Patient's question:
Often have nosebleeds, the baby also has dizziness or is very weakDoctor's answer:
Common Causes or Etiology of Nosebleeds: Nosebleeds are a common symptom of various clinical conditions. They can be caused solely by nasal lesions, accounting for about 1/2, or they can be a local manifestation of systemic diseases, also accounting for about 1/2. In children, nosebleeds most often occur in the anterior inferior part of the nasal septum, a region called the "Kiesselbach's plexus."Overall Factors or Etiology:
1. Acute Infections: If a child suffers from a cold, tonsillitis, pneumonia, or infectious diseases such as scarlet fever or mumps, high fever may develop. At this time, the blood vessels in the nasal mucosa may become intensely congested and swollen, even leading to capillary rupture and bleeding. Such nosebleeds are always accompanied by high fever.
2. Blood System Diseases: When suffering from blood disorders such as thrombocytopenic purpura, aplastic anemia, hemophilia, or leukemia, nosebleeds are often the earliest symptom. Children may experience inexplicable nosebleeds, and parents should pay special attention.
Local Factors or Etiology:
1. Trauma: Minor trauma, such as forcefully picking or blowing the nose, can damage the "Kiesselbach's plexus" of the nasal septum, leading to nosebleeds.
2. Inflammation: Local inflammation in the nasal cavity, such as acute or chronic rhinitis or sinusitis, can cause blood vessels to dilate or erode, resulting in nosebleeds.
3. Tumors: Tumors in the nasal cavity, sinuses, or nasopharynx are often rich in new blood vessels. If they develop ulcers, tissue necrosis, or secondary infections, they may manifest as nosebleeds.
4. Climate Factors: Dry climate can cause the nasal mucosa to dry and form crusts, leading to nosebleeds.
What to Do When Nosebleeds Occur?
1. First, parents should remain calm and comfort the child. Avoid appearing panicked in front of the child, as this may cause fear, crying, and anxiety, worsening the bleeding.
2. Use simple and effective methods to stop the bleeding quickly.
- Pressure Method: First, have the child sit slightly leaning forward. Ensure the child breathes through the mouth and pinches the nostrils tightly, closing both nostrils for 10 minutes. The pressure must be maintained continuously for at least 10 minutes. This is usually effective for mild nosebleeds.
- Packaging Method: Use a sterile cotton ball coated with Yunnan Baiyao to plug the nostril, or use a hemostatic sponge. In this case, observe the throat. If blood flows downward into the throat, it indicates that the nosebleed has not stopped.
- Finger Tying Method: Tie a rope tightly around the middle joint of the middle finger. For left-sided nosebleeds, tie the right hand; for right-sided nosebleeds, tie the left hand. If bleeding occurs on both sides, tie both hands simultaneously.
- Guiding Method: Soak both feet in warm water, or apply mashed garlic to the soles of the feet. For right-sided nosebleeds, apply to the left sole; for left-sided nosebleeds, apply to the right sole.
3. Pay attention to prevention in daily life. Children with a history of nosebleeds should actively exercise, drink more water during dry weather, and apply a small amount of oil to the nasal cavity to keep the mucosa moist. Avoid picking or forcefully blowing the nose.
4. If these measures do not stop the bleeding and the bleeding persists for more than 20 minutes, seek medical attention immediately.
5. If you suspect a nasal fracture, apply ice. If the head is struck and followed by nosebleeds, it may indicate a skull fracture, which is a medical emergency.
Regardless of the cause or etiology, even if the nosebleed stops, it is important to see a doctor to identify the underlying cause, eliminate the pathogenic factors, and prevent recurrence.
