Investigating breath compounds and biomarkers to understand postoperative delirium in older adults

Exhaled volatile organic compounds, phospho-tau and postoperative delirium

NIH-funded research University of Virginia · NIH-10732133

This study is looking at how we can better predict confusion after surgery in older adults, especially those with Alzheimer's or similar conditions, by checking their breath and blood samples, and it’s designed for patients aged 65 and older who are having spine surgery.

What this research studies

This research focuses on understanding postoperative delirium (POD) in elderly patients, particularly those with Alzheimer's disease or related dementias. It aims to identify unique patterns of volatile organic compounds (VOCs) in the breath of patients who experience POD compared to those who do not. By analyzing these breath samples alongside blood biomarkers like phospho-tau, the study seeks to develop a non-invasive method for predicting POD, which can be performed at the bedside. The research will involve 150 patients aged 65 and older undergoing spine surgery, with the goal of improving early detection and management of POD.

Who could benefit from this research

Good fit: Ideal candidates for this research are elderly patients aged 65 and older who are scheduled for spine surgery.

Not a fit: Patients who are younger than 65 or those not undergoing spine surgery may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to a non-invasive method for early detection of postoperative delirium, improving outcomes for elderly patients.

How similar studies have performed: Previous research has shown promise in using breath analysis for various medical conditions, suggesting potential for success in this novel approach.
