Non-invasive monitoring of intracranial pressure waveforms using Braincare® BCMM 2000 monitor in dogs with myelopathies undergoing myelography

ABSTRACT: Intracranial pressure (ICP) monitoring is considered the gold standard for optimizing treatment of humans in intensive care units. However, this procedure not commonly performed veterinary medicine because limitations and complications method. There are some new promising non-invasive techniques ICP, but they have been validated medicine. This study aimed to correlate intracranial (NI-ICP) waveforms obtained with BCMM-2000 Brain4care monitor during myelography dogs myelopathies undergoing exam diagnostic purposes through invasive subarachnoid (SP). The NI-ICP waveform was monitored six before (M1), (M2), after (M3) contrast medium injection into space. Cerebrospinal fluid (CSF) collected injection. SP simultaneously three dogs. Correlations between two methods were using Pearson’s coefficient. analysis morphology amplitude waves at each moment performed, M2, an increase P2:P1 ratio (p<0.05) observed both methods. In M3, values similar those M1, demonstrating return cerebral compliance. comparison had a positive correlation moments (Pearson’s coefficient r=0.76; p=0.027). speed administration, degree spinal cord compression, volume CSF previously may affect ICP dynamics. effective detecting changes dynamics abnormal pulse meningoencephalitis unknown origin, vertebral neoplasm intervertebral disc disease without hemorrhagic myelomalacia, suggesting increased induced by myelography.
