目的:观察封闭式吸痰器在重症监护病房(ICU)机械通气患者中的应用效果。方法:选取本院60例机械通气患者并随机的将其分为对照组和观察组,每组30例。对照组实施一次性普通吸痰管进行吸痰,观察组实施封闭式吸痰器进行吸痰。对两组患者吸痰前后平均动脉压(MAP)、血氧饱和度(SpO_2),吸痰时间、临床效果进行比较。结果:观察组各指标显示吸痰有效率明显优于对照组,差异具有统计学意义(P<0.05);观察组在氧分压(PaO_2)、血二氧化碳(PaCO_2)、舒适度的改变时间等方面比较,差异具有统计学意义(P<0.05)。结论:封闭式吸痰器对ICU机械通气患者吸痰前与吸痰后3 min MAP、SpO_2值无明显影响,具有吸痰时间短,无痰液喷出,避免出现交叉感染的优点。
Objective: To observe the effect of closed sputum aspirator in intensive care unit (ICU) patients with mechanical ventilation. Methods: Sixty patients with mechanical ventilation in our hospital were randomly divided into control group and observation group, 30 cases in each group. Control group to implement a one-time ordinary suction tube for suctioning, the observation group implemented closed suction sputum suction. The mean arterial pressure (MAP), oxygen saturation (SpO_2), suction time and clinical effect before and after sputum aspiration were compared between the two groups. Results: The indexes of the observation group showed that the effective rate of suctioning sputum was significantly better than that of the control group (P <0.05). The changes of PaO_2, PaCO_2 and comfort time in the observation group were statistically significant The difference was statistically significant (P <0.05). Conclusion: The closed sputum aspirator has no significant effect on the MAP and SpO_2 values at 3 min before aspiration and 3h after sputum aspiration in ICU patients with mechanical ventilation. It has the advantages of short suction time, no phlegm and avoiding cross-infection.
