To do cosmetic surgery, although it is impossible to choose which anesthesia method to use in many cases, it is not fully understood. Experts said that the choice of general anesthesia (general anesthesia) or local anesthesia (local anesthesia) for plastic surgery usually depends on the characteristics of the operation and the patient's condition, in addition to spinal anesthesia and basic anesthesia. Choosing anesthesia First of all, safety experts pointed out that plastic surgery needs anesthesia in many cases to be successfully completed. However, many patients did not think too much about anesthesia before cosmetic surgery, nor did they question the anesthesia method. Most doctors do not emphasize the anesthesia method of cosmetic surgery too much, and anesthesiologists did not participate in the consultation. Patients can only see the anesthesiologist when they sign an anesthesia agreement or even lie on the operating table. But experts believe that patients should also need to master some knowledge of beauty anesthesia. The anesthesiologist pointed out that the operation mode of cosmetic surgery should be chosen by the surgeon, but the anesthesia mode should be chosen by the anesthesiologist, and the patient's wishes should be properly considered. In general, when choosing anesthesia methods in plastic surgery, the first thing is to ensure safety, the second is to meet the requirements of operation scope, the third is to choose anesthetics with fast metabolism degradation and easy control of anesthesia depth, and the last is to consider the principle of simplicity and complexity. According to experts, generally speaking, surgery with relatively simple operation and short duration usually adopts local anesthesia and is completed by the surgeon himself; When major surgery requires spinal anesthesia or general anesthesia, there will generally be a special anesthesiologist. There is no need to change color when listening to general anesthesia. Experts pointed out that because of the development of anesthesia, the proportion of general anesthesia in surgery is getting higher and higher. Some experts pointed out that many people have misunderstandings about general anesthesia, for example, they think that the risk of general anesthesia is far greater than other anesthesia, and general anesthesia will affect intelligence. He believes that the choice of anesthesia mainly depends on the location, nature, operation time and the patient's physical condition. General anesthesia has the widest application range, which is suitable for all major, medium and minor operations, while other anesthesia methods are only suitable for some operations, but it is not practical to carry out general anesthesia for all operations. In addition, all anesthesia methods have certain risks, and the probability of local anesthesia is not lower than that of general anesthesia. In some cases, general anesthesia is safer. It is also unreasonable to think that general anesthesia will affect intelligence, because it has been used for more than 60 years, and there is no scientific basis to prove that general anesthesia will affect intelligence. Moreover, narcotic substances will undergo a metabolic process, and with the passage of time, general anesthetic substances will be completely excreted through various channels, without causing residues in the body. Double eyelid surgery: Local anesthesia can meet the requirements. Nasal plastic surgery: it can be performed under local anesthesia or general anesthesia, mainly depending on the size of the surgical scope. Grinding cheekbones: Local anesthesia is generally used, and other methods can be selected according to the patient's condition. Grinding mandibular angle: generally, local anesthesia or "small milk" sedation anesthesia is used. Liposuction: local anesthesia, general anesthesia or nerve block anesthesia can be selected.
