A catheter for draining body fluid that includes a tube for draining the fluid that has an outside surface, an inside surface, a tip and defines a lumen therein. The tip includes at least one opening therein that is in fluid communication with the lumen, at least a first sensor configured to measure the oxygen partial pressure in brain tissue positioned on the outside surface of the tube at a first location, and at least a first wire having a proximal end and a distal end. The distal end is in electrical communication with the first sensor and the proximal is configured to be in electrical communication with a monitor. The tube and the first sensor can be inserted into a single hole in a patient's cranium. |
