Burn injury results in a severe systemic inflammatory response which is associated with the development of acute respiratory distress syndrome (ARDS), even without associated inhalation injury. Venous-venous extracorporeal membrane oxygenation (VV-ECMO) has been implemented in various cases of ARDS to provide support and allow for protective lung ventilation strategies. We report the case of a 27-year-old man presenting with a 60% total body surface area partial thickness burn who developed refractory ARDS ...
There is wide variability in mechanical ventilation settings during ECMO in ARDS patients. Although lung rest is recommended to prevent further injury, there is no evidence to support it.
Acute lung injury is a life threatening condition often requiring mechanical ventilation. Lung-protective ventilation with tidal volumes of 6 mL/kg predicted body weight (PBW, calculated on the basis of a patient's sex and height), is part of current recommended ventilation strategy. Hence, an exact height is necessary to provide optimal mechanical ventilation. However, it is a common practice to visually estimate the body height of mechanically ventilated patients and use these estimates as a reference siz...
Acute respiratory distress syndrome (ARDS) is a condition affecting critically ill patients, characterized by pulmonary inflammation and defects in oxygenation due to either direct or indirect injury to the lungs. These guidelines will define the diagnosis and management of ARDS, particularly among combat casualties and patients in the deployed environment. The cornerstone of management of ARDS involves maintaining adequate oxygenation while avoiding further pulmonary injury through lung-protective ventilat...
Acute respiratory distress syndrome (ARDS) is a type of acute, diffuse, and inflammatory lung injury. The Berlin definition (2012) includes the following ARDS criteria: a) onset within one week of a known clinical insult, b) bilateral opacities consistent with pulmonary edema, c) respiratory failure not fully explained by cardiac failure or fluid overload, and d) ratio of partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2) of less than 300 mm Hg at a positive end expiratory pres...
Computed tomography (CT) and spirometry are the current standard methods for assessing lung anatomy and pulmonary ventilation, respectively. However, CT provides limited ventilation information and spirometry only provides global measures of lung ventilation. Thus, a method that can enable simultaneous examination of lung anatomy and ventilation is of clinical interest.
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS), characterized by overwhelming lung inflammation, are associated with high mortality. Cigarette smoke (CS) is one of the major causes of ALI/ARDS. Since high expression of prostaglandin (PG) D has been observed in CS-induced lung injury. Currently, no effective pharmacological therapies are available to treat ALI, and supportive therapies remain the mainstay of treatment. Therefore, we investigated the protective effect of CT‑133, a ne...
WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Intraoperative lung-protective ventilation has been recommended to reduce postoperative pulmonary complications after abdominal surgery. Although the protective role of a more physiologic tidal volume has been established, the added protection afforded by positive end-expiratory pressure (PEEP) remains uncertain. The authors hypothesized that a low fixed PEEP might not fit all patients and that an individually titrated PEEP during anesthesia might improve...
Different mechanical ventilation settings are known to affect lung preservation for lung transplantation. Measurement of particle flow in exhaled air may allow online assessment of the impact of ventilation before changes in the tissue can be observed. We hypothesized that by analyzing the particle flow, we could understand the impact of different ventilation parameters.
Four-dimensional computed tomography (4D-CT) ventilation is an emerging imaging modality. Functional avoidance of regions according to 4D-CT ventilation may reduce lung toxicity after radiation therapy. This study evaluated associations between 4D-CT ventilation-based dosimetric parameters and clinical outcomes.
Emergency Medical Services (EMS) professionals rely on the bag-valve-mask (BVM) to provide life-saving positive-pressure ventilation in the prehospital setting. Multiple emergency medicine and critical care studies have shown that lung-protective ventilation protocols reduce morbidity and mortality. A recent study has shown that the volumes typically delivered by EMS professionals with the adult BVM are often higher than recommended by lung-protective ventilation protocols. Our primary objective was to dete...
Acute respiratory distress syndrome (ARDS) is characterized by acute hypoxemia with diffuse alveolar damage and increased pulmonary microvascular permeability. Honokiol (HKL), the principal active ingredient of Chinese herb magnolia officinalis, protected the lung of experimental ARDS models via attenuation of inflammation and oxidative stress. However, whether HKL has protective effects against the dysfunction of pulmonary microvascular endothelial barrier and the potential mechanisms remain unclear.
