Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Interventional
Description of intervention(s) / exposure
Surgery with corticosteroid (dexamethasone) oral capsule administered 4mg four times a day for 3 days and then reduced to 2mg three times a day for a maximum of 2 weeks. First dose is administered after onset of general anesthesia.

Eligibility
Key inclusion criteria
All patients aged 18yrs or more with demonstrated chronic subdural haematoma (CSDH) (either on CT or MRI or both) that is considered by the admitting neurosurgical team to be the cause of the patient's presenting symptoms and/or signs, and to be amenable to neurosurgical management will be considered suitable for study. All patients with diabetes mellitus will be discussed with an endocrinologist prior to commencing corticosteroid (CS).
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Children less than 18yrs will be excluded because the nature of CSDH in this group is entirely different to that observed in adults. Pregnant women will be excluded because CS can cause congenital malformations. Patients with a history of psychosis will be excluded because CS can provoke relapses.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a double-blind study with patients receiving identical matching capsules of either dexamethasone or placebo. The interventions are sealed in sequentially numbered identical containers according to the allocation sequence. To ensure allocation concealment, the contents (powders) of the capsules will also be identical in texture, odor and colour.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation is by a formulated permuted block with varying block sizes in a 1:1 ratio.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
Corticosteroids (CS) are anti inflammatory agents and are frequently used in neurosurgical and neurological
practice: they are a routine adjunct to surgery in patients with brain tumours worldwide.

Several clinical studies have also demonstrated the utility and safety of CS as an alternative to surgery with CSDH: however, most studies have merely compared CS as ‘medical versus surgical management’. Only one study has directly compared the effects of CS as an adjunct to surgery: although a null effect was observed, the ‘surgery alone’ group consisted of only 13 subjects; and the study was not randomised.

We propose to perform the first prospective, randomized, placebo-controlled double-blind clinical study of surgery for CSDH with and without corticosteroids as an adjunct. We aim to see whether surgery plus CS might reduce operative recurrences, in-patient stay and mortality.
