Anesthesia for adenoid surgery has some short-term effects on children, but in the long term there are virtually no effects. There are some short-term side effects of anesthesia, such as nausea and vomiting, and allergies. Nausea and vomiting can be prevented by preoperative fasting and water fasting. If vomiting still occurs, intraoperative suction and intra- or postoperative application of antiemetic medications (e.g., ondansetron) are effective in preventing complications such as aspiration of vomitus. For allergies, medications for anesthesia allergies (e.g., epinephrine) are available in the operating room and can be quickly administered by the anesthesiologist to control the condition. Although there are some risks associated with anesthesia for adenoid surgery, it is generally beneficial to the patient.
