Tachycardia and convulsions induced by accidental intravascular ropivacaine injection during sciatic block
Ropivacaine, a recently introduced local anesthetic of the amide family ( 1), seems to show less toxicity than bupivacaine (2–4). Nevertheless, both neurologic and cardiovascular toxicities are possible. Six cases of ropivacaine-induced convulsions have previously been reported (5–10), of which three cases also showed cardiovascular toxicity. In three cases, total plasma concentrations were measured ( Table 1).
