Dextran 40 Plus Ringer's Lactate Vs. Ringer's Lactate Alone for Fluid Resuscitation in Acute Pancreatitis

This clinical trial aims to learn if a combination of Dextran 40 and Ringer's lactate solution can improve fluid resuscitation in mild and moderate acute pancreatitis (AP) and prevent complications. The main questions it aims to answer are: Does early fluid resuscitation with Dextran 40 plus Ringer's lactate improve patient outcomes compared to Ringer's alone? Does this treatment reduce inflammation, organ failure, and the need for intensive care unit (ICU) admission? Researchers will compare Dextran 40 plus Ringer's lactate to Ringer's alone to see if the combination therapy is more effective in reducing disease severity and complications. Participants will: Receive either Dextran 40 plus Ringer's lactate (1:3 ratio) or Ringer's lactate alone. Have blood tests every 24 hours to measure inflammation and organ function. Be monitored for changes in disease severity, need for ICU admiss
