General Anesthesia Versus Locoregional Anesthesia for Evacuation of Chronic Subdural Hematoma

NEURANESTH General Anesthesia Versus Locoregional Anesthesia for Evacuation of Chronic Subdural Hematomas: A Prospective Randomized Trial

This study compare general anesthesia versus locoregional anesthesia for evacuation of chronic subdural hematoma. Half of participant will be operated under general anesthesia, while the other half will be operated under locoregional anesthesia.

General anesthesia is the most common technique for this surgery. The local anesthesia is less common but it allows to obtain the same surgical result. This last technique being more recent little study compared these two techniques in terms of complications and postoperative consequences.

The investigators will randomize patients into two groups (a general anesthesia group and a locoregional anesthesia group).

General anesthesia provides complete immobility and optimal surgical comfort but is a source of multiple complications, especially in a population of polypathological and polymedicated elderly patients (which is the population affected by chronic subdural hematomas).

Locoregional anesthesia requires special technical training, leads to complete analgesia of the surgical procedure but does not involve complete immobility of the patient, however this technique probably leads to less postoperative complications and allows a more early rehabilitation.

Inclusion Criteria:

• subdural chronic hematoma uni or bilateral

Exclusion Criteria:

• Patients agitated or not cooperating, not allowing the realization of a locoregional anesthesia
• Patients with other intracranial lesions
