Abstract
Anesthesiologists are required to maintain the patient’s cooperation along with adequate sedation, analgesia, and anxiolysis throughout the whole procedure. It is reported that the administration of anesthesia using dexmedetomidine at the operation of awakeness is effective. We made anesthesia using dexmedetomidine and fentanyl on the operation of the right upper extremity. We were capable of observing the wake-up test without letting the patient feel pain or stress.
