术中持续葡萄糖监测仪传感器-接收器连接性研究
该前瞻性先导研究纳入成年手术患者，将持续葡萄糖监测（CGM）传感器置于上臂外侧（三角肌）或大腿外侧，评估术中传感器-接收器连接性。结果显示无论电外科干扰如何，手术期间传感器-接收器连接性在 40 例（97.6%）中得以维持。研究提示替代传感器放置部位可支持术中 CGM 可行性。
要点
- 术中 CGM 传感器置于三角肌或大腿外侧时，连接性维持率可达 97.6%。
- 电外科干扰与传感器-接收器连接性无明显关联。
- 不同放置部位间接收器警报数量无显著差异。
核心结论
- 替代 CGM 传感器放置部位的传感器-接收器连接性一致，支持术中 CGM 应用的可行性。
研究设计与样本
- 前瞻性先导研究，纳入成年手术患者，CGM 传感器随机放置于三角肌或大腿外侧。
- 主要终点为手术期间 CGM 传感器-接收器连接性的持续时间比例。
主要发现
- 手术期间传感器-接收器连接性在 40 例（97.6%）中得以维持，无论是否受电外科干扰。
- 电外科干扰下大腿 21 例、三角肌 19 例维持连接，差异 0，95% CI 0–0，p=0.329。
- 26 次接收器警报中，11 次发生在电外科期间，15 次与电外科无关。
- 三角肌与大腿放置间接收器警报无差异，卡方 p=0.17，差异 0.18，95% CI −0.07 至 0.42。
临床怎么用
- 术中 CGM 传感器放置在三角肌或大腿外侧可减少体位相关传感器压迫。
- 电外科干扰下 CGM 传感器-接收器连接性仍可维持。
局限性
- 该研究为先导研究，未报告 CGM 传感器替代放置部位的准确性数据。

ABSTRACT Introduction Perioperative glycaemic control is associated with reduced postoperative complications. However, regulatory restrictions on point-of-care device operation and operative positioning constraints, reducing accessibility for dermal puncture, may hinder intraoperative monitoring. Although continuous glucose monitors (CGM) support real-time glucose monitoring, intraoperative patient positioning may increase compression low susceptibility, and electrosurgery interference may affect sensor-receiver connectivity. Alternative CGM sensor placement may improve intraoperative sensor-receiver connectivity. Methods In this prospective pilot study of adult surgical patients, CGM sensors were inserted in the lateral upper arm (deltoid) or lateral thigh (thigh) to limit patient position-related sensor pressure. The primary endpoint evaluated proportional duration of CGM sensor-receiver connectivity during surgery. Comparison of sensor-receiver connectivity by placement site, relation to electrosurgery and the number of alerts from the CGM receiver were also reported. Results Forty-five subjects were randomized: 22 deltoid and 23 thigh CGM placement. Four subjects were excluded; 20 deltoid and 21 thigh CGM sensor placements were analysed. Sensor-receiver connectivity was maintained during the surgical procedure in 40 (97.6%) irrespective of electrosurgery (21 thigh, 19 deltoid; difference 0, 95% CI: 0–0; p = 0.329). Of 26 receiver alerts, 11 occurred during electrosurgery; 15 were unrelated to electrosurgery. There was no difference in receiver alerts between deltoid and thigh placement (chi square p = 0.17; difference 0.18; 95% CI: −0.07 to 0.42). Conclusion Finding consistent sensor-receiver connectivity using alternative CGM sensor placement sites supports intraoperative CGM feasibility. If future studies demonstrate alternative CGM sensor placement sites retain accuracy, then broader intraoperative CGM application may be reasonable.
