Analgesia – AlgiScan

Intensive care / Operating theater

The AlgiScan uses pupillometry technology to objectively measure the patient’s level of analgesia.

This technic is well published and documented. It offers robust and relevant results for the evaluation of the sensibility level to nociception and the prediction of haemodynamic reactions to nociceptive stimuli. The fast and non invasive measurements bring unequalled precision while safe for the eye.

The integrated lighting system offers the possibility to do the routine check of the pupil size and reactivity with reliable measurements.

With its small size it is possible to position the AlgiScan on all types of morphology and to easily access the pupil for measurements in ICU and Operating Theaters. The AlgiScan is a portable and intuitive device for the assessment of patient analgesia in all situations.

Its reusable and autoclavable eyecup eliminates any extra cost in use. Its design and the materials used provide ergonomics and absolute comfort for the patient while eliminating the influence of ambient lights on measurement results.

The STA-W2 charging station makes it easy to recharge the AlgiScan at any time.

"Pupillary reflex dilation in response to incremental nociceptive stimuli in patients receiving intravenous ketamine."

Sabourdin N, Giral T, Wolk R, Louvet N, Constant I.


Pupillometry is a non-invasive monitoring technique, which allows dynamic pupillary diameter measurement by an infrared camera. Pupillary diameter increases in response to nociceptive stimuli. In patients anesthetized with propofol or volatile agents, the magnitude of this pupillary dilation is related to the intensity of the stimulus. Pupillary response to nociceptive stimuli has never been studied under ketamine anesthesia. Our objective was to describe pupillary reflex dilation after calibrated tetanic stimulations in patients receiving intravenous ketamine. After written consent, 24 patients of our pediatric burn care unit were included.

"Pupillary reflex measurement predicts insufficient analgesia before endotracheal suctioning in critically ill patients"

Paulus J, Roquilly A, Beloeil H, Théraud J, Asehnoune K, Lejus C.


This study aimed to evaluate the pupillary dilatation reflex (PDR) during a tetanic stimulation to predict insufficient analgesia before nociceptive stimulation in the intensive care unit (ICU).

"Intraoperative monitoring of analgesia using nociceptive reflexes correlates with delayed extubation and immediate postoperative pain: A prospective observational study."

Jakuscheit A, Weth J, Lichtner G, Jurth C, Rehberg B, von Dincklage F.


Immediate postoperative pain could be prevented by the administration of long-lasting analgesics before the end of the anaesthesia. However, to prevent over or underdosing of analgesics under anaesthesia, tools are required to estimate the analgesia-nociception balance.
