Abstract

Background: In patients with cervical spine pathology, manual in line stabilization for cervical spine immobilization may leads to obscured laryngeal view on conventional laryngoscopy leading to difficulty in intubation. Truview® EVO2 has been shown to ease the intubation in patients with normal and difficult airway. King Vision® video laryngoscope is a newly introduced intubating device with an attached screen to ease the intubation.

Aims: To compare the ease of intubation using Truview® EVO2 and King Vision® video laryngoscope in patients with immobilized cervical spine. Settings and

Design: Prospective Randomized comparative study.

Methods and Material: Sixty ASA I-II patients with elective cervical spine surgery were recruited for the study. Patients were randomly allocated by computer generated random number table into two groups comprising of 30 patients each. Following induction of anaesthesia, laryngoscopy was performed using the allocated study device and the tracheal intubation was done. Parameters of IDS score, time taken for intubation were recorded. Post intubation haemodynamic changes and airway related complications were also noted.

Statistical analysis: Conducted using SPSS 17.0 version. Results: Success rate of intubation with both devices was 100%.However no statistical significance difference between mean IDS score between the two devices has been found. The time taken for intubation was less with King Vision® when compared to Truview®. Hemodynamic parameters during intubation and post intubation were comparable and no major complication in both groups.

Conclusion: Both video laryngoscopes are reliable in case of cervical spine surgery patients using manual in line stabilization with 100% success rate and good glottic view.
