INS and Hypoglycemia: The results showed that using 5 units of IV insulin reduced the risk of posttreatment hypoglycemia compared to 10 units of IV insulin (OR 0.307, 95% CI 0.117 to 0.806), which preserved potassium lowering effects (potassium difference -0.096 mmol/L, 95%CI -0.250 to 0.058, p 0.221) [26].
