What is nosebleed?
Nosebleeds are a common disease of the ENT organs, which is the leakage of blood from the vessels of the nose as a result of injury, local disease, or against the background of a disease in the body. It is considered an acute pathology and requires immediate emergency medical care. Lack of medical care leads to deterioration of a person's condition, even death. Therefore, underestimating this condition and considering it a short-term ailment is a common mistake of patients. There is a well-known fact in history when the leader of the Huns, Attila, did not capture the Roman Empire, dying in Western Europe from a nosebleed.
Diagnostic methods
To determine the exact reason why your head hurts and your nose bleeds, your doctor will prescribe additional tests. During the initial examination, you can determine the presence of foreign objects in the nasal passages, mechanical damage or inflammation of the nasal mucosa. Be sure to tell the doctor about all the medications the patient has taken recently, head impacts, and concomitant acute and chronic diseases.
To obtain a more accurate picture, additional tests may be prescribed:
- rhinoscopy - examination of the internal structures of the nose using an endoscope (the method allows you to identify polyps, tumors, foreign objects);
- Ultrasound of internal organs if pathology is suspected;
- clinical and biochemical blood tests - necessary for preliminary diagnosis of diseases of the hematopoietic system;
- MRI, CT scan of the brain for suspected traumatic brain injury.
At the Clinical Brain Institute, you can undergo a complete diagnosis for headaches and nosebleeds. Our center has precise and modern equipment, thanks to which the results of the examination will be known in a short time.
Causes of nosebleeds
To understand the causes of bleeding, you should know the anatomical structure of the nose and its functions. The nose and nasal cavity belong to the upper parts of the respiratory system. When we inhale, the air in the nose is cleaned, warmed and moistened. The vasomotor function is performed by the extensive vascular network located in it. When cold and dry air enters the nose, the vessels dilate and become full of blood, due to which the mucous membrane thickens and allows less air to pass through in order to warm and moisturize it. The opposite processes occur when warm, humidified air enters.
The vessels in the nasal cavity originate from the system of the external and internal carotid arteries. They are responsible for the blood supply to the anterior sections of the nasal septum. The weak point of the nasal vascular system is the anastomosis - the junction of capillaries from the external and internal carotid artery systems. There are two such places in the nasal cavity, and both of them are located in the area of the nasal septum. In the anterior sections it is the vascular bundle of Kisselbach (LocusKisselbahi), in the posterior sections it is the Woodruff bundle (plexusWoodruff). The vessels in the anastomotic area have a thin wall, covered on top with a thin mucous membrane of the nasal cavity. Therefore, minor injuries, increased pressure, dry cold air cause damage to these vessels.
A common cause of nosebleeds is injury. Such bleeding is called post-traumatic. But, in addition to traumatic ones, there are also iatrogenic causes. They represent nosebleeds after operations, manipulations in the nasal cavity (puncture, catheterization), installation of nasogastric or nasotracheal tubes during anesthesia or gastric lavage, endoscopic examination of the nasal cavity.
A deviated nasal septum, adenoid vegetations, aneurysms of the vessels of the nasal cavity, an oncological process or neoplasms in the nose are all risk factors.
Diseases of internal organs and diseases of the cardiovascular system can also cause nosebleeds. Most often it occurs in patients with hypertension with increased blood pressure. In case of incorrectly selected therapy and the patient does not comply with the doctor’s recommendations to stabilize the pressure, surges occur that lead to damage to blood vessels.
Cases of nosebleeds are common in patients taking anticoagulants (drugs that reduce blood clotting).
Ruptures of mucosal capillaries can also occur when:
- colds;
- taking narcotic drugs;
- frequent use of vasoconstrictor drugs;
- being in a dry and cold climate;
- overheating of the body (sunstroke);
- with vitamin deficiencies (vitamin C deficiency);
- with alcohol abuse;
- quickly diving into water or climbing a mountain.
Bleeding from the nose: causes
The nose is abundantly supplied with blood vessels with thin walls - capillaries. Therefore, even a minor injury can lead to bleeding, including heavy bleeding. In most cases (70%) the cause is mechanical damage. For example, a child may insert a foreign object into his nose, or an adult may blow his nose too much.
The provoking factor is too dry air, especially in winter. Therefore, in most cases, bleeding, although unpleasant, does not pose a threat to health and life. Along with mechanical damage, there are other reasons for this phenomenon:
- inflammatory processes;
- the occurrence of a tumor (polyps, papillomas, cancer);
- infectious diseases;
- increased body temperature (for example, due to infection or heat stroke, sunstroke);
- a sharp increase in blood pressure;
- use of non-steroidal anti-inflammatory drugs;
- excessive consumption of alcoholic beverages;
- pathologies of the heart and blood vessels.
