机械通气对高龄PICC置管患者发生感染的影响

目的了解高龄机械通气患者经PICC置管发生导管相关性感染的发生率及特点。方法对ICU机械通气高龄患者51例，未行机械通气高龄患者81例PICC置管情况进行回顾性分析。结果51例机械通气高龄患者置管70次，8例患者发生CRI15次。其中4例机械通气高龄患者痰培养结果与CRI的病原体相同。81例未行机械通气者置管88次，2例患者发生CRI3次。结论高龄患者CRI与置管部位无关，与导管留置时间较长和气管切开次数较多有关。尤其与长期机械通气者常以革兰阳性球菌和真菌感染为主要的病原菌有关。

Objective To understand the occurrence of catheter-related infection incidence and characteristics of elderly patients with mechanical ventilation PICC catheter.Methods 51 cases of ICU mechanical ventilation in elderly patients did not undergo mechanical ventilation in 81 cases of elderly patients with PICC catheter were retrospectively analyzed.Results 51 cases of elderly patients with mechanical ventilation catheter 70 cases,eight cases of patients with CRI 15 times.Sputum culture results of four cases of mechanical ventilation in elderly patients with CRI pathogens.81 cases of mechanical ventilation catheter 88 cases occurred in two patients CRI 3 times.Conclusion elderly patients with CRI and catheter site regardless of the number of tracheal incision with the catheter longer and more relevance.Especially with long-term mechanical ventilation often Gram-positive cocci, and fungal infections is mainly related to the pathogen.
