Background. Cerebral blood flow is affected by painful stimuli, and analgesic agents may
alter the response of cerebral blood flow to pain. We set out to quantify the effects of …

Remifentanil (Ultiva™), a fentanyl derivative, is an ultra-short acting, nonspecific esterase-
metabolised, selective μ-opioid receptor agonist, with a pharmacodynamic profile typical of …

PURPOSE: The aim of this study was to investigate the effect of remifentanil continuous
infusion on the blood flow in rabbit oral tissue during propofol and sevoflurane anesthesia …

Significance The optical measurement of cerebral oxygen metabolism was evaluated. Aim
Compare optically derived cerebral signals to the electroencephalographic bispectral index …

Animal studies have shown that opioids modulate the function of dopaminergic neurons.
The effect of alfentanil on cortical and thalamic binding of the D2/D3 receptor ligand [11C] …

Remifentanil is increasingly used in the context of anesthesia, eg, in patients presenting for
MRI examinations, not only as an analgesic but also to replace nitrous oxide. Therefore, a …

OBJECTIVES: The purpose of this study was to investigate the effects of naloxone and
phentolamine on the blood flow changes in rabbit oral tissue induced by remifentanil during …

Many cases of muscular ischemia do not manifest without increased metabolic demand.
Hence, diagnosis of intermittent claudication often requires inducing physiologic challenge …

Objective To study the effects of a high remifentanil bolus dose on pig's
electroencephalographic indices and on brain regional and global oxygenation. Study …

The aim of this study was to investigate the effect of remifentanil infusion on oral tissue blood
flow including submandibular gland tissue blood flow (SBF) and internal carotid artery blood …
