The nasal cavity is the main channel of breathing for small babies, which can moisten and filter the inhaled air and maintain the health of the body. But the baby is not breathing well, you can not always think that he has a cold, we have compiled five causes of nasal congestion and prevention methods, hope that parents will help. A cold nasal congestion Because the baby’s thermoregulatory center is not very perfect, the nasal mucosa is tender and weak, the respiratory tract resistance is poor, easy to catch a cold. Subsequently, acute edema of the nasal mucosa occurs, causing nasal congestion. Performance: nasal congestion and runny nose, slightly red on both sides of the nose, some accompanied by fever. Prevention and treatment countermeasures: 1, about half a month after birth, the baby began to supplement the appropriate amount of cod liver oil; 6 months to add supplementary food, supplement vitamin A, can feed some liver puree, carrot puree, vegetable puree, enhance the respiratory defense ability; 2, the use of air conditioning, indoor and outdoor temperature should not be too big contrast, baby room to 28 ~ 30 degrees Celsius is appropriate; 3, with a warm wet towel on the baby’s nose for hot compresses (not too hot), twice a day. (not too hot), twice a day, each time about 15 minutes. Second, acute sinusitis nasal congestion baby repeatedly on the sense can involve the mucosa of the sinuses, making it congested and swollen, increased secretions, blocking the sinus mouth caused by acute sinusitis. Performance: In addition to nasal symptoms such as nasal congestion, runny nose, open mouth breathing, etc., the heavier there are fever, headache, sore throat, irritability and other symptoms. Prevention and treatment measures: 1, if the baby has upper sensation, should be actively treated; 2, once the acute sinusitis, promptly take the baby to see a doctor in the ENT department, under the guidance of a doctor reasonable choice of antimicrobial agents, in order to completely cure, to prevent recurrence; 3, baby nasal congestion is serious, can be used under the guidance of a doctor cautiously 0.5% ephedrine furacilin drops, 10 to 15 minutes before eating a drop of each side of the nostril, generally A few minutes to be able to work. However, ephedrine has side effects on small babies, not suitable for excessive or long-term use, so as not to cause atrophic rhinitis and affect the olfactory sensitivity of the nose; 4, when the baby has a lot of pus nasal discharge, you can ask the doctor to do replacement therapy to remove the purulent secretions from the sinuses. Third, the nasal mucosa will have a normal amount of secretions every day, because the baby can not blow his nose, the mother did not remove the baby’s nasal secretions in a timely manner, the secretions will accumulate in the nasal tract, over time, the accumulated secretions will dry and harden and form a nasal scab. Performance: The nasal crust adheres to the external or deep nasal cavity and blocks the narrow nasal passage. Countermeasures: 1. Remove nasal secretions for baby in time; 2. Avoid picking baby’s nose with hands when removing nasal crusts to avoid damaging the tender nasal mucosa and causing bleeding and infection. The correct method: If the nasal scab is blocked in the nostril opening, use a small sterilized cotton swab to gently roll it away. If the nasal dirt is deeper in the nasal cavity, you can first use saline, cold water or breast milk to put 1 to 2 drops into the nostrils to slowly moisten and soften the nasal scabs, then gently squeeze the nasal wings to gradually loosen the nasal scabs, and then use a small sterilized cotton swab to roll the nasal scabs away. Fourth, foreign body blockage Babies are curious, sometimes playing with some small stones, small blocks, small whistles, buttons, small rubber head, bottle caps, paper balls, love to stuff these small things into the nose; sometimes will eat sunflower seeds, peanut rice, fried beans, nuts while stuffing these things into the nasal cavity. Because the baby’s nasal cavity is small, these things stuffed in, they can not get out, can not tell Mom and Dad, and then forget, the foreign body will remain in the nasal cavity. Some babies suffer from nasal vestibule eczema, because of the itch, they use stuffed things to rub to relieve the itch. Performance: Most of the nasal cavity is blocked on one side, poor ventilation; if secondary infection occurs, the mucus gradually becomes purulent; if the foreign body stays too long, it can cause the nasal mucosa to erode, grow granules, bleeding nasal discharge and emit a foul smell. Preventive measures: 1. educate the baby to develop good habits of hygiene, not to stuff the nose, once stuffed to tell mom and dad, take out foreign bodies as soon as possible; 2. parents should pay attention to observe the baby’s breathing, once found that the baby has a side of the nose blockage phenomenon, or unexplained runny nose, odor, take the baby to the doctor in a timely manner. The actual allergic rhinitis nasal congestion Allergic rhinitis is divided into seasonal and perennial. Perennial allergic rhinitis can develop throughout the year, mostly caused by fungi, dust mites, insect secretions, animal fur and so on. Performance: nasal congestion is obvious, sneezing more, often runny. Prevention and treatment countermeasures: 1, avoid baby contact with dust, mites, fungi, animal fur, feathers and other allergens. For example, do not use down pillows, down quilts and Simmons mattresses; do not let babies close to cats, dogs, birds and other pets. In the season of pollen dispersal, do not take your baby to places where flowers and trees are abundant, and do not pick and smell flowers and plants; 2, often bring moisture and dust in the living room, open the windows to keep the air fresh; 3, do not give your baby spicy food, fried food and seafood, do not drink indiscriminately; eat more fresh fruits and vegetables, drink more plain water; 4, often take your baby to outdoor activities, develop the good habit of washing face and hands with cold water, to improve the body’s ability to adapt to and resist climate change. 5.
