The increasing survival rates of nanopreterm infants—those born weighing less than 750 grams or before 25 weeks of gestation—present new challenges in neonatal care, particularly in providing adequate parenteral nutrition (PN). These extremely fragile infants have underdeveloped metabolic systems, making precise nutrient delivery critical. However, existing PN guidelines for extremely low-birth-weight (ELBW) infants may not fully address their unique needs, creating a demand for specialized solutions.
Nanopreterm infants require carefully balanced PN support due to their limited glycogen stores, immature glucose metabolism, and heightened sensitivity to nutrient imbalances. Immediate but controlled dextrose administration is essential to prevent hyperglycemia, while lipid intake must be carefully monitored to avoid metabolic overload. Additionally, protein delivery must be optimized to support growth without overwhelming their underdeveloped systems.
EVA-based PN bags offer a reliable solution for meeting these challenges. The ethylene-vinyl acetate (EVA) material ensures compatibility with sensitive PN components, maintaining stability for lipids, amino acids, and micronutrients. Unlike traditional materials, EVA minimizes leaching and contamination risks, which is crucial for immunocompromised neonates. The flexibility and durability of EVA bags also make them ideal for prolonged PN administration in neonatal intensive care units (NICUs), where sterility and precision are paramount.
Lingze Medical's TPN bags are manufactured using premium EVA material and are available in various sizes and specifications to meet diverse clinical needs. For enhanced safety, optional protective shielding bags can be provided upon customer request to prevent leaching. Our products meet the highest international standards, holding CFDA, FDA, and CE certifications. We have successfully partnered with healthcare institutions across multiple countries, delivering reliable parenteral nutrition solutions.
