Description

Servadai reviewed prognostic factors in adults who develop acute subdural hematoma after severe head injury. This can help identify those patients who may require more aggressive management and monitoring. The author is from Ospedale M. Bufalini in Italy.


 

Parameters:

(1) age

(2) pupillary responses

(3) Glasgow coma score (GCS)

(4) presence of a lucid interval with coma

(5) post-operative intracranial pressure (ICP) monitoring

(6) hematoma volume (CT scan)

(7) midline shift (CT scan)

(8) intradural lesions (contusions, etc.) (CT scan)

(9) compression of basal cistern (CT scan)

(10) treatment facility

where:

• There was conflicting data on the impact of age. I tried to set values as best I could.

• The size of the midline shift varied in different studies.

 

Other factors that may affect prognosis:

(1) The interval between injury and treatment has been reported by some to affect prognosis, but the type of treatment center appears to be more important.

(2) The type of surgical procedure may affect outcome but no clear pattern was identified.
