Which type of poisoning should not be treated with gastric lavage?

Introduction
In general, gastric lavage is contraindicated in cases of poisoning by concentrated sulfuric acid, benzene, aniline, cyanide, and strong alkalis. Additionally, gastric lavage should also be avoided in poisoning by concentrated hydrochloric acid or concentrated nitric acid. Patients are advised to seek prompt medical attention when experiencing discomfort and to receive standardized treatment under a physician's guidance, which can facilitate recovery. Concentrated sulfuric acid releases a large amount of heat when reacting with water.

In general, gastric lavage is contraindicated in cases of concentrated sulfuric acid poisoning, benzene poisoning, aniline poisoning, cyanide poisoning, and strong alkali poisoning. The specific reasons are as follows:

1. Concentrated Sulfuric Acid Poisoning

Concentrated sulfuric acid reacts with water to release a large amount of heat, which can damage the gastrointestinal mucosa. When diluted with water, concentrated sulfuric acid becomes dilute sulfuric acid, causing even greater harm to the gastrointestinal tract. In severe cases, this may lead to gastric perforation or massive upper gastrointestinal bleeding, potentially triggering shock and respiratory failure. Therefore, gastric lavage is strictly prohibited in cases of concentrated sulfuric acid poisoning.

2. Benzene Poisoning

Benzene is readily absorbed into fatty tissues and is irritant in nature. Performing gastric lavage may accelerate the absorption of benzene; therefore, it is not recommended.

3. Aniline Poisoning

Aniline is a strongly alkaline substance. Gastric lavage may exacerbate tissue damage at injury sites and accelerate kidney damage.

4. Cyanide Poisoning

Cyanide is rapidly converted into hydrocyanic acid in the body. Extensive absorption of hydrocyanic acid can cause severe metabolic acidosis. Gastric lavage may accelerate cyanide absorption, thereby worsening the condition.

5. Strong Alkali Poisoning

Strong alkalis react with gastric acid to produce substantial heat and gas. Gastric lavage may push the alkali deeper into the esophagus and stomach, leading to chemical burns and hemorrhage.

In addition, gastric lavage is also contraindicated in poisoning caused by concentrated hydrochloric acid, concentrated nitric acid, and similar substances. Patients experiencing any discomfort should seek prompt medical attention and receive standardized treatment under the guidance of a physician to facilitate recovery.

What is the incubation period in years after ingesting glufosinate?
Glufosinate has no clearly defined latency period after ingestion. Symptoms of poisoning usually develop acutely within hours after intake, and there are no cases in which symptoms appear years later. The greater the ingested dose, the more severe the symptoms, making it highly dangerous. If glufosinate is accidentally ingested, regardless of the amount, immediate medical attention and professional treatment are essential. Glufosinate is a non-selective herbicide, and its toxicity primarily...

Will burning charcoal in a room cause poisoning?
If a room's doors and windows are tightly closed or ventilation is poor, burning charcoal can produce carbon monoxide, a colorless, odorless gas that is difficult to detect. This gas can easily accumulate indoors in large amounts. When inhaled, it may cause poisoning, leading to symptoms such as dizziness, nausea, and difficulty breathing. In severe cases, it can be life-threatening. Therefore, burning charcoal indoors is absolutely not recommended.

What to do for chlorine dioxide poisoning
In case of chlorine dioxide poisoning, immediately leave the contaminated environment, maintain airway patency, remove any residual toxin from the body surface, provide symptomatic relief, and seek prompt medical attention. If symptoms such as coughing, chest tightness, dizziness, or vomiting occur, it is essential to go to a正规 hospital as soon as possible. Quickly move to a well-ventilated area with fresh air and stay away from areas containing chlorine dioxide.

Why do I feel cold and shiver all over after drinking alcohol?
In general, feeling cold and shivering after drinking alcohol may be caused by alcohol-induced blood vessel dilation, heat production from alcohol metabolism, hypoglycemia, common cold, acute alcohol poisoning, or cerebral hemorrhage. If such symptoms occur, it is recommended to seek medical attention promptly and receive targeted treatment after identifying the underlying cause. After alcohol enters the body, it causes peripheral blood vessels to dilate, increasing blood flow to the skin surface and accelerating heat loss from the body.

Is there an incubation period for poisoning from eating wood ear mushrooms?
Under normal circumstances, poisoning from consuming black fungus (wood ear mushroom) usually has an incubation period, the duration of which varies depending on factors such as the type of toxin, amount ingested, individual differences, and cooking methods. When rehydrating dried black fungus, use clean lukewarm water for no more than 2 hours; if room temperature is high, it can be refrigerated. Thoroughly wash and fully cook the fungus before consumption—avoid eating it raw or undercooked.
