Abstract:
Objective To investigate the effect of early airway bundle intervention on prevention ventilator-associated pneumonia(VAP) in ICU patients.Methods One hundred and twenty-eight patients with invasive mechanical ventilation in ICU were randomly divided into the control group (64 cases) and observation group(64 cases).Patients in the control group were given conventional airway intervention,and in the observation group were given airway bundle intervention within 4 h including dumping of condensed water in tubing of breathing machine in time,keeping pressure of artificial airbags from 20 to 30 cm H2 O,chest physical therapy 2 h/time,continuous aspiration of subglottic secretion,using moisture exchanger in breathing machine,and mouth rinse by chlorhexidlne 4 h/time.Incidence of VAP,duration of mechanical ventilation,duration of stay in the ICU and mortality within 28-day were recorded.Clinical Pulmonary Infection Score (CPIS) and APACHE Ⅱ at 0,3rd,5th,7th,14th day were recorded respectively.Results The incidence of VAP,duration of mechanical ventilationand duration of stay in the ICU in observation group were 18.75％,(6.26 ± 2.89) d,(11.88 ± 3.97) d respectively,lower than those in control group (35.94％,(10.54 ± 4.36) d,(16.55 ±5.22) d)),and the differences were significant (x2=4.758,t =6.546,t =6.546,P＜0.05 orP＜0.01).At 3rd,5th,7th,14th day after diagnosed VAP,CPIS of patients with confirmed VAP in observation group were 7.01 ±2.24,5.67 ±2.14,4.36 ± 1.44,2.75 ± 1.37 respectively,lower than those in control group(8.74 ± 2.33,7.51 ± 2.27,6.95 ± 2.98,6.53 ± 2.88,and the differences were significant (Finter group =27.22,P ＜ 0.001 ; Fbetween group =29.41,P ＜ 0.001 ; Finteraction =4.35.P ＜ 0.01).APACHE Ⅱ were 17.02 ± 7.06,15.01 ± 6.06,12.40 ± 4.17,8.40 ± 2.57 respectively,significant lower than those in control group ((22.48 ±7.31,19.67 ± 7.14,16.13 ± 5.33,13.10 ± 4.93),and the differences were significant (Finter group =47.43,P ＜ 0.001 ; Fbetween group =45.36,P ＜ 0.001 ; Finteraction =4.25,P ＜ 0.01).Conclusion Early using airway bundle interventions on ICU patients can reduce the incidence of VAP,improve the condition and prognosis.
