Continuous glucose monitoring following pancreatectomy with islet autotransplantation in children.

Abstract

Aim was to determine whether CGM could accurately monitor blood glucose concentration in the immediate postoperative period following pancreatectomy with IAT in children. CGM was used in nine patients undergoing IAT at our institution between April 2015 and September 2016 (eight total pancreatectomy and one subtotal pancreatectomy). MAD and MARD of CGM values compared to time-matched serum blood glucose were calculated during the first 5days of ICU admission. Goal range was defined as 70-140mg/dL and out-of-range was >140mg/dL or <70mg/dL. Of 89 time-matched measures found, 75% of CGM values were within 15mg/dL, and 51% were within 10mg/dL, compared to serum glucose. MAD was 11.6mg/dL, and MARD was 10.6%. CGM values did not differ from serum glucose (P=.74). By Clarke error grid analysis, 100% of paired values were in clinically acceptable zones. By surveillance error grid analysis, 96% of paired values were within clinically acceptable agreement. CGM is a reliable tool in monitoring glycemic control in the immediate postoperative period following pancreatectomy with IAT in children.
