It appears that New York City has jumped on board with other in eliminating backboards from their protocols. Here is the link to the announcement: http://thesocialmedic.net/files/2015/08/NYCREM-1-1.pdf When do you think the rest of the country will catch up?
Hello fellow EMTs, paramedics, nurses, docs... I'm making a little poll about the use of backboards in the US! If you are outside the US, please post in this topic to indicate your country I would greatly appreciate to have you vote in each of the 3 questions and of course you can share any idea/opinion on the matter here. Thank you in advance!
I sent the memo to two of the EMS agencies (fire based, as are most around here) where I work. We are attempting to effect a cultural shift for the benefit of our patients. I guess we will see if it takes hold. There is no question that spinal immobilization is painful and anxiety provoking for nearly everyone. Patients often have back pain induced solely by lying on the backboard, pain which resolves not long after removal of the board, but which may prompt imaging in the ED due to pain and tenderness caused not by the presenting injury but by the backboard. We have seen harm in other ways: the demented elderly patient with a ground level fall who becomes more agitated from the pain and restriction of the board, the patient from the MVC with anxiety disorder who panics in the straps, the monstrously obese patient who has the equivalent of another person sitting on their chest and has to fight gravity to breathe. I've summarized below some notes from a presentation I have given on myths in EMS. The bottom line up front is that spinal immobilization on a long backboard has no evidence to support its use, but substantial evidence of harm. It is predicated entirely upon theories of injury that have never been shown. It has been taught dogmatically to EMS providers, nurses, and physicians for 3 decades, though there is now a swell of thought that we should modify the practice. Using a long backboard makes sense when pulling an injured person out of the water, or moving them out of a smashed vehicle, but once on the ambulance stretcher, movement is minimal, even with jarring movements of the ambulance. Being on a hard, slippy surface of a backboard will worsen that movement rather than improve it. The National Association of EMS Physicians is working with the American College of Surgeons on a position paper regarding backboarding. The gist of it is that we should eliminate backboards for anything but extrication. There's a few things I've discovered in the literature: Backboards do a horrible job of immobilizing the spine, and movement is worse on the backboard than on a soft surface that conforms to the patient. Patients who can follow commands can typically maintain stabilization of their own spine without assistance. Backboarding increases mortality in certain trauma patients. Backboarding does nothing to prevent neurological sequelae from spinal injury. Backboarding restricts respiration, which some patients cannot tolerate. Backboarding rapidly leads to skin breakdown and pressure ulcers, even after a short period of time, and is particularly hard on the elderly. I think there are some steps we can take to eliminate some pain and suffering and reduce some unnecessary imaging. Stop transporting patients to the hospital on backboards. Utilize the long spine board only for extrication purposes. Once the patient is extricated, using log roll or lift-and-slide technique, lay the patient flat on the stretcher and leave the c-collar in place. Do not ever immobilize a patient with penetrating trauma such as a gunshot wound or stab wound. Immobilization DOUBLES the mortality rate of these patients. Even with neurologic deficits caused by transection of the spinal cord, the damage is done; additional movement will not worsen an already catastrophic injury. Emphasis should be on airway and breathing management and rapid transport to a trauma center. If patient is being intubated, and manual cervical stabilization is hampering this effort, the neck should be moved to allow securing the airway. An unsecured airway is a far greater danger to the patient than a spinal fracture. Eliminate the "standing take-down" for backboarding patients who are ambulatory after an injury. Place a collar and allow the patient to sit on the cot, then lie flat. Patients who are ambulatory and able to follow commands do a better job of preventing movement of an injured spine than rescuers do. Selectively immobilize (with a cervical collar) only those patients at high risk for spinal injury or with clinical indications of spinal injury. Remove cervical collars on conscious patients that tolerate them poorly due to dementia, anxiety, or shortness of breath. Leaving the collar on and fighting them will encourage more spinal movement rather than less. Clear patients from any spinal immobilization clinically utilizing the spinal clearance protocol. This protocol indicates those patients who may require immobilization: High risk injury (high speed MVC, axial loading injury), focal neurological deficits such as paralysis, intoxication, age <65, and presence of midline bony tenderness of the spine. Patients without these findings may be transported without spinal immobilization. Patients who are markedly agitated and confused from head injury may not be able to follow commands with regard to minimizing spinal movement, and combativeness may also be a factor. These patients should remain on a backboard if the crew deems it safer for the patient, and this will be at the discretion of the crew. The above measures will reduce pain and suffering, reduce complications, decrease on scene times, reduce injuries to crews who are attempting to carry immobilized patients, and reduce unnecessary imaging costs and radiation exposure. There is no doubt that our crews will get some push back from the staff at the hospitals. Nurses or physicians may rebuke them for having the patient off the backboard. FD crews should be reassured that hospital staff does not determine their treatment protocols or operational policy, and that any questions can be directed to command staff or to me or to the hospital EMS coordinators.

