Peritonitis is an acute, life-threatening inflammation of the peritoneum usually caused by bacterial contamination from gastrointestinal perforation, infection, or intra-abdominal pathology. It leads to severe abdominal pain, fluid shifts into the peritoneal cavity, and systemic inflammatory response. Management requires rapid stabilization, infection control, bowel rest, and supportive care. Collaborative interventions focus on preventing sepsis, maintaining fluid balance, and reducing further peritoneal irritation. A. Intravenous fluids are essential in managing Peritonitis because significant third spacing of fluids into the abdominal cavity can lead to hypovolemia and shock. IV fluids help maintain circulatory volume, support blood pressure, and improve tissue perfusion. Early aggressive fluid resuscitation is a key component of stabilizing the patient. B. Supine positioning is not typically recommended because it can increase abdominal pressure and discomfort in patients with Peritonitis. Patients are often positioned in semi-Fowler’s position to promote lung expansion and reduce pressure on the diaphragm. Supine positioning may worsen pain and compromise respiratory function. C. A nasogastric tube (NGT) to suction is used to decompress the gastrointestinal tract in Peritonitis. This helps reduce gastric distention, prevent vomiting, and minimize further leakage of gastrointestinal contents into the peritoneal cavity. It also decreases abdominal pressure and supports bowel rest. D. NPO status is essential to rest the gastrointestinal tract and prevent further contamination in Peritonitis. Withholding oral intake reduces bowel activity and limits worsening of infection or leakage in cases of perforation. This is a standard initial management step until surgical or medical stabilization occurs. E. IV analgesic medications are important because Peritonitis causes severe abdominal pain due to intense inflammation of the peritoneal lining. IV administration is preferred because oral medications are contraindicated in NPO status and absorption may be unreliable. Pain control also helps reduce stress response and improve patient comfort. F. Oral antibiotics are not appropriate in acute peritonitis because absorption may be impaired and the condition often requires rapid systemic treatment. In Peritonitis, antibiotics are administered intravenously to ensure immediate and effective therapeutic levels. Oral therapy would delay treatment and is not suitable for acute or severe infection.
