老年急性假性肠梗阻患者医院感染特点与危险因素

目的 探讨老年急性假性肠梗阻患者发生医院感染的特点及危险因素.方法 回顾性分析395例急性假性肠梗阻患者的病历资料,对其医院感染的特点及危险因素进行总结.结果 老年组154例患者发生医院感染45例,感染率为29.2％,非老年组241例,发生医院感染17例,感染率为7.1％,老年组的医院感染率明显高于非老年组(P＜0.05)；感染部位主要为呼吸道、消化道、泌尿道等；医院感染的发生危险因素与患者年龄、住院天数、合并基础疾病、侵入性操作、使用抗菌药物有关；感染病原菌以革兰阴性菌为主,占62.9％.结论 老年急性假性肠梗阻患者医院感染的发生率高,医务人员应高度重视,控制危险,降低医院感染率.

Risk factors for nosocomial infections in aged patients with acute intestinal pseudo-obstruction

OBJECTIVE To study the characteristics of nosocomial infections in aged patients with acute intestinal pseudo-obstruction and risk factors.METHODS A retrospective study of the clinical data of nosocomial infections in 395 inpatients with acute intestinal pseudo-obstruction was conducted,the characteristics and the risk factors were summarized.RESULTS Nosocomial infections occurred in 45 of 154 aged patients with the incidence of 29.2%,and nosocomial infections occurred in 17 of 241 patients of the younger age-group with the incidence of 7.1%,the incidence of nosocomial infections in aged patients was higher than in younger aged group(P<0.05);the predominant infected sites were the respiratory tract,gastrointestinal tract,and urinary tract;the age of the patient,hospitalization duration,underlying disease,invasive operations,and use of antibiotics were the risk factors for nosocomial infections;gram-negative bacteria were predominant pathogens causing infections,accounting for 62.9%.CONCLUSION The incidence of nosocomial infections in the aged patients with acute intestinal pseudo-obstruction is high,the medical staff need to attach great importance to the control of the risk factors so as to decrease the incidence of nosocomial infections.
