即使没有糖尿病病史,危重病患者也常出现血糖升高。应激在危重病患者高血糖的发生过程中起重要作用。研究表明,高血糖与患者不良预后相关。采用强化胰岛素治疗严格控制血糖可降低患者并发症发生率和病死率,显示出良好的应用前景,但在临床实践中,也面临一些问题。 Even without a history of diabetes, critically ill patients often have elevated blood sugar. Stress plays an important role in the pathogenesis of hyperglycemia in critically ill patients. Studies have shown that hyperglycemia is associated with poor prognosis in patients. Using intensive insulin therapy to strictly control blood sugar can reduce the incidence of complication and mortality in patients, showing a good prospect, but in clinical practice, but also face some problems.
