🚨 Dental Medical Emergency Protocol

Chairside decision support for 14 medical emergencies in the dental clinic — recognition, step-by-step management, drug doses, and ambulance triggers. Based on Resuscitation Council UK 2021 guidelines.

Clinical Reference Only — Not a Substitute for Training
CRITICAL — Call 999 immediately URGENT — May need ambulance IMPORTANT — Monitor closely COMMON — Usually self-limiting

Per Resuscitation Council UK (2021) and GDC Standards for the Dental Team — Standard 9.3

🫁 Airway & Breathing

  • ✓Portable oxygen cylinder — min 500 L (size D/CD); with flow-control valve
  • ✓Non-rebreather face mask — 10–15 L/min for high-flow oxygen
  • ✓Nasal cannula — 2–4 L/min for low-flow supplemental O₂
  • ✓Pocket mask with one-way valve — rescue breathing
  • ✓Bag-valve-mask (BVM) — adult size; preferred over pocket mask for trained operators
  • ✓Oropharyngeal airways (Guedel) — sizes 0, 1, 2, 3, 4
  • ✓Suction apparatus with Yankauer catheter

❤️ Circulation & Monitoring

  • ✓AED (Automated External Defibrillator) — accessible within 3 minutes
  • ✓Pulse oximeter — SpO₂ and pulse rate
  • ✓Sphygmomanometer — manual or digital BP cuff
  • ✓Blood glucose monitor (glucometer) with test strips and lancets
  • ○IV cannulae (18G, 20G) + tourniquet — recommended for practices with trained staff
  • ○IV giving set + 0.9% saline 500mL — fluid challenge for anaphylaxis/adrenal crisis

💉 Drug Administration

  • ✓Syringes (2mL, 5mL, 10mL) + needles (21G, 23G)
  • ✓Sharps bin — for post-injection disposal
  • ✓Alcohol wipes

📋 Admin & Safety

  • ✓Emergency contact list — posted at reception and surgery
  • ✓Emergency protocol cards — laminated, stored in the emergency kit box
  • ✓Patient medical history form — updated at each visit, accessible at chairside
Maintenance: Check oxygen cylinder level monthly. Check drug expiry dates every 3 months. Inspect AED pads and battery indicator monthly. Document all checks.

Frequently Asked Questions

What is the most common medical emergency in the dental clinic?
Vasovagal syncope (fainting) is the most common, accounting for approximately 50% of all dental medical emergencies. It is triggered by anxiety, pain, sight of blood, or prolonged fasting. Management: lay flat with legs elevated, ensure airway, give oxygen, monitor. Most patients recover within 2–3 minutes without medication.
When must I call 999 immediately?
Call 999/112 immediately for: cardiac arrest, anaphylaxis, suspected acute MI, stroke/TIA, severe asthma not responding to salbutamol, adrenal crisis, local anaesthetic systemic toxicity (LAST), and any seizure lasting more than 5 minutes. Do not delay — these are time-critical emergencies where every minute affects outcome.
What are the minimum emergency drugs required in a UK dental practice?
The Resuscitation Council UK (2021) specifies: Adrenaline 1mg/mL (ampoules), Aspirin 300mg dispersible, GTN spray 400mcg/dose, Salbutamol inhaler 100mcg, oral glucose (Glucogel), Glucagon 1mg kit, Midazolam buccal 10mg/2mL, and Hydrocortisone 100mg. Drug expiry must be checked every 3 months and documented.
How often should the dental team practise medical emergencies?
The GDC and Resuscitation Council UK recommend that all dental team members practise medical emergency scenarios at least annually, including basic life support (BLS) with AED use. Many practices conduct simulated emergency drills every 6 months. CPR training should be updated every 2 years with an accredited provider.
How do I give adrenaline for anaphylaxis in the dental clinic?
Draw up 0.5mL of Adrenaline 1mg/mL (1:1000) into a 1mL syringe. Inject intramuscularly into the anterolateral thigh (outer mid-thigh) through clothing if necessary. This is the fastest route with most reliable absorption. Do not give subcutaneously or IV unless in cardiac arrest. Repeat every 5 minutes if no improvement while awaiting ambulance.
What is LAST (Local Anaesthetic Systemic Toxicity) and how is it managed?
LAST occurs when local anaesthetic enters the bloodstream in toxic concentrations, typically from intravascular injection or dose excess. Early signs: perioral numbness, tinnitus, metallic taste, agitation. Late signs: seizures, cardiovascular collapse. Management: stop the injection immediately, call 999, give O₂, secure IV access, give midazolam for seizures. Intralipid 20% (1.5mL/kg IV) is the specific antidote — recommended in advanced settings or if cardiac arrest occurs.
