The mechanical properties of lung parenchyma are essential both in lung function and biology; consequently, experimental methods are developed to describe the mechanical behavior of lung parenchyma. During breathing and mechanical ventilation, volume change is the physiologically dominating deformation mode of lung parenchyma; nevertheless, most studies examine lung tissue in mainly isochoric tension tests. In this paper, a novel experimental method for the quantification of the compressible material behavior at high volume changes of viable lung parenchyma is proposed...

The aim of the study was to quantify nutritional losses related to pre- and postoperative fasts in critically ill intubated patients and to explore whether shorter fasts are safe and appropriate in this population. A retrospective review of mechanically ventilated adults undergoing surgery more than 24 hours after admission to a Level I trauma center over 15 months was done, which yielded 132 procedures and 81 unique patients. Ninety per cent of preoperative periods and 43 per cent of postoperative periods were affected by nonmedical barriers to feeding...

INTRODUCTION: Prostate and breast cancer screening in older patients continue to be controversial. Balancing the desire for early detection with avoidance of over-diagnosis has led to competing and contradictory guidelines for both practices. Despite similarities, it is not known how these screening practices are related at the regional level. In this study, we examined how screening PSA and mammography are related within healthcare regions, and, to better understand what may be driving these practices, whether they are associated with local intensity of care...

PURPOSE: Early mobility (EM) is being used in adult ICUs in an effort to treat and prevent intensive care unit acquired weakness (ICU-AW) and Post-Intensive Care Syndrome (PICS). Data supports children suffer from ICU-AW and PICS as well. Our objective was to create and implement an EM protocol for pediatric patients receiving invasive mechanical ventilation. METHODS: A multidisciplinary EM committee was formed to create and implement an EM protocol in a quarternary care PICU...

Non invasive ventilation (NIV) has a well established role in the treatment of acute-on-chronic respiratory failure and cardiogenic pulmonary oedema. Its role in acute hypoxaemic respiratory failure has been increasingly investigated, but its impact on the management and the outcome of the subset of patients affected by acute respiratory distress syndrome (ARDS) is still to be determined. ARDS could be a risk factor for NIV failure and in these patient delayed endotracheal intubation can lead to an increased mortality...

Relocation of large numbers of critically ill patients between hospitals is sometimes necessary and the risks associated with relocation may be high. In the setting of adherence to an interhospital intensive care unit (ICU) relocation protocol, we aimed to determine whether the interhospital relocation of all ICU patients in a single day is associated with changes in vital signs, device removal, and worse clinical outcomes. We conducted a prospective, observational, cohort study of all critically ill adults admitted to a tertiary medical center's ICUs on the day of a planned hospital relocation and exposed to interhospital ICU relocation compared with unexposed critically ill adults...

Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is used in cardiopulmonary failure patients to provide temporary assisted circulation. Usually, prolonged intubation and invasive mechanical ventilation are required in patients with ECMO support. We report on two cases of patients who had no pre-existing injuries of the affected lung, underwent VA ECMO support after open-heart surgery and received airway extubation (AE) or awake ECMO with the recovery of left ventricular ejection fraction. Atelectasis happened after AE and non-invasive positive pressure ventilation attenuated the atelectasis of one patient...

Objectives: Therapy outcomes for newly diagnosed, critically ill lung cancer patients have seldom been evaluated. This study evaluated therapy outcomes for treatment-naïve lung cancer patients in the intensive care unit (ICU). Materials and Methods: Patients were excluded if they had previously received lung cancer treatment, such as systemic chemotherapy, targeted therapy, radiotherapy, or surgical lung resection before ICU admission. The therapeutic strategies for the treatment-naïve patients were determined while they were in the ICU...

