Interactive Guide for the Management of Pediatric Diabetic Ketoacidosis (DKA)
This is a clinical support tool designed to facilitate the management of DKA in pediatric patients, based on the most recent consensus guidelines. Use the navigation to quickly access protocols, calculators and treatment guides. pediapp.online© 2026
Application Purpose
This application translates CAD clinical guidance into interactive tools to streamline decision making. It does not replace clinical judgment. Always consult the full guidelines and consider each patient's individual context.
Diagnosis and Severity Classification
The diagnosis of CAD is based on a biochemical triad. The severity is classified according to the degree of acidosis. Use the interactive chart for quick orientation.
Hyperglycemia
> 200 mg/dL
(> 11.1 mmol/L)
Metabolic acidosis
pH < 7.3
Bicarbonate < 18 mEq/L
Ketonemia
BHB ≥ 3 mmol/L
or moderate/large ketonuria
DKA Severity Classification
Initial Evaluation and Stabilization
The initial evaluation should be systematic (ABC), prioritizing hemodynamic stabilization and neurological evaluation.
Immediate Critical Steps
- Airway, Breathing, Circulation (ABC): Ensure permeability and evaluate circulatory status.
- Neurological Evaluation (D): Use Glasgow scale. An altered mental state is a red flag for cerebral edema.
- Hydration Status: Assume a 5-10% deficit. Clinical signs can be misleading due to hyperosmolarity.
- Access IV and Laboratories: Get 2 IV accesses if possible. Submit STAT labs: Glucose, electrolytes, venous gases, BHB, kidney function, blood count.
- Corrected Sodium: Fundamental to guide fluid therapy. A rapid decline is a warning sign. The formula is: Measured Na + [1.6 * (Glucose - 100) / 100].
Clinical Note: Leukocytosis is common due to stress and does not always indicate infection. Kussmaul's breathing can cause mucosal dryness regardless of volume status.
Fluid Therapy Calculator
Rehydration is the cornerstone of treatment. Use this calculator to estimate fluid requirements. Fluid therapy should be started BEFORE insulin.
Patient Parameters
Insulin Therapy Guide
Insulin is key to reversing ketosis. The infusion should be continuous and begin 1-2 hours after starting the fluids.
Never administer an IV bolus of insulin!
May increase the risk of brain edema.
Infusion Dose Calculation
Key Points
- Start: 1-2 hours after initial fluid therapy.
- Potassium Requirement: Start only if serum K+ is ≥ 3.5 mmol/L.
- Standard Dose: 0.05 to 0.1 units/kg/hour.
- Glucose Target: Maintain between 150-250 mg/dL.
- Adjustment: If glucose drops too quickly, increase dextrose in fluids, DO NOT decrease insulin (unless strictly necessary).
Electrolyte Management
Potassium management is critical due to total body deficit, despite normal or high initial serum levels. Baking soda is almost never indicated.
Potassium (K+) Replacement Protocol
Select the patient's serum potassium level to see the recommended action.
< 3.0 mmol/L
Severe hypokalemia
3.0 - 5.5 mmol/L
Normal/Expected Range
> 5.5 mmol/L
Hyperkalemia
About Bicarbonate and Phosphate
Baking soda: NOT routinely recommended. It is associated with a higher risk of cerebral edema. Reserve only for life-threatening hyperkalemia or severe acidosis (pH < 6.9) with cardiac involvement.
Phosphate: Replacement is not routine. Consider only if there is severe hypophosphatemia (< 0.5 mmol/L) with cardiac or respiratory dysfunction.
🧠 ALERT: Cerebral Edema
It is the most serious and potentially fatal complication of DKA. Clinical suspicion requires immediate treatment, WITHOUT WAITING for confirmation by imaging.
Risk Factors
- Age < 5 years
- New onset diabetes
- High initial BUN and severe hypocapnia
- Administration of bicarbonate or insulin bolus
- Rapid fall in osmolality or failure to increase corrected Na+
Warning Signs and Symptoms
- Headache (new or worsening)
- Recurrent vomiting
- Change in state of consciousness (irritability, lethargy)
- Inappropriate bradycardia or high blood pressure
- Oxygen desaturation or respiratory depression
Emergency Management
1. Restrict IV Fluids
Reduce the infusion rate.
2. Hyperosmolar Therapy
Mannitol: 0.5-1 g/kg IV in 20 min OR Hypertonic Saline (3%): 2.5-5 mL/kg in 10-30 min.
3. Position and Support
Elevate head to 30°. Notify the pediatric ICU immediately.
Transition to Subcutaneous Insulin and Discharge Education
The transition to subcutaneous (SC) insulin is performed once ketoacidosis has resolved and with the patient tolerating the oral route.
CAD Resolution Criteria
- Venous pH > 7.3
- Serum bicarbonate ≥ 15 mmol/L
- β-hydroxybutyrate (BHB) < 1.0 mmol/L
- Patient clinically well, tolerating oral intake.
Transition Plan
- Administer the first dose of SC insulin (basal and/or rapid).
- Wait 1-2 hours before stopping the IV insulin infusion to allow the SC insulin to begin working.
- Calculate the total daily dose of SC insulin (TDD) based on weight (e.g. 0.5-1 U/kg/day for debut).
Discharge Education: Fundamental Pillars
Structured education is key to preventing recurrences. Make sure the family understands:
- Insulin management on "sick days" (Sick Day Rules).
- Glucose and, crucially, ketone monitoring.
- Recognition of the warning signs of CAD.
- When and how to contact the health team.
