Filter by:The aim of the this study is to assess the short term physiological effects of 3 ventilation strategies for adult patients with ARDS admitted to intensive care unit. Two of those strategies are based on electrical impedance tomography (EIT) monitoring.
The concept of Ventilator-induced Lung Injury Vortex (VILI vortex) has recently been proposed as a progressive lung injury mechanism in which the alveolar stress/strain increases as the ventilable lung "shrinks" (1). This positive feedback inexorably leads to the acceleration of lung damage, with potentially irreversible results. Little is known about the clinical aspects of this condition. Understanding its behavior could contribute to changing its potential devastating impact. The objective of this study is to evaluate the incidence of VILI vortex in patients with acute respiratory syndrome (ARDS) secondary to COVID-19, to establish a connection between this phenomenon and mortality, and to identify the factors that have an impact on its development.
TRALI was defined as "acute noncardiogenic pulmonary edema typically occurs ≤ 6 hours following transfusion of plasma-containing blood products, such as packed red blood cells, fresh frozen plasma, platelets, or cryoprecipitate." In critically ill patients, TRALI remains the leading cause of transfusion-related fatalities and is accompanied by a very significant morbidity and mortality. Survival in such patients is as low as 53% compared with 83% in acute lung injury (ALI) controls. The incidence of TRALi is likely underreported. In densely populated developing countries, incidence has not decreased due to lack of male-only strategy for plasma donation. TRALI is associated with systemic inflammation characterized by low anti-inflammatory cytokine as interleukin (IL)-10, increased pro-inflammatory cytokine as IL-8. Regulation of inflammation should include avoidance of overproduction of inflammatory mediators. So, it can be dampened not only by increasing IL-10 but also by decreasing IL-1β release. C-reactive protein (CRP) is an acute phase protein which is up-regulated during infections and inflammation. CRP was recently identified as a novel first hit in TRALI. Till now, there is no established treatment for TRALI beyond supportive care and monitoring. Recently, potential therapies have been reviewed, and it was concluded that the most promising therapeutic strategies are IL-10 therapy, downregulation of CRP levels, targeting reactive oxygen species (ROS) or blocking IL-8 receptors. So, antioxidants (such as high dose vitamins), were recommended for future studies as potentially effective treatment. Vitamin C hypovitaminosis is observed in 70% of critically ill despite receiving recommended daily doses. The aim of this study is to investigate the role of intravenous vitamin C (ascorbic acid) as a targeted therapy for transfusion related acute lung injury (TRALI) in critically ill patients in terms of IL-8, IL-10, CRP, SOD, malondialdehyde (MDA), vasopressor use, duration of mechanical ventilation, ICU length of stay, 7-days mortality and 28-days mortality.
During surgery high concentrations of supplementary oxygen are routinely administrated. However, there is increasing evidence of potential harm with liberal oxygen therapy. The hypothesis of the present study is that oxygen therapy adjusted to a normal arterial oxygen target is feasible and will attenuate the side effects of supplementary oxygen therapy. The study design is a before-and-after study in which 25 patients will follow the standard regime with high concentrations of oxygen therapy and 25 patients will be treated with oxygen to achieve a normal value of arterial oxygenation.
This study is a prospective observer blinded, central randomization controlled, multi-center clinical trial to assess the relationship between intraoperative FiO2 and postoperative pulmonary complications with lung injury.
Hematopoietic stem cell transplant (HSCT) is an effective but toxic therapy and pulmonary morbidity affects as many as 25% of children receiving transplant. Early pulmonary injury includes diffuse alveolar hemorrhage (DAH), thrombotic microangiopathy (TMA) interstitial pneumonitis (IPS) and infection, while later, bronchiolitis obliterans is a complication of chronic GVHD associated with severe morbidity and mortality. Improved diagnosis and treatment of pulmonary complications are urgently needed as survival after HSCT improves, and as HSCT is increasingly used for non-malignant disorders such as sickle cell disease. Currently, there are large and important gaps in the investigator's knowledge regarding incidence, etiology and optimal treatment of pulmonary complications. Moreover, young children unable to perform spirometry are often diagnosed late, and strategies for monitoring therapeutic response are limited. This is a prospective multi-institutional cohort study in pediatric patients undergoing allogeneic (alloHSCT) or autologous hematopoietic stem cell transplantation (autoHSCT). Assembly of a large prospective uniformly screened cohort of children receiving HSCT, together with collection of biological samples, will be an effective strategy to identify mechanisms of lung injury, test novel diagnostic strategies for earlier diagnosis, and novel treatments to reduce morbidity and mortality from lung injury after transplant.
This study will evaluate the use of N-acetyl cysteine in post-reperfusion pulmonary injury in patients with chronic thromboembolic pulmonary hypertension undergoing pulmonary balloon angioplasty and pulmonary endarterectomy. Half of the patients will receive N-acetyl cysteine and the other placebo.
Previous clinical trials in adults with acute respiratory distress syndrome (ARDS) have demonstrated that ventilator management choices can improve Intensive Care Unit (ICU) mortality and shorten time on mechanical ventilation. This study seeks to scale an established Clinical Decision Support (CDS) tool to facilitate dissemination and implementation of evidence-based research in mechanical ventilation of infants and children with pediatric ARDS (PARDS). This will be accomplished by using CDS tools developed and deployed in Children's Hospital Los Angeles (CHLA) which are based on the best available pediatric evidence, and are currently being used in an NHLBI funded single center randomized controlled trial (NCT03266016, PI: Khemani). Without CDS, there is significant variability in ventilator management of PARDS patients both between and within Pediatric ICUs (PICUs), but clinicians are willing to accept CDS recommendations. The CDS tool will be deployed in multiple PICUs, targeting enrollment of up to 180 children with PARDS. Study hypotheses: 1. The CDS tool in will be implementable in nearly all participating sites 2. There will be > 80% compliance with CDS recommendations and 3. The investigators can implement automatic data capture and entry in many of the ICUs Once feasibility of this CDS tool is demonstrated, a multi-center validation study will be designed, which seeks to determine whether the CDS can result in a significant reduction in length of mechanical ventilation (LMV).
Ventilator-induced lung injury is a common complication. The latest and most noticeable theory of its pathogenesis is called 'ergotrauma' by Gattinoni in 2016. The theory uses ventilator-imposed 'energy' or 'power' to encompass several known forms of injury-inducing factors such as pressure,volume, flow, rate, etc. However, to quantify power imposed by ventilator is no easy task in clinical practice. So, Gattinoni proposed a mathematical formula for easy power calculation. However, Gattinoni did not compare the difference between various etiologies of acute lung injury. We will enroll 100 patients (50 with acute respiratory distress syndrome and 50 with normal lung). The ventilator-imposed power at various tidal volume (6, 8, 10 ml/Kg) and positive end-expiratory pressure (5, 10 cmH2O) will be calculated by the formula. The area enclosed by hysteresis of pressure-volume curve, and hence the work it implies, will be measured as a standard. Our study will aim to compare the formula in different patient groups and in Taiwanese people.
The aim of this questionnaire-based survey is to evaluate the routine use of individual positive end-expiratory pressure (PEEP) and regular alveolar recruitment manoeuvres (ARM) of Central and Eastern European anaesthesiologists during general anaesthesia.
