Abstract Background One of the main symptoms of severe infection with the new coronavirus‑2 (SARS-CoV-2) is hypoxemic respiratory failure because of viral pneumonia with the need for mechanical ventilation. Prolonged mechanical ventilation may require a tracheostomy, but the increased risk for contamination is a matter of considerable debate. Objective Evaluation of safety and effects of surgical tracheostomy on ventilation parameters and outcome in patients with COVID-19. Study design Retrospective observational study between March 27 and May 18, 2020, in a single-center coronavirus disease-designated ICU at a tertiary care German hospital. Patients Patients with COVID-19 were treated with open surgical tracheostomy due to severe hypoxemic respiratory failure requiring mechanical ventilation. Measurements Clinical and ventilation data were obtained from medical records in a retrospective manner. Results A total of 18 patients with confirmed SARS-CoV‑2 infection and surgical tracheostomy were analyzed. The age range was 42–87 years. All patients received open tracheostomy between 2–16 days after admission. Ventilation after tracheostomy was less invasive (reduction in PEAK and positive end-expiratory pressure [PEEP]) and lung compliance increased over time after tracheostomy. Also, sedative drugs could be reduced, and patients had a reduced need of norepinephrine to maintain hemodynamic stability. Six of 18 patients died. All surgical staff were equipped with N99-masks and facial shields or with powered air-purifying respirators (PAPR). Conclusion Our data suggest that open surgical tracheostomy can be performed without severe complications in patients with COVID-19. Tracheostomy may reduce invasiveness of mechanical ventilation and the need for sedative drugs and norepinehprine. Recommendations for personal protective equipment (PPE) for surgical staff should be followed when PPE is available to avoid contamination of the personnel.

ABSTRACTBackgroundSARS-CoV-2 can cause severe respiratory failure leading to prolonged mechanical ventilation. Data are just emerging about the practice and outcomes of tracheostomy in these patients. We reviewed our experience with tracheostomies for SARS-CoV-2 at our tertiary-care, urban teaching hospital.MethodsWe reviewed the demographics, comorbidities, timing of mechanical ventilation, tracheostomy, and ICU and hospital lengths-of-stay (LOS) in SARS-CoV-2 patients who received tracheostomies. Early tracheostomy was considered <14 days of ventilation. Medians with interquartile ranges (IQR) were calculated and compared with Wilcoxon rank sum, Spearman correlation, Kruskal-Wallis, and regression modeling.ResultsFrom March 2020 to January 2021, our center had 370 patients intubated for SARS-CoV-2, and 59 (16%) had percutaneous bedside tracheostomy. Median time from intubation to tracheostomy was 19 (IQR 17 – 24) days. Demographics and comorbidities were similar between early and late tracheostomy, but early tracheostomy was associated with shorter ICU LOS and a trend towards shorter ventilation. To date, 34 (58%) of patients have been decannulated, 17 (29%) before hospital discharge; median time to decannulation was 24 (IQR 19-38) days. Decannulated patients were younger (56 vs 69 years), and in regression analysis, pneumothorax was associated was associated with lower decannulation rates (OR 0.05, 95CI 0.01 – 0.37). No providers developed symptoms or tested positive for SARS-CoV-2.ConclusionsTracheostomy is a safe and reasonable procedure for patients with prolonged SARS-CoV-2 respiratory failure. We feel that tracheostomy enhances care for SARS-CoV-2 since early tracheostomy appears associated with shorter duration of critical care, and decannulation rates appear high for survivors.

Background:  COVID-19 is associated with severe respiratory failure and high mortality in critically ill patients.2,4,5 Neurologic manifestations of the disease, including delirium and coma, may also be associated with poor clinical outcomes. Delirium is associated with prolonged mechanical ventilation and mortality.3 this study sought to describe the rates, duration, and severity of delirium in patients admitted to the ICU with COVID-19.  Methods:  A retrospective, observational study was conducted from March 1stto April 27th, 2020, at Indiana University Health Methodist and Eskenazi Health Hospitals. The delirium measurements were extracted in the first 14 days of the ICU stay, using the Richmond Agitation and Sedation Scale (RASS) and the CAM-ICU and CAM-ICU7, for those with a positive COVID-19 diagnosis. The primary outcomes were delirium rates and duration; the secondary outcome was delirium severity. Descriptive statistics and median group comparisons were done using SAS v9.4.  Results:   Of 144 patients in the study, 73.6% experienced delirium and 76.4% experienced delirium or coma. The median delirium or coma duration was 7 days (IQR: 3-10), and the median delirium duration was 5 days (IQR: 2-7). The median CAM-ICU-7 score was 6 (IQR: 2-7) signifying severe delirium. Mechanical ventilation was associated increased risk of developing delirium (OR: 22.65, 95% CL: 5.24-97.82). Mortality was also more likely in patients experiencing delirium: 26.4% compared to 15.8% in patients without delirium.   Conclusion:   Of the 144 patients included, 73.6% experienced delirium lasting on average 5 days: the median delirium score being severe. Mechanical ventilation was also associated with greater odds of developing delirium. Because Covid-19 is associated with high rates of delirium, leading to increased rates of functionality disability, more resources and attention are needed to prevent and manage delirium in patients.1      References  Brummel NE, Jackson JC, Pandharipande PP, et al.

