Effect of Preoperative Hemoglobin Levels on Acute Kidney Injury After Emergency Non-Cardiac Surgery A Prospective Observational Study

What this Trial Is About

Researchers are studying how hemoglobin levels before emergency surgery affect the chance of developing acute kidney injury AKI afterward. While anemia is linked to serious organ problems like coronary artery disease, the impact of blood transfusions or other ways to raise hemoglobin on patient outcomes remains unclear. This study aims to clarify the relationship between preoperative hemoglobin and AKI after adjusting for known risk factors. This prospective observational study involves patients having emergency non-cardiac surgery. Participants will be divided into two groups those who develop postoperative AKI and those who do not. Researchers will assess kidney injury using established criteria based on blood and urine tests. Data collected will include patient demographics, blood counts, biochemistry, fluid and blood replacement, surgery details, and the severity of any kidney injury. Participants will be monitored closely during and after surgery to record kidney function changes and hospital stay length. The primary outcome is the occurrence of acute kidney injury within 72 hours after surgery. Secondary outcomes include the total days spent in the hospital within one month. This careful observation will help understand how pre-surgery hemoglobin levels relate to kidney health after emergency operations.
