Q

Explain pathophysiology of pancreatitis

A

Pancreatitis causes pre-mature activation of digestive enzymes. If released into circulation degrade fats and blood vessels - can lead to retroperitoneal haemorrhage.

Inflammation in pancreatitis also causes vasodilation and third space losses of fluid which may result in dehydration.

22
Q

Explain management of acute pancreatitis

A

Management is supportive, not curative. Underlying cause should be identified and addressed

23

What are 5 complications of acute pancreatitis

A
  1. DIC
  2. ARDS
  3. Pancreatic necrosis
  4. Pancreatic pesudocyts
  5. Hyperglycaemia = as pancreas damaged - islets of langerhans release less insulin
