Need to avoid bias in controlled trials EDITOR,-It is accepted practice that in all quantitative research statistical tests should be used to estimate the likelihood that findings arose by chance and that authors should avoid overinterpreting data where these tests suggest that the likelihood is high. It is also accepted that to avoid bias in the analysis of randomised controlled trials clinica...
متن کاملBlood velocity in the middle cerebral artery and regional cerebral blood flow during carotid endarterectomy.
Blood flow velocity in the middle cerebral artery, determined by transcranial Doppler ultrasonography, was monitored during 31 carotid endarterectomies. Electroencephalogram (EEG) was also monitored, and regional cerebral blood flow (rCBF) was measured. The relation between rCBF and mean velocity was dependent on the rCBF level; the correlation was strong if rCBF was less than 20 ml/100 g/min b...
متن کاملCerebral blood flow velocity during neonatal seizures.
AIM To determine if cerebral blood flow velocity increases during all types of neonatal seizure, and whether the effect is due solely to an increase in blood pressure, transmitted to the cerebral circulation when autoregulation is impaired. METHODS Seizures were diagnosed in 11 high risk neonates using cotside 16 channel video-EEG polygraphy. EEG, cerebral blood flow velocity (CBFV) using tra...
متن کاملCerebral vasoreactivity in unilateral carotid artery disease. A comparison of blood flow velocity and regional cerebral blood flow measurements.
BACKGROUND AND PURPOSE Hemodynamic information obtained by assessing cerebral vasoreactivity is of clinical interest and may have prognostic significance in patients with occlusive carotid disease. The aim of this study was to compare the results of transcranial Doppler and regional cerebral blood flow studies when used to assess cerebral vasoreactivity. METHODS Blood flow velocities in both ...
