Summary
A neonate developed toxic methaemoglobinaemia after a standard dose of prilocaine local anaesthetic. This case highlights neonates' increased susceptibility to this rare but serious adverse drug reaction.
Area of Science:
- Toxicology
- Pharmacology
- Neonatal Medicine
Background:
- Prilocaine is a local anesthetic used for analgesia.
- Toxic methaemoglobinaemia is a known complication of prilocaine, typically associated with overdose.
- Neonate susceptibility to adverse drug reactions requires careful consideration.
Observation:
- A neonate received a standard dose of prilocaine for facial laceration repair.
- The neonate developed toxic methaemoglobinaemia despite adhering to recommended dosages.
- This presentation is unusual due to the patient's age and the absence of overdose.
Findings:
- Neonate physiology increases susceptibility to methaemoglobinaemia.
- Clinicopathological features of prilocaine-induced methaemoglobinaemia in neonates are presented.
- Diagnostic challenges and treatment options for this condition are discussed.
Implications:
- Clinicians must be aware of the heightened risk of methaemoglobinaemia in neonates, even with standard prilocaine doses.
- This case underscores the need for vigilant monitoring and prompt diagnosis in infants receiving prilocaine.
- Understanding neonatal susceptibility can inform safer anesthetic practices and management strategies.
