Excerpt
Elevated intracranial pressure (ICP) has been associated with increased mortality in patients with severe traumatic brain injury (TBI). More than 20 years ago, Marmarou [
1], while analysing the data from the traumatic coma data bank (TCDB), recognized that the proportion of hourly ICP readings greater than 20 mmHg was fundamental in explaining long-term outcome in TBI victims. Since that moment, the cutoff point of 20 mmHg has been selected as most indicative in neurotraumatology. Not only times spent over the threshold, but also the responses to the therapy are crucial. Following this concept, Treggiari [
2] systematically reviewed the literature to estimate the association between ICP patterns and outcome. Confirming Marmarou’s observations, raised ICP, i.e. an ICP >20 mmHg, was associated with an increased probability of death. Moreover, if ICP was raised but treatable, this condition was associated with a threefold to fourfold increase in the probability of death or poor neurological outcome. If ICP was raised and refractory, this was associated with a dramatic increase in the relative risk of death (OR 114.3). Therefore, refractory ICP and response to ICP treatment could be better predictors of neurological outcome than absolute ICP values. …
