- Emergency department indications: Local anesthetic systemic toxicity, refractory hemodynamic instability secondary to ingestion of cardiodepressive medications / toxins (i.e. Beta blocker or Calcium Channel Blocker)
Adult Dosing
- 1.5 ml/kg bolus[1]
- Followed by 0.25 ml/kg/min for 20 min or until hemodynamic stability is achieved.[2]

Adverse Reactions
Serious
- Asystole (case reported) [3]
- Fat embolism
- Hypersensitivity reactions
Common
- Pancreatitis[4]
- Hypertriglyceridemia[4]
- Interferes with some lab measurements
- Glucose and magnesium concentrations become inaccurate
- Creatinine and lipase become unmeasurable
Pharmacology
- Half-life:
- Metabolism:
- Excretion:
- Mechanism of Action:
- Emulsion acts as a “lipid sink,” surrounding a lipophilic drug molecule and rendering it ineffective
- Fatty acids from the ILE provide the myocardium with a ready energy source, improving cardiac function
