The nurse is the cornerstone of nutrition delivery (Nestle Health Science sponsored session)

Nurse driven metabolic care

(Mette Berger)

Pts with lower cumulative protein and energy deficits are 3x more likely to go home

ICU is a changeful environment – multiple factors preventing pts from being fed to prescribed goals, but the MAIN problem is often getting EN prescribed / re-started

Nurse-driven protocols (e.g. insulin infusion, catheter infection prevention, resuscitation etc) have a track record of working well!

–> Can Nutrition be nurse-driven, independent of doctors?

  • focus on glycaemic control
  • initiation / resumption of feeding
  • tube placement / control
  • monitoring of delivery

Clear protocols listing roles with describing their responsibilities

Metabolism and nutritional needs vary through the phases of critical illness / during rehabilitation

Nutritional Risk Score (NRS) to identify pts at risk of nutrition-related complications

Glycaemic control

  • demonstrable improvement in tight glucose control when transferred to the care of nurses
  • nurse immediately available to assess and respond to BMs

Initiation of Feeding

  • gastric residues may prevent feeding first 48 hrs post-op
  • can check using ultrasound
  • try pro kinetics during this time

Tube placement

  • tube checking protocols

Monitoring delivery

  • ESPEN guidelines suggest progressively increasing feeding; aggressive early feeding risks hurting sick gut

  • do NOT aim to cover prescribed feeding goals in the first week
  • nurse is well-positioned to detect signs of pt tolerating / not tolerating feed
  • Beware absent stools – Encourage emollients and fibres in feed upon initiation of feeding – this should not cause significant diarrhoea

 

**Metabolic rationale for starting slow:

Endogenous glucose production is stopped by eating (in healthy people) – this mechanism is lost in critical illness, and therefore there is continuous endogenous glucose production of 200-300g glucose / day = 800kcal even if EN is commenced

–> therefore, starting with a full feed will result in overfeeding

 

A nursing perspective on nutrition

(Beatrice Jenni-Moser, M-M Jeitziner)

Nutrition has a significant impact on a pt’s ability to respond to medical / nursing treatment

Large variation in nursing practices around nutrition (availability of nutritional guidelines, knowledge and leadership)

Nutrition is often prioritised lower than other care needs

** pt’s relatives are often concerned about having ‘enough to eat’

New paradigm of rehabilitation: Start early, not at the end of medical treatment

–> the same should apply to nutrition – need an MDT approach

 

Quality project

  • Setting: Interdisciplinary ICU / 37 beds
  • Approx 4000pts / year
  • Length of stay: 2.4days (mean); 8% of pts stay 7days or more

Aim: Overview of nutrition, diarrhoea and constipation

Method: Chart reviews

Sample: (Neurological disease 40%)

2018 – 97 pts, mean age 61.4 (16-90)

2017 – 93 pts, mean age 60.2 (21-94)

— Protocol designed around existing guidelines for patients and also potentially difficult pts

  • EN as the standard approach, early EN within 48 hrs
  • Continuous rather than bolus EN
  • Contraindication to oral, EN –> PN should start within 3-7 days
  • Early and progressive PN is better than starvation
  • After 3 days, caloric delivery can be increased up to 80-100%

Nutritional Assessment: In-depth evaluation of objective and subjective data related to an individual’s food and nutrient intake, lifestyle, medical history

Combine with Frailty scale in every pt for a baseline frailty score (not just in the older pts / long stay)

Take home message: ICU nurses are in a unique situation to take an active role in promoting the best nutritional outcomes to the pts

  • interprofessional nutrition education
  • nutritional screening and assessment
  • using standardised guidelines / protocols
  • evaluating nutrition support

32nd Annual Congress – Berlin

This year we are returning to Berlin, a cosmopolitan city of with a turbulent and fascinating history. Berlin is home to world-renowned universities, orchestras, museums, and entertainment venues and is well-known for its festivals, diverse architecture, nightlife, contemporary arts and a very high quality of living. A continental hub for air and rail traffic, Berlin is easy to reach and the congress venue, the Berlin CityCube, reflects the city well with its multi-functional and edgy design.

We can guarantee that LIVES 2019 will not disappoint and hope you will be joining us in Berlin for a memorable congress.

 

New Technology in Ventilation 25th September 2017 #LIVES2017

In respiratory failure, there is regional variability in oxygenation (and perfusion)- imaging can be used to monitor this. Point of care ultrasound for instance ncbi.nlm.nih.gov/pmc/articles/P…

Electrical Impedance tomography can monitor regional changes as well ncbi.nlm.nih.gov/pubmed/25843526

Oesophageal manometry can help us monitor transpulmonary pressure nejm.org/doi/full/10.10… – however is only used in about 1% of ARDS patients according to the LUNG-SAFE study jamanetwork.com/journals/jama/…

Respiratory muscle functioning can be done using the NAVA device journals.sagepub.com/doi/pdf/10.117… – this may end up being key to keeping intrapleural driving pressure low (Amato)

Mechanical power can be roughly calculated at the bedside as a product of driving pressure and respiratory rate- this may become our key targeted variable in future (Amato)ncbi.nlm.nih.gov/m/pubmed/27620…

However both driving pressure and mechanical power remain static measures of lung mechanics. In future we’ll need dynamic bedside tools.

Ventilator dissynchrony remains a problem and contributes to mortality…. ncbi.nlm.nih.gov/pubmed/25693449

 

And of course there’s ECMO. Some patients still require ventilation while on ECMO and the reasons for this will vary- for some it will be gas exchange, for others it will be muscular (Camporotta).

There remain several unanswered questions in the ECMO population- how to wean, who needs (and doesn’t need) mechanical ventilation… hopefully answers will come.

 

The future may well be closed-loop ventilation, such as that seen with the Hamilton ventilators in their ASV mode.
