Intralipid® 20% for Local Anesthetic Reversal
What You Need to Know Before You Apply
What is the purpose of this trial?
In order to determine if Intralipid 20% can be used to reverse the effects of local anesthetics, the investigators will recruit 18 volunteers who will be asked to come to HSS for two study visits. Small amounts of local anesthetics will be injected into the volunteers' thighs during both visits. During one visit volunteers will receive Intralipid 20% and during the other visit they will receive a saline solution. The study team will measure how quickly normal sensation returns to the thighs when the volunteers get Intralipid 20% compared to saline.
Will I have to stop taking my current medications?
The trial requires that you do not use drugs that affect the sensorium, such as opioids, benzodiazepines, antipsychotics, and gabapentinoids.
Is Intralipid® 20% safe for use in humans?
Intralipid® 20% has been used safely in humans to treat toxicities from local anesthetics and other drugs, with case reports showing successful outcomes in reversing drug overdoses. It is considered a standard treatment for severe local anesthetic toxicity, suggesting a favorable safety profile in these contexts.12345
How does Intralipid® 20% differ from other treatments for local anesthetic toxicity?
Intralipid® 20% is unique because it acts as a 'lipid sink' to absorb and neutralize local anesthetics in the bloodstream, which is different from traditional resuscitation methods that do not specifically target the anesthetic itself. This lipid emulsion is administered intravenously and is particularly used when other treatments fail to reverse the toxicity.34567
What data supports the effectiveness of the drug Intralipid 20% Solution for reversing local anesthetic toxicity?
Intralipid 20% Solution has been shown to be effective in treating local anesthetic toxicity, as it is recommended as a first-line treatment by several international anesthesia organizations. Additionally, case reports have documented successful reversal of local anesthetic-induced toxicity using Intralipid, and it has also been effective in treating toxicities from other drug classes.13678
