Intrathecal fentanyl in spinal anesthesia for appendectomy.

Objective: The authors assessed the effectiveness of the administration of fentanyl in spinal anesthesia for appendectomy.

Material And Method: Forty patients randomized double-blind, were recruited to receive either 4 ml of 0.5% hyperbaric bupivacaine + 20 mg of fentanyl (Group F) or 4 ml of 0.

Spinal morphine for post-operative analgesia after lumbar laminectomy with fusion.

Background: Intrathecal administration of preservative free morphine (spinal morphine) provides excellent post-operative analgesia. Since the dura is readily accessible by the surgeon during lumbar spinal surgery, it would be convenient and attractive to administer morphine into the spinal space to provide adequate post-operative analgesia in these patients.

Method: A prospective randomized controlled study evaluated the post-operative analgesic effect of spinal morphine after lumbar laminectomy with fusion.
