Objective: To analyze the therapeutic effect of the combination of heating humidifier and closed sputum suction in patients who are treated with artificial airway in neurosurgery. 

Methods: According to the principle of random allocation, 110 patients with artificial airways in neurosurgery are selected and divided into research group and control group, and each group contains 55 cases. The study group is treated with a combination of heating humidifier and closed sputum suction, while artificial nose combined with open sputum suction is used in the control group to treat patients with artificial airways in neurosurgery. The vital signs, sputum viscosity, complications, incidence of sputum scab, pulmonary infection, blood oxygen saturation, complications, positive rate of sputum bacterial culture and the number of bacterial strains, the number of sputum suction and sputum suction volume, humidification effect, artificial airway indwelling time and hospital stay. 

Results: The heart rate of the experimental group in the study group was 85.64 ± 10.46, the systolic pressure was 114.63±7.31 mmHg, the diastolic pressure was 90.27±6.57 mmHg, the average number of sputum suctions per day was 13.06±1.31, and the average amount of sputum suctions per day was 45.72±1.98; The application time of artificial airway was 8.26±2.62, and the average hospitalization time was 13.74±3.51. All test indexes in the artificial airway group were better than those in the control group (P<0.05 or P<0.001). 

Conclusion: Heating humidifier combined with closed sputum suction method has good therapeutic effect in patients with artificial airway in neurosurgery, patients’ satisfaction can be improved and the recovery of patients can be promoted..
