Several years ago I was working as an agency nurse on the 7p-7a shift and received an admit, a gentleman in his 40's with dx cp r/o mi, a&ox3. At this hospital the standard iv tubing was about 6 ft long with an extension set approx 18 inches long attached to the angiocath. After getting the pt settled, I pulled up a chair to his left and started entering the standard admission info into the laptop, his iv was in his right hand. Finished the admit in about 20 minutes and left to call the md for a clarification, tube orders to the pharmacy, etc. This probably took about 45 minutes. I went back to check on the pt and label the iv tubing, somehow the extension set had become disconnected distally to the site, blood dripping and what looked like about 2 units of clotted blood on the floor! Called the lab for a stat draw, changed the tubing, called the doc to report that the pt's hct had dropped by 3 pts and what had happened. Got the mess cleaned up, somehow the pt remained calm and went back to sleep shortly afterwards. Through the remainder of my contract, the first thing I did when I got a new admit was make sure that the iv tubing connections were super tight. When I think about what could have happened I get chills, in the incident report I suggested they get rid of that particular tubing, nothing changed. Does anyone else have a story to share?
