Management of Acute Pancreatitis

Initial Assessment and Management

All patients with severe acute pancreatitis should be managed in a high dependency unit (HDU) or intensive care unit (ICU) with full monitoring and systems support 1, 3
Basic monitoring requirements include regular hourly assessment of vital signs: pulse, blood pressure, central venous pressure, respiratory rate, oxygen saturation, urine output, and temperature 1
Continuous vital signs monitoring in high dependency care unit is needed if organ dysfunction occurs 1
Peripheral venous access, central venous line (for fluid administration and CVP monitoring), urinary catheter, and nasogastric tube should be placed in severe cases 3

Aggressive fluid resuscitation is crucial in preventing systemic complications and should be initiated promptly 2
Fluid resuscitation should aim to maintain urine output >0.5 ml/kg body weight 2
Regular monitoring of hematocrit, blood urea nitrogen, creatinine, and lactate is essential to assess adequate tissue perfusion 1

Pain control is a clinical priority in acute pancreatitis 1
No evidence supports restrictions in pain medication, though NSAIDs should be avoided in acute kidney injury 1
Dilaudid is preferred over morphine or fentanyl in non-intubated patients 1
Epidural analgesia should be considered as an alternative or adjunct to intravenous analgesia in a multimodal approach 1
Patient-controlled analgesia (PCA) should be integrated with every pain management strategy 1

Enteral nutrition is recommended over total parenteral nutrition (TPN) to prevent gut failure and infectious complications 1, 2
Both gastric and jejunal feeding can be delivered safely 1
Early enteral nutrition should be initiated, even in severe cases 3
TPN should be avoided but partial parenteral nutrition integration can be considered if enteral route is not completely tolerated 1
If ileus persists for more than five days, parenteral nutrition will be required 3

Prophylactic antibiotics are not recommended in mild cases of acute pancreatitis 4, 2
In severe acute pancreatitis with evidence of pancreatic necrosis, prophylactic antibiotics may reduce complications and deaths 2, 3
Intravenous cefuroxime is a reasonable balance between efficacy and cost for prophylaxis in severe cases 4
Antibiotics are warranted when specific infections occur (chest, urine, bile, or cannula related) 4

Urgent therapeutic ERCP should be performed in patients with acute pancreatitis of suspected or proven gallstone etiology who have severe pancreatitis, cholangitis, jaundice, or a dilated common bile duct 3, 5
The procedure is best carried out within the first 72 hours after the onset of pain 3
All patients undergoing early ERCP for severe gallstone pancreatitis require endoscopic sphincterotomy whether or not stones are found in the bile duct 3

Routine CT scanning is unnecessary in mild cases unless there are clinical signs of deterioration 4
Dynamic CT scanning should be obtained in severe cases to identify pancreatic necrosis and guide management 2
Follow-up CT is recommended only if the patient's clinical status deteriorates or fails to show continued improvement in severe cases 2

Infected necrosis is the most serious local complication with a high mortality rate (40%) 2
Surgical debridement may be necessary for infected necrosis 6
Minimally invasive approaches for debridement of infected necrosis should be considered before open surgical necrosectomy 6
Local complications such as pseudocyst and pancreatic abscess often require surgical, endoscopic, or radiological intervention 6
Each case should be managed in an individualized way by a multidisciplinary specialist pancreatic team 6

No specific pharmacological treatment except for organ support and nutrition has proven effective 1, 2
Despite extensive research, antiproteases (gabexate), antisecretory agents (octreotide), and anti-inflammatory agents have not shown benefit 2

Every hospital that receives acute admissions should have a single nominated clinical team to manage all patients with acute pancreatitis 6
Management in, or referral to, a specialist unit is necessary for patients with extensive necrotizing pancreatitis (>30% necrosis) or with other complications 6
A multidisciplinary team approach is essential for optimal management 6

Regular monitoring of vital signs and laboratory parameters is essential 1, 2
Follow-up imaging is recommended to monitor the resolution of collections in severe cases 5
Patients with mild pancreatitis require further CT only if there is a change in clinical status suggesting a new complication 2
