I inserted a foley catheter on a spina bifida pt and I set up the procedure table and my sterile field. I did everything as I was instructed. I advanced the foley and stopped when I met resistance. I asked the pt to relax because I felt him tense up. When he relaxed I was able to advance the 16Fr 5cc foley further. I felt when I passed the sphincter and noted urine in the tubing. After noting urine in my tubing I advanced the foley 2 more inches. And as I was inflating the balloon with 10cc (thats what the order called for) the pt started tensing up and once I removed my syringe from the port I slightly tugged at the foley to make sure that it was at the neck of the bladder. I looked down at the pts member and blood was leaking from around the entrance of the foley and then blood started flowing thru the tubing. I don't understand. I done the procedure the way I was taught and the same way that I have inserted any other foley. Can someone please give me some input. Has anyone ever experienced this before?
