EMCrit Podcast 29 – Procedural Sedation, Part II

It seems the government and other specialties are trying hard to make sedation as difficult as possible in the ED. We must persevere to provide the best procedural sedation to allow maximal comfort and safety for our patients. This continues the discussion started in Part I, where we discussed etomidate, ketamine, and versed/fentanyl. In this podcast, I discuss propofol, ketofol, and dexmedetomidine.

the emcrit procedural sedation chapter has tons of references for all of this


great propofol articles:

Ann Emerg Med 2008;52:392-398
Ann Emerg Med. 2007;50:182-187

Start with fentanyl 1-1.5 mcg/kg

Then give propofol 0.5-1 mg/kg

may need additional injections of 0.5 mg/kg

When patient is where you want them, begin the procedure

May need to give additional 20-30 mgs if the patient becomes too light

Burns on injection, you can precede with 20-40 mg of lidocaine to numb the vessels

1:1 mix of ketamine and propofol

In 20 ml syringe, place 10 ml of propofol (10 mg/ml)

And 10 ml of ketamine at a concentration of 10 mg/ml

Note: your ketamine may come in a different concentration, if so dilute down to 10 ml of 10 mg/ml

Shake like a martini


Precede with fentanyl 1 mcg/kg

Start with 0.5-1 mcg/kg over 10 minutes for loading dose

then use an infusion 0f 0.2-1 mcg/kg/hr

Beware in the bradycardic, hypotensive or patients with heart blocks

May need to supplement with 1-2 mg of midazolam

Procedural Sedation – Part I

It seems the government and other specialties are trying hard to make sedation as difficult as possible in the ED. We must persevere to provide the best procedural sedation for the maximal comfort and safety for our patients. This brief lecture was originally posted on the defunct EMCrit Lecture Site on 8/7/2009.

I’m reposting it here so I can post part II sometime this week.

This episode, Part I, covers general concepts on sedation as well as ketamine and etomidate/fentanyl.

Part II will cover propofol, ketofol, and dexmedetomidine.

Part III, to be done some time in the future, will cover really difficult sedations.

My friend Reub Strayer has a great PSA checklist as well





EMCrit Podcast 19 – Non-Invasive Ventilation

Intubation is a sexy procedure, there is no doubt about it.

NIV does not have the glamour; it’s not nearly as cinematic. But for the patient, to spend 30 minutes on a NIV mask is preferable to a couple of days on the ventilator. In this episode, I discuss some of the basic ideas and methods of NIV.

It is pretty simple as the mode only has 3 main settings:

FiO2 – set based on oxygen requirements, just like on the vent

PEEP/EPAP/CPAP – all the same thing, set this based on OXYGENATION needs. If the patient’s sat is low, start at 5 cm H20 and titrate up to 15-17 as needed.

PSV/IPAP – this setting is for ventilation. If your patient does not have ventilation problems, they don’t need PSV. If they do, start at 5 cm H20 and titrate to 15-17.

Yes, that’s right, I did not tell you to put every patient at 10/5. Very few of your patients will have both ventilatory and oxygenation problems. Asthma and COPD need inspiratory support. APE, atelectasis, pneumonia patients need PEEP.

I also talk about sedation while a patient is on NIV.


EMCrit Podcast 18 – The Infamous Awake Intubation Video

This post marks the return of the Awake Intubation Video. If you’ve seen it, we will have a brand new post early next week. If you haven’t, well you are in for a treat:

Awake Intubation can save your butt!

It requires forethought and humility–you must be able to say to yourself, “I am not sure I will be able to successfully intubate this patient.” However, the payoff for this thought process is enormous. You can attempt an intubation on a difficult airway with very few downsides. If you get it, you look like a star, if you don’t you have not made the situation worse.

Two of my critical care resident specialists, Raghu Seethala and Xun Zhong, volunteered to intubate each other awake. The purpose of this was to let them gain experience, understand what their patients would feel during the procedure, and to prove that awake intubation can be done without complicated nerve block injections or fragile equipment, such as a bronchoscope.

Here is the procedure for ED Awake Intubation–EMCrit Style:


If you can give it early 10-15 min before topicalizing, it will be most effective.

  • Glycopyrolate: 0.2 mg IVP (No central effects – does not cross BBB. You can use atropine, but more side effects are possible)
  • Suction and then pad mouth dry with gauze – you want the mouth very dry!
  • Adminster Odansetron 4mg IV to blunt the gag-reflex


  • 5 cc of 4% lidocaine nebulized @ 5 liters per min
  • Gargle with viscous lidocaine (4% best, 2% ok). Place a blob (~3 cc) on a tongue depressor, put it in the back of the throat and have the patient gargle and then spit
  • Spray the epiglottis, cords, and trachea with 4% lidocaine (3 cc) in a Mucosal Atomizer Device (MAD). The patient will cough during this spraying, wear eye/face protection
  • Have another syringe loaded with 4% lidocaine to spray with during the procedure

Note: the systemic and pulmonary absorption from this method is quite low. The only place to watch out is spraying the trachea. I would not spray more than 2-3 cc down the ol’ windpipe.

SEDATE (Choose one!)

  • Ketamine and propofol in the same syringe makes Ketofol. The classic mix is 50 mg of ketamine to make 5 cc and 50 mg of propofol to make 5 cc. Put these both in a 10 cc syringe and shake. Depending on the patient’s hemodynamics, I sometimes will use more ketamine (75% instead of 50%). Give 1-2 cc every minute until you have the patient relaxed, but still breathing and arousable.
  • Ketamine alone also works just fine. Start with 20 mg and give 10 mg every minute or so.
  • If you have it, Dexmedetomidine also works very well as long as your patient is not bradycardic.
  • If you have neither of these 2 mg of midazolam will do just fine.
  • Preoxygenate with NRB

  • Optimally position (ear to sternal notch) with the head tilted all the way back

  • Restrain both arms with soft restraints to prevent the “grabbies”

  • Switch to nasal cannula

  • INTUBATE with Fiberoptic laryngoscope and bougie

  • If the patient coughs or is uncomfortable after placing the bougie through the cords, push more med from the ketofol syringe.

  • Thread  the tube over the bougie with the laryngoscope still in the mouth

  • Confirm tube placement

That’s all for this week

EMCrit Podcast 15 – the Severe Asthmatic

Don’t intubate the severe asthmatic,

try NIV first

continue the nebs on the NIV

obviously they need steroids and throw in Mag Update: (3 MG RCT tells us to skip the Magnesium even in severe asthma)

does ketamine work? maybe…

If you intubate, Ron Walls says add lidocaine to your sedative and paralytic

if you put them on the vent make sure your plateau pressure stays below 30 cm H20

or make sure the flow graph shows flow has stopped before the next breath
