Enhanced Recovery After Surgery (ERAS) To Improve Recovery
Francesco Carli MD, MPhil Professor of Anesthesia
McGill University
Disclosures
None
Improving Patient’s Recovery What if surgery could be done without:
Metabolic stress response
Catabolism
Organ dysfunction Complications
Pain Fatigue…
…length of stay and costs will decrease too
We’re not there yet
• Complications: 21-45% of patients have complications after cancer surgery and 1-4% die.
• Variations: Significant differences between and within centers in perioperative processes, complications and hospital stay
• Patient centered outcomes: Full recovery takes longer than we think.
Colectomy outcomes remain poor
Schilling, Dimick, Birkmeyer JACS 2008. 207(5):698-704
Prioritizing quality improvement in general surgery
Cohen ME Ann Surg 2009
Variability in long length of stay after uncomplicated colorectal surgery in NSQIP hospitals
87% had no complications: 6.1(3.8) days, median 5 days 13% had complications: 16.1(14.2) days, median 12 days
Variability in Processes of Care: Responses (%) to questionnaire on perioperative care in colonic resection in 5 northern European countries
Response Scotland Netherlands Sweden Norway Denmark Range
NG is removed in OR 75% 22% 83% 82% 85% 22-85%
Epidural analgesia is used routinely on ward

Outcomes that matter to patients recovering from GI surgery
Patients emphasized energy level, functional status (daily routine, recreational activities, endurance) and sleep
Compared to patients, clinicians put more emphasis on symptoms (pain, cognition, bowel function)
Patient Expectations: What day do you tell patients to expect to be
discharged after uncomplicated colon resection?

Surgical stress: pain, catabolism, fluid/salt
retention, immune dysfunction, nausea/vomiting, ileus, impaired pulmonary function, increased
cardiac demands, hypercoaguability, sleep
disturbances, fatigue
Kehlet and Wilmore, Ann Surg 2008 (revised)
Approaches to reduce surgical stress and improving outcomes
Minimally Invasive Surgery
Afferent neural blockade: thoracic epidural
local infiltration anesthesia peripheral nerve blocks
Pharmacologic interventions: non-opioid, multimodal analgesia
anti-emetics glucocorticoids
systemic local anesthetics insulin
β-blockers α2-agonists
anabolic agents
Other interventions: fluid balance
normothermia preoperative carbohydrate
exercise
Perioperative care in GI Surgery: • >20 elements
• “Strong” recommendations
• Several challenge traditions
• Multiple stakeholders
• How do we get all this into
practice?
Lots of evidence
Cole Thompson “Three Silos – Central Colorado- 2007”
“Health care historically has been a very siloed field that’s organized around medical
specialties... The patient is the ping-pong ball that moves from service to service”
-Michael Porter
Enhanced Recovery Pathway
• Integrated, evidence-based, multimodal, consensus on perioperative care
• Goals: – Support early return of function
– Reduce morbidity
– Improve efficiency
– Decrease variability
– Increase value (outcomes/cost)

• Lap foregut pathway • Started in 2001 • Nutrition management • Limited investigations • Excellent patient acceptance
• Colorectal fast track • Started in 2006 • Laparoscopic cases only • Surgeons selected patients • Limited patient education
Mission: Implement multidisciplinary ERPs across department
• Initiated by clinicians, supported by Chair
• Started October 2008
• Target prevalent in-patient procedures
• Pathways would be standard of care (all start pathway)
• Full time coordinator as pilot project (1 year)
• Multidisciplinary team with clinical experts for each pathway
• Weekly meeting
ERP Team: Steering Group
• Pathway coordinator • Surgeon lead • Anesthesia lead • Nurse manager surgery ward • Clinical nurse specialist- pain • Physiotherapist • Nutritionist • Pharmacist • Librarian
PLUS Clinical Experts for each pathway – surgical
lead, anesthesia, nursing
Literature review- guidelines, discharge target Perioperative medical and pharmaceutical orders ADL flowsheets and nursing documentation External prescriptions

Why fasting?
The ”evidence” behind NPO
• Mendelson paper 1946
• Textbook ”thruth” from 1964
But:
• No true scientific backing
• Few aspirations in elective surgery
• Risk: associated with concomitant disease
J R Maltby in Best Practice in Anaesthesia and Intensive Care 2006
Well known physiology: Gastric emptying
Ljungqvist & Söreide, Br J Surg, 90: 400-406, 2003
Gastric emptyng after 400 cc of carbohydrate
MRI Lobo et al. Clin Nutr 2009:28(6)636-41
Why challenge NPO?
• Normal physiology
• NPO is no guarantee of an empty stomach
• The same gastric volume with/without clear fluids
• Improved well being: thirst (headaches, hunger)
Modern fasting guidelines Elective surgery
• Clear fluids – water, coffee, tea (no milk), some juice
• 2 h before anaesthesia & surgery
• Exclusions – Emergency surgery – Upper GI symtoms, GI transit slow
Ljungqvist & Söreide Br J Surg 2003
Cochrane review 2003
• No evidence that liberal fasting guidelines had negative impact on gastric volumes or pH
• Intake of water up to 90 mins preop resulted in lower gastric volumes
• Clinicians should …. when necessary adjust existing fasting policies
PC Stuart in Best Practice in Anaesthesia and Intensive Care 2006
Why carbohydrate treatment?
• Animal work showed survival benefit from fed state in stress
• Short term fasting changes metabolic setting
• Un-natural way to prepare for stress
• Potential metabolic gains…..
Ljungqvist et al, Best Pract & Res Clin Anaesthiol 23 (2009) 401–409
• Reading level of patient education materials: Grade 11.5 Smith & Haggerty, 2003
• 1 out of 5 American adults reads at the 5th grade level or below, and the average American reads at the 8th to 9th grade level, yet most health care materials are written above the 10th grade level
National Patient Safety Foundation, 2011
• Printed materials should be accurate, easily accessible, and at a 6th to 7th grade reading level National Institutes of Health, 2011
• 800 studies between 1970 and 2006 indicate most health materials exceed high-school graduate reading levels Canadian Council for Learning, 2008
Patient Education Is An Important Element
What is Health Literacy? The degree to which individuals can obtain, process and
understand basic health information and services they need to make appropriate health decisions.
Institute of Medicine’s report Health Literacy: Prescription to End Confusion (2004) ;
The U.S. Department of Health and Human Services’ Healthy People (2010)
Prevalence of low Health Literacy
• In the USA- 90 million people- nearly half of the
adult population have low health literacy.
• In Canada-
– 60% of adult Canadians have low health
literacy.
Canadian Council on Learning (2008).; IOM (2004)

How to get ready for your surgery
The evening before your surgery take a shower. The morning of your surgery take another shower. On the day of your surgery do not put any makeup, cream or lotions.
We strongly suggest you stop smoking completely before your surgery, as this will reduce the risk of lung complications afterwards and help the incision to heal. Doctors can help you stop smoking by prescribing certain medications. Please discuss these options with your doctor.
Decrease your alcohol use. Alcohol can interact with medications. Do not drink alcohol 24 hours before surgery. Please let us know if you need help decreasing your alcohol use before surgery.
If you get sick before your surgery please phone the hospital to cancel.
Some pain medications can cause constipation. If constipation becomes a problem, increase the amount of fluids you drink, add more whole grains, fruits and vegetables to your diet and continue to exercise and walk regularly.
