We are always happy to assist you. Nonetheless, cardiac toxicity reappeared 40 min aftercompletion of the lipid emulsion.

In the absence of further lipid emulsion,amiodarone and inotropic support were used to treat cardiotoxicity. This casesuggests that local anesthetic systemic toxicity may recur after initial lipid rescue. Since recurrence of toxicity may necessitate administration of additional doses oflipid emulsion, a sufficient quantity of lipid emulsion should be available whenregional anesthesia is performed. A single injection infraclavicular paracoracoid block wasperformed after placement of an gauge ported IV can-nula.

No sedation was administered. Evoked responses of finger and wrist flexion were firstelicited at 2 mA and disappeared at 0. After injectionof 30 mL of 0. These symptoms prompted immediatecessation of local anesthetic injection and removal of theinsulated needle.

This was immediately followed by gener-alized convulsions and apnea. Convulsions were terminatedwithin 60 s by the administration of IV thiopental, mgsucceeded by cardiotoxicidax further mg. After termination of convulsions, the electrocardiogramtrace became visible and revealed a narrow complex tachy-cardia, which accelerated to a peak rate of bpm. Over90 s, the tachycardia was succeeded by broadening of theQRS complexes, slowing of the heart rate and asystole.

Intralipid mL was administered over approximately90 s, the infusion commencing just prior to asystole. Externalcardiac compressions were begun, tracheal intubation was per-formed and epinephrine 1 mg was administered IV.

Within 3 min of completing the first mL of lipidemulsion, the patient converted from asystole to a narrowcomplex rhythm at bpm. Repeatanalysis 11 min after return of spontaneous circulationrevealed similar values, albeit Pa co 2 had decreased bupivacina 55mm Hg. These measurementsprompted an increase in minute ventilation and IV admin-istration of sodium bicarbonate, insulin, and potassium. Afurther blood bupivscaina analysis min after return of spontane-ous circulation revealed pH 7.

Over the 30 min after return of spontaneous circulation,the remaining mL contained in the Intralipid bag wereinfused. During this time, his heart rate and rhythm revertedto sinus cardotoxicidad at bpm.

The circulation was sup-ported with an epinephrine infusion that was progressivelydecreased to 0. Accepted for publication November 24, Reprints will not be available from the author. Address e-mail toail sun. This was facilitated by administering a 5 mg bolus ofmidazolam and isoflurane end-tidal partial pressure 0.

The debridement was completed within 10 min. After surgery, the patient remained in the operatingroom until intensive care unit admission was possible.

In view of what was presumedto be the recurrence of bupivacaine cardiotoxicity, addi-tional Intralipid was ordered. Admission to the intensive care unit took place 1 h aftercompletion of the amiodarone loading dose by which timethe arrhythmias had terminated and inotropic support wasdiscontinued.

The patient was tracheally extubated 5 h afterhis initial episode of systemic toxicity. Hospital discharge occurred 4 days after the initial event.

We attributed the cardiovascularinstability to recurrence of local anesthetic toxicityafter lipid rescue, a scenario not previously described. The cause of recurrence of toxicity was likely multi-factorial.

The serum concentration of Intralipid wouldhave decreased due to redistribution and metabolism. The elimination half-life of IV bupivacaine is longerthan all other currently used local anesthetics, report-edly 3.

Clinical trials

Bupivacaine may have redistrib-uted back into the central compartment. Initial tissueentry and subsequent acidosis-related ion trapping, 17 with later release into the plasma as the acidosisresolved, would have increased the plasma concentra-tions of bupivacaine.

This bolus may berepeated twice at 5 min intervals if an adequate circu-lation has not been restored. The bolus should befollowed by an infusion of 0. While pancreatitis is aknown complication of chronic hyperlipidemia, 25 thesignificance of the hyperamylasemia seen in our pa-tient is currently unclear. Although we cannot findanother documented increase in amylase or pancreaticinjury after the use of lipid emulsion in resuscitation,this issue must be considered after lipid rescue. In summary, we report a case of recurrent systemiclocal anesthetic toxicity after successful treatment withlipid emulsion.

Because no additional lipid emulsionwas available, the recurrent dysrhythmias were treatedwith amiodarone.
