Dislocated Shoulder (Teaching Video)

Great review of shoulder reduction, techniques and sedation. 

Learning points:

  • Most techniques will work 80% of the time (Best results tailor the technique to the patient)
  • Kocker’s shouldn’t be used in # greater tuberosity
  • Cunningham technique looks interesting (I’m going to give this a go)
  • Traction is the what causes the most pain. Reduce the traction & Reduce the sedation required

Necrotising Fasciitis

Necrotising fasciitis (NF) is a rare but serious bacterial infection that affects the soft tissue and fascia (Fournier gangrene, is NF affecting the perineum). In many cases NF progresses rapidly and early recognition and treatment is vital to halt progress. The mainstay of treatment is IV antibiotics and aggressive surgical debridement. Any delay increased the amount of tissue loss as well as the mortality. Read more

SAH – NICE 2022

Headache is a common presentation to ED and Subarachnoid Haemorrhage (SAH) is the diagnosis we never want to miss. However, working out who needs a scan can be difficult as 50% of patients presenting with a subarachnoid have no neurological deficit.

  • ‘Thunder Clap’ headache peak of pain within 5min is a RED-FLAG
    • Although, most patients with ‘Thunder Clap’ don’t have SAH, this should not deter emergent investigation
  • Patients may present more subtlety the following should make you consider the diagnosis:
    • neck pain or stiffness (limited or painful neck flexion on examination)
    • photophobia
    • nausea and vomiting
    • new symptoms or signs of altered brain function (such as reduced consciousness, seizure or focal neurological deficit)
  • Always be suspicious if the patient has communication difficulties.

Silver Trauma

The population is ageing and thus our ‘typical’ trauma patient is also changing. In 2017 the TARN report “Major injury in older people” highlighted the following issues:

  • The typical major trauma patient: has changed from a young and male to being an older patient.
  • Older Major Trauma Patients (ISS>15): A fall of <2m is the commonest mechanism of injury
  • Triage/Recognition of ‘Silver Trauma’ is POOR
    • Pre-hospital: Not identified hence taken to TU’s (Here) not MTC’s (Leeds).
    • The ED: Often seen by Junior Staff and endure significant treatment delays.
    • Hospital: Much less likely to be transferred to specialist care.
    • Outcomes: More likely to die, but those who survive have similar levels of disability to younger people.

Hypothermic Arrest [Adult]

True Hypothermic Arrest is thankfully rare in the UK. However, when it does happen it is resource intense and prolonged. The ERC 2021 guidance has introduced a new decision step HOPE score to the algorithm, once the Initial phase of resuscitation has been completed without ROSC.

If the is HOPE score is <0.1  the team may which to consider terminating CPR [Warning: Adults ONLY Children have better survival] Read more

Nitrous Oxide Induced Neurotoxicity

Nitrous Oxide  has been used clinically and recreationally since its discovery in 1772. Since then Nitrous Oxide induced neurotoxicity have been reported, and has been shown to be dose depaendant. With infrequent users unlikely to be at risk of neurotoxicity, while heavier and habitual used at risk of serious neurological conserquences.

With the increase in recreation use of “Whippits” we need to remember to take a detailed recreation drug history when seeing patients presenting to ED with neurological symptoms. As Nitrous Oxide induced neurotoxicity is treatable.

Presentations

Nitrous Oxide induced neurotoxicity can present as either spinal cord demyelination , peripheral neuropathy or a a combination of the two.

  • Demyelination of the dorsal columns of spinal cord 
    • Typically onset is subacute  (i.e. weeks), but acute onset has been reported in the literature
    • Typically symmetrical but can be unilateral
    • Signs
      • Pyramidal weakness – weak upper limb extensors, and lower limb flexors
      • Dorsal Column Sensory loss – Vibration, Proprioception, Fine touch
      • Sensory Ataxia – Incoordination due to loss of proprioception and weakness
    • Level – Most frequently cervical 4-6 levels, but can affect any.
  • Peripheral Neuropathy
    • Typically Symmetrical (but not always)
    • Sensory loss (often painful)
    • Distal Weakness
  • Optic Neuropathy  – has been reported and may present with visual disturbance.

Pathophysiology

Nitrous Oxide usage can render vitamin B12 inactive, which in-turn disrupts myelination, causing the demyelination of nerves.

Differentials

  • Deficiencies: B12, Folate, copper, zinc
  • Inflammatory: Guillian-Barre syndrome, MS, Neurosarcoidosis
  • Infection: HIV, Syphilis
  • Cancer
  • Vascular: Spinal cord ischaemia, vasculitis

Tests

  • Vitamin B12 level (often in normal range)
  • Homocysteine and Methylmalonic Acid Level (not available in ED)
  • MRI – contrast enhanced

Treatment

Start before Tests are back (i.e. on clinical suspicion)

  • IM Vitamine B12 1mg OD
  • PO Folic Acid 5mg OD

Follow-up

  • Discuss admission with Medical team as potential for SDEC management
  • Treat until clinical improvement(King’s Team noted the following)
    • Sometimes treat for 5-7days only
    • Often switch to alternate days IM Bit B12
    • Can teach to self administer
  • Further Testing
    • Homocysteine and Methylmalonic Acid levels – often improve quickly
    • MRI often lags clinical improvement endnote necessary to repeat
  • Majority Improve clinically – but futureabstinence is often challenging
