Abstract

Objective: To evaluate the outcomes of video laryngoscopy for endotracheal intubation in patients with respiratory failure at Military Hospital 175 and to identify associated factors. Subjects and Methods: A prospective, descriptive, analytical study was conducted on 79 patients with respiratory failure requiring emergency endotracheal intubation. All patients underwent endotracheal intubation using a video laryngoscope at Military Hospital 175 from October 2023 to October 2025. Results: Among 79 patients, 60.8% were male, with a mean age of 58.6 ± 15.2 years. The most common cause of respiratory failure was pneumonia (43.0%). The overall intubation success rate was 97.5%, with a first-pass success rate of 83.5%. Most patients had favorable laryngeal views, with Cormack–Lehane grades I–II accounting for 94.9%. The mean intubation time was 36.8 ± 18.5 seconds. The complication rate was 25.3%, with hypoxemia (SpO₂ decrease) being the most frequent (12.7%). Factors associated with reduced first-pass success included Mallampati class III–IV, pre-intubation SpO₂ < 90%, crash emergency situations, and the presence of ≥2 predictors of difficult airway (p < 0.05). A duration of ≤30 seconds is associated with a higher likelihood of success (OR = 5.12; p = 0.016). Conclusion: Video laryngoscopy for endotracheal intubation demonstrated a high success rate. Outcomes were associated with airway characteristics, pre-intubation oxygenation status, and emergency conditions. A short execution time is associated with first-attempt success.
