Guidelines/Instructions
TBI: Choose one. GENERAL: Choose one. Second insults may be systemic (extracranial or intracranial). Second insults aggravate processes of secondary damage in a brain already rendered vulnerable by the primary injury. The occurrence of second insults occurring before hospital admission in patients with more severe injuries, is frequent: oxygen saturation below 90% is found in 44 to 55% of cases and hypotension in 20 to 30%. The occurrence of second insults is strongly associated with poorer outcome. Hypoxia, hypotension and inadvertent hypocapnia are the most frequent causes of jugular desaturations, and periods of low brain tissue oxygen tension. The depth and duration of systemic second insults during the clinical course is related to poorer outcome.
