Fundamentals of Critical Care Support (FCCS) Practice Test

The volume of an epidural hematoma that necessitates surgical evacuation, regardless of the patient's Glasgow Coma Scale (GCS) score, is typically recognized as 30 mL. This threshold is significant because even a hematoma of this size can lead to increased intracranial pressure and potential deterioration of neurological status. Surgical intervention is essential to prevent further complications such as brain herniation, which can occur as the mass effect of the hematoma grows.

In clinical practice, while GCS is an important factor in assessing a patient's neurological status, the volume of the hematoma is a critical determinant for surgical intervention. When a hematoma exceeds this 30 mL volume, the risk of adverse outcomes rises significantly, prompting the need for surgical evacuation to relieve pressure and mitigate damage to brain tissue. Thus, this volume serves as a guideline that underscores the urgency of treating larger hematomas, ensuring better patient outcomes.
