ABSTRACT
Objective To explore the application value of chlorhexidine combined with disposable combined type sputum suction tube in ventilator-associated pneumonia(VAP).To provide an effective method for prevention and control of hospital infection in ICU.Methods 104 patients with mechanical ventilation were randomly divided into the observation group(55 cases) and control group(49 cases).During the period of hospitalization,the incidence rates of oral infection and VAP of the two groups were observed.At the time of admission and in-hospital,clinical pulmonary infection scores (CPIS) of the two groups were evaluated.Results Oral herpes,ulcer incidence rates of the observation group were 3.64%,9.09%,which were lower than the control group,the differences were statistically significant (χ2 =4.802,4.494,all P<0.05).After 3 days and 7 days of mechanical ventilation,VAP incidence rates of the observation group were 3.64%,12.73%,which were lower than the control group,the differences were statisti-cally significant (χ2 =5.945,4.037,all P<0.05).After 3 days and 7 days of mechanical ventilation,the results of CPIS of the observation group were (4.94 ±0.76) points,(5.29 ±0.91) points,which were lower than the control group,the differences were statistically significant (t=3.812,3.295,all P<0.05).Conclusion The medical care of chlorhexidine combined with disposable combined type sputum suction tube showes significant effect on patients with mechanical ventilation,has high value in clinical application.
