Intracranial pressure (ICP) monitoring is one of the most important patient monitoring in neurosurgical field. In acute stage, although ICP of the post-operative period were controlled well, the clinical results were variable. Authors monitored ICP and brain compliance after the operation. And analyzed the correlations between the ICP and brain compliance and patient clinical outcomes.

Seven intracranial hemorrhage patients were included in this study. There were 5 males and 2 females patients (mean age: 47.6y, ranged from 6 to 77 years). All the patients were underwent craniectomy, craniotomy and the burr-hole trephination (intracerebral hemorrhage; 2 patients, intraventricular hemorrhage; 2 patients, subarachnoid hemorrhage; 2 patients) and the Spiegelberg double lumen intraventricular balloon catheter was inserted in a fluid-filled catheter on the lateral ventricle. The data of ICP and compliance were collected. The 154 pairs of data were collected, and performed the statistical correlations.

The 154 sets of data were collected and analyzed. The average of ICP was 10.6±3.7 mmHg and the compliance was 0.56±0.15. The ICP was inversely correlated with the compliance (p=0.20). The compliance was not correlated with the patient's age and cerebral perfusion pressure.

From this study, authors thought that Spiegelberg double lumen compliance monitor was safe and reliable to check the ICP and brain compliance continuously. And we can conclude that brain compliance and ICP showed reverse correlation.
