Gram Research analysis of a 2026 study found that IV nutrition given to premature infants can deliver chemicals to the body. Researchers detected 18 of 221 targeted chemicals, and their estimated BPA intake for a 1000 gram infant exceeded health guidance values. The findings suggest a need for further study rather than immediate changes to care.

Premature babies who cannot yet eat by mouth often receive parenteral nutrition, a liquid food delivered directly into a vein. A new single-center study, reviewed by Gram Research analysis, tested a standard IV nutrition recipe for a 28-week, 1000 gram infant by running it through the same tubing used in hospitals. Researchers detected 18 of 221 chemicals they checked for. The most common were diisononyl phthalate, a plasticizer, and bisphenol A (BPA), a chemical used in some plastics. Based on the amounts found, estimated BPA intake appeared to exceed health guidance values. The researchers also noted that premature infants may clear these chemicals more slowly because their livers are still developing. The study did not measure harm to babies, and an early look at blood samples suggested IV nutrition is one contributing source of exposure rather than the main one. The findings point to a clinical scenario worth further study, not a full picture of exposure across all premature infants.

Key Statistics

A 2026 single-center study published in Environmental Science & Technology found that 18 of 221 targeted chemicals were detected in a standard IV nutrition recipe for a 28-week, 1000 gram premature infant.

The same 2026 study estimated that bisphenol A intake from the IV nutrition regimen reached 9.5 micrograms per kilogram of body weight per day, which the researchers reported as exceeding health-based guidance values.

In the 2026 study, diisononyl phthalate had the highest average concentration in the IV nutrition fluid at 780 nanograms per milliliter, followed by bisphenol A at 250 nanograms per milliliter.

The Quick Take

  • What they studied: Researchers asked whether chemicals from plastic tubing, packaging, and other sources end up in the IV nutrition that premature babies receive, and how much a baby might take in.
  • Who participated: The team did not enroll babies for this part of the work. They tested one standard IV nutrition recipe designed for a reference infant born at 28 weeks and weighing 1000 grams. A small exploratory look at blood samples from extremely premature infants was also included. The exact number of babies in that blood analysis was not clearly reported.
  • Key finding: Of 221 chemicals checked, 18 were detected in the nutrition fluid after it passed through the tubing. Diisononyl phthalate averaged 780 nanograms per milliliter and BPA averaged 250 nanograms per milliliter, the highest levels found. The estimated daily BPA intake was 9.5 micrograms per kilogram of body weight, which the researchers said was higher than health guidance values.
  • What it means for you: This research suggests that the IV nutrition used in newborn intensive care may expose premature babies to chemicals that their developing bodies clear slowly. Parents and clinicians may want to ask care teams how they reduce chemical exposure. Families should not change any medical care based on this study alone.

The Research Details

This was a single-center case study, meaning it looked closely at one hospital setting rather than following many patients over time. The researchers prepared a standard IV nutrition recipe for a 28-week, 1000 gram baby, which is a typical model used in neonatal care. They ran this liquid through the same kind of infusion tubing used at bedsides and collected the fluid that came out the other end.

The fluid was then tested with a highly sensitive laboratory method called LC-MS/MS. This method can search for hundreds of chemicals at once and identify them by their weight and structure. The team checked for 221 target chemicals, many of which are found in plastics, food packaging, and personal care products.

Because the test measured the fluid rather than the babies themselves, the researchers also used computer models to estimate how much a baby might absorb and how the body might break those chemicals down. These models are useful for planning but depend on assumptions about how babies process chemicals.

Measuring the fluid directly shows what could reach a baby before any absorption happens. This is an important first step because it identifies sources of exposure that hospitals might be able to change. Adding computer models helps estimate what a baby’s body might do with those chemicals, which is useful when studying groups that cannot easily be tested, like very early newborns.

The study used a sophisticated, broad chemical screening method, which is a strength. It was published in Environmental Science & Technology, a well-respected journal in environmental research. However, it looked at one recipe in one hospital setting, so the results may not match other hospitals or other IV formulas. The researchers also clearly stated that their findings represent a clinical example rather than an estimate for all premature infants. The exact number of babies in the blood analysis was not clearly described, which limits how much weight that part can carry.

What the Results Show

The team found 18 of the 221 chemicals they searched for in the IV nutrition fluid. Diisononyl phthalate, a softening agent used in some plastics, had the highest average concentration at 780 nanograms per milliliter. BPA, a chemical used to make certain plastics and resins, followed at 250 nanograms per milliliter. Methylparaben, a preservative used in some products, and a breakdown product of certain sugars called 5-hydroxymethyl-2-furanoic acid were also present at measurable levels.

The researchers estimated how much BPA a 1000 gram baby might take in each day. Their estimate was 9.5 micrograms per kilogram of body weight, which they reported as higher than both their own calculated safety value and official health guidance values. This is a model-based estimate from the fluid tests, not a measurement of what babies actually absorbed.

The computer models also suggested that premature babies may build up certain chemicals in their bodies. This is because their livers are still developing and may not break down substances as efficiently as an adult’s liver. The models also raised a question about a related BPA breakdown product, which the authors said deserves further study.

Finally, an exploratory look at blood samples from extremely premature infants suggested that IV nutrition is a contributing source of chemical exposure, but probably not the main one. Other sources, such as medical devices, medications, and hospital environments, may also play a role.

The study highlights that the chemicals found may not all come from one place. Because many of them are common in plastics and personal care products, the total exposure a baby receives likely comes from several sources. This is important for hospital teams because it suggests that changing one product may help, but may not solve the whole problem. The pharmacokinetic models also showed how immature detoxification can change the picture, meaning that the same amount of a chemical may be more concerning for a premature baby than for an older child or adult.

Concern about chemicals in neonatal care is growing. Earlier research has shown that plastic-containing medical tubing and bags can release phthalates and other chemicals into IV fluids. Public health agencies have also set guidance values for chemicals like BPA, and this study compares its estimates against those values. The current work adds a more complete chemical screen and pairs it with models designed for premature infants. Because it focuses on one recipe in one center, it fits as an early signal that supports the need for larger studies rather than replacing them.

The study looked at one IV nutrition recipe in one hospital setting, so the results may not reflect other formulas, tubing types, or hospitals. The chemical amounts were measured in fluid, not in babies, and the estimates of daily intake and body buildup rely on computer models with assumptions that may not match real infants. The blood sample analysis was exploratory and the number of participants was not clearly stated. Finally, the study did not measure health effects in babies, so it cannot tell us whether these chemical levels cause harm.

The Bottom Line

Research suggests that hospitals and care teams should consider reviewing the plastic components and additives in IV nutrition systems used for premature babies. Confidence in this recommendation is moderate, because it is based on a single-center study showing chemicals in fluid, not on proof of harm. Parents and clinicians should not stop or change any prescribed IV nutrition based on this study. Decisions about care should be made with the baby’s medical team, who can weigh the risks and benefits of nutrition support.

Neonatal clinicians, pharmacists, hospital purchasing teams, and families of premature infants may find this research useful for asking informed questions. Researchers studying chemical safety in early life will also find it relevant. Adults and families who are not caring for a premature baby can apply the general lesson about reducing everyday exposure to plastic-related chemicals, but this study does not provide specific guidance for them.

Changes in hospital product design or purchasing typically take months to years because they require testing, approval, and supply changes. Larger studies that measure chemical levels in babies and track health outcomes will likely take several years to complete. Families should expect a gradual process of research and policy review rather than immediate changes to standard care.
