how to prescribe sliding scale insulin
continue long acting insulin at normal dose + time. (lantus, glargine, levemir, isophane, humulin 1)
50units actrapid to 49.5l of 0.9%sodium chloride -> 1unit/ml . syringe pump.
insulin requirements are 0.5-1unit per kg.
sign the scale required.
check glucose every hour if unstable. 2-4h if stable control.
fluids prescribe
dex-saline(0.18% NaCl + glucose 4%) + KCL (70mmoll/24h)
recheck U+Es
resign vrii chart daily
Stopping: confirm eating and drinking
ensure long acting on board 1h before stopping.
give mixed/rapid insulin at usual mealtime. and wait 30mins before stopping VRII.
monitor CBG QDS for 24h.
