Background: Birth asphyxia is characterized by intermittent periods of hypoxia/ischemia leading to metabolic acidosis. The use of intravenous sodium bicarbonate (IVSB) is still a matter of controversy in clinical practice. Objective: To assess the use of IVSB in birth asphyxia by attending neonatologists in European hospitals. Design/Methods: Survey using a questionnaire administered to neonatologists in Europe whose electronic addresses were provided by the national councils of neonatology of each participating country. The questionnaire consisted of a brief theoretical introduction followed by demographic questions related to the respondent’s professional qualification. This was followed by a clinical case of an asphyxiated term neonate with severe combined metabolic and respiratory acidosis and case-specific questions related to the perceived indication for administration of IVSB and use of additional therapies to address the clinical situation. Descriptive statistics and χ² analysis were performed. Results: The questionnaire was answered by 259 neonatologists from 17 countries. IVSB was believed to be indicated by 109 (42.2%) of the respondents in this clinical scenario. Results differed significantly between countries, with IVSB use varying from as high as 68% in Portugal and <5% in Scandinavian countries. However, there were no differences in the choice of other therapeutic measures. Conclusions: Although scientific evidence suggests that IVSB is not effective in asphyxiated newborns and current guidelines do not recommend its use, 42.2% of the consulted neonatologists in Europe would use it, with significant differences between but not within countries. There were no differences regarding additional measures to overcome asphyxia. Strategies to implement use of internationally accepted guidelines are needed.
