高流量湿化氧疗系统对气管切开患者院内获得性肺炎发生率的影响

摘要

Objective To investigate the effect of high flow oxygen therapy system on the incidence of hospital acquired pneumonia in patients with tracheotomy.Methods 70 patients who separated from the ventilator of tracheoto-my were randomly divided into treatment group (humidified oxygen humidified high flow)and conventional group (tra-ditional artificial humidification oxygen mask)35 cases,arterial oxygen partial pressure (PaO2 ),arterial partial pressure of carbon dioxide (PaCO2 ),oxygen saturation (SaO2 ),the incidence of airway humidification effect of pH value,satis-faction rate and complication were compared between two groups.Results Before the treatment,humidified oxygen ther-apy group and normal group of PaO2 ,PaCO2 ,SaO2 ,pH value of the difference was not statistically significant (P >0.05);4 h treatment,after the treatment of 24h,PaO2 ,SaO2 humidification oxygen therapy group were higher than that in control group (P <0.05 ),there was no significant difference between PaCO2 and the conventional group (P >0.05);after 1 2 h treatment,the two groups of patients with airway humidification was evaluated,humidification oxygen therapy group airway humidification satisfaction was 80% higher than the conventional group 54.29% (P <0.05);hu-midification oxygen therapy group excessive airway humidification of 0% lower than the conventional group 1 1 .43%(P <0.05);the treatment process,oxygen humidification treatment group,the complication rate was 1 1 .43% lower than the conventional group 40 (P <0.05),humidification oxygen therapy group occurs in hospital acquired pneumonia in 6 cases (1 7.1 4%)of 1 4 cases lower than the conventional group (40%),the difference was statistically significant (P <0.05).Conclusion High flow humidification oxygen therapy system can effectively reduce the incidence of hospital ac-quired pneumonia in patients with tracheotomy and maintain stable blood gas levels.%目的：探讨高流量湿化氧疗系统对气管切开患者院内获得性肺炎发生率的影响。方法选取已脱离呼吸机的气管切开患者70例作为研究对象，采用抽签法随机分为湿化氧疗组（高流量湿化氧疗系统）、常规组（传统人工面罩湿化吸氧）各35例，对比两组的动脉血氧分压（PaO2）、动脉血二氧化碳分压（PaCO2）、血氧饱和度（SaO2）、pH 值、气道湿化满意率、并发症发生率等影响。结果治疗前，湿化氧疗组和常规组的 PaO2、PaCO2、SaO2、pH 值差异无统计学意义（P ＞0．05）；治疗4 h、治疗24 h 后，湿化氧疗组患者的 PaO2、SaO2均高于常规组（P ＜0．05），PaCO2与常规组比较，差异无统计学意义（P ＞0．05）；治疗12 h 后，对两组患者的气道湿化情况进行评价，湿化氧疗组的气道湿化满意度80．00％高于常规组54．29％（P ＜0．05）；湿化氧疗组过度气道湿化0．00％低于常规组的11．43％（P ＜0．05）；治疗过程中，湿化氧疗组的并发症率11．43％低于常规组40．00（P ＜0．05），湿化氧疗组发生生院内获得性肺炎6例（17．14％）低于常规组的14例（40．00％），差异有统计学意义（P ＜0．05）。结论高流量湿化氧疗系统可有效降低气管切开患者院内获得性肺炎的发生率、维持稳定的血气水平。
