Key Components in the Management of Acute Pancreatitis

The management of acute pancreatitis requires a stratified approach based on disease severity, with aggressive fluid resuscitation, early enteral nutrition, appropriate antibiotic use, and multidisciplinary care as the cornerstones of treatment. 1, 2

Initial Assessment and Stratification

• Acute pancreatitis should be classified as mild (80% of cases, <5% mortality) or severe (20% of cases, 95% of deaths) to guide appropriate management 3
• Severity assessment should be performed using validated scoring systems to identify patients at risk for complications 2
• The etiology of acute pancreatitis should be determined in 75-80% of cases, with no more than 20-25% classified as "idiopathic" 3

Fluid Resuscitation

• Aggressive fluid resuscitation is crucial in preventing systemic complications and should be initiated promptly in all patients 1, 4
• Lactated Ringer's solution is preferred over normal saline for fluid resuscitation 2, 5
• Fluid resuscitation should aim to maintain urine output >0.5 ml/kg body weight 1, 2
• Avoid hydroxyethyl starch (HES) fluids as they increase the risk of multiple organ failure 2

Monitoring Requirements

• For mild pancreatitis: Basic monitoring of temperature, pulse, blood pressure, and urine output on a general ward 3
• For severe pancreatitis: Management in ICU/HDU with peripheral venous access, central venous line, urinary catheter, and nasogastric tube 3, 1
• Regular arterial blood gas analysis is essential in severe cases to detect hypoxia and acidosis 3
• Hourly monitoring of pulse, blood pressure, CVP, respiratory rate, oxygen saturation, urine output, and temperature in severe cases 3, 1

Nutritional Support

• Early enteral nutrition (within 24 hours) is strongly recommended over parenteral nutrition to prevent gut failure and infectious complications 1, 2
• Both nasogastric and nasojejunal feeding routes are acceptable for enteral nutrition 1, 2
• Oral feeding can be initiated in mild cases as soon as pain and nausea subside 2
• Parenteral nutrition should only be considered if enteral feeding is not tolerated after 5 days 1, 2

Pain Management

• Pain control is a clinical priority in acute pancreatitis 1, 2
• Dilaudid is preferred over morphine or fentanyl in non-intubated patients 1, 2
• Patient-controlled analgesia (PCA) should be integrated with pain management strategies 1, 2
• Epidural analgesia should be considered as an alternative or adjunct to intravenous analgesia 1, 2

Antibiotic Therapy

• Prophylactic antibiotics are NOT recommended in mild acute pancreatitis 3, 1
• In severe acute pancreatitis with pancreatic necrosis, prophylactic antibiotics may reduce complications 3, 1
• Intravenous cefuroxime is a reasonable choice for prophylaxis in severe cases when indicated 3, 2
• Antibiotics are warranted when specific infections occur (respiratory, urinary tract, biliary, or catheter-related) 3, 1

Management of Biliary Causes

• Urgent ERCP (within 72 hours) is indicated in patients with acute pancreatitis and concomitant cholangitis, jaundice, or dilated common bile duct 1, 2
• Failure of the patient's condition to improve within 48 hours despite intensive resuscitation is an indication for urgent ERCP in gallstone pancreatitis 3
• Cholecystectomy should be performed during the initial admission for mild biliary pancreatitis 2
• For severe biliary pancreatitis, cholecystectomy should be delayed until resolution of inflammation and systemic disturbance 2

Imaging

• Routine CT scanning is unnecessary in mild cases unless there are clinical signs of deterioration 3, 1
• Dynamic CT scanning should be obtained within 3-10 days of admission in severe cases to identify pancreatic necrosis 3, 1
• Follow-up CT is recommended only if the patient's clinical status deteriorates or fails to improve 1, 2

Management of Complications

• Infected necrosis is the most serious local complication with high mortality (40%) 1, 2
• Patients with infected necrosis require intervention to debride necrotic material 2
• Minimally invasive approaches should be considered before open surgical necrosectomy 1, 2
• Local complications such as pseudocyst and pancreatic abscess often require surgical, endoscopic, or radiological intervention 1

Specialist Care

• All cases of severe acute pancreatitis should be managed in an HDU or ICU setting with full monitoring and systems support 3, 1
• Every hospital should have a single nominated clinical team to manage all patients with acute pancreatitis 1, 2
• Management in, or referral to, a specialist unit is necessary for patients with extensive necrotizing pancreatitis or with other complications 1

Common Pitfalls to Avoid

• Overaggressive fluid resuscitation may be harmful in certain patients with severe disease 5
• Routine use of prophylactic antibiotics in mild cases provides no benefit 3, 1
• Delaying enteral nutrition unnecessarily increases risk of complications 1, 2
• Failing to identify and treat biliary causes promptly can worsen outcomes 3, 2
• Specific pharmacological treatments (aprotonin, glucagon, somatostatin, fresh frozen plasma) have not proven beneficial and should not be used 3
