[Health Channel/Comprehensive Report] The Central Meteorological Bureau forecast that due to the passage of the front and the cold current, the temperature will drop and be cold on weekends. From Saturday night to Sunday morning, the low temperature in the north of the central part will generally fall at 6 to 7 degrees. Be sure to do a good job of keeping warm.

Xie Zongxue, director of the Pediatric Emergency Department of the Affiliated Hospital of Sun Yat-sen Medical University, emphasized that respiratory infections combined with allergies, combined with low temperature in the environment, can easily lead to severe bronchiolar inflammation or asthma attacks in children. Caregivers must be extra careful and pay more attention to the hygiene protection of young children.

Xie Zongxue posted an article on the Facebook page "Dr. E Pediatric Emergency Room Diary" that more than half of the patients who visited the children's emergency room in the past few days complained of wheezing or shortness of breath. Children older than 2 years have wheezing episodes.

Different from last year, this year due to downgraded epidemic prevention, various respiratory viruses and mycoplasma are prevalent in the community. Coupled with the rapid drop in temperature, bronchioles constrict or accumulate phlegm, which can easily lead to bronchiolar inflammation or wheezing in tracheal attacks.

Xie Zongxue explained that basically asthma is diagnosed in children over 2 years old. If wheezing occurs during breathing under 2 years old, foreign body inhalation should be excluded. Inflammation of the bronchioles, the younger the age, the higher the chance of developing respiratory failure requiring intensive care unit treatment. Because the bronchial smooth muscle is immature, it is obviously not effective for bronchodilators. At present, only pure oxygen can provide a real curative effect, and effective methods are rarely added. Difficult to treat.

Respiratory infection a major trigger of asthma attacks in children

Xie Zongxue pointed out that infection is the most important trigger factor for asthmatic attacks in children, and the decrease in temperature is only a cofactor.

Without respiratory tract infection, no matter how low the temperature is, it is not easy to cause children's tracheal attacks. However, if there is a respiratory tract infection, as long as the temperature changes slightly, it is easy for children who already have allergies to suddenly have asthma attacks.

Xie Zongxue mentioned that recently there were several cases of children under the age of 2 who suffered from bronchiolar inflammation after being admitted to the general ward, panting to the point of respiratory failure, and finally had to be transferred to the children's intensive care unit for temporary respirator support treatment, reminding parents to pay attention Hygienic protection for young children, especially when the cold snap hits and the temperature drops, try not to let children suffer from respiratory infections.
