Questions regarding
perioperative nutrition:
• TNP vs EN ?
• Pre- vs post- vs pre- and postoperative ?
• Standard vs immunonutrition ?
ESPEN RECOMMENDATIONS
Preoperative
All malnourished patients
All cancer patients
Scheduled for upper gastro-intestinal surgery
No matter the nutritional status
Preoperative enteral (immuno)nutrition
for 10–14 days
RECOMMENDATION GRADE
A
ASPEN RECOMMENDATIONS
Perioperative
Only moderately/severely malnourished patients
scheduled for elective surgery
Imposibility of meeting nutritional needs > 7-14 days
Early postoperative enteral (delayed PN) nutrition
Rationale for
PREOPERATIVE NUTRITIONAL SUPPORT
PRO
– Malnourished pts → at risk of postoperative complications
– Reduced nutrient intake →frequent in cancer pts and correlates
with nutrition status and complications
– Although malnutrition usually develops over weeks/months → a
short course of nutrition support can improve physiologic
functions
– Preoperative nutrition support →better tolerance for
postoperative nutrition
– Preoperative glucose → reduced postoperative insulin resistance
Rationale for
PREOPERATIVE NUTRITIONAL SUPPORT
CON
– The nutritional status of cancer patients correlates with disease
stage and cancer control
– If nutritional depletion is the result of metabolic use of nutrients
→ the benefit ??
– Short-term refeeding → reversal of long-term malnutrition??
– Preoperative nutrition increases the length of preoperative stay
and increases the costs
Who should receive
preoperative nutrition support?
• The patient should be moderately/severely
malnutrished
• The procedure should be one in which nutrition
support has been shown to improve outcome –
thoraco-abdominal surgery
• Surgery should be elective and safe to delay for 710days
• The enteral route is always prefered (when
possible)
• Combination with postoperative nutrition
• Immune-enhancing formulas
Preoperative nutrition
 Malnourished patients should receive nutritional support
 oral supplements
 enteral nutrition
 Immunonutrition 5 -7 days preoperatively
 reduce the prevalence of infectious complications in patients
undergoing major open abdominal surgery

Preoperative fasting
“While it is desirable that there should be no solid matter in
the stomach when chloroform is administered, it will be found
very salutary to give a cup of tea about 2 h previously.”
Joseph Lister . On anaesthetics, Holmes' system of surgery.
Vol 3, 3rd ed. London: Longmans Green and Company, 1883
Preoperative fasting
Standard practice – fasting from midnight
 reduce the volume and acidity of stomach contents
 decrease the risk of pulmonary aspiration
But …
Ljungqvist & Söreide, Br J Surg, 2003; 90: 400-406
Preoperative fasting
Standard practice – fasting from midnight
 reduce the volume and acidity of stomach contents
 decrease the risk of pulmonary aspiration
But …
Thirst, headaches, hunger
 Cochrane review of 22 RCTs
fasting from midnight
 no reduction in gastric content
 no rise in pH of gastric fluid
clear fluids until 2h before anesthesia
Brady M, et al. Cochrane Database Syst Rev 2003;(4). CD004423.
Why challange
fasting by midnight?
 Normal physiology
 Is no guarantee of an empty stomach
 The same gastric volume with/without clear fluids
 Improved well being
Preoperative fasting
Standard practice
Fasting from midnight
 Reduce the volume and acidity of stomach contents
 Decrease the risk of pulmonary aspiration
Modern fasting guidelines
Clear fluids 2 h before anaesthesia
– Exclusions
 Emergency surgery
Eur J Anaesthesiology 2011;28:556-569
What are
the effects
of the
preoperative fasting ?
Preoperative fasting and perioperative fluids
• If fasted – risk of dehydration
• Dehydration and anesthesia -> hypotension
• Hypotension -> more fluids infused
• Overload of fluids
• Preop clear fluids -> less iv fluids ->
improved outcomes

