Multicenter Study Clinical Trial Observational Study
An appraisal of respiratory system compliance in mechanically ventilated covid-19 patients.
Heterogeneous respiratory system static compliance (CRS) values and levels of hypoxemia in patients with novel coronavirus disease (COVID-19) requiring mechanical ventilation have been reported in previous small-case series or studies conducted at a national level. ⋯ This multicentre report provides a comprehensive account of CRS in COVID-19 patients on MV. CRS measured within 48 h from commencement of MV has marginal predictive value for 28-day mortality, but was associated with being discharged from ICU within the same period. Trial documentation: Available at https://www.covid-critical.com/study .

ReviewDiaphragm function in acute respiratory failure and the potential role of phrenic nerve stimulation.
The aim of this review was to describe the risk factors for developing diaphragm dysfunction, discuss the monitoring techniques for diaphragm activity and function, and introduce potential strategies to incorporate diaphragm protection into conventional lung-protective mechanical ventilation strategies. ⋯ Diaphragm protection is an important consideration in optimizing ventilator management in patients with acute respiratory failure. The delicate balance between lung and diaphragm-protective goals is challenging. Phrenic nerve stimulation may be uniquely situated to achieve and balance these two commonly conflicting goals.

Observational StudyComparison of Thoracic Epidural Analgesia and Traditional Intravenous Analgesia With Respect to Postoperative Respiratory Effects in Cardiac Surgery.
Surgical stress and pain affect the respiratory condition of patients and can cause complications that affect morbidity and mortality in cardiac surgeries. The authors studied the effect of thoracic epidural analgesia (TEA) versus traditional intravenous analgesia on postoperative respiratory mechanics in cardiac surgery. ⋯ TEA provided better postoperative respiratory condition via better sedative analgesia in cardiac surgery.

Meta Analysis Comparative StudyComparative Effectiveness of Protective Ventilation Strategies for Moderate and Severe ARDS: Network Meta-Analysis.
Rationale: Choosing the best ventilation strategy for acute respiratory distress syndrome (ARDS) is complex, yet it is highly relevant to clinicians during a respiratory pandemic. Objectives: To compare the effects of low Vt, high Vt, high positive end-expiratory pressure (PEEP), prone ventilation, high-frequency oscillation, and venovenous extracorporeal membrane oxygenation (VV ECMO) on mortality in ARDS. Methods: We performed a network meta-analysis of randomized trials. ⋯ High PEEP combined with low Vt was rated intermediately (RR, 0.91 [95% CI, 0.81-1.03] vs. low Vt; low certainty; RR, 0.77 [95% CI, 0.65-0.91] vs. high Vt; moderate certainty). High Vt was rated worst (RR, 1.19 [95% CI, 1.02-1.37] vs. low Vt; moderate certainty), and we found no support for high-frequency oscillation or high Vt with prone ventilation. Conclusions: These findings suggest that combining low Vt with prone ventilation is associated with the greatest reduction in mortality for critically ill adults with moderate-to-severe ARDS.

Meta AnalysisThe predictive value of airway occlusion pressure at 100 msec (P0.1) on successful weaning from mechanical ventilation: A systematic review and meta-analysis.
The predictive value of airway occlusion pressure at 100 milliseconds (P0.1) on weaning outcome has been controversial. We performed a meta-analysis to investigate the predictive value of P0.1 on successful weaning from mechanical ventilation. ⋯ This meta-analysis suggests that P0.1 is a useful tool to predict successful weaning. To determine clinical utility, a large prospective study investigating the sensitivity and specificity of P0.1 on weaning outcomes from mechanical ventilation is warranted.
