摘要
目的:探讨可吸引气管导管在呼吸机相关性肺炎(VAP)治疗中的应用价值。方法:将63例行气管切开、机械通气的患者随机分为观察组32例和对照组31例,均行经皮扩张气管切开术,观察组采用可吸引气管导管行声门下间歇吸引,对照组采用普通气管导管。观察两组每日吸痰次数、吸引分泌物总量、每日刺激性呛咳频次、机械通气时间、机械通气48 h或拔管48 h内的VAP发生率及持续时间差异。结果:观察组每日吸痰次数、刺激性呛咳频次及机械通气时间均少于对照组,而每日吸引分泌物总量高于对照组,差异均有统计学意义(P<0.01)。观察组VAP发生率和VAP持续时间均小于对照组,差异有统计学意义(P<0.05或P<0.01)。结论:对行气管切开、机械通气的患者行可吸引气管导管行声门下间歇吸引,可有效清除气管导管气囊上分泌物,减少呛咳,降低VAP的发生及持续时间,有利于病情恢复。
Objective： To explore the application of suction endotracheal intubation in ventilator associated pneumonia（ VAP）.Methods： 63 patients undergoing tracheotomy and mechanical ventilation via endotracheal intubation were dividedinto observation group（ n = 32） and control group（ n = 31） randomly. After percutaneous dilation tracheostomy,the observation group received intermittent suction endotracheal intubation of subglottic secretion while the control group received common endotracheal intubation. The daily times of sputum suction,amounts of suction secretion,frequency of bucking by irritating,time of mechanical ventilation,incidence of VAP during mechanical ventilation（ within 48 h） and after catheter drawing（ within 48 h） and difference of duration were recorded. Results：The daily times of sputum suction,frequency of cough by irritating and time of mechanical ventilation in observation group were obviously less than those of control group,but amount of suction secretion was higher in observation group than control group（ P 〈0. 01）. Incidence of VAP and its duration in observation group were both obviously less than those of control group（ P 〈0. 05,P〈 0. 01）. Conclusion： For tracheotomy and mechanical ventilation patients giving intermittent suction endotracheal intubation can remove subglottic secretion efficaciously,reduce bucking frequency,and decrease the incidence of VAP and its duration which is in favor of recovery.
