Summary
Local anesthetics are widely used, but overdose can cause systemic toxicity. Recent research clarifies the causes of Local Anesthetic Systemic Toxicity (LAST) and the effectiveness of lipid emulsion therapy.
Area of Science:
- Anesthesiology
- Pharmacology
- Toxicology
Background:
- Local anesthetics are essential in medical practice, yet their systemic toxicity from overdose is not well understood.
- Recent research has focused on the causes and treatment of Local Anesthetic Systemic Toxicity (LAST).
Purpose of the Study:
- To increase awareness of Local Anesthetic Systemic Toxicity (LAST).
- To establish protocols for managing severe neurotoxicity and cardiotoxicity associated with LAST.
Main Methods:
- Review of recent research on the etiology of LAST.
- Evaluation of the role of lipid emulsion in treating LAST.
Main Results:
- Understanding of the mechanisms underlying LAST has advanced.
- Lipid emulsion therapy has shown promise in managing LAST.
Conclusions:
- Increased awareness and standardized treatment protocols for LAST are crucial.
- Effective management of LAST can mitigate severe neurological and cardiac complications.

1.0K
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:13Local Anesthetics: Pharmacokinetics
1.5K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
2.0K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
