Rabies [notifiable disease]

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

Important: Rabies Vaccine is in short supply and we must do a UKHSA risk assessment.  Call RIgS 09:30-17:00 7 days, OR complete Form

 

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]

IN HOURS 08:30AM-5PM PLEASE CALL PHARMACY TO INFORM THEM TO EXPECT A DELIVERY OF IMMUNOGLOBULIN SO THIS CAN BE SEGREGATED FOR THE CORRECT PATIENT. PLEASE ASK TO SPEAK TO THE RESPONSIBLE PHARMACIST                      CRH (4218/4279) HRI (2422/7123)

ASPEN Collar fitting

Fitting ASPEN collars is import – for both the comfort and function of the collar. The DENS study has been looking at the effectiveness on collars in peg fractures. Preliminary results suggest limited benefit, which made be due to the fact the many patients remove the collar early as not comfortable.

Cervical Spine Clearance in the trauma patient

Although in ED we cannot prevent the primary injury, our objective is to recognise and prevent secondary injury. Through the use of the agreed standards

Standards:

  1. Spinal protection must remain in place if an injury is suspected/identified, or until it is excluded via an established protocol.
    • Unless a senior clinician has clearly documented a decision, immobilisation not in the patients best interest.
  2. Assessment of the whole spine should be performed and documented where injury is suspected.
  3. If abnormal clinical signs are found, complete neurological examination must be performed and documented.
  4. If spinal injury identified OR abnormal neurological signs consistent with spinal cord injury are found, immediate discussion with and referral to a centre capable of emergency spinal surgery must occur.
  5. Significant spinal injury is excluded following either:
    • Normal clinical examination in an awake and orientated patient with no clinically significant distracting injury OR illness is present; the patient can concentrate on and reliably report neck findings. (in line with Canadian C-Spine rules)
    • Completion of spinal imaging protocols (standard 6).
  6. Imaging protocols:
    • Thoracic and lumbar spine scans should be obtained according to major trauma protocols.If a cervical spine injury is suspected, thin slice CT scanning from occiput to T4, including sagittal and coronal reconstructions should be performed without delay.If whole-body CT (WBCT) for trauma is necessary, this should include the cervical spine if injury is suspected.
    • An initial report of spine clearance imaging should be available before the patient leaves the Emergency Department.
OptionScenarioAction
1This investigation demonstrates an injury that may affect spinal stability. (see Notes)Continue spinal protection and seek advice from an appropriate clinical team. 
2This scan is of good quality and there are no comorbidities confounding its interpretation. No features of instability, such as fracture, haematoma or joint disruption are seen.Patients with NO acute neurological symptoms/signs on examination or mobilisation.Spinal protection may be removed.
Patient who HAS acute neurological symptoms/signs on examination or mobilisation.Continue spinal protection and seek advice from an appropriate clinical team. 
Unconscious OR unable to Co-Operate with examination (see Notes)Spinal protection can be removed with caution providingConsultant Radiology report & No evidence of acute neurological deficitIt must be recognised there is a <1% chance of unrecognised injury. ANY evidence of neurological deterioration should be re-immobilised pending MRI
3Whilst there are no obvious features of spinal instability, the CT scan is either not of good quality and/or there are comorbidities confounding its interpretation.Continue spinal protection until MRI is performed and report available.

Magnetic Resonance Imaging is necessary when the following are present:

  • Suspected cord injury
  • Ambiguous CT scans, as per option 3 of standard 6
  • Inability to assess patient, as per option 2 standard 6 
  • Ankylosed spines with negative or indeterminate CT appearances for fracture
  • Contraindications to ionising radiation, for example in pregnancy

    Notes:

    • Option 1 Standard 6: Certain Spinal injuries may be combatable with removal of protection on agreement of the base speciality consultant:
      • Facet joint fractures of the thoracic and lumbar spine
      • Spinous process fractures
      • Wedge compression fracture with loss of vertebral body height of less than 25%
      • Type 1 odontoid fracture
      • End-plate fracture
      • Transverse process fracture
      • Trabecular bone injury
      • Osteophyte fracture, excluding corner or teardrop fractures
      • Isolated avulsion fractures
    • Option 2 Standard 6: Management of Unconscious or patients unable to fully co-operate with clinical exanimation is recognised as significant challenge. With advances in CT the number of significant injuries missed is very low <1%. However, there are significant risks associated with prolonged immobilisation, especially for frail patients who are more likely to fall into this group. 

    This pragmatic approach is in line with BOA-Standards, however, it must be recognised there is a chance of deterioration. If ANY evidence of neurological deficit the patient should be re-immobilised and reassessed for further imaging. 

    Complications of prolonged use of Immobilisation:

    • Impaired venous drainage and increased intracranial pressure
    • Difficult laryngoscopy and intubation
    • Increased risk of aspiration and ventilator-associated pneumonia
    • Difficult central venous cannula insertion
    • Increased risk of central venous cannula associated blood stream infections
    • Increased risk of pulmonary thromboembolism
    • Pressure necrosis leading to ulceration
    • Inability to provide good oral care
    • Failed enteral nutrition, gastrostasis and reflux
    • Restricted physiotherapy

    Medical Emergencies in Eating Disorders

    Eating disorders* are relatively common and unfortunately patients who “look well” can have a significant mortality risk. MEED.org.uk have national risk tools to recognise those that would benefit from admission, which fit with our local mental health teams, and agreed by both acute medicine and paediatrics

    (*anorexia nervosa, bulimia nervosa, binge eating or avoidant restrictive food intake disorder)

    Risk Assessment

    Hip Dislocation – Flowchart

    Dislocation of a Native Hip

    • Uncommon – High-Energy injury
    • All patients presenting with a suspected native hip dislocation following trauma (including falls from standing) must have a primary survey done to assess for other injuries.
    • Early Senior input (if not trauma team) and Resus
    • Neurovascular status of the affected limb must be assessed and documented. 

    Dislocation of Prosthetic Hip

    • Relatively common and frequently low energy
    • All patients should be assessed with low threshold to treat as trauma
      • Remember the biggest cause of ISS >15 Major Trauma in UK is older patients falling from standing height
    • Neurovascular status of the affected limb must be assessed and documented. 
    • If there is neurovascular compromise then move to Resus and inform ED senior
