Recent studies reported that children on mechanical ventilation who were managed with an analgosedation approach and standardized extubation readiness testing experienced better outcomes, including decreased delirium and invasive mechanical ventilation duration. ⋯ A multidisciplinary, bundled benzodiazepine-sparing analgosedation and extubation readiness testing approach resulted in a reduction in mechanical ventilation duration and benzodiazepine exposure without impacting key balancing measures. External validity needs to be evaluated in similar centers and consensus on best practices developed.

High-Flow Nasal Cannula Therapy in Patients With COVID-19: Predictive Response Factors.
COVID-19 pneumonia has been responsible for many ICU patients' admissions with hypoxemic respiratory failure, and oxygen therapy is one of the pillars of its treatment. The current pandemic scenario has limited the availability of ICU beds and access to invasive ventilation equipment. High-flow nasal cannula (HFNC) can reduce the need for orotracheal intubation compared with conventional oxygen therapy, providing better results than noninvasive respiratory support. However, HFNC use has been controversial due to concerns about the benefits and risks of aerosol dispersion. In this context, we evaluated the performance of the HFNC therapy in patients with COVID-19 and investigated factors that can predict favorable responses. ⋯ In 6 months, 128 subjects were included and the success rate of HFNC therapy was 53%. Logistic regression analysis showed that the Charlson comorbidity score, need for oxygen flow, [Formula: see text], and breathing frequency predicted therapy failure. The mortality rate increased among the non-responders versus the responders (47% vs 3%), 48% of failure occurred in the first 24 h of the HFNC therapy. A ROX (respiratory frequency - oxygenation) index > 4.98 in 6 h and > 4.53 in 24 h predicted success of the HFNC therapy with an area under the curve of 0.7, and a ROX index < 3.47 predicted failure with 88% of specificity. CONCLUSIONS: HFNC in the subjects with COVID-19 was associated with reduced mortality and improved oxygenation in the subjects with respiratory distress. Close monitoring of specific parameters defines eligible patients and rapidly identifies those in need of invasive ventilatory support.
