If a child has a fever and does not pass stools, first of all, let the child drink as much water as possible, not only to replenish the amount of fluids, but also to soften the stools and help reduce the fever; at the same time, cooperate with physical cooling. If the symptoms are still not relieved, give oral probiotics to improve intestinal flora and promote intestinal peristalsis, and use antipyretic drugs such as ibuprofen and acetaminophen as prescribed by the doctor. In the process of fever, most of the water in the body evaporates with sweat, while there is a loss of appetite, eating and water intake significantly reduced, resulting in a decrease in food storage in the digestive system of children, coupled with the evaporation of most of the water, resulting in children’s stools are relatively dry, thus causing children with fever do not stool. 1, diet: let children eat a light diet, drink more water, eat more food rich in Fiber vegetables, such as cabbage, celery, leek, broccoli, etc., eat more fruits with laxative effect, such as bananas, dragon fruit; 2, medication: If the fever cannot be effectively relieved by physical cooling, you can use antipyretic drugs, such as ibuprofen, acetaminophen, under the guidance of a doctor. At the same time, give children oral intestinal probiotics to improve intestinal flora, promote intestinal peristalsis and help stool discharge. Probiotics can be taken orally as Bacillus subtilis diphtheriae pellets or Saccharomyces boulardii dispersion. If after 3-5 days, the child is still unable to pass stools on his own, he can temporarily use a special open-loop for infants for laxative treatment. Most children can gradually pass stools smoothly after diet adjustment and oral probiotics. Some children who do not pass stool with fever need to be investigated for surgical emergencies, for example, if the child does not pass stool with fever, is accompanied by non-exhaustion, has obvious nausea, vomiting, abdominal pain, etc., and needs to be investigated for acute appendicitis or intussusception. Parents should take their children to the hospital for routine blood tests and abdominal ultrasound, and if necessary, surgical treatment should be given in a timely manner.
