USING THE AUTOMATED FIO2- SPO2 CONTROL IN NEONATAL INTENSIVE CARE UNITS IN POLAND. A PRELIMINARY REPORT.

AIM: Analysis of the way in which a new method of implementing the automated control of oxygen therapy during respiratory support is applied in newborns with respiratory failure.

MATERIAL, METHODS AND RESULTS: The AVEA-CLiO2 ventilator with automated FiO2- SpO2 control was used in our study of 121 newborns conducted between February 2014 and January 2015 in five neonatal intensive care units. A web-based database was used to gather information entered concurrently with using the FiO2- SpO2 control system. This included demographics, clinical status, clinical indications, as well as objective and subjective experience. Among the 121 newborns 94 were preterm and 27 were near-term (33-36 hbd). The primary indication for using the system was "routine management" of FiO2 during respiratory support and it was generally initiated within the first 2 days of life. Many of the newborns were managed with the system for more than a week. The control range was usually 90%-95% SpO2, though sometimes it was lower or wider. The control range was not related to the newborn's maturity or indication for use. The perception of more "frequent and persistent" SpO2 alarms was lower when the alarms were set loosely. There were no reports of the system not working effectively.

CONCLUSIONS: We expect this first report of the routine use of automated FiO2- SpO2 control to be useful not only to other centers in Poland but also to all those adopting this important new technology. Our registry continues and we expect to have an update when we have experience with 1000 infants. Carefully controlled trials are also needed to refine the optimum use of automated FiO2- SpO2 control and to quantify its impact on neonatal outcomes.
