Why does nose suddenly bleed?

There are abundant blood vessels and arteries on the mucosa on both sides of the nasal septum, so once injured, there will be a lot of bleeding. In addition, children's nasal mucosa is delicate, and blood vessels are superficial compared with adults and nasal cavity, which is more likely to cause bleeding. Let's talk about what is easy to cause children to have nosebleeds.

First of all, parents should calm down and comfort their children, and don't panic in front of them, which will make them afraid, cry and aggravate bleeding. Take some simple measures to stop nosebleeds as soon as possible. (1) Shiatsu method, let the child sit down first and lean forward slightly. Be sure to let the child breathe through his mouth, pinch his nose, close his nostrils for 10 minute, and keep squeezing for 10 minute. Generally, it can stop mild epistaxis.

② Packing method: Stick Yunnan Baiyao with sterile cotton balls, stuff it into nostrils, or stuff it with hemostatic sponge. At this time, we should pay attention to the pharynx. If there is blood flowing down the throat, it means that the nosebleed has not stopped. (3) Finger pricking: Tie the middle part of the middle finger tightly with a rope, prick a left nosebleed with the right hand, prick a right nosebleed with the left hand, and prick two nosebleeds with both hands at the same time. ④ Instruction: Soak your feet in warm water, or mash garlic and apply it to the soles of your feet. The right nosebleed is attached to the heart of the left foot and the left nosebleed is attached to the heart of the right foot.

If this treatment can't stop the nosebleed and the bleeding lasts for more than 20 minutes, you must see a doctor. If you think there may be a broken nose, you can use ice. If other parts of the head are hit, and then nosebleeds, it may prompt skull fracture that the situation is urgent. No matter what the reason is, even if the nosebleed is stopped, you should see a doctor to find out the cause of nosebleed, remove the pathogenic factors and prevent it from happening again.

Environmental factors. When the child is in a relatively dry air environment, such as cold and dry season, it is easy to cause the child's nasal mucosa to be dry, fragile and prone to bleeding.

Cold allergy. When a child catches a cold, his immunity will decrease, and the resistance of nasal mucosa will also decrease. In addition, some cold symptoms, such as nasal congestion, runny nose, and nasal allergies, will lead to children's behaviors such as wiping their noses and picking their nostrils, which will easily lead to nosebleeds.
