摘　　要：目的观察持续声门下吸引（CASS）对呼吸机相关性肺炎（VAP）患者的影响。方法收集150例机械通气患者，记录患者的基本情况，按随机数字表法将其分为对照组（70例）和CASS组（80例）。对照组采用常规预防VAP的方法，CASS组在对照组的基础上联合CASS治疗。比较两组患者的基本情况及VAP发生率。结果两组性别构成、年龄、急性生理学和慢性健康状况Ⅱ评分、近期应用抗生素、气囊压、人住ICU时间、住院时间和病死率比较差异均无统计学意义（P〉0．05），但CASS组呼吸机治疗时间明显短于对照组[（5．2±1．4）d比（7．8±1．2）d，P=0．02]，VAP发生率明显低于对照组[22．5％（18／80）比32．9％（23／70），P=0．04]。结论CASS可降低VAP发生率，缩短呼吸机治疗时间。Objective To observe the infection of continuous aspiration of subglottic secretion （CASS） for patients with ventilator associated pneumonia （VAP）. Methods One hundred and fifty VAP patients under mechanical ventilation whose basical information were recorded were divided into two groups by random digits table method： control group （70 cases） and CASS group （80 cases）. Conventional VAP prevention was taken in control group and CASS group, while CASS therapy was added to CASS group. Results Sex, age, acute physiology and chronic health-evaluation I] score, recent antibiotics usage, air pressure, time in ICU, hospital stay and mortality rate of two groups had no statistical significance （P 〉 0.05 ）. The time of ventilator treatment of CASS group was obviously shorter than that of control group [ （5.2± 1.4） d vs. （7,8±1.2） d,P= 0.021, and VAP incidence was lower than that of control group[22.5%（18/80） vs. 32.9% （23/70）,P = 0.04 ]. Conclusion CASS could reduce the incidence of VAP and short the time of ventilator treatment.
