Diaphragmatic bulge, also known as abdominal organ protrusion and diaphragmatic bulge, belongs to the category of diaphragmatic weakness, which refers to a decrease in the intensity of diaphragmatic activity and includes diaphragmatic palsy and diaphragmatic bulge disorder. The disease is divided into congenital and acquired. For congenital diaphragm bulge, there are no effective preventive measures. In the case of acquired diaphragmatic bulge, early knowledge of the causes and prevention can effectively reduce the chances of the disease. Treatment: No or mild clinical symptoms require surgical treatment, regardless of the extent of the diaphragmatic bulge. In neonates or children with severe respiratory distress, emergency surgery is indicated. People with gastrointestinal symptoms due to gastric torsion are also indications for surgery. Diaphragmatic distension caused by phrenic nerve palsy has the potential for gradual recovery and can be temporarily observed and treated for etiology. Surgery includes removal or reduction of the weak part of the diaphragm, folding the diaphragm or performing a diagonal “ten” incision, overlapping cross sutures in the middle of the respiratory period, which is more effective. Preventive care methods: 1, sympathetic comfort patients, listen carefully to the patient’s discomfort, and give timely treatment. 2, pay attention to maintain adequate sleep, avoid overexertion, pay attention to the combination of work and rest, pay attention to the regularity of life, 3, in the diet, nutritious food is diverse, its function also varies.
