Dynamic Image Analysis To Evaluate Subvisible Particles During Continuous Drug Infusion In a Neonatal Intensive Care...

Area of Science:

• Neonatal medicine
• Pediatric critical care
• Pharmaceutical science

Background:

• Particulate matter in intravenous (IV) infusions can cause serious complications in critically ill children, including inflammation and organ dysfunction.
• Limited data exists on the quantity of particulate matter administered to patients, especially infants, during multidrug IV therapies.

Purpose of the Study:

• To quantify particulate matter administered to preterm infants during common multidrug IV therapies in a neonatal intensive care unit (NICU).
• To determine the size distribution of infused particles and identify potential risks for fragile infants.

Main Methods:

• Two standard neonatal intensive care unit (NICU) multidrug IV therapy protocols were replicated in a laboratory setting.
• A dynamic particle analyzer was used to measure particulate matter contamination over 24 hours, assessing both quantity and size.
• Infusion flow rates were kept low to simulate clinical conditions for preterm infants.

Main Results:

• Significant particulate contamination was detected, with up to 85,000 particles infused per day, particularly during discontinuous infusions.
• Very large particles, approximately 60 µm in size, were found in the infused fluids.
• No visible particles were observed during the drug infusions, highlighting the need for analytical measurement.

Conclusions:

• Infants, even with low IV infusion rates, can receive a substantial number of potentially harmful particles, especially in NICU settings.
• Particulate contamination in IV fluids poses a significant risk to vulnerable preterm infants.
• Implementing preventive strategies, such as the use of in-line filters, is crucial to mitigate particulate contamination risks.
