After water sports, if the child has abnormal cough, shortness of breath or even vomiting, it may be a manifestation of dry drowning. American "Parents" magazine pointed out that when dry drowning occurs, children look fine when they leave the swimming pool, but they may suddenly attack after several hours or even 24 hours. Mark, an emergency attending physician at Philadelphia Children's Hospital? Mark Zonfrillo explained that "dry drowning" and "secondary drowning" are both drowning injuries. In "dry drowning", the child inhales a little water from the nasal cavity, which causes the airway to spasm and contract. When drowning for the second time, water enters the lungs, causing inflammation or swelling, which makes it difficult to exchange oxygen and carbon dioxide in the body. Dry drowning usually occurs shortly after leaving water, but the second drowning may occur after 24 hours. Both of them can lead to dyspnea and even death in severe cases. To prevent dry drowning or secondary drowning, the most important thing is to pay close attention to whether the child has difficulty breathing within 24 hours after playing with water.
