Whether a pediatric patient has an intestinal obstruction can usually be determined by history, symptoms, and examination. 1. Medical history: For children who have suffered from intussusception, hernia, Crohn’s disease, intestinal torsion, hernia repair or appendectomy, there is a high probability of intestinal obstruction due to intestinal blockage. 2. Symptoms: If the child has the above medical history, and accompanied by paroxysmal abdominal cramps, vomiting, no anal defecation and no bowel movement, abdominal distension and other typical symptoms, or accompanied by crying and restlessness, pallor, sweating, elevated temperature and other symptoms, it can be judged to be a pediatric intestinal obstruction. In addition, the vomit may contain bile or feces. 3. Examination: If the child’s X-ray examination shows gas in the intestinal lumen; radiographs show distended intestinal collaterals and fluid-gas planes, and routine blood tests show increased white blood cell count, hemoglobin, hematocrit, urine specific gravity, and a large number of red blood cells or positive occult blood cells are found in vomitus and feces, then it can be diagnosed as a pediatric intestinal obstruction. Pediatric intestinal obstruction requires a comprehensive diagnosis, so when pediatric intestinal obstruction is suspected, parents need to take them to the doctor immediately to prevent accidents.
