Enhanced recovery after surgery (ERAS®)
Enhanced Recovery After Surgery (ERAS®) is a multidisciplinary approach, aimed at improving the experience and well-being of patients undergoing surgery. Originally developed in colorectal surgery, it was found that patients following an ERAS programme had fewer complications, a more rapid return of gut function and a shorter hospital stay1. Following success in colorectal surgery, ERAS programmes have been developed in other specialist areas such as urology, pancreatic, orthopaedic surgery and more.
ERAS can benefit the patient as it encourages them to be more involved in their own treatment, promotes shorter recovery times and earlier discharge from hospital 1, 2, 3. It also benefits the hospital by aiding decreased hospital stays 1, 2, 3, 4, hospital acquired infections5 and waiting times2.
Prior to surgery, patients require optimal nutrition to ensure they are in the best possible condition. The National Institute for Clinical Excellence (NICE) state that a malnourished individual will have 3 times the number of complications and 4 times the risk of death from the same surgery as a well-nourished patient6.
Pre-operative carbohydrate loading
Fasting, typically nil-by-mouth from midnight before surgery was introduced to reduce the risk of pulmonary aspiration. However, the European Society for Parenteral and Enteral Nutrition (ESPEN) and NICE state that allowing patients to eat up to 6 hours prior to surgery and being able to drink appropriate fluids up to 2 hours before surgery is safe 7, 6, enabling the patient to enter surgery in a fed state.
Carbohydrate loading before surgery has the following potential benefits:
- Helps prevent dehydration8, 9
- Helps prevent catabolism, insulin resistance, muscle loss, weakness and fatigue and may also reduce the patient’s anxiety and improve comfort 2, 4, 10, 11, 12
- Promotes gut function2, 1
Local ERAS recommendations may vary, please check with your hospital team.
Preload™ is a neutral-tasting carbohydrate loading drink mix specifically designed for use before elective surgery. Preload is presented in 50g pre-measured sachets which when added to water produces a solution with low osmolality.
Providing optimal nutrition in the days following the operation is important to aid recovery. Pro-Cal shot® is a high calorie, low volume supplement which can be given post-operatively. A clinical trial regarding the use of Pro-Cal shot in postoperative patients showed a significant improvement in total daily oral calorie intake and a decreased postoperative hospital stay 13.
