During part of my Casualty Care class we talk about Pain Management and its importance in overall patient care. When the body is in pain several things happen but one of the important items is an increase in heart rate. This is a result of activation of the Sympathetic Nervous System (SNS) which is the same system that activates in Fight, Flight or Freeze. This heart rate increase will occur independent of the pathophysiologic response to the injury that has caused the pain (shock will result in an increased heart rate as a way to compensate for a falling blood pressure).
So why is this important? Controlling pain will help control blood loss in the trauma patient. Control the pain, lower the pulse (SNS activation only), less bleeding will occur. From an overall patient management standpoint, pain management is important for patient comfort as well.
This lesson was reinforced last night when I had severe left side flank pain. I have had kidney stones before, but never with this level of pain. After trying to fight through it for close two hours I finally went to the ED at midnight. I was sweating, nauseated and barely able to walk. My heart rate upon arrival was 140. This rate was pure SNS activation in response to pain as the injury (kidney stones) should not produce an increased heart rate. After some Toradol, Dilaudid and Norco my pain deceased and my heart rate dropped back down into the 70's.
In the absence of a Doc or Medic who can give you some good controlled substances, here are the pain management choices that work well in the trauma patient:
Tylenol
Mobic (Prescription only but you can find and order from Online Canadian sources)
AVOID - ASA, Motrin or other NSAID, they jack up you body's natural ability to clot, something you need in trauma.
Mobic is a NSAID but does not have the same effect on your body's ability to clot. Mobic is one of the simple meds for pain management used by the military.

What life threatening injury can present with flank pain? This is a differential diagnosis. Given the signs and symptoms what could the injury or illness be? In my case last night, peeing blood is a good thing because you can pretty much rule out this life threatening condition.
