hi i was admitted into hospital yesterday and as much of a needle phobe i am im a bit concerned that as my veins on my left arm/hand wouldnt take any cannulae or butterfly needles after many attempts the doctors described my veins as blown. on my right side some access was possible but not on my hand but now the cannulae are starting to come out and every 2-3mins due to the awkward angle they have been inserted (the only veins which work) my infusion pumps keep beeping and going on hold not helpful as they contain my aminophylline and salbutamol! ive been told that im going to have to have the cannulas replaced. i have a few questions: can blown veins repair themselvves?and are cannulae in feet suitable? sorry for the length of the post.
