Association of Intraoperative Renal Regional Oxygen Saturation and Acute Kidney Injury

Liver Transplant; Complications Clinical Trial

Official title:
Association of Intraoperative Renal Regional Oxygen Saturation and Acute Kidney Injury After Living Donor Liver Transplantation

Clinical Trial Summary

This study is a prospective observational study of a single cohort of the patients who will undergo a scheduled living donor liver transplantation. The investigators attempt to evaluate the association of intraoperative renal regional oxygen saturation and acute kidney injury in patients undergoing living donor liver transplantation. Near-infrared spectroscopy sensor will be attached to the skin near bilateral kidney areas in all patients and renal regional oxygen saturation will be monitored during the operation. Renal regional oxygen saturation (rSO2) of the patients who developed acute kidney injury postoperatively will be compared with rSO2 of the patients who did not.

Clinical Trial Description

Acute kidney injury is a frequent complication after liver transplantation, which is related to poor prognosis and longer hospital stay. There is no sensitive or specific marker for predicting postoperative acute kidney injury, although studies of the biomarkers have shown promising results. Near-infrared spectroscopy is a non-invasive and real-time monitoring device for regional oxygen saturation measurement. Previous studies revealed that it could be applied to the skin near the kidney and be used to monitor renal regional oxygen saturation. Therefore, in this study, the investigators will apply near-infrared spectroscopy around kidney area to measure real-time renal regional oxygen saturation during liver transplantation surgery and investigate the association between the intraoperative renal regional oxygen saturation and the development of post-transplant acute kidney injury. ;
