Q

Interstitial pancreatitis affects the majority of patients and It is characterized by

A

a lack of necrosis.
diffuse enlargement of the gland due to inflammatory edema.
The inflammation is confined to the pancreas itself.

Q

Necrotizing Pancreatitis is characterized by

A

tissue necrosis
damage to blood vessels
bleeding and thrombosis
extends beyond the pancreas

18
Q

patients with Necrotizing Pancreatitis are at risk for?

A

Organ failure
GI bleed
Shock
Fluid collection

19
Q

what are risk factors for developing pancreatitis?

A
  1. blunt abdominal trauma
  2. alcohol abuse
  3. oral contraceptives
  4. tabacco
  5. use of diuretics
  6. corticosteroids
  7. hyperlipidemia
  8. hypercalcemia
20
Q

clinical manifestation of pancreatitis

A
  1. severe abdominal pain
  2. cullen’s sign
  3. Gary-turner’s sign
  4. hypotension related to hypovolemia
  5. tachycardia, cyanosis, cold clammy skin
  6. respiratory distress & hypoxia
21
Q

what type of pain associate with pancreatitis?

A

severe abdominal pain,
mostly post meals (24-48 hours),
not relieved by antacids.

22
Q

abdominal rigidity is an indication of?

A

peritonitis

23
Q

gary-turners sign is?

A

bruising on the sides of the patient when you TURN them. Indicating internal bleeding.

24
Q

cullens sign is

A

C shaped bruising around the umbilicus

25
Q

clammy skin means

A

wet skin due to sweating

26
Q

The diagnosis of acute pancreatitis is based on the fulfillment of two out of the three following criteria:

A
  1. a history of upper abdominal pain,
  2. 3x increase in serum amylase or lipase levels
  3. findings on imaging (CT, MRI)
27
Q

abscesses are seen via which imaging methods?

A

CT and MRI. Not X-rays

28
Q

what other diagnostic lab work is used to assess pancreatitis?

A
  1. Hgb and Hct levels (decreased for bleeding)
  2. elevated WBC
  3. Hypocalcemia
  4. increased levels of pancreatic enzymes
29
Q

What additional procedure might be used to visualize and treat?

A

ERCP

30
Q

there are three degrees of pancreatitis severity:

A
  1. mild
  2. moderately severe
  3. severe acute
31
Q

(1) mild pancreatitis

A

the absence of organ failure and no local or systemic complications

32
Q

(2) moderately severe pancreatitis

A

the presence of short-term organ failure or local or systemic complications,

33
Q

(3) severe acute pancreatitis

A

characterized by persistent organ failure

34
Q

Medical management of acute pancreatitis starts with

A
  1. NPO to inhibit pancreas stimulation
  2. (NG) tube is used for nutrition
  3. pain relief using parenteral opioids such as morphine, fentanyl
  4. respiratory care
  5. Biliary drainage
35
Q

respiratory care for Medical management of acute pancreatitis includes:

A
  1. monitoring arterial blood gases (ABG)
  2. using humidified oxygen
  3. intubation & mechanical ventilation
36
Q

biliary drainage for Medical management of acute pancreatitis includes:

A
  1. Placement of biliary drains (for external drainage)
  2. stents (indwelling tubes) in the pancreatic duct
    to reestablish drainage of the pancreas. This has resulted in decreased pain.
37
Q

Surgery for pancreatitis is performed to

A

to establish pancreatic drainage;

or to resect or débride an infected, necrotic pancreas

38
Q

what type of feeding given, and medication restriction must be followed post acute pancreatitis management includes:

A
  1. Oral feedings that are low in fat and protein are initiated gradually.
  2. Caffeine and alcohol are eliminated from the diet.
  3. discontinuing risk factor medications (corticosteroids, oral contraceptives)
  4. follow-up x-ray and ERCP
39
Q

nursing bedside interventions for a hospitalized acute pancreatitis

A
  1. semi-fowler position (decrease pressure on diaphragm)
  2. frequent repositioning (prevent respiratory secretion pooling)
  3. monitor Pulse Ox (ABG)
  4. assess pain
  5. monitor Blood Glucose q4-6h
  6. assess drainage sites (infection)
  7. assess skin (hydration/turgor, jaundice)
40
Q

a major cause of morbidity and mortality in patients with acute pancreatitis is

A

Pancreatic necrosis

41
Q

Pancreatic necrosis requires

A

surgical, percutaneous or endoscopic débridement
