Conference paper


The wick catheter was applied successfully to the measurement of the brain interstitial fluid pressure (BIFP) (I). BIFP is high within the edema fluid territory as compared to that of CSF and of normal brain tissue (6). This pressure gradient induces a propagation of the edema fluid into the surrounding extracellular space (7). The decrease in Hounsefield number in CT scan is directly proportional to the increased water content of the brain tissue and in turn reflects the intracompartmental pressure gradients (4). These recent developments led us to try the simultaneous monitoring of CSF pressure and the BIFP within the brain parenchyma of acute head injury patients, to compare with the printed-out Housefield numbers in CT scan. This study proposed to find out which of the internal or external decompression is more rational treatment in the early management of head injury.
