As many of you likely know, IV's are an important part of modern medicine. As more and more people go into space for longer periods, I would imagine it may become necessary for an IV to be administered in space. It doesn't seem initially that this would face a lot of challenges to be performed in zero gravity from a mechanistic point of view since many IV's use a pump to control flow rate.

Is there any history of IV's either being administered or tested on a person or skin+vein stand-in? If not, is there a reason other than lack of interest?

The first IV in space was performed on Space Shuttle Mission STS-55 in 1993.

Harris, a medical doctor, set up first I.V. (intravenous) line in space, injecting Schlegel with saline as part of study to replace body fluids lost during adaptation to weightlessness. Other payload crew members also participated.


Info on Bernard Harris and Hans Schlegel.

There's a whole IV section in the ISS Medical Checklist.
