One of the more fascinating topics in these interviews is reading about how much tinkering and troubleshooting was necessary during the early days of dialysis. Access was a major issue; early on, one would cut down to find an artery and a vein in order to perform dialysis; at the end of the dialysis procedure, the vessels were ligated off and therefore those vessels could not be used again. Needless to say, there are only a limited number of arteries available to suppor dialysis, so other techniques were essential. One nephrologist describes making "home-made" catheters simply by cutting the appropriate length of polyethylene tubing and tapering off the end by holding it over a Bunsen burner. Because they couldn't afford real stainless-steel guidewires, they used guitar strings coated in silicone, which were much cheaper.
So: the next time you grab a catheter kit off the shelf and plug in the ultrasound machine, think about all the additional hassle involved in placing a dialysis catheter our nephrology fellow predecessors had to endure!
