Clinical TrialEvaluation of epidural sensory block by thermal stimulation, laser stimulation, and recording of somatosensory evoked potentials.
The existence of differential sensory block during epidural analgesia has been confirmed by some authors and disputed by others. This study attempts to elucidate this issue by using quantitative methods for evaluation of sensory block. ⋯ No differential block of small nerve fibers was found during epidural analgesia by Thermotest and argon laser stimulation. Recording of somatosensory evoked potentials did not demonstrate significant difference between responses from the sites with most superficial and with most intense sensory block.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of meperidine and lidocaine for spinal anesthesia for postpartum tubal ligation.
This study compares the anesthetic potency, duration, and side effects of subarachnoid meperidine and lidocaine for postpartum tubal ligation. ⋯ Subarachnoid meperidine and lidocaine both provide adequate anesthesia for postpartum tubal ligation. Meperidine provided longer postoperative analgesia.

Randomized Controlled Trial Clinical TrialPreoperative spinal bupivacaine does not reduce postoperative morphine requirement in women undergoing total abdominal hysterectomy.
This study was undertaken to determine whether preoperative spinal anesthesia with local anesthetics would exert a pre-emptive effect on postoperative analgesia by reducing neural afferent stimulation. ⋯ The authors were unable to demonstrate that spinal block with bupivacaine before surgery, as opposed to after surgery, decreased the requirement of morphine in the postoperative period.

Warnings about the hazards of epidural steroid injections occasionally appear in both medical and lay literature despite a lack of objective data to support such concerns. This literature review was undertaken to survey reports of adverse reactions associated with that procedure. ⋯ There are few published reports of serious complications following epidural steroid injections. There are a few published reports of complications following subarachnoid steroid injections, most of which were associated with multiple injections over a prolonged time period.
