MTS is widely adopted across GCC EDs. Some facilities use a 3-level or 4-level system — confirm local policy.
MTS 1–2, cardiac arrest, major trauma, severe respiratory distress, altered consciousness.
MTS 2–3, moderate-severity illness, requires investigations, monitoring >2 hours likely.
MTS 3–5, ambulatory patients, minor injuries, simple presentations. Target: see and treat <4h.
MTS 4–5 with no acute pathology — consider redirect to polyclinic (Aster, NMC, DHA clinics). Document refusal if patient declines redirect.
| Score | Status | Action |
|---|---|---|
| 0–20 | Not Crowded | Routine operations |
| 21–60 | Busy | Monitor, maintain flow |
| 61–100 | Overcrowded | Bed manager alert, expedite discharges |
| 101–140 | Severely OC | Escalate to hospital command, consider divert |
| >140 | Dangerously OC | Code census / Major Incident protocol |
Admitted patients held in ED awaiting inpatient bed. Target: <4h boarding time. Boarding nurse assigned; handover documents completed even while boarding.
Patent? Speaking in full sentences? Stridor / gurgling / snoring? Jaw thrust if C-spine risk. Suction if secretions. Consider OPA/NPA. Intubation if GCS ≤8 or unprotected airway.
RR, SpO₂, chest rise symmetry, auscultation, trachea midline, accessory muscle use. O₂ target SpO₂ 94–98% (88–92% in COPD). 15L/min NRB mask if compromised.
HR, BP, cap refill, skin colour/temperature, JVP. IV access ×2 large-bore. Bloods: FBC, UEC, LFTs, coags, troponin, VBG, group & hold. 250ml–500ml NS bolus if hypotensive.
GCS (E/V/M), pupils (size, reactivity, equality), BGL (capillary glucose — treat hypoglycaemia <4 mmol/L immediately), posture, focal neuro deficit.
Full exposure — log roll, inspect back, perineum, axillae. Maintain dignity. Temperature (rectal if accurate needed). Document all injuries / skin findings.
| Drug | Role | Typical Dose |
|---|---|---|
| Fentanyl | Pre-medication (attenuate pressor response) | 1–3 mcg/kg IV |
| Ketamine | Induction (haemodynamically stable) | 1–2 mg/kg IV |
| Propofol | Induction (avoid if hypotensive) | 1–2 mg/kg IV |
| Suxamethonium | Paralytic (depolarising, 60s onset) | 1.5 mg/kg IV |
| Rocuronium | Paralytic (non-depol, use if sux CI) | 1.2 mg/kg IV |
Sellick manoeuvre: posterior pressure on cricoid ring to occlude oesophagus. Controversial — may worsen laryngoscopy view.
BURP: Backwards-Upwards-Right Pressure on thyroid cartilage to optimise laryngoscopy view — preferred technique by laryngoscopist.
| Drug | Indication | Dose | Notes |
|---|---|---|---|
| Noradrenaline | Septic / distributive shock (1st line) | 0.01–1 mcg/kg/min IV infusion | Central line preferred; can start peripheral short-term |
| Adrenaline (Anaphylaxis) | Anaphylaxis | 0.5mg (500mcg) 1:1,000 IM anterolateral thigh | Repeat q5–15 min if no response. Never IV bolus for anaphylaxis unless cardiac arrest |
| Adrenaline (Arrest) | Cardiac arrest (PEA/Asystole/VF) | 1mg (1:10,000) IV q3–5 min | After 2nd shock in shockable rhythm; every cycle in non-shockable |
| Dopamine | Cardiogenic shock, bradycardia | 2–20 mcg/kg/min IV infusion | Low dose dopaminergic; mid dose inotropic; high dose vasopressor. Largely replaced by NA/adrenaline |
| Drug | Key Features | Dose (Procedural) | Cautions |
|---|---|---|---|
| Ketamine | Dissociative; preserves airway reflexes & BP; bronchodilator | 1–1.5 mg/kg IV or 4 mg/kg IM | Emergence reactions (co-give midazolam); raises ICP — use caution in head injury; laryngospasm rare |
| Propofol | Rapid onset/offset; anti-emetic; excellent sedation quality | 0.5–1 mg/kg IV (titrate) | Apnoea & hypotension risk — airway equipment mandatory; pain on injection; propofol infusion syndrome (ICU doses) |
| Midazolam | Anxiolytic, amnestic, anticonvulsant | 0.02–0.05 mg/kg IV slowly | Respiratory depression; accumulates in elderly/renal failure; reversal: flumazenil (rarely used) |
| Drug | Indication | Dose | Notes |
|---|---|---|---|
| Lorazepam | Status epilepticus — 1st line | 0.1 mg/kg IV (max 4mg) — repeat ×1 | Preferred benzodiazepine for status; slow onset if IM |
| Diazepam IV | Status epilepticus — alternative | 0.15 mg/kg IV (max 10mg) | Rectal diazepam 0.5 mg/kg if no IV access |
