The effect of blood volume replacement on the mortality of head-injured patient.

Abstract

In 77 head-injured and transfused patients, the amount of blood volume replacement (BVR) and patient outcome were retrospectively analyzed. They were divided into four groups of intracranial lesion by initial CT; acute subdural hematoma (SDH) with or without other lesions, traumatic subarachnoid hemorrhage only, epidural hematoma only and all other lesions. Result shows SDH is the most vulnerable to massive transfusion and BVR more than 5000 ml was fatal. Patients with other lesions have high possibility of survival even if BVR amounts to 7000ml. It is concluded, for patients resuscitated with excessive amount of transfusion (> 5000 ml), follow up CT and some vigorous treatment such as administration of hypertonic solutions should be scheduled.
