Which infusion technique is often used to maintain anesthesia during surgery?

The continuous infusion technique is commonly utilized to maintain anesthesia during surgical procedures due to its ability to provide a steady and consistent level of anesthetic agents in the patient's bloodstream. This method allows for a controlled delivery of drugs, ensuring that the patient remains at an appropriate level of anesthesia throughout the surgery.

By using a continuous infusion, anesthetists can adjust the rate of infusion based on the patient's response and needs, which enhances the safety and effectiveness of the anesthesia. It also helps in minimizing fluctuations in drug concentration, thereby reducing the risk of awareness during surgery or potential adverse effects from peaks and troughs in drug levels.

Other techniques, such as intermittent bolus or single-dose methods, might not provide the same level of control over anesthetic depth during prolonged surgeries, leading to potential challenges in maintaining appropriate anesthesia levels. Pulsatile infusion is less commonly utilized in this context as it does not typically support the steady state of anesthesia required during surgery.
