Safety and outcomes of percutaneous tracheostomy in coronavirus disease 2019 pneumonitis patients requiring prolonged mechanical ventilation

Abstract Objectives Tracheostomy for coronavirus disease 2019 pneumonitis patients requiring prolonged invasive mechanical ventilation remains a matter of debate. This study analysed the timing and outcomes of percutaneous tracheostomy, and reports our experience of a dedicated ENT–anaesthetics department led tracheostomy team. Method A prospective single-centre observational study was conducted of patients undergoing tracheostomy, who had been diagnosed with coronavirus disease 2019 pneumonitis, between 21st March and 20th May 2020. Results Eighty-one patients underwent tracheostomy after a median (interquartile range) of 16 (13–20) days of invasive mechanical ventilation. Median follow-up duration was 32 (23–40) days. Of patients, 86.7 per cent were successfully liberated from invasive mechanical ventilation in a median (interquartile range) of 12 (7–16) days. Moreover, 68.7 per cent were subsequently discharged from hospital. On univariate analysis, there was no difference in outcomes between early (before day 14) and late (day 14 or later) tracheostomy. The mortality rate was 8.6 per cent and no deaths were tracheostomy related. Conclusion Outcomes appear favourable when patients are carefully selected. Percutaneous tracheostomy performed via a multidisciplinary approach, with appropriate training, was safe and optimised healthcare resource utilisation.

Abstract Background: We studied the safety of percutaneous dilatational tracheostomy (PCDT) in severe acute respiratory syndrome novel coronavirus 2 (SARS-nCoV2). Patients & Methods: From 01 March 20 to 30 November 2020, 1635 required hospital admission of which 145 (9%) required intensive (ICU) care. The primary outcomes are mortality and secondary outcomes were duration of invasive mechanical ventilation (IMV), length of stay (LOS) in ICU and hospital, & days required for decannulation.Results: Out of the 145 (9%), 107 (73.7%) were males (mean 61.4 years, median body mass index (BMI) of 28.2 kg/m2 ), 38 (26.2%) were females (mean 58.10 years, median BMI of 31.2 kg/m2). In the cohort of 80 (55.17%) requiring IMV, 19 (23.7%) died within 72 hours and were not included in the study, 37 (group “NT”) and 24 (group “T”) had a median duration of ventilation of 9 d (IQR, 6-11) and 12 d (IQR, 11-17.25) respectively. Patients in group “T” underwent PCDT based on clinical criteria (fraction of inspired oxygen (FiO2 ) of ≤ 50% with positive end-expiratory pressure (PEEP) of ≤ 10 cms of H2O with stable hemodynamics), 16 (66.7%) had survived. The reverse transcription-polymerase chain reaction (RT-PCR) does not need to be negative, and none of the health care workers (HCW’s) were infected. The Cox-hazard ratio [HR] is 0.19, 95% Confidence interval [CI] (0.09, 0.41) with a P-value of <0.001, 83 (57.2%) were discharged with a mortality of 42.8%. Conclusions: PCDT is safe and effective in patients anticipated in need of prolonged mechanical ventilation.

Purpose To describe the trajectory of respiratory failure in COVID-19 and explore factors associated with risk of invasive mechanical ventilation (IMV). Materials and methods A retrospective, observational cohort study of 112 inpatient adults diagnosed with COVID-19 between March 12 and April 16, 2020. Data were manually extracted from electronic medical records. Multivariable and Univariable regression were used to evaluate association between baseline characteristics, initial serum markers and the outcome of IMV. Results Our cohort had median age of 61 (IQR 45–74) and was 66% male. In-hospital mortality was 6% (7/112). ICU mortality was 12.8% (6/47), and 18% (5/28) for those requiring IMV. Obesity (OR 5.82, CI 1.74–19.48), former (OR 8.06, CI 1.51–43.06) and current smoking status (OR 10.33, CI 1.43–74.67) were associated with IMV after adjusting for age, sex, and high prevalence comorbidities by multivariable analysis. Initial absolute lymphocyte count (OR 0.33, CI 0.11–0.96), procalcitonin (OR 1.27, CI 1.02–1.57), IL-6 (OR 1.17, CI 1.03–1.33), ferritin (OR 1.05, CI 1.005–1.11), LDH (OR 1.57, 95% CI 1.13–2.17) and CRP (OR 1.13, CI 1.06–1.21), were associated with IMV by univariate analysis. Conclusions Obesity, smoking history, and elevated inflammatory markers were associated with increased need for IMV in patients with COVID-19.

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.

