Field-side and prehospital management of the spine-injured athlete

Overview of Traumatic Brain Injury in American Football Athletes

OBJECTIVE

The aim of this review is to provide a summary of the epidemiology, clinical presentation, pathophysiology, and treatment of traumatic brain injury in collision athletes, particularly those participating in American football.

DATA SOURCES

A literature search was conducted using the PubMed/MEDLINE and Google Scholar databases for publications between 1990 and 2019. The following search phrases were used: "concussion," "professional athletes," "collision athletes," "mild traumatic brain injury," "severe traumatic brain injury," "management of concussion," "management of severe traumatic brain injury," and "chronic traumatic encephalopathy." Publications that did not present epidemiology, clinical presentation, pathophysiology, radiological evaluation, or management were omitted. Classic articles as per senior author recommendations were retrieved through reference review.

RESULTS

The results of the literature review yielded 147 references: 21 articles discussing epidemiology, 16 discussing clinical presentation, 34 discussing etiology and pathophysiology, 10 discussing radiological evaluation, 34 articles for on-field management, and 32 articles for medical and surgical management.

CONCLUSION

Traumatic brain injuries are frequent in professional collision athletes, and more severe injuries can have devastating and lasting consequences. Although sport-related concussions are well studied in professional American football, there is limited literature on the epidemiology and management of severe traumatic brain injuries. This article reviews the epidemiology, as well as the current practices in sideline evaluation, acute management, and surgical treatment of concussions and severe traumatic brain injury in professional collision athletes. Return-to-play decisions should be based on individual patient symptoms and recovery.

Acute Cycling Injuries

The overall activity of cycling, although profoundly heterogenous, often occurs with mechanisms consistent with motor vehicle collisions. Advanced trauma life support is the standard of care. Traumatic brain injury is the leading cause of death, and concussions are common in cyclists. Road rash is the most common injury, and management should be synonymous with other kinds of burns. A unique aspect of cycling medicine is that it often is done on public roadways in close proximity to the athletes during competition. Clinicians who care for cyclists in the field setting should be prepared to manage a broad spectrum of traumatic injuries.

On-Field Management of Suspected Spinal Cord Injury

Acute spinal cord injuries in athletes are rare. However, on-field management of such injuries requires a well-planned approach from a team of well-trained medical staff. Athletes wearing protective gear should be handled with care; a primary survey should be conducted to rule out life-threatening injury while concomitantly immobilizing the spine. Treatment with steroids or hypothermia have not been shown to be beneficial, ultimately time to surgery provides the athlete with the best chance of a good outcome.

Lumbar Spine Injuries in Sports: Review of the Literature and Current Treatment Recommendations

Low back pain is one of the most prevalent complaints of athletes at all levels of competition. The purpose of this literature review is to provide an overview of sport-specific injuries and treatment outcomes that can be used by healthcare providers to better recognize injury patterns and treatment options for different groups of athletes. To our knowledge, no prior comprehensive review of lumbar spine injuries in sports is currently available in the literature, and it is essential that healthcare providers understand the sport-specific injury patterns and treatment guidelines for athletes presenting with low back pain following an athletic injury. Injury mechanisms were found to vary significantly by sport, although some broad recommendations can be made with regards to optimal treatment for these injuries and return to play. Additionally, it was found that certain treatments were more beneficial and resulted in higher rates of return to play depending on the specific sport of the injured athlete. Healthcare providers need to be aware of the different injury patterns seen in specific sports in order to properly evaluate and treat these injuries. Furthermore, an individualized treatment plan needs to be selected in a sport-specific context in order to meet the needs of the athlete in the short and long term.

Acute management of cervical spine trauma

Traumatic cervical spine injuries represent a significant cause of morbidity and mortality in sports. Appropriate management of such injuries is critical to minimizing harm and facilitating optimal long-term recovery and outcome. Management strategies begin with emergency preparedness amongst sideline providers and extends to paramedic services and medical teams in the acute care setting. This chapter outlines the principles of treatment across the care continuum, with a primary focus on hospital-based care. Diagnostic imaging and equipment considerations are reviewed, with discussion of corticosteroid administration, therapeutic hypothermia, and traction of the cervical spine. Approaches to cervical spine stabilization and return to play are also detailed, with an emphasis on patient-centered care and individualized treatment approaches to the athlete.

