Road traffic collisions are a leading cause of death and injury. Following a road traffic collision many patients will remain trapped in their vehicle. Extrication is the process by which injured or potentially injured people are removed from their vehicle by the rescue services. Rescue service training focuses on the absolute movement minimisation of potentially injured patients’ spine and has developed extrication techniques with the focus of movement minimisation. Unfortunately these techniques take significant amounts of time (30 minutes plus); this delays access to potentially lifesaving treatments for injuries. In this Road Safety Trust funded project, the EXIT team across nine published academic studies reconsider extrication, provide evidence of harm, demonstrate that current techniques do not minimise movement as intended and provide a framework of principles for evidence-based extrication: Operational and clinical team members should work together to develop a bespoke patient centred extrication plan with the primary focus of minimising entrapment time Independent of actual or suspected injuries patients should be handled gently. A focus on absolute movement minimisation is not justified When clinicians are not available, FRSs should where necessary assess patients, deliver clinical care and make and enact extrication plans (including self-extrication) 1 Self-extrication or minimally assisted extrication should be the standard ‘first line’ extrication for all patients who do not have contraindications, which are: -An inability to understand or follow instructions, -Injuries or baseline function that prevents standing on at least one leg, (specific injuries include: unstable pelvic fracture, impalement, bilateral leg fracture) All patients with evidence of injury should be considered time-dependent and their entrapment time should be minimised Incidents where a patient may require disentanglement are complex and associated with a high morbidity and mortality. A senior FRS and clinical response should attend such instances 2 Clinical care during entrapment: -Can be delivered by FRS or clinical services 1 -Should be limited to necessary critical interventions to expedite safe extrication 3 -Rescuers should be aware that clinical observations may prolong entrapment time and as such should be kept to the minimum -FRS and clinical personnel should be aware of the physical and observable signs of patient deterioration and if identified should make this known to the responsible clinician Immobilisation: -Longboards are an extrication device and should not be used beyond the extrication phase -Kedrick Extrication Devices prolong extrication time and their use should be minimised -Pelvic slings should not be applied to patients until they have been extricated -Cervical collars should only be used following assessment and should be loosened or removed following extrication Patient focused extrication: -Build a connection with patients, explain actions, and use their name -Where appropriate, reassure patients as to the safety of their co-occupants and others involved in the incident (including animals) -Provide an ‘extrication buddy’ -Allow communication with family members or other close contacts -Rescue teams should not publish extrication related imagery to social media or other outlets -Minimise the ability of the public to view the accident, take photographs or record videos. Provide education to this effect On initial call to Emergency Services -Attempt to clarify entrapment status -Attempt to identify patients who require disentanglement (and dispatch an appropriate priority senior 2 response) -A standard multi-agency MVC trauma message should be developed to ensure the correct resources are deployed Multi-professional datasets should be developed with patient and public engagement and should include entrapment status, entrapment time, injuries, extrication approach, clinical care Agreed nomenclature for categories of patient Not injured, Minor injuries (evidence of energy transfer but no evidence of time-dependent injury), Major injury (currently stable but should be assumed to be time-dependent), Time critical injured (Time critical due to injury; use fastest route of extrication) m Time critical hazard (e.g. secondary to fire or other hazard) These principles have been adopted by national level stakeholders in the UK are being incorporated into national clinical and operational guidance which will reduce entrapment time and may demonstrate morbidity and mortality reductions.

This was a joint podcast with our friends & colleagues at WEMCast – to hear more from them, have a look at their podcast back catalogue , and there’s more information on the World Extreme Medicine website . OLYMPUS DIGITAL CAMERA OLYMPUS DIGITAL CAMERA OLYMPUS DIGITAL CAMERA OLYMPUS DIGITAL CAMERA Mosquito born disease Malaria risk areas. From: https://www.iamat.org/risks/malaria Malaria is transmitted through the bite of an infected female Anopheles mosquito. It is widely distributed throughout tropical regions of the world, within the majority of cases reported in Africa. If you would like to read more about malaria; its signs & symptoms, variants, at-risk countries and treatment, have a look at the Travel Health Pro website . Dengue risk areas . From https://travelhealthpro.org.uk/factsheet/13/dengue Dengue is a viral disease transmitted by mosquitos. Symptoms include high fever, muscle and joint pains, headache, nausea, vomiting and rash. It is generally a self limiting illness with improvement in symptoms and recovery occurring three to four days after the onset of the rash, although rarely can lead to dengue haemorrhagic fever. Again, the Travel Health pro website has some excellent information on this. Zica virus is spread by day-biting mosquitos. In addition a few cases of transmission by sexual contact have been reported. It is found in parts of Africa, Asia, the Pacific Islands, Central and South America and the Caribbean. The majority of people infected with Zika virus have no symptoms. For those with symptoms, it is usually a mild and short-lived viral type illness, with conjunctivitis and muscle/join pains. However, Zika virus is a cause of Congenital Zika Syndrome (microcephaly and other congenital anomalies) and neurological complications such as Guillain-Barré syndrome. Read more here .

