Hernia incarceration manifests as a sudden increase in the size of the hernia mass, accompanied by significant pain. The hernia mass cannot be retracted by pushing with the hand. To determine whether a child’s hernia is incarcerated or not, you can determine whether a child’s hernia is incarcerated or not through symptoms and related examinations. 1. Symptoms: When a child has a hernia, if it is not incarcerated, the lump can disappear after lying down and reducing abdominal pressure, or an experienced parent can push the lump back into the abdominal cavity. If the hand gently push can not be returned, and the child cried a lot, and vomiting and other symptoms, then it may be incarcerated. 2. Related examination: when the child hernia can improve the abdominal ultrasound examination, in order to determine the existence of hernia incarcerated. Once incarcerated should be timely surgical treatment to avoid delay or cause intestinal necrosis. If a child has a hernia, it is recommended that he or she be seen by a specialist who can evaluate the hernia and give him or her targeted treatment.
