Influence of air impact methods clearing out the subballonet secretion on ventilator-associated pneumonia

Objective To explore the effect of air impact method clearing out the subballonet secretion on the prevention of ventilator-associated pneumonia(VAP) for ventilation patients.Methods 108 cases from ICU who received mechanical ventilation were selected.Patients were divided into the observation group and control group according to odd and even numbers,54 cases in each group.The control group was received conventional airway management,and the observation group received air impact method on the basis of conventional management Results of blood gas analysis,vital signs,occurrence time of VAP,total incidence of VAP,mortality,OB,positive results during mechanical ventilation were observed.Results Occurrence time of VAP for observation group and control group respectively were (14.1 ± 5.2) d and (8.9 ± 3.8) d.VAP incidence in 1 week for observation group and control group respectively were 7.4% (4/54) and 27.8% (15/54).Test positive result of secretion OB for observation group and control group respectively were 16.7% (9/54) and 3.7% (2/54).Total Incidence of VAP for observation group and control group respectively were 33.3% and 37.0%.Differences of occurrence time of VAP,VAP incidence in 1 week and test positive result of secretion OB for two groups were statistically significant (t =5.933,x2 =7.728,4.960,all P ＜ 0.05).Differences of results of blood gas analysis,vital signs,total incidence of VAP,mortality for two groups had not statistically significant.Conclusion Air impact method cleating out the subballonet secretion is simple and safe.Occurrence time of VAP was delayed.Incidence of VAP in one week decreases.,which creates opportunity for rescuing patients.
