Spinal cord injuries are devastating events. In the U.S., most are the result of automobile collisions, but falls, penetrating injuries, and blunt trauma can also cause injury to the spinal cord, leading to a respiratory emergency. It is estimated that there are over 11,000 spinal cord injuries each year in the U.S., the majority (80%) of which affect males around the age of 37.¹ When the injuries involve the cervical vertebrae, specifically the midsection (C3 through C5), they can disrupt the phrenic nerve, which controls movement of the diaphragm, rendering the patient unable to breathe on their own. So, today, we’ll explore spinal trauma, and how the combination of early recognition alongside managing the tenuous airway can not only save the life of your patient, but also avoid further injury. Index of SuspicionAs an EMT or Paramedic, it is your responsibility to maintain a high degree of suspicion regarding spinal cord injury whenever you encounter the following injuries:²
If you encounter such injuries, always treat as if the spinal cord has been impacted. It is better to overtreat than undertreat a patient with potential cord damage. The mishandling of a spinal cord patient can aggravate an existing injury or produce a new (sometimes devastating) injury, so handle with care and maintain a high index of suspicion.
Airway ManagementSpinal cord injuries may impact respirations, depending on the height and completeness of cord damage. The higher up on the spine the injury occurs, the more likely it will affect the patient’s breathing. Your first goal is to secure a patient's airway while maintaining cervical immobilization. This may be challenging, if the patient is located in a vehicle and not breathing. Rapid extrication may be necessary, if you are unable to place an OPA and assist respirations (for example, if the patient is still conscious). But you must weigh the consequences of moving a patient with a suspected spinal injury versus the need for airway intervention. Be sure to utilize the jaw-thrust maneuver when opening the airway. In the unresponsive patient, secure patency while another rescuer maintains C-spine alignment, begin bagging, then carefully remove the patient onto a backboard or full body splint. Once the patient has been fully immobilized, and the airway and breathing are secured, continue your assessment. Your concern is not only the height of the injury, but whether it is complete or incomplete. Look for the clues:³
Knowing the diagnostic signs of spinal cord injury can not only assist in recognition, but also in your treatment decisions. The Critical Role of Suction in Spinal Cord InjuriesWhen managing a patient with a suspected spinal cord injury, the role of suction cannot be overstated. Depending on the extent of injury, the patient may be unable to cough or swallow effectively. Suction is a must. Take the portable suction unit with you on all trauma calls, or utilize a small, lightweight unit to stow in the trauma bag. Suction the patient to remove saliva, blood, and vomit, and keep it alongside the patient during movement and transport. Managing a patient with a spinal cord injury requires a high index of suspicion, early recognition, and prompt airway management. So, be alert for the signs and always have suction tools at the ready. ¹ Brown, Robert, et al., (2006), Respiratory Dysfunction and Management in Spinal Cord Injury, Respiratory Care, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2495152/ ² Prehospital Trauma Life Support, (2011), American College of Surgeons, pp. 247. ³ Fox, Adam, (2014), Assessment and Treatment of Spinal Cord Injuries and Neurogenic Shock, JEMS, http://www.jems.com/articles/print/volume-39/issue-11/features/assessment-and-treatment-spinal-cord-inj.html?c=1 Topics: Airway management What is the best way to open the airway of an unresponsive victim with a suspected neck injury?If you think the person may have a spinal injury, place your hands on either side of their head and use your fingertips to gently lift the angle of the jaw forward and upwards, without moving the head, to open the airway. Take care not to move the person's neck. But opening the airway takes priority over a neck injury.
What method should be used to maintain an open airway in an unconscious patient with no spinal injury?8. Tilt the person's head back and lift their chin to keep their airway open. 9. Pinch their nose and cover their open mouth with your open mouth, making an airtight seal.
What Manoeuvre is used to open and maintain the airway of an unconscious patient?The head tilt chin lift technique is applied during mouth-to-mouth resuscitation or to achieve the airway in patients with reduced consciousness.
What would you do if an unconscious casualty has a suspected spinal injury?Managing a spinal injury
Place the unconscious patient in recovery position supporting neck and spine in a neutral position at all times to prevent twisting or bending movements. Maintain a clear and open airway. If the ambulance is delayed, apply a cervical collar, if trained to do so, to minimise neck movement.
