To evaluate the association between automated pupillometry parameters and delirium in surgical patients admitted to intensive care units (ICU) with high risk of pain.
Key Findings:
Among 49 patients, 12% had positive CAM-ICU assessments.
Average pupillary latency (LAT avg) was significantly shorter in patients with delirium (p = 0.01).
LAT avg was independently associated with delirium after adjusting for sedation depth, level of consciousness, and pain intensity (OR 1.55 per 0.01; 95% CI 1.13–2.13; p = 0.007).
Interpretation:
Remove unsupported implications about the usefulness of automated pupillometry.
Limitations:
The study was limited to surgical ICU patients, which may affect generalizability.
Potential confounding factors related to pain intensity were not fully explored.
Conclusion:
Revise to reflect only the findings without suggesting it may serve as a tool.
