Insights
Three infants experienced systemic lidocaine toxicity after subcutaneous lidocaine for circumcision anesthesia. All infants had seizures but recovered fully with supportive care, highlighting potential risks of local anesthetics in neonates.
Area of Science:
- Pediatric Anesthesiology
- Clinical Toxicology
- Neonatal Medicine
Background:
- Regional anesthesia using lidocaine is common for elective infant circumcision.
- Systemic lidocaine toxicity can occur following regional anesthesia.
- Monitoring for adverse events is crucial in pediatric anesthesia.
Observation:
- Three previously healthy infants (23 days, 6 weeks, 3 months) developed systemic lidocaine toxicity.
- Toxicity occurred after subcutaneous lidocaine administration for regional anesthesia during circumcision.
- All infants presented with generalized seizures requiring endotracheal intubation.
Findings:
- The infants experienced severe central nervous system toxicity.
- Full recovery was achieved with comprehensive supportive care.
- This indicates the potential for significant adverse events even with standard procedures.
Implications:
- Subcutaneous lidocaine administration for regional anesthesia in infants carries a risk of systemic toxicity.
- Prompt recognition and supportive care are vital for managing lidocaine-induced seizures in neonates.
- Further research into safer anesthetic techniques or dosing for infant circumcision may be warranted.
Abstract:
We report three previously healthy infants aged, respectively, 23 days, 6 weeks, and 3 months with systemic lidocaine toxicity following administration of subcutaneous lidocaine for regional anesthesia during an elective circumcision. The patients developed a generalized seizure requiring endotracheal intubation but recovered fully with supportive care. We report the clinical details of these cases as well as a review of lidocaine toxicity.

Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
Local Anesthetics: Common Agents and Their Applications
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...
