A Special K Trip Part 3 – Ketamine for Analgesia & Tranquilization
And now for the conclusion of the 3-part ketamine series with Reuben Strayer. Today’s episode is Part 3 focusing on Ketamine for analgesia and extremely uncontrollable violent patients.
Ready to continue with your Ketamine trip w/Reuben? Here we go!
Ketamine for Analgesia
Who gets ketamine? Chronic pain, poly trauma, oncology pain, etc.
- 0.1-0.3mg/kg have been used.
No pumps for bolus dose? No problem.
- Of course, administering through a pump will always be the gold standard.
How to administer:
- Inject the analgesic dose into NS 100mL and infuse over 15 minutes.
- 15 minutes = 400mL/hr (best!)
- 10 minutes = 600mL/hr (not much difference)
- Why are we diluting the ketamine dose for administration? To prevent psychiatric emergence or your patient from “freaking out.”
- Ketamine drips – always use a pump. (Not everyone will get a drip)
- 0.1mg/kg and titrated every 30 minutes.
- No monitoring required.
- *Use your discretion, if you feel that your pt needs monitoring – put your patient on a monitor and alert your provider.
Some pretty good articles, full list below:
- Sergey Motov’s article on ketamine for pain in the ED
- Cheryl Allen’s article on administering ketamine in Pain Management Journal
- Sergey Motov interviewed on ketamine in EP Monthly
Ketamine for Tranquilization
Who gets it? Your huge guy where you have a small army of security and staff trying to hold him down and you are concerned for the patient’s and staff’s safety.
How often are you using this? Rarely.
- Dissociative Intramuscular (IM) Dose: 4-6mg/kg
- 500mg IM Adult dosing = approx. 100kg person
Monitoring required with airway capable provider at bedside.
Safety Pearl for Violent and Agitated patients (whether you use ketamine or not):
- Don’t attempt to put in an IV line! (If your provider asks, say “No thank you!”)
- Administer IM through the clothing.
- No alcohol swab needed.
- Team approach to hold down patient for patient and staff safety.
