(1) What is local anesthesia + sedation? Local anesthesia + sedation, in short, is an anesthetic method in which a dose of hypnotic-sedative and analgesic drugs are given intravenously by an anesthesiologist before and during a local anesthetic procedure to put the patient to sleep and reduce the discomfort of the procedure. Anesthesia is required for most surgical procedures, such as, local, regional and general anesthesia. Of these, local anesthesia is administered by surgeons for many familiar plastic surgery procedures, such as, blepharoplasty, rhinoplasty, eyebag removal, wrinkle removal, and breast augmentation. However, when it comes to having surgery, everyone feels nervous and anxious. The pain of injecting local anesthetics, the pulling during surgery, and even the environment of the operating room can add to the patient’s psychological burden. Therefore, for patients who are more nervous, we can use sedation to make the patient quiet and comfortable to receive and complete the local anesthesia surgery. (2) How is local anesthesia + sedation administered? After the patient enters the operating room, intravenous fluids are administered. A certain amount of hypnotic-sedative and analgesic drugs are given by the anesthesiologist through a three-way tube, which can make the patient quiet quickly, and some patients can enter a light sleep, effectively reducing the patient’s tension, alleviating the pain of the injection of local anesthetic and surgical operation, and making the surgical procedure more comfortable. (3) Is local anesthesia + sedation safe? It is relatively safe. Because there is an anesthesiologist present during the operation, ECG, respiration, blood oxygen, etc. will be continuously monitored, and the anesthesiologist will detect and handle all accidents in time. (4) Who can use local anesthesia + sedation? Local anesthesia + sedation can be used for most outpatient and ward local anesthesia procedures, especially for patients who are more nervous and fearful. In addition, the elderly, patients with coronary heart disease, diabetes and other chronic diseases should also use local anesthesia + sedation, which can reduce the impact of the malignant stimulus of “surgery” on the body, and appropriate monitoring can also increase the safety of surgery. However, adults and children with poor cooperation and control should not use local anesthesia + sedation, but should be selected for general anesthesia. (5) Precautions: Preoperative fasting should be 8 hours and 3 hours of water fasting. There is also a period of time after the surgery when food cannot be consumed. After outpatient surgery, you should stay for at least 2 hours and leave the hospital only after you are fully awake.
