The aim of this study was to make a retrospective descriptive analysis of the features of children with acute carbon monoxide poisoning (COP). We evaluated 74 children (43 girls, 31 boys; age range 1 to 17.8 years) who were consecutively admitted to our emergency unit and hospitalized with accidental acute COP between June 2003 and June 2005. All patients received normobaric oxygen therapy unti...

Carbon monoxide (CO) is a colorless, tasteless, odorless, and non-irritating gas formed when carbon in fuel is not burned completely. It enters the bloodstream through the lungs and attaches to hemoglobin (Hb), the body's oxygen carrier, forming carboxyhemoglobin (COHb) and thereby reducing oxygen (O(2)) delivery to the body's organs and tissues. High COHb concentrations are poisonous. Central ...

Blood samples submitted to the Civil Aeromedical Institute (CAMI) from aviation accident fatalities are analyzed for carbon monoxide (CO), as carboxyhemoglobin (COHb), and hydrogen cyanide, as cyanide (CN(-)). These analyses are performed to establish possible exposure of victims to smoke from in-flight/post-crash fires or to CO from faulty exhaust/heating systems. The presence of both gases in...

Methodology: Cardiovascular system examination and Electrocardiography (ECG) were performed for fifty CO intoxicated patients admitted to Poison Control Center, Ain Shams university Hospital for whom some oxidative stress indices have been investigated through the assessment of plasma level of malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide (NO). Both cardiac enzymes; troponi...

Carbon monoxide (CO) poisoning is an important public health issue, as this colorless, odorless gas is a common cause of unintentional poisoning and leads to over 400 deaths each year in the United States.1 Detection of CO poisoned patients may be difficult, as even classic symptoms, including headache, nausea, dizziness, and fatigue, are vague and nonspecific, and poisonings may occur without ...

and injury are well-known complications of CO poisoning, possibly more prevalent in patients with pre-existing atherosclerotic coronary artery disease. As Dr. Marius-Nunez points out, hypoxic injury is multifactorial, probably related both to CO binding to hemoglobin and also to direct cellular effects of CO. All patients with carbon monoxide exposure should undergo routine electrocardiography ...

Aim: Acute carbon monoxide (CO) poisoning is a potentially mortal, though preventable, condition. Mild presents with non-specific symptoms, such as fatigue, headache, nausea and vomiting, whereas severe exposure to CO can result in loss of consciousness, coma, death. The aim this study was investigate the utility lactate carboxyhemoglobin (COHb) levels clinical presentation treatment patients a...

OBJECTIVE The purpose of this study was to evaluate the ability of multiple wavelength pulse CO-oximetry (SpCO) to screen for environmental tobacco smoke (ETS) exposure in children. BACKGROUND Exposure to ETS is associated with an increased risk of perioperative respiratory complications in children. It is often difficult to obtain an accurate history for ETS exposure, so a preoperative scree...

The purpose of this study was to verify the previously reported shorter half-time of elimination (t½) of carbon monoxide (CO) in females compared to males. Seventeen healthy subjects (nine men) completed three sessions each, on separate days. For each session, subjects were exposed to CO to raise the carboxyhemoglobin percentage (COHb) to ~10%; then breathed in random order, either (a) 100% O2 ...

BACKGROUND Diffusing capacity of the lung for carbon monoxide (D(LCO)) can be affected by abnormal hemoglobin (Hb) or carboxyhemoglobin (COHb) levels. Predicted D(LCO) can be adjusted to reflect abnormal Hb or COHb levels. Until recently, blood sampling was required to determine Hb and COHb levels, but a new pulse oximeter, the Masimo RAD-57, can measure Hb and COHb noninvasively. We hypothesiz...
