简要总结
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 Two blood samples will be withdrawn from patients with acute carbon monoxide poisoning, one before and one after hyperbaric oxygen treatment.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.
详细描述
Few agents cause suffering like carbon monoxide (CO) in the humans. The CO pathophysiological mechanism extends beyond the hypoxic stress given by the COHb, and current knowledge cannot explain all of the lesions.
CO toxicity includes hypoxic and oxidative stress and implies long-term neurological morbidity. Patients exposed for a short time even to low concentrations of CO may show activation of intravascular neutrophils and increases in circulating inflammatory proteins.
The treatment of CO poisoning is administer normobaric or hyperbaric oxygen. One of the possible complications of CO poisoning is the delayed neurological syndrome.
Microvesicles are microparticles released by all eukaryotic cells and are involved in the intracellular communication, in physiological and pathological conditions.
In the human blood microparticles are present after exposure to tobacco smoke and air pollution.
