Efficacy of continuous intravenous glucose monitoring in perioperative glycaemic control: a randomized controlled study

<span class="paragraphSection">Editor—Effective treatment of perioperative hyperglycaemia has proved difficult.<a href="#aew455-B1" class="reflinks">¹</a> Continuous glucose monitoring (CGM) might improve perioperative treatment without increasing the risk of hypoglycaemia.<a href="#aew455-B2" class="reflinks">²</a> The reported accuracy of current CGM via central and peripheral venous sampling is 5.6–7.5%.<a href="#aew455-B3" class="reflinks">³</a><a href="#aew455-B4" class="reflinks">⁴</a> In this pilot study, we investigated the efficacy of perioperative CGM via peripheral i.v. sampling in patients with diabetes mellitus (DM) type 2 compared with standard care. We hypothesized that the availability of CGM data during surgery would lower postoperative glucose values.</span>
