Syncope, fainting types

    So, fainting - it suddenly occurs
    transient loss of consciousness. Fainting is a mild form of acute
    cerebral vascular insufficiency. It is due to the lack of influx
    blood to the brain.

    Most mild fainting - swoon
    - Begins with a sudden a light misting of consciousness,
    dizziness, tinnitus, yawning. Patients fade, marked
    coldness of hands and feet, drops of sweat on his face. Actions:
    the patient should be immediately put on the back (in mild cases and can be
    just sit back with a support on the back of a chair, armchair). Note that
    nothing is placed under the head! The head should be at least
    flush with the housing. It is necessary to ensure good access of oxygen
    (One often leads to the cessation of fainting) - unbutton
    collar, if crowded around the fallen man a lot of onlookers -
    parted. It is necessary to reassure the patient that arises fear can
    provoke a spasm of cerebral arteries and increase brain ischemia. Can
    sprinkle on the face with cold water and bring to the nose cotton wool moistened
    alcohol. Usually attack swoon lasts a few seconds, but in any
    If you have time to put the patient and give him access
    oxygen, you can have peace of mind, consciousness, he does not lose.

    Syncope, fainting typesSimple swoon
    also typically begins with clouding of consciousness (ie, as
    swoon), and subsequently there is complete loss of consciousness
    off muscle tone, the patient settles slowly. arterial
    pressure is low, breathing is shallow, distinguishable only with difficulty. Attack
    It takes several tens of seconds (up to a maximum of 4-5 minutes), followed by
    rapid and complete recovery of consciousness. Actions:
    if the patient has lost consciousness, do not pull it or try
    lift. Consciousness will return when restored normal
    the blood supply to the brain, and the horizontal position is required for this
    body (vascular tone and sharply reduced if we raise our head or body,
    just ottechet blood in the lower limbs and of no normal
    blood supply, of course, we will not go). Do not try to find
    pulse, due to low pressure and loss of vascular tone, pulse
    wave is very weak, and you just do not find it. Medics
    is determined in such cases the pulse in the neck at the carotid artery (if you
    think you know, where is the carotid artery can
    try to find the pulse there). The rest, as well as with the swoon -
    the access of oxygen, ammonia. Do not seek to be poured on the patient
    polpuzyrka ammonia or wipe them whiskey - a solution of ammonia, and he
    It does not restore cerebral blood flow and stimulates the respiratory
    center through nerve endings in the nasopharynx (the person making the reflex
    breath and the body receives a large portion of the oxygen from the breath). Can,
    continuing to hold cotton wool with smelling salts at the nose for a few seconds to cover
    hand over her mouth - all the inhaled air goes through the nose and a pair of ammonia
    fall in the nasal cavity. You can, at worst, simply flip on
    the tip of the nose - a painful stimulus is also sometimes able
    stimulate the recovery of consciousness.

    convulsive syncope

    characterized by the addition to the picture fainting seizures (general,
    generalized or single twitches of individual muscle). Basically
    almost every brain hypoxia (lack of oxygen), continued
    20-30 sec., can cause similar symptoms.
    Actions do not differ from those with simple faint, but you must
    to ensure that during the mechanical seizure has not occurred
    head injuries, body, hands. Note: cramps can
    be characteristic of epileptic seizure (the typical
    signs are bite tongue, often screams or groans in
    early seizures (seizure vocalization), often appear redness
    and cyanosis of the face) and a hysterical fit.


    - It is fainting that occurs on a background of chronic lung disease. is he
    due to the fact that during prolonged bouts of coughing in the thoracic cavity
    significantly increased the pressure and venous blood flow from the cavity
    the skull becomes more difficult. However, in all these cases,
    We need to study the cardiovascular system to avoid
    Pathology of the heart. No specific actions are required.
    The duration of syncope often small.

    Drop attacks
    - It is unexpected, sudden fall sick. Thus practically
    He never lost consciousness, although there may be dizziness,
    severe weakness. It is usually seen in patients with cervical osteochondrosis
    spine complications vertebrobasilar-basilar
    insufficiency, and in otherwise healthy young pregnant women.

    vasodepressor swoon
    - More often in children often occurs when fatigue, sleep deprivation,
    emotional stress, stay in a stuffy room. It has
    rather complicated genesis of development. Actions do not differ from
    accepted, but requires careful examination to exclude
    possible diseases of the nervous system.

    Syncope, fainting typesorthostatic syncope
    - There is a sharp transition from horizontal to
    vertical when the cardiovascular system does not have time
    reconstructed to ensure full functionality of the brain. Special
    expressed while taking beta-blockers, diuretics, nitrates
    etc. More often, however, it is not faint, and so-called presinkopy,
    manifested in the sudden weakness, dizziness, blackouts
    with a change in body position.

    Carotid Sin Hypersensitivity Syndrome
    - Flows by type of simple or less, convulsive syncope. Driven by
    hyperactive carotid reflex (with the carotid sinus,
    located on the anterior side of the neck), which causes
    suddenly there is bradycardia, short-term heart failure,
    arrhythmia. Aggravating factors may be a sharp turn of the head,
    Wearing tight collars - hence the conclusion: never forget to
    helping to ease the collar to release the victim's neck.

    arrhythmic syncope
    - Unconsciousness and can cause certain types of arrhythmias. The main
    arrhythmias which can cause loss of consciousness, are
    paroxysmal atrial flutter and atrial fibrillation, complete
    transverse block, long QT syndrome, paroxysmal
    ventricular tachycardia. Other forms of arrhythmias rarely cause
    loss of consciousness, but each patient suffering from arrhythmia (and in
    especially the above arrhythmias), it is desirable
    consult your doctor about the possibility of him
    complications and, together with your doctor to develop a code of conduct that
    would allow to minimize the risk of such complications.
