血糖不稳定指数在评估重症监护患者预后中的价值分析

Glycemic Instability Index in the Assessment of Intensive Care Patients Prognosis Analysis

目的分析血糖不稳定指数在评估重症监护患者预后中的价值。方法选取该院收治的80例重症患者为研究对象,观察记录这些患者在24h内每隔2h的血糖变化情况,并计算血糖不稳定指数、最大血糖波动幅度、标准差、平均值、变异系数以及日内平均血糖波动幅度,观察患者1个月后的转归情况,运用ROC曲线评估患者血糖不稳定指数和预后情况的相关性。结果 30例患者死亡,总病死率为37.5%,血糖不稳定指数ROC曲线下的面积优于最大血糖波动幅度、标准差、平均值、变异系数以及日内平均血糖波动幅度ROC曲线下面的面积。血糖不稳定指数与重症患者APACHEⅡ评分有显著的相关性。结论重症监护患者入院24h内,血糖不稳定指数与患者预后情况有明显的相关性。

Objective To analysis of glycemic instability index in the assessment of intensive care patients prognosis. Methods From 2010 January to 2011 January in our hospital80 cases of critically ill patients as the object of study, observation records of these patients within 24 hours every 2 hours blood glucose changes, and calculate glycemic instability index, blood glucose fluctuations, standard deviation, average value, variance coefficient and days of average blood glucose fluctuations, patients were observed after one month outcomes, using ROC curve in evaluating patients with unstable blood sugar index and prognosis correlation. Results 30 patients died, the fatality rate was 37.5%, unstable blood sugar index area under the ROC curve is better than the maximum blood glucose fluctuations, standard deviation, average value, variance coefficient and days average blood glucose fluctuations of ROC curves following area. Glycemic instability index and severe patients there was a significant correlation between the score of APACHE Ⅱ. Conclusion Intensive care patients within 24 hours of admission, unstable blood sugar index and prognosis in patients with significant correlation.
