Bulger E.M., Copass M.K., Sabath D.R., Maier R.V., and Jurkovich G.J. The rationale behind this study was that the optimal testing conditions seen in other studies do not offer a realistic representation in the emergency clinical setting (Bell et al, 2009). A lack of awareness and non-explicit documentation of removal could account for this, further decreasing the validity of the study (Oosterwold et al (2016). Fears of worsening a spinal injury, fears of missing a spinal injury and fears of litigation have long driven this process instead of scientific evidence. On history and physical, the patient may be complaining of sensation changes, neck, and back pain. However, there was enough of a groundswell support to effect change. It is assumed that pressure causing severe pain results in distress, necessitating movement to relieve pain, so high pain scores resulting from pressure potentially impede the main purpose of the cervical collar (Ham et al, 2016).

The OPALS Major Trauma Study: impact of advanced life-support on survival and morbidity. While immobilisation is essential in preventing secondary injury (Houghton and Driscoll, 1999), it is debated whether cervical collars achieve this. . Stawicki S.P., Holmes J.H., Kallan M.J., and Nance M.L. In one large, multi-center study, missed CSI presenting with a neurological deficit occurred in less than 1 of 500 spine injury cases and 1 of 4000 trauma cases, with an average delay in diagnosis of approximately 20 days.86 On one hand, there are studies where up to 8% of necks were not immobilized, seemingly without clinical consequences or progress to neurological deficits.8791 Conversely, Gerrelts and colleagues identified the development of temporary neurological symptoms before treatment, but were unable to identify permanent complications in those with missed cervical fractures.92 Davis and colleagues and Platzer and colleagues reported that delayed diagnosis, in fact, resulted in permanent, severe deficits: Davis and colleagues reported 32,117 trauma patients, 740 cervical injuries, 34 injuries missed, 10 developed permanent deficits,17 whereas Platzer and colleagues reported 367 cervical injuries, 18 injuries missed, 8 developed neurological symptoms, and 2 permanent deficits.93, Considerable force is required to fracture the spine, and subsequent low-energy movements are thus unlikely to cause secondary SCI.94 Plumb and Morris recently proposed that we should simply stop using collars in obtunded patients, because it is likely that minor degrees of cervical spine movement are without consequence and more significant movement prevented by common sense.95 Moreover, awake patients generally maintain a stable neck position with muscle contractions that protect the spinal cord.94 Additionally, and contrary to common belief, most spinal injuries are biomechanically stable in the acute phase, and unstable injuries that have not caused acute, irrevocable injuries are very rare.96 Conclusively, given that collars are ineffective in motion control, we are apt to conclude that the risks of inadequate immobilization may be substantially overemphasized.13,97, It has been conservatively estimated that at least 50100 patients have their neck immobilized for every patient that has a significant CSI.12 This ratio implies that cervical immobilization, usually involving a collar, must be safe and effective to provide a reasonable cost-benefit relationship.

While grade 1 PUs are reversible, there is a risk they can become more severe (NPUAP et al, 2014), making prevention vital. There has never been any evidence that suggests that the C-collar benefits our patients in any way. Goldberg W., Mueller C., Panacek E., Tigges S., Hoffman J.R., and Mower W.R.; NEXUS Group (2001). 2022 Oct 1. doi: 10.1007/s00586-022-07405-6. Scoop-type stretchers and basket stretchers are excellent devices for moving patients, especially over uneven or rough terrain. Some have now replaced the rigid C-collars with a soft foam C-collar as the only device for spinal immobilization. Specific objectives To describe the effects of immobilizing a multiple trauma patient when the spine is unstable. Gunning M., O'Loughlin E., Fletcher M., Crilly J., Hooper M., and Ellis D.Y. Being placed on a hard backboard also causes discomfort. Theyve replaced these with various strategies that minimize backboard use. Gerrelts B.D., Petersen E.U., Mabry J., and Petersen S.R. Increased risk of death with cervical spine immobilisation in penetrating cervical trauma. As with previous studies, a repeated-measures design was used, with a correctly sized collar applied, as well as one size too big and one size too small. Br J Anaesth. 7 however, class ii evidence suggests that patients with penetrating trauma who had prehospital spinal immobilisation have a worse outcome. Management of isolated fractures of the axis in adults. The surgeon : journal of the Royal Colleges of Surgeons of Edinburgh and Ireland, Scandinavian journal of trauma, resuscitation and emergency medicine, In this commentary we argue that fully alert, stable and co-operative trauma patients do not require the application of a semi-rigid cervical collar, even if they are suspected of underlying cervical. It was always thought and taught that additional movement of the spine in a patient with a spinal injury would actually worsen the condition or result in a secondary injury. Statistically, the difference in ROM with the collar was significantly lower than with no collar (P<0.005). Spinal cord injury and direct laryngoscopythe legend lives on. Emergency neurological life support: traumatic spine injury. The ground-breaking approach is only currently in place in three other countries - Australia, Norway and Denmark. (1999). Is this practice effective?Cervical Immobilization C-collars can cause increased diagnostic imaging: EMS and hospital-based care are becoming more integrated. (2009). There are a couple of reasons for this. Miller C.P., Bible J.E., Jegede K.A., Whang P.G., and Grauer J.N. 7. The decrease in ICP values after collar removal reached statistical significance (WMD = - 2.99; 95%CI - 5.45, - 0.52; P = 0.02), meaning an overall ICP decrease of approximately 3 mmHg after collar removal. The cervical collar has been routinely used for trauma patients for more than 30 years and is a hallmark of state-of-the-art prehospital trauma care. (2010). (1989). Effect of manual in-line stabilization of the cervical spine in adults on the rate of difficult orotracheal intubation by direct laryngoscopy: a randomized controlled trial, Dysphagia caused by a hard cervical collar. Given that cervical collars do not provide any significantly increased additional immobilisation and the adverse effects of a cervical collar can be detrimental to patients, the UK Ambulance Service guidelines need to be re-examined in light of the evidence presented within this review and, specifically, removing cervical collars from prehospital practice should be considered.

