>> Why objectify analgesia <<

Analgesia is one of the three fundamental pillars in the management of anaesthetised or sedated patients.

Inadequate analgesia can lead to post-operative complications, excessive nociception and agitation.

Excessive analgesia can lead to undesirable effects such as hypotension, bradycardia, prolonged recovery times, nausea and vomiting, and morphine-related hyperalgesia.

It is therefore important to be able to assess the level of analgesia eobjectively, tailored to each individual patient.

>> How to Measure Analgesia <<

The AlgiScan delivers the Pupillary Pain Index (PPI), a score that reflects the patients’ level of analgesia.

The pupil is the most sensitive marker of nociception and has the particularity of being specific to nociception in case of unconscious patients. The PPI is calculated from pupillary dilation during increasing infra-nociceptive stimulation.

A higher PPI score (close to 9), indicates higher sensitivity to nociception and lower analgesia whereas a PPI score close to 1 indicates high analgesia.

>> PPI score and AlgiScan <<

AlgiScan is a simple and non-invasive tool that enables anaesthesia and intensive care teams to optimise the management of nociception quickly and effectively.

AlgiScan’s PPI score can be used to anticipate the patient’s needs and make preventive therapeutic adjustments before any nociceptive stimulus.

By targeting a PPI score, anaesthesia and critical care teams can obtain an objective, personalised and predictive interpretation of their analgesia strategy implemented.

TESTIMONIALS

During our daily practice, we often come across paediatric patients who wake up agitated after anaesthesia, even when they are supposed to have received adequate intraoperative or postoperative analgesia. What attracted me to AlgiScan is its simplicity, portability (it can easily fit in one’s pocket), and user-friendly interface.

With AlgiScan, we now have the ability to predict the depth of analgesia in paediatric patients before extubating them.

I observed that in neurosurgical intensive care, patients with brain damage had very low PPI scores. This means that they were receiving an excessive amount of morphinics in relation to their actual analgesic needs. The integration of the PPI would allow for better adjustment of morphine doses, in order to ensure optimal analgesia without excess. Measurement of PPI can be a method to objectify nociception. The PPI makes it possible to link a state of agitation to a real lack of analgesia.

” What is not defined cannot be measured. What is not measured, cannot be improved ” (Peter Drucker / William Thomson). It is crucial to monitor and measure the intensity of nociception to quantify and treat it effectively. By controlling the magnitude of nociception, we can prevent it and reduce the need for opioids during or after surgery. The AlgiScan has been proven to be an effective monitor that fulfils these goals in clinical practice.

I can see that AlgiScan provides a unique feature of predicting the response to a nociceptive stimulus. This helps in adjusting morphinics doses before and during surgery or preparing for postoperative analgesia, based on an objective assessment of the patient’s response to infra-nociceptive stimulation. The most valuable aspect about using this monitor is the ability of the PPI mode to predict the reaction to a nociceptive stimulus.

"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.

"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.
