Local anesthetic dosing and toxicity of pediatric truncal catheters: a narrative review of published practice
Authors' conclusion
Bolus doses of bupivacaine and ropivacaine frequently comport with expert recommendations. Infusions in patients under 6 months used doses associated with toxicity and toxicity occurred at a rate consistent with single-shot blocks.
