Abstract
Airway management of polytrauma patients with suspected cervical spine injury is the starting point of resuscitation and is a defining competence for the specialty of emergency medicine. Patients with C-spine injury represent a unique health burden, they become dependent on medical devices, suffer from complications of prolonged immobilization in addition to the enormous economic burden.
Polytrauma patients represent a diagnostic difficulty in that they may have other distracting injuries that can divert the physician focus. C-spine injury should be thoroughly searched for in all trauma patients.
Airway management of trauma patients in ED represents a major challenge; it differs from airway management in elective settings in various points including nature of the patient who may present with agitation, hypotension, disturbed level of consciousness and cervical spine affection. Timing is of the essence. Any lag in airway management may have catastrophic sequelae.
Direct laryngoscopy (DL) is the most studied technique for endotracheal intubation as it is the most commonly available tool in emergency settings. Its main limitation is that to achieve ideal glottic visualization a direct line of sight must be present to align the three airway axes.
Video laryngoscopy (VL) utilizes video camera technology to visualize airway structures and facilitate endotracheal intubation. Indirect laryngoscopy via its camera; eliminates the need for a direct line of sight to achieve ideal visualization of airway structures.
Numerous types of VL have been introduced. Generally, they can be categorized into three groups based on their design specifications:
I. Standard blade style.
II. Highly curved or distally angulated blades.
III. Video-laryngoscopes with a tube channel.
Another important application of VL is its educational and training implications. It provides a more accurate representation of airway anatomy, allowing demonstrators, junior physicians, and the surgical team to all see the same thing at the same time, allowing for real-time guiding and instruction.
The C-MAC D-Blade VL represents an important update to the current C-MAC system. It has the same basic design of the C-Mac. It has a unique half-moon shape that leads to an overall higher angulation when compared with the traditional C-MAC blade.
This study was a randomized controlled trial that included 100 polytrauma patients intubated in the
