Maintain atient ithin urrent lgorithm-nce BG is in Goal ange djust T within current algorithm until patient is in goal range for 4 hours nce patient is within goal range for 4 hours, there is no need to adjust T unless BG falls out of goal range atient Monitoring: heck BG every hour until it is within goal range for 4 hours. Then check every 2 hours X2, then every 4 hours. esume hourly checks if BG falls out of goal range. ourly monitoring may be indicated for critically ill patients even if they have stable blood glucose. f patient is eating, check BG every hour X 3 after meals. T/Tube Feeds o ecrease insulin infusion rate by 50% if nutritional therapy is discontinued or significantly reduced and check BG every hour X 4 hrs. Treatment of ypoglycemia (BG<60 mg/d) igns and symptoms include, palpitations, diaphoresis, weakness, altered mental status. Turn off drip Give 50 V o BG mg/d 25 m (1/2 amp) o BG <50 mg/d 50m (1 amp) echeck BG every 20 minutes and repeat 25m of 50 V if BG<60mg/d. estart drip once blood glucose is >70 mg/d X2 checks. estart infusion at a lower algorithm (see moving down). otify the hysician: For any blood glucose change >100 mg/d in one hour. For blood glucose > 360 mg/d For any hypoglycemia which results in loss of consciousness For hypoglycemia which has not resolved within 20 min of administering 50m of 50 V and discontinuing the insulin infusion.
