老年患者心脏直视术后呼吸机相关肺炎探析

摘要

Objective Discussion of open heart surgery in elderly patients with ventilator-associated pneumonia (VAP) of the risk factors and pathogenic characteristics.Methods 44 cases of open heart surgery in our hospital after ventilator associated pneumonia patients were recorded as a group, 42 cases of open heart surgery without ventilator associated pneumonia patients were recorded as group B in the same period, and to explore the pathogenic factors of VAP.Results Compared with group B, Cardiopulmonary bypass time, the confining stay, the postoperative 1h oxygen synthetic index of group A was a signiifcant difference (P<0.05). The oxygenation index in group A after 1 h was (268.73±102.95); The oxygenation index in group B after 1 h was (37.025±153.92).Conclusion According to the VAP condition of the elderly patients with heart disease after operation, the combination with the pathogen and drug sensitivity results rationally use antibiotics and shorten the time of using breathing machine.%目的：探讨老年患者心脏直视术后合并呼吸机相关性肺炎(VAP)的发病危险因素和病原学特点。方法选取我院收治的44例心脏直视手术后发生呼吸机相关肺炎患者记作A组，另选取同期收治的42例心脏直视术未发生呼吸机相关肺炎患者记作B组，探讨VAP致病因素。结果 A组体外循环时间、围术期输血量、机械通气时间、ICU住院天数、术后1 h氧合指数与B组间对比，差异有统计学意义（P＜0.05）， A组术后1 h氧合指数：（268.73±102.95）；B组术后1 h氧合指数：（370.25±153.92）。结论根据老年患者心脏病术后VAP病情，结合病原学及药敏结果合理选用抗生素，缩短使用呼吸机时间。
