Children usually recover in about a week after an enema for intussusception. The recovery time varies due to the individual differences of the children and the different intestinal damage. Children who pay attention to diet and intestinal care after successful enema repositioning usually recover in about 7 days, and infants and young children with normal feeding, defecation and excretion are proved to have good recovery. Intussusception is one of the common acute abdominal diseases in infants and young children, and it is more common in boys with good nutritional status and obesity. It is an intestinal obstruction caused by a certain section of intestinal tube and corresponding mesentery into the adjacent intestinal tube, mainly manifested as abdominal mass, vomiting, blood in stool, paroxysmal crying or abdominal pain in infants and young children, and parents should seek medical treatment in time after discovery to avoid necrosis of the intestinal tube causing serious consequences. Air enema is one of the effective methods to solve pediatric intussusception. It is suitable for children with good general condition and less than 48 hours of illness. After successful enema, activated charcoal is taken to check the degree of intestinal patency, and usually black stools can be seen in 6~8 hours, which proves that the reset is good and the child can be discharged from the hospital. If you suspect that your child has intussusception, you should seek medical attention.
