Brief summary
Airway management in cervical spine injury is complicated ,as the established way of achieving the airway controlby direct laryngoscopy using Macintosh laryngoscope will have distracting injuries on the cervical cord, if there is unstable cervical spine injury. In these cases , it is proven that application of manual in line axial stabilisation (MIAS) will counteract the forces of direct laryngoscopy and reduce the further damage. At the same time MIAS create significant difficulty for laryngoscopy. The idea behind this study was to verify whether simulated difficult airway scenarios , as created in our study by application of MIAS manouvere can be optimally managed with videolaryngoscopy in comparison to conventional direct laryngoscopy

CMAC video laryngoscope is having same conventional Macintosh Laryngoscope blade, but with a camera. Essentially it will be indirect view in contrast to direct view by Macintosh Laryngoscope. The laryngoscopy will be done by single experienced( in CMAC) anesthetist of consultant grade Intubation difficulty scale score is recorded . Which reaches higher score if there is change in hands, device or technique. Failed intubation in one technique yield infinite score ( as per Intubation difficiculty scale scoring, 0: difficulty,8 (infinite): impossible to intubate) )and suitable alternative will be employed in securing intubation or ventilation. Manual In line Axial Stabilisation(MIAS) is essentially proven step in preventing the further damage in C-spine injury . A trained anesthetist will be employing MIAS manouvere before intubation attempts.Essentially MIAS involves a trained person stabilizing the head and neck by crouching beside the intubator with hands placed on the patient’s mastoid processes or cradling the occiput giving sufficient counter pressure to prevent neck movements during laryngoscopy.
