The baby has had diarrhea for over a week, and hematochezia appeared after the stool became loose. After receiving needle treatment, the stool still did not form properly, with white blood cells ranging from 1 to 2. Oral medication had been administered previously, which was then switched to intravenous treatment. Two days later, the hematochezia disappeared, and the white blood cell count decreased, but the stool still did not form properly. The doctor advised continuing the intravenous treatment until the stool becomes normal. Seeking treatment advice.
