This week I had the most bizarre thing happen with my IV pump. I was running heparin via IV - an anticoagulant medication used to treat clots or potential clots in patients at risk for pulmonary embolisms or strokes among other things. Often heparin is a once or twice a day injection, but this patient needed it IV due to their circumstances.
At about 0500 I heard the IV beep telling me there was "air in the line." However frightening that sounds, it's really rare there is actually air in the line. The IV pumps are incredibly sensitive and even eensy-teenie-weenie bubbles that cannot cause harm to the patient will set it off- generally to the annoyance of everyone within a 5 mile radius. I went to look at it and jiggle the line that exits the bottom of the pump and noticed that it was wet!!!
I have now adopted my "everything is okay, I deal with type of stuff every single day" voice when in fact I have most likely never ever seen what I am witnessing actually happen EVER. I have to admit I'm not really sure where that tone of voice came from, because prior to being a nurse that tone never existed for me. I have never been a confident person, but wearing the scrubs seems to give me an alternate ego of Nurse Reese who will take care of you no matter what. I cannot even imitate myself in that voice when I'm out of scrubs!
Anyway, I calmly explained to the patient that I was going to clamp her IV and check the tubing. I unlocked the pump to visualize the tubing inside - again something I do actually do all the time. Instead, when I unlocked the pump the IV tubing fell into 2 pieces - it looked like it had been sliced in half with a pair of scissors! I thankfully reacted fast enough to grab the bag of heparin and turn it upside down before I had created too big of a heparin puddle on the floor.
I grabbed all new tubing, primed the line, and set the patient back up on the medication and then asked a more experienced nurse to look at my severed tubing. The nurse said, "Huh, I've seen children chew through their IV lines, but I have never, ever seen that happen." Awesome.
In the midst of this I had called lab for a stat PTT draw (the lab that tells us how well the heparin is working - the goal is to be within a therapeutic range), called the pharmacist to tell them what the problem was and that I would notify them as soon as I had the lab results for further orders, and talked to the doctor who happened to wander in during the middle of all this for report. My fear was that the patient had not been receiving enough medication and therefore was at risk for a repeat medical incident. However, all is well that ends well because in fact her PTT was a little too high -even with the leaking tubing- and pharmacy had me turn off the medication all together.
I don't think it was until 0730 that my heart rate came back down to normal. However, no one else was the wiser ;)
