Six venous indwelling cannulas were observed under constant frame conditions (low osmolar solutions, constant infusion solution, prospective randomized study). There is a close correlation between the complication rate in the vein and quality of the material and puncture. The best results were achieved with Teflon cannulas. Here the condition of the transitional zone between mandrin and synthetic material was of special importance as well as the fact that the form stability also had to be guaranteed after application. The thrombotic dry weights of these cannulas, determined in animal experiments, yielded low values for polytetrafluorethylene (PTFE) or polyethylene (PE), but PTFE and PE cannulas have led to an increase of the thrombotic dry weight in 24 and 48 h of indwelling time.
在恒定框架条件下（低渗溶液、恒定输注溶液、前瞻性随机研究）观察了6根静脉留置套管。静脉并发症发生率与材料质量和穿刺之间存在密切相关性。聚四氟乙烯套管取得了最佳效果。在这里，芯杆与合成材料之间过渡区的状况以及应用后也必须保证形状稳定性这一事实都尤为重要。在动物实验中测定的这些套管的血栓干重，聚四氟乙烯（PTFE）或聚乙烯（PE）的值较低，但PTFE和PE套管在留置24小时和48小时后导致血栓干重增加。
