    • Explain decision and options as clearly and concisely as possible (be flexible)
    • Make every effort to help the person understand (language line, writing, etc.)
    • Are there others who might help them understand? (nursing, medical, family, freinds)

Concealed Illicit Drugs

Background

Those suspected of concealing illicit drugs often present near ports and borders however they can present to any ED or be brought in by the police.

Body Packers – Swallow large quantities of well packaged drugs to smuggle them into countries or institutions.  These are often well manufactured with a low risk of rupture but the potential for serious toxicity if rupture occurs.

Body Stuffers – Swallow small quantities of poorly packaged illicit substances often at the point of arrest to conceal them. These have a much high risk of package rupture but involve smaller quantities of substances.

 

Investigations

Authorisation for an intimate search or radiological investigation must come from an inspector or higher with written consent from the patient.

Intimate searches must be carried out by a police surgeon but require immediately available resuscitation facilities therefore may be conducted in the ED. ED physicians should not handle the drugs at any time.

AXR or low dose CT scanning can be used to detect concealed packages in Body Packers.

 

General Management

Try to obtain a history of what and how much has been concealed

Look for toxidromes suggestive of package leak –

  • Cocaine: Tachycardia, hypertension, agitation, diaphoresis, dilated pupils, hyperpyrexia, seizures, chest pain, arrhythmias and paranoia.
  • Heroin: pinpoint pupils, respiratory depression, decreased mental state, decreased bowel sounds
  • Amphetamines : – Nausea, Vomiting, Dilated Pupils, Tachycardia, Hypertensions, Sweating, Convulsions and the development of non-cardiogenic pulmonary oedema

ECG

Body Stuffers should be observed for signs of toxicity for a minimum 6 hours, consider activated Charcoal

Body Packers with positive imaging who are asymptomatic can be discharged back to police custody for monitoring. Bowel preparation such as Cleanprep or movicol can be used.

Toxidromes should be treated as per toxbase guidelines Toxbase

Body Packers with signs of cocaine or amphetamine toxicity or signs of obstruction/ileus require urgent surgical intervention.

Body packers with signs of Heroin toxicity should be treated with Naloxone infusion as per toxbase guidelines

Delirium in the ED

Delirium is one of a number of geriatric syndromes and has significant associated morbidity and mortality.

3 subtypes of delirium

  1. Hyperactive – easies to spot, one we are most familiar with. Characterised by agitation/aggression/hallucinations “the non cooperative patient”
  2. Hypoactive – harder to spot. Characterised by drowsiness, less responsive, vacant, sleeping more at home
  3. Mixed

Remember there is NO SUCH THING AS A “POOR HISTORIAN” !! – Just a poor clinician! If your patient is not cooperating and can’t tell you very much then you need to find out why!!! Read more

Paediatric Mental Health

The provision of out of hours mental health services for Children and young people (under the age of 18) is changing: –

Between 8pm and 9am the onsite Mental Health Liason team (RAID) will see these patients initally and help with the mental health aspects of their care. Between 9am and 8pm contact CAMHS via switchboard as normal.

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
