Parents are hesitant about adenoidectomy mainly because of the following misconceptions: 1. The damage of general anesthesia on intelligence. This is unfounded speculation. How many cases of general anesthesia are performed every day around the world? If general anesthesia could affect intelligence, how many mentally retarded children would there be on earth! The safety of general anesthesia is much greater than local anesthesia, because there is an anesthesiologist to monitor the child’s vital signs, and any abnormalities can be dealt with in a timely and correct manner. In the case of local anesthesia, the operator has to perform the surgery and monitor the child’s vital signs, so if there is any abnormality, there is not enough manpower for first aid, which may lead to extreme situations. With the escort of an anesthesiologist, the operator will feel much more at ease, and the efficacy of the surgery will be guaranteed. 2. Adenoids are immune organs and cannot be removed. I do not deny that adenoids are immune organs during childhood. However, it is not possible to completely remove the lymphatic tissue in the nasopharynx by adenoidectomy, but the excess lymphatic tissue that affects the nasal airway is removed. A thin layer of lymphatic tissue will be left in the superficial layer of the prevertebral fascia, and this preserved lymphatic tissue will also play its proper immune function. 3, surgery blood loss, affecting the physical condition of the child. Now the use of low temperature plasma technology has been able to achieve the entire procedure bleeding in less than 5ml. Eliminate the process of hemostasis, but also can greatly shorten the anesthesia time, reducing the risk. 4, post-operative pain, parents, especially grandparents can not bear to let their children suffer. Low-temperature plasma surgery after almost no pain feeling.
