Objectives The aim of this study was to establish quantitative CT (qCT) parameters for pathophysiological understanding and clinical use in patients with acute respiratory distress syndrome (ARDS). The most promising parameter is introduced. Materials and methods 28 intubated patients with ARDS obtained a conventional CT scan in end-expiratory breathhold within the first 48 hours after admission to intensive care unit (ICU). Following manual segmentation, 137 volume- and lung weight-associated qCT parameters were correlated with 71 clinical parameters such as blood gases, applied ventilation pressures, pulse contour cardiac output measurements and established status and prognosis scores (SOFA, SAPS II). Results Of all examined qCT parameters, excess lung weight (ELW), i.e. the difference between a patient’s current lung weight and the virtual lung weight of a healthy person at the same height, displayed the most significant results. ELW correlated significantly with the amount of inflated lung tissue [%] (p<0.0001; r = -0.66) and was closely associated with the amount of extravascular lung water (EVLW) (p<0.0001; r = 0.72). More substantially than the oxygenation index (PaO2/FiO2) or any other clinical parameter it correlated with the patients’ mean SOFA- (p<0.0001, r = 0.69) and SAPS II-Score (p = 0.0005, r = 0.62). Patients who did not survive intensive care treatment displayed higher values of ELW in the initial CT scans. Conclusions ELW could serve as a non-invasive method to quantify the amount of pulmonary oedema. It might serve as an early radiological marker of severity in patients with ARDS.

In patients with acute respiratory distress syndrome (ARDS), prone positioning improves oxygenation but has no impact on mortality, except perhaps in those with Simplified Acute Physiology Score (SAPS) II >50. Level of evidence: 1+ (SR based on small RCTs, conducted prior to ARDSNet – subsequent change in practice)

Background At the height of the coronavirus disease 2019 (COVID-19) pandemic, Italy had the highest number of deaths in Europe; most occurred in the Lombardy region. Up to 4% of patients with COVID-19 required admission to an intensive care unit because they developed a critical illness (eg, acute respiratory distress syndrome). Numerous patients with acute respiratory distress syndrome who had been admitted to the intensive care unit required rescue therapy like prone positioning. Objectives To describe the respiratory management of and the extensive use of prone positioning in patients with COVID-19 at the intensive care unit hub in Lombardy, Italy. Methods A total of 89 patients (67% male; median age, 59 years [range, 23-80 years]) with confirmed COVID-19 who were admitted between February 23 and March 31, 2020, were enrolled in this quality improvement project. Results Endotracheal intubation was required in 86 patients (97%). Prone positioning was used as rescue therapy in 43 (48%) patients. Significantly more younger patients (age ≤ 59 years) were discharged alive (43 of 48 [90%]) than were older patients (age ≥ 60 years; 26 of 41 [63%]; P &lt; .005). Among the 43 patients treated with prone ventilation, 15 (35% [95% CI, 21%-51%]) died in the intensive care unit, of which 10 (67%; P &lt; .001) were older patients. Conclusions Prone positioning is one strategy available for treating acute respiratory distress syndrome in patients with COVID-19. During this pandemic, prone positioning can be used extensively as rescue therapy, per a specific protocol, in intensive care units.

<strong>Introduction:</strong> 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.<br /><strong>Material and Methods:</strong> 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<br />Intensive Care Unit and obits were searched for and were submitted to statistic description and analysis.<br /><strong>Results:</strong> 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 &lt; 65 years old.<br /><strong>Discussion and Conclusions:</strong> 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.

AbstractThe Acute Respiratory Distress Syndrome is still a very severe condition in intensive care patients. Prone positioning is known to improve outcome in patients with moderate to severe ARDS. Therefore proning in these patients is nowadays to be regarded as a standard of care. The risks of proning are reasonably low – if proning is done correctly. Therefore a method of proning in a step-by-step-approach is shown in this article.
