Question

Why is death imminent after a brain injury for 6-year-old child that had a fall accident on a swing causing brain trauma with decreasing blood pressure?

Answer 1

Hypotension is a result of secondary insult to the brain after traumatic injury. hypotension and other secondary insult puts a detrimental effect on the final outcome of the patient.

it has been observed that a low level systolic blood pressure  at the time of hospitalisation is associated with high mortality. so according to the guidelines it is advised to maintain a threshold systolic BP of greater than 90 mm hg.

one of the major cause of death in these patient is brain hypoxia that is a result of hypo perfusion caused by hypotension, so an early and aggressive treatment of hypotension should be done in this case that is the readon why hypotension associated with brain injuries leads to such a grave condition.
