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.
  • Account for 1.4 million ED attendances each year, 95% of these are minor head injuries that can be managed in the ED.

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 – treat as per Toxbase

  • 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

 

Toxicology screens (urinary/blood) should not be used to guide management or discharge decisions (Level 5 evidence).

 

Body Stuffers & Pushers should be observed for signs of toxicity for a minimum 8 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.

 

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

All patients transferred to police custody should receive a discharge letter, including
Suspected Internal Drug Traffickers.

Hypertensive Disorders in Pregnancy

  • New onset hypertension after 20 weeks of gestation (systolic blood pressure > 140 and/or diastolic blood pressure > 90)

And either

  • Proteinuria (urine protein:creatinine ratio ≥30mg/mmol)

Or

  • Other features of pre-eclampsia1:
    • AKI (creatinine ≥ 90)
    • Liver dysfunction (ALT>40)/epigastric/RUQ pain
    • New severe persistent headache without an alternative diagnosis
    • Persistent visual disturbance
    • Haematological complications (platelets <150/DIC/haemolysis)
    • Neurological complications (clonus/stroke/seizures(eclampsia))
    • Pulmonary oedema
    • Uteroplacental dysfunction (fetal growth restriction/placental abruption/intrauterine death)

Onset is usually after 20 weeks of gestation, but it can also occur up to a few weeks postpartum.

Eclampsia- This is pre-eclampsia that has progressed to seizures

Risk Factors:

Clinical features of pre-eclampsia:

  • Asymptomatic hypertension (picked up on screening or incidentally when presenting with another issue)
  • Headache (usually frontal)
  • RUQ or epigastric pain (also a symptom of HELLP syndrome)
  • Nausea and vomiting
  • Oedema (common but not specific). Especially if rapidly increasing and involving face and hands.
  • Visual disturbance (flashing lights in the visual fields or scotomata)
  • Shortness of breath (uncommon but can occur due to pulmonary oedema)
  • Hyper-reflexia and/or clonus

HELLP syndrome is a variant of severe pre-eclampsia characterised by haemolysis, elevated liver enzymes and low platelets.4

Symptoms and signs are similar to those of pre-eclampsia but also include jaundice and bleeding.

Management of Pre-eclampsia:

 

  • Contact obstetrics early
  • Manage the patient in an area with close monitoring if pre-eclampsia with severe features
  • BP management:
    • Labetalol first line unless unsuitable or contraindicated3 (e.g. asthma)
    • Nifedipine MR second line
    • Methyldopa third line (not used postpartum due to risk of depression)
  • Careful fluid balance monitoring
    • Fluid restriction to reduce the risk of pulmonary oedema
    • Monitor urine output if severe
  • Consider IV magnesium sulphate for eclampsia prophylaxis if severe features of pre-eclampsia

Definitive management:

Definitive management of pre-eclampsia is ultimately delivery of the fetus.   Timing of delivery will be decided by senior members of the obstetric team according to the severity of pre-eclampsia, the current gestation and in consultation with the patient. Following diagnosis of pre-eclampsia, the majority of women are managed as inpatients until delivery.

 

ED Management of Eclampsia:

  • Ask for help early from ITU and obstetric teams
  • ABC approach, manage in left lateral position
  • Airway and breathing assessment with high flow oxygen
  • If inadequate ventilation, consider early intubation (laryngeal oedema in pre-eclampsia and increased risk of aspiration in pregnancy)
  • Magnesium sulphate IV is treatment of choice for seizures – 4g loading dose over 5-10 mins then 1g/hr infusion for 24 hours
  • Further 2g boluses of magnesium sulphate can be given if further seizures occur after initial loading.3
  • Patients will need to be managed in HDU/ITU to stabilise blood pressure prior to delivery

Opioid Toxicity

Opioid Toxicity causes:

  1. Drowsiness
  2. Respiratory Depression – Hypo-ventilation and decreased respiratory rate
  3. Pupillary Miosis

Other Symptoms may include (but are not diagnostic or opioid toxicity):

  • Nausea and vomiting
  •  Neuropsychiatric features including nightmares, anxiety, agitation, euphoria, dysphoria,
    depression, paranoia and hallucinations
  •  Urticaria and pruritis
  •  Convulsions
  •  Hypotension and bradycardia
  •  Hypothermia secondary to environmental exposure

Naloxone is the antidote to Opioids however as these are commonly co-ingested with other depressants. full reversal of symptoms may not occur with treatment.

In acute opioid toxicity, the aim of naloxone administration should be reversal of respiratory depression and maintenance of airway protective reflexes, not full reversal of unconsciousness.

 

Opioid Toxicity Treatment

Naloxone infusion if required is based on the total dose given to obtain Respiratory rate of 10

Suspected Cauda Equina Syndrome CES

1. Red Flags: Has the patient developed any of the following?

  • Difficulty initiating micturition or impaired sensation of urinary flow
  • Altered perianal, perineal or genital sensation S2-S5 dermatomes – area may be small or as big as a horses’ saddle (subjectively reports or objectively tested)
  • Severe or progressive neurological deficit of both legs, such as major motor weakness with knee extension, ankle eversion, or foot dorsiflexion
  • Loss of sensation of rectal fullness
  • Sexual dysfunction (achievement of erection or ability to ejaculate, loss of genital sensation)

If Yes to ANY proceed to 2.

If NO to ALL consider other diagnosis and possibility of GP follow-up

Primary Intracerebral Haemorrhage

In anybody who there is suspicion of a non-traumatic haemorrhage arrange an urgent CT Head.

All patients need IV access and  U&E, FBC, Coag

If CT confirms PICH (not traumatic, not SAH): –

Anticoagulation

If anticoagulated with warfarin or NOAC discuss with stroke consultant and Haematologist regarding reversal

If not anticoagulated give Tranexamic acid – 1g in 100mls Saline/Glucose over 10 mins followed by 1g in 250mls Saline over 6 hours.

Blood Pressure

BP needs to be <150/80 – use labetalol (max 400mg – until BP <160 or HR <50) and GTN infusion

Neurosurgical Referral

Not all patients with intracerebral bleeds need referral to neurosurgery – you could save yourself and your patient a lot of time and effort!

Those to refer:

  • GCS 9-12/15 with lobar haemorrhage
  • Isolated intraventricual haemorrhage
  • Hydrocephalus on presentation
  • Rapid deterioration following arrival (gcs drop by 2 points or more in the motor component)
  • Cerebellar bleed

Admit those not going to Neurosurgery to HASU at CRH after discussion with Stroke team
