Sulfone? Muscle? Local anesthesia is the application of anesthetic to temporarily block nerve conduction in a certain area of the body, resulting in anesthetic effect, referred to as local anesthesia. Local anesthesia is simple and easy, and the patient can stay awake with little physiological interference, so it is suitable for small and medium-sized operations with small body surface limitations. In a wide range of operations, local anesthesia is often not perfect for pain relief, muscle relaxation effect is not good, and local anesthesia surgery has a certain failure rate. Some patients have allergic reactions to local anesthetics and need general anesthesia. The success of local anesthesia depends on the anesthesiologist's mastery of surgical techniques, local anesthesia characteristics and local anatomy. In addition, for children, even minor surgery, because children are difficult to cooperate, it is best to take general anesthesia. General anesthesia is the use of narcotic drugs to suppress the central nervous system, feel no pain, relax muscles and temporarily lose memory. Tracheal intubation is often used in general anesthesia to isolate respiratory tract and digestive tract. Even if the patient vomits, it will not cause aspiration by mistake, which can ensure full satisfaction of lung ventilation, analgesia and muscle relaxation. If the patient has an accident during the operation, he can also be rescued in time. In this respect, general anesthesia has greater advantages than local anesthesia. At present, general anesthesia tends to use short-term, reliable and mild adverse reactions. After the operation, these drugs will be cleared by the body quickly, and most patients will wake up immediately. But sometimes because the patient's condition is complicated, it will be more dangerous if he wakes up immediately, and the anesthesiologist will consciously delay the patient's waking time. This is only a measure for the safety of patients, not a complication of anesthesia. General anesthesia itself will not damage the patient's brain. Of course, general anesthesia is characterized by the need for certain equipment, complicated operation and relatively high cost. The choice of anesthesia is mainly determined by three factors, namely, surgical factors, patient factors and anesthesia factors. Surgical factors include mode, size, time and location. Patient factors include the patient's condition, age, physiological function and economic conditions. Anesthesia factors include narcotic drugs, equipment, habits of anesthesiologists, etc. Before general surgery, the anesthesiologist will make a comprehensive understanding of the patient and make an anesthesia choice that is beneficial to the patient after integrating the above factors.
