To assess current practice in cervical spine clearance across major trauma centres in England and review current guidelines.
An electronic survey was sent to lead trauma clinicians at 22 major trauma centres in England. This assessed the clinical decision tools used, the choice of initial imaging technique, and the methods used to clear the cervical spine in alert and obtunded patients without focal neurology, and where initial imaging was normal. British Orthopaedic Association Standards for Trauma (BOAST) 2 and Eastern Association for Surgery for Trauma (EAST) guidelines were used as standards.
Eighteen out of the 22 (82%) centres responded by completing the survey. Most (71%) centres used the Canadian C-Spine Rule for clearing the cervical spine clinically. Seventy-two percent of centres preferred computed tomography (CT) as the first-line imaging technique, the choice based on age of patient and mechanism of injury. If the initial CT imaging was normal, magnetic resonance imaging (MRI) was performed in 52% of centres to clear the cervical spine, with half of these centres stating that they would discuss further imaging with a radiologist first. The practice across centres was highly variable for the obtunded patient, with most centres preferring continuing immobilisation or MRI to clear the cervical spine, with a small minority removing spinal precautions when a high-quality multidetector CT was normal.
Multidetector CT is the preferred initial imaging technique across most major trauma centres in England when blunt cervical spine trauma is suspected. There is widespread reliance on MRI to clear the cervical spine in both alert and obtunded patients, if initial CT imaging is normal and there is no focal neurology on clinical assessment. This calls for greater awareness of the reliability of a high-quality normal multidetector CT examination in clearing the cervical spine in the absence of focal neurology.
评估英格兰各大创伤中心颈椎评估的当前实践情况,并回顾当前指南。
向英格兰22家主要创伤中心的创伤科主任发送了电子调查问卷。该问卷评估了所使用的临床决策工具、初始成像技术的选择,以及在无局灶性神经功能障碍且初始成像正常的清醒和昏迷患者中清除颈椎的方法。英国骨科协会创伤标准(BOAST)2和东部创伤外科学会(EAST)指南被用作标准。
22家中心中有18家(82%)通过完成调查问卷进行了回复。大多数(71%)中心在临床上使用加拿大颈椎规则来清除颈椎。72%的中心倾向于将计算机断层扫描(CT)作为一线成像技术,这一选择基于患者年龄和损伤机制。如果初始CT成像正常,52%的中心会进行磁共振成像(MRI)以清除颈椎,其中一半的中心表示他们会首先与放射科医生讨论进一步的成像检查。各中心对昏迷患者的处理方式差异很大,大多数中心倾向于继续固定或进行MRI以清除颈椎,少数中心在高质量多层螺旋CT正常时会解除脊柱防护措施。
在怀疑有钝性颈椎创伤时,多层螺旋CT是英格兰大多数主要创伤中心首选的初始成像技术。如果初始CT成像正常且临床评估无局灶性神经功能障碍,无论是清醒还是昏迷患者,普遍依赖MRI来清除颈椎。这就要求在没有局灶性神经功能障碍的情况下,提高对高质量正常多层螺旋CT检查在清除颈椎方面可靠性的认识。
