30 Possible Causes for Chocolate-Brown Colored Blood

  • Methemoglobinemia

    All patients manifested cyanosis, low oxygen saturation and chocolate-brown-colored blood despite supplemental oxygen therapy.[ncbi.nlm.nih.gov] The main symptoms are: cyanosis, which describes a bluish color of the skin, especially the lips and fingers chocolate-brown colored blood It’s because of cyanosis that some[healthline.com] His blood was chocolate brown in color.[ijccm.org]

  • Nitrite Poisoning

    Nitrite poisoning is distinguished by the appearance of cyanosis that is not improving after supplementation with oxygen and by observing a brown to chocolate color of blood[symptoma.com] It turns the fish’s blood to a chocolate-brown color.[koihealth.info] Methemoglobin concentration of about 40% causes the blood to become chocolate brown and pale brown gills. 6. Anemic fish have pale gills but with red tinge 7.[aun.edu.eg]

  • Aniline Poisoning

    Abstract A case of aniline poisoning with methemoglobinemia unresponsive to methylene blue is described. Exchange transfusion proved successful. A rationale for the failure of methylene blue under these circumstances is described.[ncbi.nlm.nih.gov]

  • Congenital Methemoglobinemia

    We report a case of methaemoglobinaemia which was first diagnosed in the intraoperative period due to appearance of chocolate brown colored blood after surgical incision.[omicsonline.org] The main symptoms are: cyanosis, which describes a bluish color of the skin, especially the lips and fingers chocolate-brown colored blood It’s because of cyanosis that some[healthline.com] Case history 2: Chocolate-brown-colored blood suggests methemoglobinemia Blood containing a high concentration of methemoglobin is chocolate brown in color rather than the[acutecaretesting.org]

  • Nitrobenzene Poisoning

    Methemoglobinemia should be suspected clinically by the presence of cyanosis in the presence of a normal PaO2 and chocolate-brown colored blood.[japi.org] Blood samples were arterial blood gas (ABG) analysis had a chocolate brown color, which did not improve on exposure to 100% oxygen and compensated metabolic acidosis.[documents.tips] Blood samples drawn for arterial blood gas (ABG) had a chocolate brown color, which did not improve on exposure to 100% oxygen and showed compensated metabolic acidosis [Table[mjmsr.net]

  • Inhalation Burn

    Additional clinical findings may include chocolate brown-color blood and cyanosis (despite normal pulse oximetry) that is not responsive to oxygen therapy. 13 Carbon Monoxide[emsworld.com]

  • NADH Cytochrome B5 Reductase Deficiency

    Case history 2: Chocolate-brown-colored blood suggests methemoglobinemia Blood containing a high concentration of methemoglobin is chocolate brown in color rather than the[acutecaretesting.org] This can give the blood a bluish or chocolate-brown color.[flipper.diff.org] Gas (ABG) Appearance of Blood in ABG Syringe : chocolate or brown-blue color pO2 : normal Note that the pO2 reflects the plasma oxygen content and does not reflect the oxygen-carrying[mdnxs.com]

  • Nitrate Poisoning

    The blood will also turn a chocolate-brown color, which reflects the lack of oxygen.[extension.missouri.edu] The most common symptom of nitrate poisoning is a bluish color to the skin, particularly around the eyes and mouth.[extension.missouri.edu] As the amount of methemoglobin increases, the amount of oxygen in the blood decreases, eventually causing internal suffocation.[extension.missouri.edu]

  • Sodium Nitrite

    Autopsy findings showed no significant macroscopic or microscopic findings except blood tinted chocolate brown color and chronic atopic dermatitis over the whole surface of[ncbi.nlm.nih.gov] Quantitation of the methemoglobin (MetHb) in the blood was performed using spectrophotometer; MetHb concentration of the blood was 76%.[ncbi.nlm.nih.gov]

  • Inhalation of Noxious Gases

    Additional clinical findings may include chocolate brown-color blood and cyanosis (despite normal pulse oximetry) that is not responsive to oxygen therapy. 13 Carbon Monoxide[emsworld.com]
