    28: What is the infectious risk of arterial catheters?

    Dr. Ben Weaver and Dr. Elisa Walsh (@elisacwalsh) from Massachusetts General Hospital join the show to discuss the literature around the infectious risk of arterial catheters and the role of barrier precautions.

    This is the first episode produced from a new podcast elective that’s available to MGH anesthesia residents. Special thanks to Dr. Saddawi-Konefka for supporting the initiative.

    Thanks for listening!
