Several experimental studies have observed relationships between hypokalemia and prolonged corrected QT QTc interval, which causes fatal cardiac arrhythmias and sudden death [ 6 - 8 ]. It has been well described that a decrease in serum potassium during insulin induced hypoglycemia is caused both by insulin and adrenaline [ 910 ].

Furthermore, a relationship between insulin induced hypoglycemia and hypokalemia during hypoglycemia in diabetes has been reported.

Recently, one study reported alterations of all electrolytes during insulin induced hypoglycemia in patients with type 1 diabetes. This study suggested hypoglycemia causes increases in serum sodium and chloride levels and decreases in serum potassium levels [ 11 ]. However, one study reported altered serum sodium and chloride levels during severe hypoglycemia in diabetes rare, whereas alterations of all electrolyte levels during severe hyperglycemia, such as diabetic ketoacidosis and a hyperglycemic hyperosmolar state, have been well established [ 12 ].

Incidences of hypokalemia during severe hypoglycemia in patients with type 2 diabetes appear to be lacking in the documents.

Serum electrolyte, creatinine, blood urea nitrogen BUN and glucose levels were recorded prior to the administration of carbohydrates by the Emergency Department. The vital signs were monitored hourly for all patients and were checked more frequently for patients whose vital signs remained unstable.

We also assessed hemoglobin A1c HbA1cplasma C-peptide levels, blood glucose levels, plasma insulin levels, and serum chemistry profiles obtained during severe hypoglycemia before carohydrates were administered. Levels below the normal range are defined as hypo- and levels above the normal range are defined as hyper. These individuals were not treated with antihypertensive or vasopressor drugs during this period. Continuous variables were compared using a Mann-Whitney U test or paired t test.

Categorical variables were compared using chi-square tests. Correlations were evaluated using Pearson correlation coefficient or Spearman rank correlation coefficient.

Adults with diabetic ketoacidosis typically need a minimum of 3 L of saline over the first 5 h. When blood pressure is stable and urine flow adequate, normal saline is replaced by 0. Pediatric maintenance fluids for ongoing losses must also be provided. Initial fluid therapy should be 0.

Maintenance Fluid Calculation for Children Correction of hyperglycemia and acidosis Hyperglycemia is corrected by giving regular insulin 0. Insulin adsorption onto IV tubing can lead to inconsistent effects, which can be minimized by preflushing the IV tubing with insulin solution. Children should be given a continuous IV insulin infusion of 0.

Ketones should begin to clear within hours if insulin is given in sufficient doses. Serum pH and bicarbonate levels should also quickly improve, but restoration of a normal serum bicarbonate level may take 24 h. If used, only modest pH elevation should be attempted target pH of about 7.

Insulin dosage can then be reduced to 0. Insulin replacement may then be switched to regular insulin 5 to 10 units sc q 4 to 6 h. When the patient is stable and able to eat, a typical split-mixed or basal-bolus insulin regimen is begun.
