The use of HFNC involved a minimum reduction (5%) in admissions to the pediatric intensive care unit (PICU) in our hospital. Our main aim was to evaluate its safety and efectiveness as respiratory support for patients with bronchiolitis in a pediatric general ward. A secondary goal was to compare the admissions to PICU and the invasive mechanical ventilation (IMV) rate of patients treated with HFNC and those treated with HFNC/b-CPAP during the 2018–2019 and 2019–2020 epidemic seasons, respectively. Two prospective single-centre observational studies were performed. For the main aim, a cohort study (CS1) was carried out from 1st of November 2019 to 15th of January 2020. Inclusion criteria were children aged up to 3 months with bronchiolitis treated with b-CPAP support when HFNC failed. Epidemiological and clinical parameters were collected before and 60 min after the onset of CPAP and compared between the responder (R) and non-responders (NR) groups. NR was the group that required PICU admission. One hundred ffty-eight patients were admitted to the ward with bronchiolitis and HFNC. Fifty-seven out of one hundred ffty-eight required b-CPAP. No adverse events were observed. Thirty-two out of ffty-seven remained in the general ward (R-group), and 25/57 were admitted to PICU (NR-group). There were statistically signifcant diferences in respiratory rate (RR) and heart rate (HR) between both groups before and after the initiation of b-CPAP, but the multivariable models showed that the main diferences were observed after 60 min of therapy (lower HR, RR, BROSJOD score and FiO2 in the R-group). For the secondary aim, another cohort study (CS2) was performed comparing data from a pre-b-CPAP bronchiolitis season (1st of November 2018 to 15th January 2019) and the b-CPAP season (2019–2020). Inclusion criteria in pre-b-CPAP season were children aged up to 3 months admitted to the same general ward with moderate-severe bronchiolitis and with HFNC support. Admissions to PICU during the CPAP season were signifcantly reduced, without entailing an increase in the rate of IMV. Conclusion: The implementation of b-CPAP for patients with bronchiolitis in a pediatric ward, in whom HFNC fails, is safe and efective and results in a reduction in PICU admissions.9 p.application/pdfengcc by (c) Agüera, Marta et al., 2022http://creativecommons.org/licenses/by/4.0Urgències en pediatriaPediatriaInfeccions respiratòriesBronquisSeguretat dels pacientsPediatric emergenciesPediatricsRespiratory infectionsBronchiPatients safetyinfo:eu-repo/semantics/article7285172024-07-01info:eu-repo/semantics/openAccess
