摘要
目的探讨引起机械通气相关性肺部感染的相关危险因素。方法对我院行机械通气时间≥48 h的108例患者引起机械通气相关性肺部感染的相关因素进行分析。结果肺部感染率52.78%,最终死亡率24.56%;年龄、吸烟史、呼吸机使用方式、机械通气时间、频繁吸痰、雾化吸入、营养不良、留置胃管、侵入性操作等因素是导致肺部感染的单危险因素;感染病原菌革兰氏阴性菌占58.43%,革兰氏阳性菌占33.71%,真菌占7.87%。结论机械通气患者引起肺部感染危险因素较多,应该尽可能减少相关危险因素的操作。
Objective To explore the related risk factors of mechanical ventilation correlated lung infection. Methods 108 patients were given mechanical ventilation more than 48 hourS and the factors that caused lung infection were analyzed. Results The rate of lung infection was 52. 78% , and final mortality was 24. 56%. The factors that caused lung infection were as follows： age, smoking histo- ry, breathing machine use method, mechanical ventilation time, aspiration of sputum, aerosol inhalation, malnutrition, indwelling gastric tube, and invasive operation. The gram-negative bacteria took up 58.43 % in all of the infection pathogenic bacteria, 33.71% gram-posi- tive bacterium, and 7.87% fungi. Conclusion The risk faetors that cause lung infection for the patients given mechanical ventilation more than 48 hours are various, so it should reduce the operations of related risk factors.
