Abstract

In adult patients with mechanical ventilation, more frequent ventilator circuit tubing replacement may increase the odds of ventilator-associated pneumonia, but the findings are imprecise. In pediatric patients with mechanical ventilation, more frequent and less frequent intervals of ventilator circuit tubing replacement may result in a similar risk of ventilator-associated pneumonia, all-cause mortality, and ventilator-associated pneumonia mortality, and similar durations of mechanical ventilation and hospital stay. For preterm neonates, children, and adult patients, it is recommended to replace the ventilator circuit tubing if it is visibly soiled, not functioning properly, or as recommended in the manufacturer's instructions. We did not find any guidelines about fixed versus nonfixed ventilator circuit tubing replacement.

呼吸机回路管更换时机
& # x0D;在机械通气的成年患者中,更频繁地更换呼吸机回路管可能会增加呼吸机相关性肺炎的几率,但研究结果并不精确。 在使用机械通气的儿科患者中,更频繁和更不频繁的呼吸机回路管更换间隔可能导致呼吸机相关肺炎、全因死亡率和呼吸机相关肺炎死亡率的风险相似,并且机械通气和住院时间相似。 对于早产儿、儿童和成人患者,如果呼吸机回路管明显被污染,不能正常工作,或按照制造商的说明建议,建议更换呼吸机回路管。我们没有发现任何关于固定与非固定呼吸机回路管更换的指南。
