地震创伤患者感染流行病学分析

Epidemiological analysis on infections in patients with earthquake injury

摘要:

目的探讨地震创伤患者感染的特征及其影响因素。方法对某院2008年5月16日—8月20日收治的140例地震伤员相关感染情况进行前瞻性调查分析。结果140例地震伤员感染的发生率为40.71%（57/140），其中医院感染发生率为28.57%(40/140)。分离到的88株感染病原菌中，以革兰阴性菌为主（占57.09%）；从伤口分离出5株厌氧菌。创伤AIS-ISS分值与感染有密切关系，ISS分值越高，感染率也越高（χ2=13.12， P＜0.05）。结论感染是地震创伤后的常见并发症，认真对伤员进行地震伤情分值计算以预测医院感染的发生，采取积极有效的预防和干预措施控制创伤感染非常必要。

Abstract:

ObjectiveTo study the characteristics and risk factors of infections in patients with earthquake injury. MethodsInfections from 140 patients who were injured in Wenchuan earthquake and admitted in a hospital from May 16 to August 20, 2008 were analyzed by prospective study. ResultsThe infection rate of 140 patients was 40.71% (57/140) and nosocomial infection rate was 28.57%(40/140) in patients with earthquake injury. Gramnegative bacilli were  the main pathogens among 88 strains of pathogens in infection, which accounting for 57.09%; 5 strains of anaerobic bacteria were isolated from wound.  Infection had a significant correlation with AISISS score, the higher  AIS-ISS score was, the higher rates of infections were. ConclusionInfection is a common complication of earthquake injury, it is necessary to analyze AISISS score for predicting the occurrence of nosocomial infection, and take effective measures to prevent and control traumatic infection.
