[Problems with infusion of vasoactive drugs]

Area of Science:

• Critical Care Medicine
• Biomedical Engineering
• Pharmacology

Background:

• Patient safety during critical care is paramount.
• Infusion systems, particularly syringe pumps, are vital for delivering vasoactive drugs.
• Technical failures in infusion systems can lead to adverse patient events.

Observation:

• An obstruction in an infusion system caused unintended norepinephrine boli delivery in a patient with septic shock.
• Sudden hemodynamic disturbances in critically ill patients necessitate evaluation of both pathological and technical causes.
• Inadequate alarm systems on syringe pumps can result in critical medication errors.

Findings:

• A lack of adequate alarm devices on syringe pumps can severely compromise patient safety.
• A case study revealed that infusion system obstruction led to dangerous intermittent dosing of norepinephrine.
• Sensitive alarming systems are crucial for preventing inappropriate drug delivery via syringe pumps.

Implications:

• Enhanced alarm systems for syringe pumps are essential for improving patient safety in critical care settings.
• Recommendations for safe vasoactive drug infusion include using singular, pressure-controlled devices with specific infusion parameters.
• Proactive identification and mitigation of technical failures in infusion systems are critical for preventing patient harm.
