Introduction to Extrication
The Patient Handling / Vehicle Extrication Module
EXTRICATION
Defined - The act of removing a wreck from a victim
Vehicle Non-vehicle
Terms
A,B,C, Posts Safety Glass Tempered glass Laminated glass Uni-body Crumple Zone
cribbing dash roll-up roof flap Nader bolt hand tools powered hydraulics
Basic Principles of Extrication
Patient care precedes mechanical aspects
Patients should be packaged and moved carefully
C-Spine Injuries should be suspected Load and Go patients require Rapid
Extrication
The Golden Hour
The Role of the EMT
Administer patient care Assure that patient is packaged Not allow extrication efforts to endanger
patient If rescue crews are not present -
Extricate Victim
Incident Resource Management
Requires integration of EMS, Rescue, Police, Fire and other services
Command should be established early Should ensure proper utilization of
resources Goal of reducing On Scene Time
Stages of Extrication
Scene survey Vehicle Stabilization Gaining access Life-threatening emergencies Disentanglement Preparation for removal Removal
Initial Unit
Size-up scene Set up official incident command Direct scene survey Establish an action circle Begin to gain access
Scene Size-up and Scene Safety
Mechanics of the accident Number of patients involved Need for additional resources Look for obvious hazards Secure the scene for safety prior to
approaching patients
Hazards
Airbags• deployed• intact
Loaded Bumpers Downed Power Lines Unstable Vehicle Smokers Fuel Spills
HAZARDS - AIRBAGS
Various activation mechanisms Found on Drivers side of most new vehicles Found on Passenger side of some vehicles Are used as side impact protection on some
vehicles Deploys in 1/20 of a second Deploys at a speed of approx. 200mph
Airbag update
New models have airbags in the shoulder harness.
Some new models have airbags in the backs of the front seats to protect back passengers
Passenger side airbag speed can reach 300+ mph
Airbag update
Passenger side airbags have been redirected upward
New cars have a logic control sensor to activate airbags
Can cause injuries and even death Controllers are the ”little black box”
Hazards - Alternative Fuels
LP gas Diesel Fuel Electric Vehicles
Outer circle survey
10- 15 feet around perimeter of vehicle Clear debris / other hazards from area Look around, under, toward and away
from vehicle Check and account for any other
patients Report findings to I.C.
Inner circle survey
Check doors Watch for “loaded” bumpers Determine actual count of patients Note type of vehicle stabilization
needed Formulate access plan
Establish an action circle
1O-15 feet around the vehicle Area should remain free of tools,
equipment, stretchers and unnecessary personnel
Establish a tool staging area Set up sectors and sector commanders
Gaining Entry
protect self stabilize select route• doors• windows• roof– flap – removal
Disentanglement
Break out all glass Open doors • try handles• cut panel• use power tools
remove door Move seats back Remove roof
displace pedals Dash Roll - Up displace steering
wheel
Breaking Glass
Select window away from the patients Rear window is preferred to be broken
first Roll down all other windows, leave 2-3
inches showing Cover with blanket, then break YELL “ BREAKING GLASS”
Dash Roll-up
Cut a bottom of both “A” posts Leave rear doors intact unless
absolutely necessary Crease front fenders Open or Bend (Both Sides) Hood
Dash Roll 1992 Hyundai Excel
Removal
Maintain c-spine control
Look for MOI Treat injuries lmmobilize spine • KED• Long backboard • Other devices
Move patient, not device
Evaluate need for personnel
Choose path of least resistance
Watch for Hazards
LOAD & GO CRITERIA
Altered Mental Status Respiratory Compromise Cardiac Arrest Pelvic fractures ( with signs of shock ) Bilateral Femur Fractures Shock or signs of shock
What is a Car ?
Folded metal, glass, and plastic on wheels
Types of Cars
Conventional Frame unibody composite construction IT’S NOT HOW THE CAR IS MADE , IT’S NOT HOW THE CAR IS MADE ,
BUT RATHER WHAT PEOPLE DO TO BUT RATHER WHAT PEOPLE DO TO THEM THAT MAKES THEM UNSAFE THEM THAT MAKES THEM UNSAFE FOR US TO WORK ON.FOR US TO WORK ON.
Types of Cars
Strength of a car is in its shape
Arches , columns , rolls , creases and layers all add to the strength of a car.
Side door beams make it stronger
A car is strongest end to end
Other Vehicles
Trucks Vans Buses Trains Airplanes
Other Vehicles (Buses)
Built on a frame Body slides on frame Seats support the
sides Entry through the
floor not an option Many types of buses Driver is expendable
Basic hand tools
Cribbing pry axe Hacksaw Screw drivers Linoleum knife Come-a-long Center punch Panel cutter
Hand jack Wonder bar Air chisel Reciprocating saw Hand hydraulics Rope Duct tape chain
Powered Tools (Hi-Tech)
Hurst Tool (Jaws of Life) P-16 Power hawk Life Shear Cutter Band Saw Exothermic Torch Excalibur