Motion of a cadaver model of cervical injury during endotracheal intubation with a Bullard laryngoscope or a Macintosh blade with and without in-line stabilization. Turner CR, Block J, Shanks A, Morris M, Lodhia KR, Gujar SK. Source Department of Anesthesiology, University of Michigan, Ann Arbor, Michigan, USA. email@example.com Abstract BACKGROUND: Endotracheal intubation in patients with potential cervical injury is a common dilemma in trauma. Although direct laryngoscopy (DL) with manual in-line stabilization (MILS) is a standard technique there is little data on the effect of MILS on cervical motion. Likewise there is little data available regarding alternative airway techniques in this setting. This study compared intubations with and without MILS in a cadaver model ofcervical instability. We also used this model to compare intubations using DL with a Macintosh blade versus a Bullard laryngoscope (BL). METHODS: Complete C4-C5 disarticulations were surgically created in 10 fresh human cadavers. The cadavers were then intubated in a random order with either BL or DL with and without MILS. The motion at the unstable interspace was measured for subluxation, angulation, and distraction. RESULTS: MILS did not significantly affect maximal motion of this model in any of the three measures using either DL or BL. There were no clinically significant differences in maximal median motion in any of the three measures when comparing the two blades. However, there was significantly more variance in the subluxation caused by DL than by BL. CONCLUSIONS: We were unable to demonstrate any significant effect of MILS on the motion of an unstable cervical spine in this cadaver model. The BL appears to be a viable alternative to DL in the setting of an unstable lower cervical spine. Ann Emerg Med. 2007 Sep;50(3):236-45. Epub 2007 Mar 6. Manual in-line stabilization for acute airway management of suspected cervical spine injury: historical review and current questions. Manoach S, Paladino L. Source Department of Emergency Medicine, State University of New York-Downstate and Kings County Hospital Center, Brooklyn, NY 11203, USA. firstname.lastname@example.org Abstract Direct laryngoscopy with manual in-line stabilization is standard of care for acute trauma patients with suspected cervical spine injury. Ethical and methodologic constraints preclude controlled trials of manual in-line stabilization, and recent work questions its effectiveness. We searched MEDLINE, Index Medicus, Web of Knowledge, the Cochrane Database, and article reference lists. According to this search, we present an ancestral review tracing the origins of manual in-line stabilization and an analysis of subsequent studies evaluating the risks and benefits of the procedure. Allmanual in-line stabilization data came from trials of uninjured patients, cadaveric models, and case series. The procedure was adopted because of reasonable inference from the benefits of stabilization during general care of spine-injured patients, weak empirical data, and expert opinion. More recent data indicate that direct laryngoscopy and intubation are unlikely to cause clinically significant movement and that manual in-line stabilizationmay not immobilize injured segments. In addition, manual in-line stabilization degrades laryngoscopic view, which may cause hypoxia and worsen outcomes in traumatic brain injury. Patients intubated in the emergency department with suspected cervical spine injury often have traumatic brain injury, but the incidence of unstable cervical lesions in this group is low. The limited available evidence suggests that allowing some flexion or extension of the head is unlikely to cause secondary injury and may facilitate prompt intubation in difficult cases. Despite the presumed safety and efficacy of direct laryngoscopy with manual in-line stabilization, alternative techniques that do not require direct visualization warrant investigation. Promising techniques include intubation through supraglottic airways, along with video laryngoscopes, optical stylets, and other imaging devices.
