Abstract:
Objective:To study the application value of humidified high flow nasal cannula (HHFNC) combined with visual laryngoscopy in the arytenoid cartilage dislocation. Methods:Twenty-nine patients with arytenoid cartilage dislocation were randomly double-blind into HHFNC group and general nasal catheter oxygen suction group, and the intraoperative and postoperative evaluation indicators, anesthesia-related indicators and postoperative vocal cord were compared. Results:There were statistically significant differences in intraoperative blood oxygen saturation, microstream end-tidal carbon dioxide partial pressure EtCO₂, respiratory rate and respiratory intervention times between the two groups (P<0.05), and statistically significant differences in postoperative heart rate, oxygen saturation and respiratory rate (P<0.05). After reduction, the voice disturbance index, the degree of voice abnormality, rough voice, breath sound, powerless pronunciation and catatonic pronunciation changed significantly after operation. Conclusion:HHFNC combined with visual laryngoscopy in the arytenoid cartilage dislocation has high anesthetic safety, good cooperation of patients, and good surgical effect.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
