Risk Of Mortality

Abstract Background: This retrospective study aimed to describe the efficacy, complications, and outcome of non-invasive mechanical ventilation (NIV) in critically ill children. Non-invasive mechanical ventilation (NIV) has achieved a significant breakthrough success in treating acute respiratory failure. NIV failure drastically increases the risk of mortality and morbidity. Many factors have been associated with the success of NIV. Methods. We performed a multicenter retrospective study using the demographic, prognostic, and laboratory findings of children (<18 years old) who were admitted in two pediatric intensive care units (PICUs). We compared clinical and laboratory variables in both successful and failed NIV groups. Results. Between January 2014 and April 2019, 1101 children were admitted to two PICU wards, of which, 403 were eligible for this study. In total, 138 (34.2%) patients received high-flow nasal cannula (HFNC), 138 (34.2%) patients received NIV-pressure control and 127 (31.6%) received NIV-pressure support (PSV). Patient mortality was 3.2% (13 patients) and the success rate of our study was 83.4%. Majority of our patients were provided NIV on admission (62.8%). Patients with successful NIV required fewer inotropic drugs, had shorter PICU stay duration, and a lower mortality rate during the follow up. The failure group presented a greater frequency of NIV-PSV and NIV-PCV use, along with higher NIV-associated complications. Logistic regression analysis revealed that NIV and HFNC failure increased PICU mortality by 19 times. Conclusions. HFNC and NIV are support modalities for respiratory distress in the PICU and were associated with a significant decrease in the PICU intubation rate.

IntroductionFollowing extubation from invasive mechanical ventilation, nearly one in seven critically ill adults requires reintubation. Reintubation is independently associated with increased mortality. Postextubation respiratory support (non-invasive ventilation or high-flow nasal cannula applied at the time of extubation) has been reported in small-to-moderate-sized trials to reduce reintubation rates among hypercapnic patients, high-risk patients without hypercapnia and low-risk patients without hypercapnia. It is unknown whether protocolised provision of postextubation respiratory support to every patient undergoing extubation would reduce the overall reintubation rate, compared with usual care.Methods and analysisThe Protocolized Post-Extubation Respiratory Support (PROPER) trial is a pragmatic, cluster cross-over trial being conducted between 1 October 2017 and 31 March 2019 in the medical intensive care unit of Vanderbilt University Medical Center. PROPER compares usual care versus protocolized post-extubation respiratory support (a respiratory therapist-driven protocol that advises the provision of non-invasive ventilation or high-flow nasal cannula based on patient characteristics). For the duration of the trial, the unit is divided into two clusters. One cluster receives protocolised support and the other receives usual care. Each cluster crosses over between treatment group assignments every 3 months. All adults undergoing extubation from invasive mechanical ventilation are enrolled except those who received less than 12 hours of mechanical ventilation, have ‘Do Not Intubate’ orders, or have been previously reintubated during the hospitalisation. The anticipated enrolment is approximately 630 patients. The primary outcome is reintubation within 96 hours of extubation.Ethics and disseminationThe trial was approved by the Vanderbilt Institutional Review Board. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.Trial registration numberNCT03288311.

