Portable infrared pupillometers provide an objective measure of pupil size and pupillary
reflexes, which for most clinicians was previously only a visual impression. But despite the …

Analgesia (pain relief) amnesia (loss of memory) and immobilisation are the three major
components of anaesthesia. The perception of pain, and therefore, the need for analgesia, is …

Background The evaluation of pain intensity during the immediate postoperative period is a
key factor for pain management. However, this evaluation may be difficult in some …

Quantitative pupillometry provides a noninvasive and objective assessment within the
neurological examination. This review details the physiology of the pupillary light response …

La monitorización de la profundidad de la anestesia es un aspecto particularmente
importante del procedimiento. Permite decidir el tipo y dosis de anestésico administrado de …

Introduction This study aimed to evaluate the pupillary dilatation reflex (PDR) during a
tetanic stimulation to predict insufficient analgesia before nociceptive stimulation in the …

Purpose: Pupillometry is a technique for objective quantification of nociception that takes
into account the central processing of noxious stimuli and its sympathetic response. This …

OBJECTIVE: This study tested the hypothesis that increased activity in the pupilloconstrictor
nucleus by the addition of ambient light and by the administration of fentanyl, sufficient to …

Anesthesia results from several inhibitor processes, which interact to lead to loss of
consciousness, amnesia, immobility, and analgesia. The anesthetic agents act on the whole …

Objective A systematic literature search has been performed to identify potential
confounders for outcome prediction using pupillary light reflex in adult critically ill patients …
