For decades, patients were told not to eat or drink anything after midnight before surgery. However, modern surgical science has evolved. Today, many hospitals following the ERAS (Enhanced Recovery After Surgery) protocol recommend consuming a preoperative carbohydrate drink up to 2 hours before surgery.
But why is this recommended? And how does it improve surgical outcomes? Let’s break it down scientifically.
Traditional Fasting vs Modern ERAS Approach
Traditional surgical fasting aimed to reduce the risk of aspiration. While safety is critical, prolonged fasting leads to increased insulin resistance, dehydration, and muscle loss. The ERAS protocol changed this by allowing clear carbohydrate drinks up to 2 hours before anaesthesia, improving metabolic response without increasing risk.
What Happens During Prolonged Fasting?
When a patient fasts for long hours, the body enters a catabolic state, accelerates muscle breakdown, and makes blood sugar regulation unstable. This stress response delays postoperative recovery.
How Preoperative Carbohydrate Drink Helps
Drinking a carbohydrate solution before surgery helps the body remain metabolically stable. Key benefits include:
- Reduce postoperative insulin resistance
- Maintain muscle strength and function
- Improve overall patient comfort and hydration
- Support faster mobilization after surgery
Why Exactly 2 Hours?
The "2-hour rule" is based on gastric emptying research. Modern maltodextrin-based drinks are designed to empty from the stomach within 2 hours, making them safe for anaesthesia while providing controlled energy release.
Scientific Composition
Medical-grade ERAS drinks like Surgicarb™ contain complex carbohydrates (maltodextrin) and electrolytes with controlled osmolality, unlike regular sugary beverages.
Benefits for Hospitals and Patients
Faster Recovery
Patients return to normal activity more quickly.
Patient Comfort
Reduces preoperative thirst, hunger, and anxiety.
Frequently Asked Questions
Is it safe for all surgeries?
ERAS protocols are implemented under medical supervision. High-risk patients or emergency surgeries may require modified protocols.
Is plain water enough?
Water helps hydration, but carbohydrate drinks provide the metabolic energy needed to reduce surgical stress.
