13 Clinical Trials for Various Conditions
The purpose of this study is to collect non-invasive observational data in suspected or known carbon monoxide poisoning.
The purpose of this study is to collect non-invasive opportunity sample data in suspected or known cases of carbon monoxide poisoning.
The purpose of this study is to determine whether a relationship exists between EtCO2 and carboxyhemoglobin levels in carbon monoxide exposure. Our hypothesis is that a liner relationship exists between EtCO2 and carboxyhemoglobin in carbon monoxide poisoning.
Carbon monoxide poisoning is common. Many adults with CO poisoning have long-term, even permanent brain injury following poisoning. However, very little is known about the long-term outcome of children with carbon monoxide (CO) poisoning. In this study we plan to perform cognitive (thinking) and vestibular (balance) testing in children (ages 6 to 16)at 6 weeks and 6 months following CO poisoning. At the 6-week visit, if the child and parents agree, we will ask each child to provide a DNA sample by one of three methods: mouthwash, spit collection, or swabbing the inside of the child's cheek. Each child's DNA will be analyzed for genes that are known to affect outcome following brain injury.
That SPECT brain imaging tracks and is consistent with clinical history and physical exam as well as cognitive testing.
This randomized trial will investigate important clinical outcomes of patients with acute carbon monoxide poisoning randomized to receive either one or three hyperbaric oxygen treatments.
Hyperbaric Oxygen Therapy (HBO) is routine treatment of carbon monoxide (CO) poisoning to prevent delayed neurological sequelae. This study looking to see if neurologic outcomes are improved with the addition of dexamethasone. CO poisoning can initiate a free radical mediated process that can instigate a demyelinating process resulting in long term neurological sequelae in some, but not all patients. In other demyelinating disorders, steroids are a part of first line treatment. HBO is already used for acute CO poisoning, so this pilot study will try to ascertain if the addition of steroids in concert with each hyperbaric oxygen session will yield improved outcomes.
The purpose of the study is to assess device performance in the presence of carbon monoxide.
In this study, the investigators will collect EEG data in normal, healthy volunteers without a history of prior brain injury. This data will be analyzed by computer (quantitative, or qEEG) and stored in a normative database so that, in the future, the investigators can better understand and characterize the brain damage that can result from carbon monoxide (CO) poisoning and other types of brain injury.
The purpose of this biorepository is to collect blood from patients at the time of CO poisoning and at follow-up visits months to years later. These samples can be used in the future to learn more about how CO damages the heart and brain and whether blood tests could predict which patients will have problems after CO poisoning.
Carbon monoxide (CO) has been called a "silent killer", and those patients who survive CO poisoning are at risk of neurological damage, which may be permanent. CO is a leading cause of unintentional poisoning deaths in the United States, and the odorless gas results in an estimated average of 20,636 emergency department (ED) visits each year. Oxygen is the antidote for CO poisoning, and it acts both by attenuating toxic effects and enhancing elimination. A fractional inspired concentration of oxygen (FiO2) of 0.7 to 0.9 may be achieved by administration of 100% oxygen delivered using a reservoir with a facemask that prevents rebreathing. Hyperbaric oxygen therapy may provide added benefit for patients with CO poisoning, but this therapy is unavailable in many parts of the United States including Vermont. Use of a continuous positive airway pressure (CPAP) mask may achieve an FiO2 of 1.0, but the effects of delivering an FiO2 of 1.0 compared to 0.7 in CO poisoning are unknown. CPAP, by comparison, is inexpensive, portable, and available in most EDs. In this study, the investigators are testing the hypothesis that oxygen delivered by CPAP will improve both CO washout kinetics and functional outcomes, compared to the standard therapy of oxygen delivered by non-rebreathing facemask. Specific Aim 1 will provide toxicokinetic data to support a potential benefit in the use of CPAP for CO poisoning, by comparing CO elimination kinetics in response to oxygen therapy delivered by non-rebreathing facemask versus CPAP. The 20 patients expected in our first year will provide adequate power to detect a 20% fall in half-time of CO elimination. While CPAP may increase CO washout rates, as predicted in Specific Aim 1, demonstration of real functional benefit will be tested in Specific Aim 2. This Aim seeks to determine functional (neuropsychological) outcomes in patients with CO poisoning treated with oxygen therapy delivered by non-rebreathing facemask versus CPAP. Data showing a therapeutic benefit from CPAP in CO poisoning would have clinical implications. Compared to hyperbaric oxygen therapy, CPAP therapy can begin earlier, including the pre-hospital setting, for patients with known exposure. With the frequent nature of CO poisoning and the widespread availability of CPAP, a potential benefit could lead to improved outcomes for the 20,000+ patients who present to EDs annually.
The 'Analysis of Emergency Department Volumes during Natural Disasters' retrospective study focuses on three specified populations including dialysis patients, trauma patients, and patients poisoned by carbon monoxide. These three populations have one commonality - hurricanes, ie. natural disasters, which is the exposure. Causal associations and significant correlations will be explored in all three subgroups.
Carbon Monoxide (CO) exposure kills and injures thousands of children and families each year. Although there is growing concern about the need to increase carbon monoxide detector use, little is known about how best to do so, especially for low-income families. The objective of this research is to determine whether a brief intervention, Project Carbon Monoxide Detector Education (Project CODE), will increase CO detector use. For this study, parents of children, 18 years or younger, will be randomly assigned to receive Project CODE (an educational tool and a CO detector) or usual care (a flyer on CO poisoning); both of which will be delivered in the Pediatric Emergency Department (PED) examination rooms. The use of a CO detector and the participant's current stage in the theory of stage-based behavior change-the Precaution Adoption Process Model (PAPM), will be assessed at enrollment and then again at the home visits which will occur two-weeks and six-months following the PED visit. The investigators hypothesize that parents receiving Project CODE will have working CO detectors and will be further along in the PAPM than parents in the control group at the two-week and six-month home visits. The long term goal of this research is to reduce the number of injuries and deaths from CO poisoning.
