Abstract Background During the COVID-19 outbreak, healthcare providers might have avoided droplet/aerosol-generating procedures, such as non-invasive ventilation (NIV) and high-flow nasal cannula (HFNC) due to the concern of themselves being infected. We hypothesized that this change of practice could have also occurred to other non-COVID-infected patients in the Emergency Department (ED). Methods A retrospective analytic study was conducted in the ED of Siriraj Hospital, Bangkok, Thailand, including adult patients presenting with signs and symptoms of respiratory distress between 1 March and 30 April 2020 (the COVID period). A comparison group using the same inclusion criteria was retrieved from 1 March to 30 April 2019 (the pre-COVID period). The primary outcome was rate of NIV and HFNC use. The secondary outcomes were rate of intubation, failure of NIV and HFNC, complications, and mortality. Results A total of 360 and 333 patients were included during the pre-COVID and COVID periods, respectively. After adjusting for baseline differences, patients in the COVID period were less likely to receive either NIV or HFNC than the pre-COVID period (adjusted OR 0.52 [95%CI 0.29–0.92]). Overall, intubation rate was similar between the two study periods. However, patients in respiratory distress with pulmonary edema had a relatively higher intubation rate in the COVID period. There were higher failure rates of NIV and HFNC, more infectious complications, and a higher rate of mortality in the pre-COVID period. Conclusion During the COVID-19 pandemic, the overall usage of NIV and HFNC in emergency non-COVID patients decreased. Although not affecting the overall intubation rate, this change of practice could have affected some groups of patients. Therefore, treatment decisions based on a balance between the benefits to the patients and the safety of healthcare providers should be made.

Abstract Background The most common cause of respiratory failure in premature infants is respiratory distress syndrome. Historically, respiratory distress syndrome has been treated by intratracheal surfactant injection followed by mechanical ventilation. In view of the risk of pulmonary injury associated with mechanical ventilation and subsequent chronic pulmonary lung disease, less invasive treatment modalities have been suggested to reduce pulmonary complications. Methods 148 neonates (with gestational age of 28 to 34 weeks) with respiratory distress syndrome admitted to Imam Khomeini Hospital in Ahwaz in 2018 were enrolled in this clinical trial study. 74 neonates were assigned to duo positive airway pressure (NDUOPAP) group and 74 neonates to nasal continuous positive airway pressure (NCPAP) group. The primary outcome in this study was failure of N-DUOPAP and NCPAP treatments within the first 72 h after birth and secondary outcomes included treatment complications. Results there was not significant difference between DUOPAP (4.1 %) and NCPAP (8.1 %) in treatment failure at the first 72 h of birth (p = 0.494), but non-invasive ventilation time was less in the DUOPAP group (p = 0.004). There were not significant differences in the frequency of patent ductus arteriosus (PDA), pneumothorax, intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia (BPD), apnea and mortality between the two groups. Need for repeated doses of surfactant (p = 0.042) in the NDUOPAP group was significantly lower than that of the NCPAP group. The duration of oxygen therapy in the NDUOPAP group was significantly lower than that of the NCPAP group (p = 0.034). Also, the duration of hospitalization in the NDUOPAP group was shorter than that of the NCPAP group (p = 0.002). Conclusions In the present study, DUOPAP compared to NCPAP did not reduce the need for mechanical ventilation during the first 72 h of birth, but the duration of non-invasive ventilation and oxygen demand, the need for multiple doses of surfactant and length of stay in the DUOPAP group were less than those in the CPAP group.

AbstractDuring the last decades, the number of patients with long stay admissions (LSA) in PICU has increased. The purpose of this study was to identify factors associated with PICU LSA, assessing healthcare resources use and changes in the profile of these patients. A retrospective, observational, single-center study was carried out. Characteristics of LSA were compared between two periods (2006–2010 and 2011–2015). During the earlier period there were 2,118 admissions (3.9% of them LSA), whereas during the second period, there were 1,763 (5.4% of them LSA) (p = 0.025). LSA accounted for 33.7% PICU stay days during the first period and 46.7% during the second (p < 0.001). Higher use of non-invasive ventilation (80.2% vs. 37.8%, p = 0.001) and high-flow oxygen therapy (68.8% vs. 37.8%, p = 0.005) was observed in the 2011–2015 cohort, whereas the use of arterial catheter (77.1% vs. 92.6%, p = 0.005), continuous infusion of adrenaline (55.2% vs. 75.9%, p = 0.004), and hemoderivative transfusion (74% vs. 89.2%, p = 0.010) was less frequent. In the 2006–2010 cohort, hospital-acquired infections were more common (95.2% vs. 68.8%, p < 0.001) and mortality was higher (26.8% vs. 13.8%, p = 0.026). The number of long-stay PICU admissions have increased entailing an intensive use of healthcare resources. These patients have a high risk for complications and mortality.

