Intravenous nutrition infusion bag instead of traditional single bottle infusion, it simplifies the operation of nutrition infusion, closed infusion does not need to exhaust, reduces the chance of nutrient solution pollution, at the same time, 24-hour continuous infusion reduces the workload of nurses, which is recognized by the majority of nurses. But is there any other material migration and release in the infusion bag during the use? Does it react with or adsorb drugs? Does it have adverse effects on the quality of total parenteral nutrition (TPN) and patients? These are the problems that clinical medical workers are very concerned about.
1、 Problems of PVC and EVA commonly used at present
At present, the commonly used materials of disposable intravenous nutrition infusion bag are PVC and its copolymer and EVA.
1. Main problems of PVC
(1) Polyvinyl chloride (PVC) contains PVC monomer, which is harmful to human health.
(2) In order to change the properties of polyvinyl chloride (PVC), diethylhexyl phthalate (DEHP) plasticizer is often added in the production process of PVC. During the use of DEHP, the plasticizer may dissolve out. Diethylhexyl phthalate (DEHP) is a harmful substance and can release estrogen. Therefore, it may contact with diethylhexyl phthalate (DEHP) It leads to reproductive system dysplasia and seriously endangers human health.
(3) In order to prevent the degradation of PVC resin, stabilizers containing calcium, zinc, barium and other elements are usually added in the production process of polyvinyl chloride (PVC). These metal ions may migrate in the process of infusion, and enter the human body with the medicine liquid or blood products, which has an impact on human health.
(4) Polyvinyl chloride (PVC) has strong adsorption to some fat soluble and alcohol soluble drugs, especially antitumor drugs, which leads to inaccurate prescription dosage and reduced efficacy.
(5) After burning PVC and its copolymer, hydrochloric acid will be formed, which will cause respiratory tract injury of human and animals and erosion of buildings. In addition, dioxin is easy to be produced during combustion, which has a profound impact on the environment.
