Prepare Better. Recover Faster. The Role of Nutrition Before Surgery

Surgery places significant metabolic demands on the body. Preparing nutritionally before surgery can help patients enter the operating room in a better physiological state—and support recovery afterward.

Moving Beyond Traditional Fasting

Enhanced Recovery After Surgery (ERAS®) is a multidisciplinary approach built around evidence-based practices designed to improve the surgical experience, reduce complications and support faster recovery.

One important component is preoperative carbohydrate loading.

Traditional fasting can leave patients in a fasted state before surgery, increasing metabolic stress and contributing to insulin resistance, muscle and protein loss, hunger, thirst and discomfort.

ERAS® guidelines support the use of a complex carbohydrate drink before anesthesia in appropriate patients, helping maintain a fed state rather than prolonged fasting.

Introducing ENROUTE® PREPARE

ENROUTE® PREPARE is a preoperative complex carbohydrate drink designed to support patients before surgery.

By providing carbohydrate before surgery, PREPARE helps support the body's metabolic response during a period of significant physiological stress.

Evidence associated with preoperative carbohydrate loading has demonstrated potential benefits including:

  • Reduced postoperative insulin resistance

  • Preservation of lean muscle mass

  • Reduced protein and nitrogen loss

  • Reduced hunger, thirst and anxiety

  • Reduced postoperative nausea and vomiting

  • Support for muscle strength and recovery

  • Potentially shorter hospital stays

Simple preparation. Purposeful nutrition.

Mix one serving of ENROUTE® PREPARE with 400 mL (13.5 fl oz) of water, stir or shake until dissolved, and consume according to your surgical team's instructions.

Better preparation starts before surgery.

ENROUTE® PREPARE is part of EMN's evidence-based approach to helping patients prepare better and recover faster.

ENROUTE® PREPARE meets applicable ASA® clear-fluid guidance for preoperative fasting. Use should follow the instructions of the patient's healthcare provider and applicable surgical protocol.
