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.

Phenylketonuria Clinical Symptoms
Phenylketonuria may appear normal at birth, but symptoms usually start to appear between three to six months, with the symptoms becoming most evident at one year old. These are often manifestations of the nervous system, with prominent developmental delays in intelligence. The IQ is often lower than normal, and there may be abnormal behaviors, minor epileptic seizures, and, in a few children, increased muscle tone and hyperactive tendon reflexes. Due to insufficient melanin synthesis a few months after birth, affected children’s hair color changes from black to yellow, their skin is fair, and skin eczema is relatively common. Due to the elevated excretion of phenylacetic acid in urine and sweat, there is a distinct mouse-like urine smell.
Care for children during epileptic seizures
During an epileptic seizure, it is crucial to control the seizure promptly by using sedative and anticonvulsant medications. While administering these drugs, it is important to closely monitor for consistent breathing. Additionally, during a seizure, it is necessary to ensure that the airway remains clear, provide oxygen, and, if required, use mechanical ventilation to maintain airway patency. Prevent biting injuries to the tongue and position the head to one side so that secretions can flow out of the corner of the mouth, preventing reflux of stomach contents and risk of choking. Protect brain function and vital organs, and prevent cerebral edema. After the seizure has stopped, long-term administration of antiepileptic drugs should be continued to prevent recurrence.
How to relieve itching from baby rash?
Roseola infantum is caused by human herpesvirus infection, primarily characterized by high fever for three to five days. After the fever subsides, a rash appears. The rash, consisting of small, dense red maculopapules, is primarily located on the trunk and face, with fewer occurrences on the limbs. The entire rash appears in one day and gradually fades the following day. The rash does not cause itching, so there is generally no need for special anti-itch medications. The rash usually fades gradually the day after it appears and leaves no scars once it has cleared. The appearance of the rash after the fever subsides indicates that the herpesvirus infection is nearing recovery, requiring no special treatment.
Tetralogy of Fallot in children who prefer squatting is because
Tetralogy of Fallot exhibits squatting symptoms because squatting involves flexing the lower limbs, which reduces the amount of venous return to the heart, thereby decreasing the cardiac workload. At the same time, the arteries of the lower limbs are compressed, increasing systemic vascular resistance, reducing right-to-left shunting, and temporarily alleviating hypoxia symptoms. Infants who cannot walk often prefer to be held with their thighs up, with both lower limbs bent; after they become able to walk, they frequently squat down momentarily during walking or playing.
How many times does a young child get a sudden rash?
Roseola infantum is caused by human herpesvirus types 6 and 7, often manifesting as fever and sudden high fever lasting three to five days. The symptoms and signs are mild, disproportionate to the high fever, with 5%-10% of cases experiencing convulsions. On the third to fifth day of the illness, when the fever suddenly subsides, a scattered rose-colored maculopapular rash appears either simultaneously or slightly later, quickly spreading to the neck and trunk, and resolving within one to two days. This condition occurs in 90% of children under the age of two, although it is occasionally seen in older children and adolescents. Most cases are sporadic, and infection usually results in long-lasting immunity. A second occurrence of the disease is rare.
How many days will pneumatic reduction for intussusception take to recover?
The indications of successful reduction of intussusception by air enema treatment are as follows: First, after the removal of the tube, a large amount of foul-smelling mucousy bloody stool and yellow feces are expelled. Second, the patient quickly falls asleep, no longer cries, and ceases to vomit. Third, the abdomen is soft and flat, with no palpable mass as before. Fourth, after the enema reduction, 0.5-1 grams of activated charcoal is administered orally; if charcoal residue is expelled within six to eight hours, it indicates a successful reduction. However, even after successful reduction, it is necessary to remain under observation in the hospital for two to three days to monitor for any recurrence of the intussusception.
Causes of intussusception in children
The causes of intussusception are divided into primary and secondary types, with 95% being primary, commonly seen in infants and young children. In infants, the mesentery of the ileocecal area is not yet fully fixed and has greater mobility, which is a structural factor prone to intussusception. Secondary cases account for 5%, where intussusception occurs. Some intestines show clear organic changes, such as Meckel's diverticulum, intestinal polyps, intestinal tumors, intestinal duplication anomalies, abdominal purpura, and thickening of the intestinal wall, which can cause intussusception of the intestines. Certain triggers, including dietary changes, viral infections, and diarrhea, can induce intussusception.
What are the symptoms of roseola infantum?
Roseola infantum commonly occurs in infants under one year old, caused by human herpesvirus type 6 infection. It typically presents with very high fever, with temperatures often reaching 39-40 degrees Celsius, and throat congestion. However, the patient generally remains in good condition without obvious symptoms of infection or poisoning. Blood tests are generally normal, indicating a viral infection. Symptomatic treatment is given, and about three to five days later, the temperature abruptly drops. One to two days after the temperature returns to normal, a red, rose-like rash appears, primarily on the head, face, and trunk, consistent with the clinical manifestations of rash following the resolution of the fever.
Tetralogy of Fallot syncope causes
The causes of syncope in Tetralogy of Fallot generally involve episodic hypoxia attacks, which are more common in infants. Triggers include breastfeeding, crying, emotional excitement, anemia, and infections. The symptoms manifest as episodic breathing difficulties, and severe cases can suddenly lead to syncope with convulsions or even death. The underlying reason is the narrowing of the pulmonary artery infundibulum accompanied by muscular spasms, causing obstruction of the pulmonary artery and intensifying cerebral hypoxia. Older children may complain of headaches and dizziness.
How to treat chickenpox in children?
Chickenpox is a self-limiting disease, and when there are no complications, treatment generally involves basic care and symptomatic management. Patients should be isolated, with enhanced nursing care such as frequently changing underwear, trimming the nails of children to prevent scratching, and reducing secondary infections. It is important to maintain good ventilation in the room, provide adequate water and easily digestible food, and use antipruritic agents as appropriate to relieve itching. Antiviral drugs may be appropriately selected, antibiotics can be used for secondary infections, and corticosteroids should not be used.
