fentanyl has been researched along with Allodynia in 110 studies
Fentanyl: A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)
fentanyl : A monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of N-phenyl-1-(2-phenylethyl)piperidin-4-amine with propanoic acid.

The 300-g filament was used 24 hours after the operation to induce a stimulus and delineate the extent of hyperalgesia from the periumbilical region. The stimulus was started outside the periumbilical region, where no pain sensation was reported, and continued every 0.5 cm until the 4 points of the periumbilical scar were reached (top, right side, left side, and bottom). The first point where the patient complained of pain was marked. If no pain sensation was reported, the stimulus was terminated 0.5 cm from the incision. The distance of each point from the surgical incision was measured, and the sum of the distances of the points was determined. (NCT01301079)

The pain threshold was assessed using six von Frey monofilaments (0,05 g; 0,2 g; 2 g; 4 g; 10 g e 300 g) in the periumbilical region in the postoperative period (24h after the procedure). The use of different von Frey monofilaments, starting with the lightest and ending with the heaviest, was separated by at least 30 seconds to reduce any anticipated responses due to a new stimulation that was performed too soon after the preceding stimulation. Three assessments were made for each monofilament, and this was considered positive when the patient responded to two of the determinations for each monofilament. (NCT01301079)

A slightly modified version of a previously described model of secondary hyperalgesia was used. Two copper wires contained in a microdialysis catheter were inserted in parallel over a length of 5 mm into the dermis of the right volar forearm. The wires were connected to a constant current stimulator controlled by a pulse generator to deliver rectangular and monophasic pulses with a duration of 0.5 mg at 2 Hz. Over a period of 15 min, the current was increased by targeting a pain rating of 5 on an 11-point numeric rating scale (0 = no pain and 10 = maximum tolerable pain) until the hyperalgesic area surrounding the stimulation site was fully established. Once the area was established, the current was held constant. Percent change from baseline in size (area) of secondary hyperalgesia after cessation of remifentanil infusion was calculated per group.
