Randomized Controlled Trial
[Prospective study on anesthesia for lumbar spine surgery--the effectiveness of the perioperative epidural anesthesia with buprenorphine].
We prospectively evaluated the efficacy of perioperative epidural buprenorphine for lumbar spinal surgery under general anesthesia. Twenty-eight patients were allocated into two groups; in one group (buprenorphine group), patients underwent the surgery under general anesthesia with perioperative epidural buprenorphine 0.2 mg, in the other group (control group), patients underwent the surgery under general anesthesia only. The epidural injection was within 2 levels of the cephalad segment of the operating site. ⋯ In buprenorphine group, requirement of analgesics was less during and after surgery compared with the control group. Neurological evaluation immediately after surgery revealed no neurological side effects in both groups. We conclude that general anesthesia with perioperative epidural buprenorphine for lumbar spinal surgery is safe and useful.

Surgery during pregnancy is suspected to have various harmful influences to pregnant patients and fetuses. Although laparoscopic surgery has been recently reported to have some advantages over open surgery in this condition, it often requires general anesthesia. ⋯ General anesthesia during pregnancy is not necessarily associated with harmful influences on mother and babies compared with lumbar and epidural anesthesia if selected appropriately.

Since no pre-medication has been widely accepted especially in spinal anesthesia, anesthesiologists should manage the control of patient's anxiety during surgery. Instead of sedatives, we have been using music-therapy during spinal anesthesia. Bispectral index monitoring (BIS) is used as one of the sedation indices in spinal anesthesia. The aim of this study was to assess the music-therapy on reducing anxiety of patients under spinal anesthesia using BIS and interview type psychology test, State Trait Anxiety Inventory (STAI). ⋯ Music-therapy reduced BIS value and was effective to reduce patient's anxiety during spinal anesthesia.
