Abstract

Abstract: PURPOSE: To modify the classical double-syringe system (DSS) method and to make it capable of producing more stable foam. METHODS: 1% polidocanol(POL) foam was generated by DSS method and modified DSS method, respectively. In modified DSS method, one syringe was replaced by a self-made elastic gasbag. The procedure for modified DSS was as follows: drew 2 mL POL liquid and 8 mL air into the syringe; connected the syringe to a three-way tap with a fixed gasbag in a straight line; pushed the syringe plunger 20 times. The stability and uniformity of foam produced with two methods were compared using foam half-time (FHT) and optical microscopy, respectively. The change of foam volume in modified DSS method was also detected. The quality of foam produced by modified DSS method whether three-way tap was twisted was compared. GraphPad Prism 8.0 software package was used for data analysis. RESULTS： Replacing one syringe in the DSS method with an elastic gasbag could produce more uniform foam with longer FHT, which maybe related to foam volume compression. At the same time, the foam quality could be further improved by twisting the three-way tap in modified DSS method. CONCLUSIONS： Replacing one syringe in the DSS method with an elastic gasbag could produce more stable foam.
