摘　　要：目的探讨动态血糖监测系统常见报警原因及安装使用中易出现的问题。方法 2007年7月—2009年10月来我院就诊的血糖控制不良或低血糖行动态血糖监测者共140例,对动态血糖监测图像进行回顾性分析,总结动态血糖监测系统报警原因。结果 42例患者动态血糖监测系统发生报警,共79次。其中校准错误报警42次(占53.2%),断开报警31次(占39.2%),探头信号不在正常范围报警4次(占5.1%),噪音报警2次(占2.5%),未发生电池电量不足报警。2例患者在监测中无意中关机导致部分图像丢失;1例在安装后误操作将血糖单位mmol/L改为mg/ml导致数据丢失;1例将设置中的日期设置改变导致数据丢失;1例未清除前一个患者的监测图像,导致本次监测图像与前一患者的图像相连;3例探头脱出;2例安装24 h后信号波动仍较大需更换探头。结论熟练掌握动态血糖监测系统的安装程序,及时发现和处理报警是保证动态血糖监测过程顺利完成及监测数据完整准确的关键。Objective To explore the common reasons for alarms of continuous glucose monitoring system（CGMS） and common problems in its installation and application.Methods The CGMS data were retrospectively analyzed in 140 patients with poor-controlled glucose or hypoglycemia receiving CGMS from July 2007 to October 2009.Results Alarms of CGMS occurred in 42 patients,altogether 79,including 42 calibration error alarms（53.2%）,31 disconnecting（39.2%）,4 with probe signals beyond normal range（5.1%）,2 noise（2.5%）,no alarms due to low electric quantity in batteries.Two patients turned off CGMS unintentionally to cause some image loss,1 modified the glucose unit from mmol/L to mg/ml after installation to lead to data loss,1 changed the date setup to lead to data loss,1 failed to clear the images of former user to lead to his images connecting with those of the former,3 had prolapsed probes,2 needed to change probes due to large signal fluctuation 24 h after installation.Conclusion Master of CGMS installation,timely finding and dealing with alarms ensure a smooth CGMS and complete and accurate data.
