Objectives Continuous positive airway pressure (CPAP) may be a useful treatment strategy for patients with severe COVID-19 pneumonia but its effectiveness in preventing mechanical ventilation is unknown. We aimed to evaluate the outcomes of COVID-19 patients treated with CPAP and determine predictors of CPAP response. Design This was a retrospective observational cohort study. Setting The study took place in the intensive care unit (ICU) at Royal Papworth Hospital (RPH) in Cambridge, UK. Patients We included all consecutive patients with confirmed COVID-19 pneumonia who were transferred from neighbouring hospitals between 14th March and 6th May, 2020 for consideration of ventilatory support. Intervention We instituted the use of CPAP for all patients who arrived in RPH not intubated and were not making satisfactory progress on supplemental oxygen alone. Measurements and main results Of 33 self-ventilating patients included in this study, 22 (66.7%) were male and the mean age was 54 ± 13.23 patients received CPAP. They were more hypoxaemic than those treated with oxygen alone (PaO2/FiO2 ratio; 84.3 ± 19.0 vs 170.0 ± 46.0 mmHg, p = 0.001). There was a significant improvement in PaO2/FiO2 ratio 1–2 hours after CPAP initiation (167.4 ± 49.0 from 84.3 ± 19.0 mmHg, p = 0.001). 14 (61%) patients responded to CPAP and 9 required intubation. There was no difference between these two groups in terms of the severity of baseline hypoxaemia (PaO2/FiO2 ratio; 84.5 ± 16.0 vs 83.9 ± 23.0 mmHg, p = 0.94) but CPAP responders had significantly lower C-reactive protein (CRP) (176 ± 83 vs 274 ± 63 mg/L, p = 0.007), interleukin-6 (IL-6) (30 ± 47 vs 139 ± 148 pg/mL, p = 0.037), and D-dimer (321 ± 267 vs 941 + 1990 ng/mL, p = 0.003). CT pulmonary angiogram was performed in 6 out of 9 intubated patients and demonstrated pulmonary emboli in 5 of them. All patients were discharged from ICU and there were no fatalities. Conclusions In this cohort, CPAP was an effective treatment modality to improve hypoxaemia and prevent invasive ventilation in a substantial proportion of patients with severe respiratory failure. Accepting the small sample size, we also found raised biomarkers of inflammation (CRP and IL-6) and coagulopathy (D-Dimer) to be more useful predictors of CPAP responsiveness than the severity of hypoxaemia, and could help to guide intubation decisions in this clinical setting.

Introduction: Respiratory distress is one of the commonest problem seen in neonates during admission in Neonatal Intensive Care Unit. Hyaline Membrane disease, Meconium Aspiration Syndrome, septicemia, congenital pneumonia, Transient Tachypnea of Newborn are the major causes of respiratory distress in neonates. Bubble Continuous Positive Airway Pressure is a non-invasive respiratory support delivered to a spontaneously breathing newborn to maintain lung volume during expiration. The main objective of this study was to observe the outcome of respiratory distress in neonates with Bubble Continuous Positive Airway Pressure. Methods: This was a descriptive cross-sectional study conducted at Kathmandu Medical College Teaching Hospital over six months (October 2018 – March 2019) period. All preterm, term and post term babies with respiratory distress were included. Ethical clearance was received from Institutional Review Committee of Kathmandu Medical College and statistical analysis was done with SPSS 19 version. Results: Sixty three babies with respiratory distress were included in this study with 45 (71%) male predominance. The mean birth weight receiving Bubble Continuous Positive Airway Pressure was 2661.75±84 gms and gestational age was 36.67±3.4 wks. The Bubble Continuous Positive Airway Pressure was started at 8.05±2 hr of life and duration of Bubble Continuous Positive Airway Pressure required for settling respiratory distress was 95.71±3 hrs. Out of 63 babies, improvement of respiratory distress in neonates with Bubble Continuous Positive Airway Pressure was 39 (61%) with confidence interval of (38-62) whereas 24 (39%) babies required mechanical ventilation and other modalities. Conclusions: This study concludes usefulness of Bubble Continuous Positive Airway Pressure in neonates with respiratory distress.

IntroductionIn low-resource countries, respiratory failure is associated with a high mortality risk among critically ill children. We evaluated the role of bubble continuous positive airway pressure (bCPAP) in the routine care of critically ill children in Lilongwe, Malawi.MethodsWe conducted an observational study between 26 February and 15 April 2014, in an urban paediatric unit with approximately 20 000 admissions/year (in-hospital mortality <5% approximately during this time period). Modified oxygen concentrators or oxygen cylinders provided humidified bCPAP air/oxygen flow. Children up to the age of 59 months with signs of severe respiratory dysfunction were recruited. Survival was defined as survival during the bCPAP-treatment and during a period of 48 hours following the end of the bCPAP-weaning process.Results117 children with signs of respiratory failure were included in this study and treated with bCPAP. Median age: 7 months. Malaria rapid diagnostic tests were positive in 25 (21%) cases, 15 (13%) had severe anaemia (Hb < 7.0 g/dL); 55 (47%) children had multiorgan failure (MOF); 22 (19%) children were HIV-infected/exposed. 28 (24%) were severely malnourished. Overall survival was 79/117 (68%); survival was 54/62 (87%) in children with very severe pneumonia (VSPNA) but without MOF. Among the 19 children with VSPNA (single-organ failure (SOF)) and negative HIV tests, all children survived. Survival rates were lower in children with MOF (including shock) (45%) as well as in children with severe malnutrition (36%) and proven HIV infection or exposure (45%).ConclusionDespite the limitations of this study, the good outcome of children with signs of severe respiratory dysfunction (SOF) suggests that it is feasible to use bCPAP in the hospital management of critically ill children in resource-limited settings. The role of bCPAP and other forms of non-invasive ventilatory support as a part of an improved care package for critically ill children with MOF at tertiary and district hospital level in low-resource countries needs further evaluation. Critically ill children with nutritional deficiencies and/or HIV infection/exposure need further study to determine bCPAP efficacy.
