综合干预模式在ICU患者中的应用对VAP的预防及对呼吸功能、血气指标的影响

The application of comprehensive intervention mode in ICU patients and its influence on VAP prevention,respiratory function and blood gas indexes

目的探讨综合干预模式在ICU患者中应用对呼吸机相关性肺炎(VAP)的预防及对呼吸功能、血气指标的影响.方法于2021年7月-2023年8月在入住本院ICU的患者中选取72例,按随机数字表法分成两组,对照组36例行常规护理,观察组36例通过综合干预模式展开护理,对比两组的炎性因子与肺部感染情况、VAP发生情况、呼吸功能及血气指标.结果观察组护理后的血清C反应蛋白(CRP)、降钙素原(PCT)水平及临床肺部感染评分(CPIS)均比对照组低(P<0.05);观察组的VAP发生率是5.56%,比对照组的22.22%低(P<0.05);观察组护理后的氧合指数比对照组高,呼吸次数、浅快呼吸指数比对照组低(P<0.05);观察组护理后的动脉血氧分压(PaO_(2))、动脉血氧饱和度(SaO_(2))比对照组高,二氧化碳分压(PaCO_(2))水平比对照组低(P<0.05).结论综合干预模式可降低ICU患者VAP风险,有效预防VAP的发生,并进一步改善其呼吸功能与气血指标.

Objective To explore the effect of comprehensive intervention mode on the prevention of ventilator associated pneumonia(VAP)and respiratory function and blood gas index in ICU patients.Methods From July 2021 to August 2023,72 patients were selected from those admitted to the ICU of our hospital and divided into two groups according to the random number table method.36 patients in the control group received routine nursing care,36 patients in the observation group were nursing through comprehensive intervention mode,and compared the inflammatory factors and pulmonary infection,VAP occurrence,respiratory function and blood gas indicators of the two groups.Results After nursing,the levels of serum C-reactive protein(CRP),procalcitonin(PCT)and clinical pulmonary infection score(CPIS)in observation group were lower than those in control group(P<0.05).The incidence of VAP in observation group was 5.56%,which was lower than 22.22%in control group(P<0.05).After nursing,the oxygenation index of the observation group was increased,the number of breaths and shallow and fast breathing index were decreased compared with the control group(P<0.05).The partial pressure of oxygen(PaO_(2))and saturation of oxygen(SaO_(2))in the observation group were higher than those in the control group,and the level of partial pressure of carbon dioxide(PaCO_(2))was lower than that in the control group(P<0.05).Conclusion The comprehensive intervention model can reduce the risk of VAP in ICU patients,effectively prevent the occurrence of VAP,as well as further improve their respiratory function and blood indicators.