Symptoms and classification of nosebleeds
Signs of a nosebleed are blood draining from the nostrils to the outside or down the back of the throat through the nasopharynx. Bleeding may be posterior or anterior. Anterior bleeding affects the Kisselbach capillary plexus, and posterior bleeding comes from large vessels and poses a great danger to the patient.
The main danger to life is the amount of blood lost. Normally, a healthy person has about 4-5 liters of blood in the body. With short-term bleeding, the volume of blood loss is up to 100 ml. This amount of blood loss does not greatly affect health, but depending on the type of nervous system, it can manifest as emotional excitement or fainting against the background of vegetative-vascular dystonia.
But if the volume of blood loss is more than 400-500 ml, then the patient develops weakness, dizziness, tinnitus, stars flashing before the eyes, the person becomes pale, the pulse quickens, and the blood pressure rises compensatory.
If the blood continues to flow and the volume of blood lost is up to 2-3 liters, then the patient shows signs of hemorrhagic shock. It becomes difficult to establish contact with the patient, shortness of breath increases, the skin turns pale, the extremities become cold, the hands, feet, and lips turn blue. Blood pressure decreases, the pulse is practically not palpable. The patient may lose consciousness.
Symptoms
The main symptom of epistaxis is blood coming out of the nostrils or entering the oral cavity from the upper part of the pharynx. In more severe cases, accompanying symptoms are revealed:
- weakness, nausea, disturbance of spatial orientation;
- feeling of fullness in the ears;
- headache;
- tachycardia;
- hypotension;
- pallor of the skin.
If blood ends up in the stomach, vomiting with blood clots occurs, and the stool becomes dark in color.
First aid for nosebleeds
- Call an ambulance or see an ENT doctor at the nearest clinic.
- Place the patient in a sitting position. Throwing your head back or lying down is undesirable. It is better to take a vertical position, placing a tray under your chin to determine the volume of lost blood.
- If the patient suffers from hypertension, measure blood pressure and take blood pressure-lowering medications prescribed by the doctor.
- Apply cold to the nose area and apply a cold towel to the collar area.
- Moisten cotton wool with 3% hydrogen peroxide and place it in the vestibule of the nose.
- Press the wing of the nose against the septum for 10-15 minutes.
First aid measures
When it comes to minor blood loss, you can get by with first aid at home.
The most important thing is to never follow the popular advice that says you need to throw your head back. When tilted, you will be able to open the airways into which secretions can enter. This will only worsen the overall clinical picture. Instead, you need to place the person on the bed, slightly raising the head end of the bed, and turn the head to the side.
If there was no concussion and losses are minimal, then it is enough:
- provide a flow of fresh air;
- apply cold to the bridge of the nose.
If the incident occurred in winter, you can use snow by putting it in a bag and placing it on the bridge of your nose. You can keep the cold compress for no more than ten minutes. Blowing your nose is prohibited, as is swallowing blood. When the characteristic taste persists, the accumulation of saliva, mucus with bloody clots is spat out.
You should act in exactly the same way if the catalyst for deterioration in well-being is heat, mild shock, or ARVI. When blood is released after a weightlifter's training, the powerlifter must adhere to the standard above algorithm.
But if the flow is observed for more than half an hour, then it is necessary to use more radical measures - roll up a swab of sterile cotton wool, moisten it in 3% hydrogen peroxide.
If a three-year-old child has a runny nose, it is recommended not to soak the turunda in peroxide, but to lubricate it with Vaseline. This measure is aimed at softening the dry mucous membranes that one has to deal with during illness.
In case of sunstroke on the beach, the person is transferred to a cool place by placing a wet cold cloth on the face. Ice is applied to the bridge of the nose so that the hot skin cools down quickly.
You also need to act if the problem arose when, against the background of crying, quitting smoking.
But if you feel dizzy, have purulent discharge, the bleeding does not stop, pink blood is constantly gushing out, and you feel tired, then you should not delay visiting the doctor.
Methods to stop nosebleeds
An ancient but effective method is anterior nasal tamponade. For tamponade, the doctor uses gauze turunda soaked in drugs. Using a nasal speculum and tweezers, the doctor establishes layers in the nasal cavity layer by layer from the vestibule of the nose to the nasopharynx and from the bottom to the upper sections. This method is effective, but has negative sides. Installing the turunda takes from 2-3 minutes to 10-15 minutes. The procedure is quite painful and difficult for patients to tolerate. Therefore, Merocell hemostatic tampons are used for anterior tamponade. These tampons are thin, so they are installed in the nasal cavity with minimal discomfort. After installation, the tampons are moistened with saline, under the influence of which they swell and fill the nasal cavity.
