Methemoglobin

01/01/2014 - "When he arrived at a regional hospital, he was drowsy with cyanosis and his initial serum methemoglobin (MetHb) level was 59.5%. "
03/01/2013 - "Spontaneously, the cyanosis gradually decreased and by the fifth month of age the methemoglobin level was normal. "
07/01/2009 - "Here we report a six-year old boy who presented with central cyanosis and upon examination revealed a methemoglobin level of 19.0%. "
11/01/2008 - "When the concentration of methemoglobin in the blood is above 1.5%, the patient develops cyanosis, the main characteristic of this disorder. "
04/01/2005 - "Patients develop profound cyanosis unresponsive to O2 when methemoglobin (MHb) levels exceed 10%. "

07/01/2012 - "These studies have demonstrated that 3-AP induces methemoglobin (metHb) formation and hypoxia in patients, limiting its usefulness. "
07/01/2010 - "The purpose of our study was to determine whether hypoxia affects the new device's estimated methemoglobin reading accuracy, and whether the presence of methemoglobin impairs the ability of the Radical-7 and a conventional pulse oximeter (Nonin 9700, Nonin Medical Inc., Plymouth, MN) to detect decreases in Sao2. "
04/01/1999 - "The study showed that the discrepancy in the results observed may be attributed to the presence of the methemoglobin and possible to anaemia associated to hypoxia."
12/15/1977 - "In this study, hematocrits and methemoglobin levels were monitored in rats exposed to hypoxia (420 torr absolute) for various intervals. "
12/01/2014 - "Storage of RBCs leads to an increased rate of hypoxia-induced nitrite reduction to NO and this is associated with increased methemoglobin formation. "

04/01/2015 - "In the prospective part of the study, none of 18 patients [16 (89 %) men, mean age 63 ± 13] was diagnosed with either clinical symptoms of methemoglobinemia or exceeded normal blood concentration of methemoglobin. "
12/01/2015 - "We suspected methemoglobinemia based on the gap between SpO2 and PaO2 , and subsequently detected increased methemoglobin at 8.0%. "
04/01/2015 - "Methemoglobinemia was diagnosed on the basis of saturation gap and elevated methemoglobin levels. "
03/01/2015 - "Due to the various causes of methemoglobinemia and its potential to be confused with other diseases, in vivo measurements of methemoglobin have significant applications in the clinic. "
02/01/2014 - "The methemoglobin level of 91% in our patient is the highest level reported among methemoglobinemia survivors. "

01/01/2003 - "Methemoglobin (MHb) formation is effective in treating cyanide (CN) poisoning. "
09/01/1996 - "This study tested whether exogenous stroma-free methemoglobin (SFmetHb) can prevent depression of hemodynamics and metabolism during canine cyanide poisoning. "
01/01/1983 - "Stroma-free methemoglobin solution as an antidote for cyanide poisoning: a preliminary study."
09/01/2014 - "Of the 824 patients admitted with poisoning, 5 patients with methemoglobin concentration greater than or equal to 49% were included. "
01/01/2011 - "Methemoglobin (MetHb) is a significant clinical problem for some poisonings. "

01/01/2013 - "Is methemoglobin an inert bystander, biomarker or a mediator of oxidative stress--The example of anemia?"
04/01/2010 - "Regenerative anemia (Hematocrit 22%) and the elevated methemoglobin (8.7%) concentration were detected upon hematological examination. "
08/01/1996 - "Dogs receiving APHZ showed anemia after dosing for 7 days, together with an increase in methemoglobin and Heinz body formation after 3 days of dosing. "
10/01/1990 - "Blood methemoglobin levels were elevated in the mid- and high-dosage groups, while slight anemia was observed in the high-dosage group also. "
01/01/2013 - "During acute anemia, we have observed a small but consistent increase in methemoglobin (MetHb) levels that is inversely proportional to the acute reduction in Hb observed during hemodilution in animals and humans. "
