The controversy over preemptive analgesia continues unabated, with studies both supporting and refuting its efficacy. The timing of an analgesic intervention and presence of a placebo control may have significant impact on the interpretation of results and may have led to the premature conclusion that preemptive analgesia is of limited clinical utility. A review of the recent literature using strict definitions of preemptive and preventive analgesia is required in order to clarify the broader issue of the benefits of perioperative analgesia. ⋯ Studies that used a preventive design had a greater likelihood of finding a beneficial effect. The application of preventive perioperative analgesia (not necessarily preincisional) is associated with a significant reduction in pain beyond the clinical duration of action of the analgesic agent, in particular for the N-methyl-D-aspartate antagonists. The classical definition of preemptive analgesia should be abandoned in favor of preventive analgesia. This will broaden the scope of inquiry from a narrow focus on preincisional versus postincisional interventions to one that aims to minimize postoperative pain and analgesic requirements by reducing peripheral and central sensitization arising from noxious preoperative, intraoperative and postoperative inputs.

Clinical outcome data was analyzed for 67 patients with contained disc herniation who underwent percutaneous disc decompression procedure using Coblation(R) technology, also referred to as Nucleoplasty after failing to respond to conservative management. Patients presented with clinical symptoms of discogenic low back pain and/or leg pain and were not considered candidates for open surgery. Follow-up data was collected up to 12 months. ⋯ Average pre-procedure pain level for all patients was reported as 6.8 while average pain level was 4.1 at the 12 month follow-up period. Statistically significant improvement was observed in 62%, 59%, and 60% of patients in sitting, standing, and walking ability at 12 months, respectively. The results of this analysis indicated that PDD using Coblation technology, also referred to as Nucleoplasty, is an effective procedure for patients presenting with discogenic back and/or leg pain who have failed conservative therapies and are not considered candidates for open surgical interventions.

Most peripheral neuropathies involve large as well as small-fiber dysfunction. A small subset of neuropathies present with restricted or predominant small-fiber involvement. ⋯ Small-fiber neuropathies are a heterogeneous group of disorders. They vary in etiologies and require special attention, as many disorders are rare and the differential diagnosis is broad. Evaluation is often extensive and may need pathologic specimen. Many patients respond to symptomatic therapy, but some are difficult to treat.

Randomized Controlled Trial Clinical Trial
Watch needle, watch TV: Audiovisual distraction in preschool immunization.
To evaluate the effectiveness of audiovisual distraction compared with a blank TV screen in the reduction of pain associated with intramuscular immunization. ⋯ Watching cartoons did not distract children during needle injection nor reduce their pain. Looking at the TV screen was related to lower behavioral pain scores in the total sample.