For posterior nosebleeds, when the source of bleeding is in the posterior sections of the nasal cavity and large vessels bleed, installation of a posterior tampon is indicated. The peculiarity of this method is that a special conductor is inserted through the nose, which is removed through the mouth. A tampon moistened with a hemostatic agent is tied to the end of the guidewire. The guidewire is pulled out of the nose and the tampon is inserted behind the soft palate into the nasopharynx, and then into the nasal cavity. The negative side of the method is the discomfort for the patient and the technical difficulty of performing it in an emotionally excited state.
An effective method of combating posterior and anterior nosebleeds, regardless of location, is the Epistop catheter. The catheter is a tube consisting of a system of three balloons. After installing the catheter in the nose, using warm water, the posterior balloon is inflated and compresses the vessels of the posterior localization. Then the middle-localized balloon is inflated, pinching the vessels in the area of the nasal turbinates and the middle nasal septum. And at the end, the anterior balloon expands, compressing the vessels in the area of the Kisselbach locus. The advantages of this method are that installation of such a catheter takes 1-3 minutes and the procedure is less painful for the patient.
Surgical methods to stop nosebleeds
In specialized institutions and clinics, if stopping posterior nasal bleeding using packing is ineffective, they resort to angiography (x-ray examination of blood vessels) and vascular embolization (cessation of blood flow through the vessel) of the nasal cavity under the control of an electron-optical converter. The listed methods are used in cases where the doctor is unable to identify the location of the bleeding. The reason for this is often bleeding from the deep parts of the nasal cavity.
In anterior nosebleeds, the source of bleeding is localized in the Kisselbach Locus region. And if the doctor has identified bleeding vessels, then the tactics to stop the bleeding are noticeably different from the listed methods.
Electrocoagulation
In almost all cases, in ENT practice, electrocoagulation is used to stop bleeding from the Kisselbach Locus. After preliminary local anesthesia, the bleeding vessels are cauterized with an electrocoagulator or Surgitron device. In our clinic, a similar procedure is performed under endoscope control. This allows for a good detailed examination of the nasal cavity, identifying damaged vessels and cauterizing them, minimizing the risk of relapse. But electrocoagulation has contraindications. An absolute contraindication would be an artificial ri driver. Electrocoagulation in this case can disable the pacemaker and lead to undesirable consequences for the patient, including cardiac arrest.
There are alternative methods to stop nosebleeds. Such as cauterizing bleeding vessels with preparations containing silver, or destroying vessels in the area of the Kisselbach locus using a sharp spoon called “abrasio”.
Often the cause of bleeding is a deviated nasal septum. By forming sharp protrusions, the deviated septum damages the nasal mucosa, thereby stimulating constant bleeding. In this case, the patient is indicated for surgical intervention. From local removal of a deviated section of the nasal septum (cristotomy) to complete correction of the nasal septum (septoplasty).
Prevention measures
Humidify the air in the room using a steam generator; you can also place wet towels on the radiator or spray the room with a spray bottle. Indoor plants also help humidify the air.

First aid: How to stop heavy bleeding from an open wound?
If crusts often form in your nose, periodically place 2-3 drops of sea buckthorn oil or rosehip oil into your nose.
For frequent bleeding caused by increased fragility of blood vessels, ascorbic acid and rutin are indicated.
Herbal teas from nettle, yarrow, knotweed, plantain, leaves and fruits of sea buckthorn, as well as a 5-10% solution of calcium chloride help increase blood clotting. It is taken 1-2 teaspoons 2-3 times a day after meals. This drug reduces the permeability of the vascular wall.
Bleeding caused by poor blood clotting may be associated with a lack of vitamin K. Its sources include spinach, lettuce, all types of cabbage, avocados, bananas, wheat bran, soybeans, meat, eggs, milk and dairy products, and olive oil.
Rehabilitation period after surgery
Stopping nosebleeds is a kind of surgical intervention, which requires daily observation by an ENT doctor and postoperative rehabilitation. Patients who have had nasal tampons or hemostatic sponges installed receive hemostatic therapy after stopping the bleeding. If necessary, they are transfused with components of lost blood and undergo therapy aimed at lowering blood pressure. On average, a patient stays with a tampon in his nose for 3-7 days. After which the tampons are carefully removed, and the patient is under daily medical supervision for several days. During the rehabilitation period, it is important to continue taking medications that strengthen blood vessels, accelerate healing and moisturize the nasal mucosa.
Is it possible to avoid frequent nosebleeds?
There are external and internal factors that provoke nosebleeds. Therefore, to prevent this, you should avoid these factors or take measures to treat the triggering diseases.
External factors:
- frequent use of vasoconstrictor drugs,
- dry, cold or polluted air.
Internal factors:
- arterial hypertension,
- deviated nasal septum,
- neoplasms of the nasal cavity.
