The child's position is lying on his back with his head tilted to one side, legs extended. The catheter is placed in the anus by the nurse and the catheter is connected to a defibrillator with a pressure control valve. The doctor inserts air into the colon through a catheter. The radiologist will take pictures when seeing the image of the intussusception, the doctor continues to pump air into the colon, the intussusception gradually moves until the gas suddenly rushes into the small intestine, when the intussusception is removed. The radiologist takes a second film after the cage block is removed. At this time, the nurse will remove the catheter from the machine to let the air in the intestines escape almost completely and then remove the catheter from the anus. After successful intussusception, the child usually has no pain, sleeps peacefully, bloody diarrhea may still be present but will gradually decrease, the stool turns yellow. The stool may be loose because when removing the intussusception, more water is absorbed into the intestinal lumen. Depending on the child's condition, the doctor will prescribe intravenous fluids to relieve anesthesia (if there is a pre-anesthesia injection), water and electrolyte replacement. Children need to be monitored for recovery for about 12-24 hours and then discharged from the hospital. The advantage of the air intubation method is that the process is quite fast and effective after about 5-10 minutes. But in some cases, the child arrives late, has a lot of bloody diarrhea, the tight intussusception may not be removed immediately, the doctor will prescribe fluid and electrolyte replacement, antibiotic injection and removal of the cage after about 1 hour. .
