69
Q

Dumping syndrome

A

–
–
– –
Gastric chyme enters small intestine as large hypertonic bolus; pulls fluid into bowel lumen causing decreased plasma volume, distention of bowel lumen, and rapid transit within 15 to 30 minutes of eating
See weakness, sweating, palpitations, dizziness, cramping, borborygmi, and defecation urge
Lasts about 1 hour
Reduced with rest after eating

70
Q

Postprandial hypoglycemia—variant of dumping syndrome

A

– –Uncontrolled high carbohydrate bolus enters small intestine causing excess insulin and resulting in hypoglycemia ~ 2hours after eating
See: sweating, weakness, confusion, palpitations, tachycardia, anxiety (hypoglycemia reaction)

71
Q

Bile reflux gastritis—after reconstruction or removal or pylorus - what meds to give? (bile reflux gets chole)

A

–
– – Bile reflux causes damage to gastric mucosa, chronic gastritis, and PUD
See: epigastric distress temporarily relieved with vomiting Administer cholestyramine—binds bile salts

72
Q

pre op care - gastric surgery

A

Teach patient about procedure and postoperative expectations

■ IV fluids

73
Q

gastric surgery - post op care - splinting?

A

– Fluid and electrolyte balance

Monitor for complications (especially if obese):

■ Anastomosis leak—tachycardia, dyspnea, fever, abdominal pain, anxiety, restlessness
– Requires immediate treatment to prevent sepsis and death ■ Hemorrhage—VS, NG aspirate

75
Q

post op care - gastric surgery - NG tube- what does it do?

A

NGT for decompression; reduces pressure to suture line; decreases edema and inflammation

76
Q

gastric surgery - post op nutrition

A

■ Dietician consult; reinforce instructions
■ Enteral feedings or parenteral nutrition
■ Wound healing: potassium, vitamins C, D, K, and B-complex

77
Q

gastric surgery - post op - Pernicious anemia (cobain has anemia)

A

Pernicious anemia—loss of intrinsic factor; needed for absorption of cobalamin in terminal ileum; essential for RBCs
– Administer cobalamin, multivitamins with folate, calcium, vitamin D, and iron (life-long therapy)

78
Q

gastric surgery - Reduced stomach size means reduced meal size (can gast have water?)

A

– First few weeks: soft, bland, low fiber, high complex carbohydrates, and high
protein
– Small, frequent meals
– No fluids with meals, chew thoroughly
– Avoid simple sugars, lactose, and fried foods
– Avoid extreme food temperatures
– Avoid hypoglycemia—limit sugar with meals; moderate protein and fat

79
Q

esophageal cancer surgery - coughing and turning? and bed position?

A

▪ Turning, coughing, and deep breathing every 2 hours
▪ Incentive spirometer use
▪ Positioned in semi-Fowler’s or Fowler’s
▪ Should be maintained at least 2 hours after eating
▪ Monitor for complications

80
Q

post op - gastric surgery - NG tube - drainage? (Had gastric surgery at 23 and 75)

A

Observe gastric aspirate: color, amount, odor
Bloody drainage expected for 2 to 3 hours; report excess (greater than 75mL/hr); monitor for clots/obstruction;

81
Q

post op - gastric surgery - NG tube - irrigation? color of exudate? (Back to normal at 36)

A

irrigate with NSS to avoid: rupture of sutures, leakage into peritoneal cavity, hemorrhage, and abscess formation
Should darken and change to yellow-green in 36 to 48 hours
