Objective Nociceptive Assessment in Ventilated ICU Patients: A Feasibility Study Using Pupillometry and the Nociceptive Flexion Reflex Davina Wildemeersch1, Jens Gios2, Philippe G. Jorens3, Guy H. Hans2 1Multidisciplinary Pain Center, Anesthesiology and Critical Care Medicine, Antwerp University Hospital (UZA), University of Antwerp (UA), 2Multidisciplinary Pain Center (PCT), Antwerp University Hospital (UZA), 3Critical Care Medicine, Antwerp University Hospital (UZA), University of Antwerp (UA) Pain assessment in anesthetized patients who cannot communicate with the outside world in any way remains challenging despite the development of innovative objective pain evaluation tools. In this project, the pupillary dilation reflex and the nociception flexion reflex are assessed in critically ill, mechanically ventilated adult patients.
In Vitro Recording of Mesenteric Afferent Nerve Activity in Mouse Jejunal and Colonic Segments Sara Nullens1, Annemie Deiteren2, Wen Jiang3, Christopher Keating4, Hannah Ceuleers1, Sven Francque5, David Grundy3, Joris G.

Gastrointestinal afferent nerve activity can be assessed by mounting isolated intestinal segments with attached afferent nerves into an organ bath, isolating the nerve, and assessing basal as well as stimulated activity.
Chronic Constriction Injury of the Rat's Infraorbital Nerve (IoN-CCI) to Study Trigeminal Neuropathic Pain Kristof Deseure1, Guy H. Hans2 1Translational Neurosciences, University of Antwerp, 2Multidisciplinary Pain Center, Antwerp University Hospital This manuscript describes a rodent model to study trigeminal neuropathic pain. The methods described include surgical procedures to perform a chronic constriction injury of the rat’s infraorbital nerve and the post-surgical behavioral tests to measure the changes in spontaneous and evoked behavior that are indicative of persistent pain and allodynia.
