“stay and play”
“play and run”
Pre-hospital :Pre-hospital 14.5 million EMS transports annually
Moderate to severe pain in 20%
50% are children

Only 6 papers prehospital pain management (1980-1996)
Challenges and barriers in prehospital setting
Consent
Methodology
Statements :Statements “Relieving discomfort may be the most important task EMS providers perform for majority of their patients.” ACEP 1997
“Relief of discomfort is the most relevant outcomes measure for majority of pre-hospital conditions” EMSOP / NHTSA 1999
In the perfect world… :Assess for circulation and sensation
Check for other injuries
Age appropriate pain assessment 8/10
Screams with attempts to splint
Imagery, start IV, fentanyl
5 minutes later, pain score is 3/10
Arm is splinted with minor discomfort
Gently placed in the rig and slow ride to ED
Reassessment before ED; pain score 2/10 In the perfect world…
Prehospital opioid administration for fractures :Prehospital opioid administration for fractures
Time to first dose of opioid :Time to first dose of opioid Scoop and run result in significant delay in analgesic administration.
Pain Management Barriers :Pain Management Barriers Provider barriers
System barriers
Patient barriers
Survey dataHennes, et al. Prehospital Emerg Care 2005;9:32-39 :Survey dataHennes, et al. Prehospital Emerg Care 2005;9:32-39 Reasons for withholding morphine in children
Inability to assess pain
Patient refusal
Drug seeking behavior
No indications for vascular access
Common assumptions & attitudes :Common assumptions & attitudes There is given amount of pain for given injury
Newborn babies do not feel pain
Children have no memory of pain
Children metabolize opioid differently
Children may become addicted to narcotics
Pain is character building
Use of pain medication is sign of weakness
No pain, no gain
Provider barriersKim et al. 2006 NAEMSP abstract :Provider barriersKim et al. 2006 NAEMSP abstract Doubts the need for pain management
Lack of education
Pain physiology & pharmacology
Difficulty in pain assessment
Lack of easy to use assessment tool for children
Questions the validity and reliability of tools
Negative incentives
Need for an IV & difficult IV
Transport time
Work load
Negative feedback from Docs
System barriers :System barriers Lack of education
Physiology, assessment, pharmacokinetics, outcomes data
Medical control
Reluctant to provide pain meds
Ricard-Hibbon 1999 & Fullerton-Gleason 2002
Multiple tiered system
EMT vs. paramedic
Patient barriers :Patient barriers No pain meds prior to ED (74%) Spedding 1999
harmful
hospital’s responsibility
not available
70% of adults with severe pain did not ask for pain medication Richrd-Hibbon 1999
ED physicians When should EMS provide analgesia? :ED physicians When should EMS provide analgesia? based on the obvious deformity it’s so easy….just get a doctor and get the morphine
Transport time again
What if I have a little finger….put an IV in
depends too on how bad it actually looks
I think if it is obviously deformed they think they should put an IV in
Don’t they have to call the doctor if they have an IV?
ED physiciansIs prehospital pain management a benefit? :ED physiciansIs prehospital pain management a benefit? Yes
Calmer patients
Expedites evaluation
If it is grossly deformed, no problem
No
If short transport time
Unable to evaluate
If they mess up…
ED physicians Focus group summary 2004 :ED physicians Focus group summary 2004 Not aware of pain protocols
Limited experience with prehospital pain management
Pain assessment report is rarely given
It seems easy to OD kids
Evidenced interventions :Evidenced interventions Protocol liberalization Pointer et al. PEC 2005
Online to offline administration of morphine
2.8% to 19% increase in MS administration
Education French et al. PEC 2005
3 hour educational intervention
Pain med use 20.4% to 24.5%
NP intervention 2.5% to 34.7%
Pain scores 44.5% to 95.4%

Reference Case :Reference Case Consider following issues during the presentation
Q1: Why is prehospital pain management important?
Q2: Initial assessment and intervention?
Q3: Best method of pain assessment?
Q4: Indications for pain management?
Q5: What determines the need for pain medications?
Q6: What medications should be considered?
Q7: Dose and route of administration?
Negative Effects of Untreated Pain :Negative Effects of Untreated Pain Interferes with normal bodily function
Increased metabolic rate
Interferes with clotting
Alters immune function
Emotional stress/Suffering
Anxiety (Fear of unknown)
Powerlessness
Loss of control Q1: Why is prehospital pain management important?
Pain results in a stress response :Biochemical: stress hormone release
Epinephrine and norepinephrine
Steroids, growth hormone, and glucagon
Increase metabolic rate
May cause cardiopulmonary instability
Physiologic
Tachycardia, tachypnea, BP elevation
Behavioral
Facial grimace
Physical withdraw, kicking
Crying
The response varies in every patient based on age, development, and prior experience Pain results in a stress response

A landmark publication that called into question the widely held belief that neonates do not have the neurophysiologic apparatus to experience pain
Also decreased stress response and decrease morbidity and mortality after major surgery in neonates.

Validated in children“true representation of pain”
“These faces show how much something can hurt. This face (point to the left-most face) shows no pain. The faces show more and more pain (point left to right) up to this one (point to right –most face) it shows very much pain. Point to the face that show how much you hurt now.” 0 2 4 6 8 10 Q3: Best method of pain assessment?