Extracorporeal carbon dioxide removal (ECCO2R) devices remove CO2 directly from blood, facilitating ultraprotective ventilation or even providing an alternative to mechanical ventilation. However, ECCO2R is not widely available, whereas dialysis is available in most intensive care units (ICUs). Prior attempts to provide ECCO2R with dialysis, by removing CO2 in the form of bicarbonate, have been plagued by metabolic acidosis. We hypothesized that bicarbonate dialysis is feasible, provided the plasma strong i...
In this study, the effect of lung volume on quantitative measures of lung ventilation was investigated using MRI with hyperpolarized He and Xe. Six volunteers were imaged with hyperpolarized He at five different lung volumes (residual volume (RV), RV+1L, functional residual capacity (FRC), FRC+1L and total lung capacity (TLC)), and three were also imaged with hyperpolarized Xe. Imaging at each of the lung volumes was repeated twice on the same day with corresponding H lung anatomical images. Percentage lung...
Acute lung injury and acute respiratory distress syndrome (ALI/ARDS) refer to acute and progressive hypoxic respiratory failure caused by non-cardiogenic factors, which is a common condition occurring in critically ill patients with widespread pulmonary inflammation. Use of a single medication or target cannot treat ALI/ARDS. Mesenchymal stem cells (MSCs) and FTY720, as an analogue of sphingosine-1-phosphate (S1P), can mitigate lipopolysaccharide (LPS)-induced inflammatory lung injury. In this investigation...
Cell death is a normal phenomenon in the course of biological development, moreover, which is also a prominent feature in lung exposed to hyperoxia. Severe hypoxia occurs in ALI/ARDS patients, who generally require high concentration oxygen therapy assisted by mechanical ventilation. Nevertheless, high oxygen can cause excessive reactive oxygen species (ROS), leading to apoptosis in lung epithelial cells, which has been reported in our previous study. Herein, the correlation between increments of ROS and CC...
To explore the roles of NF-kB in the development of lung injury after one-lung ventilation.
To optimize F imaging pulse sequences for perfluoropropane (C F ) gas human lung ventilation MRI considering intrinsic in vivo relaxation parameters at both 1.5T and 3T.
Since the 2000s, there has been a trend towards decreasing tidal volumes for positive pressure ventilation during surgery. This an update of a review first published in 2015, trying to determine if lower tidal volumes are beneficial or harmful for patients.
Although therapeutic strategies for acute respiratory distress syndrome (ARDS) have achieved improvements, its mortality remains high. It has been reported that microRNAs (miRs) serve as therapeutic strategies for ARDS, while specific mechanisms of miR-494 remain poorly understood. Thus, the present study aimed to assess the effects of miR-494 on acute lung injury (ALI) in rat models of sepsis-associated ARDS and its regulatory mechanism.
Fibroproliferative repair phase of the acute respiratory distress syndrome (ARDS) is followed by a restitutio ad integrum of lung parenchyma or by an irreversible lung fibrosis and patients' death. Transforming Growth Factor-β1 (TGF-β1) is involved in collagen production and lung repair. We investigated whether alveolar TGF-β1 was associated with the presence of fibroproliferation and the outcome of ARDS patients.
The effects of different ventilation strategies during CPR on patient outcomes and lung physiology are still poorly understood. This study compares positive pressure ventilation (IPPV) to passive oxygenation (CPAP) and a novel ultra-low tidal volume ventilation (ULTVV) regimen in an experimental ventricular fibrillation animal model.
Acute respiratory distress syndrome (ARDS) is the most advanced form of acute lung injury (ALI). This is characterized by bilateral pulmonary infiltrates and severe hypoxemia. According to Berlin definition of ARDS, this is defined based on the timings, radiographic changes, edema formation, and severity on the PaO/FiO ratio. During ARDS, the loss of integrity of the epithelium causes the septic shock. The degree of epithelial injury is the major prognostic marker of ARDS. In addition to this, inflammatory ...
Acute lung injury (ALI) and/or acute respiratory distress syndrome (ARDS) are clinical conditions caused by trauma, lung infection or sepsis. ALI/ARDS is associated with massive recruitment of neutrophils into the lung with release of reactive oxygen species and excessive inflammatory response that damage alveolar tissue. Here we report the successful use of a potent chemotaxis inhibitory protein (rCHIPS) derived from Staphylococcus aureus in reducing the severity of ALI/ARDS. Treatment with rCHIPS reduces ...
