Immediate priorities
Initial stabilization
Airway risk
Depressed mental status
Recurrent seizures
Severe agitation requiring control
Breathing risk
Hypoventilation
Aspiration risk
Circulation risk
Hypotension
Wide-complex tachycardia
Ventricular dysrhythmia
Monitoring and access
Cardiac monitor
12-lead ECG within 10 minutes
IV access x2
Temperature
Point-of-care glucose
Early tox strategy
High-risk features
QRS duration 100 ms or more
Ventricular dysrhythmia
Hypotension refractory to fluids
Seizure
Coma
Early consultation triggers
Poison centre
Critical care
Cardiology for refractory dysrhythmia
ECMO-capable centre for refractory shock
ECG-first risk stratification
ECG danger markers
QRS widening
QRS 100 ms or more predicts higher seizure risk
QRS 160 ms or more predicts higher ventricular dysrhythmia risk
aVR terminal R wave prominence
R in aVR 3 mm or more
R to S ratio in aVR greater than 0.7
QTc prolongation
Torsades risk context
Rightward terminal QRS axis
Terminal 40 ms axis rightward shift
Immediate bedside decision points
Time-critical branching
If QRS 100 ms or more
Sodium bicarbonate bolus strategy
pH target 7.50 to 7.55
If seizure
Benzodiazepine first-line
Sodium bicarbonate if concurrent QRS widening or instability
If hypotension
Crystalloid bolus
Norepinephrine early for refractory hypotension
If ventricular dysrhythmia
Sodium bicarbonate escalation
Lidocaine consideration
Avoid class Ia and Ic agents
