Randomized Controlled Trial
Continuous transversus abdominis plane (TAP) blocks for postoperative pain control after hernia surgery: a randomized, triple-masked, placebo-controlled study.
Single-injection transversus abdominis plane (TAP) block provides postoperative analgesia and decreases supplemental analgesic requirements. However, there is currently no evidence from randomized, controlled studies investigating the possible benefits of continuous TAP blocks. Therefore, the aim of this randomized, triple-masked, placebo-controlled study was to determine if benefits are afforded by adding a multiple-day, ambulatory, continuous ropivacaine TAP block to a single-injection block following hernia surgery. ⋯ The results of this study do not support adding an ambulatory, continuous ropivacaine infusion to a single-injection ropivacaine TAP block for hernia surgery. However, the present investigation was underpowered, and further study is warranted.

This analysis aimed to determine reliability, validity, and responsiveness of the pain on movement (POM) questionnaire, an instrument developed to determine pain intensity induced by head movement. ⋯ The POM seems to be a reliable and valid instrument to assess POM in patients with chronic nonspecific neck pain.

Chronic pain is associated with impairments in sleep; however, the relationship between prescription opioid status and sleep is unclear. The primary aim of this study was to examine differences in self-reported sleep quality between groups of patients who varied based on chronic pain and prescription opioid status. ⋯ Prescription opioid status and dose were associated with impairment in self-reported sleep. For patients with chronic pain, consideration should be given to use of nonpharmacological interventions to improve sleep.

Randomized Controlled Trial Multicenter Study
A randomized study of lubiprostone for opioid-induced constipation in patients with chronic noncancer pain.
To evaluate the efficacy and safety of oral lubiprostone for relieving symptoms of opioid-induced constipation (OIC) in patients with chronic noncancer pain. ⋯ Lubiprostone effectively relieved OIC and associated signs and symptoms and was well tolerated in patients with chronic noncancer pain (http://clinicaltrials.gov/ct2/show/NCT00595946).
