Rhinosinusitis in children is a common disease in pediatrics, and if not diagnosed and treated promptly, some serious complications can occur. What should children with rhinosinusitis do? Regarding the treatment of rhinosinusitis in children, nasal irrigation is a safe and effective treatment method that should be the preferred option for treatment and can be widely used for various inflammatory diseases of the nasal cavity and sinuses in children. Nasal rinsing is the first choice for children with rhinosinusitis Nasal sinusitis in children is a common disease in pediatrics, and because children’s immune mechanisms are not well developed, they suffer from a high number of colds each year, of which 0.5% to 5.0% will develop into nasal sinus infections. The four main symptoms of rhinosinusitis in children are nasal congestion, runny nose, posterior nostril drip and cough, which can easily lead to otitis media, recurrent lower whistle infections and pediatric snoring. If the diagnosis and treatment are not timely, some serious complications can occur. In addition to medication, nasal irrigation is also an effective treatment to reduce inflammation and can be widely used for various inflammatory diseases of the nasal cavity and sinuses in children. Nasal irrigation can improve the function of mucus cilia removal, remove secretions, reduce mucosal edema, reduce inflammatory mediators, and can effectively play an anti-inflammatory and anti-allergic role, which can be applied to all stages of rhinosinusitis and significantly relieve the symptoms of nasal congestion, runny nose and post-nasal drip in patients with rhinosinusitis. It can also be applied to allergic rhinitis, post-nasal endoscopy, fungal rhinitis and other conditions. It is simple, inexpensive, easy to use and has few side effects. There are more methods of nasal irrigation, nasal spray and transnasal nebulization. The effectiveness of nasal irrigation, nasal spray and transnasal nebulization is compared, and it is found that nasal irrigation can distribute the rinse solution more widely in the nasal cavity and sinuses than the other two methods, so nasal irrigation is recommended as the method of nasal irrigation. However, nasal irrigation has a large flow of water and is prone to side effects such as choking, nasal bleeding, and ear pain, so it can be difficult to apply in children. For nasal cleansing, choose a professional nasal irrigator The use of nasal cleansing treatment requires the use of a special irrigator, preferably a nasal washer with the same frequency as the normal oscillation on the mucous membrane of the nasal cavity. In more serious cases, appropriate medication can be used for treatment. The pulsed nasal rinse can reduce the patient’s pain response and improve compliance. It adopts the principle of nebulized pulsation, which atomizes the rinsing solution into a soft water mist and rushes it into the nasal cavity in the form of pulses. This method of nasal rinsing atomizes the drug into small particles, with a wider diffusion range, and the rinsing solution is more likely to spread to the deep nasal cavity and the cleft, acting directly on the mucous membrane of the nasal cavity, with rapid onset of action and improved drug utilization. The use of saline to cleanse the nasal cavity is very common in the treatment of chronic rhinosinusitis and allergic rhinitis in children. When using a nasal washer to cleanse the nasal cavity, attention should be paid to the concentration of saline and the rinsing time, as too high or too low a concentration, or too frequent rinsing or too long rinsing time may affect the normal physiological function of the nasal mucosa. Whether it is necessary to wash the nose with saline and take professional and correct treatment measures. Nasal rinsing should become a habit of our life like brushing teeth, which is a cure for patients and a health care for normal people and should be adhered to for a long time.
