Ascariasis is a disease caused by ascaris parasitic on human small intestine. Oral infection of larval eggs is the main route of human infection with ascaris lumbricoides.

[etiology]

[epidemiology]

[Clinical manifestations]

Larva migrans.

It is found in people who eat vegetables and fruits containing a large number of fertilized ascaris eggs in a short time. The incubation period is 7-9 days. Low fever, fatigue, a few accompanied by urticaria or rash. Foreign body sensation in the pharynx, sudden cough, asthma-like attacks, little phlegm, occasional bloodshot phlegm, and dry rales in the chest. At 1-2 weeks, bilateral hilar shadows deepened, lung texture increased, and punctate, flaky or flocculent infiltration shadows disappeared. Sputum examination may include eosinophils and Charcot-Leiden crystals, and occasionally larvae. The course of the disease lasted for 7- 10 days and gradually relieved.

1. Enteroascariasis

Most cases have no symptoms. Children often have abdominal pain, which is irregular and repeated abdominal pain around the navel. There is no tenderness and abdominal muscle tension, accompanied by anorexia, nausea, diarrhea or constipation, and ascaris is discharged in the stool. Children sometimes have convulsions, night terrors, grinding their teeth and pica.

complication

The clinical manifestations of biliary complications are biliary colic, acute cholecystitis, acute cholangitis, acute pancreatitis and liver abscess.

Intestinal complications are mechanical intestinal obstruction, mostly incomplete. Paroxysmal periumbilical pain, frequent vomiting, obvious abdominal distension, intestinal type, peristalsis wave. Touching a cord-like mass in the abdomen is the characteristic of this disease. X-ray plain film shows liquid level and intestinal expansion. Long-term obstruction may be complicated with intestinal perforation and volvulus. Ascaris can cause appendicitis when it enters the appendix.

Ascaris peritonitis Ascaris can enter the abdominal cavity through the small intestinal wall, causing abdominal pain, bloating, total abdominal tenderness and other symptoms of peritonitis. Ascaris and egg granuloma can be found during operation.

[diagnosis]

[therapy]

1. Insect repellent treatment

Benzimidazole is a broad-spectrum nematicide. Albendazole 400 mg, oral. Mebendazole is a C-shaped crystalline particle, 500mg. Ascaris can be eliminated in 2-4 days. The curative effect is above 90%, and there is generally no side effect.

Thiopyrimidine broad-spectrum nematicide. Adults 500mg, taken suddenly. Children take 10mg/kg each time. Pregnant women, patients with liver, kidney and heart disease should stop using it.

Piperazine has anticholinergic effect, which paralyzes the muscles of worms. Adult 3g, children 80- 100 mg/kg, fasting or at night 1 time, for 2 consecutive days. Patients with liver and kidney diseases and epilepsy are prohibited. The first cure rate is 70%-80%.

Levamisole 150-200mg for adults, taken suddenly. Occasionally it may cause toxic encephalopathy and should be used with caution.

Treatment of biliary ascariasis

The principle is to relieve spasm and pain, and to repel insects and resist infection at an early stage. Atropine 0.5mg plus promethazine 25mg, intramuscular injection or intravenous drip. Ascaris mostly comes from biliary tract. The insect repellent can be oral albendazole or mebendazole. Appropriate use of anti-infective drugs in patients with fever. ERCP has the functions of diagnosis and deinsectization. Patients with acute suppurative cholangitis, liver abscess and hemorrhagic necrotizing pancreatitis need surgical treatment.

3. Ascaris intestinal obstruction

Fasting, gastrointestinal decompression, spasmolysis and analgesia, rehydration, correction of dehydration and acidosis, taking 60ml of soybean oil and peanut oil can relieve ascaris. After abdominal pain is relieved, deworming is performed. Patients with intestinal necrosis, perforation, peritonitis and complete intestinal obstruction should be operated in time.

[Prognosis]

[prevention]

1. Pay attention to food hygiene, do not eat unclean cold food, and eat raw vegetables and fruits after washing.

2. Develop good hygiene habits and don't urinate anywhere. The transmission route of ascaris lumbricoides is that the eggs excreted by ascaris lumbricoides are excreted with feces, thus polluting the surrounding environment and vegetables and fruits. Once swallowed, it will become infected. Wash your hands before and after meals and cut your nails frequently. Children should not suck their fingers.

