Which coating is used on Maquet Softline to optimize its function?

The choice of hydrophilic properties with a non-heparin coating for the Maquet Softline reflects an important aspect of perfusion technology aimed at minimizing thrombus formation and optimizing blood flow dynamics. A hydrophilic coating enhances the surface's interaction with blood, reducing the likelihood of protein and cell adhesion, which can lead to clot formation.

This type of coating is specifically designed to maintain smooth blood flow by lowering friction, which is beneficial in both cardiopulmonary bypass settings and other surgical applications. Furthermore, the absence of heparin in this coating means that while the surface is optimized for reduced thrombogenicity, it does not introduce any anticoagulation effects that might complicate the management of patient anticoagulation levels, thus allowing for easier control during surgery.

In contrast, hydrophobic properties typically increase the risk of protein adsorption and thrombosis, cationic coatings can lead to unwanted interactions with blood components, and silicone-based coatings, while offering some lubricity, may not provide the same level of performance in terms of reducing thrombosis as a hydrophilic, non-heparin coating. Therefore, the use of hydrophilic properties with a non-heparin coating is crucial for optimizing the functionality of the Maquet
