The blue baby syndrome or cyanosis occurs when absolute amount of deoxygenated hemoglobin > 3g/dL which is typically reflected with an O 2 saturation of < 85 %. [ 1 ] Both of these conditions cause cyanosis , or a bluish discoloration of skin or mucous membranes. [ 4 ]
This results in a major risk of methemoglobinemia caused by nitrates ingested in drinking water, [13] dehydration (usually caused by gastroenteritis with diarrhea), sepsis, or topical anesthetics containing benzocaine or prilocaine resulting in blue baby syndrome. Nitrates used in agricultural fertilizers may leak into the ground and may ...
The mother’s immune system reacts to the Rh-positive red blood cells the same way that it would respond to something like a virus or bacteria, activating B cells — a type of white blood cell that is key to the triggering of an immune response. These activated B cells then differentiate into plasma cells, which produce anti-D antibodies.
The structure of cytochrome b5 reductase, the enzyme that converts methemoglobin to hemoglobin. [1]Methemoglobin (British: methaemoglobin, shortened MetHb) (pronounced "met-hemoglobin") is a hemoglobin in the form of metalloprotein, in which the iron in the heme group is in the Fe 3+ state, not the Fe 2+ of normal hemoglobin.
Elevated nitrate in groundwater is a concern for drinking water use because nitrate can interfere with blood-oxygen levels in infants and cause methemoglobinemia or blue-baby syndrome. [28] Where groundwater recharges stream flow, nitrate-enriched groundwater can contribute to eutrophication , a process that leads to high algal population and ...
A "rainbow baby" is the name given to a baby born following a miscarriage or stillbirth. The question comes in time for Pregnancy and Infant Loss Remembrance Day, which falls on Oct. 15, and ...
Nitrite is a precursor to carcinogenic nitrosamines, and; via the formation of nitrite, nitrate is implicated in methemoglobinemia, a disorder of hemoglobin in red blood cells susceptible to especially affect infants and toddlers. [11] [12]
A baby’s “beautiful big blue eyes”, which were complimented by everyone, turned out to be a symptom of a condition causing blindness. Louise Bice, 34, was stunned when her daughter, Aretria ...
