    Abstract:
    BACKGROUND: The accurately timed extubation of ventilated ELBW preterm infants is still a problem. With different data systems the attempt has been made to more accurately predict the successful extubation of these infants. However, there do not yet exist any satisfying solutions. PATIENTS/METHODS: We retrospectively analysed 66 ELBW preterm infants who were endotracheal intubated and ventilated within 24 h postnatal. Basic data, clinical and ventilation data immediately before planned extubation and in several intervals during the following 24 h, as well as outcome variables at discharge were interpreted. RESULTS: 51 patients were successfully extubated (EE-group), 15 (22.7%) failed extubation (reintubation within 48 h after extubation, EV-group). Immediately before extubation in the EE-group there was found a significantly higher inspiratory oxygen concentration (FiO2) in comparison to the EV-group (0.25 vs. 0.3; p=0.01). After the extubation attempt the inspiratory oxygen concentration stayed lower in the EE-group, whereas in the EV-group it rose remarkably (2 h after ext.: 0.26 vs. 0.4; p<0.001). Neither of the basic data showed any significant difference. The outcome analysis indicated a longer intensive care in the EV-group and a trend towards increased BPD and ROP. CONCLUSION: The study shows that for ELBW preterm infants the inspiratory oxygen concentration is especially important to predict a successful extubation. According to our data, the inspiratory oxygen demand before and immediately after extubation establishes the essential difference between successfully extubated and reintubated infants.
