Isotonic Saline Low Pressure Enema Test

The isotonic saline hypobaric enema test is based on the positive test of the sigmoid colon to give a normal judgment of the experimental results. Insert the intestine tube from the anus, inject the isotonic saline according to the operation method of the conventional intestine, and observe the liquid entry condition. If the liquid is filled in 500ml, it can not be refilled, or the liquid overflows from the anus is positive for the test. Liquid filling amount ≥ 1000ml is negative. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: Liquid filling amount ≥ 1000ml is negative. Positive: If the liquid is filled in 500ml, it can not be refilled, or the liquid overflows from the anus is positive for the test. A positive test indicates a sigmoid torsion. Tips: Pay attention to normal diet and rest and prevent endocrine disorders. Normal value Isotonic saline low-pressure enema test was negative. Liquid filling amount ≥ 1000ml is negative. Clinical significance A positive test indicates a sigmoid torsion. Abnormal results: sigmoid torsion has a history of chronic constipation. The main clinical manifestations of abdominal pain and progressive bloating can be divided into subacute type and acute fulminant according to the urgency of the onset. (1). Subacute type: common, accounting for about 75% to 85% of sigmoid torsion in older patients. The incidence is slow. In the past, there was a history of irregular abdominal pain and a history of disappearance of abdominal pain after defecation. The main symptoms are paroxysmal persistent pain in the lower abdomen, no defecation and venting; nausea and vomiting, but less vomiting, and vomiting in late vomiting. Progressive bloating is a feature. (2). Acute type: rare, more common in young people. The onset is urgent, and the disease develops rapidly, which is typical of low intestinal obstruction. Abdominal pain is severe, diffuse pain in the whole abdomen; vomiting occurs early and frequently due to the loss of a large amount of body fluids, and patients are prone to shock. Complications: Acute sigmoid torsion often accompanied by intestinal necrosis or perforation, clinical manifestations of acute abdomen symptoms. People to be examined: patients with suspected low colonic obstruction and sigmoid torsion. Positive results may be diseases: sigmoid colon torsion, heat secret, spleen Forbidden before examination: pay attention to normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Requirements for inspection: Actively cooperate with the doctor's request. 1. The elderly, habitual constipation, should carefully check the intestinal tube for obstruction of the feces before the test. 2. When inserting the anal canal, it should be gentle to avoid damage to the intestinal wall. Inspection process 1. The patient takes a lateral position or a knee-chest position, and the under-humer pad is a cloth or paper that absorbs water. 2. Insert the intestine tube from the anus, inject the isotonic saline according to the operation method of the conventional intestine, and observe the liquid entry condition. 3. If the liquid is still flowing through 1000ml, the test can be stopped. The result is judged: If the liquid is filled in 500ml, it can not be refilled, or the liquid overflows from the anus is positive for the test. Liquid filling amount ≥ 1000ml is negative. Not suitable for the crowd Inappropriate population: necrotic intestinal obstruction. Adverse reactions and risks Nothing.
