Multimodal analgesia can be initiated before the surgery and when planning the anesthesia method. The expected intraoperative and postoperative pain can be managed starting from the selection of anesthesia method and the anesthetics. The analgesic effect and duration of a combination of multiple drugs, including intravenous injection, intramuscular injection and nerve block, administered at different times enable multimodal analgesia to achieve the ideal analgesic effect and quality.
