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.

Causes of intussusception in children
The etiology of intussusception is divided into primary and secondary types, with 95% being primary, which is common in infants and young children. In infants, the mesentery of the ileocecal region is not yet fully fixed and has a larger degree of mobility, which is a structural factor conducive to the occurrence of intussusception. Secondary cases account for about 5%, often secondary to Meckel's diverticulum, intestinal polyps, intestinal tumors, intestinal duplications, and abdominal purpura causing swelling and thickening of the intestinal wall, which can lead to intussusception. Certain factors may cause a change in the rhythmic movement of the intestines leading to disorder, thereby inducing intussusception, such as changes in diet, viral infections, and diarrhea.
Symptoms and Treatment of Chickenpox in Children
Chickenpox is an acute, contagious, exanthematous disease caused by varicella-zoster virus infection. Before the rash appears, symptoms such as fever, discomfort, and loss of appetite may occur. The fever typically lasts about one day before the rash emerges. The rash initially appears on the head, face, and trunk with a centripetal distribution. The rash can present as macules, papules, vesicles, and crusts all appearing simultaneously. Rashes can also appear on the mucous membranes of the mouth and the genital area. The treatment for chickenpox involves symptomatic and supportive care, and antiviral medications may be used appropriately to protect the skin and prevent scratching.
Symptoms of intussusception in infants
The clinical manifestations of intussusception mainly include abdominal pain, vomiting, bloody stools, and an abdominal mass. The abdominal pain is often spasmodic and regular, manifesting as sudden severe colicky pain. The child appears to be crying and restless, with knees drawn up to the abdomen, pale complexion, and the pain lasts for several minutes or longer but lessens after; it recurs every ten to twenty minutes, accompanied by intestinal movements. Vomiting is an early clinical symptom, initially consisting of milk curds or food residue, and later may include bile and fecal-like liquid. Bloody stool is an important symptom, appearing within the first few hours; initially, the stools can be normal, with about 85% of cases excreting jam-like mucoid bloody stools within six to twelve hours of onset. The abdominal mass is often located in the upper right abdomen below the costal margin, where a slight, tender mass can be palpated.
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.
