Intracranial Pressure Monitoring in Patients with Fulminant Hepatic Failure Treated with Plasma Exchange and Continuous Hemodiafiltration

Background/Aims: To study the influence of our artificial liver support (ALS) on intracranial pressure (ICP) and to evaluate the significance of ICP monitoring in fulminant hepatic failure (FHF) patients treated with ALS. Methods:ICP was measured in 13 consecutive FHF patients treated with ALS. Maximum value in ICP every day was employed as ICPmax of the day. We analyzed the correlation: (a) between ICPmax and consciousness level; (b) between ICP and colloid osmotic pressure (COP), and (c) between ICP and PaCO2. Results: ICP in 11 patients of 13 was controlled <20 mm Hg through our ALS. A significant positive correlation between ICPmax and consciousness level was found (p < 0.01). Although there was a significantly negative correlation between ICP and COP (p < 0.001), there was no correlation between ICP and PaCO2. Conclusions:We conclude that our ALS does not have any adverse effects on ICP and that ICP monitoring is one of the inevitable monitorings in the management of FHF.
