Ensuring Long-Term Rodent Catheter Patency with Proper Selection and Care

Life Sciences, Drug Discovery & Development, Preclinical,
  • Wednesday, August 05, 2020

After research model surgery and catheter implantation, the long journey of catheter maintenance and patency begins. The completion of a great surgery is only the beginning of a successful study, while protecting and accessing the catheter or device post-surgery is often undervalued by the research community. During this presentation, the speaker will review some essential procedures to aid in keeping catheters patent for longer periods of time. The speaker will discuss situations when using a catheterized model would be beneficial, various catheter materials and their uses, different methods for exteriorizing the catheters, recommended flushing and locking solutions, as well as frequency of flushing and troubleshooting a problematic catheter. The presentation will conclude with some tips and tricks to make it easier to use a catheterized rodent model.