Ascariasis is one of the most common intestinal parasitic diseases infected by swallowing ascaris eggs. Its clinical manifestations are fever, cough, itchy skin, paroxysmal pain in the upper abdomen or navel, occasional vomiting or diarrhea, grinding teeth during sleep, and annular insect spots with light pigments on the face. Ascaris also has the characteristics of attacking and escaping, and can wander around, leading to various complications, such as biliary ascariasis.

A mature female ascaris lumbricoides is parasitic in human small intestine, which can lay as many as 200,000 eggs every day. However, these eggs cannot mature in human body, and must be excreted with feces to mature in vitro. Ascaris eggs are very resistant to the external environment and can even survive in the soil for 3-5 years. When people eat vegetables contaminated with eggs and drink raw water, they may swallow live ascaris eggs. This mature ascaris egg comes out of the shell in the human small intestine and gradually develops into strips of ascaris. Ascaris is parasitic in human body, and its life span is about one year.

Ascariasis is quite common in China, with more children in rural areas than adults, more than cities, and the infection rate can reach more than 85%.

Some people mistakenly believe that there should be ascaris parasitism in human body, which is called "digestive worm". It seems that ascaris parasitism can help digestion In fact, ascaris lumbricoides is parasitic, which has many hazards to human body:

1. Ascaris larvae come out of eggs, invade intestinal mucosal blood vessels, enter portal vein, pass through liver, heart, alveoli, trachea and larynx, re-swallow into small intestine, and then formally develop into adults. In this process, if a large number of ascaris larvae pass through the lungs, it can cause patients to have fever, cough and shadows in the lungs, which is called allergic pneumonia. If ascaris lumbricoides larvae go astray and enter the eyes, it may lead to blindness; Entering the brain may lead to epilepsy.

2. Ascaris parasitic in human body will cause malnutrition in patients, especially when it is parasitic in large quantities. The patient is sallow and emaciated, with poor appetite and frequent insomnia. Children often grind their teeth when they sleep at night.

3. Ascaris has the habit of drilling holes. Ascaris can enter the biliary tract when taking anthelmintics, or when there is fever and diarrhea, causing biliary ascariasis. Ascaris may cause intestinal obstruction and so on.

Ascaris parasitism has caused a lot of harm to human body, so ascariasis should not be taken lightly.

To diagnose ascariasis, as long as the stool is tested, if there are ascariasis eggs in it, it can be diagnosed as ascariasis.

There are many drugs for treating ascariasis. In recent years, there have been many new drugs with high curative effect and little side effects, such as levamisole, mebendazole and thiamisole. People with ascariasis can take these drugs under the guidance of a doctor. Some people get rid of a lot of roundworms after taking medicine, but they still can't be cured. Therefore, the key is to prevent the reinfection of ascaris lumbricoides, and the key is to control the food hygiene. Vegetables should be washed and cooked, melons and fruits should be washed and peeled, do not drink raw water, and wash your hands before and after meals. It is also important to cut your nails often, because the dirt under your nails often contains a lot of ascaris eggs.

Two methods of expelling ascaris lumbricoides

Take pomegranate peel 15g, clean it, put it in a pot, add 500g of water, and fry the concentrated juice for about half a bowl. Take it on an empty stomach in the morning, which has special effect on expelling ascaris.

2 tablespoons vinegar, 6 hours 1 time, for 2 days, can drive ascaris.

How does Ascaris enter the human body?

Ascariasis is the most common parasitic disease of water deer, and the prevalence rate in rural areas is higher than that in cities. After being hatched and swallowed, ascaris lumbricoides is mostly killed by gastric acid, and some of them enter the small intestine, where they develop into adults and lay eggs. There are a large number of eggs in female ascaris. Each female ascaris contains more than 20 million eggs, and about 200,000 eggs pass through human feces every day. Eggs are widely distributed in toilets, drying pits and soil after being dried. Ascaris is spread in vegetables, food, water and living environment through fertilization, flying dust and being carried by flies, cockroaches, hunters, chickens and dogs. Bagua can survive in soil 1-2 years, or even longer. The early human body mainly passed through the following channels: 1. Food infection is mainly caused by eating lettuce and fruit with eggs, or eating food contaminated by flies and dust with ascaris eggs. 2, dealing with the sexual behavior of infected children, like to touch some fresh things in the east, grasp at home, and like to play in the field, ascaris eggs are easy to get stuck in your hands and nails. Moreover, it is not easy for children to wash their hands before and after meals. Some infants have fast fingers, and ascaris eggs are easy to bring into their mouths, so there are more chances of getting ascariasis than adults. 3. Drinking water pollutes some rural drinking water or pond water, which is easily polluted by insect hatching. Some rural children drink raw water quickly, so this is also a major route of infection. 4. Ascaris eggs in the dust of respiratory tract infection can be inhaled into the respiratory tract and then swallowed into the digestive tract to infect the human body. A survey abroad found that 3.2% of children have ascaris eggs in their noses. Early-born eggs must be left in the soil as worms with larvae and become infectious eggs, and ascaris will remain.

