To study the effect of setting positive end-expiratory pressure (PEEP) in an individualized manner (based on highest static compliance) compared to setting PEEP according to FiO2 upon mortality at 28 and 90 days, in patients with different severity acute respiratory distress syndrome (ARDS). ⋯ In patients with severe ARDS, individualized PEEP selection based on the best static compliance was associated to lower mortality at 90 days, with an increase in organ dysfunction-free days at 28 and 90 days.

Correlation between transition percentage of minute volume (TMV%) and outcome of patients with acute respiratory failure.
We have previously shown in patients receiving adaptive support ventilation (ASV) that there existed a Transition %MinVol (TMV%) where the patient's work of breathing began to reduce. In this study, we tested the hypothesis that higher TMV% would be associated with poorer outcome in patients with acute respiratory failure. ⋯ An increase, or lack of decrease, of TMV% from Day 1 to Day 2 was associated with higher risk of in-hospital death.

Comment LetterEffect of ulinastatin combined with thymosin alpha1 on sepsis: A systematic review and meta-analysis of Chinese and Indian patients.
To assess the effects of urinary trypsin inhibitor (UTI) ulinastatin combined with thymosin alpha1 (Tα1) on sepsis. ⋯ Treatment of UTI+Tα1 can suppress the production of proinflammatory cytokines, decrease the APACHE II score, shorten the duration of mechanical ventilation and vasopressor use, and improve the 28-day survival rate.

Implementation of a respiratory rehabilitation protocol: weaning from the ventilator and tracheostomy in difficult-to-wean patients with spinal cord injury.
Following repeated weaning failures in acute care services, spinal cord injury (SCI) patients who require prolonged mechanical ventilation and tracheostomy are discharged to their homes or skilled nursing facilities, with a portable mechanical ventilator (MV) and/or tracheostomy tube (TT) with excess risk of complications, high cost and low quality of life. We hypothesized that many difficult-to-wean patients with cervical SCI can be successfully managed in a rehabilitation clinic. The aim of our study was to develop a respiratory rehabilitation, MV weaning and TT decannulation protocol and to evaluate the effectiveness of this protocol in tetraplegic patients. ⋯ A multifaceted, multidisciplinary respiratory management program can change the process of care used for difficult-to-wean patients with SCI. Implications for rehabilitation Findings from this study indicate the significance of a multidimensional evaluation of any reversible factors for prolonged MV- and/or TT-dependent SCI patients. Thus, rehabilitation specialists should take this into consideration and should provide the appropriate amount of time to these patients. The proposed protocol of respiratory rehabilitation for MV- and/or TT-dependent SCI patients shows promising results in terms of changing the care used for these patients. Successful implementation of a respiratory rehabilitation and weaning protocol is dependent on careful planning and detailed communication between the rehabilitation specialist and intensivist during the respiratory rehabilitation process. Because many of the so-called difficult- or impossible-to-wean patients were successfully weaned from MV and TT in the PMR clinic, the need for such an outlet for countries without specialized centers is supported.

Bronchoscopy during mechanical ventilation of patients' lungs significantly affects ventilation because of partial obstruction of the tracheal tube, and may thus be omitted in the most severely ill patients. It has not previously been possible to reduce the external diameter of the bronchoscope without reducing the diameter of the suction channel, thus reducing the suctioning capacity of the device. We believed that a better-designed bronchoscope could improve the safety of bronchoscopy in patients whose lungs were ventilated. ⋯ We next evaluated the consequences of bronchoscopy when using the prototype on minute ventilation and intrathoracic pressures during mechanical ventilation: firstly, in vitro using a breathing simulator; and secondly, in vivo using a porcine model of pulmonary ventilation. The insertion of adult bronchoscopes into the tracheal tube immediately impaired the protective ventilation strategy employed, whereas the prototype preserved it. For the first time, we have developed an innovative flexible bronchoscope designed for bronchoscopy during invasive mechanical ventilation, that both preserved the protective ventilation strategy, and enabled efficient suction flow.
