If the operation of pediatric cryptorchidism is performed by conventional surgery, the anesthesia can be non-intubated general anesthesia and combined with sacral anesthesia. Non-intubated general anesthesia uses some general anesthetic drugs to put the child in a quiet, sleeping state, so that the child will not be in pain and will not move, and then perform the operation of sacral anesthesia. Sacral canal anesthesia is performed at the lower end of the spine and the sacral triangle at the upper end of the tailbone. Sacral puncture is an invasive operation, so the child should only be operated under basic anesthesia, otherwise it may cause damage to other parts of the body. Usually non-intubated general anesthesia with sacral canal anesthesia is good enough for most routine cryptorchid surgery.