Harm of Ascaris to Human Body

The terrible thing about ascaris lumbricoides is that ascaris lumbricoides eggs with larvae do not grow and develop directly in the intestine after being swallowed into human body, but after the eggs become larvae, they pass through the blood circulation of human body, pass through important organs such as heart and lungs, and then return to the intestine to develop into adults. The roaming and development of ascaris lumbricoides in human body will cause serious harm to society.

1. After a large number of Ascaris eggs are introduced into larva migrans in a short time, 8-9 days later, larvae enter alveoli, which may cause fever, cough harmony, asthma, urticaria and so on. In severe cases, there is shortness of breath or blood in sputum, and eosinophils in blood increase significantly. The course of disease is short, and most of them recover completely in about 2 weeks. Larvae can also invade the liver, brain, eyes and other organs, causing damage to the corresponding organs, such as hepatomegaly, epilepsy, eyelid edema and so on.

2. Symptoms caused by adults Mildly infected people have no obvious symptoms, while severely punished people cause malnutrition, emaciation, polyphagia, pica and developmental disorders. It is often accompanied by paroxysmal pain in the upper part or around the umbilicus, which can be relieved by itself and has nothing to do with diet.

3, biliary ascaris lumbricoides has the characteristics of liking to drill holes, and will drill a hole when stimulated by drugs, humidity or other factors. If you drill into the biliary tract, it will stimulate the sphincter of the common bile duct to have a strong convulsion, and the right upper abdomen will have severe pain, often accompanied by vomiting, and sometimes it will spit out ascaris. Physical examination showed only mild tenderness in the right upper abdomen, and abdominal signs were inconsistent with abdominal pain. Abdominal pain will be relieved when ascaris lumbricoides quits.

4. The incidence of ascaris intestinal infarction is second only to biliary ascariasis. It is caused by intestinal spasm caused by ascaris lumbricoides blocking the intestinal cavity or ascaris toxin stimulation. It is characterized by severe abdominal pain, accompanied by vomiting, and often spits out bile or ascaris. Abdominal distension is obvious, and abdominal mass or rope feeling can be felt. If the treatment is not timely, intestinal necrosis may occur due to blocked blood circulation in the intestinal wall; Intestinal perforation and secondary peritonitis. Severe vomiting may lead to electrolyte disorder. 5. Other ascaris can also drill into the appendix or liver, leading to ascaris appendicitis or "liver abscess". Coma patients, ascaris will drill into the trachea from the throat, causing suffocation. The diagnosis of ascariasis is mainly based on finding eggs in feces or excreting adults in feces. As for the white spots on the face, such as white spots under nails and night grinding teeth, they can't be used as the basis for diagnosing ascariasis.

What is the secret of treating ascariasis?

I often hear some parents say that their children ate pesticides, but there was no roundworm. How should we treat ascariasis?

1, rational drug selection

(1) mebendazole is a broad-spectrum insect repellent. At present, mebendazole is the main component of commonly used insect repellent, so it is not necessary to avoid oil and have an empty stomach when taking it.

(2) Piperazine citrate (Quyuling), its function is to paralyze the muscles of Ascaris lumbricoides, make Ascaris lumbricoides lose their mobility, and finally be excreted with feces. 0. 15g per kilogram of body weight daily, once before going to bed, for 2 days. 2. Judge whether the ascaris lumbricoides has been completely discharged, and check the stool again after taking the medicine for 7- 10 days. If no eggs are found, the worms are completely repelled. Don't think that after eating 1-2 days, you can't find eggs in your stool and think that the ascaris has been excreted. Because the eggs attached to the intestinal wall cannot be completely excreted within 1-2 days, it takes 7- 10 days to be completely excreted.

