Why me?
• Geriatrician working in hip fracture care
• Successful intervention technique in this difficult
group
• Currently involved in RCT for preoperative
carbohydrate loading in emergency surgery for
NOF

Goals• Haematinics and anaemia management preop
• Look at recent recommendations for nutrition in periop period and evidence behind them
• AKA – How it might help you and yours
• Practicalities.
• How we try to make it work in the real world.

What I will not be covering
• Preoperative weight loss in obesity
• Details of parenteral nutrition
• Specific patient type recommendations
![Page 5: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/5.jpg)
Haematinics and anaemia
• Iron
• B12
• Folate
• (Also needs Vit C, B1 and B6)
• Identification of cause is important
![Page 6: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/6.jpg)
Risks of perioperative anaemia
Risks of anaemia
◦ Mortality and morbidity increases
Risks of transfusion
◦ “standard” – haemolytic, TRALI,etc
◦ Mortality, length of stay

Iron replacement• Oral replacement.–Has a place but slow and side effects limit
• Infusion– Effective
– Some risks
• +/- EPO– Potential side effects hypertension, thrombosis

Process
• Bloods reviewed at time of waitlisting
• Liaise with GP if bloods not done
• Nurse lead
• PART of the story – also need to manage intraoperative blood loss, anticoagulation, transfusion protocols…..

Protein / calorie deficits
• Increased morbidity and mortality
• Increased length of stay
• Less likely to be discharged home
• Inflammatory response – catabolism –glycogen, fat, protein with subsequent muscle loss

Severe nutritional risk Wt loss >10-15% within 6 months
BMI <18.5 kg/m2
SGA Grade C or NRS >5

ESPEN 2017 guidelines• Integration of nutrition into overall management
• Avoid long periods of fasting
• Re-establishment of oral feeding as early as possible
• Start nutritional therapy early – as soon as risk becomes apparent
• Metabolic control
• ↓ factors that exacerbate catabolism or reduce GI function
• ↓ time on paralytic agents for ventilator Mx
• Early mobilisation

6. Assess nutritional status before and after
major surgery
Think about thiamine and multivitamins for
malnourished
![Page 19: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/19.jpg)

3. In general oral nutritional intake shall be
continued after surgery without interuption
4. Adapt oral intake to individual and surgery
5. Oral intake (including clear fluids) should be
initiated within hours of surgery for most
![Page 26: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/26.jpg)
Nutritional therapy
7. Nutritional therapy indicated in patient with malnutrition and those at nutritional risk.
- Also if anticipated unable to eat for more than 5 days or not above 50% recommended for 7 days
- Enteral route where possible
8. If req. cannot be met by oral route combination of enteral and parenteral nutrition

13. Peri- or postop immunonutrients should
be given in malnourished patients
undergoing major cancer surgery (B)
- No clear evidence for these vs
standard nutritional supps exclusively (O)

Immunonutrition?• Enteral diet with additional arginine,
glutamine, omega 3, and/or RNA
• Theorised to alter immune function and cytokine production
• Several negative studies in well nourished patients
• Care in sepsis (REDOXX study)
![Page 29: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/29.jpg)

Enteral immunonutrition vs high protein
◦ No change in rates of infection
◦ No change in length of stay
◦ Increased 6 month mortality in “medical” pts
◦ No benefits, some potential risks

What have we done about it? Multidisciplinary, multimodal, systematic nutrition care
◦ Blanket dietician review
◦ “medicalisation”of nutrition – recognising malnutrition as a
disease and nutrition as the clinical intervention
◦ Coordinated multidisciplinary approach and delegation of care
◦ Enhanced food services system
◦ Improving nutrition knowledge and awareness
Team involvement in identifying issues
◦ Pragmatic action research
![Page 34: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/34.jpg)
Elective considerations
Identification of those at risk
Selection of screening tools
Timely reviews
Think about thiamine supplementation
also
![Page 35: Dr Alisa Crouch Geriatrician The Prince Charles …...Goals •Haematinics and anaemia management preop •Look at recent recommendations for nutrition in periop period and evidence](https://reader030.fdocuments.us/reader030/viewer/2022040818/5e6276deea1a2f6942721e83/html5/thumbnails/35.jpg)
Food for thought… Screen for malnutrition using a validated tool as
soon as possible
Feed at risk patients early – go hard with protein
Starve your patients sparingly
Avoid restrictive diets including delayed or staged diet upgrades.
When the gut works, use it (but there is a place for PN)
Use funky nutrition to generate interest but don’t forget the basics.
