After the reset of pediatric intussusception by air enema, the first thing that needs to be done is to review the abdominal ultrasound to make sure whether the reset is complete or not. In addition, you need to check the stool, some children will have bloody stools, or even a longer period of time, so you need to closely observe whether there is any aggravation of bloody stools or even infection. After the enema needs to be observed for 48h, if the child cries and vomits again, it is necessary to repeat the ultrasound as soon as possible to determine whether the intussusception is repeated. In terms of diet, it is recommended to eat a light diet after the enema is reset, and a small amount of liquid diet can be started after 6h, and if there is no obvious vomiting and abdominal pain, a semi-liquid diet can be started. During this period, we need to closely observe the child’s mental state, see whether the child has vomiting, abdominal distension, and pay attention to the child’s stool, if the stool color gradually turns yellow and the mental state is good, it means that the situation is recovering well and basically cured.
