Acute Pancreatitis Flashcards
What is it?
A disorder of the exocrine pancreas, and is associated with acinar cell injury with local and systemic inflammatory responses
Causes of pancreatitis + mmemonic?
GET SMASHED
Gallstones Ethanol Trauma Steroids Mumps/HIV/Coxsackie Autoimmune Scorpion Venom Hypercalcaemia/hyperLIPIDAEMIA/hypothermia ERCP Drugs (e.g. sodium valproate, steroids, thiazides and azathioprine)
Most common cause in males/females?
Most common cause in:
Males = alcohol Females = gallstones
Recognise the presenting symptoms of pancreatitis
Severe epigastric pain
Radiating to the back
Relieved by sitting forward
Aggravated by movement
Associated with anorexia, nausea and vomiting
IMPORTANT: check whether the patient has a history of high alcohol intake or gallstones
Signs of acute panc on examination?
Epigastric tenderness
Fever
Shock/ signs of hypovolaemia (includes hypotension, tachycardia and tachypnoea)
Decreased bowel sounds (due to ileus)
In severe pancreatitis:
Cullen’s sign (periumbilical bruising)
Grey-Turner sign (flank bruising)
Invx for acute panc?
Blood:
VERY HIGH SERUM AMYLASE (this does not correlate with severity) usually at least 3x normal limit
High WCC
High CRP
U&Es (to check for dehydration)
High glucose
Low Calcium (saponification - calcium binds to digested lipids from the pancreas to form soap)
LFTs (may be deranged if gallstone pancreatitis or alcohol)
ABG (for hypoxia or metabolic acidosis)
USS: check for evidence of gallstones in biliary tree
Erect CXR: may be pleural effusion. Also to check for bowel perforation
AXR: exclude other causes of acute abdomen
CT Scan: if diagnosis is uncertain or if persisting organ failure
1st line Treatment for ac panc?
1st line
1A. Resus; Hartman’s or saline
- catheter to monitor urine output for sever cases
- blood transfusion if haemmorhage
1B. Analgesia ; Morphine sulphate iv
1C. Nutrition;
- parenteral if cant do oral
consider empirical ABX
Some patients may also need; antiemetic; ondansetron calcium replacement; calcium gluconate mg replacement insulin
this is done for all patients regardless of aetiology
Treatment for ac panc with gallstones?
If with gallstones;
- cholecystectomy; remove gbladder
Treatment for ac panc with gallstones and cholangitis?
ercp
Treatment for ac panc , alcohol induced?
councelling
alcohol withdrawal prophylaxis ; Lorezapam
vitamin n mineral replacement;
- thiamine
- folic acid
- cyanocobalamin
Treatment for ac panc , infected and necrotic?
iv abx
catheter drainage
necrosectomy, debridement
some scores used to grade SEVERITY of acute pancreatitis?
Modified Glasgow Score (combined with CRP (> 210 mg/L)
APACHE-II Score
Ranson score
Balthazar score - based on CT
why can acute pancreatitis cause a pleural effusion?
a blocked pancreatic duct can lead to a leak and formation of a pancreaticopleural fistula
effusion usaully left sided
