The baby can be initially diagnosed with intussusception through clinical symptoms of abdominal pain and abdominal mass, and the diagnosis needs to be confirmed by ultrasound and other relevant examinations. It is common for babies to have sudden onset of severe and regular paroxysmal colic that lasts for 15-20 minutes. However, as the baby is unable to describe the symptoms on his/her own, the abdominal pain may be accompanied by paroxysmal crying and recurrent episodes. A sausage-like mass may be palpable in the baby’s abdomen. Some babies may have symptoms such as fidgeting, pallor, refusal to eat, vomiting, high fever and lethargy, which should be considered as intussusception. If the baby has the above symptoms, parents should bring the baby to the whole hospital for ultrasound, air enema, CT examination, etc., so as to clarify the cause of the disease. Parents should not give medication to their babies before the diagnosis is confirmed, so as not to cover up the symptoms. Once the diagnosis of intussusception is confirmed after relevant examinations, parents need to actively cooperate with doctors to take relevant treatment measures. In daily life, parents should take reasonable diet, do not let the baby overeat, and pay attention to the warmth of the abdomen.
