Mortality and Prehospital Blood Pressure in Patients With Major Traumatic Brain Injury Implications for the Hypotension Threshold

摘要

IMPORTANCE Current prehospital traumatic brain injury guidelines use a systolic blood pressure threshold of less than 90 mm Hg for treating hypotension for individuals 10 years and older based on studies showing higher mortality when blood pressure drops below this level. However, the guidelines also acknowledge the weakness of the supporting evidence.
