Ropivacaine Plasma Concentrations after 192-Hour High Dose Epidural Ropivacaine Infusion in a Pediatric Patient without Side Effects

Abstract EN

This case report discusses continuous epidural administration of ropivacaine 0.56 mg kg−1 h −1 for 8 days in a 7-year-old trauma patient to prevent pain, after performing a lower right and upper left leg guillotine amputation.

Venous sampling after 8 days revealed bound and unbound ropivacaine concentrations of 1.1 mg/l and 0.06 mg/l in plasma, respectively.

Arterial sampling for bound and unbound ropivacaine was 1.2 mg/l and 0.05 mg/l in plasma, respectively.

In this case report, long-term high dose epidural infiltration of ropivacaine did not result in severe side effects or complications.

Further studies are needed to explore safety of these concentrations in larger populations of children.
