Results in decreased absorption of fluid and electrolytes. Mechanical Obstruction: The bowel is physically blocked by problems outside of the intestine (adhesions), in the bowel wall (Crohn’s disease), or in the intestinal lumen (tumors).  Complications of appendicitis  Hernias  Fecal impactions  Intussusception: telescoping of a segment of the intestine within itself  Volvulus (twisting of intestine) Nonmechanical: (paralytic ileus or a dynamic ileus) peristalsis is decreased or absent as a result of neuromuscular disturbance, resulting in a slowing of the movement or a backup of intestinal contents.  Complication of surgery: day 3/4, no bowel sounds  Hypokalemia Signs and Symptoms  Obstipation: severe constipation  Abdominal distention  Peristaltic waves  Borborygmic: gurgling or rumbling noise  High-pitched bowel sounds/none at all  Tachycardia  Hypokalemia Complications  Metabolic alkalosis/acidosis  Hypovolemia  Peritonitis (more so from strangulated obstruction)  Septic Shock  Increased intrabdominal pressure or ACS Interventions Non-surgical management o NG tube: at least every 4 hours, assess the patient with an NGT for proper placement, tube patency, and output (quality and quantity). Also assess for peristalsis. [Show More]