Life Threatening

COVID-19 associated severe respiratory failure frequently requires admission to an intensive care unit, tracheal intubation, and mechanical ventilation. Among the risks of prolonged mechanical ventilation under these conditions, there is the development of tracheoesophageal fistula. We describe a case of a severe COVID-19 associated respiratory failure, who developed a tracheoesophageal fistula. We hypothesized that one of the mechanisms for tracheoesophageal fistula, along with other local and general risk factors, is the local infection due to the location of the virus itself in the tracheobronchial tree. The patient was managed successfully with surgical intervention. This case highlights the increased risk of this potentially life-threatening complication among the COVID-19 patient cohort and suggests a management strategy.

Abstract Primary Subject area Neonatal-Perinatal Medicine Background Organizational factors in neonatal intensive care units (NICUs) can increase the risk of adverse events, such as unplanned extubations (UPEs). UPE is the premature and unanticipated removal of an endotracheal tube. UPE and subsequent reintubation may increase the risk for lung injury and bronchopulmonary dysplasia (BPD) among preterm infants. Objectives First, we aimed to assess the association between daily nursing overtime and UPEs in the NICU. Second, we aimed to evaluate the association between UPE, re-intubation after UPE, and BPD in the sub-group of infants born &lt; 29 weeks’ gestational age (GA). Design/Methods We conducted a retrospective cohort study including infants admitted to a tertiary care NICU between 2016-2019. Daily nursing hours were obtained from local administrative databases. Patient data was collected from the local Canadian Neonatal Network database. Association between ratio of daily nursing overtime hours/total nursing hours (OTR) was compared between days with and without UPEs, using logistic regression analyses. Associations between UPE and BPD among infants born &lt;29 weeks requiring mechanical ventilation was evaluated in a 1:1 propensity-score matched (PSM) cohort. Infants were matched based on GA ± 2 weeks, mechanical ventilation days at time of UPE ± 5 days and SNAPII&gt;20. Results There were 108/1370 (7.8%) days with ≥ 1 UPE, for a total of 116 UPE events from 87 patients (23-42 weeks GA). Higher median OTR was observed on days with UPE compared to days without (3.3% vs. 2.5%, p=0.01). OTR was associated with higher adjusted odds of UPE (aOR 1.09, 95% CI 1.01-1.18), while other organizational variables were not (Table 1). Among ventilated infants &lt;29 weeks’ GA (n=XX), UPE rate was 31% (59), BPD rate was 42% (81) and re-intubation rate after UPE was 59% (35). In the PSM cohort of infants &lt;29 weeks, re-intubation after UPE, was associated with increased length of mechanical ventilation (aOR 16.45; CI 6.18, 26.72) as well as increased odds of BPD, when compared to infants not requiring re-intubation (aOR 4.97, 95% CI 1.54-18.27) (Table 2). Conclusion Higher nursing overtime was associated with increased UPEs in the NICU. Re-intubation was frequently required after a UPE. Among the infants born &lt; 29 weeks’ GA, UPE requiring reintubation was associated with increased total length of mechanical ventilation and increased risk of BPD. Our findings highlight the role of workforce management in improving outcomes in the NICU, through reducing the incidence of UPEs.

Drotrecogin Alpha

Hantavirus cardiopulmonary syndrome (HCPS) is associated with rapid cardiopulmonary collapse from endothelial injury, resulting in massive capillary leak, shock and severe hypoxemic respiratory failure. To date, treatment remains supportive and includes mechanical ventilation, vasopressors and extracorporeal membrane oxygenation, with mortality approaching 50%. Two HCPS survivors initially given drotrecogin alpha (activated) (DAA) for presumed bacterial septic shock are described. Vasoactive medications were required for a maximum of 52 h, whereas creatinine levels and platelet counts normalized within seven to nine days. Given the similar presentations of HCPS and bacterial septic shock, empirical DAA therapy will likely be initiated before a definitive diagnosis of HCPS is made. Further observations of DAA in HCPS seem warranted.

