Review Meta Analysis
Serious complications associated with external intrathecal catheters used in cancer pain patients: a systematic review and meta-analysis.
Potential risks of intrathecal catheters in cancer patients include infection, bleeding, and neurologic injury. ⋯ Serious complications are rare in both hospitalized and homebound patients with intrathecal catheters. This analysis supports the reasoning that the potential benefit of intrathecal catheters in the treatment of severe cancer pain is likely to outweigh the potential for serious complications associated with this technique. Therefore, an external intrathecal catheter can be considered an effective and low-cost solution for the control of pain in such patients.

Meta Analysis
Analysis of individual patient data from clinical trials: epidural morphine for postoperative pain.
Individual patient information from clinical trials is infrequently available, but can provide insights for clinical trials and practice. ⋯ Analysis of individual patient data from high-quality clinical trials provides important insights into characteristics of new agents not immediately apparent from original trials, and also informing clinical practice. Prophylactic epidural morphine provides a better patient experience than IVPCA alone.

Review Meta Analysis
Meta-analysis of the relevance of the OPRM1 118A>G genetic variant for pain treatment.
Regard of functional pharmacogenetic polymorphisms may further the success of pain therapy by adopting individualized approaches. The mu-opioid receptor gene (OPRM1) 118A>G polymorphism is a promising candidate for both opioid effects and pain because of both biological reasonability and apparent experimental and clinical evidence. We analyzed its importance for pain therapy using a meta-analytic approach to studies relating it to opioid pain therapy. ⋯ Only weak evidence of an association with less nausea (effect size, Cohen's d=-0.21, p=0.037) and of increased opioid dosage requirements (d=0.56, p=0.018) in homozygous carriers of the G allele was obtained. This indicates that despite initially promising results, available evidence of the clinical relevance of the OPRM1 118A>G polymorphism does not withhold a meta-analysis. This discourages basing personalized therapeutic concepts of pain therapy on OPRM1 118A>G genotyping at the present state of evidence.

Review Meta Analysis Comparative Study[Systematic review to assess the effectiveness and safety of parecoxib].
Conduct a meta-analysis of randomized clinical trials to assess the effectiveness and safety of parecoxib as analgesic for orthopedic surgery. ⋯ Parecoxib 40 mg is an effective and safe analgesic choice during the postoperative period in orthopedic surgery.

Review Meta Analysis
Efficacy and safety of different techniques of paravertebral block for analgesia after thoracotomy: a systematic review and metaregression.
Various techniques and drug regimes for thoracic paravertebral block (PVB) have been evaluated for post-thoracotomy analgesia, but there is no consensus on which technique or drug regime is best. We have systematically reviewed the efficacy and safety of different techniques for PVB. Our primary aim was to determine whether local anaesthetic (LA) dose influences the quality of analgesia from PVB. ⋯ Continuous infusions of LA predicted lower pain scores compared with intermittent boluses (P=0.04 at 8 h, P=0.003 at 24 h, and P<0.001 at 48 h). The use of adjuvant clonidine or fentanyl, pre-emptive PVB, and the addition of patient-controlled opioids to PVB did not improve analgesia. Further well-designed trials of different PVB dosage and drug regimes are needed.