Some facts Drowning is important: 1,000 people drown every day, 2 every 3 minutes, 41 per hour. It is the world’s 3rd leading cause of accidental death: 3.6 million people over 10 years. Disease of youth 64% < 30 years old 43% < 15 years old 25% < 5 years old Male: female ratio 2:1 In 40%, alcohol is on board 4 stages of Immersion associated with particular risk in drowning Initial Responses/Sudden Death (first 3-5 min) Skin cooling Short-Term Responses (5-30 min) Superficial Nerve and Muscle Cooling Long-Term Responses (30 min +) Cooling of deep tissues Post-immersion (during rescue) Collapse of arterial pressure Continued cooling Fresh versus salt water drowning Lethal aspiration of salt water 22ml/kg (approx 1.5 litre), fresh water 44ml/kg Be aware that drowning can take up to 4 hours – observe and watch for 6! Prognostication Better outcomes: Rescued and BLS commenced < 5-10 min Children Those who have not aspirated Water temperature < 10 o C, core body temperature 33-35 o C Neurologically intact on arrival at hospital Minimum blood pH > 7.1, blood glucose < 11.2mmol/L ROSC on scene Spontaneous ventilation in ED Worse prognosis Risk of death or severe neurological impairment after hospital discharge is reported to be nearly 100% when the duration of submersion exceeds 25 min Following 30 mins resuscitation, if no signs of life, resuscitation is futile -> stop It is important to remember that casualties who have entered water sometimes have access to a “bubble” of air – particularly if they had entered the water following a boating incident or were in a car at the point they entered the water. In these circumstances it is impossible to judge the point at which submersion has occurred. What about cold water??? This is a regular point of discussion and concern. Water temperature is a key determinant: icy versus not. In the UK sea water is very unlikely to be icy or cold enough – however, small areas of water may well be, particularly in the winter months.

Risk stratification This is the Emergency Medicine Specialty guide we discussed in the podcast, which includes use of the NEWS and 40 step test (edit: since recording the podcast yesterday (!) we’ve been made aware of the Sit to Stand test ). Here is a review of both if you’d like to read more. PPE As at May 1st, the advice from PHE is ‘ There is currently sustained transmission of COVID-19 throughout the UK as defined by the four nations Public Health experts, therefore there is an increased likelihood of any patient having coronavirus infection. Therefore, whilst in this phase all patient contacts require level 2 PPE in accordance with Table 4 ‘: T4_poster_Recommended_PPE_additional_considerations_of_COVID-19 Level 2: disposable gloves disposable apron fluid repellent surgical mask eye protection (if risk of splashing) Level 3: disposable gloves fluid repellent coveralls/long sleeved apron/gown FFP3* or powered respirator hood eye protection *Where an FFP3 mask with a non-shrouded valve is worn, it should be accompanied by a full-face visor. If a visor is not available, then a risk assessment should be carried out regarding the risk of splash to the valve. If a large splash (as opposed to droplets) does occur, then the FFP3 mask should be replaced immediately. There are a number of PHE PPE videos available, this is the one describing donning and doffing Level 2. From PHE Guidance for ambulance trusts: Where AGPs such as intubation are performed, PPE guidance set out for AGPs (section 8.1) should be followed (disposable fluid repellent coveralls may be used in place of long-sleeved disposable gowns). For any direct patient care of patient known to meet the case definition for a possible case, plastic apron, FRSMs, eye protection and gloves should be used. Where it is impractical to ascertain case status of individual patients prior to care, use of PPE including aprons, gloves, FRSM and eye protection should be subject to risk assessment according to local context. PPE is not required for ambulance drivers of a vehicle with a bulkhead and those otherwise able to maintain social distancing of 2 metres. If the vehicle does not have a bulkhead then use of a FRSM is indicated for the driver (additional PPE would be as for other staff if providing direct care). For the coverall-type Level 3 PPE most commonly being used by ambulance clinicians, have a look at these two guidelines on donning and doffing . Aerosol generating procedures Reference available here . Aerosols are produced when an air current moves across the surface of a film of liquid; the greater the force of the air the smaller the particles that are produced. Aerosol generating procedures (AGPs) are defined as any medical and patient care procedure that results in the production of airborne particles (aerosols). AGPs can produce airborne particles <5 micrometres (μm) in size which can remain suspended in the air, travel over a distance and may cause infection if they are inhaled. Therefore AGPs create the potential for airborne transmission of infections that may otherwise only be transmissible by the droplet route. The most recent assessment by WHO (2014) states that there is only consistent evidence that there is an increased risk of transmission for the following procedures: tracheal intubation, tracheotomy procedure, non-invasive ventilation, and manual ventilation before intubation as AGPs. This evaluation is based on a systematic review by Tran et al. whose review included 10 studies (5 case-control; 5 cohort), all of which investigated transmission of SARS from patients to healthcare workers in intensive care or other healthcare settings during the 2002-2003 SARS outbreaks. Cardiac arrest From PHE: First person attending scene In order to minimise any delay attending a time critical cardiac arrest, it is acceptable for the first person to enter the scene wearing level 2 PPE (fluid repellent surgical mask, apron, gloves and eye protection). Where trained and equipped to use level 3 PPE, this may be used where it will not cause a delay commence resuscitation where this is indicated by local clinical guidance. If resuscitation is not commenced, or is terminated before the arrival of other resources, provide an early sitrep to reduce the number of responders who need to enter the scene do not place your face near the patient to assess breathing where available, place a surgical mask or oxygen mask on the patients face commence chest compressions, attach the defibrillator and defibrillate if indicated. None of these tasks are considered aerosol generating procedures (AGPs) do not progress to airway management or ventilation if not already available on-scene, request back up from a level 3 PPE trained response Subsequent attendance at scene of responder(s) trained and equipped to use level 3 PPE don level 3 PPE enter scene and determine whether the resuscitation should be continued according to local clinical guidance. if resuscitation is to be continued, take over patient management from any responder wearing level 2 PPE all responders wearing level 2 PPE are to leave the scene (more than 2m away from the patient) prior to the commencement of any airway management, ventilation or other AGPs. Responders may later re-enter if trained and equipped to wear level 3 PPE level 3 PPE responders to continue the resuscitation, including airway management and ventilation Anyone who is not trained or does not have access to level 3 PPE must then withdraw from the scene.
