OBJECTIVE: Our study aimed to compare video laryngoscopy (VL) vs. direct laryngoscopy (DL) for tracheal intubation in adult patients receiving general anesthesia for elective surgery during the COVID-19 pandemic.

PATIENTS AND METHODS: The study included 150 patients 18-65 years old, ASA I-II (American Society of Anesthesiologists), and negative PCR tests before the operation was scheduled for elective surgery under general anesthesia. Patients were subdivided into two groups considering the intubation method: the video laryngoscopy group (Group VL, n=75) and the Macintosh laryngoscopy group (Group ML, n: 75). Demographic data, operation type, intubation comfort, and field of view, intubation times, complications were recorded.

RESULTS: Both groups’ demographic data, complications, and hemodynamic parameters were similar. In Group VL, Cormack-Lehane Scoring values were higher (p<0.001), the field of view was better (p<0.001), and the intubation was more comfortable (p<0.002). The duration for the vocal cord appearance was significantly shorter in the VL group than in the ML group (7.55±1.00 vs. 8.31±2.20 sec, p=0.008, respectively). The beginning of intubation to full ventilation of the lungs was significantly shorter in the VL group than the ML group (12.71±2.72 vs. 17.48±6.8, p<0.001, respectively).

CONCLUSIONS: Using VL in endotracheal intubation may be more reliable in reducing intervention times and the risk of suspected transmission during the COVID-19 pandemic.
