“…Thus, the patient could be removed on this pad as on a patient transfer sheet with hand straps. This idea is based on extrication techniques used in motorsports, where drivers are rescued within their seat [8] . This intervention must be performed by at least two persons.…”

Objectives: The extrication of patients following a road traffic collision is among the basic procedures in emergency medicine. Thus, extrication is a frequently performed procedure by most of the emergency medical services worldwide. The appropriate extrication procedure depends on the patient's current condition and accompanying injuries. A rapid extrication should be performed within a few minutes, and the cervical spine (at least) should be immobilized. To our knowledge, the scientific literature and current guidelines do not offer detailed recommendations on the extrication of injured patients. Thus, the aim of the current study is to compare the effectiveness of spinal stabilization during various out-of-hospital extrication procedures. Methods: This is an explorative, biomechanical analysis of spine motion during different extrication procedures on an example patient. Movement of the cervical spine was measured using a wireless human motion tracker. Movement of the thoracic and lumbar spine was quantified with 12 strain gauge sensors, which were positioned paravertebrally on both sites along the thoracic and lumbar spine. To interpret angular movement, a motionscore was developed based on newly defined axioms on the biomechanics of the injured spine. Results: Self-extrication showed the least spinal movement (overall motionscore sum = 667). Movement in the cervical spine could further be reduced by applying a cervical collar. The extrication by a rescue boa showed comparable results in overall spinal movement compared to the traditional extrication via spineboard (overall motionscore sum = 1862vs. 1743). Especially in the cervical spine, the spinal movement was reduced (motionscore sum = 339 vs. 595). However, the thoracic spine movement was increased (motionscore sum = 812 vs. 432). Conclusion: In case of a suspected cervical spine injury, guided self-extrication seems to be the best option. If the patient is not able to perform self-extrication, using a rescue boa might reduce cervical spinal movement compared to the traditional extrication procedure. Since promising results are shown in the case of extrication using a patient transfer sheet that has already been placed below the driver, future developments should focus on novel vehicle seats that already include an extrication device.

Because spinal cord injuries can have fatal consequences for injured race car drivers, prehospital treatment of spinal injuries is a major concern in motor sports. A structured procedure for assessing trauma patients and their treatment should follow established ABCDE principles. Only then, a stable patient could be further examined and appropriate measures can be undertaken. For patients in an acute life-threatening condition, rapid transport must be initiated and should not be delayed by measures that are not indicated. If a competitor must first be extricated from the racing vehicle, the correct method of extrication must be chosen. To avoid secondary injury to the spine after a racing accident, in-line extrication from the vehicle and immobilization of the patient are standard procedures in motor sports and have been used for decades. Since immobilization can be associated with disadvantages and complications, the need for immobilization of trauma patients outside of motor sports medicine has become the subject of an increasing number of reports in the scientific literature. Even in motor sports, where specific safety systems that offer spinal protection are present, the indications for spinal immobilization need to be carefully considered rather than being blindly adopted as a matter of course. The aim of this article is to use recent literature to present an overview about the treatment of spinal injuries in motor sports. Further, we present a new protocol for indications for immobilizing the spine in motor sports that is based on the ABCDE principles and takes into account the condition of the patient.

Purpose The appropriate extrication techniques for trauma patients after car accidents remain a topic of controversy. Various techniques for immobilizing the cervical spine during prehospital extrication have been investigated. Methods This explorative study compared the amount of spinal motion during five different extrication procedures from a racecar and a rallycar performed by two teams: a professional motorsport extrication team and a team of professional emergency medical technicians (EMTs). Two different microelectromechanical systems were used to measure spinal motion, and a motionscore was calculated to compare the amount of remaining spinal motion. A high motionscore indicates high remaining motion and a low motionscore indicates low remaining motion. Results The use of an extricable seat results in a mean overall motion score of 1617 [95% CI 308–2926]. Emergency extrication without equipment resulted in the lowest overall motionscore 1448 [95% CI 1070–1826]. In case of urgent extrication the Extrication team attained a motionscore of 2118 [95% CI 517–3718] and the EMT team a motionscore of 2932 [95% CI 1427–4435]. When performing the procedure with the aid of a rescue boa, the EMT team achieved an overall mean motionscore in the same range 2725 [95% CI 568–4881] with boa vs. 2932 [95% CI 1427–4435] without boa. When mean scores of individual spinal segments were analyzed, we found that the EMT team did especially worse in immobilizing the cervical spine 198 vs. 758. Conclusions Regular training of extrication procedures has paid off considerably in reducing spinal movement during extrication from a racecar. If an extricable seat is available, extrication should be performed using it. However, if emergency extrication is necessary, an additional manual cervical spine immobilization should be conducted using the Rautek maneuver to sufficiently reduce cervical spine movement.
