Abstract
Background and Aims: It is challenging even to the most experienced anaesthesiologist to intubate in patients with restricted movement of the cervical spine. The randomized studies comparing King Vision video laryngoscope and McCoy laryngoscope are very limited. Therefore, we planned to study a comparative evaluation of King Vision video laryngoscope and McCoy laryngoscope for tracheal intubation in patients with immobilized cervical spine
Method: This was a prospective randomized study, carried out in patients posted for elective surgery.60 patients were randomly divided in two groups comprising 30 patients each of ASA Grade I or II , age 18-60yrs, either sex and weighing 45-80 kg under General Anaesthesia. Induction was done with inj. propofol 2.0 mg kg-1/iv and inj. succinylcholine 1.5 mg kg-1 /iv were used as muscle relaxant and Intubation was done using/applying standard protocol/technique with either King Vision video laryngoscope or McCoy laryngoscope.
Result: The demographic variables such as age, sex and ASA were similar in both the groups. There was no statistically significant difference. Mean intubation time of patients in Group A was 16.9 ± 3.5 sec and in Group B was 19.3 ± 5.1 sec. The mean intubation time was less in Group A patients and was statistically significant (p = 0.021). There was a statistically significant difference in POGO score of patients in between Group A and Group B (p<0.001). There was no statistically significant difference in IDS of patients in between Group A and Group B (p=0.077). The mean arterial pressure was better in Group A although, there was no statistically significant difference.
Conclusion: We conclude that the King Vision video Laryngoscope is superior to the McCoy laryngoscope if cervical immobilization is anticipated.
