It was reported that carbon monoxide-releasing molecule-3 (CORM-3) administration immediately after hemorrhagic shock and resuscitation (HSR) ameliorates the HSR-induced acute lung injury (ALI); however, the specific mechanism of the protective effects against HSR-induced ALI remains unclear. ⋯ We identified the protective effects of CORM-3 against HSR-induced ALI. The mechanism might be related to the inhibition of p38MAPK signaling pathway in lung macrophages.

Association Between the Oxygen Consumption: Lactate Ratio and Survival in Critically Ill Patients With Sepsis.
Mitochondrial dysfunction leading to impairment of oxygen extraction, referred to as cytopathic hypoxia, contributes to morbidity in sepsis. Oxygen consumption (VO2) may be a useful measure of the severity of cytopathic hypoxia. We monitored VO2 and carbon dioxide production (VCO2) in septic patients and investigated the association with hospital survival. ⋯ The VO2:lactate ratio was significantly higher in survivors, while there was no association between median VO2 alone and survival. There was a significant difference in change in VCO2 over time between survivors and non-survivors.

Extracorporeal life support (ECLS) is a support modality for patients with severe acute respiratory distress syndrome (ARDS) who have failed conventional treatments including low tidal volume ventilation, prone positioning, and neuromuscular blockade. In addition, ECLS can be used for hemodynamic support for patients with cardiogenic shock or following cardiac arrest. ⋯ We then describe how these principles are applied in the management of the novel coronavirus disease 2019 pandemic. Indications, predictors, procedural considerations, and post-cannulation management strategies are discussed.
