How is blood glucose checked on the step-down unit: by finger stick method or arterial line sampling?
A. We use the finger stick method; the arterial lines come out in the unit, prior to transfer. Some patients have central lines still in that are capped; glucoses can be drawn from here as well. 5. Do you advocate maintaining the A-line to facilitate frequent blood sugar testing? I am concerned about potential patient discomfort and sleep deprivation with hourly finger sticks. What about non-invasive methods of measuring BG? A. We recommend the A-line only in the ICU. We use finger sticks if there is no central IV line present. By the time patients have their lines out following surgery, their BG levels and insulin infusions should be at a stable rate and every 2 – 4 hourly BG checks are all that will be required per protocol at that point. We just do finger sticks at this point, but are investigating the feasibility of non-invasive monitors.
