2型糖尿病患者血糖水平对院内感染发生率的影响

目的：观察2型糖尿病患者血糖水平与院内感染发生率的关系。方法：对我院2009年12月-2010年12月住院的42例2型糖尿病患者进行院内感染回顾性分析。结果：42例2型糖尿病患者发生院内感染10例次（部分为反复发作）,感染发生率23.8%,显著高于我国平均院内感染发生率（8.4%,P〈0.05）。感染部位以下呼吸道最常见,其次为泌尿道和消化道。在住院时间合并慢性基础疾病,年龄,侵入性治疗无明显差异的情况下,长期血糖控制组（HbA1c〈6.5%）感染发生率13.3%、血糖未控制组（HbA1c≥6.5%）为50.0%,两组比较差异有统计学意义（P〈0.05）,血糖控制组患者低血糖事件发生率5.2%,血糖未控制组发生率5.0%,差异无统计学意义（P〉0.05）。结论：严格控制血糖可减少老年护理院2型糖尿病患者院内感染发生率,减少由感染引起的死亡。

The effect of the blood glucose level of the elderly diabetes patients on the infection occurrence in the hospital

Objective:To observe the correlation between blood glucose level and incidence of infection for type II diabetes patients in the hospital.Methods:42 cases of type II diabetes patients were Analyzed,who were treated at our hospital from Dec 2009 to Dec 2010.Results:10 incidences of infection(including repetitive cases) among the 42 type II diabetes patients.Infection rate is 23.8%.This is much higher than the national average inpatient infection rate(8.4% P<0.05).The most common site of infection is the respiratory tract,follwed by urinary tract and digestive tract.If we control duration of hospitalization,presence of basic chronic disease,age and the difference in effectiveness of intrusive treatment,infection rate in the glycosylated hemoglobin A1c controlled group(HbA1c<6.5%) was 13.3% while in the uncontrolled group it is 50.0%,which is significantly lower in controlled group than in uncontrolled group(P<0.05).The incidence rate of low glucose in the controlled group is 5.2% and the rate in the uncontrolled group is 5.0%(P>0.05)-no significant difference.Conclusion:Strict control of blood glucose level can decrease the infection rate of type II diabetes patients in senior care hospitals,and decrease the incidence of complications.
