Randomized Controlled Trial Comparative Study Clinical TrialThe peripheral analgesic effect of tramadol in reducing propofol injection pain: a comparison with lidocaine.
Tramadol and metoclopramide have a local anesthetic effect similar to lidocaine following intradermal injection. When metoclopramide was retained in the venous system for 1 minute, it was found to be as effective as lidocaine in reducing propofol injection pain. Using this metoclopramide model, the effects of tramadol in reducing pain on propofol injection was investigated. ⋯ Using -minute retention in veins, both tramadol and lidocaine significantly reduced propofol injection pain. A local anesthetic activity is postulated.

Comparative Study Clinical Trial Controlled Clinical TrialPercutaneous epidural neuroplasty: prospective evaluation of 0.9% NaCl versus 10% NaCl with or without hyaluronidase.
Percutaneous epidural neuroplasty (epidural neurolysis, lysis of epidural adhesions) is an interventional pain management technique that has emerged over approximately the last 10 years as part of a multidisciplinary approach to treating radiculopathy with low back pain. In addition to local anesthetic and corticosteroid, hypertonic saline (10% NaCl) and hyaluronidase are used for the technique. The objective of this study was to determine if hypertonic saline or hyaluronidase influenced treatment outcomes. ⋯ Percutaneous epidural neuroplasty, as part of an overall pain management strategy, reduces pain (sometimes for over one year) in 25% or more of subjects with radiculopathy plus low back pain refractory to conventional therapies. The use of hypertonic saline may reduce the number of patients that require additional treatments.

Randomized Controlled Trial Clinical TrialFrequency of hypotension during conventional or asymmetric hyperbaric spinal block.
The purpose of this randomized, double-blind study was to evaluate if use of an asymmetric spinal block affects the incidence of hypotension during spinal anesthesia. ⋯ Achieving an asymmetric distribution of spinal block by injecting a small dose of 0.5% hyperbaric bupivacaine through a Whitacre spinal needle into patients placed in the lateral position for 15 min reduces the incidence of hypotension during spinal anesthesia.
