Fundamental Disaster Medicine Concepts
Effective response to an MCI involves application of basic and advanced skills and critical clinical decision making with limited resources.
Being able to respond to day-to-day incidents improves (but does not guarantee) your ability to respond to the “big ones”.
Corollary: If you can’t handle the “little ones” effectively, you sure won’t be able to handle the “big ones”. So How Well Do We
Handle the “Little Ones”?

Incorrect Medication Doses, Overdoses and
Underdoses
Conclusion
Medications delivered to children in the prehospital setting by paramedics were frequently administered at doses outside of the proper range when compared with documented patient weights. EMS systems should develop strategies to reduce pediatric medication dosing errors.

Summary of Studies
Hoyle Study: 23% to 100% dosing error rate MI PEEDS Study: 25% to 93% dosing error rate MI EMSIS Study: 62% to 75% dosing error rate
Studies limited to EMS (high performance EMS) Do other health professionals do better?
Implications in Disaster Medicine
Higher than usual level of emotional stress Emergency personnel task overloaded Use of non-emergency personnel for augmentation
e.g., Ortho nurse pulled to ED Need for highly potent meds with significant risks
Analgesics, sedatives, neuromuscular blockers, ACLS meds
Use of alternative, unfamiliar meds Unknown pediatric patient weights
Plan Ahead – Minimizing Risk of Pediatric
Medication Errors People Practice and Practices Protocols Paraphernalia
People Training and Education
Increased use of existing standardized courses (PALS/PEPP) Increased emphasis on safe med administration
More frequent, brief continuing education sessions 60 minutes twice a year vs. 4 hours every 2
years Simulation-based training
High intensity, small group Does not require high-fidelity simulators
Knowledge Assessment
Q. “What is the dose of Benadryl for an 8 kg infant who is in anaphylaxis?”
A. 1 mg/kg IM or IV
Performance-Based
Assessment
Q. “This simulated infant is in anaphylaxis and has received epinephrine. An IV line is in place. Give another drug.”
Performance-Based
AssessmentAnswer:
1. Recall “Benadryl.” 2. Recall or look up the dose: 1
mg/kg IV.3. Calculate the dose in mgs:
1 mg/kg x 8 kg = 8 mg
4. Find the concentration on the bottle.
5. Convert a weight dose to a volume dose. 8 mg
50 mg/mL
= 0.16 mL
6. Draw 0.16 mL out of the vial with a 1 mL syringe.
7. Find the closest port on the IV line.8. Attach the syringe without contaminating the line.
9. Clamp the line upstream.10. Deliver the entire volume.
Practice and Practices Practice (Exercising)
Include peds in EMS and hospital exercises Require simulated med administration Use wireless ped simulators
Practices Mandatory buddy-check for all pediatric med
administration Requires culture change Challenges with single paramedic crews
No fault med error reporting systems Provide info on near misses/hits >>>> Safety solutions
Protocols
Greatly simplify dosing protocols Avoid non-whole numbers Broad, simple doses
Epi-Pen vs. Epi-Pen Jr. Use single doses when appropriate
Glucagon IM for hypoglycemia Can this be done safely?
~.4 mg/kg
RAMPART Study
Rapid Anticonvulsant Medications Prior to Arrival Trial
New England Journal of Medicine Silbergliet, et al Feb 16, 2012
Multi-Center Randomized Trial Including Detroit EMS Compare
Midazolam 10 mg IM (13-40 kg 5 mg IM)
Lorazepam 4 mg IV (13-40 kg 2 mg IV)
RAMPART Findings
Conclusion: For subjects in status epilepticus, intramuscular midazolam is at least as safe and effective as intravenous lorazepam for prehospital seizure cessation.

Summary
Caring for critically ill and injured kids is extremely stressful Disasters greatly increase stress
Pediatric medication errors are common During a disaster med errors could significantly increase
There are many ways to potentially reduce ped med errors By reducing pediatric medication errors on a “routine”
basis, we will provide safer, more effective care in a disaster
