Ajarn Od" points out that cyanide is easy to find. mechanism of poisoning inhibits cellular respiration If cyanide is taken on an empty stomach, the duration of action will be in minutes. But if the stomach is full of food, it will delay death by hours.
Dr. Wirachai Phutthawong or Ajarn Aod Lecturer, Department of Chemistry Faculty of Arts and Sciences Kasetsart University Personal Facebook post about cyanide that it's easy to find. Cyanide is rat poison. Whoever gets hit is like suffocating.
Mechanism of cyanide poisoning Occurs from binding to Cellular Cytochrome Oxidase, resulting in cells unable to use oxygen. (Inhibition of cellular respiration) Patients often have brain symptoms such as seizures, unconsciousness, and abnormal breathing. due to pressure on the respiratory control center But the patient does not turn blue (cyanosis) in the early stages even though he stops breathing. because the body cannot use oxygen Clinically, the diagnosis can be confirmed by fundi examination, which shows no difference in the color of the veins and red veins in the retina.
There are many types of cyanide, such as sodium cyanide. potassium cyanide or found in the form of other salts such as calcium cyanide Iodine cyanide, etc. Cyanide can kill people quickly. It can enter the human body from many routes. including inhaling cyanide gas Taking cyanide tablets and liquids or even exposure to cyanide
If cyanide is ingested on an empty stomach, the duration of action will be in minutes. But if the stomach is full of food, it will delay death by hours instead. Because in the stomach there is acid used in digestion. Taking cyanide salts on an empty stomach Cyanide reacts with stomach acid. a cyanide gas in the stomach and fast acting But if hydrogen cyanide is inhaled, it will die within seconds.
Cyanide concentration has a large effect on speed. If a man was locked in a 1x1x1 meter gas chamber and released about 300 milligrams of hydrogen cyanide, he would die instantly. But if 150 milligrams of hydrogen cyanide was given, he would have about 30 minutes before his death. But if only 20 milligrams of gas was released, he would not have died. Only there will be a slight abnormality
