Electrolytes

BUN

CBC

Liver enzymes

Dressing change

  1. Per policy
  2. Site observation is key!!

Refeeding syndrome

Infusion pump must be used

Q

What are S/S of infection and sepsis with PN? and interventions if suspected?

A

Local manifestations - Erythema, Tenderness, Exudate at catheter insertion site

Systemic - Fever, chills, Nausea/vomiting, Malaise

If suspected:

  • Blood and catheter cultures if infection suspected
  • X-ray: To check changes in pulmonary status
  • After PN therapy, daily dressing changes to infusion site until it fully heals (After catheter is removed)

17
Q

Gastric banding

A

restrictive surgery that limits the size of the stomach with an inflatable band, adjustable

  • Port is subcutaneous that can be inflated or deflated by fluid injection in provider’s office
  • Creates sense of fullness
  • Delays in stomach emptying
  • Can be modified or reversed later
18
Q

Sleeve Gastrectomy

A

restrictive surgery in which 75% of stomach is removed, leaving a sleeve-shaped stomach

  • Stomach function preserved
  • Eliminates hormones made in the stomach that stimulates hunger
  • Currently requires a surgical incision, research ongoing on laparoscopic approach
  • Leakage related to stapling or sutures possible
  • NOT reversible
19
Q

Plication

A

restrictive surgery in which a 2. sleeve is created by suturing rather than removing stomach

  • Minimally invasive surgery (compared to sleeve gastrectomy)
  • Involves folding stomach wall inward, reducing the stomach volume
  • Reversible
  • Requires hospital stay
  • Nausea common after procedure
  • Blockage may occur from swelling or fold too tight
20
Q

Intragastric Ballon

A

A restrictive procedure in which a balloon occupies space in the stomach

  • Natural anatomy of the stomach is not altered
  • Patients feel more full, appetite decreased
  • Less invasive, placed using - - Balloon filled with saline, varying amounts can be used (400-700 mL) –OR- nitrogen gas (newer)
  • Can only be left in for 6 months
21
Q

Roux-en-Y Gastric Bypass

A

a combination surgery in which a stomach pouch is created, connected to jejunum, rest of stomach and first part of small intestine bypassed

  • Food bypasses 90% of the stomach, duodenum, and a small segment of jejunum
  • **Most common bariatric procedure **
  • Excellent patient tolerance
  • Has low complication rates
22
Q

Possible complications of Roux-en-Y Gastric Bypass surgery:

A
  1. DUMPING SYNDROME
    - also called rapid gastric emptying
    - causing abdominal cramps and nausea and diarrhea, due to insulin surge, symptoms of hypoglycemia occur 2-3 hours later
    - Avoidance of sugary foods, small frequent meals and dietician referral can all help
  2. LEAK AT ANASTOMOSIS SITE - this is a concern for every stomach surgery procedure!
  3. ANEMIA
23
Q

Preoperative Care for a Bariatric surgery:

A

Patients will likely have comorbidities, so team approach

Nurse myst prepare the room!
1. Have room ready for patient before arrival
- Larger blood pressure cuff
- Larger gown
- Patient transfer equipment
- Wheelchair with removable arms
(Note: Don’t make a large pt uncomfortable by making them feel like you have to provide special accommodations “Oh, I need a larger bp cuff, let me get it!” :O )

  1. Wound infection – skin prep important
  2. Breathing - Coughing, Deep breathing, Turning - These are super important in obese patients to avoid pulmonary complications*
  3. Venous access -> Have an extra long catheter
  4. Mechanical ventilation
24
Q

Postoperative care for Bariatric Surgery:

A
  1. Close observation for complications
  2. Transfer with specially trained personnel
  3. Stabilize airway -
    * *Elevate HOB to 35-40 degrees**
  4. Adipose tissue problems
    - Anesthetic agents stored in adipose tissue, may be slower to wake and/or re-sedation possible
    - Excess adipose tissue compresses chest and abdomen which Causes CO2 retention
  5. Manage pain
  6. Diligent turning and ambulating
  7. Hypoxemia, pulmonary hypertension, polycythemia
  8. Risk for deep venous thrombosis (DVT)
    - TED hose and PCD devices should be put on at night or when pt is NOT moving around
  9. Infection, dehiscence, delayed healing
    - Nutrition is KEY!!
  10. Keep skin folds clean and dry to prevent bacterial or fungal infections
  11. Attentive to placement of NG tube
  12. Careful transition to new diet
25
Q

Post Bariatric Surgery diet is generally:

A
High protein 
Low carbohydrates 
Low fats
Low roughage 
6 small feedings
Fluids not to be ingested with meals and <1000 ml/day
26
Q

What are later complications of bariatric surgery?

A
Anemia 
Vitamin deficiencies 
Diarrhea 
Psychologic problems
Peptic ulcer formation
Dumping syndrome
Small bowel obstruction 

*Long-term follow-up care important
