, Abstract—Background: Selective cervical spine immobilization performed by Emergency Medical Services (EMS) is being utilized with increasing frequency. These protocols, although very sensitive, still include subjective data such as ‘‘mild cervical discomfort.’’ The aim of this study is to create an objective clinical decision rule that would enhance the selective approach for cervical spine immobilization in patients aged 16–60 years. Study Objective: It is hypothesized that, in amotor vehicle crash, the integrity of the involved vehicle’s glass window and airbag status is an excellent objective measure for the amount of energy a vehicle occupant has experienced during the crash. GLass intact Assures Safe Spine (GLASS) is an easy and objectivemethod for evaluation of the need for prehospital cervical spine immobilization. Methods: A retrospective cohort study was performedwith samplemotor vehicle crash cases to evaluate the performance of the GLASS rule. The National Accident Sampling System-Crashworthiness Data System (NASSCDS) was utilized to investigate tow-away motor vehicle crashes, including their glass damage characteristics and occupant injury outcomes, over an 11-year period (1998– 2008). Sample occupant cases selected for this study were patients aged 16–60 years, who were belt-restrained front seat occupants involved in a crash with no airbag deployment, and no glass damage before the crash. Results: A total of 14,191 occupants involved in motor vehicle crashes were evaluated in this analysis. The results showed that the sensitivity of the GLASS rule was 95.20% (95% confidence interval [CI] 91.45–98.95%), the specificity was 54.27% (95% CI 53.44–55.09%), and the negative predictive value was 99.92% (95% CI 99.86–99.98%). Conclusion: The GLASS rule presents the possibility of a novel, more objective tool for cervical spine clearance. Prospective evaluation is

GLASS Clinical Decision Rule Applied to Thoracolumbar Spinal Fractures in Patients Involved in Motor Vehicle Crashes

INTRODUCTION There are established and validated clinical decision tools for cervical spine clearance. Almost all the rules include spinal tenderness on exam as an indication for imaging. Our goal was to apply GLASS, a previously derived clinical decision tool for cervical spine clearance, to thoracolumbar injuries. GLass intact Assures Safe Spine (GLASS) is a simple, objective method to evalua...

Effect of cervical collars on intracranial pressure in patients with head neurotrauma

Trauma patients are at high risk of cervical and associated injuries. The standard protocol includes immobilization of the cervical spine in a polytrauma as it will help to prevent spinal injuries in the prehospital settings. Hard cervical collar (or alternatives) is routinely used until the cervical spine clearance is obtained . In patients with traumatic brain injury avoiding any kind of mane...

Pediatric Patient Safety in Emergency Medical Services

Since the publication of early studies highlighting the prevalence, impact, and costs of medical errors in the 1990s, patient safety has been the subject of considerable attention and study, primarily focused on adults and the inpatient setting. Less progress has been made with regard to pediatric patient safety and even less in the prehospital environment. This article reviews the issues and l...

Comparison of Three Prehospital Cervical Spine Protocols for Missed Injuries

INTRODUCTION We wanted to compare 3 existing emergency medical services (EMS) immobilization protocols: the Prehospital Trauma Life Support (PHTLS, mechanism-based); the Domeier protocol (parallels the National Emergency X-Radiography Utilization Study [NEXUS] criteria); and the Hankins' criteria (immobilization for patients <12 or >65 years, those with altered consciousness, focal neurologic d...

Video laryngoscopy in the prehospital setting.

In the prehospital setting, the emergency care provider must anticipate that some patients will manifest with difficult airways. The use of video laryngoscopy to secure an airway in the prehospital setting has not been explored widely, but has the potential to be a useful tool. This article briefly reviews some of the major video laryngoscopes on the market and their usefulness in the prehospit...
