General anesthesia is needed for sieve sinusitis surgery, which may have certain risks, including during anesthesia, surgery and after surgery. 1. During anesthesia: Because general anesthesia requires more drugs, there may be allergic reactions, cardiovascular and cerebrovascular accidents, etc. For people without hypertension, coronary heart disease and other underlying diseases, the incidence of these risks will be slightly reduced. 2. During surgery: sieve sinus surgery is close to the cranium and orbits, so excessive operation may cause intranasal hemorrhage, cerebrospinal fluid nasal leakage, visual impairment, etc. 3. After surgery: when the intubation tube is removed after awakening, some patients cannot maintain normal respiration, which may cause laryngeal edema, etc. Some patients also have increased airway responsiveness after surgery, which may lead to the risk of respiratory distress. If surgery for sieve sinusitis is needed, it is recommended to be evaluated by a professional doctor before proceeding with the treatment to reduce the risk of surgery.