The above is the key to thoroughly treat ascariasis. In addition, we often encounter such a situation in clinic. Some children may be intestinal ascariasis according to clinical symptoms, but stool examination can't find eggs. Why? We say that stool examination only selects a piece the size of mung bean from a stool specimen for smear examination. If no eggs are found, the possibility of ascariasis cannot be completely ruled out. If eggs can be found through the concentration of fecal sediment, the positive rate can be greatly improved.

What is ascariasis? How to treat it?

Ascaris is the most common intestinal parasite in human body, and the infection rate in children is the highest. Its main manifestations are poor appetite, abdominal pain, or diarrhea and constipation, which may even cause malnutrition, anemia and mental retardation in children. Due to the stimulation of toxins, children may have symptoms such as anxiety, irritability, panic and grinding teeth, and even cause serious complications such as ascaris intestinal obstruction, biliary ascariasis, ascaris appendicitis, peritonitis and allergic pneumonia. Therefore, children's ascariasis should be examined and treated in time. There are many kinds of drugs to treat ascariasis in children, such as Quyiling and Changchongqing. Traditional Chinese medicines include gentleman, pumpkin seed and dark plum, but they should be used under the guidance of a doctor. Another method is to take 9g of Zanthoxylum bungeanum, impurities and seeds of Zanthoxylum bungeanum, and sesame oil 120g, put them in a pot and heat them, then pour Zanthoxylum bungeanum into the oil and fry them until they are slightly burnt, and cease fire. After cooling, filter out the pepper. If you can't take it once, continue taking it after 2-3 hours. It can be used for treating intestinal obstruction caused by ascaris lumbricoides in children. Abdominal pain is obviously relieved 2 hours after taking it, and ascaris lumbricoides is automatically discharged after half a day.

How to prevent ascariasis?

First of all, we should understand how the human body is infected with ascariasis. Ascaris parasitized in human body excretes a large number of eggs from feces every day. The newly discharged eggs are not contagious, and under appropriate conditions, they become infectious eggs and spread in food, water and living environment. It can survive in soil for 1 ~ 5 years. These infectious ascaris eggs will enter the human body in many ways. For example, children may be infected by eating contaminated food such as lettuce and fruit with eggs; It is also possible that children are infected by the pollution of eggs, because children often play on the ground, touch their hands everywhere, and do not wash their hands before and after meals; Egg pollution of water source is also one of the ways to infect ascaris lumbricoides. After children are infected with Ascaris lumbricoides, Ascaris lumbricoides stimulates the intestinal wall, secretes toxins and consumes nutrients, thus affecting children's growth and development. Therefore, prevention should be given priority to children's ascariasis. The method is to prevent eggs from entering the human body. Ascaris usually dies within 1 ~ 2 years. That is to say, if infected with ascaris lumbricoides, 1 ~ 2 years later, it can be discharged by itself without any treatment. On the other hand, although ascariasis has been effectively treated, if we do not pay attention to hygiene, the eggs will re-enter the human body and develop into adults in the intestine after two months. Therefore, it is very important to prevent primary infection and reinfection. Educate children to develop good hygiene habits, do not eat raw fruits and vegetables, wash their hands before and after meals, often cut their nails and do not suck their fingers. In addition, we must eliminate flies and cockroaches, do a good job in manure management, do a good job in environmental sanitation, and prevent eggs from entering the human body.

How does Ascaris enter the human body?

Ascaris adults generally live in the small intestine. Each female lays about 200,000 eggs at a time, and these eggs are excreted with feces. Under suitable conditions, fertilized eggs gradually become infectious eggs, which are eaten by people in various ways, shelled in the small intestine, become larvae, enter the blood stream through the intestinal wall, travel long distances, migrate to the lungs, enter the alveoli through microvessels, retrograde up the bronchial tree, reach the throat, be swallowed by people, and settle in the small intestine through the stomach. It takes about 60 ~ 75 days from the time when eggs enter the human body to the time when adults lay eggs. The migration of larvae was not smooth, and some larvae were eliminated in the gastrointestinal tract.

What are the manifestations of ascariasis?

Ascaris lives in human small intestine. Because the activity of ascaris stimulates the intestinal wall, children often have abdominal pain, mostly around the navel. Pain is irregular, and they like to rub it when it hurts. Because many insects compete with children for nutrition in the intestine, children are undernourished, which affects their growth and development and can lead to malnutrition and anemia. Due to the influence of ascaris toxin and metabolites, children's appetite is poor, and some children have partial eclipse or heteroeclipse. Children like to eat inedible things such as cinder and wall ash. Some children have low fever, irritability, grinding their teeth and are easily frightened. When the larvae migrate, there may be allergic phenomena such as cough, chest pain, asthma, dyspnea, elevated body temperature, itchy skin and eosinophilia in the blood. Intestinal adults can cause complications, such as ascaris intestinal obstruction, biliary ascariasis, ascaris appendicitis and ascaris peritonitis.

