【摘要】 目的 评价气流冲击法联合口腔冲洗在重症监护室（ICU）气管插管患者中的临床应用效果。方法 选取2022年1月—2023年11月在日照市人民医院ICU行气管插管的110例患者为研究对象，采用随机数表法分为对照组和观察组，各55例。对照组进行口腔冲洗，观察组先行气流冲击法清除气囊上滞留物后再进行口腔冲洗。比较两组患者呼吸机相关性肺炎（VAP）发生率、气管插管时间、入住ICU时间及血气指标。结果 观察组VAP发生率低于对照组，差异有统计学意义（P<0.05）。观察组气管插管时间、入住ICU时间均短于对照组，差异有统计学意义（P<0.05）。干预后，观察组动脉血二氧化碳分压低于对照组，动脉血氧分压高于对照组，差异有统计学意义（P<0.05）。结论 气流冲击法联合口腔冲洗能有效清除口腔及声门下-气囊上的滞留物，减少细菌移位，有效降低VAP发生率，缩短气管插管时间，缩短患者ICU入住时间，并可改善血气指标。更多还原

【Abstract】 Objective To evaluate the clinical application effect of airflow impact method combined with oral irrigation in patients with tracheal intubation in the intensive care unit(ICU). Methods A total of 110 patients who underwent tracheal intubation in the ICU of Rizhao People’s Hospital from January 2022 to November 2023 were selected as the research subjects. They were randomly divided into a control group and an observation group, with 55 cases in each group, by the random number table method. The control group had oral rinsing, while the observation group had oral rinsing. First, the airflow impact method was used to remove the retained substances on the airbag, and then oral rinsing was performed. The incidence of ventilator-associated pneumonia(VAP), the time of tracheal intubation, the length of stay in the ICU and the blood gas indicators were compared between the two groups of patients. Results The incidence of VAP in the observation group was lower than that in the control group, and the difference was statistically significant(P<0.05). The tracheal intubation time and ICU stay time in the observation group were shorter than those in the control group, and the difference was statistically significant(P<0.05).After the intervention, the arterial blood carbon dioxide content in the observation group was lower than that in the control group, and the arterial blood oxygen partial pressure in the observation group was higher than that in the control group. The difference was statistically significant(P<0.05). Conclusion The air flow impact method combined with oral irrigation can eff ectively remove the retained substances in the oral cavity and on the subtonal-air sac, reduce bacterial translocation, effectively lower the incidence of VAP, shorten the time of tracheal intubation, shorten the length of ICU stay for patients, and improve blood gas indicators.更多还原
