Effects of hemoglobin levels on kidney injury after emergency surgery

The Association Between Preoperative Hemoglobin and Acute Kidney Injury in Emergency Surgery: A Prospective Observational Study

Observational Samsun University · NCT06857630

This study is testing if having higher hemoglobin levels before emergency surgery can help prevent kidney injury in patients after the operation.

What this trial studies

This observational study aims to evaluate how preoperative hemoglobin levels affect the development of acute kidney injury (AKI) in patients undergoing emergency non-cardiac surgery. Patients will be categorized into two groups based on whether they develop AKI postoperatively. The study will collect demographic data, blood counts, biochemistry, hemodynamic variables, and surgical characteristics to analyze the relationship between hemoglobin levels and AKI outcomes. The findings could clarify the role of hemoglobin optimization in preventing kidney complications in critically ill surgical patients.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for emergency non-cardiac surgery.

Not a fit: Patients with known renal failure or those requiring reoperation within 48 hours post-surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for managing hemoglobin levels in emergency surgery patients, potentially reducing the incidence of acute kidney injury.

How similar studies have performed: While some studies have explored the relationship between hemoglobin levels and AKI, this study's specific focus on emergency surgery is relatively novel.
