1
Q

acute pancreatitis

A

>causes autodigestion + severe pain

degree of inflammation varies fr mild edema to severe hemorrhagic necrosis

Q

autodigestive effects of pancreatic enzymes

TRYPSIN

A

activation of trypsinogen to trypsin in the pancreas:

-edema
-necrosis
-hemorrhage

-when it leaks to abdomen, can cause green/yellow/brown discoloration

16
Q

pancreatic pseudocysts prognosis

A

-may be self limiting
-may perforate + cause peritonitis or rupture into stomach

17
Q

pancreatic abscess

A

infected pesudocysts

18
Q

everything is elevated except… from..

A

calcium
from fat necrosis

19
Q

elevated diagnostics

A

-serum/urinary amylase
-lipase
-glucose
-triglycerides

20
Q

primary diagnostic tests

A

serum amylase +lipase
-usually high early + stays high for 24-72 hrs

-lipase is more important

21
Q

best imaging test

A

CT scan

22
Q

Endoscopic retrograde cholangiopancreatography - ERCP

A
  • check for obstruction in bile ducts
23
Q

if paralytic ileus or constipation is present, then avoid which meds/.

A

anticholinergics like ATROPINE
-use spasmolytics likr nitro or papaverine instead

24
Q

reduce/suppress pancreatic enzymes to decrease stimulation by…

A

RESTING
-NPO
-NG tube
-enteral support
-no ETOH/smoking
-low fat, high carb
-limit stress

25
Q

surgical therapy

A

ERCP + sphincterotomy (severingof muscle layers of sphincter of oddi)
-CT/edoscopy to drain severe necrotic fluid collection

26
Q

why do we not give parenteral nutrition?

A

because high risk for infection

27
Q

MEDICATION FOR PANCREATITIS

A

-antacids> decr secretion
-antispasmodics (dicyclomin)
-carbonic anhydrase inhibitors (acetazolamide)
-morphine
-PPI omeprazole> decr HCl secretion
-pancrelipase> replace penzymes

28
Q

best position for pain relief

A

-flex trunk
-draw knees up

-side lying w head up 45 degr
