【 摘 要 】

Objective: We aimed to compare C-MAC videolaryngoscope (VLC) with Macintosh laryngoscope with regard to the laryngoscopic view, the need for external laryngeal manipulation, requirement of airway adjuncts like stylet, time required to complete the tracheal intubation and the hemodynamic changes in Mallampati class 2 and 3 patients. Methodology: Sixty patients who were admitted for elective surgery requiring general anesthesia with endotracheal intubation were randomly allocated to proceed with endotracheal intubation using the conventional Macintosh VLC (Group A) or the C-MAC VLC (Group B). Following a standardised general anesthetic protocol, time for intubation, laryngoscopic view, need for external manipulation, and hemodynamic parameters during and after intubation were registered during study period. Results: It was observed that C-MAC VLC improves the laryngoscopic view in predicted difficult airway setting, and thus reduces the need for external laryngeal manipulation and the use of stylet. However, the hemodynamic stress response was significant with C-MAC VLC than Macintosh laryngoscopy. There was significant reduction in time taken for intubation with conventional Macintosh laryngoscope when compared with C-MAC® VLC. The median total intubation time for the Macintosh and C-MAC® laryngoscopes was 23.8 sec and 35.33 sec respectively (p = 0.000).
