Summary
Optimizing metabolic control, particularly managing insulin resistance and hyperglycemia, significantly improves surgical outcomes. Strategies include insulin therapy, epidural blockade, preoperative carbohydrates, and minimally invasive surgery.
Area of Science:
- Metabolic control
- Surgical outcomes
- Perioperative medicine
Background:
- Perioperative metabolism management is crucial for surgical outcomes.
- Postoperative insulin resistance and hyperglycemia are linked to complications.
- Hyperglycemia's toxicity and causal relation to complications are increasingly recognized.
Purpose of the Study:
- To review novel information on metabolic control in the perioperative period.
- To highlight the importance of managing perioperative metabolism for improved surgical care.
Main Methods:
- Review of recent studies on perioperative metabolism.
- Analysis of the impact of hyperglycemia and insulin resistance on surgical outcomes.
- Exploration of strategies to manage perioperative metabolic disturbances.
Main Results:
- Insulin resistance and hyperglycemia correlate with common postoperative complications.
- Insulin therapy improves protein and fat metabolism and may influence other hormones.
- Hyperglycemia exacerbates inflammation via mitochondrial substrate overload and altered gene expression.
- Strategies like epidural blockade, preoperative carbohydrates, and minimally invasive surgery can prevent insulin resistance.
Conclusions:
- Minimizing insulin resistance effects substantially improves outcomes after surgical stress.
- Effective perioperative metabolic control is key to enhancing patient recovery and reducing surgical complications.
