Objective: To explore the application of high-frequency ventilation of general anesthesia machine in the removal of tracheobronchial foreign bodies in children under deep sedation anesthesia. Methods: Thirty cases of tracheobronchial foreign body removal under bronchoscopy in children, aged 2-4 years, were retrospectively reviewed. The study group (M group) used deep sedation anesthesia, while the control group (P group) used conventional anesthesia. Oxygen supply: A rigid bronchoscope was inserted into the trachea and then connected to a Dräger anesthesia machine for high-frequency ventilation. The vital signs of the children were monitored, the SPO2 of the children, the satisfaction score of the surgeon and the complications were recorded. Results: The foreign bodies were successfully removed in all 30 cases, and there was no death or serious postoperative complications; the satisfaction score of surgeons in group M was higher than that in group P (P<0.05). The number of breath-holding or coughing cases, apnea cases, SpO2 decrease cases and body movement cases in group M were lower than those in group P (P<0.05). Conclusion Under the depth of the depression, the use of ordinary anesthesia machines high-frequency ventilation, the physiological interference in children is small, clear, and improve patient safety.