Thus, arterial blood flowing into the cranial vault continues unimpeded while venous outflow is restricted. However, the existing evidence for this practice is limited: Randomized, controlled trials are largely missing, and there are uncertain effects on mortality, neurological injury, and spinal stability. . However, for those with a reduced level of consciousness and who are unable to protect their own cervical spine, immobilisation is an appropriate level of protection (Benger and Blackham, 2009). One way of doing this could be to incorporate knowledge from extensive epidemiological surveillance studies, such as a recent European multi-center study including more than 250,000 patients, which, by multivariate analysis, tried to identify various risk factors of CSI in trauma patients.22 Efforts should also be concentrated on developing new devices that are more easy, safe, and effective to use.85,220. (2002). This critical review discusses the pros and cons of collar use in trauma patients and proposes a safe, effective strategy for prehospital spinal immobilization that does not include routine use of collars. The impact of prehospital endotracheal intubation on outcome in moderate to severe traumatic brain injury. 6. Effect of prehospital advanced life support on outcomes of major trauma patients.

Bookshelf (2009). 1. This was first reported in a patient undergoing diagnostic imaging and was later studied using unembalmed cadavers where rigid C-collar application resulted in a 7.3 mm 4.0 mm of separation between C1 and C2.27 In high C-spine injuries, rigid collars can actually worsen the patients condition. The effectiveness of extrication collars tested during the execution of spine-board transfer techniques.

Anesthesiologists and anesthetists in nearly every type of hospital setting will eventually be exposed to the multiply injured child. These patients should not be fitted with a collar, but immobilized on spine boards with head blocks and straps. Out-of-hospital spinal immobilization: its effect on neurologic injury. 5. Vincent-Lambert and Mottershaw (2018) substantiate that lengthy on-scene times need to be addressed, and conclude that prolonged on-scene time could negatively affect patient outcome. Patel J.C., Tepas J.J., Mollitt D.L., and Pieper P. (2001). Clearance of the asymptomatic cervical spine: a meta-analysis. 3 however, the evidence behind this practice originated from expert and consensus opinion after minimal studies performed in hospital-based We, therefore, contextualised the findings from facility-based studies' to the prehospital setting. Spine immobilization in penetrating trauma: More harm than good? This raises the discussion of the range of movement when a cervical collar is in place. Routine use of backboards during conveyance of patients with suspected SCIan outdated practicecould distort the conclusions and relevance to practice, lessening the strength of the study. 17. Stone M.B., Tubridy C.M., and Curran R. (2010). (2010). Based on the results and taking into account further data from the current scientific literature, the following conclusions can be drawn: . JAMA. Theyre not tight enough to restrict arterial inflow through the carotid and the vertebral arteries. Even more concerning, there is a growing body . The cervical collar has been routinely used for trauma patients for more than 30 years and is a hallmark of state-of-the-art prehospital trauma care. 25. Furthermore, while the aim of a cervical collar is to restrict movement, Holla (2012) found that it significantly reduced the range of mouth opening, thus compromising the airway, making the use of adjuncts and maintaining a patent airway difficult (Kwan et al, 2001).

Prehospital Trauma Life Support Committee of The National Association of Emergency Medical Technicians in Cooperation with The Committee on Trauma of The American College of Suregons (2010). This was originally published in 2001 as a tool to decide whether or not patients require radiology in the hospital setting.26 In 2011, a revised edition was published for the prehospital setting, but now as a tool to decide whether patients require cervical spine immobilization or not.197, High-quality studies have shown that physicians in the ED can safely use the CCR as well as the NEXUS (National Emergency X-Radiography Utilization Study) criteria to rule out CSI.23,26,198 Studies have also shown that the CCR is more sensitive and specific than the NEXUS criteria, and that using the CCR results in lower rates of radiological examinations.199201 Further, the CCR can be used with similar accuracy and reliability by triage nurses in the ED and paramedics in the prehospital setting.202204, Education of prehospital personnel in clinical clearance of the cervical spine has a large potential for improving management, with an estimated 40% reduction in cervical spine immobilization (and subsequent radiological examinations).43,197, Radiological investigations are often deemed unnecessary for conscious patients without symptoms, neurological deficits, or distracting injuries and that have a full range of motion upon functional examination.205 Evidence also suggests that this straightforward clearance approach can be simplified even further by ignoring distracting injuries,206,207 perhaps except for injuries in the upper chest region.208 Altogether, there is a wide range of algorithms based on different clinical criteria for clearance of the cervical spine in the prehospital setting.8791,205,208218, Patients with reduced consciousness have a higher prevalence of CSIs, and cervical spine clearance in such patients is not as clear cut as in conscious patients.24,27 As a consequence, most patients are fitted with a rigid collar in combination with head blocks and strapped to a spine board during transport, and the collar remains on until they can be evaluated by imaging.1,27,4245 However, based on the information presented so far, we can safely conclude that the presumed benefit of collars is highly questionable, and that there is a large body of evidence on the risks and complications of this practice. An immediate weakness of the studies included were sample sizes; however, it was determined in one study that increasing the number of participants would not affect the outcome as using the best cervical immobiliser can be identified through the ROM it allows.

The current literature review will aim to comprehensively examine research surrounding the adverse effects of cervical collars, and the range of movement they enable, to gain a comprehensive understanding of their efficacy. Holla (2012) concluded that rigid cervical collars did not provide any significant additional immobilisation to head blocks, whereas using a collar could create adverse effects, as discussed.
