Objective  To compare the application effects of two kinds of oxygen and nebulizer inhalation devices applied to patients undergoing partial hepatectomy, with a view to providing reference for clinical selection oxygen and nebulizer inhalation modality. Methods  A prospective case-control study was used to select 228 patients who required oxygen inhalation and nebulization after hepatectomy under general anesthesia in the Department of Liver Surgery of West China Hospital of Sichuan University from January to December 2022 as study subjects, and were randomly divided into two groups: grouping group (n=77) and integrating group (n=151). The traditional oxygen inhalation device and atomization device (grouping oxygen inhalation atomization device) commonly used in clinic were used in the grouping group, and the humidifying bottle and humidifying water were replaced every 24 hours. The integrating group adopts a new device (integrated oxygen atomization inhalation device) which integrates oxygen inhalation and atomization functions. The integrating group was divided into integrating group 1 (n=77) and integrating group 2 (n=74) according to the different time of changing the humidifying bottle and humidifying water. The time for replacing the humidifying bottle and humidifying water in the integrating 1 was the same as that in the grouping group. The time for replacing the humidifying bottle and humidifying water in the integrating group 2 was 48 h after used, and replace again it after 72 hours of used. Samples from different parts of the grouping group and the integrating group 1 were collected at 24 h, 48 h, 72 h, 96 h and 120 h after oxygen inhalation, respectively, for colony culture. In the integrating group 2, samples were taken for colony culture when the device was changed twice (48 h and 120 h). At the same time, the nurses’ fogging operation time and the fogging noise of the two groups were measured. The self-made patients’ satisfaction questionnaire and nurses’ questionnaire were used to investigate the satisfaction of two groups of patients and 30 medical staff respectively. Results  There were no statistically significant difference in the number of bacterial colonies between the grouping group and the integrating group 1 at different time periods and between the two groups at the same time (P＞0.05). In terms of atomization performance, atomization noise in the integrating group was lower than that of the grouping group (P＜0.05), and the atomization preparation and disposal time in the integrating group were shorter than that of the grouping group (P＜0.05). The patients and nurses were more satisfied with the integrating group (P＜0.05). Conclusions  There is no difference in pollution risk between the integrated oxygen atomization bottle and the grouped oxygen atomization bottle. The atomization performance and humidification performance of the integrated oxygen atomization bottle are better than that of the grouped oxygen atomization bottle. The noise generated during operation is small, the comfort of patients is high, and the operation time of nurses can be shortened and the work efficiency can be improved, which has high clinical application value.
