Post-intensive care unit respiratory failure in older patients liberated from intensive care unit and ventilator: The predictive value of the National Early Warning Score on intensive care unit discharge.
The older adult population is continuously growing worldwide and there is increasing use of medical recourse in older patients, especially for those requiring intensive care unit (ICU) care and mechanical ventilation (MV). The present study aimed to investigate the burden and predictors of post-ICU respiratory failure in older ICU patients weaned from MV. ⋯ PIRF-14 is associated with high mortality in older ICU patients, and NEWS is a significant predictor for PIRF-14, which could be used to early identify patients at risk of post-ICU respiratory failure in the specific population.

How to facilitate the placement of a transesophageal probe in a ventilated patient?
Transesophageal probe insertion in the ventilated patients often is difficult. Different complex techniques were suggested for easier placement of the transesophageal probe. In this work, we describe a simple technique of TEE probe insertion in ventilated patients. ⋯ In the anesthetized intubated and ventilated patients, the TEE probe can be easily inserted when the patient is in the left decubital position. We suggest this algorithm in all such patients, when appropriate.

Mechanical ventilation (MV) can augment sepsis-induced organ injury. Previous studies indicate that human mesenchymal stem cells (hMSCs) have immune-modulatory effect. We hypothesize that human adipose tissue-derived stromal cells (hADSCs) could attenuate MV and sepsis-induced organ injury. ⋯ Real-time quantitative PCR was used to analyze mRNA of IL-6 and tumor necrosis factor-α (TNF-α). hADSC treatment increased survival rate of septic mice with MV. hADSCs attenuated dysfunction of the liver and kidney and decreased lung inflammation and tissue injury of the liver and lung. IL-6 level in BALF and TNF-α and IL-6 mRNA expression in the tissue of the lung, liver, and kidney were significantly reduced by hADSC treatment. MV with conventional tidal volume aggravates CLP-induced multiple organ injuries. hADSCs inhibited the compound injuries possibly through modulation of immune responses.

Point-of-care ultrasound is increasingly used at the bedside to integrate the clinical assessment of the critically ill; in particular, lung ultrasound has greatly developed in the last decade. This review describes basic lung ultrasound signs and focuses on their applications in critical care. Lung semiotics are composed of artifacts (derived by air/tissue interface) and real images (i.e., effusions and consolidations), both providing significant information to identify the main acute respiratory disorders. ⋯ Moreover, a semiquantification of lung aeration can be performed at the bedside and used in mechanically ventilated patients to guide positive end-expiratory pressure setting, assess the efficacy of treatments, monitor the evolution of the respiratory disorder, and help the weaning process. Finally, lung ultrasound can be used for early detection and management of respiratory complications under mechanical ventilation, such as pneumothorax, ventilator-associated pneumonia, atelectasis, and pleural effusions. Lung ultrasound is a useful diagnostic and monitoring tool that might in the near future become part of the basic knowledge of physicians caring for the critically ill patient.

Acid Sphingomyelinase Inhibition Attenuates Cell Death in Mechanically-Ventilated Newborn Rat Lung.
Premature infants subjected to mechanical ventilation (MV) are prone to lung injury that may result in bronchopulmonary dysplasia. MV causes epithelial cell death and halts alveolar development. The exact mechanism of MV-induced epithelial cell death is unknown. ⋯ Ventilation-induced ceramides promote autophagy-mediated cell death, and identifies SMPD1 as a potential therapeutic target for the treatment of ventilation-induced lung injury in newborns.
