Clinical assessment and specified intervention (A to G)
If the patient has any Yellow or Red Zone observations or additional criteria (as per the relevant NSW Standard Emergency Observation Chart), refer and escalate as per local CERS protocol and continue treatment.
Position
Assessment | Intervention |
---|---|
General appearance/first impressions | Position of comfort Minimise stress by providing a quiet, calm, safe and private space Keep intoxicated patients under close observation until their intoxication diminishes and they are considered safe De-escalation techniques may be required for patients experiencing agitation or distress |
Airway
Assessment | Intervention |
---|---|
Patency of airway | Maintain airway patency Consider airway opening manoeuvres and positioning |
Breathing
Assessment | Intervention |
---|---|
Respiratory rate and effort Auscultate chest (breath sounds) Oxygen saturation (SpO2) | Assist ventilation, as clinically indicated Consider oxygen if dyspnoeic, titrate oxygen to maintain SpO2 over 93% Patients at risk of hypercapnia, maintain SpO2 at 88–92% Monitor closely for aspiration pneumonia and/or respiratory depression |
Circulation
Assessment | Intervention |
---|---|
Perfusion (capillary refill, skin warmth and colour) Pulse Blood pressure Cardiac rhythm | Assess circulation Attach cardiac monitor and complete 12 lead ECG if BP/HR are within the Yellow or Red Zones, or where clinically relevant e.g. irregular pulse, palpitations, syncope, shock, respiratory compromise, cardiac history or clinical concern |
IVC and/or pathology | Insert IV cannula, if trained and clinically indicated If unable to obtain IV access, consider intraosseous, if trained |
Signs of shock: tachycardia and CRT 3 seconds and over and/or abnormal skin perfusion and/or hypotension | If signs of shock present and/or SBP less than 90 mmHg, give 250 mL of sodium chloride 0.9% IV/intraosseous bolus Repeat every 10 minutes (up to 1000 mL) until SBP over 90 mmHg or signs of shock have resolved |
Disability
Assessment | Intervention |
---|---|
GCS, pupillary response and limb strength | Obtain baseline and repeat assessment as clinically indicated |
Pain | Assess pain. If indicated, give early analgesia as per specific treatment section then resume A to G assessment |
Exposure
Assessment | Intervention |
---|---|
Temperature – pyrexia is common in acute withdrawal | Measure temperature Maintain normothermia |
Skin inspection, including posterior surfaces | Check and document any abnormalities |
Fluids
Assessment | Intervention |
---|---|
Hydration status: last ate, drank, bowels opened, passed urine or vomited | Commence fluid balance chart, as required Encourage oral hydration |
Nausea and/or vomiting | If present, see nausea and/or vomiting section |
Glucose
Assessment | Intervention |
---|---|
BGL |
Measure BGL If patient is experiencing alcohol withdrawal or is at high risk of thiamine deficiency and is hypoglycaemic: give thiamine before glucose, or as soon as possible after. See thiamine section If BGL less than 4 mmol/L with NO decrease in level of consciousness (Yellow Zone criteria):
If BGL less than 4 mmol/L WITH a decrease in level of consciousness (Red Zone criteria) OR the patient is unable to tolerate oral intake:
If the patient is unconscious or peri-arrest:
Once stabilised, give patient long-acting carbohydrate and continue to check BGL hourly, or as clinically indicated |
Repeat and document assessment and observations to monitor responses to interventions, identify developing trends and clinical deterioration. Escalate care as required according to the local CERS protocol.
Focused assessment
Complete substance withdrawal focused assessment.
Consider mental health focused assessment.
Clinical tips are provided in Management of Withdrawal from Alcohol and Other Drugs Clinical Guidance to support clinicians to provide care that meets the needs of patients from specific population groups undergoing substance withdrawal.
Precautions and notes
- Be familiar with any new or recent drug alerts available at Public drug warnings, NSW Health.
- Determine if the patient is currently a client of other service providers, and the need for their input while patient is in the emergency department.
- Delirium tremens (DTs) begins 48–72 hours after the last drink. DTs have serious medically associated risks, including changes to breathing, blood circulation, core body temperature and electrolytes.
- Thiamine is an essential vitamin in the body’s metabolic processes. Malnutrition is high in people with alcohol and drug dependence. Failure to restore thiamine can lead to Wernicke-Korsakoff syndrome or Wernicke encephalopathy.
Interventions and diagnostics
Specific treatment
- Continue to monitor and assess withdrawal symptoms, using appropriate opioid or alcohol withdrawal scale
- Refer to local drug and alcohol service promptly, if available
For patients less than 65 years and not pregnant:
- give diazepam 10 mg orally once only. Escalation is required for ongoing management
- continue hourly withdrawal scale and monitoring
- switch to acute behavioural disturbance protocol if required.
Analgesia
If pain score 1–6 (mild–moderate): give paracetamol 1000 mg orally once only.
If severe pain present, give analgesia and escalate as per local CERS protocol.
Nausea and/or vomiting
If nausea and/or vomiting is present, give:
- metoclopramide 10 mg orally or IV/IM once only (over 20 years only)
- or ondansetron 4 mg orally or IV/IM. If symptoms persist after 60 minutes, repeat once, maximum dose 8 mg
- or prochlorperazine 5 mg orally once only or 12.5 mg IV/IM once only
Choice of antiemetic should be determined by cause of symptoms.
Thiamine
If patient is experiencing alcohol withdrawal, or is at high risk of thiamine deficiency (e.g. those who drink large amounts of alcohol or who are severely malnourished), then:
- monitor using alcohol withdrawal scale
- give thiamine 300 mg IV/IM once only
If hypoglycaemic: thiamine should be given before glucose, or as soon as possible. Glucose can further deplete thiamine stores and precipitate Wernicke encephalopathy.
Radiology
Not usually indicated. If there is concern for urgent radiology, escalate care as per local CERS protocol.
Pathology
- FBC, UEC, LFT
- Alcohol withdrawal: coags
