If the air-conditioned room is too dry, be careful of the child's nosebleeds, and the pediatrician will teach you how to prevent it.
Pediatricians found that there are many patients with nosebleeds recently. It is speculated that in addition to allergies and related diseases, it is also possible that the child stays in the air-conditioned room for too long and the humidity is too low, which leads to nosebleeds.
Hot weather or dry air can easily rupture the microvessels in the nasal cavity, leading to bleeding. For example, if the humidity in an air-conditioned room is low, staying too long or picking your nose with your hands may cause nosebleeds. Pediatrician Ou Shujuan reminded that it is best to put a glass of water around in the air-conditioned room. At the same time, a thin layer of vaseline is coated on the nasal mucosa with a cotton swab every day, which can isolate and protect the nasal mucosa, reduce sensitivity and prevent nosebleeds. But pay attention to the white part of the front end of the cotton swab, as long as it enters the nasal cavity, and don't poke it too deep.
Ou Shujuan said that the common causes of nosebleeds in children, including nasal allergies and curved nasal septum, will lead to fragile nasal mucosa. It may be that sneezing hard leads to microvascular rupture, and blood is sprayed through the nose; Children with nasal allergies often have itchy noses, rubbing their noses or picking their nostrils, causing nasal mucosal damage and bleeding.
In addition to the above, Chen Murong, director of grapefruit pediatric clinic, said on Facebook that many diseases can lead to nosebleeds, including chronic sinusitis, foreign body stuffing, nasal tumor, nasal polyps, perforation of nasal septum, trauma, vascular abnormalities, hemophilia, platelet dysfunction, thrombocytopenia, hypertension, leukemia, liver disease and so on. , can lead to nosebleeds, so parents should pay special attention.
Ou Shujuan added that in order to distinguish normal nosebleeds from nosebleeds caused by serious diseases, we can measure them by the frequency of attacks and the time to stop bleeding. Generally, pressing for 5 to 10 minutes can stop bleeding. If they can't stop bleeding after pressing for 30 minutes, it may be that there is something wrong with blood coagulation function, so they should be examined by a doctor. In addition, if you have more than/kloc-0 attacks in 1 week, or even have a nosebleed every day, be sure to see a doctor.
Ou Shujuan reminded that nosebleeds have three steps: squatting, pressing and ice compress. Never look up. "Bow your head" to confirm whether the nosebleed has stopped; "Pressing" means pressing the hard bones and cartilage of the nose, which is probably a little lower than the nose pad of glasses. After pressing for 5 minutes, you can let go of the observation. Ice compress is suitable for eyes between nose root and eyebrows. This is the upstream of the nasal blood vessels. When it is cold, blood vessels will contract, which can cut off the blood source and reduce the amount of bleeding. The ice time should not exceed 5 minutes, and it can be circulated for 2 to 3 times, with a rest every 5 minutes 1 minute.
The doctor reminded that nosebleeds must not look up, so as to avoid blood flowing back into the throat, which may make you sick if swallowed, or cause aspiration pneumonia; The blood clot that has stopped bleeding should wait for it to fall off itself to avoid bleeding again.
To prevent nosebleeds, we can start with diet. Ou Shujuan pointed out that in addition to oral drugs and nasal sprays, allergies should be controlled by eating less processed foods in the diet to reduce the probability and severity of allergies. Include artificial colors, high-temperature frying, food additives, preservatives and the like. , should try to touch less.
Zhang Jiabei, a Chinese doctor, also said that children with nosebleeds have a combination of lung heat and stomach heat. If nasal allergy belongs to lung heat, it is necessary to control allergic symptoms at ordinary times, eat more tremella, or strengthen the control and maintenance of the condition through dog stickers; As for stomach fever, we should eat less hot foods, such as ice cream, durian, hot pot, barbecue, fried and other high-calorie and oily foods. In addition, sweets, mung bean soup, barley and other heat-clearing desserts are best not to touch, so as to avoid phlegm in sweetness and make allergies more difficult to control.
