Isolated medulla oblongata function after severe traumatic brain injury.
The objective was to report the first pathologically confirmed case of partly functionally preserved medulla oblongata in a patient with catastrophic traumatic brain injury.A patient is described with epidural haematoma with normal breathing and blood pressure and a retained coughing reflex brought on only by catheter suctioning of the carina. Multiple contusions in the thalami and pons were found but the medulla oblongata was spared at necropsy. In conclusion, medulla oblongata function may persist despite rostrocaudal deterioration. This comatose state ("medulla man") closely mimics brain death.
