Randomized Controlled Trial Comparative Study Clinical TrialAmethocaine-lidocaine cream, a new topical formulation for preventing venopuncture-induced pain in children.
The aim of this study was to compare the effectiveness of 3 anesthetic creams in relieving venous puncture-related pain in children. ⋯ All 3 creams proved to be effective in relieving venous puncture pain in children. EMLA presented a longer latency period, 4% amethocaine showed the highest percentage of untoward effects, and AMLI exhibited a shorter latency period than EMLA, while having fewer adverse effects than 4% AMET and EMLA.

Percutaneous electrode guidance: a noninvasive technique for prelocation of peripheral nerves to facilitate peripheral plexus or nerve block.
Typically, peripheral nerve block is done by approximating nerve location, usually by use of anatomical landmarks. Precise nerve location has been done by needle exploration. A new method, percutaneous electrode guidance (PEG) of the block needle, was performed. A transcutaneous stimulating cylindrical electrode was used to indent the skin, locate the underlying nerve, and guide a block needle near it. ⋯ A smooth, metal-tipped electrically shielded skin electrode probe can be used to comfortably and accurately indent the skin over a desired nerve or plexus, define its anatomical course, and subsequently guide a block needle near it.

Randomized Controlled Trial Comparative Study Clinical TrialPreemptive analgesia: no relevant advantage of preoperative compared with postoperative intravenous administration of morphine, ketamine, and clonidine in patients undergoing transperitoneal tumor nephrectomy.
Preemptive analgesia often failed in the clinical arena because application of a single intravenously applied drug may not prevent nociceptive input and spinal pain processing sufficiently. We therefore used an intravenous (IV), multireceptor approach and tested the preemptive analgesic effect of the antinociceptive drugs morphine, ketamine, and clonidine given before or immediately after surgery. ⋯ In contrast to encouraging observations on the combination of antinociceptive drugs, the multireceptor approach tested here failed to exert a clinically relevant effect.

Randomized Controlled Trial Clinical TrialAnalgesic effects of dexamethasone in burn injury.
Glucocorticoids are well-known adjuvant analgesics in certain chronic pain states. There is, however, a paucity of data on their analgesic efficacy in acute pain. Therefore, the aim of the study was to examine the analgesic effects of dexamethasone in a validated burn model of acute inflammatory pain in humans. ⋯ The study indicates that systemic administration of dexamethasone 2 hours before a burn injury does not reduce the inflammatory-mediated changes in quantitative sensory thresholds, pain perception, or skin erythema in humans.