Preoperative carbohydrates, fluids and outcomes
• Main factors for better outcomes:
Preop carbohydrates & fluid balance
• Preop carbohydrates ->
Less fluid overload (450 ml)
• For every litre extra*: 32% increased risk of
complications (cardiovascular)
* Limit: Day of surgery: Colonic 3,000 ml, Rectal 3,500 ml
Gustafsson et al, Arch Surg 2011
Fluid requirements are different
Open laparatomy
• Increase fluid shifts
• Bowel handling
• SIRS
Laparoscopy
• CO reduction
• Head-down position
• Pneumoperitoneum
Fluid shifts should be minimised
 Avoid bowel preparation
 Maintain hydration till 2 hours before surgery
 Minimise bowel handling
 Avoid blood loss
Goal Directed Therapy

to guide iv fluid
alone or in combination with inotropics

Postoperative analgesia
• Optimale analgesic regimen
– Good pain relief
– Reduction of cardiovascular, cognitive, endocrino –
metabolic complications in at risk patients
– Decrease the risk of chronic pain
– Allow early mobilisation
– Allow early return of gut function and feeding
Postoperative analgesia
• Principles of Multimodal Analgesia
– Avoidance of iv opioids
– Regional anesthesia techniques
• Thoracic epidural analgesia (TEA)
• Spinal analgesia
– Local anesthetic techniques
• Transversus abdominis plane (TAP) block
• The analgesic regimen is specific to the type of
surgery/incision
Postoperative analgesia
in open surgery

Thoracic epidural anesthesia (TEA)
– Middle thoracic (T7-T10)
– Superior analgesia in the first 72 h
– Earlier return of gut function
Postoperative analgesia
in open surgery

Thoracic epidural anesthesia (TEA)
– Low dose concentration
of local anesthetic
– Short acting opiate
– Maintained for 48 -72 h postoperative

Modification of ERAS in lap surgery ?
• RCT EDA vs Spinal vs PCA, n=91
– Lap colorectal surgery
– LOS
• EDA (3.7 d) longer than PCA and Spinal (2,8 and 2,7 d)
– Spinal
• Faster return of bowel function (vs EDA and PCA)
• Earlier tolerance of food (vs EDA)

– n=606, 2004-2009
– Primary anastomosis
– ERAS formally after 2008
– Transversus abdominis plane (TAP) or rectus sheath block
– No EDA or PCA
– KAD withdrawn in theatre
– 46% discharged within 3 days (Median LOS 4 days)
• 2 same day,
70 within 24 hrs,
• 116 within 48 hrs,
91 within 72 hrs
• Readmission rates 4 %,
– Gash KJ, Colorectal Dis, 2012
Early removal of KAD during EDA ?
• During thoracic epidural anesthesia
– Removal of KAD in the morning after surgery
• Or after removal of EDA
• RCT, N=205
• No increased need for recatheterization
• Transient increase in post-void residual volume (UL
Scanning)

Several stress-reducing interventions in ERAS
attenuate insulin resistance as single interventions:

hyperglycaemia can be avoided

Mechanical bowel preparation for elective colorectal surgery: a
meta-analysis.
Bucher P, Mermillod B, Gervaz P, Morel P.
CONCLUSIONS: 7 trialuri 1300 pt
There is no evidence to support the use of MBP
in patients undergoing elective colorectal surgery.
Available data tend to suggest that MBP could be harmful
with respect to the incidence of anastomotic leak and does
not reduce the incidence of septic complications.

Results
The response rate - 63% A (76 centers) + 30% G (385 centers).
Mechanical bowel preparation - abandoned by 2% G and 7% A surgeons.
Nasogastric decompression tubes - rarely used;
4/5 of the questioned surgeons - use intra-abdominal drains.
Half of the surgical centers - intake of clear fluids on the day of surgery.
Mobilization - in half of the centers on the day of surgery.
Epidural analgesia - three-fourths of the institutions.
Institutions which have implemented fast track rehabilitation
discharge earlier.
“Surgery and peri-operative care remains heavily based in tradition”
Practice varies substantially internationally
• survey of UK general surgeons:
• ‘there is inadequate multidisciplinary and community support’ to initiate ERAS
• ‘never heard of it’.
• survey regarding practice across European countries:
• ‘nil by mouth’
• almost abandoned in others
This is the biggest challenge
facing the wide implementation and acceptance of ERAS programs.

Current evidence supports the potential role of
multi-modal care programmes
in the promotion of early recovery from major surgical trauma.
To achieve the desired outcome targets,
all elements of the protocol must function,
a committed, multidisciplinary approach is essential
and a simple, but effective implementation and reinforcement strategies
are necessary.
