ABSTRACT
Objective:
The primary objective was to assess the difference in rates of hypoglycemia (blood glucose (BG) <=70 mG/dL) when using reduced-dose (5 units) vs. standard-dose (10 units) of IV regular insulin for hyperkalemia treatment in renal insufficiency. Secondary objectives include the efficacy of insulin dose on potassium reduction and evaluating the difference in rates of severe hypoglycemia (BG <=54 mG/dL) between the groups. Method(s) This was a retrospective chart review of patients with renal insufficiency treated with IV regular insulin for hyperkalemia at a tertiary care teaching hospital from June 2020 to June 2021, with institutional review board approval. Inclusion criteria encompassed patients aged 18 years and older with elevated baseline potassium (>=5.5 mEq/L), estimated glomerular filtration rate < 30 mL/min/1.73m2, end stage renal disease, or presence of acute kidney injury, having received either 5 or 10 units of IV regular insulin for hyperkalemia, and had documented glucose and potassium levels after insulin administration. Patients who were pregnant, had diabetic ketoacidosis, or a baseline BG <=70 mG/dL were excluded. Data collection included patient demographics, diabetes history, relevant labs at time of elevated potassium, doses of insulin and dextrose administered for hyperkalemia treatment, presence of coronavirus-19 infection, glucose levels within 6 hours and first potassium level within 24 hours following insulin administration, concurrent use of potassium-lowering agents, insulin outside of hyperkalemia treatment, or steroids, and mortality. Result(s) Out of 409 patients included, 92 were in the 10-unit group and 317 in the 5-unit group. The rate of hypoglycemia in the 5-unit arm vs. the 10-unit arm was 6.9% vs. 8.7% (p=0.649), respectively. The rate of severe hypoglycemia between the 5-unit arm and the 10-unit arm was 3.2% vs 5.4% (p=0.682), respectively. The percent normalization of potassium was not statistically different between the 5-unit group and the 10-unit group (59% vs. 68%;p=0.115), with the same mean reduction in potassium from baseline (0.8 mEq/L (p=0.947)). Administration of concurrent treatments for hyperkalemia was similar between the groups, with dialysis being the only one with statistical significance in normalization of potassium. Patient characteristics that could have an impact on risk of hypoglycemia were studied and analyzed, including pre-treatment BG, history of diabetes mellitus, insulin naive, and patient weight. In patients with hypoglycemia (n=30) vs. those without hypoglycemia (n=379), there was a significantly different mean pre-treatment BG (113 mG/dL vs. 178 mG/dL, p<0.001). Discussion/Conclusion:
There was no significant difference in rates of hypoglycemia and severe hypoglycemia between the 5-unit vs. 10-unit groups. There was no significant change in potassium normalization between the two insulin doses. Because of the small number of hypoglycemia events, larger studies are needed to better understand if 5 units of regular insulin is a safer option for the treatment of hyperkalemia in renal insufficiency.Copyright © 2023
