and makes sure that vomit or liquid won’t cause them to choke.

All the guest blogs! When we started adding blogs to our website back in early 2021, we did a little feature on each of our instructors of the time. They’re quite a fascinating bunch and the series proved quite popular amongst our followers. In addition to our amazing instructors, we work with some utterly incredible human beings all over the world, and the idea of sharing their stories grew and developed into what eventually became a monthly guest blog. It’s been interesting to find out more about how medical care at sea or in remote locations features in their work, and to discover a few fun facts along the way. This month, we thought that it might be a fun idea to give you a chance to go back into the archives and review all the guest blogs over the last few years! Maybe even let us know which your favourite one is?

We’ve taken a look at the 2023 Casualty Summary Report from the Maritime Authority of the Cayman Islands (MACI) to see what kind of incidents and trends their data shows us, even with relatively small data sets, and how this may be able to transfer to our own risk assessments and actual practice. You can find the report here: Cayman Maritime Report 2023 The first thing we noted was the authors note that the data is split out into incidents. This means that one incident may include a number of events. So a collision and any resulting injury is one incident, but is reported as two events, or more, if more than one person is injured. It made us wonder whether this method of reporting by an authority represents how incidents are reported onboard and whether it should be a consideration? Of course, for any set of statistics presented at the moment, we also have to consider the COVID-19 pandemic and the impact this has on trends including that period. While essential shipping continued, the cruise and superyacht sectors reduced activity and staffing, often to a skeleton crew while anchored somewhere. So this will be reflected in the historic data sets that we analyse from 2019 to 2021 and may not accurately reflect increases and decreases during and since then. In some situations, we may need to look further back for accurate data. We also need to consider whether increases in incidents and events is also down to increased reporting - suggesting an improvement in the awareness of reporting requirements and greater engagement from the industry and individual sectors - this can only be a good development. Since 2020, the type of injury has been recorded in 8 different categories, with hand and foot injuries topping the leaderboard, closely followed by head, body, and back injuries. So if you were looking to run drills, or practise medical skills, these would be the key areas to cover. Only one death was an occupational accident, and is being investigated here: MAIB Investigations (search for case #9229607). It relates to a fall down a ventilation shaft on a bulk carrier in a Greek shipyard. The full report was still pending at the time of writing. Merchant ships are heavily regulated by a number of authorities, and the requirements for personal protective equipment and safe systems of work are enforced and applied to reduce accidents and incidents onboard. This has led to a lower reporting of incidents than in the commercial yacht sector. Could there be room for improvement here in this area? We certainly think so. Many of the hand and foot injuries reported can be career ending or life changing, but are preventable. Follow up has shown that there is a link here with injuries being sustained when inappropriate or no PPE was used. The supply and use of appropriate PPE is mandatory on vessels subject to the MLC and it’s worth remembering that some PPE can be produced in styles and designs compatible with the aesthetics of a yacht if required! On a much wider scale, a lack of transparency and standardisation globally can affect the collection of data and the issue of under reporting. While the MACI figures may be accurate, we need other accurate figures to compare them to, in order to build a bigger picture across the world as we have in aviation. From December 2024, the Maritime Labour Convention (MLC) will be enforcing an amendment so that seafarer deaths will be recorded and reported annually. The MACI and Cayman Islands Shipping Registry produces a number of safety flyers that are publicly available HERE that may be useful. In summary, analysing data can sometimes result in more questions than answers. But even this can lead to interesting and important developments that result in improved safety and reduced incidents and accidents onboard. Key points to take from this report are: Use the correct PPE for the task. Employ approved systems of work and risk assessments for the task. Reporting is key for safety in the future of our industry. Enjoy a night ashore, but don’t over do the cocktails! As always, if you’d like any input on medical training onboard or ashore, or drills that you can run yourselves, please just get in touch.

Welcome to our latest guest blog where we’ve been chatting to James Griffiths, General Manager of Ocean Operations for Scenic Group and finding out more about what happens behind the scenes in order to keep a fleet of luxury expedition ships running. Here’s what James told us… As General Manager of Ocean Operations, I’m responsible for the operations of our fleet which includes four ships in service with around 850 colleagues. I currently live in Mumbles, near Swansea in the UK, but due to the nature of my work I spend a significant amount of time living in Croatia. Prior to this role, I spent many years working at sea and worked up through the ranks to Captain and over the last 15 years, my main focus has been on polar expedition travel. I hold a master mariner certificate of competency in addition to a degree in engineering and a post graduate diploma in law. Part of my job is to work with our medical service provider (Red Square Medical) to ensure that our ships are offering medical services that are appropriate for their deployment, and this can often be to some of the most extreme and remote locations around the world. It’s extremely varied, though during the COVID-19 pandemic, I came ashore when our operations paused for a significant period of time. I was fortunate enough to be given the opportunity to lead the restart of our Ocean Operations, which included setting up everything from a company to manage the ships, to selecting our crewing, medical, helicopter and submarine partners and providers, amongst many other things. Our areas of operation, and the nature of our cruises (expedition), plus having aircraft and submersibles onboard some, do mean additional elements involved in the management of these ships. You could say that this current position is more of a happy coincidence than one that I actually planned for! In some ways this is a great positive - I do think it’s possible to plan a little too much and then be disappointed if things don’t go quite the way you had imagined. But there’s no danger of that here!

Back in February 2022, we brought you one of our very first guest blogs from Simon Lawton, a Paramedic who has swapped out his ambulance for a Superyacht! You can read the original blog here: https://www.redsquaremedical.com/superyacht-paramedic-a-guest-blog-from-simon-lawton Over the last 2+ years, we’ve followed Simon’s career, and some of you may even recognise him as he does put a Red Square Medical instructor hat on from time to time. But, as for all healthcare professionals, Simon has to keep his skills up to date. So, we asked him to tell us a bit more about how he juggles this along with a rota onboard. Here’s what he told us… I’m originally from Stoke-on-Trent in the UK and trained as a HCPC registered Paramedic. I’ve spent almost 5 years working at sea now, with almost continuous employment on three different vessels, after leaving the ambulance service in 2019. My first role was as a Paramedic/Deck hand on Superyachts, and I now work as a Medical Officer on a maritime vessel. Even before I applied to become a Paramedic, I intended to complete my studies to help find employment in a remote or offshore environment. I had always been attracted to the idea of being able to travel the world while earning a salary. Working at sea has meant that I have travelled extensively, earnt a higher salary, and have a better work/rest balance than would be possible in a role on land. Note: At the time of writing, a qualified Paramedic’s starting pay in the UK was £28,407 and Simon’s old rota was 2 days, 2 nights (all 12 hours) and 4 days off with very inflexible annual leave. This year I decided to carry out some continual professional development (CPD) at a hospital in Mexico, to keep my skills up to date. I was interested in travelling to find out more about how healthcare services are provided outside the UK and Europe. The CPD activity in Mexico allowed me to do exactly that, while caring for and treating a wide variety of patients who had either self-presented in the emergency department, or been conveyed to hospital by ambulance.
