Intravenous lidocaine infusion has been shown to reduce postoperative pain among patients undergoing abdominal surgery. This study aimed to evaluate the effects of perioperative lidocaine administration in breast surgery. ⋯ The results indicate no significant benefits of intravenous lidocaine infusion in terms of acute postoperative pain. Although lidocaine seems to attenuate the risk of chronic pain after breast surgery, there is insufficient evidence to conclude that lidocaine infusion is of proved benefit because the results were based on a limited number of small trials.

Review Meta Analysis
Nervous System Sensitization as a Predictor of Outcome in the Treatment of Peripheral Musculoskeletal Conditions: A Systematic Review.
Research suggests that peripheral and central nervous system sensitization can contribute to the overall pain experience in peripheral musculoskeletal (MSK) conditions. It is unclear, however, whether sensitization of the nervous system results in poorer outcomes following the treatment. This systematic review investigated whether nervous system sensitization in peripheral MSK conditions predicts poorer clinical outcomes in response to a surgical or conservative intervention. ⋯ This systematic review found insufficient evidence to support an independent predictive relationship between QST measures of nervous system sensitization and treatment outcome. Self-report measures demonstrated better predictive ability. Further high-quality prognostic research is warranted.

Postoperative pain management protocols that use patient-controlled analgesia (PCA) can hinder mobility due to attached machinery and tubing. Immobility in the postoperative setting can increase complications, length of stay (LOS), and costs. Early and enhanced mobilization can reduce the cost of care while improving patient outcomes. A needle-free, compact, patient-activated, and portable fentanyl iontophoretic transdermal system (fentanyl ITS, IONSYS; The Medicines Company, Parsippany NJ) has been shown to provide comparable efficacy and tolerability to intravenous (IV) PCA morphine that promotes improved mobility. ⋯ Due to improved mobility with fentanyl ITS, complications are expected to be less frequent than with IV PCA and epidural PCA. Incorporation of this strategy into postoperative pain management protocols may reduce LOS and total hospital costs.

Review Meta Analysis
Inventory of Personal Factors Influencing Conditioned Pain Modulation in Healthy People: A Systematic Literature Review.
Conditioned pain modulation (CPM) is believed to play an important role in the development and exacerbation of chronic pain, because dysfunction of CPM is associated with a shift in balance between pain facilitation and pain inhibition. In many patients with central sensitization, CPM is less efficacious. Besides that, efficacy of CPM is highly variable in healthy people. Consequently, it seems that several individual variables may influence CPM. A systematic review examining personal factors influencing CPM was conducted. ⋯ It is advised for future studies to take these factors into account. Further research regarding the influence of oral contraceptives, catastrophizing, information about conditioning stimulation, distraction, physical activity, and genetics on CPM magnitude is required.

Review Meta Analysis
Disease-modifying Antirheumatic Drugs for the Treatment of Low Back Pain: A Systematic Review of the Literature.
Low back pain (LBP) is a common source of pain and disability, which has an enormous adverse impact on affected individuals and the community as a whole. The etiologies of LBP are protean and local inflammation contributes to the majority of these processes. Although an array of potent disease-modifying anti-rheumatic drugs (DMARDs), which are typically anti-inflammatory in character, have become clinically available only corticosteroids are routinely used for the treatment of LBP. ⋯ Moreover, the dose, frequency, and route of drug administration are selected arbitrarily and deviated from treatment protocols proposed for the management of other inflammatory conditions. The literature published on this topic is of low quality, and the results of the reviewed trials were inconclusive or demonstrated only short-term efficacy of these medications. Based on the findings of this review, we recommend that the future DMARD use for LBP is initially limited to patients with debilitating disease who are unresponsive to conventional treatments, and the criteria for drug selection and routes of drug administration are clearly defined and may be modeled after treatment protocols for other inflammatory conditions.
