Randomized Controlled Trial Comparative Study Clinical TrialComparison of sufentanil, bupivacaine, and their combination for epidural analgesia in obstetrics.
We postulated that epidural sufentanil alone would provide adequate analgesia for labor and delivery. We also considered the possibility that a combination of epidural sufentanil and bupivacaine would demonstrate superior analgesia and fewer side effects when compared with either agent alone. ⋯ Epidural sufentanil alone does not reliably provide satisfactory analgesia for labor and delivery. Addition of small amounts of local anesthetic to bolus doses of sufentanil enhances and prolongs the analgesic effect.

Randomized Controlled Trial Clinical TrialEffect of epidural analgesia on colorectal anastomotic healing and colonic motility.
To examine the effect of epidural local anesthetic and narcotic agents on colonic anastomotic healing. ⋯ These findings suggest in this model that postoperative epidural analgesia is a safe technique after colorectal resection and anastomosis.

A dual-chambered syringe that allows identification of the epidural space using the loss of resistance technique with air and with saline.
Each of the two most widely used techniques for identification of the epidural space, the loss of resistance technique with air and the loss of resistance technique with liquid, has certain advantages and disadvantages. A new syringe is described that has two chambers, one to contain air and the other to contain liquid, to combine the advantages of air with the advantages of liquid, and to prevent the disadvantages of each. ⋯ The successful use of the EpIdent syringe in this preliminary study of 20 patients indicates that it provides a simple, safe, and effective means of identifying the epidural space. It allows the use of a plastic syringe (instead of glass) and avoids the unpleasant or untoward effects associated with currently used loss of resistance techniques.

Randomized Controlled Trial Clinical TrialAdding clonidine to mepivacaine prolongs the duration of anesthesia and analgesia after axillary brachial plexus block.
This study evaluates the effects of clonidine added to mepivacaine on the duration of anesthesia and analgesia after axillary brachial plexus block. ⋯ One hundred fifty micrograms clonidine added to mepivacaine for brachial plexus block prolongs the duration of anesthesia and analgesia. Our results suggest that this effect of clonidine is local rather than systemic.
