Mexanik jarohatda mahalliy va umumiy anesteziyadan keyingi yurakdagi morfologik o’zgarishlarining qiyosiy tavsifi

Abstract

Abstract. There are two main types of anesthesia: general and local. General anesthesia involves rendering a patient unconscious through the use of chemical agents, electrical stimulation, or psychological influence. Local anesthesia refers to the loss of pain sensitivity in a specific area of the peripheral nervous system due to the effect of drugs, physical, or mechanical factors [48]. Pain can also be blocked by compressing nerve fibers with agents like novocaine (novocaine, paracaine, chimyocaine, ethocaine). Novocaine is a colorless, odorless, tasteless crystalline substance that dissolves in water and alcohol. It is widely used for infiltration anesthesia in 0.25–0.5% solutions. Novocaine poisoning manifests with skin discoloration, dizziness, loss of consciousness, and vomiting. Pulse and respiration increase, blood pressure drops. The patient becomes restless, experiencing fear, anxiety, and hallucinations. In severe intoxication, unconsciousness, agitation, and convulsions may occur.
