ObjectivesDiscuss current standard of care and

protocols regarding spine injuries.Review research on spine injuries and

evaluation/treatment standards.How to implement spine assessment

protocols into your system.

Spinal Immobilization1960-70’s

EMS standards developedConsensus and Common Sense

Thought to be best practiceNow changing?

MAST Pants, Massive IVF in trauma

Who needs to be immobilized?

Even if they walked away from this?

Spinal ImmobilizationDo we immobilize for:

Mechanism of Injury?

Symptoms and/or Physical findings?

Spinal ImmobilizationLittle research

Never been shown to improve outcomes

Malaysian /New Mexico StudyHauswald, Acad Emerg Med 1998

5 yr retrospective chart review of 2university hospitals

Less neurologic disability inunimmobilized Malaysian patients

Disproves many theories that previouslyjustified widespread spine immobilization

Malaysian /New Mexico StudyC-spine fractures = >2,000-6,000 NL-spine fractures = >4,200 N

Head off the end of stretcher = 40 N

Spinal ImmobilizationBUT - Standard of Care (in U.S.)

One of the most common EMS proceduresMillions of patients immobilized each yearNot necessarily in other parts of the world

Most Current EMS ProtocolsApply spinal immobilization to all

patients with potential for spine injurybased on mechanism of injury

If in doubt - IMMOBILIZE!

The ResearchNo RCT to asses spinal immobilization

on trauma patient mortality, neurologicinjury, spinal stability, or adverse effectssustainedKwan, Cochrane Database 2001/2007 #2803

The ResearchNEXUS

Hoffman, et. al. - NEJM, July 2000

Canadian C-Spine RuleStiell, et. al. - JAMA, Oct 2001

NEXUSMoves to a standard of clinical spine

clearance in emergency departmentsDecreased imaging in 12.6 % (4,309 pts)

N=34,069 patients

NEXUS All 5 criteria met = No Xray

1. No midline cervical tenderness2. No focal neurological defect3. Normal alertness4. No intoxication5. No painful distracting injury

Canadian C-Spine RuleProvides another clinical spine clearance

pathwaySlightly different protocol - more if/then

Age listed as a factor (>65)Mechanism still plays a roleRange of motion of neck final test

Spine clearing protocolsNEXUS, Canadian C-Spine Rule

Xrays or CTs

Little risk to patients or EMS providers

Flight EMSPatient’s cleared in referral ED’s by CT

and board certified EM physicians placedback on boards for transfer to traumacenters.

SummaryNot everyone with blunt trauma needs

spinal immobilization in the ED or in thefield

Selective spinal immobilization can andshould be done by prehospital providers
