Review Meta Analysis
Evaluation of Transversus Abdominis Plane (TAP) Block in Hernia Surgery: A Meta-analysis.
Transversus abdominis plane (TAP) block reduces opiate requirements and pain scores in abdominal surgery, but the effect has not been evaluated in hernia surgery. The aim of this study was to evaluate the efficacy of TAP block in hernia surgery. ⋯ Within a heterogeneous group of RCTs, TAP block reduces postoperative morphine requirements and the severity of pain after hernia surgery.

Randomized Controlled Trial
Effect of Epidural Dexmedetomidine Combined with Ropivacaine in Labor Analgesia: A Randomized Double-blinded Controlled Study.
The purpose of our study is to evaluate the effect of adding dexmedetomidine to epidural ropivacaine in patients undergoing labor epidural analgesia. ⋯ Low concentration of epidural ropivacaine (0.125%) combined with dexmedetomidine (0.5 μg/kg) reduces the feeling of pain, and does not show the problems of motor blockage, hemodynamic instability, extension of production process, and complications such as nausea and vomiting. Our study was registered with Chinese Clinical Trial Registry (ChiCTR-IOR-15007263).

Numerous neuroimaging techniques have been recently used to investigate central mechanisms involved in pain perception and to examine morphological and functional brain alterations associated with chronic pain. Compared to self-reporting approaches, objective imaging techniques are expected to potentially lead to better pain assessment and guide management. This comprehensive scoping review aims to identify recent magnetic resonance imaging (MRI) approaches that have been used to characterize the brain of chronic pain subjects, using structural, chemical and functional MRI techniques. ⋯ From our clinical experience, we have noted that most clinicians are not aware of the capabilities of advanced MRI methods in assessing cortical manifestations of chronic pain. In addition, many clinicians are not aware of the cortical alterations present in individuals with chronic pain. This comprehensive scoping review thus sets out to first summarize MRI neuroimaging techniques that are available in the current literature to examine chronic pain. We then identify cortical MR approaches that have been able to reliably predict transition from acute to chronic pain. Finally, we summarize MRI neuroimaging techniques that have been used to track treatment response of individuals with chronic pain.

To describe racial/ethnic group differences in pain presentation and the prevalence of psychosocial factors among patients admitted to home health care, and to determine the extent of racial/ethnic group differences in the association of psychosocial factors with pain intensity and pain-related disability. ⋯ The substantial racial/ethnic difference in the psychosocial profiles of older adults with activity-limiting pain highlights the importance of screening for these modifiable risk factors and tailoring interventions accordingly. Direct attention to the psychosocial needs of patients could help to address racial/ethnic disparities in pain outcomes.

Randomized Controlled Trial
Perioperative Transcutaneous Electrical Acupoint Stimulation for Postoperative Pain Relief Following Laparoscopic Surgery: A Randomized Controlled Trial.
This trial was conducted to assess the influence of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pain intensity and the optimal time of TEAS application during perioperative period in patients undergoing laparoscopic surgery. ⋯ Combination of preoperative TEAS with intraoperative or postoperative TEAS, rather than preoperative TEAS alone, is an effective and safe adjunctive for management of postoperative pain following laparoscopic surgery.
