What is the recommended method for administering heparin via IV infusion?

Infusing heparin using an electronic IV pump is the recommended method because it allows for precise control over the infusion rate and dosages, which is crucial for managing anticoagulation therapy. Heparin has a narrow therapeutic index, meaning the range between a therapeutic dose and a potentially harmful dose is quite small. An electronic IV pump can accurately deliver heparin at the prescribed rate, ensuring that the patient receives a consistent and reliable dosage over time.

Additionally, IV pumps often have built-in safety features, such as infusion alarms and programmable limits, which enhance patient safety by reducing the risk of overdosing or underdosing. Manual infusion or using gravity methods can lead to variations in flow rates due to changes in patient positioning, line obstructions, or other factors, increasing the risk of complications.

Mixing heparin with normal saline for infusion is typically not done unless specifically directed, as it can alter the pharmacokinetics of the drug and potentially lead to inaccuracies in dosing. Thus, the use of an electronic IV pump stands out as the most effective and safest method for administering heparin intravenously.
