Abstract：Objective:To investigate the optimal frequency of airway humidification in early postoperative laryngectomy patients.Methods:A total of 108 laryngeal cancer patients who underwent laryngectomy and tracheotomy in the Otolaryngology Department of a Grade Ⅲ hospital in Shandong province from February 2020 to February 2022 were selected as the study objects,and were divided into 3 groups by random number table method,with 36 cases in each group.Group A received hourly airway humidification,Group B received airway humidification every two hours,and Group C received airway humidification every three hours.The study aimed to compare the effect of airway humidification on airway complications,daily sputum production,and patient comfort among the three groups.Results:The humidification satisfaction of group B was higher than that of group A and Group C at the first 4 days after laryngectomy(P＜0.05),and there was no statistically significant difference in humidification satisfaction between groups 5 to 7 days after laryngectomy(P＞0.05).The incidence of irritating cough in group B was lower than that in groups A and C(P＜0.05),and there was no significant difference in the incidence of other airway complications among the three groups(P＞0.05).The number of daily sputum aspiration in group A was higher than that in groups B and C(P＜0.05).The comfort score of group B was significantly higher than that of groups A and C(P＜0.05).Conclusions:Oxygen spray inhalation every 2 h can effectively improve the satisfaction of early airway humidification,reduce the incidence of irritating cough and improve the comfort of patients,and is an ideal frequency of atomization after laryngectomy.
