Early Co-Administration of 30 mL/kg Crystalloid Fluid and Norepinephrine for Preventing Acute Kidney Injury in Septic Shock: A Pretest-Posttest Clinical Study

This study is a pretest-posttest interventional clinical study designed to evaluate the effectiveness of early co-administration of crystalloid fluid resuscitation and norepinephrine in patients with septic shock. Septic shock is characterized by persistent hypotension requiring vasopressor therapy despite adequate fluid resuscitation and is associated with a high risk of acute kidney injury.

Eligible participants are adult patients diagnosed with septic shock who meet the study inclusion criteria. All participants will receive crystalloid fluid resuscitation at a dose of 30 mL/kg body weight, followed by early initiation of norepinephrine infusion at an initial dose of approximately 0.05 µg/kg/min, titrated according to hemodynamic response and clinical judgment.

Hemodynamic parameters, including mean arterial pressure, heart rate, oxygen saturation, urine output, and central venous pressure (when available), will be measured before and after the intervention. Renal function indicators will be monitored to assess the occurrence of early acute kidney injury.

The primary objective of this study is to evaluate the effect of early combined fluid resuscitation and norepinephrine administration on the prevention of acute kidney injury. Secondary objectives include assessment of changes in hemodynamic stability following the intervention. The results of this study are expected to contribute to evidence-based management strategies for septic shock in resource-limited clinical settings.
