Neumotórax neonatal y desnitrogenización. Reflexiones sobre la intervención. Reporte de casos.

INTRODUCTION: The pneumothorax is consequence of the most frequent air leak in the neonatal period and its treatment is based mainly on severity of clinical manifestations. Oxygen treatment at high concentrations (Nitrogen washout) to those with mild to moderate clinical manifestations has been a therapy used to achieve its rapid resolution; However, its usefulness is controversial. CLINICAL CASES: 36-week neonates that presented spontaneous pneumothorax of 30-45%, associated with mild to moderate respiratory distress. Therefore, oxygen was indicated at high concentrations with adequate clinical response. CONCLUSIONS: The use of oxygen at high concentrations for the treatment of pneumothorax has not generated advantages by recent studies. On the contrary, there may be side effects from hyperoxia and other unfavorable clinical outcomes. In spite of this, there is likely to exist trends for use, with apparent good results. However, for recently studies, this intervention should be avoided and must follow up on the results of pneumothorax in each unit. [ABSTRACT FROM AUTHOR]
