[Intrathecal opiate-spinal anesthesia. Clinical results of a 1-year study using 0.0375-0.15 mg morphine].
In a prospective study, 184 patients were studied after orthopedic operations with regard to analgesic requirements, analgesic effectiveness, and appearance of postoperative complications. In four groups, 0.0375, 0.075, 0.1 or 0.15 mg morphine was given in combination with 0.5% hyperbaric bupivacaine for perioperative analgesia. The patients' ages ranged between 13 and 90 years (means = 62.97). ⋯ The application of small doses of opiate close to the spinal cord produced a good and long-lasting reduction of pain with few opiate side effects. In the spinal anesthetics with larger doses of morphine, side effects were rare and hardly different from those accompanying spinal anesthesia without morphine addition. There were no serious complications noted during the opiate anesthesia.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports[Subarachnoid placement of a peridural catheter with high spinal anesthesia. The advantage of 0.25 % bupivacaine].
A 72-year-old female patient was scheduled for abdominal surgery with epidural block in combination with general anesthesia. An 18 G epidural catheter was inserted through an 18 G Tuohy needle between T12 and L1 using the midline approach and the 'loss of resistance' technique. A test dose of 13 ml bupivacaine 0.25% showed no effect and a bolus of 12 ml bupivacaine 0.25% was added 8 min later. ⋯ A spinal X-ray with radiopaque dye showed a typical intrathecal distribution. Most remarkable in this case is the stability of the cardiovascular function which in our opinion is related to the 0.25% solution. Serious complications of an inadvertent dural puncture can be avoided or alleviated with this concentration if the epidural block is to be combined with general anesthesia.
