Pancreas CIS Flashcards
criteria to dx acute pancreatis
(2 out of the 3)
- lipase level 3x the ULN
- epigastric pain
- changes on CT
acute pancreatitis- etiolgoy
- gallstones
- heavy alcohol use
- hypertriglyceridemia
- trauma
- ERCP
saponification
in acute pancreatitis!
-interaction of cations with free fa’s released by the action of activated lipase on triglycerides in fat cells–> low blood calcium!!
amylase- elevated in other conditions
- high intestinal obstruction
- gastroenteritis
- mumps
- ectopic pregnancy
- opioids
- after abd surgery
acute pancreatitis- severity assessment
- Ranson criteria
- apache II (>8= higher mortality)
- atlanta classification
- CT grade of severity index
acute pancreatitis- independtly assoc with inc mortality
-SIRS and elevated BUN on admission with a rise in BUN within first 24 hrs of hospitalization
Ranson criteria- 3 or more- severe course with pancreatic necrosis
(acute pancreatitis) GA-LAW- at admission -Glucose >200 -Age>55 -LDH> 350 -AST >250 -WBC > 16,000
Ranson criteria- development of the following in the first 48 hrs indicates a worsening prognosis
C & HOBBS (48 hrs after admission)
- Calcium < 8
- Hematocrit drop > 10%
- oxygen (paO2) < 60
- Base deficit > 4
- BUN increase > 5
- sequestration of fluid > 6L
Ranson criteria- number of criteria and mortality rate
- 0-2- 1%
- 3-4- 16%
- 5-6- 40%
- 7-8- 100%
Atlanta criteria
(acute pancreatitis)
- mild- no organ failure, no local complications (fluid, pseudocyst, necrosis, pleural effusion)
- moderate- transient organ failure < 48 hrs, local complications +/-
- severe- persistent organ failure > 48 hrs
acute pancreatitis- imaging signs- xray
- “sentinel loop”- air filled small intestine
- “colon cutoff sign”- gas filled segment of transverse colon abruptly ending at area of pancreatic infl
acute pancreatitis- unenhanced CT
-demonstrate enlarged pancreas when dx is uncertain
acute pancreatitis- rapid-bolus IV contrast-enhanced CT
- ID areas of pancreatic necrosis
- should be avoided when serum Cr > 1.5!!!
severe acute pancreatitis- complications
- intravascular volume depletion
- pleural effusion
- necrosis
- pseudocysts
- ARDS
risk factors in SAP for high levels of fluid sequestration
- younger age
- alcohol etiology
- higher hematocrit value
- higher serum glucose within 48 hrs of admission
- SIRS
