目的 探讨清除气管导管气囊上滞留物的最佳时间.方法 将94例气管插管行机械通气治疗48 h以上患者随机分为A、B、C三组,分别每4h、8h、12h进行气囊上滞留物清除.结果 4h组和8h组呼吸机相关性肺炎发生率、病死率、机械通气时间均低于12 h组(P＜0.05),4h组和8h组比较,各项指标差异无统计学意义(P＞0.05).结论 8h清除气管导管气囊上滞留物能明显减少呼吸机相关性肺炎的发生,缩短机械通气时间,降低病死率,节约成本,为最佳清除时间.%Objective To explore the best time of the subglottic secretion drainage. Methods A total of 94 patients with endotracheal intubation and mechanical ventilation for over 48 hours were randomly divided into three groups of A,B and C. And 4 hours,8 hours and 12 hours intermittent subglottic secretion drainage were done respectively in group A,B and C. Results The incidence of ventilator - associated pneumonia,mortality,duration of mechanical ventilation in group 4 hours and group 8 hours were lower than those of 12 hours group (P < 0. 05). The indicators were no significant difference between group 4 hours and group 8 hours (P >0. 05). Conclusion The 8 hours intermittent subglottic secretion drainage can significantly reduce the incidence of ventilator - associated pneumonia,minimize the duration of mechanical ventilation and mortality and save the costs,thus it is the best clearing time.
