Bleeding is the bleeding of blood from blood vessels, which occurs as a result of any damage. Depending on the types of damage, types of bleeding are traumatic (due to injuries) and non-traumatic (corroding of vessels by painful foci, for example, with tuberculosis, oncology, ulcers).
The main symptom of a wound is traumatic bleeding. The liquid flows due to shock, injection, incision, which violates the walls of blood vessels.
Blood coagulation is individual for each person. Thanks to such a protective mechanism, the body protects itself from large blood loss and spontaneously stops any small, mainly capillary bleeding. The wound is clogged by the resulting clot. Also, bleeding can be stopped by squeezing the vessel.
Bleeding is called insufficient blood clotting. It can manifest itself in slowness or disproportionate duration. People who suffer from this ailment can bleed slowly with minor tissue damage.
Any kind of bleeding is a danger to the human body. A large loss of blood can cause not only dysfunctions of the body, but also a fatal outcome. First of all, the brain, heart and lungs will not be adequately supplied with oxygen. As a result, hypoxia of the brain may occur .
Depending on the place where the blood flows, the types of bleeding are usually divided into external and internal. With the latter, there is an accumulation of liquid connective tissue in the body cavities.
External bleeding, the types of which are represented by capillary (blood oozing drops from superficial wounds), venous (dark red fluid flows abundantly from a deep wound), arterial (bright scarlet blood flows from a deep wound) and mixed (from veins and arteries), removes blood from the human body.
Often in women after the birth of the baby, postpartum hemorrhage opens. Fetal membranes contribute to this, their remains that are in the uterus, low blood pressure, atonic state of the uterus, coagulation disorder, rupture of the uterine cavity.
After childbirth, the cavities of the membranes are examined in detail to determine their completeness. The most common cause of bleeding is the inability of the uterus to contract, that is, the presence of uterine postpartum atony. Even stimulation is unable to cause uterine contractions.
Dysfunction of the myometrial layer is caused by gestosis, cardiovascular diseases, kidney or liver diseases, a disorder of the central nervous system, scarring of the myometrium, uterine neoplasms, and uterine cavities. The aforementioned disorders are promoted, for example, by multiple pregnancy, a large fetus.
The types of postpartum hemorrhages are divided according to their symptoms. There are abundant, in which the uterus is in a state of atony, and undulating, in which the uterus periodically relaxes and releases blood clots.
Doctors are able to timely and correctly restore the tone of the uterus, stopping bleeding. If assistance is not provided, the body’s reserves, which compensate for large blood loss, run out, which leads to an increased blood flow. Often hemostasis is added to this and hemorrhagic shock occurs .
Therapeutic methods for postpartum hemorrhage are medical, mechanical and surgical. With a negative result for these methods, doctors do a manual analysis of the walls of the uterine cavity. In addition, manual massage is performed in order to stimulate the uterine contractility. With inefficiency, surgical methods are used.
