Study Notes
Preoperative Nutrition
- Importance:
- Optimal nutrition status prior to surgery improves postoperative outcomes
- Reduces risk of complications, length of stay, and mortality
- Goals:
- Ensure adequate nutrition to support wound healing and recovery
- Optimize immune function and reduce infection risk
- Interventions:
- Nutritional screening and assessment
- Individualized nutrition plans
- Oral nutrition supplements (ONS) and immunonutrition
Postoperative Nutrition
- Importance:
- Adequate nutrition essential for wound healing, tissue repair, and recovery
- Reduces risk of complications, readmissions, and mortality
- Goals:
- Support protein synthesis and muscle function
- Meet increased energy and protein needs
- Interventions:
- Early enteral nutrition (EN) or parenteral nutrition (PN) initiation
- ONS and immunonutrition
- Monitoring of nutrition status and adjustment of nutrition plans
Parenteral Nutrition (PN)
- Definition:
- Intravenous administration of nutrients, including protein, carbohydrates, fats, vitamins, and minerals
- Indications:
- Inability to tolerate enteral nutrition (EN)
- Intestinal failure or obstruction
- Severe malnutrition or cachexia
- Components:
- Amino acids (protein)
- Dextrose (carbohydrates)
- Lipids (fats)
- Electrolytes, vitamins, and minerals
- Administration:
- Central venous access devices (CVADs)
- Peripheral parenteral nutrition (PPN)
- Home parenteral nutrition (HPN) for long-term therapy
Test your knowledge on the importance of nutrition in surgery, including preoperative and postoperative nutrition, and parenteral nutrition. Learn about the goals and interventions for optimal nutrition status and recovery.
