Unanswered clinical questions
Al Shahi et al recommend 'that cases (suspected subarachoid
patients) should at least be discussed with a specialist at a neuroscience
before the procedure (lumbar puncture)'. Do the neurologists or
really want to be burdened by consults before every lumbar puncture for
patients with CT-negative severe headaches?
The article also fails to provide any guidance on patient selection
intervention. In our experience, which may not be exclusive, there appears
much variability in the acceptance criteria. Although the World Federation
Neurological Surgeons (WFNS) grading scale is potentially useful for
selection, a recent observational study showed that only 60% of patients
admitted to a neurosurgical centre with SAH fell into WFNS grade I and II
implying that the WFNS scale was not the only defining criteria for
for neuro-intervention. Would the authors clarify their acceptance
