Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Chronic subdural hematoma

Intervention(s):

Group I - Atorvastatin (Experimental): Atorvastatin and, Conventional treatment. The atorvastatin will be administered 20 mg daily orally for 8 weeks, starting on the first postoperative day. The Conventional treatment will be administered in the same way of the group IV. Group II - Dexamethasone (Experimental): Dexamethasone and Conventional treatment. Dexamethasone will be administered for 4 weeks in the following scheme: The first three days (starting on the first postoperative day) one vial (4 mg) will be administered intravenously every 6 hours; from day 4 to 6, one vial (4 mg) every 8 hours intravenously; on day 7, one vial (4 mg) every 12 hours intravenously; From day 8 to 10, one tablet (4mg) will be administered orally every 12 hours; and from day 11, one tablet (4 mg) will be administered orally daily until the treatment is completed. The Conventional treatment will be administered in the same way of the group IV. Group III - Atorvastatin and Dexamethasone (Experimental): Atorvastatin, Dexamethasone and Conventional treatment. The Atorvastatin will be administered in the same way of the group I, the Dexamethasone will be administered in the same way of the group II and, the Conventional treatment will be administered in the same way of the group IV. Group IV - Conventional Treatment (Control): Conventional treatment (supine position in the Fowler position at 30 to 40º, 100% supplemental oxygen, basic hydration, antimicrobials, anticonvulsants, analgesics, gastric protection) during hospital admission (7 days).

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

1. Reduction in the volume of the subdural hematoma (It will be evaluated as “Yes” when the volume in mL of the current Computed Axial Tomography decreases with respect to the initial evaluation and “No” in any other case). Measurement time: At baseline, at the 7th day and at the month. 2. Reduction in recurrences of subdural hematoma (by Computerized Axial Tomography; Yes, No). Measurement time: At baseline, at the 7th day and, at a month.

Key secondary outcomes:

1. Visualization of the membranes (Yes, No). Measurement time: At baseline, at the 7th day and at the month. 2. Collection index (numerical value). Measurement time: At a month and at 4 months. 3. Decrease in the rate of reinterventions (Yes, No). Measurement time: At a month and 4 months. 4. Reduction in operative morbidity (Yes, No). Measurement time: upon hospital discharge. 5. Survival (alive, dead). Measurement time: At hospital discharge and, At a month and 4 months. 6. Clinical prognosis (according to the Glasgow outcome assessment scale: 1) favorable (good recovery, if the patient returns to his pre-trauma activities free of sequelae or with minimal sequelae; moderate disability, if sequelae that do not allow the patient to reintegrate to his previous activity, but allow him an independent life); 2) unfavorable (severe disability, if the patient requires the assistance of another person for care; vegetative state or death)). Measurement time: At hospital discharge and, At a month and 4 months. 7. Clinical Adverse Events (AEs). They will be measured as: -Occurrence of AE (Yes, No), -Description of the AE (name of the event), -Intensity of the AE (mild, moderate, serious), -Causal relationship (unrelated, doubtful, possible, probable, definitive), -Measures adopted (None, Administration of any pharmacological therapy, Addition of a non-pharmacological therapy, Exit from the study, Hospitalization / prolongation of hospitalization), -Result (Completely resolved, Resolved with sequelae, Conditions in improvement, Present condition and unchanged, Worsening, Death caused by this event). Measurement time: daily during hospital admission and, At a month and 4 months. 8. Laboratory (numerical values of hematological and blood chemistry tests: blood count, hematocrit, leukogram with differential, platelet count, coagulogram, bleeding time, prothrombin time, coagulation time, blood gases, ALAT, ASAT, blood glucose, creatinine, lipidrogram, inogram, among others). Measurement time: At baseline, on the 7th day (at discharge) and, At a month and 4 months
