Toxicity of local anesthetics in infants and children
1Harvard Medical School, Boston, Massachusetts.
Insights
Local anesthetics offer safe pain relief for children when used correctly. Adhering to dosage limits and avoiding accidental injections are crucial for preventing toxicity in pediatric patients.
Area of Science:
- Pediatric Anesthesiology
- Pharmacology
- Clinical Toxicology
Background:
- Local anesthetics are widely used for anesthesia and analgesia in pediatric patients.
- Despite a good safety record, toxicity concerns necessitate careful administration.
- Safe use requires understanding systemic drug handling and dosage limits.
Purpose of the Study:
- To review the safe use of local anesthetics in pediatrics.
- To highlight potential toxicity issues and their causes.
- To emphasize the importance of adhering to strict dosage guidelines.
Main Methods:
- Review of existing literature on local anesthetic toxicity in children.
- Analysis of factors contributing to adverse events.
- Emphasis on quantitative dosing strategies.
Main Results:
- Most toxic reactions result from inadvertent intravascular injection or overdosage.
- Systemic uptake, distribution, and clearance significantly influence toxicity.
- Unlike opioids, local anesthetics require precise dose limitation.
Conclusions:
- Local anesthetic administration within established safety guidelines should be encouraged in pediatrics.
- Healthcare providers must be informed about dosage limits and toxicity management.
- Strict adherence to quantitative limits is essential for safe pediatric use.
Abstract:
Local anesthetics are extremely useful for providing anesthesia and analgesia for infants and children of all ages. Despite the toxicity issues raised here, the overall safety record of local anesthetic use in pediatrics has been very good, and local anesthetic administration within safe guidelines should be encouraged. In the great majority of cases, toxic reactions have been associated with either inadvertent intravascular injection or unintentional overdosage by physicians who did not adequately consider issues related to systemic drug uptake, distribution, or clearance. Unlike opioids, which can be titrated according to clinical signs to a wide range of doses, local anesthetic administration must be strictly limited "by the numbers." Pediatricians, surgeons, emergency room physicians, and anesthesiologists need to be informed regarding limits for the administration of local anesthetics and management of toxic reactions.
