Current opinion in critical care

To describe the management principles that have not been verified or tested but nonetheless successfully guide the logic of everyday practice at the bedside. ⋯ The practitioner of intensive care often has no choice but to make difficult decisions and to select a course of treatment that remains unguided by specific, scenario-specific evidence from observational studies and clinical trials. Experience gathered over many prior encounters combined with solid physiologic understanding helps to develop guiding principles and unproven rules of management that serve well in confronting complex, ever changing problems of acute illness. Although some element of trial and error is unavoidable, careful monitoring, short loop feedback, and mid-course corrections render many logic-driven and experience-driven decisions relatively safe to implement and often effective in an uncertain, high-stakes environment.

ReviewExtracorporeal membrane oxygenation for respiratory failure in adults.
This article reviews case series and trials that evaluated extracorporeal membrane oxygenation (ECMO) for respiratory failure and describes patient and circuit management in the modern era of ECMO support. ⋯ The latest generation of ECMO systems is more biocompatible, better performing and longer lasting. Although recent studies suggested that veno-venous ECMO might improve the outcomes of patients with ARDS, indications for ECMO use remain uncertain. Future trials of ECMO for severe ARDS should strictly control for standard-of-care mechanical ventilation strategies in the control group and early transportation on ECMO for patients in the intervention arm.

ReviewOrgan crosstalk during acute lung injury, acute respiratory distress syndrome, and mechanical ventilation.
Multiple organ failure is the main cause of morbidity and mortality in acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) patients. Moreover, survivors of both ALI and ARDS often show significant neurocognitive decline at discharge. These data suggest a deleterious organ crosstalk between lungs and distal organs. This article reviews the recent literature concerning the role of this organ crosstalk during ALI, ARDS, and mechanical ventilation, especially focusing on brain-lung communication. ⋯ Organ crosstalk is an emerging area of research in lung disease in critically ill patients. The findings of these studies are clinically relevant and show the importance of an integrative approach in the management of critical patients. However, further studies are necessary to understand the complex interactions concurring in these pathologies.

ReviewImaging in acute lung injury and acute respiratory distress syndrome.
The review focuses on recent achievements obtained by means of imaging techniques in clinical and experimental studies on acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). ⋯ Major improvements were recently obtained in imaging structure and several functions of the lungs, with the potential of positively impacting the clinical practice.

ReviewNoninvasive ventilation for the immunocompromised patient: always appropriate?
Over the last few decades, the survival rate in critically ill immunocompromised patients has substantially improved, mainly because of advances in oncohematological treatments and management of organ dysfunctions in the ICU. As a result, the number of patients admitted to the ICU has rapidly grown. Immunocompromised patients in whom acute respiratory failure (ARF) develops often require mechanical ventilatory support. In these patients, noninvasive ventilation (NIV) has the potential of avoiding endotracheal intubation and its complications. This review will discuss the recent findings on the role of NIV in immunocompromised patients with ARF. ⋯ Use of NIV may not be appropriate for all immunocompromised patients. However, current evidence supports the use of NIV as the first-line approach for managing mild/moderate ARF in selected patients with immunosuppression of various origin.
