Final answer:
Morphine is the opioid often used as an infusion for significant intraoperative stimulation and post-operative pain management, due to its potency and ability to be precisely dosed.
Step-by-step explanation:
The opioid commonly used as an infusion for significant intraoperative stimulation and post-operative pain is morphine.
Morphine is a potent opioid analgesic derived from the opium poppy and is widely used in medicine to alleviate severe pain.
It acts by binding to opioid receptors in the brain, spinal cord, and gastrointestinal tract, altering the perception of pain.
Morphine is available in injectable forms, which are typically used during and after surgical procedures to maintain pain control.
With its ability to provide pain relief over extended periods, morphine is suitable for situations where constant pain management is necessary.
The use of morphine as an infusion allows for precise control over the dosing, making it an effective option for managing varying levels of pain throughout the perioperative period.
Injectable anesthetics, such as morphine, are preferred for their quick onset and reliability compared to other administration routes.