How can I know that there is ascaris in my baby's intestine?

Many parents pay special attention to the insect spots on their children's faces (pityriasis simplex), the green spots on their eyes, the white spots on their nails and the millet spots on the inside of their lips. In fact, these local changes have little to do with intestinal ascariasis, and it is not possible to determine that their children have intestinal ascariasis only by these changes. The most reliable evidence is that the child has recently discharged or vomited ascaris. If you don't have a history of expelling ascaris or spitting ascaris, you should have a stool microscopic examination. If there are ascaris eggs, even if there is only one, make sure that there are ascaris in the child's intestines. However, ascaris eggs can not be detected once or twice, and the existence of intestinal ascaris can not be denied.

How to control ascariasis

Ascariasis is easy to cure, but difficult to prevent. A good treatment is a high-quality insect repellent with good curative effect and few side effects. Difficult to prevent means that ascaris eggs can enter people's intestines through many ways, such as contaminated food, contaminated hands, polluted water sources, etc., which can all cause infection. Therefore, it is very important to prevent primary infection and repeated infection. Therefore, a lot of work should be done to eliminate ascariasis, such as killing flies and cockroaches, managing feces, water and food, educating children not to defecate anywhere, washing their hands before and after meals, often cutting their nails, not sucking their fingers, cleaning raw fruits and vegetables or soaking them in disinfectant. If we can do this seriously, we won't be infected with ascaris eggs again.

Selection of drugs for expelling ascaris: ① Albendazole (Smith Enterotoxigenic Clear), 200mg per tablet, 2 tablets each time (this drug cannot be taken by infants for expelling ascaris). The cure rate was 96%, and the negative rate of eggs was 100%. There are two dosage forms of mebendazole: tablets, each tablet100 mg; Anle oral suspension, 30 ml per bottle, 20 mg per ml. The administration method is 200 mg per day, 1 time, or 100 mg per time, twice a day for 3 days. The cure rate was 87% ~ 100%, and the negative rate of eggs was 90% ~ 100%.

How to treat ascariasis with traditional Chinese medicine

(1) General ascariasis

It is characterized by recurrent paroxysmal abdominal pain around umbilicus or recurrent hidden pain around umbilicus, like to rub, eat more or less, or eat foreign bodies, stay up at night, grind teeth, dig nose, bite nails, have a history of vomiting and defecation, and even eat dirt, raw rice charcoal ash and other things. Most children have pale white spots on the face, blue spots on the sclera, or fine punctate protrusions under the lips, pale red tongue, white fur and thin pulse. Peripheral blood tests showed that eosinophils increased. Treatment: dispel contraction and strengthen the spleen. Zhuichong Pill is decocted with Sijunzi Decoction, which is used for medicine: Radix Codonopsis, Atractylodis Rhizoma, Poria, Glycyrrhrizae Radix, Areca catechu, Wan Lei Pill, Moria Goddess Skin, Zaocys, Radix Aucklandiae, Herba Artemisiae Scopariae and Gleditsia sinensis.

(2) Arrogance syndrome

There is usually a history of vomiting or defecation, and sometimes there is umbilical and abdominal pain, sudden and severe abdominal pain, abdominal mass swelling, or palpable mass, vomiting, constipation, pale face and pulse. Treatment: Anquan moistens dryness and repels insects. The recipe is to drink oil pepper, that is, 100 ml of soybean oil and 4 ~ 6 grams of fried Sichuan pepper, and drink oil from Sichuan pepper in a burnt degree, and drink it up in 1 ~ 2 times.

