Elevated intracranial pressure (ICP) is significantly associated with high mortality rate in severe head injury (SHI) patients. However, there is no absolute agreement regarding the level at which ICP must be treated. The objective of this study was to compare the outcomes of severe head injury patients treated by setting the ICP threshold at >or=20 mm Hg or >or=25 mm Hg. ⋯ This study supported a recommended ICP threshold of 20 to 25 mm Hg in SHI management. However, in cases with an absence of basal cisterns on initial CT scan, the probability of good outcome may be higher using an ICP threshold of >or=20 mm Hg.
