Prehospital clinical clearance of the cervical spine: a prospective study.

Physician clinical clearance of the cervical spine after blunt trauma is practiced in many trauma centers. Prehospital clinical clearance of the cervical spine (c-spine) performed by emergency medical services (EMS) personnel can decrease cost, improve patient comfort, decrease complications, and decrease prehospital time. The purpose of this study was to assess whether EMS personnel can effectively clinically clear the c-spine of injury in the prehospital setting. All paramedics from a single urban fire department were trained in clinical clearance of the c-spine. During the 14-month period from January 2008 through March 2009, clinical examination of the c-spine was performed by paramedics on blunt trauma patients in the prehospital setting. Paramedics immobilized the c-spine and delivered the patients to the University of South Alabama Medical Center. After trauma center arrival, paramedics documented their clinical examination of the c-spine in a computerized data collection form. Paramedic clinical findings were compared with trauma surgeon clinical examination findings and computed tomographic findings of the c-spine. All patients had prehospital Glasgow Coma Score 14 or greater. Patients were not excluded for distracting injuries. One hundred ninety-three blunt trauma patients were entered. Sixty-five (34%) c-spines were clinically cleared by EMS. There were no known missed injuries in this patient group. Eight (6%) patients who were not clinically cleared by EMS were diagnosed with c-spine injury. Trauma surgeons clinically cleared 135 (70%) of the patients with no known missed injury. EMS personnel in the prehospital setting may reliably and effectively perform clinical clearance of the c-spine. Further prospective study for prehospital c-spine clinical clearance is warranted.

Clinical clearance of the cervical spine in patients with distracting injuries: It is time to dispel the myth.

OBJECTIVE: The purpose of this study was to prospectively assess the sensitivity and efficacy of clinical examination for screening of cervical spine (c-spine) injury in awake and alert blunt trauma patients with concomitant "distracting injuries." METHODS: During the 24-month period from December 2009 to December 2011, all blunt trauma patients older than 13 years were prospectively evaluated with a standard cervical spine examination protocol by the trauma surgery team at a Level 1 trauma center. Awake and alert patients with a Glasgow Coma Score (GCS) ≥14 underwent clinical examination of the cervical spine. Clinical examination was performed regardless of "distracting injuries." Patients without complaints of pain or tenderness on physical exam had their cervical collar removed, and the c-spine was considered clinically cleared of injury. All awake and alert patients with "distracting injuries," including those clinically cleared and those with complaints of c-spine pain or tenderness underwent computerized tomographic (CT) scanning of the entire c-spine. "Distracting injuries" were categorized into three anatomic regions: head injuries, torso injuries and long bone fractures. Patients with minor distracting injuries were not considered to have a "distracting injury." RESULTS: During the 24-month study period, 761 blunt trauma patients with GCS ≥14 and at least one "distracting injury" had been entered into the study protocol. Two-hundred ninety-six (39%) of the patients with "distracting injuries" had a positive c-spine clinical examination, 85 (29%) of whom were diagnosed with c-spine injury. Four hundred sixty-four (61%) of the patients with "distracting injuries"' were initially clinically cleared, with one patient (0.2%) diagnosed with a c-spine injury. This yielded an overall sensitivity of 99% (85/86) and negative predictive value greater than 99% (463/464) for cervical spine clinical examination in awake and alert blunt trauma patients with "distracting injuries." CONCLUSIONS: In the awake and alert blunt trauma patient with "distracting injuries," clinical examination is a sensitive screening method for cervical spine injury. Radiological assessment is unnecessary for safe clearance of the asymptomatic cervical spine in awake and alert blunt trauma patients with "distracting injuries." These findings suggest the concept of "distracting injury" in the context of cervical spine clinical examination is invalid. Expanding the utility of cervical spine clinical examination to patients with "distracting injuries" allows for significant reduction of both healthcare cost and radiation exposure.
