General
- Type: Lipid emulsion therapy
- Dosage Forms: 10%, 20%, and 30% lipid emulsions
- Note that 20% is used for lipid rescue therapy for systemic drug toxicity[1]
- Routes of Administration: IV
- Common Trade Names: Intralipid, Lipid Rescue [2]
Adult Dosing
Note that dosing for adults and children is not standardized but is based on case reports and recommendations[3]
Persistent Cardiovascular Collapse
- May repeat bolus once or twice for persistent cardiovascular collapse[8]
- May double rate of infusion to 0.5 mL/kg/min for persistent hypotension[9]
- Max cumulative dose: 12 ml/kg
After Cardiovascular Stability Achieved
- Maintain infusion for at least 10 minutes[10]
Simplified Protocol[11]
- Based on 'average' 70 kg patient
- 100 mL IV bolus over 1 minute
- Infusion at 18 mL/h IV
Pediatric Dosing
As with adults, pediatric dosing is not standardized[12]
- Initial bolus of 0.8 - 3 mL/kg[13]
- No recommendations provided for rate of ongoing infusion
Special Populations
- Pregnancy Rating: C
- Lactation risk:
- Renal Dosing
- Adult
- Pediatric
- Hepatic Dosing
- Adult
- Pediatric
Emergency department indications[14][15]
- Severe systemic drug toxicity plus:
- Persistent hemodynamic instability
- All conventional options have been exhausted
- Toxicity has poor prognosis
- Common toxicities
Contraindications
- Allergy to class/drug
Adverse Reactions
Serious
- Asystole (case reported) [16]
- Fat embolism
- Hypersensitivity reactions
- ARDS
Common
- Pancreatitis[17]
- Hypertriglyceridemia[17]
- Interferes with some lab measurements
- Glucose and magnesium concentrations become inaccurate
- Creatinine and lipase become unmeasurable
Pharmacology
- Half-life:
- Metabolism:
- Excretion:
- Mechanism of Action:
- Unclear, but proposed mechanisms include[18]:
- Lipid sink/partition
- Emulsion surrounds lipophilic drug molecule, partitioning it from target organs
- Cardiac metabolism
- Fatty acids provide the myocardium with a ready energy source, improving cardiac contractility
- Lipid sink/partition
- Unclear, but proposed mechanisms include[18]:
Comments
- Avoid co-administration of:[19]
Indications by Condition
The following table is automatically generated from disease/condition pages across WikEM.
| Indication | Dose | Context | Route | Population | |
|---|---|---|---|---|---|
| Beta-blocker toxicity#Intralipid Lipid emulsion therapy Adult | Beta-blocker toxicity | 1.5 mL/kg IV bolus of 20%, then 0.25 mL/kg/min for 30-60 min | Lipid emulsion therapy | IV/IV drip | Adult |
| Calcium channel blocker toxicity#Intralipid Lipid emulsion therapy Adult | Calcium channel blocker toxicity | 1.5 mL/kg IV bolus of 20% lipid, then 0.25 mL/kg/min | Lipid emulsion therapy | IV/IV drip | Adult |
| Local anesthetic systemic toxicity#Intralipid Lipid emulsion therapy (20% solution) Adult | Local anesthetic systemic toxicity | 1.5 mL/kg IV bolus over 1 min, then 0.25 mL/kg/min x20 min (increase to 0.5 mL/kg/min if declining) | Lipid emulsion therapy (20% solution) | IV/IV drip | Adult |
