前馈控制在ICU机械通气呼吸机相关性肺炎风险管理中的应用

Application of feedforward control in risk management of ventilator-associated pneumonia in ICU

目的探讨前馈控制在ICU机械通气呼吸机相关性肺炎(Ventilator-associated pneumonia,VAP)风险管理中的应用。方法选择2021年5月至2022年5月本院收治的ICU机械通气VAP患者104例,随机分为对照组和观察组各52例。对照组行常规护理干预,观察组在对照组基础上行前馈控制护理,两组均干预7d。观察两组临床效果。结果观察组WBC低于对照组,气管拔除及住院时间均短于对照组(P<0.05)。7d后,观察组PaO_(2)、SaO_(2)、TP、ALB、TRF及GCQ各指标评分均高于对照组,PaCO_(2)低于对照组(P<0.05)。结论在ICU机械通气VAP风险管理中应用前馈控制,可有效改善患者各临床指标及血气指标水平,调节营养指标,提高心理舒适度。

Objective To explore the application of feedforward control in risk management of ventilator-associated pneumonia(VAP)in ICU.Methods A total of 104 patients with mechanical ventilation VAP in ICU admitted to our hospital from May 2021 to May 2022 were randomly divided into control group and observation group,with 52 cases each.The control group received routine nursing intervention,and the observation group received feedforward control nursing on the basis of routine nursing in the control group.Both groups received 7 days of intervention.The clinical effects of the two groups were observed.Results The WBC of the observation group was lower than that of the control group,and the time of tracheal extraction and hospitalization were shorter than those of the control group(P<0.05).After 7 days,the scores of PaO_(2),SaO_(2),TP,ALB,TRF and GCQ in the observation group were higher than those in the control group,and PaCO_(2) was lower than that in the control group(P<0.05).Conclusion The application of feedforward control in the risk management of mechanical ventilation VAP in ICU can effectively improve the level of clinical indicators and blood gas indicators,regulate nutritional indicators,and improve psychological comfort.
