MECHANICAL DAMAGE TO PREGNANT WOMEN
Injuries during different periods of pregnancy complicate the obstetric situation and can pose a direct threat to the life of the pregnant woman herself. According to the generally accepted classification, mechanical damage is distinguished by severity and localization.
Light injuries in the I and II trimester of pregnancy (up to 28 weeks), as a rule, do not affect its course, do not require obstetric and gynecological intervention, and the matter is often limited to traumatological care.
Light injuries in the III trimester of pregnancy (28-40 weeks) can provoke a threat of termination of pregnancy and premature birth. With severe injuries during pregnancy, bleeding from the genital tract due to miscarriage, the development of premature detachment of a normally located placenta, as well as another pregnancy pathology described above, may occur.
In these cases, the sequence and volume of trauma and obstetric care is determined by the leading, competing and concomitant diagnosis.
Severe mechanical injury (most often road traffic) can lead to antenatal death of the fetus and cause the atonal state, clinical and biological death of the pregnant woman.
With a gestational age of more than 37 weeks, a situation is likely when, with the established clinical death of the mother, the fetus remains viable for an indefinite time, which is established by listening to the heart tones of the fetus. In these cases, with the consent of the victim’s legal representatives, emergency operative delivery in the interests of the fetus is permissible.

MECHANICAL DAMAGE TO PREGNANT WOMEN
- MECHANICAL DAMAGE TO TISSUES
The consequences of mechanical effects on animals can be wounds, bruises, scratches, abrasions on the skin, bruises, lymphatic extravasation, stretching and tearing of tissues, ruptures of internal organs, abdominal hemorrhages, bone fractures, paralysis, paresis, and shell shock. In animals intended for slaughter, mechanical damages received on farms that occur upon delivery to places are detected
- Mechanical damage
Fractures One of the most common injuries in childhood is fractures, they, according to various sources, make up from 20 to 25% of all the lesions with which patients come to trauma centers. Nature provides for some mechanisms to protect the child from fractures: this is a developed, dense cover of soft tissues, which, like a pillow, weakens the force of impact when falling, and more
- Mechanical damage to the ear
From a hematoma. A hematoma is a hemorrhage between the cartilage and perichondrium of the auricle or, sometimes, between the perichondrium and the skin. The causes of a hematoma are injuries of the auricle in wrestlers, boxers, people with heavy physical labor, with prolonged pressure of a hard pillow or other item placed under the head, especially in people with impaired blood circulation, mainly in the elderly
- Hemolytic anemia associated with mechanical damage to the erythrocyte membrane
The causes of hemolytic anemia associated with mechanical damage to the erythrocyte membrane are presented in table. 42. Hemolytic anemia associated with mechanical damage to the erythrocyte membrane occurs in patients with prosthetic aortic valves due to intravascular destruction of red blood cells. Hemolysis is caused by the prosthesis device (mechanical valves) or its dysfunction
- Classification of mechanical damage (injury)
Depending on the depth of damage to the skin - whether the papillary (sprout) layer of the dermis is damaged or not, injuries can be closed (bruises, sprains, tears, dislocations, fractures, etc.) and open (wounds). Clinical and morphological classification of injuries: bruising (bruises), abrasions, wounds, concussions and ruptures of internal organs, dislocations, fractures, kneading and segregation (dismemberment).
- Causes of death due to mechanical damage
The causes of death due to mechanical damage are diverse, but the most common ones can be distinguished from them. Damage that is not compatible with life is associated with severe trauma to the body: amputation of the head, stretching of the head, separation of the body, extensive destruction of internal organs, etc. They occur when exposed to parts of a moving vehicle, falling from a height, gunshot injury.
- PLANTS CAUSING MECHANICAL DAMAGE TO TISSUES
Both the green parts of plants with sharp spines and spiky spines, as well as ripened fruits with sharp spikes, spikes and thorns, can cause injuries to animals. They damage the oral cavity, nasopharynx, gastrointestinal tract, as well as eyes, skin, inter-hoof spaces, udders and other organs. Damage to tissues is caused by feather grass, triosteum, bristle, moth, etc. However, more often
- Impotence in manufacturing bulls with mechanical damage, inflammatory processes and neoplasms in the genitals
Bruises of the foreskin and penis are usually the result of blows with blunt objects, excessive constriction of the foreskin with fixation straps, unsuccessful jumping of a bull on a mechanical scarecrow, or falls of an animal. Accompanied by a severe pain reaction, especially during erection and urination, inflammatory edema of the affected genital areas, general depression and inhibition of genital
- DAMAGE AND DAMAGE TO CELLS AND TISSUES. REASONS, MECHANISMS, TYPES OF IRREVERSIBLE DAMAGE. NECROSIS. APOPTOSIS
Under the influence of excessive physiological as well as pathological stimuli, the process of adaptation develops in the cells, as a result of which they reach a stable state that allows them to adapt to new conditions. If the limits of the adaptive response of the cell are exhausted, and adaptation is not possible, cell damage occurs. To a certain extent, cell damage is reversible. However, if

Terminology Dictionary Classification Closed injuries of the chest wall (First aid, Principles of treatment) Closed fracture of ribs Open injuries (injuries) of the chest and organs of the chest cavity Pneumothorax Hemothorax Nursing care for patients (First aid, First-aid
- Ligation of a damaged internal iliac vein and suturing of a damaged common iliac artery
Damage to the common iliac vessels can occur with laparoscopy during the introduction of the trocar and cannula or when the lymph nodes are removed for cancer. METHODOLOGY: Actions common for ligation and suturing 1 The right external iliac artery is most often damaged (as shown here), as most surgeons are better at administering and, accordingly, inject the trocar with the right
- Mechanical ventilation
1. When is mechanical ventilation indicated? Mechanical ventilation is indicated for: (1) animals that are unable to maintain Ra02> 50 mmHg. Art., despite breathing oxygen (through a mask, nasal catheters or in an oxygen tent); (2) animals unable to maintain PaCO2 <50 mm Hg. Art., despite the end of the action of respiratory depressants or thoracocentesis (if any
- Mechanical asphyxia
Hypoxia - oxygen starvation of organs and tissues, until the complete cessation of oxygen supply to the body. Asphyxia is the state of the body when, along with a lack of oxygen, carbon dioxide accumulates in it. Mechanical asphyxia arises from the action of an external mechanical factor. According to the pace of development, hypoxia is divided into: acute, developing and leading to
- Mechanical processing of materials
The specific emissions of harmful substances into the atmosphere from the main types of equipment for the mechanical processing of materials should be taken according to the methodology: “Methodology for calculating the emissions (emissions) of pollutants into the atmosphere during the mechanical processing of metals (based on specific indicators), Research Institute Atmosphere,“ Integral ”, C- St. Petersburg, 1997. This section shows the allocation of equipment,
- Mechanical methods
Mechanical condoms include a male condom, female caps, and diaphragms. Sometimes this method is called the barrier. Its essence is to create an obstacle for sperm to enter the uterine cavity and, therefore, to fertilize the egg cell. • Condoms The use of condoms (condoms) is an effective method of male contraception. Right them
- Mechanical methods
For many centuries, a variety of mechanical means have been used to prevent unwanted pregnancies. Male condom During the existence of the Roman Empire, condoms made from the lamb's cecum, goat's bladder, etc., were widely used. The prototype of the male condom was proposed by Fallopius in the XVI century. canvas bag
