From the Guidelines

Patients with severe acute pancreatitis, particularly those with persistent organ failure, should be admitted to an intensive care unit (ICU) for close monitoring and management. Pancreatitis symptoms include severe upper abdominal pain that may radiate to the back, nausea, vomiting, fever, and abdominal tenderness 1. Diagnostic workup involves blood tests (amylase, lipase, liver enzymes, triglycerides), imaging studies (abdominal ultrasound, CT scan, or MRI), and sometimes ERCP for gallstone-related cases. Treatment focuses on supportive care with IV fluids, pain management with medications like morphine or hydromorphone, and bowel rest (NPO status) 1.

Some key points to consider in the management of pancreatitis include:

  • Early aggressive fluid resuscitation with lactated Ringer's solution at 5-10 mL/kg/hr is crucial in the first 24-48 hours to prevent complications 1
  • Patients with organ failures should be admitted to an intensive care unit whenever possible 1
  • The underlying cause must be addressed, such as gallstone removal, alcohol cessation, or medication adjustment
  • Complications like pseudocysts, necrosis, or infection may require additional interventions including antibiotics (such as imipenem 500mg IV q6h), percutaneous drainage, or surgery

The Revised Atlanta Classification and Determinant-based Classification of Acute Pancreatitis Severity are similar in establishing the diagnosis and severity of acute pancreatitis, and both are useful in guiding management decisions 1. Patients who have persistent organ failure with infected necrosis have the highest risk of death, and should be managed aggressively in an ICU setting 1.

In terms of specific treatment, some options include:

  • IV fluids and pain management for supportive care
  • Bowel rest (NPO status) to reduce pancreatic stimulation
  • Antibiotics (such as imipenem 500mg IV q6h) for infected necrosis or other complications
  • Percutaneous drainage or surgery for complications like pseudocysts or necrosis
  • Early aggressive fluid resuscitation with lactated Ringer's solution at 5-10 mL/kg/hr to prevent complications 1

From the Research

Symptoms of Pancreatitis

  • Upper abdominal pain is a common symptom of acute pancreatitis 2, 3, 4
  • The diagnosis of acute pancreatitis is usually based on the presence of abdominal pain and elevated levels of serum amylase and/or lipase 2
  • Other symptoms may include nausea, vomiting, and fever 3, 4

Diagnostic Workup

  • Serum amylase and lipase levels are used to diagnose acute pancreatitis, but they are not specific for pancreatitis 2, 5
  • Serum lipase levels are more sensitive and specific than amylase, but still not sufficient to diagnose acute pancreatitis in patients with abdominal pain 2, 5
  • Radiological evidence, such as cross-sectional imaging, is important for a more accurate diagnosis of acute pancreatitis 4, 5
  • Other tests, such as serum triglycerides, full blood count, renal and liver function tests, glucose, calcium, and transabdominal ultrasound, may also be indicated 4

Treatment

  • Initial priorities are intravenous fluid resuscitation, analgesia, and enteral nutrition 3, 4
  • Critical care and organ support, parenteral nutrition, antibiotics, pancreatic exocrine and endocrine replacement therapy may be necessary in some cases 4
  • Patients with local complications should be referred to specialist tertiary centres to guide further management, which may include drainage and/or necrosectomy 4
  • Cholecystectomy during the same admission of biliary pancreatitis should be performed to prevent future acute pancreatitis episodes 3

Need for ICU Admission

  • Patients with severe acute pancreatitis, persistent organ failure, or significant morbidity may require admission to the intensive care unit (ICU) 3, 6, 4
  • Early management of patients with acute pancreatitis is crucial to prevent severe disease, complications, and death, and ICU admission may be necessary in some cases 6
