It helps replace lost fluids and electrolytes, making it an ideal choice for resuscitation in such scenarios. Normal saline is commonly used for volume resuscitation but may not be the best choice for these specific conditions. Dextrose is a source of glucose and is not typically used as the primary fluid for GIT losses and burns. Blood transfusion is indicated for specific situations like severe hemorrhage or anemia but is not the primary fluid for GIT losses and burns.
