Emergency providers are routinely called upon to react to complex scenarios that demand specific life-saving maneuvers, immediately and without warning. The most important impediment to performing well in these situations is your own catecholamines, and the most important catecholamine reduction strategy is preparation. The extent to which you are prepared to immediately react is your usual state of readiness, and it has two parts: cognitive and material. Cognitive readiness requires that you consider emergency scenarios and decide on a plan. This starts with a textbook (by textbook I of course mean the internet) and reading what others think you should do in a given emergency scenario. The hard part of cognitive readiness is keeping up with the endlessly changing, endlessly disagreeing opinions, and deciding how to shape them into a plan that you like and that works for you in your environment. Logistics are key. As medical knowledge expands forever faster, perhaps the most important knowledge of all is knowing what you need to know, and knowing what you can look up. This is not an either/or so much as a spectrum of how close information needs to be to your brain. There are plans that have to live in your brain (management of a completely obstructing airway foreign body), facts that you can take 30 seconds to look up (weight-based dose of atropine), and lists that you can review at your desk (the differential diagnosis of anisocoria). Memory fails when catecholamines are high; planning for emergency scenarios involves the development and deployment of…
This patient suffered a brady-asystolic arrest and a transvenous pacer was placed in the emergency department. We are accustomed to relying on the monitor’s ECG tracing to determine heart rate; however, a good pulse oximeter waveform better reflects the number of perfusing beats. Note the heart rate, as measured by the pulse ox, is reported in purple in the upper-right corner of the monitor. At this point we had achieved electrical capture but not mechanical capture. Watching the pulse oximetry graph is a slick way to guide pacemaker insertion. Cardiac sonography and placing a finger on the patient’s neck to assess the pulse are alternatives.

I take a milligram of crash cart epi, just because it’s the most available and already in a syringe, and put it into a 1 liter bag of NS. Attach to IV and titrate to effect using the knob. If the patient has a full or mostly-full bag of IVNS already hanging, I’ll just grab the crash cart epi and dump it in. Nothing could be faster. 1 mg epinephrine in 1000cc NS = 1 microgram/cc 20 drops/cc therefore 2 drops per second = 6 mcg/min
