An Ex Vivo Study Examining Migration of Microplastics from an Infused Neonatal Parenteral Nutrition Circuit
AI summary Read the abstract
This ex vivo study quantified microplastics released from neonatal parenteral nutrition infusion circuits, finding that plastic particles migrate from the tubing and connectors into infused solutions, raising concerns about iatrogenic microplastic exposure in vulnerable neonatal patients.
Figure 1. Overview of microplastic concentration (A), polymer composition (B), and size distribution (C) in the crystalloid solution collected in a simulated parenteral nutrition circuit and administered over a course of maximum 72 h with samples at time 0 (T0), T12, T24, T48, T72. The T0 measurements represent information on microplastics in the original fluid, without transition through the circuits. The number of samples per time point is indicated in panel A with "N=." Two particles (size 976 and 1,274:9 lm) are not included in the figure of the size distribution (Figure Plastic polymer types (Figure Corresponding numeric data of the figure can be found in Supplementary data at https://zenodo.org/records/10102884 ("Supporting data -Numeric data.docx").

Microplastics in neonates: an overlooked cost of parenteral nutrition
AI summary Read the abstract
Researchers detected microplastics in neonatal blood at levels that increased with parenteral nutrition duration, with larger particles over 60 µm found exclusively in long-term recipients — suggesting that intravenous nutrition delivery systems may be an underrecognized iatrogenic source of microplastic exposure in vulnerable newborns.

The Hidden Plastic Pathway: Microplastic Migration from Enteral and Parenteral Nutrition Systems in Intensive Care
AI summary Read the abstract
This review paper looks at feeding tubes and IV nutrition equipment used for seriously ill hospital patients, such as containers, tubing and connectors made of plastic. It summarizes existing research on how tiny plastic particles or chemicals might move from this equipment into the nutrition fluids patients receive, and outlines areas needing further study.
Factors affecting micro(nano)plastic release during intravenous therapy: Direct blood exposure.
AI summary Read the abstract
This study systematically evaluated factors affecting micro(nano)plastic (MNP) release from medical infusion products during intravenous therapy. Results indicated that MNPs are released into IV fluid at measurable levels, potentially delivering plastic particles directly into the bloodstream of patients.
