Total 60 patients with the history of traumatic brain injuries having Glasgow Coma Scale 0.5cm was taken as a surrogate for elevated intracranial pressure (eICP) and a predictor of CT findings of sub arachnoid hemorrhage (SAH), subdural hematoma (SDH), extradural hematoma (EDH) and cerebral edema (CE).
Whether the patient required surgery or not was also compared with our data of elevated intracranial pressure (eICP) deduced from optic nerve sheath diameter (ONSD).
Other recent studies in this regard used the universal 20mmHg eICP threshold for reference of eICP and checked the range of ONSD which happened to be 0.48-0.70 cm10,11 which were comparable to our results.
The CT revealed features of an elevated intracranial pressure (EICP).
An increasing evidence base suggests that ultrasound of the OSND is a simple and sensitive way of assessing for the presence of EICP. Primary research by Hansen and Helmke showed a correlation between rising cerebrospinal fluid (CSF) pressure and ONSD .
(20) The EICP covered the EU15 until April 2004 and the Eu25 thereafter.
The CPI-U is published on a 1982-84 = 100 basis, the EICP on a 1996 = 100 basis.
These are the MUICP and the EICP, based on the HICP estimated by each NSI of the EU.
But since the calculation of MUICP, the EICP is calculated as the weighted average of MUICP and HICP of countries that do not belong to EMU (Denmark, Sweden, and the United Kingdom).
