Pre-emptive analgesia is defined as analgesic treatment initiated when?

• A. Analgesia after surgery
• B. Analgesic treatment initiated during the operation
• C. Analgesic treatment initiated after the start of surgery
• D. Analgesic treatment initiated before the start of surgery

Answer: (D)

The main idea is to block the nociceptive input before it begins so the nervous system doesn’t become sensitized to the upcoming pain. By giving analgesia before the incision is made, you blunt the initial pain signals and prevent central sensitization and wind-up in the spinal cord, which can reduce the intensity of postoperative pain and the need for additional analgesia. If analgesia is started after the incision or after the surgery has begun, the initial nociceptive input has already occurred, making it harder to prevent sensitization and control postoperative pain effectively. Therefore, the timing that defines pre-emptive analgesia is administration before the start of surgery.