Introduction: The use of high-flow nasal cannulas (HFNC) in patients with hypoxemic ventilatory failure reduces the need for mechanical ventilation and does not increase mortality when intubation is promptly applied. The aim of the study is to describe the behavior of HFNC in patients who live at high altitudes, and the performance of predictors of success/failure of this strategy. Methods: Prospective multicenter cohort study, with patients aged over 18 years recruited for 12 months in 2020 to 21. All had a diagnosis of hypoxemic respiratory failure secondary to pneumonia, were admitted to intensive care units, and were receiving initial management with a high-flow nasal cannula. The variables assessed included need for intubation, mortality in ICU, and the validation of SaO2, respiratory rate (RR) and ROX index (IROX) as predictors of HFNC success / failure. Results: One hundred and six patients were recruited, with a mean age of 59 years and a success rate of 74.5%. Patients with treatment failure were more likely to be obese (BMI 27.2 vs 25.5; OR: 1.03; 95% CI: .95-1.1) and had higher severity scores at admission (APACHE II 12 vs 20; OR 1.15; 95% CI: 1.06-1.24). Respiratory rates after 12 (AUC .81 CI: .70-.92) and 18 h (AUC .85 CI: .72-0.90) of HFNC use were the best predictors of failure, performing better than those that included oxygenation. ICU mortality was higher in the failure group (6% vs 29%; OR 8.8; 95% CI:1.75-44.7). Conclusions: High-flow oxygen cannula therapy in patients with hypoxemic respiratory failure living at altitudes above 2600 m is associated with low rates of therapy failure and a reduced need for mechanical ventilation in the ICU. The geographical conditions and secondary physiological changes influence the performance of the traditionally validated predictors of therapy success. Respiratory rate <30 proved to be the best indicator of early success of the device at 12 h of use.

Abstract Background. The triggering receptor expressed on myeloid cells-1 (TREM-1) mediates fatal septic shock in murine models, but studies linking the soluble form of TREM-1 (sTREM-1) to mortality in clinical sepsis are inconclusive, and few have examined its relationship to organ dysfunction. We sought to identify associations between circulating sTREM-1 and both mortality and organ dysfunction among a broad cohort of critically ill medical, post-surgical and trauma patients. Methods. We enrolled a prospective cohort of patients who met two or more criteria for the systemic inflammatory response syndrome (SIRS) within 24 hours of intensive care unit (ICU) admission at a large academic medical center. sTREM-1 concentrations were measured at study enrollment. We used relative risk regression, adjusted for age, sex, and Charlson comorbidity index, to determine associations between sTREM-1 and the primary outcome of 28-day mortality. We also examined secondary outcomes of prevalent organ dysfunction on enrollment, and composites of persistent organ dysfunction or death at day 7. Results. Among 231 critically ill patients, non-survivors (n=19, 8%) had a higher proportion of pre-existing comorbidities, mechanical ventilation (79% vs. 44%) and shock (58% vs. 28%) compared to survivors. At study enrollment, increasing sTREM-1 was associated with a higher risk of severe acute kidney injury (AKI), shock, and acute hypoxemic respiratory failure requiring mechanical ventilation. sTREM-1 was higher among non-survivors than survivors (885 vs 336 pg/mL); each doubling of sTREM-1 concentration was associated with a 2.41-fold higher risk of 28-day mortality (95% CI 1.57, 3.72). Among 92 patients with shock on enrollment, doubling of sTREM-1 was associated with a 3.89-fold higher risk of persistent shock or death by day 7 (95% CI 1.85, 8.17). Higher sTREM-1 was also associated with a higher risk of both persistent AKI and persistent hypoxemic respiratory failure or death. Conclusions. Elevated plasma sTREM-1 is highly associated with 28-day mortality and organ dysfunction across a diverse critically ill population. These data support that early activation of the innate immune system plays a role in the development of organ dysfunction and death. Further studies should address whether modulation of the TREM-1 pathway might be beneficial in critically ill patients.

Number Of Patients

Objective and Rationale. Prone positioning of nonintubated patients has prevented intubation and mechanical ventilation in patients with respiratory failure from coronavirus disease 2019 (COVID-19). A number of patients in a recently published cohort have undergone postextubation prone positioning (PEPP) following liberation from prolonged mechanical ventilation in attempt to prevent reintubation. The objective of this study is to systematically search the literature for reports of PEPP as well as describe the feasibility and outcomes of PEPP in patients with COVID-19 respiratory failure. Design. This is a retrospective case series describing the feasibility and tolerability of postextubation prone positioning (PEPP) and its impact on physiologic parameters in a tertiary intensive care unit during the COVID-19 pandemic. Setting and Patients. This study was conducted on patients with COVID-19 respiratory failure hospitalized in a tertiary Intensive Care Unit at Surrey Memorial Hospital during the COVID-19 pandemic. Measurements and Results. We did not find prior reports of PEPP following prolonged intubation in the literature. Four patients underwent a total of 13 PEPP sessions following liberation from prolonged mechanical ventilation. Each patient underwent a median of 3 prone sessions (IQR: 2, 4.25) lasting a median of 1.5 hours (IQR: 1.2, 2.1). PEPP sessions were associated with a reduction in median oxygen requirements, patient respiratory rate, and reintubation rate. The sessions were well tolerated by patients, nursing, and the allied health team. Conclusions. The novel practice of PEPP after liberation from prolonged mechanical ventilation in patients with COVID-19 respiratory failure is feasible and well tolerated, and may be associated with favourable clinical outcomes including improvement in oxygenation and respiratory rate and a low rate of reintubation. Larger prospective studies of PEPP are warranted.
