Even when we can't cure a patient, we can relieve suffering. On average, we kind of stink at pain control in the ED. One physician, Dr. Ed Gentile, has created a simple path to optimal acute pain control in the ED. I heard this lecture on the EM:RAP podcast and got permission from Drs. Gentile and Herbert to repost it here. This is not a critical care topic per se, but it is applicable to the critically ill, the non-critically ill–basically any patient who is in pain in the ED.

Patient Controlled Analgesia without the Pump

by Ed Gentile, MD

Need for an effective and efficient process is self evident .

Acute pain protocol for moderate/severe pain

• Administer morphine 0.1 mg/kg IVP (If pt is > 55 y/o, substitute morphine 0.05 mg/kg IVP for this 1st dose)
  + diphenhydramine 0.5 mg/kg IVP
• 7 minutes later the patient is asked, “Would you like more pain medicine?”
• If the answer is yes, give a 2nd dose of morphine 0.05 mg/kg IVP
• 7 minutes later, the patient is asked again, “Would you like more pain medicine?”
• If the answer is yes, give a 3rd dose of morphine 0.05 mg/kg IVP
• This continues every 7 minutes until the patient answers “no” to the question or the patient is asleep.

According to Dr. Gentile, “We don't want to use the minimum, but the optimum pain dose for all patients.”

The protocol uses morphine because it has the longest half-life .

Diphenhydramine prevents antihistamine effects: nausea, vomiting, hypotension.

The protocol is unbiased and controlled by the patient!

Update:

There finally is a study validating this process:
