有人提出,实现闭环人工胰腺的第一步可能是使用连续葡萄糖传感器,根据预计的低传感器葡萄糖值自动暂停基础胰岛素输送。我们回顾了最近在 17 名患有 1 型糖尿病 (T1D) 的青少年中使用人工胰腺系统的经验,利用比例积分微分 (PID) 算法来评估该操作的安全性和有效性。在 34 小时闭环自动胰岛素输送期间,8 名受试者发生 18 次泵暂停≥60 分钟(90 ± 18 分钟)。传感器葡萄糖水平从 159 ± 42 mg/dL 降至最低点 72 ± 13 mg/dL。相应的血浆葡萄糖水平从 168 ± 51 降至 72 ± 16 mg/dL,18 个事件中仅 4 个事件记录到值 <60 mg/dL。这些数据表明,使用 PID 算法的自动泵暂停可能是预防青少年 T1D 低血糖的有效手段。
It has been proposed that the first step towards a closed-loop artificial pancreas might be to use a continuous glucose sensor to automatically suspend the basal insulin delivery based on projected low sensor glucose values. We reviewed our recent experience with an artificial pancreas system, utilizing a proportional-integrative-derivative (PID) algorithm, in 17 adolescents with type 1 diabetes (T1D) to assess the safety and efficacy of this maneuver. During 34 h of closed-loop automated insulin delivery, 18 pump suspensions ≥60 min (90 ± 18 min) occurred in eight subjects. Sensor glucose levels fell from 159 ± 42 mg/dL to a nadir of 72 ± 13 mg/dL. Corresponding plasma glucose levels fell from 168 ± 51 to 72 ± 16 mg/dL, with values <60 mg/dL recorded in only four of the 18 events. These data suggest that automatic pump suspension using the PID algorithm may be an effective means to prevent hypoglycemia in youth with T1D.
