简要总结
Subarachnoid haemorrhage affects approximately 8000 people per year in the UK. The average age of a patient with subarachnoid haemorrhage is 50 years, although it is often seen in younger people (25-45 years). Despite modern medicine, the death and disability rate remains high both from the initial bleed and from the associated complications such as vasospasm. This is characterised by neurological impairment seen following the bleed. Despite modern treatment this is still associated with a poor outcome. This has significant implications due to the long term intensive neuro-rehabilitation these patients will require.
A recent study has shown that placing a small drain in the lower back following a subarachnoid haemorrhage may reduce the chance of vasospasm occurring and result in a better outcome. This trial was not optimally performed and so a trial is needed to look at this in more detail. The investigators have set up such a trial in our neurosurgical unit. If the investigators confirm that there is an improvement in patient outcome, it will change our practice in the future.
详细描述
All patients who present to our department with proven aneurysmal SAH and fit the inclusion criteria (see below) will be approached for inclusion into the trial. Written informed consent will be sought prior to recruitment into the study. Written assent from the patient's relatives will be sought in those cases where neurological impairment prevents written informed consent being obtained from the patient. The patient will subsequently be randomised into the control arm or the study arm of the trial. The control arm consists of normal therapeutic intervention, including external ventricular drainage if required for hydrocephalus. Those randomised to the therapeutic arm will have a lumbar drain inserted and set to drain CSF at 5 ml/hour. This will continue until CSF is no longer blood stained or until day 10 following insertion.
Primary outcome measures:
- Incidence of delayed ischaemic neurological deficit. This is defined as new neurological deficit and/or impairment of consciousness without other identifiable cause at least three days post haemorrhage.
New impairment of consciousness is defined as a drop in the Glasgow Coma Score of 1 motor point or 2 verbal/eye opening points.
