Abstract

This study aimed to evaluate the effects of high-flow nasal oxygen and conscious sedation on respiratory rate, heart rate, and blood pressure during awake fiberoptic intubation in patients with maxillofacial abscess. This was a randomized controlled clinical interventional study involving 102 patients undergoing surgery for maxillofacial abscess with trismus. Patients were divided into two groups: Group 1 (n = 51) received preoxygenation with high-flow nasal oxygen, conscious sedation, and topical anesthesia of the upper airway; Group 2 (n = 51) received preoxygenation with low-flow nasal oxygen and topical anesthesia of the upper airway without sedation. Results: Immediately before intubation, when the fiberoptic scope passed through the glottis, and immediately after intubation, respiratory rate, heart rate, systolic blood pressure, and mean arterial pressure were significantly lower in Group 1 than in Group 2 (p < 0.05). Conclusion: Preoxygenation with high-flow nasal oxygen combined with conscious sedation helps stabilize respiratory rate, heart rate, and blood pressure during awake fiberoptic intubation in patients with maxillofacial abscess.
