Here you can find the pu​blication plan April 2015​​​ - and the publications from the SafeBoosC project:​

  1. The ideas behind the SafeBoosC trial and improved instrumentation (full text, open access)

  2. Testing of the performance of three commercial oximeters and a university-developed prototype (full text, open access)

  3. A pilot trial of the Oximeter-visible arm in 10 patients (full text, open access)

  4. Phase-II trial protocol publication (full text, open access)

  5. The SafeBoocS Phase II Randomised Clinical Trial:
    A Treatment Guideline for Targeted Near-Infrared-Derived Cerebral Tissue Oxygenation versus Standard Treatment in Extremely Preterm Infants (full text, open access)

  6. An in-vitro study comparing three commercial NIRS oximeters and the OxyPrem, the protype instrument of the SafeBoosC project (full text, open access)

  7. The rate of oxygenation in the minutes after birth differs as monitored by two commercial NIRS oximeters (full text, open access)

  8. The results of the SafeBoosC phase-II trial as regards the primary outcome - the burden of cerebral hypo-and hyper oxygenation . The burden was reduced to less than half (BMJ paper open access)

  9. Comparison of the prototype oximeter OxyPrem and the INVOS oximeter on the adult forarm and the term newborn head in the minutes after birth (full text, open access​)

  10. An analysis of the brain imaging done in the SafeBoosC-II trial. There was no reduction in brain injury in the experimental group compared to the control group. The largest difference between the groups were in the cerebral ultrasound data obtained during the first four days of life. At term corrected age a significant proportion of the infants did not have the planned examinations by cerebral ultrasound or by magnetic resonance imaging (full text, open access​)

  11. An analysis of the response to the alarms of the cerebral oximeter in the experimental group of the SafeBoosC-II trial. More than 50% of times, nothing was done, while 50% of interventions consisted of dialing the FiO2, i.e. using the cerebral oximeter as a supplement to the pulseoximeter. But in the remaining situations a range of clinical interventions were chosen that may well have influenced brain blood flow and hence monitoring of cerebral oxygenation may genuinely have contributed to the quality of intensive care (full text, open access)

  12. A second blood-lipid phantom study that demonstrated a quite stable relation between continuous-wave devices and a frequency-domain device when scattering is changed, but strong influence by changes in haemoglobin concentration at low levels of oxygenation. This may be important for the choice of the threshold for clinical intervention to reduce cerebral hypoxia ​(full text, open access)

  13. The reduction in the burden of cerebral hypoxia in the experimental arm of the SafeBoosC-II trial was not accompanied by a reduction in evidence of brain injury as assessed by cerebral ultrasound, aEEG, and molecular biomarkers in peripheral blood ​(full text, open access)

  14. Cerebral oximetry in preterm infants - an agenda for research with a clear clinical goal: A review of clinical research using NIRS for cerebral oximetry in preterm infants with a focus on the research required to make it clinical routine. (full text, open access​)

  15. An experiment with a refined blood-lipid phantom to compare the readings of different commercial oximeters and a revised version of the OxyPrem prototype. Value​s are provided that correspond to the 55% cerebral hypoxia threshold as defined by the INVOS 5100 with the adult sensor (full text, open access​)

  16. Uncertainty as regards the clinical value, also called equipoise, is important for the clinician that informs parents in order to obtain consent for randomizing their child for a placebo controlled clinical trial. Testing a new intervention is likely to be easier than testing an intervention that is already in clinical use in spite of lack of good evidence for its value (full text, open access)

  17. An analysis of the relation between cerebral hypoxia and cerebral hyperoxia and the early markers of brain injury. The analysis was not based on the randomization groups, and hence is observational. Cerebral hypoxia was associated with low EEG burst rate, severe brain injury, and death, but not with the molecular biomarkers of brain injury as measured in blood. Cerebral hypoxia was not clearly associated with outcomes (full text, open access)

  18. An extension of the work on standardisation of cerebral oximeters for newborn using a blood-lipid phantom (full text, open access)
