to reduce the risks of SIRS and organ failure

Acute Pancreatitis

11

pancreatic enzyme supplementation

reduction in dietary fat intake

15
Q

Which drug can cause an increase in sphincter of Oddi pressure?

A

Morphine

16
Q

Why should you avoid Demerol in tx of acute pancreatitis?

A

porential of accumulation of a toxic metabolite normeperidine

17
Q

What tx is no longer recommended for acute pancreatitis?

A

prophylactic abx

18
Q

How do you tx pts with ascending cholangitis or necrotizing pancreatitis?

A

B-lactam/B-lactamase inhibitor: piperacillin/tazobactam can be considered for initial treatment before cultures (especially of aspirated collections) if a strong suspicion of active infection.

19
Q

What do you tx acute pancreatitis with if pt has cholangitis and pt is allergic to penicillin?

A

Levofloxacin

20
Q

What should you be vigilant for when giving prophylactic abx in acute pancreatitis?

A

fungal superinfections

21
Q

What are the tx options for chronic pancreatitis?

A

enteric-coated pancreatic enzyme supplements

antisecretory agent + pancreatic enzyme supplementation

22
Q

What can you add to enteric-coated pancreatic enzyme supplements to increase the effectiveness of enzyme therapy for malabsorption and steatorrhea found in chronic pancreatitis?

A

Histamine2-receptor antagonist or proton-pump inhibitor

23
Q

What would adding an antisecretory agent to pancreatic enzyme supplementation help achieve?

A

may increase the effectiveness of enzyme therapy for malabsorption and steatorrhea

24
Q

What are possible chronic pancreatitis txs?

A

Analgesics: tramadol, chronic opioid, gabapentin, pregabalin, SNRIs or TCAs, traditional pancreatic enzyme supplements

Uncoated enzymes (Viokase)

Octreotide

25
Q

Uncoated enzymes (Viokase) may be more efficacious for what sx when given with what other medication?

A

Uncoated enzymes (Viokase) may be more efficacious for pain control (when given with proton pump inhibitors [PPIs] to protect their integrity) compared with coated enzymes, but this strategy is controversial.

26
Q

T/F: There is a theoretical benefit to using PPIs, even with coated enzymes, in patients with vitamin deficiency to allow faster release of enzymes into the proximal duodenum where fat-soluble vitamin absorption occurs

A

True

27
Q

When would you treat pts with corticosteroids?

A

autoimmune pancreatitis

28
Q

When should you administer pancreatic enzymes?

A

during or just after meals

29
Q

T/F: Products containing enteric-coated microspheres or minimicrospheres may be less effective than other dose forms

A

False; Products containing enteric-coated microspheres or minimicrospheres may be more effective than other dose forms

30
Q

Primarily used to treat malabsorption associated with chronic pancreatitis

also used to treat pain from the disease

Which drug?

A

Pancreatic Enzymes

31
Q

Relief of pain is thought to be due to their ability to break down CCK

Which drug?

A

Pancreatic Enzymes

32
Q

T/F: the release of CCK, which causes an increase in pancreatic secretion, is not inhibited by trypsin
