Accuracy of intermittently scanned continuous glucose monitoring during caesarean delivery in pregnant women with insulin-treated diabetes
Authors' conclusion
The accuracy of isCGM during caesarean delivery was good, particularly for glucose values between 70 and 110 mg/dL, when CG confirmation could be safely avoided.
Study context
- Population
- Pregnant women with insulin-treated diabetes during caesarean delivery68 paired isCGM-CG data
- Participants

- Comparison
- Intermittently scanned CGM (isCGM) vs simultaneously measured capillary glucose
- Outcome
- Intrapartum accuracy of isCGM vs CG (MARD and Clarke Error Grid analysis)
- Follow-up
- During caesarean delivery
Methodological detailspaired measurements
- Paired measurements

- Impact on intrapartum management: isCGM-CG pairs in the same glycemic range (same management) — All discordant data identified by checking capillary glucose (CG) when isCGM >110 mg/dL or <70 mg/dL (chi-square 21.76)
- p < 0.001
