Post Operative Nutritional Care
|
Nutrient Needs for Healing
- Post operative nutrient losses are great, but food intake is diminished.
- Protein losses occur during surgery from tissue breakdown and blood loss.
- Catabolism usually occurs after surgery (tissue breakdown and loss exceed tissue buildup).
- Negative nitrogen balance may occur.
Need for Increased Ptotein
- Building tissue for wound healing
- Controlling shock
- Controlling edema
- Healing bone
- Resisting infection
- Transporting lipids
Problems Resulting From Protein Deficiency
- Poor healing of wounds and fractures
- Rapture of suture lines (dehiscence)
- Depressed heart and lung function
- Anemia, liver damage
- Failure of gastrointestinal stomas to function
- Reduced resistance to infection
- Extensive weight loss
- Increased mortality risk.
Other Post operative Concerns
- Ensure sufficient fluids to prevent dehydration.
- Provide sufficient non protein calories for energy in order to spare protein for tissue building
- Ensure adequate vitamins
- Ensure adequate potassium, phosphorus, iron, zinc.
- Avoid electrolyte imbalances.
Initial Intravenous Fluid and Electrolytes
- Oral feeding is encouraged soon after surgery.
- Routine postoperative intravenous fluids supply hydration and electrolytes, not k calories and nutrients.
