Abstract
The present study included 50 patients with head trauma there were 34 male (68%), and 16 female (32%). The main aim of this study was directed to investigate the impact of hypotension and hypoxia as causes of secondary brain injury in determining the outcome of patients suffering from moderate and severe head injury in the Emergency Department (ED).
Our study which was conducted on 50 patients, specifically to describe the frequency and the duration of hypotensive and hypoxic events in the early resuscitative phase following moderate to severe head injury Using an SBP of lower than 90 mm Hg to define hypotension and a SaO2 of 92% or lower to define hypoxia, Also ONSD measured for ICP, The mean age of all enrolled patients was 46.06 years. The percentage of male (68%) was higher than female (38%) data was collected after clinical assessment which including neurological examination using GCS, laboratory investigations, instrumental and imaging evaluation from injury through resuscitation were analyzed for the 50 patients on admission within first 24 hours of injury. from the total of 19 died patients (38%), of them 8 patients (16%) died had hypotension. And regarding the contribution of hypoxia to mortality found that 3 patients (6%) died had hypoxia only, and 8 patients (16%) died had both. Thus found that hypotension was main contributor on deaths and associated with strong relation with severity of GCS less or equal 8 and increasing measurement of ONSD rising more than 5mm indicate rising ICP.
