声门下间歇吸痰在预防危重症患者呼吸机相关性肺炎的临床疗效评价

Clinical Evaluation of Subglottic Intermittent Sputum Aspiration in the Prevention of Ventilator-associated Pneumonia in Critically Ill Patients

目的:观察声门下间歇吸痰在预防危重症患者呼吸机相关性肺炎的临床疗效。方法:某院2019年2月~2020年2月收治的70例危重症患者为研究对象,按照是否开展声门下间歇吸痰将患者分为对照组(未开展声门下间歇吸痰而行常规吸痰)与实验组(声门下间歇吸痰)各35例,比较两组患者治疗效果。结果:实验组吸痰治疗后30min氧分压(PaO_(2))、二氧化碳分压(PaCO_(2))、血氧饱和度(SaO_(2))等血气分析数值均优于对照组,数据差异明显(P<0.05);实验组患者呼吸机相关性肺炎发生率(2.86%)低于对照组,数据差异明显(P<0.05);实验组患者吸痰后Kolcaba舒适状况量表评分显著高于对照组,差异明显(P<0.05)。结论:危重症患者声门下间歇吸痰可有效降低呼吸机相关性肺炎发生率。

Objective:To observe the clinical efficacy of subglottic intermittent sputum aspiration in the prevention of ventilator-associated pneumonia in critically ill patients.Methods:70 critically ill patients in a hospital from February 2019 to February 2020 were selected as the research objects.The patients were divided into control group(35 cases,routine sputum aspiration without intermittent subglottic suction)and experimental group(35 cases,intermittent suction under glottis)according to whether to carry out intermittent suction under glottis.Results:The blood gas analysis values of PaO_(2),PaCO_(2) and SaO_(2) in the experimental group were better than those in the control group at 30 min after sputum suction treatment,with significant difference(P<0.05).The incidence of ventilator-associated pneumonia in the experimental group(2.86%)was lower than that in the control group(P<0.05).The score of Kolcaba Comfort Scale in the experimental group was significantly higher than that in the control group(P<0.05).Conclusion:Intermittent sputum aspiration under glottis can effectively reduce the incidence of ventilator-associated pneumonia in critically ill patients.
