Spinal cord injury (SCI) refers to severe traumatic damage to the brain-to-body signaling bundle, resulting in bruising or partial to total tearing of the spinal cord. This type of injury can manifest immediately after a traumatic event or develop later during patient handling and transportation. To mitigate or prevent further SCI, prehospital care is essential. Key elements of prehospital care include patient assessment, cervical spine immobilization, cardiovascular support with mean arterial blood pressure maintained above 85 mmHg, and careful airway management possibly involving manual in-line stabilization (MILS) during intubation.

Methylprednisolone (MPS) and other pharmacological treatments have not provided clinically meaningful benefits for individuals with SCI. The use of MPS in the prehospital context is not currently endorsed. The effectiveness of pharmacological drugs in therapeutic hypothermia remains uncertain. Special consideration is given to the risk of cervical spine damage during endotracheal intubation, where the MILS technique can significantly limit C-spine motion. However, this method may also restrict mouth opening and compromise laryngoscopic visibility. Recent advancements such as video laryngoscopes, including Airtraq and AirWay Scope (AWS), can enhance intubation conditions compared to traditional devices and reduce C-spine extension movements during the process.

The annual incidence of SCI in the United States is estimated at 43 to 77 cases per million, totaling about 20,000 cases each year. Approximately 20 percent of individuals with SCI do not survive long enough to reach a hospital. With around 200,000 people currently living with SCI in the U.S., the male-to-female ratio stands at about 4:1. In 1990, projected annual healthcare costs related to SCI reached approximately four billion dollars.

Treatment considerations are paramount when addressing SCI, particularly damage to the cervical spine, as it can mean the difference between life and death. Conditions such as hypercapnia, aspiration pneumonia, and respiratory arrest can lead to hypoxic brain injuries and complicate endotracheal intubation. Airway management is crucial for ensuring short-term survival and potential recovery of trauma patients. Among various methods utilized by emergency medical services (EMS), endotracheal intubation is generally considered the gold standard for airway management due to its effectiveness over other strategies.

The recognition and appropriate management of spinal column injuries are essential for preventing permanent neurological deficits and loss of function. A careful and cautious approach is required when treating acutely injured patients before hospital transfer. The likelihood of cervical SCI can increase in cases of severe closed-head trauma, with an estimated occurrence rate of 2% among blunt trauma patients. Additionally, patients with acute SCI face the risk of neurological decline.

A systematic review was conducted using databases such as PubMed, Google Scholar, and Cochrane Central Register of Controlled Trials (CENTRAL) to gather relevant studies. The search utilized keywords focusing on C-spine stabilization, cervical cord injuries, prehospital management, airway management, and related terms. Inclusion criteria aimed at ensuring relevant empirical studies while excluding non-empirical research like case studies and surveys.

Prehospital management for combat casualties with suspected spinal injuries requires adherence to protocols consistent with Advanced Trauma Life Support (ATLS). The main differences here compared to civilian trauma care arise from the constraints and demands of a war environment. First responders often prioritize rapid extrication from danger over spinal stability. Consequently, spinal immobilization may be postponed until further resources become available.

In the context of prehospital care, selective spine immobilization should be implemented when patients display signs indicating potential spinal injuries such as pain, altered neurological function, and other distractive injuries. A multicenter study emphasized the importance of recognizing these parameters to facilitate appropriate immobilization practices. It is crucial to note that while spinal instability may not be immediately evident, preventive immobilization remains essential in reducing the risk of neurological damage until conclusive assessments can be made through radiological investigations.

Effective trauma airway management focuses on ensuring adequate oxygenation and ventilation. Emergency medical personnel must swiftly evaluate whether basic airway management techniques suffice or if advanced treatments are necessary. Notably, patients presenting with traumatic brain injuries may lack protective airway reflexes, necessitating endotracheal intubation backed by drug-assisted airway management strategies to facilitate an unobstructed airway.

The preservation of the patient’s spinal integrity during transportation is critical, particularly in challenging terrains encountered in military operations. When extricating patients with suspected spinal cord injuries, best practices involve utilizing lateral support devices along with maintaining head and neck alignment while ensuring minimal pain or deformity during movement. In combat scenarios, the initial assessment focuses on the primary survey using ATLS protocols to identify and address spinal injuries effectively.

Comprehensive evaluation and appropriate imaging, such as CT scans, are prioritized to assess spinal injuries accurately while minimizing time delays in treatment. Emergency care providers must be acutely aware of the potential complications associated with spinal injuries during aeromedical transport to facilitate optimal outcomes. Overall, a meticulous approach to identifying and managing spinal cord injuries is vital in enhancing recovery prospects and minimizing long-term neurological damage.

Research indicates that continuous advancements in clinical practices and treatment protocols will improve the management of spinal injuries in both civilian and combat environments. Collaboration among medical professionals, timely intervention, and adherence to established guidelines can significantly enhance patient care and outcomes. Future studies should focus on refining training and protocols to further optimize prehospital care and patient recovery.

The overarching goal remains to enhance the understanding of spinal cord injuries while fostering a comprehensive approach that integrates advancements in medical practices. Through meticulous attention to clinical detail, proficiency in emergent care, and a commitment to evolving standards, healthcare professionals can significantly impact patient recovery trajectories and overall quality of life.
