As with most things in life, with practice come efficiency, confidence and ease. Well, usually. Some days, however, everything that can go wrong, does go wrong. So here is my step-by-step guide of how NOT to change your pump site.
First, gather all of your site change supplies. Forget that this doesn't include one kitty cat who is in full-blown "play with me" mode. Also forget that this DOES include your bottle of insulin.
Open IV Prep wipe and place on bed. Watch cat lick wipe. Throw away wipe, open new one, and swab insulin bottle and hip. (Also say a little prayer that cat's system can handle a lick from an IV Prep wipe.) Insert insulin bottle into reservoir and begin to fill. Drop on floor and watch it roll under the bed. Watch cat run under to swat her new "toy". Crawl under bed to retrieve and admire all the pretty little bubbles. Spend a significant amount of time getting bubbles out.
Attach reservoir to site tubing. Try to remove plunger, only to find it must be glued on because it isn't coming loose. Struggle with it while trying not to add bubbles back into the reservoir. As you are doing this, try to keep cat from swatting joyfully at the dangling tubing and site.
Finally ready to prime? No, because you didn't rewind your pump yet. Wait
Thankfully, it's now time to put site in the inserter and finish things up. Don't forget to be too gentle when pushing the inserter's buttons, so site only goes partially into you. That's lots of fun. Try to peel somewhat stuck tape off body and insert again.
At last, success. New site is in. Blood sugars are stable. Cat has had enough fun for one day and goes to take a nap. Be glad you only have to do this every three days.
