Randomized Controlled Trial Clinical Trial
A pilot study of changes in cerebral blood flow velocity, resistance, and vital signs following a painful stimulus in the premature infant.
The purpose of this pilot study was to determine the cerebral blood flow velocity and resistance changes and vital signs following a painful stimulus in the premature infant. ⋯ This is a study based on a small sample size. However, the Doppler-measured peak systolic velocity increases significantly after a painful stimulus. The clinical implication of this finding needs to be established.
