Active clinical trials for "Carbon Monoxide Poisoning"

This randomized trial will investigate important neurocognitive clinical outcomes of patients with acute severe carbon monoxide poisoning (ASCOP) randomized to receive either therapeutic hypothermia or normothermia combined with hyperbaric oxygen therapy (HBO).

The goal of this pilot, clinical, experimental, biological and prospective study with uso of biological material (venous blood sampling), in patient with acute carbon monoxide (CO) intoxication and in a group of healthy non-intoxicated subject (group of control) is the research of a possible increase of circulating microparticles level in human blood with an acute carbon monoxide intoxication. The main question to answer is: Is there an increase of circulating microparticles levels in subjects with acute carbon monoxide poisoning? Two blood samples will be withdrawn from patients with acute carbon monoxide poisoning, one before and one after hyperbaric oxygen treatment. Researchers will compare a group of healthy volunteers to see if there is a different in circulating microparticles blood level compared to patients with intoxication.

This prospective cohort study enrolls subjects who experience carbon monoxide (CO) poisoning. The purpose of the study is to evaluate therapeutic effects of various treatments and short and long-term outcomes in CO poisoned patients. In addition, complications of brain and heart susceptible to CO are investigated through various ways and the association between complications and the patient's prognosis is also investigated. All subjects will be regularly monitored by physicians participating in this study.

Carbon monoxide (CO) poisoning results in high morbidity and mortality worldwide. CO is described as a "silent killer" because CO is colorless, odorless, and tasteless but highly toxic. The diagnosis of acute CO poisoning depends on the history of exposure to a source of fire in a closed space along with the clinical and laboratory findings. The pathophysiology of CO poisoning is not fully understood; however, it is proved that CO induces hypoxia by forming carboxyhemoglobin (COHb) and shifting the oxygen dissociation curve to the left. The molecular mechanisms of CO poisoning include oxidative injury through the generation of free radicals. In addition, oxygen therapy might enhance the reactive oxygen species (ROS) production and result in reperfusion injury. Free radicals could induce a serious impact on vital organs, including the heart, and brain. L-Carnitine is an endogenous mitochondrial constituent that contributes to normal mitochondrial activities. L-Carnitine is an antioxidant with potent ROS scavenging ability. ROS-mediated pathology of CO suggests that antioxidants are potentially useful agents in the alleviation of CO toxicity. Thus, the current study will investigate the therapeutic efficacy of L-Carnitine in improving the prognosis of acute CO poisoning. The current clinical trial will include patients with moderate and severe acute carbon monoxide poisoning according to Poisoning Severity Score.

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.

Carbon monoxide poisoning still places a burden on the healthcare system worldwide. While oxygen therapy is the cornerstone treatment, the role and practical modalities of hyperbaric oxygen therapy (HBO) remain controversial. This study aimed at comparing two sessions of HBO at 2 absolute atmosphere and one session of HBO at 2 absolute atmosphere followed by 4 hours of normobaric oxygen therapy in comatose adult victims of acute domestic carbon monoxide poisoning.

While oxygen therapy is the cornerstone treatment, the role and practical modalities of hyperbaric oxygen therapy (HBO) remain controversial. This study aimed at comparing one session of HBO at 2 absolute atmosphere followed by 4 hours of normobaric oxygen therapy to 6 hours of normobaric oxygen therapy in adult victims of acute domestic carbon monoxide poisoning and without coma.

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.

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.