Abstract Background: Some patients with severe coronavirus disease (COVID-19) who present with fibrosis on computed tomography (CT) require prolonged mechanical ventilation (PMV). Lung ultrasound (LUS), a rapid, bedside test, has been reported to have findings consistent with those of CT. Thus, this study aimed to assess whether serial LUS scores could predict PMV or successful extubation in severe COVID-19 patients.Methods: LUS was performed for 20 consecutive severe COVID-19 patients at three time points: admission (day 1), after 48 h (day 3), and seventh-day follow-up (day 7). We compared the LUS score with the results of chest X-rays and laboratory tests at three time points. Moreover, we assessed LUS score to determine the inter-rater reliability (IRR) of the results among examiners.Results: While there were no significant differences in mortality in each PMV and successful extubation groups, there were significant differences in LUS scores on day 3 and day 7; XP score on day 7; and P/F ratio on day 7 in the PMV group (p<0.05). There were significant differences in LUS scores on days 3 and 7, C-reactive protein (CRP) levels on day 7, and P/F ratio on day 7 in the successful extubation group (p<0.05). The areas under the curves (AUCs) of LUS score on days 3 and 7, XP score on day 7, and P/F ratio were 0.88, 0.98, 0.77, and 0.80, respectively in the PMV group; and the AUCs of LUS score on days 3 and 7, CRP levels on day 7, and P/F ratio 0.79, 0.90, 0.82, and 0.79, respectively, in the successful extubation group. Variations in serial LUS scores exhibited significant differences between the groups. The serial LUS score on day 7 was higher than that on day 1 in the PMV group but lower in the successful extubation group (p<0.05). However, there was slight IRR agreement in the LUS score changes on days 1 to 7 (κ= 0.15 [95% CI: 0-0.31]). Conclusions: The serial LUS score of severe COVID-19 patients could predicted PMV and successful extubation. To overcome IRR disagreement, the automatic ultrasound judgement, such as deep learning, would be needed.

Introduction: There are no established guidelines for selecting patients for early tracheostomy. The aim was to determine the factors that could predict the possibility of intubation longer than 7 days in critically ill adult patients. Methods: This is cohort study made at a general intensive care unit. Patients who required at least 48 hours of mechanical ventilation were included. Data on the clinical and physiologic features were collected for every intubated patient on the third day. Uni- and multivariate statistical analyses were conducted to determine the variables associated with extubation. Results: 163 (62%) were male, and the median age was 59±17 years. Almost one-third (36%) of patients required mechanical ventilation longer than 7 days. The variables strongly associated with prolonged mechanical ventilation were: age (HR 0.97 (95% CI 0.96-0.99); diagnosis of surgical emergency in a patient with a medical condition (HR 3.68 (95% CI 1.62-8.35), diagnosis of surgical condition-non emergency (HR 8.17 (95% CI 2.12-31.3); diagnosis of non-surgical-medical condition (HR 5.26 (95% CI 1.85-14.9); APACHE II (HR 0.91 (95% CI 0.85-0.97) and SAPS II score (HR 1.04 (95% CI 1.00-1.09) The area under ROC curve used for prediction was 0.52. 16% of patients were extubated after day 8 of intubation. Conclusions: It was not possible to predict early extubation in critically ill adult patients with invasive mechanical ventilation with common clinical scales used at the ICU. However, the probability of successfully weaning patients from mechanical ventilation without a tracheostomy is low after the eighth day of intubation.

Introduction: Acute Respiratory Distress Syndrome has a significant incidence and mortality at Intensive Care Units. Therefore, more studies are necessary in order to develop new effective therapeutic strategies. The authors have proposed themselves to characterize Acute Respiratory Distress Syndrome patients admitted to an Intensive Care Unit for 2 years. Material and Methods: This was an observational retrospective study of the patients filling the Acute Respiratory Distress Syndrome criteria from the American-European Consensus Conference on ARDS, being excluded those non invasively ventilated. Demographic data, Acute Respiratory Distress Syndrome etiology, comorbidities, Gravity Indices, PaO2/FiO2, ventilator modalities and programmation, pulmonary compliance, days of invasive mechanical ventilation, corticosteroids use, rescue therapies, complications, days at Intensive Care Unit and obits were searched for and were submitted to statistic description and analysis. Results: A 40 patients sample was obtained, with a median age of 72.5 years (interquartile range = 22) and a female:male ratio of ≈1:1.86. Fifty five percent of the Acute Respiratory Distress Syndrome cases had pulmonary etiology. The mean minimal PaO2/FiO2 was 88mmHg (CI 95%: 78.5–97.6). The mean maximal applied PEEP was 12.4 cmH2O (Standard Deviation 4.12) and the mean maximal used tidal volume was 8.2 mL/ Kg ideal body weight (CI 95%: 7.7–8.6). The median invasive mechanical ventilation days was 10. Forty seven and one half percent of the patients had been administered corticosteroids and 52.5% had been submitted to recruitment maneuvers. The most frequent complication was Ventilator Associated Pneumonia (20%). The median Intensive Care Unit stay was 10.7 days (interquartile range 10.85). The fatality rate was 60%. The probability of the favorable outcome ‘non-death in Intensive Care Unit’ was 4.4x superior for patients who were administered corticosteroids and 11x superior for patients < 65 years old. Discussion and Conclusions: Acute Respiratory Distress Syndrome is associated with long hospitalization and significant mortality. New prospective studies will be necessary to endorse the potential benefit of steroid therapy and to identify the subgroups of patients that warrant its use.

