Awareness is an uncommon phenomenon during surgery. We report on a case of awareness experienced during spinal surgery. A 59-year-old woman was scheduled for anterior lumbar interbody fusion (ALIF) followed by posterior pedicle screw fixation for lumbar degenerative kyphosis. First, the patient underwent the ALIF procedure. The operative and postoperative course was uneventful. Two days after this operation, the patient underwent posterior pedicle screw fixation from L2 to S1. She was anesthetized with target-controlled propofol and a remifentanyl infusion. Intraoperatively, the target plasma propofol concentration was maintained at 2.4 ㎍/mL and remifentanyl was infused at between 2.0 and 4.0 ng/mL. On the day after the second operation the patient complained of awareness during the surgery. She had felt moderate pain during the incision of her back and muscle dissection and heard the noise of an electrosurgical cautery being used. Her description of intraoperative events coincided with our surgical procedure. Although the patient had traumatic memories of the surgical procedure, she was satisfied with the operative result. Fortunately, she has not suffered sleep disturbances or any other psychological symptoms.
