Transcranial Doppler ultrasonography (TCD) was introduced in 1982 by Aaslid and
colleagues5 as a non-invasive technique for monitoring blood flow velocity (FV) in the basal …

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

Summary Abstract Remifentanil (Ultiva™), a 4-anilidopiperidine derivative of fentanyl, is an
ultra-short-acting μ-opioid receptor agonist indicated to provide analgesia and sedation in …

Background Hypercapnia abolishes cerebral autoregulation, but little is known about the
interaction between hypercapnia and autoregulation during general anesthesia. With …

Background and aim: Remifentanil is an ultra‐short‐acting opioid, increasingly used today
in neuroanesthesia and neurointensive care. Its characteristics make remifentanil a …

IMPLICATIONS: Both fentanyl and the newer opioid remifentanil, when each is combined
with isoflurane and propofol, allowed for fast-track cardiac anesthesia. The remifentanil …

Major goals in neurosurgical anesthesia are to provide adequate tissue perfusion to the
brain (and spinal cord) so that the regional metabolic demand is met and to provide …

SummaryBackground and objective: Remifentanil has unique pharmacokinetics that might
allow faster recovery after neurosurgery. We investigated the effects of a propofol/sufentanil …

Background: Remifentanil, an ultra‐short‐acting opioid, is used as an on‐top analgesic in
head trauma patients during transient painful procedures, eg endotracheal suctioning …

Abstract Objective Transcranial Doppler ultrasound (TCD) is increasingly being used in the
pediatric intensive care unit to assess cerebral hemodynamics during critical illness …
