Today, an update on Push-Dose Pressors. I coined the name Push-Dose Pressors (PDPs) way back on episode 6. The idea was not new, anesthesiologists and resus docs have been using bolus-dose vasopressors for decades. I just thought the name was dumb, these are not boluses in the way I have always thought of them (a brief iv drip). I also thought it was crazy that the concept had not really penetrated very far into emergency medicine and the ICU–at least in the States. My prehospital doc friends told me it was common in their world. Since the podcast, I have received 100s of emails describing the use of PDPs to lifesaving effect (or at least code-preventing), but there has been scant published literature on this technique in EM. Recently that has all changed.
Can We Wait for the Drip?
Resus-Ready EDs should be able to get a vasopressor drip up within 8 minutes (completely made-up number, just like most hospital certification standards)
Dead Space in the Lines
What should you do when you can't wait that long?
How do you treat critically low perfusion to the heart & brain?
Push-Dose Pressors Fill the Gap
Especially in the Peri-Intubation, when patients have an annoying habit of popping into cardiac arrest
ED Pharmacists Discussion of Medication Safety for Push-Dose Pressors
While there seems to be a slightly negative bias against docs' capability to mix drugs and a pro-pharmD bias (understandable), the messages from this article as a whole were fantastic. Here are some alterations/things to be aware of that I discuss in the podcast:
- The Prohibition against Pre-Filled Saline Syringes
- The Phenylephrine Chart

I do not recommend the dirty epi drip. Please, please understand how this makes our specialty look
For the love of all this is Resus, Label the frackin bag!

Push-Dose Norepi if you Just Never Want to Deal with Mixing
Check your premixed concentration: If you have the 4mg in 250 ml (16 mcg/ml) you can give 0.5 to 1 ml per minute

Love having ED PharmDs as part of the team! Are there downsides?
