Chemical burns - phosphorus burns
- Sep 21, 2018 -

Phosphorus burns are often seen in industrial and agricultural production, and phosphorus bomb explosions often cause burns during wartime. Phosphorus and phosphorus compounds are highly flammable in air and oxidized to phosphorus pentoxide. The wound can smoke during the day. There is phosphorescence at night. This is why phosphorus continues to burn on the skin. Therefore, the wound surface is deeper, and phosphorus is a highly toxic substance that can cause systemic poisoning after being absorbed by the body.

Phosphorus is highly toxic to the liver, causing necrosis of liver cells and hepatic steatosis. It can cause extensive bleeding to vascular injuries: it is toxic to the kidneys, heart muscles and nerves.

Patients with phosphorus poisoning generally have exhaustion, dizziness, headache, general malaise, pain in the liver area, swelling, jaundice, and abnormal liver function. There is less urine, red urine and protein appear in the urine test, hematuria can also be seen, and severe urine is closed. Subcutaneous capillary hemorrhage, visible purple sputum (red small bleeding point, pressure does not fade). In severe cases of liver damage, toxic hepatitis can occur, and acute yellow liver atrophy can cause death.

The principle of first aid treatment is to extinguish the phosphorus and then wrap it with the relevant liquid. If phosphorus is still burning on the skin, it should be quickly extinguished and rinsed with plenty of water. After rinsing, carefully check the presence or absence of residual phosphorus, or observe it in the dark. If there is illuminating place, remove it with a small tweezers, then cover with a l% copper sulfate gauze to make residual phosphorus. Black phosphating triple copper, then rushing away. It can also be washed with 3% hydrogen peroxide or 5% sodium hydrogencarbonate solution to oxidize phosphorus to phosphoric anhydride. If there is no such liquid, you can rinse the area with plenty of water.

General burns are often used in the oil yarn layout department, but should be disabled in the case of phosphorus injury. Because phosphorus is easily soluble in oil, it causes the body to absorb and cause systemic poisoning. Instead, it is applied with 2.5% sodium bicarbonate solution for two hours, then wrapped with dry gauze.

For systemic poisoning, the main treatment is to protect the liver, such as intravenous injection of 50% hypertonic glucose solution, or intravenously 5-10% glucose solution, adding a large amount of vitamin C. Take other liver protection drugs such as Liver. If there is proteinuria or hematuria in the kidney, it can be injected with alkaline drugs such as sodium bicarbonate and rest in bed.
