The Importance of the Saphenous Nerve Block for Analgesia Following Major Ankle Surgery: A Randomized, Controlled, Double-Blind Study.
Major ankle surgery causes intense postoperative pain, and whereas the importance of a sciatic nerve block is well established, the clinical significance of a supplemental saphenous nerve block has never been determined in a prospective, randomized, double-blind, placebo-controlled trial. We hypothesized that a saphenous nerve block reduces the proportion of patients experiencing significant clinical pain after major ankle surgery. ⋯ This study has been registered at ClinicalTrials.gov, identifier NCT02697955.

Symptoms of central sensitization (CS) have been described in patients with chronic spinal pain (CSP). Although a gold standard to diagnose CS is lacking, psychophysical pain measures are often used. The Central Sensitization Inventory (CSI) is proposed as an alternative method and indirect tool for the evaluation of CS symptomatology. The aim of the current study was to evaluate the convergent validity of the CSI by investigating the association with psychophysical pain measures and self-reported measures of current pain intensity, quality of life, disability, and catastrophizing in CSP patients. ⋯ The CSI was weakly associated with PPTs and not with CPM efficacy in CSP patients. Moderate to strong associations were found with current pain intensity, quality of life, disability, and catastrophizing. The current results illustrate that the CSI does not reflect a direct measure of CS, yet is a representation of general distress, possible originating from CS symptoms.

Comparative Study
Patient controlled analgesia: The impact of an 8 versus 10 minute lockout interval in postoperative patients.
The purpose of this study was to compare the level of pain control achieved with 8 versus 10 minute lockout intervals in adult patients who received patient controlled analgesia (PCA) within 24 hours of surgery. There was no difference in pain in the first 72 hours between the 8 minute and 10 minutes group. Additionally, there was no difference in time to first PCA regimen change or a composite outcome of adverse events.

Pain is one of the most common reasons for an individual to consult their primary care physician, with most chronic pain being treated in the primary care setting. However, many primary care physicians/non-pain medicine specialists lack enough awareness, education and skills to manage pain patients appropriately, and there is currently no clear, common consensus/formal definition of "pain chronification". ⋯ Early intervention plays an important role in preventing pain chronification and, as key influencers in the management of patients with acute pain, it is critical that primary care physicians are equipped with the necessary awareness, education and skills to manage pain patients appropriately.

Neuropathic pain is a frequent consequence of cancer pain. Quite often, in the end stage, it is difficult to discern its presence and delineate its characteristics in the context of painful cancer complications. The aim of this study was to compare the diagnostic accuracy of the Douleur Neuropathique en 4 Questions (DN4) and painDETECT questionnaires, which were translated to the patient's native language, for the diagnosis of peripheral neuropathic pain in oncology patients. ⋯ At standard cutoff values, the DN4 and painDETECT questionnaires, despite having been translated to the patient's native language, failed to adequately discriminate between neuropathic and non-neuropathic pain in our end-stage cancer patients.
