NCT03092297

Brief Summary

The purpose of this study is whether the mitochondrial oxygenation tension (mitoPO2) is a feasible and reliable tool in ICU patients with anaemia undergoing red cell transfusion to ultimately personalize blood transfusion decisions in the ICU.

Outcome Measures

Primary Outcomes (1)

  • Variability of mitoPO2

    Variability of mitoPO2 before and after red cell transfusion. This will be compared to traditional parameters used to measure oxygenation and oxygen balance.

    Variability of mitoPO2 will be assessed during 8 predefined moments (within a timeframe of 24 hours) in the study

Secondary Outcomes (5)

  • Organ damage

    Value of mitoPO2 in predicting (ischemic) organ damage will be assessed during 8 predefined moments (within a timeframe of 24 hours) in the study

  • Microcirculation

    Association of the mitoPO2 with the microcirculation will be assessed during 2 predefined moments (before transfusion and 24 hours after transfusion) in the study

  • Length of stay

    Length of stay will be assessed during the 3 months follow-up time

  • Mortality

    Mortality will be assessed during the 3 months follow-up time

  • Adverse events

    Association of the mitoPO2 with adverse events will be assessed during 8 predefined moments (within a timeframe of 24 hours) in the study

Study Arms (1)

ICU patients with anaemia

At admission to the ICU all patients, or their legal representatives, expected to stay at the ICU for longer than 24 hours will be asked to participate in the study and will be asked informed consent. ICU patients with anaemia in whom a central venous catheter is already in place and in whom a red cell transfusion is planned, will be included in the study.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

All adult patients admitted to the intensive care unit with a Hb below 6.3 mmol/l, with a central venous catheter in situ, who are planned to undergo a transfusion of red blood cells

You may qualify if:

  • adult patient admitted to the ICU
  • Hb below 6.3 mmol/l (10 g/dl)
  • central venous catheter in situ
  • red cell transfusion planned

You may not qualify if:

  • adults without a legal representative to ask for informed consent
  • patients less than 18 years old
  • pregnant or breast feeding women
  • patients in need of emergency red cell transfusion e.g. bleeding
  • not having a central venous catheter in situ
  • porphyria and or known photodermatosis
  • patients with an expected ICU stay \<24 hours
  • patients with hypersensitivity to the active substance or to the plaster material of ALA

Biospecimen

Retention: SAMPLES WITHOUT DNA

Blood samples will be taken for measurement of: troponin, creatinine kinase, creatinine, hemoglobin, lactate, central venous oxygen saturation, arterial saturation, arterial oxygen tension, and venous oxygen tension. Remaining plasma will be frozen and stored for further evaulation
