Pre-Hospital Event Health: Rapid Medical Intervention – Saves Lives.

Case Study

Colbrow Medics provides event health and medical care services including multidisciplinary Medical Assistance Teams (MATs) to high risk events where there is a possibility for patients at the event to require critical care medical service, or medical services beyond the level of first aid, such that these patients can be assessed, treated and either rapidly moved to a hospital environment for continued care, or allowed to continue enjoying the event, delaying or preventing a hospital presentation.

Practically, this means that people at our medical tents are able to get the kind of expert critical care they’d typically receive in a hospital ER. No waiting for an ambulance or the time to get to hospital; a high level of critical care is available on the spot.

Summary

A Colbrow Medics Medical Assistance Team was deployed to a single day music event with a duration of about 10 hours. The team consisted of a Senior Emergency Medicine Doctor, as well as 5
Registered Nurses who specialise in Emergency and Intensive Care nursing. They were supported at the event by a number of Paramedics and first aid level staff. An 8 bed medical centre was deployed, which included a 2 bed Resuscitation unit. 7 hours into the event, a male patron in his late 20s was carried into the resuscitation area by a number of security staff. He was confused and agitated and unable to walk on his own.

O/E

It was obvious to the experienced team members that this patient was critically unwell. He was rapidly connected to full non-invasive monitoring including ECG, non-invasive blood pressure and
pulse oximetry monitoring. He was found to be tachycardic at 130bpm, hypertensive at 160/95 and hyper-pyrexial at 40.6°C. He had normal oxygen saturations of 100% on room air and of note, his skin was pink and dry.

The patient was quickly assessed as having a life threatening problem and the resuscitation crew was rapidly assembled.

Rx

First aiders and primary responders will be familiar with the DRSABCD approach to patients. However, most do not consider the patient themselves as a danger. In this case, the patient was a
manual handling risk to the security staff, a big risk of falling off the stretcher due to his agitation, and a risk to the treating team due to flailing arms and an overwhelming desire to keep moving.
Under the careful guidance of the Colbrow Medics Doctor, and initial sedative medication (Midazolam) was administered intramuscularly. This allowed the patient to settle on the stretcher,
such that he no longer needed to be physically restrained. At this point, he could have 2 intravenous lines placed (Tip: The cephalic vein is often a large calibre, superficial vessel that traverses over the anterior aspect of biceps brachii. Particularly in young, athletic males, this provides an excellent cannulation site as it is straight, away from joints, readily palpable and visible and large in size.) and a further dose of sedative (Midazolam) administered intravenously.

During the initial phase of the team’s treatment, it became apparent that the patient had a condition known as hereditary anhidrosis – an inability to sweat. He was also known to have used some
substances at the event that likely had a stimulant (sympathomimetic) clinical effect. Such substances include caffeine, amphetamine and its derivatives including MDMA or ecstasy, cocaine
and ketamine. This combination had led to a critical rise in core body temperature, which has the potential to cause seizures, melt body tissues and cause severe electrolyte and kidney disorders.
Our patient needed to be cooled rapidly to get his temperature below 38°C. The first step in achieving this was rapid infusion of cooled intravenous fluids and placement of icepacks in areas where large blood vessels are near to the skin – the armpits and groin. Cool intravenous fluids are a standard piece of equipment for Colbrow Medical Assessment Teams at events such as this one. The second step in cooling this patient, was to minimise muscle energy consumption and heat production. For this, our patient needed deep sedation and muscle paralysis. In paralysing a patient,
the respiratory muscles are also paralysed, meaning the patient won’t be able to breathe for themselves. Thus the patient will need an endotracheal tube to be placed and will need to be
connected to a ventilator to breathe for them. Additionally, the subconscious pain reflexes triggered by panic of being awake and paralysed or having laryngoscopy performed to place the endotracheal tube, mean the patient will need high dose pain killers and sedative medications. The Colbrow Doctor used a general anaesthetic agent (propofol) as well as analgesic agents (fentanyl
and morphine) and sedative (midazolam) to place the patient in an induced coma. A paralysing agent called rocuronium was used to relax the patient’s muscles. They were then able to place the
endotracheal tube and breathe for the patient without complication. Simultaneously to this occurring, an Intensive Care Paramedic team had been arranged through the close working relationship of Colbrow Medics and Ambulance Victoria, and the receiving hospital was notified by the Colbrow Medics Doctor of the patient’s impending arrival. The patient’s vital signs had normalised by the time of their departure from the event, most importantly their temperature had fallen to 37.6°C, below the threshold of 38°C.

Outcome

The patient was woken and extubated about 4 hours after their arrival in hospital. Whilst there was already some evidence of muscle (including heart muscle) damage from the hyper-pyrexia, there was no evidence of brain or kidney damage. From the time of arrival to the Medical Assessment Team to the time of departure from the event was less than 1 hour, during which time the patient had been taken from a life threatening situation, to a critical but stable condition with good prospects for recovery. The patient stayed in hospital for about 36 hours prior to being discharged and never required Intensive Care Unit admission, thanks to the pre-hospital care he received at the event.

He made a full recovery.
