Diabetes Care:血糖实时连续监测作为第五生命体征在临床中的应用

2020-11-04 MedSci原创 MedSci原创

RT-CGM有可能通过对这些患者进行早期干预控制,从而改善TIR、平均血糖和高血糖。

在医院里,血糖失控很常见。住院病人血糖控制不良的原因是多因素的,包括急性病对血糖的影响(应激性高血糖症)、食欲和/或营养状况的波动、类固醇的使用和/或其他药物的变化、不可预测的检查和程序等待时间等。目前医院血糖管理的标准是即时(POC)检测;然而,连续血糖监测(CGM)回顾性研究显示POC检测血糖会漏检33%的高血糖和高达90%的低血糖事件。近日,Diabetes Care上发表的一项新研究在医院(非ICU)进行了实时CGM (RT-CGM)和POC的随机对照试验。

共有110名非重症监护病房的2型糖尿病(T2D)患者接受了RT-CGM监测或普通监测(UC)。RT-CGM数据从床边无线传输。医院遥测监测RT-CGM数据,并通知床边护理血糖警报和趋势。干预措施采用标准化方案。

参与者年龄从30岁到89岁(平均61.94[13.22]);大多数是女性(54.5%)和西班牙裔(74.3%)。在基线特征、CGM持续时间、住院期间使用影响血糖的药物或住院时间(Ps)方面,组间无显著差异。0.31)。在POC后5min内获得的CGM值对POC值具有很高的预测性(P,0.001)。

研究数据表明,RT- CGM和用于急性高/低血糖RT管理的标准化方案改善了平均血糖和TIR,而没有增加T2D患者发生低血糖的时间百分比。虽然RT-CGM组中经历一次或多次低血糖事件的参与者略多,但使用RT-CGM组每个参与者的事件数更低,且这些事件持续时间更短。先前的研究表明CGM与POC有良好的相关性,通常在不进行任何干预的情况下发现长时间的高血糖和低血糖发作。两项非盲、实时研究检验了使用CGM指导干预预防住院糖尿病患者迫近低血糖/高血糖的可行性。

为了达到更严格的目标,研究者对日间皮下胰岛素治疗方案进行了调整,但48小时的传感器佩戴时间可能不够长,不足以看到日常变化带来的全部好处,一些医院医生并不总是接受这些建议。然而,如果发生低血糖,则需要更紧急的治疗。因此对该参数进行24小时监测和干预是有必要的。有趣的是,研究者发现胰岛素的每日平均剂量没有显著差异;然而,RT-CGM有可能通过对这些患者进行早期干预控制,从而改善TIR、平均血糖和高血糖。

虽然本研究是根据观察到的高血糖来选择参与者,但未来的研究应该考虑增加高血糖风险作为纳入标准。这项研究并没有直接从CGM读数中进行处理,虽然使用了趋势进行调整,但对这种方法进行评估是有价值的。
