Paralytic ileus is a disorder characterized by abnormal intestinal muscle contractions, leading to the inability of intestinal contents to pass out of the body. It is typically a temporary condition and often occurs after abdominal surgery. It can also be triggered by severe abdominal injury, peritonitis (inflammation of the abdominal lining), acute pancreatitis (inflammation of the pancreas), significant disruptions in blood chemistry (like diabetic ketoacidosis), or interference with the blood or nerve supply to the intestine. Symptoms include abdominal swelling, vomiting, and the inability to pass feces.
The treatment for this condition involves resting the intestine. To achieve this, a tube is inserted through the nose or mouth and into the stomach or intestine to drain accumulated fluids and keep the stomach empty. Body fluid levels are sustained through intravenous infusion (drip).
