【摘要】目的 评价实时动态血糖监测系统(RT-CGMS)与传统间断血糖监测方法(IGM)在危重症胰岛素强化治疗(IIT)中的作用是否存在差异,以探讨RT-CGMS在危重症强化降低血糖治疗中的意义。方法 系统性检索中文、西文文献数据库中的相关临床随机对照试验(RCT),应用Review Manager 5.2软件进行荟萃分析。评价指标包括:低血糖事件发生率、平均血糖水平、血糖达标时间比例、短期病死率等。结果 共有6篇文献,总计531例患者纳入本次研究。平均血糖水平合并SMD=-0.21(95% SMD:-0.43~0.01,P=0.07);血糖达标比例时间合并SMD=0.20(95% SMD:-0.09~0.49,P=0.18);低血糖事件发生率合并OR=0.20(95% CI:0.09~0.43,P<0.01);短期病死率合并OR=0.35(95% CI:0.14~0.89,P=0.03)。结论 危重症强化胰岛素治疗(IIT)过程中应用RT-CGMS可明显减少低血糖事件的发生率,但RT-CGMS在保持血糖于理想水平方面比较传统间断血糖监测(IGM)未见明显优势。

【Abstract】Objective To evaluate the value of real time continuous blood glucose monitoring system(RT-CGMS) versus intermittent blood glucose monitoring(IGM) in the critically ill patients under intensive insulin therapy (IIT).Methods A systematic searching randomized and controlled trials (RCT) in databases was performed for meta-analysis by Review Manager 5.2 software. Outcomes were hypoglycemia episode, alteration of mean blood glucose level, the percentage of time at a blood glucose level within optimal target range, and the early mortalities. Results Six studies,totally 531 patients, were included in this meta-analysis. The pooled SMD of mean blood glucose level was =-0.21 (95%SMD:-0.43-0.01,P=0.07).The pooled SMD of percentage of time at a blood glucose level within optimal target range was 0.20 (95%SMD:-0.09-0.49,P=0.18). The pooled OR of hypoglycemia episode frequency was 0.20 (95%CI:0.09-0.43,P<0.01). The pooled OR of early mortalities was 0.35 (95%CI:0.14-0.89,P=0.03). Conclusions In critically ill patients under the intensive insulin therapy, RT-CGMS had obvious beneficial effect on reducing hypoglycemic events. RT-CGMS had no obvious beneficial effect on keeping blood glucose level within optimal target range.

危重癥患者发生高血糖的几率较高,严格控制血糖水平可以改善危重症患者的预后,降低病死率。重症医学界对危重症患者高血糖的危害以及强化降低血糖治疗的重要性已经达成共识,但血糖控制于何种水平一直存在较大争议,目前主要观点认为应将血糖水平控制于≤180 mg/L(10 mmol/L),并尽量避免低血糖的发生[1]。重症监护病房常用的血糖控制方法为强化胰岛素治疗(intensive insulin therapy,IIT),并通过每间隔1~2 h监测指尖血糖或动脉血糖的方法了解患者血糖变化趋势及调整胰岛素的使用剂量,但仍时有低血糖情况的发生[2]。实时动态血糖监测系统(real time continuous glucose monitoring system,RT-CGMS)通过在患者皮下植入监测探头,实时监测患者血糖水平,及时将所得血糖数值显示于屏幕上,并可通过设置血糖极端值报警以提示高血糖和低血糖的发生,在糖尿病患者特别是1型糖尿病患者中的使用已得到广泛认可[3-4]。……
