Comparative StudyLong-tapered double needle used to reduce needle stick nerve injury.
Needle trauma may cause peripheral nerve injuries during performance of peripheral nerve block. ⋯ The long-tapered needles produced the least number of transected nerve fibers after sciatic nerve puncture.

Randomized Controlled Trial Clinical TrialTransdermal fentanyl in postoperative pain.
The aim of this study was to determine the safety and effectiveness of a transdermal fentanyl delivery system for the relief of pain following abdominal surgery. ⋯ Similar postoperative analgesia was achieved with less parenteral analgesics in patients who received transdermal fentanyl preoperatively than in control patients. Fentanyl, 50-75 micrograms/h, administered in a transdermal delivery system, did not depress respiratory rate or hemoglobin oxygen saturation. Although the exact role of continuously administered opioids in managing acute postoperative pain has yet to be clearly defined, it is concluded that if properly used, this new transdermal device can be effective in providing a background of analgesia, which may assist in the management of acute postoperative pain as well as some chronic pain states.

Comparative StudyRole of needle gauge and tip configuration in the production of lumbar puncture headache.
Postdural puncture headache (PDPH) is a morbidity that occurs frequently after lumbar puncture. The purpose of this study was to evaluate the role of needle diameter and tip configuration in causing PDPH. The incidence of PDPH was evaluated in parturients because this group of patients is at high risk for developing PDPH and because they often undergo lumbar puncture for spinal anesthesia. ⋯ The morbidity associated with lumbar puncture can be decreased by selecting the proper needle gauge and tip configuration. Use of the smallest gauge needle and one that has a noncutting Whitacre tip produces the lowest incidence of PDPH in parturients, a group of patients at increased risk for developing PDPH.
