Impact on Ventilator-associated Pneumonia with Different Intervals of Ventilator Circuit Exchange
摘要
The purpose of this prospective study was to explore different methods of ventilator circuit change on lowering ventilator-associated pneumonia (VAP) rates in a regional teaching hospital. Over a 54-week period, 136 patients with the use of ventilators in an intensive care unit were assigned to two groups. Sixty-seven patients in the group 1 received circuit changes once a week (7d), while 69 patients in the group 2 received circuit changes three times a week (2-3d). The effects of APACHE 11 score, Glasgow coma scale, shock, vital signs, biophysical values, and the use of antibiotics and nebulizers were investigated. The results showed that the overall VAP of 136 patients was 15.44%: 16.42% in the group 1 and 14.49% in the group 2. On average, there were 11.64 VAP per 1000 ventilator days of 136 patients: 12.54 in the group 1 and 10.79 in the group 2. There was no significant difference between the two groups. Yet, pulse rate, respiratory rate, systolic pressure, pulmonary infection, respiratory failure, shock, 1St day APACHE Ii score after ventilator therapy within 24hours, and nebulizer therapy were found as significant factors related to the VAP (P＜0.05). Ventilator circuit can be safely changed at weekly intervals to save the cost.
