Study of pressure readings from existing brain drains

This trial looks at whether the fluid from your brain drain (called CSF) can help predict infections. It compares samples taken from different spots on the drain to find better ways to catch infections early.

This study tests a wireless sensor that measures fluid flow in a shunt (a tube that drains fluid from the brain) under different valve settings. It may help people with hydrocephalus who already have a shunt and a programmable valve.

This study tests whether using ultrasound (a type of imaging) to guide the placement of a brain drain (ventricular catheter) is safe and effective for patients with newly diagnosed hydrocephalus (fluid on the brain). If you're already scheduled for the procedure, you may be able to join.

This study compares different strategies for safely removing external ventricular drains—tubes placed in the brain to relieve fluid buildup and pressure after a brain bleed. The goal is to figure out which weaning plan works best and keeps patients safest.

This study tests a new sensor that measures brain pressure from outside the head. It is for people who are already in the hospital getting their brain pressure and blood pressure monitored continuously.

This study tests a new wireless device that measures fluid flow in a CSF shunt (a tube that drains fluid from the brain). You may join if you have a shunt under your skin across your collarbone and can use or be nearby the device for a month.
