RESUMEN
Interventional pain procedures offer treatments for chronic pain conditions refractory to conservative measures. Neuromodulation, including peripheral nerve stimulation (PNS), applies electrical stimuli to neural structures to treat pain. Here we review the literature on PNS for various chronic pain conditions including neuropathic pain, postamputation pain, musculoskeletal pain, migraine, and pelvic pain.

PURPOSE OF REVIEW: The objective of this systematic review is to present the available evidence for the utilization of the atypical opioids tapentadol, buprenorphine, and levorphanol for the treatment of neuropathic pain. RECENT FINDINGS: In total, 1619 articles were retrieved of which 10 studies were included. Of 5 included studies pertaining to tapentadol, 4 studies show tapentadol monotherapy to be effective for the treatment of diabetic peripheral neuropathy or chronic, radiating low back pain. Of the 3 studies included for buprenorphine, only one was a randomized controlled trial found not to have a statistically significant reduction in pain with TD buprenorphine likely due to very high withdrawal rates during the trial. Only 2 case reports were included from the available literature for levorphanol providing low-quality anecdotal evidence. The role of tapentadol, buprenorphine, and levorphanol for neuropathic pain conditions requires robust research including randomized controlled trials to evaluate their efficacy and safety.

OBJECTIVE: The aim of this study was to evaluate a nonsedating agent, lavender aromatherapy, to reduce anxiety before interventional spinal procedures. DESIGN: In this prospective, single-blind study performed at a tertiary care center for an academic institution, 144 patients undergoing spinal procedures (epidural steroid injection, medial branch block, or radiofrequency ablation) were randomized into two groups of 72 patients. The experimental group was exposed to a tablet formulation of lavender aromatherapy, while the control group was exposed to tablets devoid of any scent. The exposure duration for each group was 5 mins. The primary outcome measurement was patients' anxiety state before the spinal procedure using the six-item State-Trait Anxiety Inventory. Secondary outcomes quantified the rate of vasovagal events and aborted procedures because of patient intolerance. RESULTS: Compared with the control group, the posttreatment anxiety score of those exposed to lavender aromatherapy revealed a statistically significant difference as measured by the six-item State-Trait Anxiety Inventory (12.15 ± 2.67 and 10.67 ± 2.81, P < 0.05). Within group, the experimental group's anxiety level decreased from 12.26 ± 2.75 to 10.67 ± 2.81 (P < 0.05). There were two vasovagal episodes and one aborted procedure in the control group, whereas there was one vasovagal episode and no aborted procedures in the aromatherapy group. CONCLUSIONS: Lavender-based aromatherapy is effective in reducing preprocedural anxiety before interventional spine procedures for pain management.
