Removal of the Long Spine Board From Clinical Practice: A Historical Perspective

Acute and Emergent Spinal Injury Assessment and Treatment

Sports participation is a leading cause of catastrophic cervical spine injury (CSI) in the United States. Appropriate prehospital care for athletes with suspected CSIs should be available at all levels of sport. Planning the process of transport for home venues before the start of the season and ensuring that a medical time out occurs at home and away games can reduce complications of transport decisions on the field of play and expedite transport of the spine-injured athlete.

Factors which affect the application and implementation of a spinal motion restriction protocol by prehospital providers in a low resource setting: A scoping review

·

There is a need for a patient-centred approach to the prehospital spinal management approach, which considers the associated risks, available personnel and limited resources.

·

There is limited evidence supporting the use of the NEXUS and CCR decision tools in the prehospital setting.

·

Prehospital spinal motion restriction decision tools should focus on reducing unnecessary spinal motion restriction and its associated adverse effects

·

Developing a decision tool with more context-specific prehospital instructions for selective spinal motion restriction is of value.

Introduction

The safety and effectiveness of prehospital clinical c-spine clearance or spinal motion restriction (SMR) decision support tools are unclear. The present study aimed to examine the available literature on clinical cervical spine clearance and selective SMR decision support tools to identify possible barriers to implementation, safety, and effectiveness when used by emergency medical service (EMS) practitioners.

Method

We performed a focused scoping review of published literature on the prehospital use of clinical c-spine clearance and SMR decision tools in adult blunt trauma patients. The Medline, Embase, Cochrane Library, Cumulative Index of Nursing and Allied Health Literature, Web of Science, Turning Research into Practice and EBSCOhost online databases were searched (February 2021). The type of decision support tool and facilitators and barriers to its use were extracted from each included publication in accordance with a modified descriptive-analytical framework. Extracted data were subjected to thematic analysis.

Results

Following screening, forty-two articles were included in this scoping review. No studies conducted specifically in low resource settings were found. The majority of articles (57%) evaluated the use of specific SMR decision support tools, such as the National Emergency X-Radiography Utilization Study (NEXUS) and the Canadian C-spine Rule (CCR). Potential facilitators of safe and effective use were identified in 60%, and potential barriers to safe and effective use in 55% of included articles. Only one study evaluated the CCR when used by EMS practitioners, making it difficult to determine its appropriateness for implementation in the prehospital setting.

Conclusion

This is the first scoping review, to our knowledge, that has attempted to identify the possible barriers and facilitators to their implementation, safety, and effectiveness when used by EMS practitioners. Key issues identified included terminology, guideline compliance and implementation, and a lack of context-specific evidence. These may provide important considerations for future guideline development.

Removal of the cervical collar from alpine rescue protocols? A biomechanical non-inferiority trial in real-life mountain conditions

Background

Alpine skiing rescues are challenging because of the mountainous environment and risks of cervical spine motion (CSM) induced during victims’ extrications (EXs) and downhill evacuations (DEs). The benefits of applying a cervical collar (CC) over manual in-line stabilization without CC (MILS) in terms of spinal motion restriction during simulated alpine rescues are undocumented. Our hypothesis was that CSM recorded using MILS alone is non-inferior to CSM recorded with a CC according to a 10 degrees margin.

Methods

A total of 32 alpine extrications and 4 downhill evacuations on different slope conditions were performed using a high fidelity mannequin designed with a motion sensors instrumented cervical spine. The primary outcome was the peak extrication 3D excursion angle (Peak 3D θ_EX,) of the mannequin’s head. The secondary objectives were to describe the time to extrication completion (tEX) and to highlight which extrication manipulation is more likely to induce CSM.

Results

The median Peak 3D θ_EX recorded during flat terrain extrications using CC was 10.77° (95% CI 7.31°–16.45°) compared to 13.06° (95% CI 10.20°–30.36°) using MILS, and 16.09° (95% CI 9.07°–37.43°) for CC versus 16.65° (95% CI 13.80°–23.40°) using MILS on a steep slope. Peak 3D θ_EX with CC or using MILS during extrications were equivalent according to a 10 degrees non-inferiority hypothesis testing (p < 0.05). Time to extrication completion (tEX) was significantly reduced using MILS without CC on a flat terrain with a median duration of 237,3 s (95% CI 197.8 s, 272.2 s) compared to 358.7 s (95% CI 324.1 s, 472.4 s). During downhill evacuations, CSM with and without CC across all terrain conditions were negligible (< 5°). When CC is used; its installation manipulation induces the highest CSM. When EXs are done using MILS without CC, the logroll initiation is the manipulation inducing the highest risk of CSM.

Conclusion

For experienced ski patrollers, the biomechanical benefits of spinal motion restriction provided by CC over MILS during alpine skiing rescues appear to be marginal and CC use negatively affects rescue time.

Extrication techniques of entrapped car crash victims: a scoping review

OBJECTIVE

to summarize the extrication techniques of entrapped car crash victims with potential spinal injury.

METHOD

a literature review study, of scoping review type, using the MEDLINE/PubMed, CINAHL, Scopus, Science Direct, Web of Science, Cochrane Library and gray literature data sources, without time frame, with studies that addressed extricating techniques extrication of entrapped car crash victims.

RESULTS

a total of 33 studies were included that enabled identifying and summarizing the different types of extrication and respective devices for extrication of entrapped car crash victims, indicated according to injury assessment and the victim's clinical condition. All pointed to the need for techniques to maintain neutral alignment and prevent spine twists.

CONCLUSION

this study indicated that injury assessment with an emphasis on the victim's clinical condition provides a coherent decision-making regarding the technique and device to be used. However, carrying out other comparative studies between existing techniques may help in the decision-making process more assertively.
