The mechanisms underlying the pathogenesis of neuropathic pain are complex but are gradually coming to light. Agents that have been found effective in a variety of neuropathic pain conditions include drugs that act to modulate (a) sodium or calcium channels, (b) N-methyl-D-aspartate receptors, (c) norepinephrine or serotonin reuptake, (d) opioid receptors, and (e) other cellular processes. Clinical trials have primarily evaluated these treatments for postherpetic neuralgia and painful diabetic neuropathy, the two most common types of neuropathic pain. ⋯ Currently available diagnostic tools are inadequate to determine the best treatment using a mechanism-based model. Clinically, drug treatment of neuropathic pain is often a matter of treatment trials. This article presents a summary of available clinical information on first-line and lesser-known treatments for neuropathic pain.

Randomized Controlled Trial Clinical Trial
Analgesic effects of oral sucrose and pacifier during eye examinations for retinopathy of prematurity.
Oral sucrose reduces pain during heel sticks and venipunctures in preterm infants, but no studies have been done to determine the effectiveness of sucrose during eye examinations for retinopathy of prematurity. Therefore, the purpose of this study was to determine the effectiveness of local anesthetic eye drops and a pacifier, plus repeated doses of 24% sucrose, to relieve pain associated with eye examinations for retinopathy of prematurity. In this double-blind randomized controlled trial, 30 preterm infants were randomly assigned to one of two treatments, in which they received either local anesthetic eye drops, a pacifier, plus three doses of sterile water or local anesthetic eye drops, a pacifier, plus three doses of 24% sucrose during the eye examination. ⋯ The mean PIPP score was 8.8 for the sucrose group and 11.4 for the water group ( t = 2.87, p = .008 two-tailed). No significant differences were found in PIPP scores immediately following the procedure. Sucrose and a pacifier may be beneficial for minimizing pain during eye examinations in preterm infants and should be considered as a part of evidence-based guidelines for relieving pain during this procedure.

Patients with neuropathic pain present a clinical challenge. Neuropathic pain, when chronic, often leads to disability. Diagnosis can be difficult because both positive and negative sensory and motor signs and symptoms may be present, as well as a variety of comorbid conditions. ⋯ Patients may be confused by the unusual sensations they are experiencing and unable to effectively describe or communicate their symptoms. This communication barrier may contribute to an inadequate physical examination. With improved skills in patient assessment and through enhanced communication with patients, nurses can make an important contribution to treatment outcomes in patients with neuropathic pain.

Abstract Needle procedures are a necessary component of the treatment of hospitalized children. However, for many children they can be both painful and distressing. There was concern among the nurses at our pediatric hospital that we were not adequately controlling pain from needle procedures. ⋯ A topical anesthetic was used for 74 procedures (i.e., 19%), and the majority of these procedures were performed on the medical day unit with oncology patients. Results of the survey provided information about the day-to-day practice of needle procedures in order to identify both the supports and the barriers to providing these procedures atraumatically. Examining needle procedures within a framework of atraumatic care broadened our perspective and enabled us to integrate the use of topical anesthetics as just one of a number of strategies to minimize the pain and distress associated with needle procedures.
