Maintenance of anesthesia is the next stage of induction. At this stage, the patient has lost consciousness and the body is gradually stabilizing. However, at this stage, the patient can still be threatened by the effects of surgery and anesthesia, so this stage requires close monitoring to prevent, detect early and handle complications that may occur.