Ventilatory support is vital for the management of severe forms of COVID-19. Non-invasive ventilation is often used in patients who do not meet criteria for intubation or when invasive ventilation is not available, especially in a pandemic when resources are limited. Despite non-invasive ventilation providing effective respiratory support for some forms of acute respiratory failure, data about its effectiveness in patients with viral-related pneumonia are inconclusive. Acute respiratory distress syndrome caused by severe acute respiratory syndrome-coronavirus 2 infection causes life-threatening respiratory failure, weakening the lung parenchyma and increasing the risk of barotrauma. Pulmonary barotrauma results from positive pressure ventilation leading to elevated transalveolar pressure, and in turn to alveolar rupture and leakage of air into the extra-alveolar tissue. This article reviews the literature regarding the use of non-invasive ventilation in patients with acute respiratory failure associated with COVID-19 and other epidemic or pandemic viral infections and the related risk of barotrauma.

Background Acute heart failure is a common presentation to Emergency Departments (ED) the world over. Amongst the most common presenting signs and symptoms is dyspnoea due to acute pulmonary oedema, a life threatening emergency that if left untreated or poorly managed. There is increasing evidence demonstrating improved outcomes following the use of vasodilators or non invasive ventilation for these patients in the emergency setting. Consequently, the potential exists that initiating these therapies in the prehospital setting will similarly improve outcomes. Methods A historical cohort study was conducted to assess the effect of a prehospital initiated treatment protocol of nitrates plus non invasive ventilation (NIV) versus regular therapy for severe cardiogenic APO on all-cause in-hospital mortality at 7 days, 30 days, and in total. Secondary outcomes included changes in EMS respiratory and haemodynamic parameters; admission status; length of stay; and emergency endotracheal intubation. Results The intervention led to an approximate 85% reduction in adjusted odds of mortality at 7 days compared to the regular therapy (AOR 0.15, 95% CI: 0.05 to 0.46, p = 0.001); approximate 80% reduction in odds of mortality at 30 days (AOR 0.19, 95% CI: 0.07 to 48, p < 0.0001); and Approximate 60% reduction in odds of total mortality (AOR 0.25, 95% CI: 0.12 to 0.56, p = 0.001). Conclusion The results of this analysis provide strong evidence of the potential synergistic benefits that can be achieved with the early implementation of a simple treatment protocol of prehospital administered nitrates and initiation of NIV for cardiogenic APO.

Abstract Respiratory failure is a serious early complication confounding the clinical effect of allogeneic stem cell transplantation and early detection may be crucial for efficient treatment. We introduced a system of intensive oxigenation monitoring in patients transplanted in our center between November 2001 and December 2003. All allogeneic transplanted patients were followed by a twice daily measurement of oxi-index (paO2/FiO2) during the transplantation period (untill day + 25). Patients that fulfilled criteria of acute lung injury (oxi-index <300) were treated by O2 application vs. non-invasive ventilation (NIV). Failure to increase oxi-index above the threshold of 300 led to referral of the patient to ICU were intensified NIV was applied and/or mechanical ventilation (MV) was initiated based on a defined scoring system. 165 patients were followed for the development of ALI. 48 (29.1%) developed oxiindices <300 (ALI). Development of ALI predicted for a significantly higher rate of ICU admissions (37.5% vs. 6.8% in non-ALI patients; p<0.001) and MV (20.8 % vs. 1.7 in non-ALI patients; p<0.001). ALI was most commonly diagnosed during the engraftment period but was at diagnosis not associated with other criteria like respiration rate, CRP and tachycardia. Since members of the pulmonary innate immune system may be associated with the development of ALI and ARDS we screened the 165 patients for the presence of alternative alleles in the Surfactant Protein B (SP-B) gene. A polymorphism at position +1580 (T/C variation) of SP-B has been previously found to be associated with the development of ARDS. Polymorphism of SP-B were not associated with the development of ALI and did not predict for the need of intensified ICU treatment. However, the rate of MV varied considerably. Nine patients with the T/T genotype (9 out of 42, 21.4%) required intubation and mechanical ventilation whereas none of the patients with C/C had to receive MV (0 out of 30; p=0.01).The data indicate that measurement of the oxiindex is an early sensitive parameter of respiratory failure in allogeneic transplantation and that severity of respiratory damage may be predicted by the T allele at the SP-B +1580 site

The COVID-19 pandemic has placed a dramatic increase in demand on healthcare providers to provide respiratory support for patients with moderate to severe symptoms. In conjunction, the pandemic has challenged existing supply-chains to meet demands for medical equipment and resources. In response to these challenges, we report our work to repurpose two existing non-invasive ventilation (NIV) systems to provide solutions for the delivery of oxygen-enriched CPAP ventilation which are inherently resource and oxygen-efficient. We consider adaptation of CPAP systems typically used for sleep apnoea, together with a new Venturi-valve design which can be readily produced through 3D printing. Our aim in both cases was to support Positive end-expiratory pressure (PEEP) of ≥10cmH2O while achieving ≥40% FiO2. This supports a crucial part in the patient pathway for COVID-19 treatment, helping to provide early respiratory support prior to invasive ventilation options in the ICU.