REVIEW

The discovery of surfactant was one of the most significant research events to occur in the history of neonatology. Certainly, surfactant saved lives for premature infants who were otherwise considered non-viable. However, the prevention of chronic lung disease did not progress and it became clear that a significant portion of the help surfactant provides to the premature lung is counteracted by mechanical ventilation. A dilemma exists over the priorities in premature management to intubate and administer surfactant or not to intubate and support these infants non-invasively with the use of continuous positive airway pressure...

OBJECTIVE: Dynamic tests of fluid responsiveness have been developed and investigated in clinical trials of goal-directed therapy. The impact of this approach on clinically relevant outcomes is unknown. We performed a systematic review and meta-analysis to evaluate whether fluid therapy guided by dynamic assessment of fluid responsiveness compared with standard care improves clinically relevant outcomes in adults admitted to the ICU. DATA SOURCES: Randomized controlled trials from MEDLINE, EMBASE, CENTRAL, clinicaltrials...

Severe pulmonary hemorrhage in the newborn is an infrequent, but life-threatening, event. A newborn with persistent pulmonary hypertension and a large persistent ductus arteriosus and open foramen ovale presented with hypoxemia and progressive right heart failure shortly after birth, requiring veno-arterial extracorporeal membrane oxygenation (ECMO) support. Twenty minutes after the initiation of ECMO, the patient developed severe pulmonary hemorrhage refractory to conventional treatment. As a last resort, the endotracheal tube was clamped...

Activation of CXC motif chemokine receptor 4 (CXCR4) has been reported to result in lung protective effects in various experimental models. The effects of pharmacological CXCR4 modulation on the development of acute respiratory distress syndrome (ARDS) after lung injury, however, are unknown. Thus, we studied whether blockade and activation of CXCR4 influences development of ARDS in a unilateral lung ischemia-reperfusion injury rat model. Anesthetized, mechanically ventilated animals underwent right lung ischemia (series 1: 30 min; series 2: 60 min) followed by reperfusion for 300 min...

Imminent upper airway obstruction due to life-threatening tracheal stenosis of any cause is challenging. A 77-year-old woman, with a history of temporal tracheostomy for prolonged mechanical ventilation, presented with life-threatening tracheal stenosis to the emergency department. After failed intubation with a 5.0 mm internal diameter endotracheal tube, the patient was ventilated via a tube exchanger using Ventrain. Ventrain is a manual ventilation device that, in addition to oxygen supply during inspiration, initiates expiration by actively removing gas from the lungs by suction...

BACKGROUND: In an in vitro model of mechanical ventilation with gravity-dependent filter position we observed artificially high delivered doses resulting from liquid droplet collection and precipitation of aerosolized drug. We sequentially modified the model to obtain accurate reproducible measurements of delivered dose and particle size at endotracheal tube exit. METHODS: Stepwise changes in the model included (1) altering the endotracheal tube position to a gravity-independent position, (2) adding fluid traps, (3) humidifying air near the test lung, and (4) simplifying test lung and filters...

Mechanical ventilation has the potential to increase inflammation in both healthy and injured lungs. Several animal studies have shown that variable ventilation recruits the lungs and reduces inflammation. However, it is unclear which cellular mechanisms are involved in those findings. We hypothesized that variable stretch of LPS-stimulated alveolar epithelial cells (AECs) reduces the production of pro-inflammatory cytokines compared to non-variable stretch. AECs were subjected to non-variable or variable cyclic stretch (sinusoidal pattern), with and without LPS stimulation...

BACKGROUND: Ethylene glycol intoxication causes severe metabolic acidosis and acute kidney injury. Fomepizole has become available as its antidote. Nevertheless, a prompt diagnosis is not easy because patients are often unconscious. Here we present a case of ethylene glycol intoxication who successfully recovered with prompt hemodialysis. CASE PRESENTATION: A 52-year-old Japanese male was admitted to a local hospital due to suspected food poisoning. The patient presented with nausea and vomiting, but his condition rapidly deteriorated, with worsening conscious level, respiratory distress requiring mechanical ventilation, hypotension, and severe acute kidney injury...
