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.

Caused by infantile intussusception
Intussusception is divided into primary and secondary types, with 95% being primary cases, most commonly seen in infants and young children. This is due to the fact that the mesentery of the ileocecal part in infants and young children is not yet fully fixed and has a greater degree of mobility, which are structural factors that facilitate the occurrence of intussusception. The remaining 5% are secondary cases generally occurring in older children, where the affected intestines often have a clear organic cause, such as a Meckel's diverticulum turning into the ileal lumen, serving as the starting point for intussusception. Other causes like intestinal polyps, tumors, duplications, or abdominal purpura can cause the intestinal wall to swell and thicken, which can also trigger intussusception.
Can Tetralogy of Fallot be cured?
With the continuous improvement of surgical techniques, the cure rate for total corrective surgery for Tetralogy of Fallot is increasing, and the mortality rate is continuously decreasing. Mild cases may have the opportunity to undergo a one-stage corrective surgery between the ages of five and nine. However, for patients with significant clinical symptoms, palliative surgery should be performed within six months after birth. Once the general condition improves and pulmonary vasculature develops, they can proceed with the corrective surgery. Overall, the cure rate for Tetralogy of Fallot is continuously improving.
Is infant intussusception dangerous?
Intussusception is a life-threatening emergency, and its reduction is an urgent treatment measure that should be performed immediately once confirmed. It is a common acute abdomen disease in infants and young children. Initially, the general condition may be good, but as the disease progresses, the condition worsens, leading to systemic deterioration, complications such as intestinal necrosis or peritonitis, and severe symptoms of poisoning such as severe dehydration, high fever, lethargy, coma, and shock.
Tetralogy of Fallot cyanosis cause
Tetralogy of Fallot, due to a ventricular septal defect combined with right ventricular outflow tract narrowing, can display left-to-right, bidirectional, or even right-to-left shunting at the ventricular level. Patients with mild pulmonary stenosis can have left-to-right shunting and usually do not exhibit cyanosis. However, when the pulmonary stenosis is severe, significant right-to-left shunting occurs, and clinically apparent cyanosis becomes evident. Cyanosis is commonly observed in areas rich in capillaries and superficial tissues, such as the lips, fingertips, nail beds, and bulbar conjunctiva.
Infant intussusception typical symptoms
The typical clinical manifestations of intussusception are as follows: Firstly, abdominal pain, which occurs in paroxysmal, regular episodes, characterized by sudden onset of severe colicky pain. The child appears restless and cries, with knees drawn to the abdomen, pale complexion, and relief coming after several minutes or longer; the pain reoccurs every ten to twenty minutes. Secondly, vomiting is an early symptom, initially reflexive containing milk curds or food residues, later possibly containing bile, and in the late stage, fecal-like liquid may be vomited. Thirdly, bloody stools are a significant symptom, appearing within the first few hours; initially, stools may appear normal, later becoming scanty or absent. In about 85% of cases, a jam-like mucousy bloody stool is passed within six to twelve hours of onset, or bloody stools are found upon rectal examination. Fourthly, abdominal mass is often found in the right upper quadrant just below the ribs, where a slight movable intussusception mass can be palpated, resembling a sausage.
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.
