目的 探讨家庭协同干预模式对于改善小儿慢性持续期支气管炎雾化吸入治疗后气道功能的效果。方法 选取2020年9月-2021年10月我院收治的小儿慢性持续期支气管炎儿120例，根据随机数表法分为协同组和对照组，对照组采用综合基础护理，协同组在此基础上采用家庭协同干预措施，比较两组患儿症状消失时间和住院时间，观察两组患儿雾化吸入时间和依从性差异，比较两组患儿气道功能指标和血气指标变化情况，并对患儿家属满意度进行比较。结果 协同组患儿退热时间、止咳时间、哮鸣音消失时间和住院时间明显少于对照组（t=4.859、9.014、2.404、6.130，P<0.05）。协同组患儿完成雾化吸入时间少于对照组，差异有统计学意义（t=13.449，P=0.000）；协同组患儿依从性很好例数多于对照组，依从性差例数少于对照组，差异有统计学意义（χ2=4.937、5.065，P<0.05）。干预后协同组患儿达峰容积比、潮气量、达峰时间比高于对照组，呼吸频率、潮气呼吸呼气峰流速低于对照组（P<0.05）。干预前两组患儿血气指标无明显差异（P>0.05）；干预后协同组患儿SaO2、PaO2明显高于对照组，PaCO2低于对照组（P<0.05）。协同组患儿家属满意度（93.33%）明显高于对照组（83.33%），差异有统计学意义（χ2=8.060，P=0.018）。结论 家庭协同干预模式对于改善小儿慢性持续期支气管炎雾化吸入治疗后气道功能，促进患儿症状恢复，缩短住院时间，患儿依从性和家属满意度较高，值得儿科进一步推广使用。

Objective Investigate the effect of family coordinated intervention mode on improving airway function in children with chronic persistent bronchitis after aerosol inhalation.Methods A total of 120 children with chronic persistent bronchitis admitted to our hospital from September 2020 to October 2021 were selected. According to the random number table method, they were divided into synergy group and control group. The control group adopted comprehensive basic care, and the synergy group adopted family coordinated intervention on this basis. The differences in atomization inhalation time and compliance between the two groups were observed, the changes of lung function indexes and blood gas indexes between the two groups were compared, and the satisfaction of the family members of the children was compared.Results The cough relieving time, fever relieving time, asthma disappearance time and hospital stay time in the coordination group were significantly shorter than those in the control group, with statistically significant differences (t=4.859, 9.014, 2.404, 6.130, P<0.05). The time to complete atomization inhalation in the coordination group was less than that in the control group (t=13.449, P=0.000). The number of patients with good compliance in the synergy group was higher than that in the control group, and the number of patients with poor compliance was lower than that in the control group, with statistical significance (χ2=4.937, 5.065, P<0.05). After intervention, the tidal volume, peak volume ratio and peak time ratio in the collaborative group were higher than those in the control group, and the peak expiratory flow rate and respiratory frequency of the humid respiration were lower than those in the control group, with statistical significance (P<0.05). There was no significant difference in blood gas indexes between the two groups before intervention (P>0.05). After intervention, SaO2 and PaO2 in the coordination group were significantly higher than those in the control group, while PaCO2 was lower than those in the control group, with statistical significance (P<0.05). The satisfaction of family members in the coordination group (93.33%) was significantly higher than that in the control group (83.33%), and the difference was statistically significant (χ2=8.060, P=0.018).Conclusion Family coordinated intervention mode can improve the airway function after atomization inhalation treatment for chronic persistent bronchitis in children, promote the recovery of symptoms, shorten the length of hospital stay, and improve the compliance and family satisfaction of children, which is worthy of further promotion in pediatrics.
