Abortion said half anesthesia, is injected in the cervix several points of lidocaine for anesthesia, general anesthesia is through the intravenous injection of isoproterenol for anesthesia. Semi-anesthesia is the patient in a fully awake state, and will feel pain during the operation. General anesthesia is the patient is in a sleep state, the patient does not have pain during the operation to complete the operation, this is the difference between the two. In addition, half anesthesia surgery in the clinic is only to reduce the discomfort and pain when the dilatation, but in the suction of the uterus will still feel the pain, so if the pain-sensitive patients, it is recommended to do the general anesthesia surgery, that is, clinically referred to as painless abortion, very humane.
