Why this domain in PIVOTAL?
Anaemia is common in PICU - up to 74% of children admitted
Blood transfusions are a core process in PICU
Anaemia may be harmful by limiting oxygen delivery
Blood transfusions are commonly used to increase Hb in PICU
Transfusions may be harmful 10-17% children in PICU receive blood transfusions, more in cardiac ICU
www.icnarc.org
www.icnarc.org
Why this domain in PIVOTAL?
- Transfusion is a costly biological therapy and carries risks such as Infection, transfusion reactions, fluid overload
- Associations with increased mortality, worse respiratory function, longer ventilation, delirium
- Effects of untreated anaemia are less clear but may impact neurodevelopment

Blood transfusion thresholds – eligibility criteria: NOTE
- Patients may become eligible for the Transfusion domain at a later timepoint following randomisation into another domain(s), [Sedation and/or Fluids*]
- Must become domain eligible before the end of day 4 (calendar days) post-initial randomisation
- If so, a second randomisation will be used on confirmation of Transfusion domain-specific eligibility
- Participant list tab on ‘Sealed Envelope’ (randomisation system) – will only show patients who are still within the window to be randomised to transfusion
*Note: non-cardiac only patients for Fluid domain

www.icnarc.org
Domain timeline for randomisation
Once eligible for the Transfusion domain, children will be randomised to a:
OR
red blood cell transfusion strategy The strategy determines the transfusion threshold
i.e. a haemoglobin (Hb) level below which they should receive a blood transfusion

Randomised to restrictive or liberal strategy once domain eligible
If Hb equal to or less than higher threshold, assess if cardiovascularly stable or unstable (use Administration guide)
Two thresholds given based on stratum and disease/age
- If cardiovascularly unstable (higher)
- If cardiovascularly
stable (lower)
If cardiovascularly stable
If cardiovascularly unstable
(up to 15ml/kg allowed to avoid waste or donor exposure)
Wait until Hb equal to or less than lower threshold...

Transfuse with 10ml/kg or 1 unit packed red blood cells
(up to 15ml/kg allowed to avoid waste or donor exposure)
www.icnarc.org
www.icnarc.org
This means that it stays in place for the duration of the PICU stay and the child will only receive a blood transfusion if their Hb is less than the corresponding threshold within the strategy.
The allocated strategy commences at randomisation and continues until day 30, or PICU discharge, whichever comes first.
If a patient is re-admitted to PICU within the 30 days, treatment according to the allocated strategy will be recommenced.
Clinical team will guide the frequency of ongoing monitoring of the Hb values.

Blood transfusion thresholds domain
Click the triangles to see reasons transfusion thresholds should be suspended temporarily...
Bleeding
Moderate to severe bleeding, defined as any of the following:
- Fresh bleeding in drains ≥ 5ml/kg/hr for at least one hour
- Intra-cavity bleeding needing drainage/surgery
- The local major haemorrhage protocol is activated
Surgical procedures in operating theatre during ICU stay
Patient cannulated for ECMO
Transfusion thresholds should re-apply once bleeding stopped, return from surgery, decannulated from ECMO.
www.icnarc.org
www.icnarc.org
What do I have to do as the bedside nurse when the patient is randomised to the Transfusion Domain? (or team leader supporting less experienced nurses)
- At randomisation, the system will tell you which transfusion strategy the patient is allocated to
- Use the relevant PIVOTAL Transfusion Threshold domain administration guide and keep it at the bedside
- Check the patient’s latest Hb, compare to the administration guide to note whether they should or should not receive a blood transfusion
- If so, this is prescribed (10ml/kg) and administered following your usual procedures
- Document all transfusions/volume received using your usual PICU system
- Make sure there is a clear notice at the child’s bedside stating which Transfusion threshold they have been allocated and when they should receive a transfusion
- Hand this over at all shift changes
- Contact your senior team or research team with any questions

www.icnarc.org
Worked example (1)
Harry 10 day old 3.8kg baby admitted with possible sepsis, sedated and ventilated. He is eligible for PIVOTAL:
- Sedation domain
- Fluid domain
He would be eligible for the Transfusion domain if his Hb is less than or equal to 85g/L, now or within 4 days of randomisation into the other domains of PIVOTAL.
This is because he is
- In the non-cardiac stratum
- Does not have acute brain injury
www.icnarc.org
www.icnarc.org
Worked example (1)
Harry’s Hb is 74g/L. He is randomised to the Restrictive transfusion strategy. He is currently cardiovascularly unstable (started adrenaline 2 hours ago). BUT he WOULD NOT receive a blood transfusion.
This is because he is:
Regardless of cardiovascular instability

www.icnarc.org
Worked example (2)
Shalina, a 14-year-old girl, suffered a severe traumatic brain injury and pelvic #. She is sedated, ventilated and neuroprotected. She is eligible for PIVOTAL:
- Sedation domain
- Fluid domain
She would be eligible for the Transfusion domain if her Hb is less than or equal to 100g/L, now or within 4 days of randomisation into other PIVOTAL domains.
This is because she is
- In the non-cardiac stratum
- Has acute brain injury (ABI)
www.icnarc.org
www.icnarc.org
Worked example (2)
Shalina’s Hb is 69g/L. She is randomised to the Restrictive transfusion strategy. She is currently cardiovascularly stable. She WOULD receive a blood transfusion.
This is because she is
- In the non-cardiac stratum
- Has ABI
Regardless of cardiovascular instability

Worked example (3)
Joe, 4 year old boy admitted post cardiac surgery. He is sedated and ventilated. He is eligible for PIVOTAL:
He would be eligible for the Transfusion domain if his Hb is less than or equal to 100g/L, now or within 4 days of randomisation into other domains of PIVOTAL.
This is because he is
- In the cardiac stratum
- Is >28 days old

Cardiac
For children in the cardiac stratum, the threshold to be used depends upon clinical assessments of BOTH low cardiac output syndrome and cardiovascular stability. Low cardiac output syndrome: As diagnosed by the treating clinician. Cardiovascular instability Defined as one or more of:
(i) a fluid bolus administration in the previous 3 hours, or
(ii) vasoactive infusions (e.g., adrenaline, noradrenaline, dopamine, dobutamine, milrinone, vasopressin, angiotensin or methylene blue) started or the rate of infusion increased in the previous 3 hours, or
(iii) the most recent measured arterial lactate (within 3 hours) is greater than 3.0 mmol/L, or
(iv) the most recent upper body central venous oxygen saturations (ScvO2) (within 3 hours) is less than 60%, or
(v) the cerebral or somatic near infra-red spectroscopy (NIRS) measurement is less than 60%
Practice largely informed by single multi-centre RCT (TRIPICU)
- Nearly 20 years ago
- Low proportion of eligible patients recruited
- Several exclusions
- Recent adult evidence suggest potential neurological benefits from liberal transfusion strategy
Current UK practice variable- Median pre-transfusion Hb 78g/L in non-cardiac, 91g/L in cardiac
- Higher in cardiovascular instability
Non-cardiac
For children in the non-cardiac stratum, the threshold to be used depends upon a clinical assessment of cardiovascular stability. Cardiovascular instability
Defined as one or more of:
(i) a fluid bolus administration in the previous 3 hours, or
(ii) vasoactive infusions (e.g., adrenaline, noradrenaline, dopamine, dobutamine, milrinone, vasopressin, angiotensin or methylene blue) started or the rate of infusion increased in the previous 3 hours
