Intracranial Pressure Assessment

Intracranial pressure (ICP) monitoring is an important component of brain monitoring. Numerous methods for measuring ICP in animal models have been described, including the use of epidural monitors and subdural, ventricular, parenchyma, cisterma magna catheters, and lumbar cerebrospinal fluid pressure. The ventricular catheter method is considered to be the gold standard for measuring ICP. Here, we introduce a method to monitor ICP in rats using an ultraminiature fiber optic transducer placed into the lateral ventricle. The details of procedures, along with applications, advantages, and limitations are discussed here.
