First aid for wounds

Fundamentals of First Aid (OPMP)

wounds called mechanical damage to tissues with a violation of the integrity of the cover. With deep wounds, not only the skin with subcutaneous tissue is damaged, but also muscles, bones, nerves, tendons, ligaments, and sometimes large blood vessels.

A wounding object can penetrate into the body cavity - the abdominal cavity, the cranial cavity, etc.; such penetrating wounds are often accompanied by damage to internal organs. When injured, bleeding, pain, and almost always gaping, i.e., divergence of the edges of the wound, necessarily occur. Wounds themselves are dangerous when bleeding from a large vessel, wounding an internal organ, especially severe pain that causes shock. In other cases, the main danger of injuries is that they serve as an entrance gate for pathogens of infectious complications, and sometimes such dangerous common infectious diseases as tetanus and rabies.

First aid for any injury - protecting the wound from secondary contamination. The surrounding skin is lubricated with an alcoholic solution of iodine and a sterile bandage is applied, strictly observing the rules of asepsis, especially avoiding touching the wound itself. In scalped wounds, the flap often does not come off completely and can be folded to the side with the subcutaneous tissue outward. In this case, the flap is carefully lifted and its skin surface is also smeared with an alcohol solution of iodine.

If the wound bleeds profusely, assistance begins with a temporary stop of bleeding. In severe wounds of the extremities, transport immobilization is necessary.

For further treatment, the wounded must be taken to a clinic or hospital to see a surgeon. The need for immediate surgical care increases with visible contamination of the wound with earth, with the possible presence of foreign bodies, poisonous or radioactive substances in the wound. The most urgent transport on a stretcher is for the wounded with symptoms of shock, severe bleeding and with such wounds that may be penetrating (for example, stab wounds of the chest, abdomen).

Persons bitten by a dog, cat or other animal should seek medical attention immediately, even if the wound is minor, to avoid contracting rabies.

Small, shallow wounds with a small area of damage, with little dehiscence of the edges and no visible contamination often heal by first intention under a bandage applied with proper first aid. But even with these wounds, an appeal to the surgeon is mandatory if, 1-2 days after the wound, pain resumes in the wound, which indicates the onset of an infectious complication. This applies primarily to cuts and pricks of the fingers, which threaten the development of panaritium.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Google patents augmented reality watch 09.10.2012

The popularization of "smart" watches began quite recently, and so far there are still quite a few players in this segment of the market. However, the American corporation Google also showed interest in this industry and received a patent for the use of augmented reality technology in watches.

The search giant filed a request for a patent about a year ago, and this week it was approved by the US Trademark and Patent Office (USTPO). The document states that Google's SmartWatch is equipped with a camera, a flip-down transparent cover-screen and a built-in Wi-Fi module for connecting to wireless networks. The device works as follows: when the user flips the transparent cover, it will turn into a screen that will display information about the object at which the camera built into the watch is directed. In addition, using the gadget, the user will also be able to view notifications and use Google services.

In general, the device described in the patent is much more advanced than the smart watches from Sony or Pebble already on the market, and therefore it is interesting how exactly Google is going to implement its idea. Currently, nothing is known about any prototypes or prototypes, and therefore if the company actually decides to turn its idea into a real product, then the appearance on the shelves of Google SmartWatch stores is unlikely to happen soon.
