Licox, Integra Lifesciences Corporation, Plainsboro, NJ, USA Brain tissue oxygen monitoring system with intraparenchymal oxygen sensor.LabChart ADInstruments, New South Wales, AustraliaīrainVision Recorder BrainProducts GmbH, Munich Electrode 1 of the strip electrode serves as ground. This is customary practice for intracranial pressure (ICP) and tissue partial pressure of oxygen (p tiO 2) monitoring.ĪDInstruments, New South Wales, AustraliaĮlectrodes 2-6 of the strip electrode are connected in sequential unipolar fashion to this amplifier, each referenced to an ipsilateral subgaleal platinum electrode. Here, it is also possible to place a subdural electrode strip through a burr hole, or to monitor with an intraparenchymal electrode array (Spencer, 1.1mm diameter, Ad-Tech, Racine, WI, USA) that is placed through a burr hole or a multi-lumen bolt. Antibiotic treatment beyond standard preoperative prophylaxis is not recommended. an additional fully penetrating skin suture should be performed with some distance to the scalp exit point, and a sufficient amount of absorbable hemostatic gelatin sponge should be placed under the bone flap - particularly in the area of the strip.the subcutaneous tunnel should be made sufficiently long and dilated, e.g.no plating hardware should be used next to the location of the strip and.the tail of the strip should exit the craniotomy and scalp in line with the rest of the electrode, and not be curved or bent at an angle.a sufficient bone should be removed with an osteotome or rongeur where the tail of the strip exits, and through which the electrode can be withdrawn by gentle traction at the end of monitoring.Therefore, the following precautions should be taken: Gentle traction may not be sufficient to remove the strip after the monitoring period when it is trapped/pinched by the bone flap or the titanium fixation, or if the subcutaneous tunnel is too tight.Ī cerebrospinal fluid (CSF)-fistula may develop.
