Effective management of Diabetic Ketoacidosis (DKA) is critical, yet medication errors can lead to severe complications. This study notes the importance of proper protocols and education to enhance patient safety in DKA treatment.
| 📌 Topic | 💡 Key Point |
|---|---|
| DKA Management | Insulin must be properly primed to avoid binding to PVC. |
| Resuscitation Protocol | D5W is contraindicated; use 0.9% Normal Saline. |
| Insulin Administration | Correct potassium levels before initiating insulin. |
| Patient Education | Provide sick-day rules and insulin transition strategies. |
⚠️ Medication Management
Insulin Binding to PVC
- Insulin is a peptide hormone that has a high affinity for PVC.
- Binding to the inner surface of IV bags can lead to ineffective doses.
- Consequence: Delayed stabilization of blood glucose and resolution of ketosis.
- Solution: Mandatory priming of IV tubing by flushing with insulin infusion.
🧪 Incident Analysis
Wrong Drug / Wrong Diluent
- Error Type: Dispensing D5W instead of 0.9% NS.
- Clinical Context: DKA volume expansion protocols were violated.
- Consequences: Exacerbation of hyperglycemia and failure of volume expansion.
- Corrective Actions: Implement ADA-aligned protocols and mandatory barcode scanning.
💉 Administration Protocols
Hypokalemia Risk
- Initiating IV insulin before correcting potassium can worsen hypokalemia.
- Key Thresholds: Hold insulin for K⁺ < 3.3 mEq/L.
- ADA Guidelines: Correct potassium before starting insulin infusion.
📚 Patient Counseling
Insulin Transition Strategies
- IV insulin should not be stopped before administering SubQ doses.
- Patient Education: Discuss sick-day rules and monitoring glucose and ketones.
- Timeline for Transition: Administer SubQ insulin 1-2 hours before stopping IV insulin to prevent coverage gaps.
