  "overview": [
    "Peritonitis is inflammation of the peritoneum, usually from bacterial contamination after perforation of a hollow organ — a ruptured appendix, perforated ulcer, diverticulum or bowel — or from peritoneal dialysis catheter contamination. It is a surgical emergency: fluid and bacteria pour into the peritoneal cavity, huge volumes third-space out of circulation, and untreated the patient progresses to septic shock and multi-organ failure.",
    "The classic presentation is severe, constant abdominal pain with a board-like rigid abdomen, rebound tenderness, absent bowel sounds, fever, tachycardia and a patient who lies still with knees flexed because any movement hurts. Paralytic ileus follows quickly, adding distention and vomiting.",
    "Management is fluid resuscitation, broad-spectrum antibiotics, NPO status with nasogastric decompression, pain control and source control in the operating room. Nursing care centers on early recognition, hemodynamic monitoring, and vigilance for the deterioration into sepsis."
