Q

CARING FOR THE PATIENT - ERCP

A
  • Conscious Sedation
  • Initially, patient placed in the left side-lying position with knees flexed
    — Then, once the endoscope is placed in the duodenum, the patient will be positioned in a prone or semi-prone position
  • Patient may experience abdominal discomfort for a few hours following the ERCP
  • Complications: Pancreatitis, sepsis, hemorrhage, aspiration

Q

LAPAROSCOPIC CHOLECYSTECTOMY

A
  • Removal of the gallbladder is performed through a small incision or puncture made through the abdominal wall at the umbilicus.
  • Four incision sites
  • Abdominal cavity is inflated with carbon dioxide to assist in inserting the laparoscope and aid in visualizing the
    abdominal structures.
  • Once the cystic duct is dissected, the common bile duct will be visualized by ultrasound or cholangiography to evaluate the anatomy and identify stones
  • Gallbladder is then removed after the bile and small stones are aspirated

A

Nursing goals
* Treat pain
* Relieve nausea and vomiting
— Gastric Decompression
— Antiemetics
* Provide comfort and emotional support
* Maintain fluid and electrolyte balance and nutrition
* Observe for complications

18
Q

what is acute pancreatitis

A

Inflammatory process of the pancreas due to activated pancreatic enzymes
* Self-digestion of the pancreas by its own proteolytic
enzymes (Trypsin)

19
Q

common causes of acute pancreatitis

A
  • Gallbladder disease (gallstones)**
  • Alcohol abuse**
  • Drug use
  • Trauma
  • Viral infections (Cytomegalovirus (CMV), Mumps)
  • Peptic ulcer disease
  • Hyperlipidemia
  • Prescribed medications
  • Surgery
20

interprofessional care for acute pancreatitis

A

Goals include:
* Relieving pain and discomfort
* Prevention or alleviation of complications
* ↓ Pancreatic secretions to minimize pancreatic stimulation
* Hydration
* Correction of fluid/electrolyte imbalance
* Prevention/treatment of infections
* Removal of precipitating cause

23
Q

NURSING MANAGEMENT – RELIEVING PAIN & DISCOMFORT of acute pancreatitis

A
  • Goal: Decrease secretion of pancreatic enzymes to relieve pain
  • Analgesics
  • NG Tube Suctioning
    — Used to relieve severe nausea/vomiting and/or treat
    abdominal distention
  • Bed rest
    — Decrease metabolic rate & decrease secretions of
    pancreatic and gastric enzymes
24
Q

NURSING MANAGEMENT – IMPROVING NUTRITIONAL STATUS of acute pancreatitis

A
  • NPO with enteral nutrition
    — Prevents pancreatic enzyme release, maintains gut integrity, enhances immune system functioning, and demonstrates lower complication rates
  • Daily weights
  • Electrolyte levels
  • CBGs every 4-6 hours
  • Oral feedings will gradually be reintroduced as acute symptoms subside
    — Diet high in carbohydrates and low in fats/proteins
    — Avoid heavy meals and alcoholic beverages
25
Q

NURSING MANAGEMENT – POTENTIAL COMPLICATIONS of acute pancreatitis

A
  • Fluid & Electrolyte Imbalances
    — Assessing skin turgor, moistness of mucous membranes, daily weights, fluid intake and output, NG secretions
  • Hypocalcemia
    — Monitor for Chvostek’s Sign
    — Monitor for Trousseau’s Sign
  • Hypomagnesemia
  • Pancreatic Necrosis
  • Hypovolemic Shock
  • Septic Shock
26
Q

WHAT ARE ESOPHAGEAL VARICES?

A
  • Dilated, tortuous veins found in the lower esophagus, but can develop higher in the esophagus or extend into the stomach
  • Develop due to portal hypertension in relation to liver
    disease
27
Q

clinical manifestations of esophageal varices

A

Bleeding Esophageal Varices:
* Hematemesis
* Melena
* Deterioration in mental and physical status
* History of alcohol use disorder
Hypovolemic Shock
* Decreasing urine output
* Oliguria
* Hypotension
* Decreased pulse pressure
* Flat neck veins
* AMS
* Delayed capillary refill
* Pallor
* Tachycardia
* Tachypnea

28
Q

diagnostics of esophageal varices

A

Esophagogastroduodenoscopy (EGD)
* Assess variceal size, location, and variceal features
— Variceal size helps determine pharmacologic and endoscopic therapies to prevent/manage risk of bleeding
* Acute Care Setting: Procedure typically occurs within 12
hours after stabilization of patient

29
Q

nursing management of esophageal varices

A
  • Continuous vital sign monitoring
  • Signs/Symptoms of Hypovolemia
  • CVP Monitoring
  • ABG’s
  • Intravascular volume depletion
  • Urine Output
30
Q

pharmacologic therapy of esophageal therapy

A

Antibiotic Therapy
* IV Ciprofloxacin
* IV Ceftriaxone
Octreotide
Somatostatin
Non-selective Beta-Blockers
* Propranolol, Nadolol, Timolol, Carvedilol
IV Vasopressin
* Used in conjunction with IV Nitroglycerin

31
Q

ENDOSCOPIC THERAPIES for esophageal varices

A

Esophageal Banding Therapy (Variceal Band Ligation)
* EGD
* Elastic Rubber Band
* Most effective therapy in treating acute hemorrhage of varices
Endoscopic Injection Sclerotherapy
* Sclerosing agent injected into bleeding esophageal varices to promote thrombosis and eventual sclerosis
* Only used to treat acute variceal bleeding if esophageal banding cannot be done
Balloon Tamponade
* Temporary measure to control bleeding during an
active hemorrhage
* Pressure exerted on the upper portion of the stomach and against the bleeding varices by a double balloon
tamponade
* Lethal Complications: Esophageal rupture, aspiration, rebleeding
Transjugular Intrahepatic Portosystemic Shunting (TIPS)
* Used in patients if medications and band ligation are
unsuccessful
* Controls acute variceal hemorrhage by lowering portal
pressure
* Allows blood flowing into the liver from the portal vein to
flow through the TIPS stent directly into the hepatic vein,
which is the vein that drains blood out of the liver. This
reduces portal hypertension.

32
Q

POST-ENDOSCOPIC THERAPIES

A

Medications
* Antacids
* Histamine-2 Antagonists
* PPI