| Levetiracetam | 2nd line / maintenance after benzodiazepines | 60 mg/kg IV over 10 min (max 4.5g) | Fewer drug interactions than phenytoin; safe in liver disease; IV levetiracetam (Keppra) increasingly used in GCC EDs |
| Sodium Valproate | Status epilepticus — 2nd line | 40 mg/kg IV over 10 min (max 3g) | Avoid in liver disease, pregnancy (teratogenic) |
| Antidote | Toxin | Dose | Key Points |
|---|---|---|---|
| Naloxone | Opioid overdose | 0.4mg IV/IM/IN; repeat q2–3 min; infusion if needed | Titrate to adequate respiration — NOT to full consciousness. Short half-life (30–90 min) — may need repeat doses or infusion. Monitor for re-sedation. |
| Flumazenil | Benzodiazepine reversal | 0.2mg IV q1 min; max 1mg | Rarely used — may precipitate seizures in benzo-dependent patients or mixed overdoses. NOT routine. Call toxicology. |
| N-Acetylcysteine (NAC) | Paracetamol overdose | IV: 150mg/kg in 200ml D5W over 1h, then 50mg/kg over 4h, then 100mg/kg over 16h | Rumack-Matthew nomogram — plot serum paracetamol vs time since ingestion (≥4h). Treat if above treatment line. See interactive tool below. |
| Atropine | Organophosphate / bradycardia | 1–3mg IV; repeat until secretions dry (OPC) | Large doses required in organophosphate poisoning (up to 20mg+). Endpoint: dry secretions, not tachycardia. |
| Agent | Indication | Time Target | Dose |
|---|---|---|---|
| Alteplase (tPA) | STEMI (if PCI not available within 120 min) | Door-to-needle <30 min | 15mg IV bolus → 0.75 mg/kg over 30 min → 0.5 mg/kg over 60 min (max 100mg) |
| Alteplase (tPA) | Ischaemic stroke | Door-to-needle <60 min; onset <4.5h | 0.9 mg/kg (max 90mg); 10% as bolus, 90% over 60 min |
| Tenecteplase (TNK) | STEMI (preferred, single bolus) | Door-to-needle <30 min | Weight-based IV bolus (30–50mg by weight band) |
Estimate treatment line threshold: serum paracetamol vs hours post-ingestion. Use for single acute ingestion.
HEART Score: History / ECG / Age / Risk Factors / Troponin — see interactive calculator below.
Wells PE Score: DVT signs, HR>100, immobilisation, prior PE/DVT, haemoptysis, active cancer, PE most likely dx. Score <2 = low; 2–6 = moderate; >6 = high.
Stanford Aortic Dissection: high-risk features (pain character, pulse deficit, BP differential, wide mediastinum) — CTA chest-abdomen-pelvis urgently.
1 point each: RR ≥22/min | Altered mentation (GCS <15) | SBP ≤100 mmHg
Score ≥2 = high suspicion for sepsis → full assessment
Life-threatening organ dysfunction caused by dysregulated host response to infection. SOFA score increase ≥2 from baseline.
Septic Shock: Vasopressor needed to maintain MAP ≥65 mmHg AND lactate >2 mmol/L despite adequate fluid resuscitation.

Preferred in suspected C-spine injury. Fingers at angle of mandible, push jaw forward. Maintains neutral C-spine alignment.
Sizing: corner of mouth to earlobe. Insert inverted (concave upward) then rotate 180° in adults. Do NOT use if gag reflex present.
Sizing: 6–9 Fr (♂ 7–9, ♀ 6–7). Lubricate well. Insert along nasal floor, bevelled edge toward septum. Safe with intact gag reflex. Avoid if base-of-skull fracture suspected.
RTA remains the leading cause of trauma ED presentations across the GCC. Contributing factors include high-speed limit roads (120–140 km/h), historical low seatbelt compliance (though improving with enforcement), mobile phone use while driving, and large numbers of heavy vehicles.
UAE summer temperatures routinely exceed 45°C with high humidity. Heat stroke is a medical emergency with mortality up to 50% if untreated.
GCC hosts major mass gathering events requiring surge planning and dedicated medical resources.
The GCC ED serves a highly diverse population — over 180 nationalities in Dubai alone. Language barriers are a significant patient safety risk.
Most GCC countries follow international 5-level colour triage aligned with MTS or CTAS:
| Colour | Level | Used In |
|---|---|---|
| Red | Immediate (1) | UAE, KSA, Qatar, Bahrain |
| Orange | Very Urgent (2) | UAE (MTS), KSA (CTAS-aligned) |
| Yellow | Urgent (3) | All GCC |
| Green | Standard (4) | All GCC |
| Blue | Non-Urgent (5) | UAE, Qatar |
