Filter by:Nitric oxide (NO) plays a pivotal role in maintenance of normal vascular tone. However, in sepsis the excessive production of NO results in myocardial depression, vasoplegia, and cytotoxic effects, thus promoting shock and multiple organ dysfunction. A recently completed study from our group showed advantageous cardiovascular effects of continuously infused methylene blue (MB), an inhibitor of NO pathway, in human septic shock. In another investigation, we have found that the combination of inhaled NO and continuously infused MB attenuates endotoxin-induced acute lung injury (ALI) in sheep. Our intention is, in a new study, to test the hypothesis that the combination of MB and NO (MB+NO) improves both cardiovascular and pulmonary functions as well as clinical outcome in patients with septic shock and ALI. Forty mechanically ventilated patients diagnosed with hyperdynamic septic shock and ALI, will be randomized to groups receiving 1. Conventional treatment (control group)(n =10); 2. MB infusion in addition to conventional treatment (n=10); 3. Inhaled NO in addition to conventional treatment (n=10); 4. MB infusion combined with inhaled NO (MB+NO) in addition to conventional treatment (n=10).
Extracorporeal membrane oxygenation (ECMO) is a means of artificially performing the function of the human lung and/or heart outside the body. Its use is escalating in a wide range of clinical settings in the adult population without evidence or guidelines to support this practice. This study involves a nationwide questionnaire which has two components. The initial pilot survey will attempt to identify all institutions currently practicing ECMO or those intending to do so in the future, and are willing to participate in prospective data collection. The second phase will involve a monthly survey of these centres regarding the extent of ECMO use, practice details implemented, and outcome data. It is hoped that the collection of this information will later assist in the development of guidelines for this expensive and presently unsubstantiated practice, together with the construction of appropriate training programs for staff.
The acute respiratory distress syndrome (ARDS) is an important cause of acute respiratory failure with a high mortality rate. The mechanism of resolution of the late organizing phase remains uncertain. The ACE gene contains a polymorphism based on the presence (insertion, I) or absence (deletion, D) within an intron of a 287-bp nonsense DNA domain, resulting in three genotypes (DD and II homozygotes, and ID heterozygotes). It has been shown that I/D polymorphism of ACE gene may account for half the variance of serum ACE levels in the Caucasians. Polymorphism of the ACE gene has also been shown to contribute to the development of some respiratory diseases. We hypothesize that the presence of ACE gene polymorphism can affect the outcome of ARDS. The objective of this proposed study is to determine the genotypes of ACE gene polymorphism and assess the influence of ACE genotype on the outcome and pulmonary resolution of patients with ARDS. Patients diagnosed to have ARDS are eligible for possible inclusion into the study. The ACE genotype of all patients with ARDS will be determined by polymerase chain reaction (PCR) amplification of the respective fragment for the D and I alleles from intron 16 of the ACE gene and size fractionation by electrophoresis. The outcome of patients with ARDS in the three genotypes will be compared.
King County Lung Injury Project: Survivor Outcome Study (KCLIP:SOS) is a randomized trial for individuals who have survived prolonged mechanical ventilation (5 days or more). The objective is to enroll individuals who are likely to have impaired health status resulting from prolonged critical illness but whose long term prognosis is good. Such individuals are most likely to benefit from the study intervention of case management targeted at post intensive care complications. KCLIP:SOS will test whether an outpatient intervention based on a nurse using a targeted case management tool can reduce patient morbidity and improve quality of life in the 6 months following hospital discharge. This intervention will be compared to usual post-hospital care.
The investigators aim to study the specific elastance in ALI/ARDS patients during invasive mechanical ventilation.
The study is a chart review of all children admitted over a two year period with the diagnosis of acute respiratory distress syndrome. Short term outcomes, such as mortality, length of ventilation and length of stay, will be reviewed. Factors that impact these outcomes will also be reviewed.
The purpose of this study is to determine the effectiveness of etanercept in the treatment of patients with sub-acute lung injury following a bone marrow transplant. This study will also examine the toxicity of treatment with etanercept as well as whether there is an improved quality of life in these patients.
The purpose of this trial is to test the hypothesis that at the end of 28 days, infants and children with acute lung injury treated with prone positioning would have more ventilator-free days than those treated with supine positioning.
The purpose of this study is to see whether esophageal pressure (PES) measurements will allow the investigators to choose the best method of mechanical ventilation in patients with acute lung injury (ALI).
The purpose of this study is to evaluate the clinical outcome of patients following blunt traumatic injury with hypovolemic shock, who receive either lactated ringer's solution or hypertonic saline with dextran (HSD) resuscitation; also, to focus specifically on neurologic outcome in patients with brain injury and on the effect of HSD resuscitation on inflammatory cell responsiveness.
