Phenolic poisoning

Introduction to phenolic poisoning Commonly used phenolic drugs are lime acid (phenol), lysine (coal phenol soap solution), creosote, leucine (resorcinol), hexachlorophene, stinky water (coal tar soap solution) Etc., in which carbolic acid is the most toxic and corrosive, phenols have stimulating, paralyzing and causing necrosis on the skin and mucous membranes. After absorption, the effect on the central nervous system is first stimulated and then inhibited, and can directly damage the heart muscle and small blood vessels. Wait. Pediatric poisoning is caused by accidental use; if you use a lot of rubbing the skin, it can also cause poisoning due to rapid absorption. Oral poisoning quickly to the raw egg white or milk orally, so that combined with phenol, then use micro-warm water or vegetable oil (castor oil) gastric lavage, until the eluate is clear and no phenolic taste, after the gastric lavage, 60 ~ 90ml of vegetable oil in the stomach In order to prevent the absorption of residual phenol and protect the gastric mucosa. After the gastric lavage, milk, raw egg white, soy milk, aluminum hydroxide gel, etc. can be given. Gastric lavage is very important, even if it takes a little longer. If the corrosion is heavy, it should be done with caution. Avoid using mineral oil and alcohol, because it can increase the absorption of phenol by the stomach. After gastric lavage, a small amount of vegetable oil (castor oil) is poured into the stomach, and the sodium sulfate or magnesium sulfate is used for catharsis. basic knowledge Sickness ratio: 0.5% Susceptible people: no special people Mode of infection: non-infectious Complications: coma, low blood pressure

Causes of phenolic poisoning

envirnmental factor:

Poisoning caused by phenols is mainly caused by accidental oral or skin contact in occupation or daily life, among which oral administration is more common, and a small number of cases are caused by excessive medical use or suicide.

Phenolic poisoning prevention

The phenolic products commonly used in the family, such as Lai Su disinfectant, have a low concentration, and generally do not cause symptoms when in contact with the skin. When the amount of contact is large, rinse with water. Workers who are frequently exposed to phenolic products in their occupations should take certain protective measures to avoid skin and eye contact.

Phenolic poisoning complications Complications, coma, hypotension

There may also be drowsiness, coma, convulsions, cough, hypotension, accelerated breathing, palpitation, abnormal liver function, kidney failure, urine may be dark green or black and other complications, and can die in severe cases.

Symptoms of phenol poisoning Common symptoms Shock coma diarrhea Blood pressure drop nausea and abdominal pain

After being mistreated, it can cause burns, rot, necrosis, etc. in the mucous membranes of the lips and mouth, throat, esophagus, gastrointestinal, etc. The sick child feels burning pain in the above parts, and has nausea and vomiting. The spit can be bloody or white. Clot (corrosive tissue), dysphagia, abdominal pain, diarrhea, headache, tinnitus, exhalation and vomit have phenolic taste, feces with blood, kidney damage is less, urine is less, dark green, gradient black, of which Contains protein, hemoglobin, casts and phenols, severe uremia, liver damage, jaundice, severe convulsions, coma, dilated pupils, tachycardia, decreased body temperature and blood pressure, paralysis, reflexes disappear Even in the crisis several minutes after the occurrence of shock and respiratory failure, there may be sequelae of esophageal stenosis, and occasional methemoglobinemia may occur in children.

Examination of phenol poisoning

Analysis of vomit and urine toxicants, black in the diagnosis.

Diagnosis and identification of phenol poisoning

In the summer easy poisoning season, it should be differentiated from heatstroke and acute gastroenteritis. In addition, the clinical manifestations of acute dinitrophenolic compound poisoning are similar to those of pentachlorophenol poisoning, and attention should be paid to distinguish them.
