Kidney oxygen monitoring with near-infrared light during lung transplant surgery
Association Between Renal Regional Oxygen Saturation Measured by Near-InfraRed Spectroscopy and Postoperative Renal Failure After Lung Transplantation Surgery: A Pilot Study
This project tests whether watching kidney oxygen levels with near-infrared light during lung transplant surgery can help predict which adults will develop postoperative acute kidney failure.

What this trial studies
This is a pilot observational study that records renal regional oxygen saturation using near-infrared spectroscopy (NIRS) during single or bilateral lung transplantation. Researchers will correlate intraoperative renal NIRS readings with postoperative acute kidney injury and the need for renal replacement therapy. Eligible participants are adults (≥18) undergoing lung transplant at the Marseille center, while patients with renal anatomical abnormalities, high bilirubin, preoperative ECMO, or preoperative mechanical ventilation are excluded. There is no interventional change to standard care; the goal is to see if bedside NIRS signals identify intraoperative renal hypoxia linked to later kidney failure.
Who should consider this trial
Good fit: Adults (≥18) undergoing single or bilateral lung transplantation at the Marseille center who are covered by the French social security system and do not have excluded conditions like single kidney, polycystic kidney, hyperbilirubinemia > 17mmol/l, preoperative ECMO, or preoperative mechanical ventilation.
Not a fit: Patients with renal anatomical abnormalities (single kidney, polycystic kidney), marked hyperbilirubinemia, those on preoperative ECMO or mechanical ventilation, or patients treated outside the Marseille surgical center are not eligible and are unlikely to benefit from this monitoring approach.
Why it matters
Potential benefit: If successful, this could provide a bedside way to detect renal hypoxia during surgery and prompt actions that reduce postoperative acute kidney injury and the need for dialysis.
How similar studies have performed: Near-infrared spectroscopy has shown promise for detecting renal desaturation in other surgical settings, but its use specifically during lung transplantation is novel and not yet validated.
