Fairly early into an overnight shift the radio goes off.  EMS is approximately 6min out with mid 30s male undergoing CPR. Per bystanders, the patient was going running from door to door, banging on doors and yelling for help. Shortly after being taken into police custody he was found to be pulseless. Had been undergoing CPR approx 10 min. King airway in place. No improvement with dextrose and naloxone.

The intern on and myself go to Room 9 to get set up. When EMS arrives about 10 minutes later, CPR is still ongoing and rhythm has been asytole/PEA throughout. The story remains consistent with him going from door to door yelling for help but now there is some variation as to whether he was cuffed and then lost his pulse, was found without a pulse, or if he got into a physical altercation with the neighbor and then lost pulse shortly after arrest. There are no signs of trauma and we elected to not invite additional chaos by calling a Level 1.

CPR is continued. King airway switched out for ETT. Accucheck 250’s. Central venous access and bilateral chest tubes placed with no rush of air or blood. Sats persist at 85% on vent, etco2 is in 60’s. He gets epi q3m. A dose of vasopressin and steroids. Istat has K 5.5. Lactate >20. Received 2-3 amps of bicarb. Received calcium. Upon rhythm checks he was primarily asystole except for 2-3 checks with a narrow pea that would not persist. Each time the ultrasound was placed on his heart there was no cardiac activity. My thought process at this time was that he was either excited delirium that I’m not going to be able to do much about or some kind of ingestion/overdose. We called pharmacy and asked for lipid emulsion. His ETCO2 had remained between 40-60 and we were about 40 minutes out from reported time of arrest. I decided if the lipids were unsuccessful that would be when we would call it.

They arrived about 15 minutes later and were infused. By now his etco2 had drifted down to 10 on the most recent pulse check. No changes occurred and TOD was called.
