I would love some input to an issue we are having with infustion set sites. My son has been on the pump for 5 months now and we have been having a reoccuring problem the whole time with what seems to be the infusion set getting partially or fully blocked when inserted. We insert them in either his arms or the backside. These are really the best options we have because of his body type. Kyle is very lean and muscular (lean muscle, not bulky, but hardly any fat), and his legs and stomach are very tight, and all we feel is muscle in those areas. To make a long 5 month story short we have had prolems with a lot of his sets not working mostly during boluses. The basal seems to absorb well but the boluses are hit or miss. If we have a "good" site inserted his BG are great staying around 100 for the most part. But other times we have consistently high BG after boluses or corrections (250-350) where a shot immediately lowers the Blood sugar, and the basal seems to maintain him, but we have to either keep giving a shot for the bolus or change the set. For this reason we have been changing sets much more than we should have to be, sometimes once a day because they just aren't working. It has been determined that even in his bottom and arms, the site is hitting muscle tissue (or maybe scar tissue) and partially blocking the flow of insulin. This isn't just once in a while, this is probably close to half the time. We have tried the Sure T and the Mio sets. The Mio gave us No Delivery alarms, but when I pull the site it is not bent or kinked and I can easily see insulin coming through it. (We only tried a couple of Mios though) The sure T's don't give us alarms just consistent High BG when they aren't working. The nurse educator we are working with said the Sillhouette might be best for his body type, but Kyle will NOT try those...he doesn't like the look of it. He said the needle that inserts it looks too long a scary, and that he would go back to shots before using those. The other day we had a No Delivery alarm at breakfast, forcing us to unexpectidly change the site and making him late for school. He refused to put another set in him and I ended up giving him Lantus and doing shots for a couple of days. So that is how frustrated he is getting. He loves the pump though and asked if we could give in another try. I am looking for ideas that might help reduce the amount of problem sites we have to go through so he doesn't end up giving up on the pump. I know failed sites are a part of pumping, and I can't eliminate them, but this is a VERY regular problem, not just every once in a while. And Kyle's body type can't be that uncommon...lots of kids are lean like him so I don't understand why we are having such a problem. Or am I expecting too much and this is just a typical experience? I don't post much but I know this is the best place to come for ideas, and I always appreciate all the help I get from everyone here!
