高血糖与外科危重病人预后的相关分析

A study on the relation between hyperglycemia in surgical critical patients and prognosis

目的 :通过分析外科危重病人高血糖与机械通气时间、SICU入住时间、医院内感染发生率以及病死率的关系以探讨高血糖与外科危重病人预后的关系。 方法 :采用回顾性研究方法 ,测定 5 72例病人晨起空腹血糖 ,以7.78mmol/L为临界将病人分为两组 ,即A组 (>7.78mmol/L) ;B组 (≤ 7.78mmol/L) ,比较两组的机械通气时间 ,SICU入住时间 ,医院内感染发生率 ,同时统计病人 2 8天内病死率。 结果 :A组的机械通气时间、SICU入住时间和医院内感染发生率均高于B组 (P <0 .0 1)。病人血糖水平与病死率具有相关性 ,血糖水平越高 ,病死率越高(P <0 .0 5 )。 结论 :高血糖与外科危重病人预后密切相关。

Objective: To study the relation between hyperglycemia and mechanical ventilatory time, the days in the intensive care unit,infection rate,mortality . Methods: 572 patients' blood glucose levels in the morning were measured,and divided into two groups by the level of 7.78 mmol/L.The mechanical ventilatory time, days in the intensive care unit,infection rate and mortality were compared between two groups. Results: The mechanical time,stay in ICU and infection rate in the group with blood glucose level below 7.78 mmol/L were significantly less than in the group with blood glucose level above 7.78 mmol/L(P<0.05). Conclusions: It is necessary to control blood glucose in a suitable range,in order to reduce complication and mortality in surgical critically ill patients .
