Background: Proportions of patients dying from the coronavirus disease-19 (COVID-19) vary between different countries. We report the characteristics; clinical course and outcome of patients requiring intensive care due to COVID-19 induced acute respiratory distress syndrome (ARDS).
Methods: This is a retrospective, observational multicentre study in five German secondary or tertiary care hospitals. All patients consecutively admitted to the intensive care unit (ICU) in any of the participating hospitals between March 12 and May 4, 2020 with a COVID-19 induced ARDS were included.
Results: A total of 106 ICU patients were treated for COVID-19 induced ARDS, whereas severe ARDS was present in the majority of cases. Survival of ICU treatment was 65.0%. Median duration of ICU treatment was 11 days; median duration of mechanical ventilation was 9 days. The majority of ICU treated patients (75.5%) did not receive any antiviral or anti-inflammatory therapies. Venovenous (vv) ECMO was utilized in 16.3%. ICU triage with population-level decision making was not necessary at any time. Univariate analysis associated older age, diabetes mellitus or a higher SOFA score on admission with non-survival during ICU stay.
Conclusions: A high level of care adhering to standard ARDS treatments lead to a good outcome in critically ill COVID-19 patients.
Background:
Regional ventilation of the lung can be visualized by pulmonary electrical impedance tomography (EIT). The aim of this study was to examine the post‐operative redistribution of regional ventilation after lung surgery dependent on the side of surgery and its association with forced vital capacity.
Methods:
In this prospective, observational cohort study 13 patients undergoing right and 13 patients undergoing left‐sided open or video‐thoracoscopic procedures have been investigated. Pre‐operative measurements with EIT and spirometry were compared with data obtained 3 days post‐operation. The center of ventilation (COV) within a 32 × 32 pixel matrix was calculated from EIT data. The transverse axis coordinate of COV, COVx (left/right), was modified to COVx′ (ipsilateral/contralateral). Thus, COVx′ shows a negative change if ventilation shifts contralateral independent of the side of surgery. This enabled testing with two‐way ANOVA for repeated measurements (side, time).
Results:
The perioperative shift of COVx′ was dependent on the side of surgery (P = .007). Ventilation shifted away from the side of surgery after the right‐sided surgery (COVx′‐1.97 pixel matrix points, P < .001), but not after the left‐sided surgery (COVx′‐0.61, P = .425). The forced vital capacity (%predicted) decreased from 94 (83‐109)% (median [quartiles]; [left‐sided]) and 89 (80‐97)% (right‐sided surgery) to 61 (59‐66)% and 62 (40‐72)% (P < .05), respectively. The perioperative changes in forced vital capacity (%predicted) were weakly associated with the shift of COVx′.
Conclusion:
Only after right‐sided lung surgery, EIT showed reduced ventilation on the side of surgery while vital capacity was markedly reduced in both groups.
