Comparative study on the migration of di-2-ethylhexyl
In this study the migration behavior of three different blood tubing sets (PVC material with two different plasticizers and silicone as control material) applied on a heart-lung machine standardly used for cardiopulmonary bypass (CPB) in children was studied.

Comparative study on the migration of di-2-ethylhexyl
These plasticizers may migrate into the blood leading to an exposure of the patients. In this study the migration behavior of three different blood tubing sets (PVC material with two different plasticizers and silicone as control material) applied on a heart-lung machine standardly used for cardiopulmonary bypass (CPB) in children was studied.

Leaching of plasticizers from polyvinylchloride perfusion
Plasticizer leaching from different PVC perfusion lines into different lipid emulsions. 3.3. Influence of tube diameter The leaching rate of DEHP and DEHT was decreased by 33% in both groups by using tubes with an internal diameter of 3 mm instead of 1.5 mm, the data are shown in Table 4.
- Do plasticizers migrate into the blood?
- These plasticizers may migrate into the blood leading to an exposure of the patients. In this study the migration behavior of three different blood tubing sets (PVC material with two different plasticizers and silicone as control material) applied on a heart-lung machine standardly used for cardiopulmonary bypass (CPB) in children was studied.
- Is DEHP substitute TOTM an effective alternative plasticizer for PVC medical devices?
- In conclusion, the DEHP substitute TOTM promises to be an effective alternative plasticizer for PVC medical devices particularly regarding the decreased migration rate during medical procedures. 1. Introduction Medical devices often consist of PVC (polyvinyl chloride) material that requires the use of plasticizers.
- Why are PVC medical devices so popular?
- Since then, PVC medical devices have become ubiquitous thanks to their light weight, softness, low manufacturing cost, transparency, recyclability, water and chemical resistance and resilience , . However, to make PVC soft and flexible, PVC must be mixed with plasticizers.
- What is the energy gain of plasticizer leaching?
- If we assume that half of the solvation layer is recovered during the migration into bulk solution, the plasticizer leaching allows an energetic gain between -44 and -33 kJ mol −1 in water and between -59 and -49 kJ mol −1 in ethanol. In the water-ethanol mixture, the gain ranges from -64 to -47 kJ mol −1. Fig. 6.
- Does a plasticizer interact with a non-Plasticized PVC surface?
- The free energy profiles calculated in vacuum in Fig. 5 a show that the net interaction between the plasticizer and the non-plasticized PVC surface is very favorable with well-depths of around -129 ±2 kJ mol −1 between the different plasticizers.
- Do plasticizers migrate from PVC surfaces?
- Long duration simulations showed plasticizer migration from PVC surfaces. Plasticizer migration was characterized and explained from a thermodynamic perspective. Molecular simulations helped rationalize the impact of solvents on the interactions. The adsorption of an active substance was function of the interface properties.
