A new study has revealed the presence of microplastics in medical intravenous (IV) infusion bags, raising concerns about potential health risks. Researchers estimate that thousands of plastic particles could be directly delivered into a patient’s bloodstream from a single bag of infusion fluid.
Published in the journal Environment & Health, the research, conducted by Liwu Zhang, Ventsislav Kolev Valev, and their team, examined commercially available 250-milliliter (8.4-ounce) saline solution bags, commonly used to deliver water, electrolytes, nutrients, or medication to patients.
The study found that both brands of saline solutions tested contained microplastic particles, primarily made from polypropylene, the same material used to manufacture the bags. This suggests that the bags themselves are shedding these tiny plastic fragments into the fluid. The researchers estimated that a single bag could release approximately 7,500 microplastics into the bloodstream.
“This figure rises significantly when multiple bags are used, such as during treatments for dehydration or abdominal surgery, potentially delivering tens of thousands of microplastic particles,” the study noted.
The microplastics discovered ranged in size from 1 to 62 micrometers. The researchers believe these particles, upon infusion, directly enter the recipient’s bloodstream, potentially leading to negative health effects.
While previous research from the 1970s indicated the presence of solid particles in IV fluid bags, this study is among the first to identify them as microplastics.
The researchers recommend several measures to mitigate microplastic shedding, including storing IV bags away from ultraviolet light and heat. They also suggest the implementation of micrometer-level filtration systems during infusions to remove the particles.
“While there are currently no clinical studies that have assessed the direct health risks of microplastic exposure from IV infusions, our findings underscore the need for further investigation,” the researchers stated. “This research will help provide a scientific basis for formulating appropriate policies and measures to mitigate the potential threats posed by microplastics to human health.”
The researchers hope their findings will prompt further studies into the long-term health effects of microplastic exposure through medical infusions.
