ABSTRACT

Introduction: High altitude decreases the ambient oxygen pressure requiring higher inspiratory oxygen fractions (FiO2). High-flow nasal cannulas (HFNC) are a strategy that improves the supply of oxygen without disrupting comfort. Objective: To describe the use of HFNC in patients admitted to the Neonatal Intensive Care Unit (NICU) of a center at an altitude of 2,600 a.m.s.m. Material and methods: A descriptive study was carried out in patients admitted to a NICU in Bogotá, Colombia. Demographic characteristics, clinical diagnoses, vital signs, flows, FiO2 and the degree of respiratory distress by the Silverman-Andersen scale. Time of use, hospital stay and frequency of failure or adverse events were determined. Results: 139 patients were enrolled. Median respiratory distress score was low (2) with only one case of severe respiratory distress. On average, a high FiO2 (50%) was used. In 24 cases the therapy failed (17.2%) and no adverse events were reported. Conclusion: The use of HFNC at high altitude allows the use of more FiO2 in patients with low respiratory distress scores and thus decreases the use of more invasive methods.