(3) syncope

There is a history of ascaris lumbricoides and common symptoms of ascaris lumbricoides, such as sudden colic in the upper abdomen or left abdomen, bending back, cold sweat in limbs, vomiting and frequent vomiting of cricket, intermittent abdominal pain, which can be as sudden as normal people, with severe abdominal pain lasting, sometimes mild and sometimes severe, or chills and fever, yellow and greasy fur, and slippery pulse. The treatment is divided into three steps: ① Anquan. (2) expel the clam. 3 adjust. Prescription: take 20 ~ 30ml old rice vinegar orally, and take it again after half an hour. After the pain is relieved, conventional anthelmintic treatment is carried out, and the treatment method is cockroach control and anthelmintic treatment. The formula is Jiawei Mume Pill, which is made of Mume Fructus, Zanthoxylum bungeanum, Cortex Phellodendri, Areca catechu, Moria Goddess, Zingiberis Rhizoma and Asari. Decoct with water. Ascaris is discharged, and abdominal pain is relieved. Yi 'an can tonify the spleen and stomach, and use five kinds of powder: Radix Codonopsis, Atractylodis Rhizoma, Poria, Pericarpium Citri Tangerinae and Radix Glycyrrhizae. Decoct with water, three times a day.

Do children have ascariasis fever?

Ascariasis is more common in children, especially preschool children. Ascaris lumbricoides is a large nematode similar to earthworm, which is parasitic in the upper segment of small intestine. After people take infected eggs orally, their larvae hatch in the upper part of the small intestine, migrate in the body and finally develop into adults in the small intestine.

In the early stage of ascariasis, when the larvae migrate in the body, the larvae pass through the lungs, which may cause inflammatory reaction because of their metabolites or the death of the larvae themselves. At this time, the child may have low fever, paroxysmal cough and foreign body sensation in the pharynx. When adults are parasitic in the small intestine, most children may have no clinical symptoms, and some children may have intestinal dysfunction such as abdominal pain, but generally have no systemic symptoms such as fever.

Ascaris parasitized in the small intestine is usually in a quiet state, but if it is stimulated by fever, diarrhea and so on, it can cause commotion. Because ascaris lumbricoides has the habit of drilling holes, it can produce various complications. Ascaris can cause acute cholecystitis, acute cholangitis and even acute pancreatitis or liver abscess when it enters the biliary tract. When ascaris lumbricoides causes biliary complications, symptoms such as high fever and abdominal pain may occur due to secondary infection. When a large number of ascaris entangles in the small intestine, it can cause intestinal obstruction. At this time, in addition to severe abdominal pain, children may generally have a fever. Ascaris can cause ascaris peritonitis, abdominal pain and fever when it enters abdominal cavity through perforation of small intestine or appendix.

In short, children with intestinal ascariasis generally have no fever symptoms. When the larva migrates to the lungs, it may have fever due to the stimulation of metabolites, but the fever symptoms are generally mild, mostly low-grade. Only when there are various complications, due to secondary infection, will it cause high fever. Therefore, when a child suddenly has abdominal pain and high fever, parents must seek medical treatment in time.

Does Qu Juanling's poisoning affect children's intellectual development?

Quyuanling is a widely used drug for expelling intestinal worms, which has a good effect on expelling roundworms and pinworms. It is cheap and less toxic, but it can also be poisoned by taking too much by mistake. Children with kidney disease or sensitive to the drug may also have serious reactions when treated with therapeutic doses.

Qujunling poisoning usually appears symptoms 7-8 hours after taking medicine, and some people appear symptoms 2 days later. Sick children have symptoms such as nausea, vomiting, abdominal pain and diarrhea, which can also lead to toxic liver disease, headache, dizziness, listlessness, hearing loss, blurred vision, uncoordinated movements, unstable gait, dancing-like movements, tremor and memory loss. Severe cases can cause toxic psychosis, convulsion, lethargy, coma, paralysis and death from respiratory paralysis. In addition, hematuria and proteinuria may occur. Children who are sensitive to this drug may have severe reactions such as high fever, nausea, vomiting, abdominal pain, pallor, cyanosis, cold limbs, asthma attack, decreased pulse and decreased blood pressure.

Poisoning by Qu Yiling can cause memory loss, toxic psychosis, coma, convulsion and respiratory paralysis, which shows that the disease has a great influence on the central nervous system of the brain. If it cannot be rescued in time, the impact on children's intelligence can be imagined. In addition, it will also cause hearing loss and blurred vision, which will indirectly affect children's intellectual development. Therefore, children should follow the doctor's advice when taking Qutongling, and the dosage should not be too large at one time, and there should be a certain time interval between two drugs to prevent poisoning.

Children poisoned by ascaris lumbricoides should be sent to the hospital immediately, first induce vomiting, then gastric lavage and then catharsis. Oxygen should be given to prevent convulsion and coma, artificial respirator should be used to assist breathing when respiratory paralysis occurs, and attention should be paid to protecting liver and kidney function. Children who are allergic to this drug should immediately use hormones to prevent allergies.
