RESUMEN
Education, as a macro field of social and political issues, is the path to the realization of the possibilities for changes in the macro structures of society. The objective of the research was to understand the challenges in the performance of the coordinators of public pandemic (Covid-19). as a technique, exploratory research. questionnaire. pointed out that the pedagogical coordinators develop actions that contribute to the monitoring of student learning and the work of teachers, with a view to alleviating the challenges posed in education in times of pandemic. schools in the municipal network of Maceio pedagogical in times of The methodology was based on the qualitative approach and, In all, 44 pedagogical The data collection instrument was the online coordinators participated. The main results
RESUMEN
OBJECTIVE: We examined weather a protocol for fraction of inspired oxygen (FiO2) adjustment can reduce hyperoxemia and excess oxygen use in COVID-19 patients mechanically ventilated. DESIGN: Prospective cohort study. SETTING: Two intensive care units (ICUs) dedicated to COVID-19 patients in Brazil. PATIENTS: Consecutive patients with COVID-19 mechanically ventilated. INTERVENTIONS: One ICU followed a FiO2 adjustment protocol based on SpO2 (conservative-oxygen ICU) and the other, which did not follow the protocol, constituted the control ICU. MAIN VARIABLES OF INTEREST: Prevalence of hyperoxemia (PaO2>100mmHg) on day 1, sustained hyperoxemia (present on days 1 and 2), and excess oxygen use (FiO2>0.6 in patients with hyperoxemia) were compared between the two ICUs. RESULTS: Eighty two patients from the conservative-oxygen ICU and 145 from the control ICU were included. The conservative-oxygen ICU presented lower prevalence of hyperoxemia on day 1 (40.2% vs. 75.9%, p<0.001) and of sustained hyperoxemia (12.2% vs. 49.6%, p<0.001). Excess oxygen use was less frequent in the conservative-oxygen ICU on day 1 (18.3% vs. 52.4%, p<0.001). Being admitted in the control ICU was independently associated with hyperoxemia and excess oxygen use. Multivariable analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FiO2 use and adverse clinical outcomes. CONCLUSIONS: Following FiO2 protocol was associated with lower hyperoxemia and less excess oxygen use. Although those results were not associated with better clinical outcomes, adopting FiO2 protocol may be useful in a scenario of depleted oxygen resources, as was seen during the COVID-19 pandemic.
RESUMEN
OBJECTIVE: To compare adherence to protective mechanical ventilation (MV) parameters in patients with acute respiratory distress syndrome (ARDS) caused by COVID-19 with patients with ARDS from other etiologies. DESIGN: Multiple prospective cohort study. SETTING: Two Brazilian cohorts of ARDS patients were evaluated. One with COVID-19 patients admitted to two Brazilian intensive care units (ICUs) in 2020 and 2021 (C-ARDS, n=282), the other with ARDS-patients from other etiologies admitted to 37 Brazilian ICUs in 2016 (NC-ARDS, n=120). PATIENTS: ARDS patients under MV. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Adherence to protective MV (tidal volume ≤8mL/kg PBW; plateau pressure ≤30cmH2O; and driving pressure ≤15cmH2O), adherence to each individual component of the protective MV, and the association between protective MV and mortality. RESULTS: Adherence to protective MV was higher in C-ARDS than in NC-ARDS patients (65.8% vs. 50.0%, p=0.005), mainly due to a higher adherence to driving pressure ≤15cmH2O (75.0% vs. 62.4%, p=0.02). Multivariable logistic regression showed that the C-ARDS cohort was independently associated with adherence to protective MV. Among the components of the protective MV, only limiting driving pressure was independently associated with lower ICU mortality. CONCLUSIONS: Higher adherence to protective MV in patients with C-ARDS was secondary to higher adherence to limiting driving pressure. Additionally, lower driving pressure was independently associated with lower ICU mortality, which suggests that limiting exposure to driving pressure may improve survival in these patients.
