RESUMO
PURPOSE OF REVIEW: In the USA, there has been a sharp increase in heroin, prescription opiate, and illicitly manufactured fentanyl abuse with overdoses tripling since the 1990s. Several states have been deemed as "high-burden" abuse states where there is a greater proportion of synthetic opiate use. During the same period that prescription limitations were initially implemented throughout the country, the fentanyl epidemic started nationwide. RECENT FINDINGS: In the setting of data demonstrating an almost fourfold increase in overdose deaths from 1999 to 2008, states began restricting access to Food and Drug Agency (FDA) approved opioid medications. Another factor further exacerbating the opioid crises is that the cost of all formulations of naloxone has increased significantly over the past several years. In order to combat the opioid epidemic, stricter prescribing practices and prescription-monitoring programs have been instituted. Also, improvements in abuse-deterrent strategies for all opioid preparations can play an important role by increasing the safety of these medications and is a major focus of the FDA.

PURPOSE OF THE REVIEW: The purpose of this manuscript is to provide a brief discussion of the current direction in pediatric regional anesthesia, highlighting both newer nerve blocks and techniques and traditional nerve blocks. RECENT FINDINGS: The number of nerve blocks performed in pediatric patients continues to increase. This growth is likely related in part to the recent focus on perioperative multimodal analgesia, in addition to growing data demonstrating safety and efficacy in this patient population. Multiple studies by the Pediatric Regional Anesthesia Network (PRAN) and the French-Language Society of Pediatric Anesthesiologists (ADARPEF) have demonstrated lack of major complications and general overall safety with pediatric nerve blocks. The growing prevalence of ultrasound-guided regional anesthesia has not only improved the safety profile, but also increased the efficacy of both peripheral nerve blocks and perineural catheters. SUMMARY: As the push for multimodal analgesia increases and the breadth of pediatric regional anesthesia continues to expand, further large prospective studies will be needed to demonstrate continued efficacy and overall safety.

There are currently new drugs being developed that have benzodiazepine properties. This review will examine remimazolam, 3-hydroxyphenazapam, adinazolam, clonazolam, and deschloroetizolam as well as other novel agents. All benzodiazepines are protein bound and only moderately lipid soluble. In addition to their baseline properties, they can be enzymatically broken down into active metabolites. The mechanism of action of these medications is related to polysynaptic pathway inhibition via direct interaction with GABA and modifiable chloride channels. The main neurological areas of involvement are primarily the amygdala and reticular activating system. Benzodiazepines are used for sedation and for adjuvants to general anesthetics and not as primary induction agents. We describe the characteristics of newer drugs being developed, including their pharmacologic profile, side effects and efficacy, as well as the most recent clinical trials and future directions in benzodiazepine development.
