Case ReportsEarly intralipid therapy may have prevented bupivacaine-associated cardiac arrest.
Local anesthetic-induced cardiotoxicity remains a complication of regional anesthesia, with the potential to result in cardiac arrest refractory to resuscitation. Successful resuscitation using Intralipid (Baxter Pharmaceuticals by Fresenius Kabi, Uppsala, Sweden), has been reported in 2 patients with bupivacaine-induced cardiac arrest. ⋯ Early treatment with Intralipid may help prevent cardiac arrest and speed successful resuscitation efforts.

Randomized Controlled Trial Comparative StudyEffects of using the posterior or anterior approaches to the lumbar plexus on the minimum effective anesthetic concentration (MEAC) of mepivacaine required to block the femoral nerve: a prospective, randomized, up-and-down study.
To evaluate if psoas compartment block requires a larger concentration of mepivacaine to block the femoral nerve than does an anterior 3-in-1 femoral nerve block. ⋯ Using a posterior psoas compartment approach to the lumbar plexus does not increase the minimum effective anesthetic concentration of mepivacaine required to block the femoral nerve as compared with the anterior 3-in-1 approach, and provides better quality of intraoperative anesthesia due to the more reliable block of the lateral femoral cutaneous and obturator nerves.
