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.

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.
Tetralogy of Fallot Clinical Symptoms
The clinical manifestations of Tetralogy of Fallot include cyanosis, with cyanosis being the primary symptom. The severity of cyanosis is related to the extent of pulmonary stenosis and is commonly seen in areas rich in capillaries, such as the lips, fingertips, nail beds, and conjunctiva, where it appears more pronounced during physical activity or crying. Secondly, the squatting symptom is observed; children may show squatting behavior during walking or playing, often squatting down voluntarily for a moment. During squatting, the flexion of the lower limbs reduces the venous return to the heart, lightening the cardiac load and decreasing the right-to-left shunting, thereby alleviating hypoxia. Thirdly, clubbing of the fingers occurs due to long-term hypoxia, leading to hypertrophic growth at the fingertip and toe ends. Fourthly, paroxysmal hypoxic attacks occur.
What should I do about baby measles?
The main treatments for measles in infants include symptomatic treatment, enhanced care, and prevention of complications. Children with measles should rest in bed, maintain a suitable indoor temperature and air circulation, avoid strong light exposure, and ensure cleanliness of the skin, eyes, and mouth. Encourage them to drink plenty of water and provide easily digestible, nutritionally rich food. For fever, a small dose of antipyretic can be used as appropriate, but rapid fever reduction should be avoided, especially during the initial diagnosis period. Cough may be treated with nebulization and cough suppressants. It is necessary to supplement vitamins. Appropriate treatments should be given for complications, and antibiotics should be provided for secondary infections.
Early symptoms of measles in children
The initial manifestations of measles include: First, fever usually moderate or higher, with varying patterns. Second, symptoms of upper respiratory tract inflammation and conjunctivitis. Along with the fever, symptoms such as cough, sneezing, throat congestion, acute upper respiratory infections, conjunctival congestion, tearing, and photophobia can appear. Third, measles mucosal spots, also known as Koplik's spots, are an early specific sign of measles. They usually appear one to two days before the rash, initially located on the buccal mucosa opposite the lower molars as gray-white spots with a diameter of 0.5-1mm, surrounded by a red halo. They rapidly increase in number, extending over the entire buccal and lip mucosa, and may merge. They disappear one to two days after the rash appears. Fourth, other symptoms include general discomfort, decreased appetite, lethargy, and may also include vomiting and diarrhea.
Intestinal intussusception described by ultrasound.
The appearance of intussusception under ultrasound shows concentric or target ring-shaped mass images on a transverse section scan, and a sleeve sign on a longitudinal section scan. For an ultrasound-guided hydrostatic reduction, a balloon is inserted through the anus and inflated, connecting a T-tube to a Foley catheter with a side tube connected to a sphygmomanometer to monitor water pressure. Isotonic saline at a temperature of thirty to forty degrees is injected, and the target ring-shaped mass image can be seen retracting to the ileocecal region. The disappearance of the concentric circles or sleeve sign under ultrasound indicates the completion of this therapeutic diagnosis.
How to treat intussusception in infants
The treatment of intussusception mainly includes non-surgical and surgical methods. The non-surgical method involves enema treatment. Within 48 hours of the onset of intussusception, if the overall condition is good, there is no abdominal distension, no apparent dehydration, and no electrolyte disorders, ultrasound-guided hydrostatic enema, air enema, or barium enema can be performed. If the intussusception lasts more than 48 to 72 hours, or if the duration is shorter but the condition is severe, with intestinal necrosis or perforation, surgical treatment is required.
What to do about enteritis in a one-year-old baby
Most cases of enteritis are due to viral infections. The principles of treatment primarily involve diet adjustment, prevention and correction of dehydration, rational use of medication and enhanced nursing care, and preventing complications such as dehydration. Treatment of diarrhea varies with different stages; during the acute phase, it is important to maintain a balance of water and electrolytes, while prolonged and chronic diarrhea requires attention to intestinal flora imbalance and dietary adjustments. A minority of diarrhea cases are caused by bacterial infections, and if there is clear evidence of bacterial infection, appropriate antimicrobial drugs should be used.
Phenylketonuria lacks what enzyme?
Phenylketonuria is an autosomal recessive genetic disorder caused by a mutation in the phenylalanine hydroxylase gene, which leads to reduced enzyme activity and the accumulation of phenylalanine and its metabolites in the body, resulting in disease. Phenylketonuria is the most common congenital disorder of amino acid metabolism, clinically characterized by developmental delays in intelligence, light pigmentation of the skin and hair, and a mousey odor to the urine. It is often due to a deficiency of phenylalanine hydroxylase.