Cervical Spine Motion during Transfer and Stabilization Techniques

Abstract Objectives. To compare paramedics' ability to minimize cervical spine motion during patient transfer onto a vacuum mattress with two stabilization techniques (head squeeze vs. trap squeeze) and two transfer methods (log roll with one assistant (LR₂) vs. 3 assistants (LR₄)). Methods. We used a crossover design to minimize bias. Each lead paramedic performed 10 LR₂ transfers and 10 LR₄ transfers_. For each of the 10 LR₂ and 10 LR₄ transfers, the lead paramedic stabilized the cervical spine using the head squeeze technique five times and the trap squeeze technique five times. We randomized the order of the stabilization techniques and LR₂/LR₄ across lead paramedics to avoid a practice or fatigue effect with repeated trials. We measured relative cervical spine motion between the head and trunk using inertial measurement units placed on the forehead and sternum. Results. On average, total motion was 3.9° less with three assistants compared to one assistant (p = 0.0002), and 2.8° less with the trap squeeze compared to the head squeeze (p = 0.002). There was no interaction between the transfer method and stabilization technique. When examining specific motions in the six directions, the trap squeeze generally produced less lateral flexion and rotation motion but allowed more extension. Examining within paramedic differences, some paramedics were clearly more proficient with the trap squeeze technique and others were clearly more proficient with the head squeeze technique. Conclusion. Paramedics performing a log roll with three assistants created less motion compared to a log roll with only one assistant, and using the trap squeeze stabilization technique resulted in less motion than the head squeeze technique but the clinical relevance of the magnitude remains unclear. However, large individual differences suggest future paramedic training should incorporate both best evidence practice as well as recognition that there may be individual differences between paramedics.

The effect of laryngoscope handle size on possible endotracheal intubation success in university football, ice hockey, and soccer players

OBJECTIVE

To assess the effectiveness of a standard long-handle laryngoscope and a short-handle laryngoscope on ease of possible intubation in football, ice hockey, and soccer players.

DESIGN

Prospective crossover study.

SETTING

University Sport Medicine Clinic.

PARTICIPANTS

Sixty-two university varsity football (62 males), 45 ice hockey (26 males and 19 females), and 39 soccer players (20 males, 19 females).

INTERVENTIONS

Athletes were assessed for different airway and physical characteristics. Three different physicians then assessed the use of laryngoscopes of different handle sizes in supine athletes who were wearing protective equipment while in-line cervical spine immobilization was maintained.

MAIN OUTCOME MEASURES

The ease of passage of a laryngoscope blade into the posterior oropharynx of a supine athlete was assessed using both a standard long-handle and a short-handle laryngoscope.

RESULTS

Use of a short-handle laryngoscope was easier for all physicians in all sports as compared with a standard-sized laryngoscope. Passage of a laryngoscope blade into the posterior oropharynx of a supine athlete was easiest in soccer players and most difficult in football and ice hockey players for both sizes of laryngoscope. Interference from chest or shoulder pads was a common cause for difficulty in passing the laryngoscope blade into the posterior oropharynx for football and ice hockey players.

CONCLUSIONS

In the rare instances that an endotracheal intubation is to be attempted on an unconscious athlete, a short-handle laryngoscope may provide the best chance for successful intubation.

The assessment of airway maneuvers and interventions in university Canadian football, ice hockey, and soccer players

CONTEXT

Managing an airway in an unconscious athlete is a lifesaving skill that may be made more difficult by the recent changes in protective equipment. Different airway maneuvers and techniques may be required to help ventilate an unconscious athlete who is wearing full protective equipment.

OBJECTIVE

To assess the effectiveness of different airway maneuvers with football, ice hockey, and soccer players wearing full protective equipment.

DESIGN

Crossover study.

SETTING

University sports medicine clinic.

PATIENTS OR OTHER PARTICIPANTS

A total of 146 university varsity athletes, consisting of 62 football, 45 ice hockey, and 39 soccer players.

INTERVENTION(S)

Athletes were assessed for different airway and physical characteristics. Three investigators then evaluated the effectiveness of different bag-valve-mask (BVM) ventilation techniques in supine athletes who were wearing protective equipment while inline cervical spine immobilization was maintained.

MAIN OUTCOME MEASURE(S)

The effectiveness of 1-person BVM ventilation (1-BVM), 2-person BVM ventilation (2-BVM), and inline immobilization and ventilation (IIV) was judged by each investigator for each athlete using a 4-point rating scale.

RESULTS

All forms of ventilation were least difficult in soccer players and most difficult in football players. When compared with 1-BVM, both 2-BVM and IIV were deemed more effective by all investigators for all athletes. Interference from the helmet and stabilizer were common reasons for difficult ventilation in football and ice hockey players.

CONCLUSIONS

Sports medicine professionals should practice and be comfortable with different ventilation techniques for athletes wearing full equipment. The use of a new ventilation technique, termed inline immobilization and ventilation, may be beneficial, especially when the number of responders is limited.

National athletic trainers' association position statement: acute management of the cervical spine-injured athlete

OBJECTIVE

To provide certified athletic trainers, team physicians, emergency responders, and other health care professionals with recommendations on how to best manage a catastrophic cervical spine injury in the athlete.

BACKGROUND

The relative incidence of catastrophic cervical spine injury in sports is low compared with other injuries. However, cervical spine injuries necessitate delicate and precise management, often involving the combined efforts of a variety of health care providers. The outcome of a catastrophic cervical spine injury depends on the efficiency of this management process and the timeliness of transfer to a controlled environment for diagnosis and treatment.

RECOMMENDATIONS

Recommendations are based on current evidence pertaining to prevention strategies to reduce the incidence of cervical spine injuries in sport; emergency planning and preparation to increase management efficiency; maintaining or creating neutral alignment in the cervical spine; accessing and maintaining the airway; stabilizing and transferring the athlete with a suspected cervical spine injury; managing the athlete participating in an equipment-laden sport, such as football, hockey, or lacrosse; and considerations in the emergency department.
