Re: [IPp] Infusion Set Cannula Length

I think it is entirely possible that is the problem.  Our daughter could 
tell if it felt "funny" when it went in and I suspected a similar problem. 
Since the canula is not kinked it could be that the site is going in just 
far enough to get real close to the muscle.  We now use infusion sets that 
go in at an angle because we often ran into that problem.  I am sure they 
will swap out unopened boxes if it hasn't been too long.  Just use the 
longer canula sets for areas with more fatty tissue.  Sometimes scar tissue 
can develop if you aren't rotating your sites far enough apart, that too 
will cause undesireable absorption.  Good luck, Suzanne
