Review Meta Analysis
Effects of Single Nucleotide Polymorphisms on Surgical and Post-surgical Opioid Requirements - A Systematic Review and Meta-analysis.
There is great heterogeneity in the way individuals respond to medications. Inherited differences, such as single nucleotide polymorphisms (SNP), can influence the efficacy and toxicity of drugs. This meta-analysis aims to collate data from studies investigating the effect of SNPs on postoperative and/or intraoperative opioid requirements. ⋯ Investigation of single changes in 1 gene can only yield limited information regarding genetic effects on opioid requirements. Rapid development of whole genome sequencing enables information on all genetic modifications that may affect analgesic response to be collected. The information collected must include data on the individual's metabolic enzymes, as well as information on drug receptors and enzymes responsible for drug degradation, so that a personal profile can be built up which will predict individual response to drugs, and guide clinicians on the type and dosage of drug to use.

Meta Analysis
Benefit and harm of pregabalin in acute pain treatment: a systematic review with meta-analyses and trial sequential analyses.
Pregabalin has demonstrated anti-hyperalgesic properties and was introduced into acute pain treatment in 2001. Our aim was to evaluate the beneficial and harmful effects of pregabalin in postoperative pain management. We included randomized clinical trials investigating perioperative pregabalin treatment in adult surgical patients. ⋯ Based on trials with low risk of bias, pregabalin may have a minimal opioid-sparing effect, but the risk of SAEs seems increased. However, the GRADE-rated evaluations showed only moderate to very low quality of evidence. Consequently, a routine use of pregabalin for postoperative pain treatment cannot be recommended.

Review Meta Analysis
Low-Dose Naloxone for Prophylaxis of Postoperative Nausea and Vomiting: A Systematic Review and Meta-analysis.
To determine whether postoperative administration of low-dose intravenous naloxone decreases the incidence of postoperative nausea and vomiting (PONV) and its impact on postoperative opioid requirements and pain scores. ⋯ This pooled analysis of data suggests that low-dose naloxone plays no role in preventing PONV, while exhibiting no significant effects on postoperative opioid needs and pain scores. The reduction demonstrated in postoperative nausea did not translate into decreases in postoperative vomiting.

Review Meta Analysis
Perioperative pregabalin administration does not prevent chronic postoperative pain. Systematic review with a meta-analysis of randomized trials.
The efficacy of perioperative pregabalin treatment for preventing chronic pain remains a matter of debate. We searched the MEDLINE, EMBASE, LILACS, Cochrane, and Clinical Trial Register databases, and other sources, for randomized controlled trials comparing the effects of pregabalin and placebo. The primary outcome was the incidence of chronic postsurgical pain (CPSP) at 3 months. ⋯ Subgroup analysis by publication status, daily dose, type of administration, and type of surgery did not highlight any differences between subgroups. Insufficient data concerning the incidence of chronic postsurgical neuropathic pain were available for any firm recommendation to be made. Pooled data from published and unpublished studies provide no support for the efficacy of pregabalin for preventing CPSP.

Review Meta Analysis
Risk factors for postoperative delirium following hip fracture repair in elderly patients: a systematic review and meta-analysis.
No formal systematic review or meta-analysis was performed up to now to summarize the risk factors of delirium after hip surgery. ⋯ Related prophylaxis strategies should be implemented in elderly patients involved with above-mentioned risk factors to prevent delirium after hip surgery.
