Randomized Controlled Trial Clinical TrialAnalgesic effect of incisional morphine following inguinal herniotomy under spinal anesthesia.
Opioids have been shown to possess antinociceptive effects after peripheral administration in experimental and clinical studies. The results of clinical studies on intra-articularly administered morphine are, however, conflicting. The objective of this study was to examine a possible analgesic effect of incisionally administered morphine on postoperative pain in patients undergoing inguinal herniotomy. ⋯ A single 5-mg dose of morphine injected in the herniotomy wound did not affect pain scores or supplementary analgesic requirements, which argues against a role of peripheral opioid receptors in mediating analgesia.

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.

Comparative StudyAn in vitro comparison of fluid leakage after dural puncture with Atraucan, Sprotte, Whitacre, and Quincke needles.
The study was designed to evaluate the influence of needle size and design on the rate of leakage following dural puncture. ⋯ The comparably low leakage rate produced by the Atraucan, a new needle with a terminal opening, suggests that this needle is worthy of further clinical evaluation.
