Pediatrics
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.

Can chickenpox in children be transmitted to adults?
Chickenpox is a highly contagious exanthematous disease caused by varicella-zoster virus infection. Its clinical characteristics include the successive or simultaneous appearance of papules, vesicles, and crusts on the skin and mucous membranes. Both chickenpox and herpes zoster patients are sources of infection, primarily from those with chickenpox. From one to two days before the onset of the disease until crusting, it is highly contagious, mainly transmitted through airborne droplets and the respiratory tract, or by contact with vesicular fluid. The general population is susceptible, especially pregnant women and people with low immunity, making it possible to transmit to adults.
How to treat neonatal pneumonia?
Neonatal Pneumonia Treatment: 1. Manage the respiratory tract by nebulization inhalation, postural drainage, regular turning and back patting to keep the airway clear and clean the oral and nasal secretions. 2. For those with hypoxemia, provide oxygen therapy, which may include nasal cannula oxygen delivery, masks, or head masks. Mechanical ventilation may be necessary if required. 3. Choose appropriate antibiotics; for bacterial infections, select sensitive antibiotics based on the type of bacteria, while antiviral drugs can be used to support treatment of viral infections. 4. Correct circulatory disturbances and electrolyte balance, control infusion rate to prevent heart failure and pulmonary edema, and ensure the supply of energy and nutrients. Immunoglobulin can be used as appropriate to boost immunity.
Pediatric intussusception should see which department?
Intussusception often occurs in infants and young children, so the main symptoms are vomiting, bloody stools, and abdominal pain. Therefore, the initial consultation is usually in pediatric emergency. When intussusception is suspected as a cause of acute abdomen, the doctor will conduct intestinal tube and abdominal ultrasound examinations. If the ultrasound confirms intussusception, a transfer to pediatric surgery or emergency surgery may be considered for appropriate surgical treatment. Thus, the initial choice for consultation is usually pediatrics, but after a diagnosis is confirmed, treatment should be transferred to pediatric surgery.
What should be paid attention to when children have chickenpox?
Chickenpox is a self-limiting disease, and when there are no complications, treatment generally focuses on symptomatic relief. During illness, isolation should be maintained to prevent infection and enhance care, such as frequently changing underwear, trimming the child's nails, and wearing gloves to prevent scratching. Keep the air well-ventilated, provide sufficient fluids and easily digestible food. If a secondary bacterial infection occurs, antibiotic treatment should be administered. The child should be isolated until all the rash has crusted over.
Why does Tetralogy of Fallot squat?
The primary deformity in Tetralogy of Fallot is the obstruction of the right ventricular outflow, which leads to increased right ventricular pressure and a right-to-left shunt causing cyanosis. When the child squats, the flexion of the lower limbs can reduce the return of blood to the heart, alleviating the burden on the right ventricle. At the same time, it can increase systemic circulation resistance, reducing the right-to-left shunt in the heart, thereby alleviating the child's symptoms of hypoxia.
The reason for squatting in Tetralogy of Fallot
The reason for squatting is that when squatting, the lower limbs are bent, which reduces the amount of blood returning to the heart through the veins, thereby reducing the load on the heart. At the same time, the arteries in the lower limbs are compressed, which increases the resistance in the systemic circulation and reduces the right-to-left shunt volume, allowing temporary relief from hypoxia symptoms. Babies who cannot walk often like to be held by adults in a position that bends the lower limbs to reduce the amount of blood returning to the heart. This frequently occurs during walking and playing, often characterized by brief periods of squatting.
Tetralogy of Fallot's composition and its causes of formation
Tetralogy of Fallot consists of four abnormalities. First, there is a narrowing at the right ventricular outflow, ranging from the entrance of the right ventricular infundibulum to the branches of the left and right pulmonary arteries. Second, there is a ventricular septal defect, characterized by a deficiency around the membranous part that extends towards the outflow. Third, the aorta overrides, where the base of the aorta is enlarged and rotates clockwise to the right, straddling the septal defect. Fourth, right ventricular hypertrophy, which is a secondary lesion.
Can intussusception in children cause fever?
In the early stages of intussusception, the child generally remains in good condition, with normal body temperature and no symptoms of systemic poisoning. As the disease progresses and worsens, complications such as intestinal necrosis or peritonitis may develop, leading to deterioration of the overall condition. At this point, severe dehydration, high fever, lethargy, coma, and shock, among other symptoms of poisoning, can occur. Therefore, fever can indeed appear in the later stages of intussusception.
Tetralogy of Fallot Clinical Characteristics
Tetralogy of Fallot is the most common cyanotic congenital heart disease in infancy, accounting for about 12% of all congenital heart diseases. It is caused by malformations of four heart structures: 1. right ventricular outflow tract obstruction; 2. ventricular septal defect; 3. overriding aorta; 4. right ventricular hypertrophy. Its clinical manifestations may include cyanosis, squatting symptoms, clubbed fingers, and paroxysmal hypoxia attacks. Physical examinations generally show delayed development, a prominent precordial area, and at the second to fourth rib interspace along the left sternal margin, a grade 2 to 3 rough systolic murmur can be heard.
Emergency treatment for cyanosis in Tetralogy of Fallot
During hypoxic attacks of Tetralogy of Fallot, for mild cases, adopting the knee-chest position can provide relief. Severe cases should immediately receive oxygen and be given relevant medication treatment. Normally, attention should be paid to removing factors that cause hypoxic attacks, such as anemia and infections, and keep the child as calm as possible. For cases where hypoxia cannot be effectively controlled through the above measures, emergency surgical repair should be considered.
