Rabies [notifiable disease]

Recent Incident: Bat contact was not recognized (effectively touching a bat without gloves means treatment is recommended)

Rabies is an acute viral encephalomyelitis caused by members of the lyssavirus genus. The UK has been declared “Rabies-Free”. However, it is known that even in  “Rabies-Free” counties the bat population posse a risk.

In the UK the only bat to carry rabies is the Daubenton’s Bat [Picture on the Left] and this is not a common bat in the UK. The UK and Ireland are Classified as “low-risk” for bat exposure. Despite our “low-risk” status in 2002 a man died from rabies caught in the UK from bat exposure.

Although rabies is rare it is fatal so we must treat appropriately, Public Health England – Green book details this.

Risk Assessment

To establish patients risk and thus treatment you need to establish the Exposure Category and Country Risk [Link to Country Risk]

Exposure Category

Combined Country/Animal & Exposure Risk

Treatment

Obviously patients with wounds will need appropriate wound care and cleaning, specifics for rabies are below.

If in ANY doubt, or you feel you need advice about treatment contact: On-Call Microbiologist (who will contact PHE or Virology advice)

 

You will likely need to liaise with the duty pharmacist to obtain vaccine or HRIG – which may need to be sent from a different hospital. [it is probably worth trying to obtain the 1st weeks treatment if possible, to avoid treatment delays]

Measles

Suspected/Confirmed patients should be ISOLATED & wear PPE 

Treating Staff – (should not be; non-immunised, pregnant or immunocompromised)

  • single-use, disposable gloves
  • single-use, disposable apron (or gown if extensive splashing or spraying, or performing an aerosol generating procedure (AGP))
  • FFP3 – respiratory protective equipment (RPE)
  • eye/face protection (goggles or visor)

Patient

  • Surgical face mask

Background

  • Measles is highly infectious – (4 day prior to and after rash appears) suspected patients should be isolated within the ED
  • Measles Immunisation – 1 dose 90% effective, 2 doses 95% effective
  • Measles is a notifiable disease

COVID-19 (Paediatric multisystem inflammatory syndrome)

AKA: Paediatric Inflammatory Multi-system Syndrome – Temporally associated with SARS-CoV 2 

Although COVID-19 seems a benign disease in almost all children there are increasing evidence (however rare) of a “Paediatric multisystem inflammatory syndrome”. This is a RARE and newly emerging condition and there are many questions still e.g. It is currently unclear if it is directly related to the COVID-19 pandemic.

COVID-19 (40 Step Desaturation Test)

NHS England has introduced the use of a “40 step desaturation test” into discharge planning from the ED. You will have heard Covid -19 patients complaining of increasing SOB on exercise, and it’s important that we test this prior to discharge.

Method:

  • Is this appropriate? – Could the patient walk 40 steps before they were ill?
  • Patient remains in cubical – with mask on
  • Attach Sats probe – ensure good trace
  • Walk on spot 40 steps 
  • Monitor SaO2

 

 

COVID-19 (Awake Self-Proning)

There is increasing evidence that Awake Self-Proning of our Covid-19 patients can improve oxygenation. Proning the patient can has several effects which can dramatically improve their SaO2

  • Improves Ventilation to back of the lung (the back of the lung contains more alveoli than the anterior lung)
  • Improves Perfusion – as blood supply to the back of the lung is always better than the front
  • Improves Clearance of secretions
  • Be patient can take 15-20min

Contraindications (all seem obvious)

Absolute contraindications:

  • Respiratory distress (RR ≥ 35, PaCO2 ≥ 6.5, accessory muscle use) 
  • Immediate need for intubation 
  • Haemodynamic instability (SBP < 90mmHg) or arrhythmia 
  • Agitation or altered mental status 
  • Unstable spine/thoracic injury/recent abdominal surgery 

Relative Contraindications: 

  • Facial injury 
  • Neurological issues (e.g. frequent seizures) 
  • Morbid obesity 
  • Pregnancy (2/3rd trimesters) 
  • Pressure sores / ulcers
