This educational review presents an overview of opioid use disorder, misuse and overdose among adolescents, and the clinical implications for anesthesiologists. It provides definitions, discusses the epidemiology worldwide, (focusing on North America), and emphasizes the clinical implications of patients with chronic opioid exposure, including perioperative pain management, as well as opioid overdose and prolonged use of opioids after acute exposure. In the USA, opioid use disorder and negative outcomes related to opioids rose dramatically from 1999-2010; concomitantly heroin use and fatal overdoses have increased as heroin use is associated with the disordered use of licit opioids. Among adolescents and young adults, opioid use disorder is significant, with continued increases in disordered use specifically among young adults. Acute opioid intoxication may have multiple medical implications in addition to respiratory depression, and children are susceptible to acute intoxication via accidental ingestion of prescription opioids. Novel opioid formulations, such as acetyl fentanyl, with unpredictable pharmacology may also be present in acute intoxication. Chronically, opioid use presents challenges for safe and adequate pain management, in the presence of opioid-induced hyperalgesia and differential tolerance as well as mental health issues including depression and anxiety. Predictors of prolonged opioid use in adolescents and adults after surgery is an area of ongoing research. Young patients encountered by pediatric anesthesiologists may be involved in diversion and disordered use of opioids. Increased awareness among anesthesiologists is important, as perioperative discussions often provide an opportunity to detect at risk patients., (© 2017 John Wiley & Sons Ltd.)

Personalized medicine is the science of individualized prevention and therapy. The notion that "one size fits all" has been replaced by the idea of patient-tailored health care. Within this paradigm, the research community has turned to examine genetic predictors of disease and treatment responses. Pain researchers have produced genetic studies over the last decade that evaluate the association of genetic variability with pain sensitivity and analgesic response. While most of these studies have been conducted among cohorts of subjects of European descent, some have included other racial and ethnic groups, providing evidence of variable responses to analgesics. Simultaneously, there is an increased recognition regarding the complexity of pain research, acknowledging the additional role of epigenetic, transcriptomic, proteomic, and metabolomic factors in the development, experience, and treatment of pain. This article provides an introduction to population-specific pharmacogenetics, proteomics and other "-omics" technologies to predict drug response to pain medications in children. It aims to provide anesthesiologists with the basic knowledge to understand the potential implications of genetic and epigenetic factors managing the pain of pediatric patients.

Background: Respiratory complications were associated with half of pediatric malpractice claims from the 1970s to 1980s in the ASA Closed Claims Database. Advances in pediatric anesthesia practice have occurred in the 1980s and 1990s and may be reflected in liability trends., Methods: We reviewed 532 pediatric (age < or =16 yr) malpractice claims from our database over three decades (1973-2000), using logistic regression analysis to evaluate trends over time. Claims from 1990 to 2000 (1990s) were reviewed in detail to determine damaging events and injuries. Multiple logistic regression analysis evaluated factors associated with claims for death/brain damage (BD) compared with claims for less severe injuries., Results: From 1973 to 2000, there was a decrease in the proportion of claims for death/BD (P = 0.002) and respiratory events (P < 0.001), particularly for inadequate ventilation/oxygenation (P < 0.001). However, claims for death (41%) and BD (21%) remained the dominant injuries in pediatric anesthesia claims in the 1990s. Half of the claims in 1990-2000 involved patients 3 yr or younger and one-fifth were ASA 3-5. Cardiovascular (26%) and respiratory (23%) events were the most common damaging events. Factors associated with claims for death/BD in the 1990s when compared with claims for less severe injuries were cardiovascular events (odds ratio [OR] = 6.6, 95% confidence interval [CI] = 2.5-17.8), respiratory events (OR = 3.7, 95% CI = 1.5-9.4), and ASA status 3-5 (OR = 3.1, 95% CI = 1.3-7.8)., Conclusions: Death/BD remained the dominant injuries in pediatric anesthesia malpractice claims in the 1990s. Cardiovascular events joined respiratory events as the major sources of liability.

Over the past two years there has been increased interest in promoting research in anesthesia as an integral part of academic anesthesia practice in Colombia. The Colombian Symposium on Research in Anesthesia (organized by the Colombian Society of Anesthesiology and the Society of Anesthesiology and Reanimation of Antioquia) formulated and published guidelines to promote this effort. Despite these efforts, pediatric anesthesia is still a subspecialty in which very little research is done. In this opinion article we discuss why and how to promote research in pediatric anesthesia in Colombia. [ABSTRACT FROM AUTHOR]

The objective of this study was to determine whether the incidence of emergence agitation (EA) can be reduced by adding an additional, faster onset, non-IV analgesic, intranasal fentanyl or intramuscular (im) ketorolac to rectal acetaminophen. To compare the incidence of EA after analgesia with two agents vs acetaminophen alone in pediatric patients after bilateral myringotomy procedures (BM&T). Anesthesia for BM&T is usually performed with volatile anesthetics as a single agent without securing intravenous access. The anesthetic agent most commonly used is sevoflurane; however, EA has been reported in up to 67% of patients. Emergence agitation is distressing for parents, can impair the ability of nursing staff to adequately monitor the child, and can result in a child injuring him/herself if it is severe. A standardized anesthetic was used with oral midazolam premedication and sevoflurane for induction, and maintenance of anesthesia. All patients received 40 mg·kg rectal acetaminophen, group 1 received acetaminophen alone, group 2 received acetaminophen and 1 mcg·kg of intranasal fentanyl, and group 3 received acetaminophen and 1 mg·kg of intramuscular ketorolac. Incidence of EA was compared using chi-square test between the acetaminophen group alone vs the two-agent analgesia groups combined. There were no differences in demographic and clinical characteristics between the two groups. There were no statistically significant differences between the three groups for the incidence of EA at any time point during recovery from anesthesia nor were there any significant differences in pain scores or side effects. No significant side effects because of the administration of a second analgesic agent were reported. We conclude that two-agent analgesia is not superior to acetaminophen alone for decreasing the incidence of EA after inhalation anesthesia with sevoflurane for BM&T surgery. Our overall incidence of EA was low compared to previous studies, which could potentially have decreased our ability to detect differences between groups. [ABSTRACT FROM AUTHOR]

Tranexamic acid is an anti-fibrinolytic agent frequently used in pediatric surgery. Common side effects include nausea, flushing, and headache, but in rare instances, it may produce anaphylaxis; with only one previously reported case in a 72-year-old man. We report a case of a delayed anaphylactic reaction in a pediatric patient undergoing posterior spine fusion; and discuss the intraoperative management of the acute event, immunologic confirmation, and subsequent anesthetic approach.
