High capillary glucose in the peri-operative period — exclude DKA, correct, or escalate to VRIII.
Draft — not yet clinically verified. Based on CPOC Diabetes Guideline (Oct 2023), §4 "Rescue treatment
for perioperative hyperglycaemia". Suspected DKA or HHS is a medical emergency — treat per local/JBDS
policy and call for senior help. Not a substitute for clinical judgement.
CBG (mmol/l)
Type 1 never has insulin fully stopped — basal insulin must always continue.
Ketones (mmol/l)
Check if unwell or CBG >13 (and daily if on an SGLT2 inhibitor — euglycaemic DKA). Leave blank if not yet measured.
Weight (kg)
Pre-filled at 70 kg (used for the 0.1 units/kg correction) — change to your patient.
