Prolonged Pulseless Electrical Activity Cardiac Arrest After Intranasal Injection of Lidocaine With Epinephrine: A Case Report

Local anesthetic toxicity is a rare but serious complication of local anesthetic administration. Although lidocaine has a safety profile superior to other amide local anesthetics, we report a case of cardiac arrest after intranasal injection of lidocaine. The case involves a 22-year-old healthy woman who experienced pulseless electrical activity shortly after a submucosal injection of 2.2 mg/kg of lidocaine with epinephrine. Resuscitative efforts were unsuccessful until a bolus of intralipid was given. This case emphasizes that even a “low” dose of a less lipophilic drug has the potential for severe toxicity.

It has always been my impression that CRNAs are supervised pretty much everywhere in the US, but I recently did some looking around at the anesthesia staff from a hospital back home and found there is no anesthesiologist (or at least evidence of one) to be found. I'm a 3rd year med student but very interested in anesthesia and I understand that my interests may change. I'm somewhat familiar with pass-thru legislation but the specific word of law in my home state is that "CRNAs may function... "Independent" CRNAs
