Hi Jackie!
My son, Gabe, does not have hydrocephalus. He does however have a programmable shunt. Gabe has craniosynostosis, chiari malformation and pseudo tumor cerebri. To treat the PTC he has a shunt. His shunt is a lumbo peritoneal (LP) shunt. It goes from the lumbar region of his spinal column to his belly and drains the excess CSF there.
Programmable shunts are wonderful. Before programmable shunts, every time they had to adjust how much a child was draining they would have to go in and surgically change out the components of the shunt. Thus lead to an increased risk in infection (meningitis) and more scar tissue. I believe that there are only 2 types of programmable shunts on the market right now, I could be wrong though. Programmable shunts allow the shunt to drain more or less CSF by “reprogramming” it. Our shunt uses a programmer with a large magnet that plugs into the wall. We are able to place the transmitter over the dial and reprogram Gabe’s shunt to a higher or lower number. Our shunt it set up with the higher the number on the programmer the less fluid that is drained off, lower the number the MORE fluid that is drained off.
At least for PTC when they insert the shunt they set it at a certain level. For us they wanted us to wait a month before we started adjusting the pressure so that Gabe could accommodate to the shunt. After the first month we then started adjusting his shunt with the programmer. We are able to do ours at home as we have a programmer. (I am also a nurse) Some doctors want the kids to come into the clinic to have it done. Older kids are able to be a little more verbal and if they are not verbal they are physically doing more that allows the parents to gauge how the shunt is working. In a baby that can be hard.
I would assume that they want the baby to come to the hospital so that they can watch how she responds to the new pressure setting. A change in pressure can cause low pressure symptoms which are worse than high pressure symptoms. Finding the right setting is a slow process. It is one of many “ups and downs” and I can only imagine in a baby how much more difficult it is to figure out. My son is able to tell me and is able to figure out what is high pressure and what is low pressure. Do we need to go higher or lower on the programmer. We are very fortunate to be in close contact with our neurosurgeon via email at all times also.
Unless your niece is having complications that is putting her into the hospital post re-programming I would try not to worry. For a baby to assess for how the shunt is working is a watch and see what she starts doing. Meeting milestones, ect.
Good Luck to your niece.

We also use Dr. Frim. One of his passions is hydrocephalus. He uses a lot of the programmable shunts.
