Abstract:
Objective To study the reasonable replacement time for closed suction tube.Methods Totals of 147 patients who had artificial airway for mechanical ventilation and closed suction tube for aspiration of sputum were randomly divided into 3 groups:Group A of 54 cases with replacement time of 24 hours,Group B of 52 cases with replacement time of 72 hours,and Group C of 41 cases with replacement time of 120 hours.Rates of bacterial colonization cultured in closed sputum aspirator tip and incidence rate of VAP were compared between three groups.Results The rate of bacterial colonization cultured in closed sputum aspirator tip in three groups was respectively 63.0％,71.2％ and 100％,and there was statistically significant difference (x2 =6.182,P =0.023).The incidence rate of VAP in three groups was respectively 7.4％,5.7％,4.9％,there was no statistically significant difference (x2 =0.244,P ＞ 0.05).Conclusions Replacement of closed suction tube every 72 hours can ensure patients' safety as well as save the cost.
