September 20, 2017 – Two New Clinical Poster Presentations Focusing on Pupillometry
OPATIJA, CROATIA – Two clinical poster presentations focusing on pupillometry were presented at the 12th Annual Congress of the World Federation of Neuroscience Nurses held Sept. 17-21, 2017 in Croatia.
The first poster, “Is Variance in Pupillary Function Associated With Discharge Outcomes?”, authored by T Tien Ho, S Stutzman, F Atem, B Carlisle, V Aiyagari, D Olson from the Department of Neurology and Neurotherapeutics and Neurological Surgery, UT Southwestern Medical Center, explores the association between changes in the Neurological Pupil index™ (NPi®) and hospital discharge outcomes measured by the Modified Rankin Scale (mRS). Data for the analysis was obtained from 716 patients with a SAH or ICH from the END-PANIC registry, a nursing-led multicenter prospective pupillometer study. The authors conclude that both NPi at baseline and change in NPi over time are associated with discharge outcomes in SAH and ICH patients. Lower NPi score at baseline is associated with worse (higher) mRS at discharge and that decreasing NPi values during the course of stay are associated with worse mRS at discharge.

In the second poster, “Normative Data of Pupillary Reading in Neurocritical Care Patients”, authored by D Olson, V Aiyagari, B Carlisle, T Tien Ho and S Stutzman from UT Southwestern Medical Center, a large sample of patient pupil data was collected as a part of the study, characterizing pupil observations and physiological data to report central tendencies and findings. Data was collected from 987 neurocritical care patients over a span of 24 months.
The poster provides a foundation for a better understanding of pupil norms when using a pupillometer (NeurOptics® NPi®-200 Pupillometer) and generates data that can assist clinicians in better understanding Neurological Pupil index (NPI) values. The authors conclude knowing the normal values for pupil size and reactivity (NPi) will assist the critical care nurse in determining which assessment findings are not within normal limits and thus require intervention or additional assessment.
