About me
Since graduating in 2003, I have been working in pediatric clinical practice and have extensive experience in this field. In 2012, I completed a training program in the Pediatric Intensive Care Unit (PICU) at the Children's Hospital in Hunan Province, focusing on respiratory management and mechanical ventilation for critically ill children, as well as the treatment of septic shock.
Proficient in diseases
Specializing in pediatric critical care, dedicated to rescuing and treating children with critical conditions such as respiratory failure, heart failure, shock, poisoning, etc., and has been involved in the treatment of severe cases of hand, foot, and mouth disease multiple times.

Tetralogy of Fallot symptoms in infants
Infants with Tetralogy of Fallot often exhibit the following symptoms: First, cyanosis, which is most apparent in areas rich in capillaries such as the lips, fingernail beds, and conjunctiva. Cyanosis tends to worsen gradually during crying, emotional distress, or physical exertion. Second, squatting symptoms; infants who cannot walk often prefer to be held by adults in a flexed position of both lower limbs, reducing venous return and easing the cardiac workload. Older children often exhibit squatting during activities such as walking and playing, frequently squatting down momentarily. Third, infants in a prolonged hypoxic environment may develop clubbing, characterized by the enlargement of the fingertips and toes, with capillary expansion and proliferation, resembling drumsticks. Fourth, episodic hypoxia occurs predominantly in infants, triggered by feeding, crying, or emotional distress, manifesting as episodes of respiratory difficulty, with severe cases leading to sudden fainting or convulsions.
Is intussusception in children serious?
Intussusception is a life-threatening emergency, and its reduction is an urgent treatment measure that should be performed immediately once diagnosed. In the early stages, the child generally appears healthy, with normal body temperature and no obvious symptoms of poisoning. However, as the condition progresses and the duration of the intussusception increases, it can lead to intestinal necrosis or peritonitis, causing a deterioration in the overall condition. Commonly, severe dehydration, high fever, coma, shock, and other serious symptoms of poisoning may occur.
Tetralogy of Fallot is what?
Tetralogy of Fallot is the most common cyanotic congenital heart disease in infants, accounting for about twelve percent of all congenital heart diseases. It was thoroughly described by the French physician Fallot in 1888, which is how it got its name. Tetralogy of Fallot consists of four cardiac malformations: first, obstruction of the right ventricular outflow tract; second, ventricular septal defect; third, overriding aorta; fourth, right ventricular hypertrophy.
What are the symptoms of iron deficiency anemia in children?
Iron deficiency anemia can manifest as: 1. Gradual pallor of the skin and mucous membranes, especially noticeable on the lips, oral mucosa, and nail beds. Older children may experience dizziness, darkening before the eyes, and tinnitus. Additionally, anemia can lead to extramedullary hematopoiesis, and enlargement of the liver, spleen, and lymph nodes can occur. The younger the age and the longer the duration of the disease, the more severe the anemia and the more prominent the enlargement of the liver and spleen. 2. In terms of gastrointestinal tract: reduced appetite, pica, vomiting, diarrhea, and stomatitis may occur. 3. Nervous system manifestations include: restlessness or lethargy, lack of concentration, reduced memory, and intelligence often lower than peers of the same age. 4. Cardiovascular system: an increased heart rate may be observed, and in severe cases, cardiac enlargement and even heart failure can occur. 5. Immune system: Iron deficiency can affect hematopoietic function, often leading to reduced cell-mediated immune function and combined infections.
Why does intussusception cause bloody stool?
Once intussusception occurs, only a small portion of the small intestine intussusceptions can reset themselves. Due to the continuous spasm of the sheathed intestinal tract, microcirculatory disorders occur in the intussuscepted segment. Initially, venous blood flow is obstructed, leading to tissue congestion and edema, venous varicosity, and mucosal cells secrete a large amount of mucus into the intestinal lumen, which mixes with blood and feces to form a jam-like jelly substance that is expelled. The intestinal wall becomes edematous, and the obstruction of venous return worsens, affecting the arteries, resulting in insufficient blood supply, and leading to systemic toxic symptoms. In severe cases, intestinal perforation and peritonitis can occur.
Treatment methods for children's mumps
Mumps currently has no specific antiviral treatment; treatment is primarily symptomatic. It is important to maintain oral cleanliness, provide a light diet, avoid acidic foods, and drink plenty of water. For symptoms such as high fever and headache, or concurrent inflammation of the testicles, antipyretic analgesics should be administered. Traditional Chinese medicine treatments often involve clearing heat and detoxifying, softening hardness and relieving pain. Common treatments include modified Puji Xiaodu Yin taken orally or Qing Dai mixed with vinegar applied topically. Under medical guidance, ribavirin can be used in the early stages of the disease, administered intravenously at a dose of 10 to 15 milligrams per kilogram of body weight per day, with a treatment course of 5 to 7 days. Corticosteroids may be used for severe cases for a short course of three to five days.
Is intussusception in children serious?
Intussusception is a life-threatening emergency, and its reduction is an urgent medical treatment that must be performed immediately once diagnosed. Generally, in the early stages of intussusception, the general condition is still good, with normal body temperature and no symptoms of systemic toxicity. As time progresses, the condition worsens, and there may be necrosis of the intestines or peritonitis, with overall health deteriorating. Common severe symptoms include dehydration, high fever, lethargy, coma, and shock from toxicity.
What position should be adopted when Tetralogy of Fallot is hypoxic?
Treatment of hypoxic episodes in Tetralogy of Fallot: For mild cases, assuming the knee-chest position can alleviate symptoms. Severe cases require immediate oxygen administration and relevant drug therapy. Routinely, it is important to actively eliminate factors that trigger hypoxic episodes, such as anemia and infections, and maintain the child's tranquility. If the above treatments do not effectively control the episodes, emergency surgical intervention for repair or definitive treatment should be considered.
Symptoms of newborn enteritis
Neonatal enteritis can present with diarrhea and bloody stools, initially as watery stools, and in severe cases, may appear as bloody stools, resembling fresh blood, jam-like consistency, and black feces. The affected infants often exhibit vomiting, with the vomitus appearing coffee-colored or containing bile. Neonatal enteritis can also present with abdominal distension, or reduced bowel sounds, initially characterized by delayed gastric emptying and gastric retention, followed by abdominal bloating. In severe cases, the abdomen may become drum-like with diminished or even absent bowel sounds. Enteritis may also be accompanied by systemic symptoms, often presenting as poor responsiveness, lethargy, refusal to eat, and in severe cases, pale or grayish complexion, cold limbs, shock, acidosis, and worsening jaundice.
Management of Hypoxic Episodes in Children with Tetralogy of Fallot
In the treatment of hypoxic episodes in children with Tetralogy of Fallot, mild cases can be alleviated by positioning the child in a knee-chest position, while severe cases should receive immediate oxygen therapy, along with appropriate medication to correct acidosis. It is important to regularly eliminate factors that may trigger hypoxic episodes, such as anemia and infections, and to maintain a calm environment for the child. If these measures do not effectively control the episodes, emergency surgical repair should be considered.