Background. COVID-19 is a worldwide pandemic, with many patients requiring prolonged mechanical ventilation. Tracheostomy can shorten ICU length of stay and help weaning. Aims/Objectives. To describe the long-term evolution of the critically patient with COVID-19 and the need for invasive mechanical ventilation and orotracheal intubation (OTI), with or without tracheostomy. Material and Methods. A prospective study was performed including all patients admitted to the ICU due to COVID-19 from 10th March to 30th April 2020. Epidemiological data, performing a tracheostomy or not, mean time of invasive mechanical ventilation until tracheotomy, mean time from tracheotomy to weaning, and final outcome after one month of minimum follow-up were recorded. The Otolaryngology team was tested for COVID-19 before and after the procedures. Results. Out of a total of 1612 hospital admissions for COVID-19, only 5.8% (93 patients) required ICU admission and IOT. Twenty-seven patients (29%) underwent a tracheostomy. After three months, within the group of tracheotomized patients, 29.6% died and 48.15% were extubated in a mean time of 28.53 days. In the nontracheostomized patients, the mortality was 42.4%. Conclusions. Tracheostomy is a safe procedure for COVID-19 and helps weaning of prolonged OTI. Mortality after tracheostomy was less common than in nontracheostomized patients.

Abstract Background: Marginal zone Lymphoma (MZL) is the third most abundant lymphoma and it is subclassified into 3 entities: splenic, nodal and extranodal mucosa associated lymphoid tissue (MALT). Positron emission tomography (PET) using 18F fluorodeoxyglucose (FDG) with computed tomography (CT) is increasingly used for staging and response assessment of FDG avid lymphomas, such as diffuse large B cell lymphoma and Hodgkin lymphoma. The role of PET/CT in lymphomas with variable FDG avidity, such as MZL, is still under active research. Aims: The purpose of this study was to evaluate PET/CT as a diagnostic and prognostic tool in patients with MZL. Methods: A retrospective cohort study of patients with newly diagnosed MZL, treated with immunotherapy, chemotherapy regimen, surgery or eradication between 2008 and 2016 in a single tertiary center. Patients who did not undergo pre-treatment PET/CT (P-PET/CT) were excluded. Patients were identified through the hospital's computerized database. Demographic, clinical and laboratory data were collected from patients' files until the latest follow-up available and for at least 12 months after completion of treatment administration. P-PET/CT, interim (I-PET/CT) and end-of-treatment PET/CT (E-PET/CT) studies were centrally reviewed by a nuclear specialist and reported using 3 methods of evaluation: visual assessment, maximal SUV reported and Deauville 5-point score (DS) evaluation (DS only for I-PET/CT and E-PET/CT). PET/CT was interpreted as positive if any of the three evaluation methods was positive. The primary outcome was to evaluate the prognostic role of P-PET/CT, I-PET/CT and E-PET/CT on progression free survival (PFS) and overall survival (OS). Survival curve was calculated using the Kaplan-Meier method, and Cox regression. Models adjusted for age, sex, and stage were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) was used for the association between PET/CT positivity, PFS and OS. Results: Data of 196 patients with MZL were identified. 86 patients were excluded due to absence of P-PET/CT. Thus, 110 patients were included in this analysis. The most frequent histological type of MZL was MALT (51%). Median patients' age was 67 years (range: 18-93). The median follow-up period was 63 months (range: 3-278). 54/110 (73%) presented with bone marrow involvement and 100/110 (91%) had extranodal involvement. MZL transformed to an aggressive lymphoma in 3% of the patients. The median OS and PFS for the whole cohort were 63 months (interquartile range: 39-85) and 60 months (interquartile range: 37-76), respectively. 77/110 (71.3%) patients had positive P-PET/CT. Among 19 patients that had I-PET/CT, eight studies were positive and 11 negative. 63/110 patients underwent E-PET/CT: 12 studies were positive and 51 negative. P-PET/CT and I-PET/CT were not predictive of PFS or OS. Sub-group analysis of the different types of MZL did not show such a correlation as well. When adjusted for age, sex and stage, positive E-PET/CT was associated with reduced PFS with a hazard ratio (HR) of 4.16 (CI 1.55-11.2, p=0.005) (Figure 1). Conversely, positive E-PET/CT did not correlate with OS maybe due to the low death rate (3 patients). In a univariate analysis, beta 2 microglobulin was prognostic for PFS with and adjusted HR of 1.44 (CI 1.08-1.94, p-0.014). Conclusions: Our study shows that above 70% of MZL are FDG avid. P-PET/CT and I-PET/CT were not predictive of PFS; However, E- PET/CT was predictive of PFS with an adjusted HR of 4.2. Figure 1: The association between E-PET/CT in PFS Disclosures No relevant conflicts of interest to declare.
