EMCrit Podcast 21 – A Bad Sedation Package Leaves your Patient Trapped in a Nightmare

Pushing some ativan followed by vecuronium is no longer an acceptable strategy to manage post-intubation sedation. A good analgesia and sedation package is essential if you care about your patient’s comfort and well-being. We need to move to PAIN-FIRST paradigm. Optimize analgesia and then add in sedative agents as a bonus. In this episode of the EMCrit Podcast, I expand on a previous rant to discuss the optimal way to handle routine post-intubation patients and some special scenarios you may encounter.

The Routine

Here is the Lancet Article I mentioned:

(A protocol of no sedation for critically ill patients receiving mechanical ventilation: a randomised trial)

Post-Intubation patients are in pain b/c they have a piece of rigid plastic jammed down their throats and b/c we do a lot of evil-seeming stuff to them in the ED.

Give them a bolus of fentanyl or morphine as soon as you complete the intubation (or better yet, with your RSI drugs)

Fentanyl Protocol
Morphine Protocol

Only when you have a calm, relaxed, but fully awake patient, add on a touch of sedative for hypnosis, amnesia, and anxiolysis.

Use a sedation scale like RASS.

Special Scenarios

1. Hypotensive Medical Patient-the patient’s blood pressure is never too low to get adequate pain control and sedation. Start them on a pressor and give them comfort. Fentanyl/versed is probably a good combination. Maybe in the future ketamine/versed.

2. Delerium Tremens-these patients need GABA first. My patients have already received 200-400 mg of diazepam before getting intubated so more benzos will probably not help. Use propofol/fentanyl. If propofol is not available, use versed/fentanyl/phenobarbital. Here is a DT protocol that encompasses phenobarb. Also see my DT Podcast.

3. Neurocritically Ill Patients-aka the head bleeds. This one is for Mike, a flight medic. Fentanyl/propofol is the way to go for these patients. Take them deep during the first 24 hours or so. Treat pain and sedation needs first, before add anti-hypertensives; their blood pressure may come down when you treat their pain. If you are transferring these patients, have a very low threshold to intubate, leaving them on propofol/fentanyl. WHen the receiving hospital gets the patient, they can easily extubate them if you used these medications.

Here is my extubation article.

4. Hypotensive Trauma Patients-this pertains to trauma patients hypotensive because of hemorrhagic shock.  I get a bunch of ketamine and a bunch of fentanyl. If their MAP > 65 then I give 25 mcg of fentanyl. Wait a couple of minutes and if still > 65, give some more. If their MAP < 65, I give 10-15 mg of ketamine. Keep going with this until your patient looks good.
