Pancreatitis Flashcards
1
Q
Ranson criteria
A
1. On Admission WBC count >16 000 Glucose >200mg/dL Age >55y AST >250 LDH >350
- Subsequent 48h
Hematocrit fall 10%
Calcium 6L required
Base excess +4, P02
2
Q
Imaging when pancreatitis diagnosis in question
A
Contrast enhanced CT
3
Q
If necrosis seen on CT, what should be started
A
Prophylactic antibiotics
50% will become infected.
4
Q
Following resolution of pancreatitis, what should be done if the person has gall stones
A
Cholecystectomy
5
Q
Initial assessment
A
- Take history (SOCRATES), AMPLE
- Check for risk factors
Gall stones
Ethanol
Trauma
Steroids and diabetes
Mump/other viral
A
Scoripion
Hyperlipidemia, hypercalcemia
ERCP
Drugs- azathioprine, thiazide - Examination: fever, pulse, BP. Abdominal pain/tender, pleural effusions, pericardial
- 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?
6
Q
Management
A
- ABC
- Ventilate Oxygen
- Cannula
- IVF resuscitation->bolus, or 1L over hour
- Morphine + metoclopramide
- Insert catheter, monitor urine output
- Continuous monitoring
- Get surgical, medical help
- LMWH DVT, TEDs
- Monitor UEC, amylase, VBGs, glucose daily. Hourly BO, u/o
- Abdominal USS (gall stones), CT (necrosis)
- Nutrition
- Evidence of necrosis->prophylactic antibiotics
- If glucose ++, place on sliding scale
- If bleeding, check parametes
- Consider calcium and magnesium replacement
7
Q
Modified glasgow criteria
A
PANCREAS Pa02 (need ABG) Age >55 Neutrophilia (FBC w/ differentials) Renal function (UECs) Enzymes (LFTs, LDH) Albumin Sugar (+Glucose)
8
Q
Early complications
A
Shock ARDS Renal failure DIC Sepsis Hypocalcemia Hyperglycemia
9
Q
Late complications
A
- Pancreatic necrosis and psuedocyst= +T, mass, persistent amylase/LFTs->may need drainage
- Abscesses->drain
- Bleeding->embolise
- Thrombosis
- Fistulae
- Recurrent edematous panxreatitis
10
Q
Examination
A
- Evidence of hypovolemia
- Diaphoretic, tachyP, tachyC
- -ve breath sounds, effusion
- Tender abdomen, reduced bowel sound
- SIgns of hypocalcemia rare->facial muscle spasm with Chvosteks sign and carpopedal spasm with Trousseau’s sign
- Cullens signs, Grey turners sign
