Intra-Abdominal Pressure Changes During Continuous Renal Replacement Therapy in Critically Ill Patients

This prospective observational study will evaluate changes in intra-abdominal pressure in critically ill adult patients receiving continuous renal replacement therapy in the intensive care unit. Intra-abdominal pressure will be measured through the urinary bladder at predefined time points during therapy. The study will also assess the relationship between intra-abdominal pressure changes and clinical variables, including fluid balance, hemodynamic parameters, vasopressor requirement, urine output, severity scores, duration of renal replacement therapy, intensive care unit and hospital length of stay, and 30-day survival. No additional treatment or therapeutic intervention will be administered for research purposes.
