Comparison of direct laryngoscopy with McCoy blade & BPL video laryngoscopy for intubation in patients undergoing elective cervical spine surgery.

Intubating the trachea and securing the airway remains a challenge, although it is a routine practice for the anesthesiologist. There is no single factor to predict the existence of a difficult airway, so difficult airway is not recognized until the induction of anesthesia. Difficult intubation is very subjective and it is difficult to measure the degree of difficulty, as previous studies say that in difficult airway management video laryngoscope improve Cormack- Lehane grade and achieve the same or a higher intubation success rate in less time, compared with direct laryngoscope. After getting clearance from ethical committee, to refine the previous studies we are conducting a study on 60 patients of elective cervical spine surgery and the patients are divided in two groups by random number table with 30 patients in each group, to compare efficacy of BPL video laryngoscopy and direct laryngoscopy with McCoy blade for intubation in patients undergoing elective cervical spine surgery. Patients will be intubated by using BPL video laryngoscope and direct laryngoscope with McCoy blade of respective group patients after giving premedication, preoxygenation for 3 minutes, induction agent and muscle relaxants. The primary objective is to find duration of the tracheal intubation by using BPL video laryngoscope and direct laryngoscope with McCoy blade. The secondary objectives are comparing the visualization of airway between the two groups using Modified Cormack Lehane grading, ease of intubation, to determine intubation difficulty score, to compare the hemodynamic stability while and after insertion of ET Tube into trachea.
