ABSTRACT Objective To describe and compare the clinical characteristics and outcomes of patients admitted to intensive care units during the first and second waves of the COVID-19 pandemic. Methods In this retrospective single-center cohort study, data were retrieved from the Epimed Monitor System; all adult patients admitted to the intensive care unit between March 4, 2020, and October 1, 2021, were included in the study. We compared the clinical characteristics and outcomes of patients admitted to the intensive care unit of a quaternary private hospital in São Paulo, Brazil, during the first (May 1, 2020, to August 31, 2020) and second (March 1, 2021, to June 30, 2021) waves of the COVID-19 pandemic. Results In total, 1,427 patients with COVID-19 were admitted to the intensive care unit during the first (421 patients) and second (1,006 patients) waves. Compared with the first wave group [median (IQR)], the second wave group was younger [57 (46-70) versus 67 (52-80) years; p

ABSTRACT Objective: To report the experience of performing bronchoscopy in patients who underwent supportive therapy with extracorporeal membrane oxygenation in whom the bronchoscopy was performed. Methods: This was a review of medical records of patients diagnosed with extracorporeal membrane oxygenation and who required diagnostic or therapeutic bronchoscopy. Records included were related to patients admitted to the intensive care unit of Hospital das Clínicas of Faculdade de Medicina of Universidade de São Paulo, between 2014 and 2020. Results: During the study, 16 bronchoscopies were performed in 8 patients admitted to the intensive care unit and who underwent supportive therapy with extracorporeal membrane oxygenation. The mean age of patients was 28.37 years. Four patients were women (50%). A total of 5 (31.25%) therapeutic bronchoscopies and 11 (68.75%) diagnostics were performed. In 5 of patients, material was collected: 4 samples of bronchoalveolar lavage, three collections of transbronchial biopsies, and 1 of endobronchial biopsies. No patient had radiological worsening or hemodynamic complications. One patient (6.25%) had transient desaturation. There was moderate bleeding after transbronchial biopsy in 1 (6.25%) procedure, which was resolved endoscopically. Conclusion: Patients undergoing extracorporeal membrane oxygenation can safely perform diagnostic or therapeutic bronchoscopy provided that they have a detailed indication. Procedures were performed by a specialized bronchoscopy team in intensive care environment and with the assistance of a qualified multidisciplinary team in membrane oxygenation therapy extracorporeal.

ABSTRACT Objective: To describe clinical characteristics, resource use, outcomes, and to identify predictors of in-hospital mortality of patients with COVID-19 admitted to the intensive care unit. Methods: Retrospective single-center cohort study conducted at a private hospital in São Paulo (SP), Brazil. All consecutive adult (≥18 years) patients admitted to the intensive care unit, between March 4, 2020 and February 28, 2021 were included in this study. Patients were categorized between survivors and non-survivors according to hospital discharge. Results: During the study period, 1,296 patients [median (interquartile range) age: 66 (53-77) years] with COVID-19 were admitted to the intensive care unit. Out of those, 170 (13.6%) died at hospital (non-survivors) and 1,078 (86.4%) were discharged (survivors). Compared to survivors, non-survivors were older [80 (70-88) versus 63 (50-74) years; p

Introduction: In Portugal, extracorporeal membrane oxygenation (ECMO) is used in pediatric patients since 2010. The aim of this study was to describe the clinical characteristics of patients, indications, complications and mortality associated with the use of ECMO during the first 10-years of experience in the Pediatric Intensive Care Unit located in Centro Hospitalar Universitário Lisboa Norte. Material and Methods: Retrospective observational cohort study of all patients supported with ECMO in a Pediatric Intensive Care Unit, from the 1st of May 2010 up to 31st December 2019. Results: Sixty-five patients were included: 37 neonatal (≤ 28 days of age) and 28 pediatric patients (> 28 days). In neonatal cases, congenital diaphragmatic hernia was the main reason for ECMO (40% of neonatal patients and 23% of total). Among pediatric patients, respiratory distress was the leading indication for ECMO (47% of total). The median length of ECMO support was 12 days. Clinical complications were more frequent than mechanical complications (65% vs 35%). Among clinical complications, access site bleeding was the most prevalent with 38% of cases. The overall patient survival was 68% at the time of discharge (65% for neonatal and 71% for pediatric cases), while the overall survival rate in Extracorporeal Life Support Organization registry was 61%. The number of ECMO runs has been increasing since 2011, even though in a non-linear way (three cases in 2010 to 11 cases in 2019). Discussion: In the first 10 years we received patients from all over the country. Despite continuous technological developments, circuitrelated complications have a significant impact. The overall survival rate in the Pediatric Intensive Care Unit was not inferior to the one reported by the Extracorporeal Life Support Organization. Conclusion: The overall survival of our Pediatric Intensive Care Unit is not inferior to one reported by other international centers. Our experience showed the efficacy of the ECMO technique in a Portuguese centre.

Objective: To characterize the transport of severely ill patients with extracorporeal respiratory or cardiovascular support. Methods: A series of 18 patients in the state of São Paulo, Brazil is described. All patients were consecutively evaluated by a multidisciplinary team at the hospital of origin. The patients were rescued, and extracorporeal membrane oxygenation support was provided on site. The patients were then transported to referral hospitals for extracorporeal membrane oxygenation support. Data were retrieved from a prospectively collected database. Results: From 2011 to 2017, 18 patients aged 29 (25 - 31) years with a SAPS 3 of 84 (68 - 92) and main primary diagnosis of leptospirosis and influenza A (H1N1) virus were transported to three referral hospitals in São Paulo. A median distance of 39 (15 - 82) km was traveled on each rescue mission during a period of 360 (308 - 431) min. A median of one (0 - 2) nurse, three (2 - 3) physicians, and one (0 - 1) physical therapist was present per rescue. Seventeen rescues were made by ambulance, and one rescue was made by helicopter. The observed complications were interruption in the energy supply to the pump in two cases (11%) and oxygen saturation < 70% in two cases. Thirteen patients (72%) survived and were discharged from the hospital. Among the nonsurvivors, there were two cases of brain death, two cases of multiple organ dysfunction syndrome, and one case of irreversible pulmonary fibrosis. Conclusions: Transportation with extracorporeal support occurred without serious complications, and the hospital survival rate was high. [ABSTRACT FROM AUTHOR]

A case of a 30 year-old man presenting with severe systemic chickenpox with refractory hypoxemia, central nervous system vasculitis and anuric renal failure is described. Ambulance transportation and support using veno-venous extracorporeal membrane oxygenation were necessary until the patient recovered. Ultimately, the potential use of extracorporeal membrane oxygenation support in low-middle income countries to manage common diseases is discussed. [ABSTRACT FROM AUTHOR]