Abstract Background Dexamethasone decreases mortality in patients with severe coronavirus disease 2019 (COVID-19) and has become the standard of care during the second wave of pandemic. Dexamethasone is an immunosuppressive treatment potentially increasing the risk of secondary hospital acquired infections in critically ill patients. We conducted an observational retrospective study in three French intensive care units (ICUs) comparing the first and second waves of pandemic to investigate the role of dexamethasone in the occurrence of ventilator-associated pneumonia (VAP) and blood stream infections (BSI). Patients admitted from March to November 2020 with a documented COVID-19 and requiring mechanical ventilation (MV) for ≥ 48 h were included. The main study outcomes were the incidence of VAP and BSI according to the use of dexamethasone. Secondary outcomes were the ventilator-free days (VFD) at day-28 and day-60, ICU and hospital length of stay and mortality. Results Among the 151 patients included, 84 received dexamethasone, all but one during the second wave. VAP occurred in 63% of patients treated with dexamethasone (DEXA+) and 57% in those not receiving dexamethasone (DEXA−) (p = 0.43). The cumulative incidence of VAP, considering death, duration of MV and late immunosuppression as competing factors was not different between groups (p = 0.59). A multivariate analysis did not identify dexamethasone as an independent risk factor for VAP occurrence. The occurrence of BSI was not different between groups (29 vs. 30%; p = 0.86). DEXA+ patients had more VFD at day-28 (9 (0–21) vs. 0 (0–11) days; p = 0.009) and a reduced ICU length of stay (20 (11–44) vs. 32 (17–46) days; p = 0.01). Mortality did not differ between groups. Conclusions In this cohort of COVID-19 patients requiring invasive MV, dexamethasone was not associated with an increased incidence of VAP or BSI. Dexamethasone might not explain the high rates of VAP and BSI observed in critically ill COVID-19 patients.

Background SARS-CoV-2 has high transmissibility through respiratory droplets and aerosol, making COVID-19 a worldwide pandemic. In its severe form, patients progress to respiratory failure. Non-invasive mechanical ventilation restrictions and early orotracheal intubation have collapsed health systems due to insufficient intensive care unit beds and mechanical ventilators. COVID-19 dedicated healthcare professionals have high infection rates. This publication describes experimental testing of the Protection and Isolation System for Patients with COVID-19 (PISP/COVID-19). Method PISP/COVID-19 is a disposable transparent polyethylene plastic that covers the patient's entire hospital bed, with its internal air aspirated by the hospital's vacuum system attached to a microparticle filter. Experiments validated PISP/COVID-19's ability to block aerosolized microparticles dissemination. Caffeine was used as a molecular marker, with leakage evaluation through sensors analysis using nuclear magnetic resonance spectroscopy. The biological marker was synthetic SARS-CoV-2 RNA, using Reverse Transcription Polymerase Chain Reaction (RT-PCR) as the detection method. Results PISP/COVID-19 was effective against molecular and biological markers environmental dispersion in simulations of non-invasive ventilation, high-flow nasal cannula oxygen and mechanical ventilation isolation. Caffeine was not detected in any of the sensors positioned at points outside the PISP/COVID-19. The ability of PISP/COVID-19 to retain virus particles and protect the surrounding environment was confirmed by detection and gradients quantification of synthetic SARS-CoV-2 RNA by RT-PCR. Conclusion PISP/COVID-19 was effective in the retention of the molecular and biological markers in all tested simulations. Considering the current pandemic, PISP/COVID-19 might increase the use of non-invasive ventilation, high-flow nasal cannula oxygen and provide additional protection to healthcare professionals.

Children in paediatric intensive care units (PICUs) are vulnerable to infections because invasive devices are frequently used during their admission. We aimed to determine the prevalence, associated factors, and prognosis of infections in our PICU. This retrospective study evaluated culture results from 477 paediatric patients who were treated in the PICU between January 2014 and March 2019. Ninety patients (18.9%) had bacterial infections, with gram-negative bacteria being the predominant infectious agents. Culture-positive patients were younger than culture-negative patients, and age was related to mortality and various clinical factors. Culture-positive bacterial infections in the PICU were associated with increased use of invasive mechanical ventilation (odds ratio(OR); 2.254), red blood cell (RBC) transfusions (OR:2.624), and inotropic drugs (OR:2.262). Carbapenem resistance was found in approximately one-third of gram-negative bacteria, and was most common in tracheal aspirate specimens and cases involving Klebsiella spp. Total parenteral nutrition was a significant risk factor (OR:5.870). Positive blood culture results were associated with poorer patient survival than other culture results. These findings indicate that infections, especially those involving carbapenem-resistant bacteria, are an important issue when treating critically ill children.
