[Inadvertent intravenous infusion of 380 mg ropivacaine].

This is a report about an inadvertent intravenous infusion of 380 mg ropivacaine in a 84-year-old patient over a period of 1.75 h. The level of serum ropivacaine measured immediately after the end of the infusion as well as 2 h and 7 h later, was initially in the lower toxic range (free concentration of 0.48 micro g/ml). The patient showed no symptoms of intoxication neither clinically nor during the technical examinations (EEG, ECG). This case confirms the wide therapeutic range of ropivacaine.
