Abstract Background Acute respiratory failure develops in infants with bronchiolitis and Community acquired pneumonia (CAP) because of hypoxemia, due to mismatch between ventilation and perfusion. Nasal continuous airway pressure (nCPAP) and high-flow nasal cannula (HFNC) improve the work of breathing and oxygenation .High flow nasal cannula (HFNC), also called heated humidified high flow nasal cannula (HHHFNC), is a new non-invasive ventilation therapy that seems to be well tolerated in infants with hypoxemic respiratory failure. Aim To compare the effectiveness and the outcome of Heated Humidified High Flow Nasal Cannula (HFNC) versus Nasal Continuous Positive Airway Pressure (NCPAP), as a primary mode of respiratory support, in patients with respiratory failure due to pneumonia or bronchiolitis at PICU regarding demographic data, length of admission, increasing of positive pressure and need of intubation. Patients and Methods observational study was conducted on 40 patients with acute respiratory failure due to either bronchiolitis or community acquired pneumonia (CAP), admitted to Paediatric ICU, Children Hospital, Ain Shams University, in the time period between February 2018 to July 2019. The patients, aged between 1 month to 5 years, were subjected to detailed clinical history and examination.All patients received continuous monitoring of electrocardiograph ,pulse oximetry and respiratory rate .The patients were treated either with (HFNC) Humidified high flow nasal cannula or continuous positive airway pressure (CPAP). Studied groups were compared regarding demographic data, increasing in respiratory support ,need of intubation, fate and length of admission during PICU stay. Results HFNC was as efficient as CPAP in lowering RR(respiratory rate) and HR(heart rate) in infants with bronchiolitis and community acquired pneumonia. Thus HFNC group was as significant as NCPAP group in treatment of bronchiolitis and CAP regarding length of admission ,increasing of positive pressure and need of iintubation in PICU . Conclusion This study concluded that HFNC is as efficient as nCPAP for initial respiratory support in young infants, hospitalized in a PICU for moderate to severe acute respiratory failure.

Background: Non-invasive respiratory support including high-flow nasal oxygen (HFNO), and continuous positive airway pressure (CPAP) have been used to provide therapy in selected SARS-CoV-2 patients with acute respiratory failure (ARF). The value of the ROX index, a validated benchmark for outcomes in HFNO is unknown in CPAP. Objective: Can the ROX, a validated benchmark in HFNO be used for measuring treatment outcomes of CPAP in SARS-COV-2 ARF? Study Design and Methods: A non-randomised prospective protocol driven observational non-intensive care unit study in 130 SARS-COV-2 patients with ARF treated with non-invasive therapy from March 2020 to January 2021. The primary end point was failure of therapy (death or escalation). Secondary outcomes included time to failure including invasive mechanical ventilation (IMV) or death, the effect of escalation to CPAP from HFNO and the utility of ROX in ARF. Results: HFNO was better than CPAP in treating SARS-COV-2 ARF: 17/35 (48.5%) with successful HFNO therapy versus 24/95 (25.2%) with CPAP. The ROX index was more sensitive to outcomes with CPAP compared to HFNO and distinguished treatment failure early at 1, 4, 6, 12, and 24 hours with the highest sensitivity at 24 hours (ROX-24h). The AUC for the ROX-24h was 0.77 for HFNO (P<0.0001), and 0.84 for CPAP (P<0.0001). The ROX-24h cut-points predicted failure with HFNO when < 3.9 (PPV 71%, NPV 75%) and CPAP < 4.3 (PPV 75%, NPV 91%). For success, ROX-24h cut-points of 7.6 for HFNO (PPV 85%, NPV 48%) and 6.1 for CPAP (PPV 88%, NPV 62%) were observed. Escalation from HFNO to CPAP was mostly not successful. Conclusion: ARF in SARS-COV-2 can be successfully managed by non-invasive support. The ROX index, validated for HFNO, provides a timely, low resource measure for both HFNO and CPAP avoiding delayed intubation.

Invasive Verfahren

ZusammenfassungIn der Corona-Pandemie werden zunehmend nicht-invasive Verfahren zur Behandlung des akuten hypoxämischen Versagens bei COVID-19 eingesetzt. Hier stehen mit der HFOT (high-flow oxygen therapy), CPAP (continuous positive airway pressure) und der NIV (non-invasive ventilation) unterschiedliche Verfahren zur Verfügung, die das Ziel einer Intubationsvermeidung verfolgen. Der aktuelle Übersichtsartikel fasst die heterogene Studienlage zusammen. Wesentlich ist die Erkenntnis, dass diese nicht-invasiven Verfahren durchaus auch bei einem schweren, akuten hypoxämischen Versagen erfolgreich sein können und damit die Intubation wie auch Tubus-assoziierte Komplikationen vermeiden können. Demgegenüber bleibt aber ebenso zu betonen, dass die prolongierte unterstützte Spontanatmung ebenfalls zu Komplikationen führt und dass demzufolge insbesondere ein spätes NIV-Versagen mit erheblich verschlechterter Prognose einhergeht, was vor dem Hintergrund weiterhin hoher NIV-Versagensraten in Deutschland bedeutsam ist. Der aktuelle Artikel verweist schließlich auch auf einen Parallelartikel in dieser Ausgabe, der die medial in der Öffentlichkeit in Deutschland geführte Debatte zu diesem Thema aufgreift und deren inhaltliche Fragwürdigkeit, aber auch die negativen Auswirkungen auf die Gesellschaft und die Fachwelt adressiert. Gleichzeitig wird die Bedeutung von regelmäßig zu überarbeitenden Leitlinien untermauert.
