Head Injury

Background

  • Defined as any traumatic injury to the head other than superficial facial injuries.
  • The commonest cause of death and disability in people age 1-40 in the UK.

Malignant/Accelerated Hypertension

There are several terms commonly used “Accelerated Hypertension”, “Hypertensive Emergency”, “Malignant Hypertension”. They all have a very similar definition (ESC/ESH, NICE, ACEP)

Patient has both:

  1. Blood pressure: Systolic ≥180mmHg OR Diastolic ≥110mmHg (often >220/120mmHg)
  2. End-Organ Damage: Retinal Changes, Encephalopathy, Heart Failure, Acute Kidney Injury, etc.

Mortality has improved in recent years with 5yr survival of 80% if treated. However, untreated average life expectancy is 24 months.

Acute Behavioural Disturbance / Excited Delirium

Most of us will have seen patients like this – agitated, aggressive and often with police or security pinning them down.

  1. High risk of Cardiovascular Collapse/Death – likely due to adrenaline surge, heat exhaustion and injury. It can happen very suddenly.
  2. Keep physical restraint to a minimum – Don’t allow patient to forced face down, it’s the most likely way of killing them.
  3. Sedation – if you’re restraining you will almost certainly need to sedate. IV is best but if access is too risky IM will have to do.
  4. Aggressive management of underlying issues – esp. hyperthermia and acidosis and look out for rhabdomyolysis and DIC

Ingested Magnets

Ingestion of Strong Magnets is a TIME CRITICAL EMERGENCY

(Multiple Magnets OR a single Magnet and Metallic Objects)

Strong magnets  (such as Neodymium)

  • Now common place around the house
  • From; fridge magnets to toys and peicings

Ingested:

  • Intestinal injury can occur within 8-24 hours
  • However, symptoms may take weeks to develop
  • Symptomatic patients are a SURGICAL emergency

Detection:

  • 2 views – to determine number of magnets (if in doubt assume multiple)

Hyponatraemia

Hyponatraema is a common finding, especially within our elderly population. However, its significance is is not a simple numbers game, and needs senior input. Prior to treatment the following need to be considered and balanced.

  1. Symptoms Severity – these are not exclusive to hyponatraemia and may be due to other disease processes (esp. if the low sodium is long-term)
  2. Sodium Level – the sodium concentration doesn’t always correlate to the clinical picture, and is dependant on speed of change, and co-morbidities
  3. Rate of Drop – the faster sodium levels drop the more symptomatic the patient often is (i.e. with long term hyponatraema the patient may be profoundly hyponatraemic but asymptomatic)
  4. Co-morbidities – Increasing sodium too quickly risks osmotic demyelination. How well will the patient cope with treatment?

Emergency treatment (hypertonic saline) is generally indicated in those with Severe/Moderately Severe Symptoms ONLY

Hyperkalaemia

Remember: is it a haemolysed blood sample? (you can do an iSTAT)

Severity

  • Mild: 5.5-5.9mmol/l – No urgent action required (Dietary & Medication modification & GP F/U)
  • Moderate: 6.0-6.4mmol/l – Follow treatment guide (maybe suitable for discharge)
  • Severe: ≥6.5mmol/l OR ECG changes – Follow treatment guide, must admit
