Q

Initial assessment

A
  1. Take history (SOCRATES), AMPLE
  2. Check for risk factors
    Gall stones
    Ethanol
    Trauma
    Steroids and diabetes
    Mump/other viral
    A
    Scoripion
    Hyperlipidemia, hypercalcemia
    ERCP
    Drugs- azathioprine, thiazide
  3. Examination: fever, pulse, BP. Abdominal pain/tender, pleural effusions, pericardial
  4. Ix
    FBC->anemia, DIC, WCC
    UEC->+Cr is poor prognosis
    LFTs->obstruction
    Amylase, lipase elevated 3X ULN
    CMP
    Glucose
    INR
    ABG->hypoxemia, acidosis
    CXR->atelectasis, pleural effusio
    AXR->sentinel loop (isolated dilitation of segment of gut adjacent to pancreas)
    USS->pancreatic inflammation, stranding, calcifications
    Non-contrast CT abdomen, MRCP, ERCP?

Q

Management

A
  1. ABC
  2. Ventilate Oxygen
  3. Cannula
  4. IVF resuscitation->bolus, or 1L over hour
  5. Morphine + metoclopramide
  6. Insert catheter, monitor urine output
  7. Continuous monitoring
  8. Get surgical, medical help
  9. LMWH DVT, TEDs
  10. Monitor UEC, amylase, VBGs, glucose daily. Hourly BO, u/o
  11. Abdominal USS (gall stones), CT (necrosis)
  12. Nutrition
  13. Evidence of necrosis->prophylactic antibiotics
  14. If glucose ++, place on sliding scale
  15. If bleeding, check parametes
  16. Consider calcium and magnesium replacement
