摘　　要：目的探讨密闭式吸痰管腔冲洗器在人工气道行机械通气的危重症患者中的应用效果。方法选取2021年1月至2021年12月在本院接受人工气道机械通气治疗的患者84例作为对照组,吸痰时采用传统冲洗法,即使用注射器抽吸生理盐水连接密闭式吸痰管的冲水孔进行操作。选取2022年1月至2022年12月在本院接受人工气道行机械通气治疗的患者84例作为观察组,使用密闭式吸痰管腔冲洗器进行冲洗。比较两组在气液喷溅滴漏污染率、单次冲洗人工气道吸引管腔耗时、潮气量方面的差异。结果观察组在操作过程中未发生气液喷溅滴漏污染,而对照组气液喷溅滴漏污染率为40.48%。两组比较差异具有统计学意义(P<0.05);观察组单次冲洗人工气道吸引管腔耗时少于对照组,分别为(7.45±1.48)s和(27.46±5.08)s,两组比较差异具有统计学意义(P<0.05);观察组冲洗前的潮气量高于对照组,分别为(0.436±0.053)L和(0.351±0.060)L,两组比较差异具有统计学意义(P<0.05)。结论密闭式吸痰管腔冲洗器的应用有效避免了冲洗操作时的气液喷溅滴漏现象,符合无菌操作原则,降低了交叉感染的风险,提高了工作效率,并有助于保持呼吸机治疗的稳定性。Objective To explore the application effect of the closed suction catheter cavity irrigator in critically ill patients with artificial airway undergoing mechanical ventilation.Methods Using a convenience sampling method,84 patients who received mechanical ventilation treatment through an artificial airway in our department from January 2021 to December 2021 were selected as the control group.The traditional irrigation method was used for suction,which involved using a syringe to draw up physiological saline and connecting it to the water inlet of the closed suction catheter.From January 2022 to December 2022,84 patients who received mechanical ventilation treatment through an artificial airway in our department were selected as the experimental group,and the closed suction catheter cavity irrigator was used for irrigation.The differences in liquid splash and leakage pollution rate,time consumed for single suction of the artificial airway,and tidal volume between the two groups were compared.Results No liquid splash and leakage pollution occurred during the operation in the experimental group,while the pollution rate was 40.48%in the control group.The difference between the two groups was statistically significant(P<0.05).The time consumed for single suction of the artificial airway in the experimental group was less than that in the control group,with averages of(7.45±1.48)seconds and(27.46±5.08)seconds,respectively.The difference between the two groups was statistically significant(P<0.05).The tidal volume before irrigation in the experimental group was higher than that in the control group,with averages of(0.436±0.053)L and(0.351±0.060)L,respectively.The difference between the two groups was statistically significant(P<0.05).Conclusion The application of the closed suction catheter cavity irrigator effectively avoids the phenomenon of liquid splash and leakage during the irrigation operation,complys with the principles of aseptic operation,reduces the risk of crossinfection,improves work efficiency,and help
