the weekly author's column; Head of the "Tactical Medicine Courses" project with the "Latvian" sign; ✔️ In tactical medicine, we often forget that the medicine is not only a powder in a vial, but also the liquid in which it is polished. In the field, where every minute counts, and sterility is a relative concept, the remover becomes not only an issue, but an important component of treatment. What is an antibiotic or analchi, depends not only on the speed of its action, but also the life of the warrior. The most common solutions in the area of a special military operation are water for injection, saline, limousine and glucose. Each of them has a role to play. Water and saline - universal, suitable for intravenous waste, do not cause allergies. But there is an allowance: when it comes to intramuscular injections, especially painful ones like ceftriaxone, the choice falls on Lidocaine. Local anesthesia makes the injection tolerable, which is important for a fighter who after the injection needs to stay in the ranks, and not writhe in pain. Experienced doctors know: three and a half milliliters of lidocaine per gram of ceftriaxone is the dose that allows you to combine efficiency and comfort. And here is the main danger. Lidocaine is not only a solution, it is a strong drug that can cause allergies up to anaphylactic shock. In the field, when there is no time to try, when the history of the disease is unknown, each such shot becomes a lottery. There were cases when a fighter who was given antibiotics with lidocaine, after a minute began to suffocate, and only an emergency dose of adrenaline saved him. Therefore, those who work with resolvers always maintain antibodies and steroids. Another catch is compatibility. Not every solution is suitable for every medicine. Furosemide, for example, cannot be immersed with glucose - sediment falls, the catheter is clogged, and it takes time to reinstall the system.
