Objectives: Sedation and analgesia for infants and children requiring mechanical ventilation in the PICU is uniquely challenging due to the wide spectrum of ages, developmental stages, and pathophysiological processes encountered. Studies evaluating the safety and efficacy of sedative and analgesic management in pediatric patients have used heterogeneous methodologies. The Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research (SCEPTER) IV hosted a series of multidisciplinary meetings to establish consensus statements for future clinical study design and implementation as a guide for investigators studying PICU sedation and analgesia.

Medication administration errors that take place in the home are common, especially when liquid preparations are used and complex medication schedules with multiple medications are involved; children with chronic conditions are disproportionately affected. Parents and other caregivers with low health literacy and/or limited English proficiency are at higher risk for making errors in administering medications to children in their care. Recommended strategies to reduce home medication errors relate to provider prescribing practices; health literacy-informed verbal counseling strategies (eg, teachback and showback) and written patient education materials (eg, pictographic information) for patients and/or caregivers across settings (inpatient, outpatient, emergency care, pharmacy); dosing-tool provision for liquid medication measurement; review of medication lists with patients and/or caregivers (medication reconciliation) that includes prescription and over-the-counter medications, as well as vitamins and supplements; leveraging the medical home; engaging adolescents and their adult caregivers; training of providers; safe disposal of medications; regulations related to medication dosing tools, labeling, packaging, and informational materials; use of electronic health records and other technologies; and research to identify novel ways to support safe home medication administration.

As the complexity of medicine increases, so too do the challenges with multidisciplinary communication and coordinated patient care. Anesthesiology represents a field for which there is no required study for medical students, pediatric residents, or neonatal-perinatal medicine fellows in the United States, so a neonatologist may have never received any formal training in anesthesiology (and vice versa for pediatric anesthesiologists in neonatology). In this review, we address frequently asked questions of neonatologists to anesthesiologists to better frame common issues.

In December 2016, the US Food and Drug Administration (FDA) issued a drug safety warning stating that 11 commonly used anesthetic and sedative medications had potential neurotoxic effects when used in children under the age of 3 years and in pregnant women during the third trimester. A panel presentation at the sixth biennial Pediatric Anesthesia Neurodevelopmental Assessment (PANDA) symposium addressed the FDA announcement in a session entitled "Anesthesia Exposure in Children During Surgical and Non-Surgical Procedures: How Do We Respond to the 2016 FDA Drug Safety Communication?" Panelists included representatives from pediatric anesthesiology, obstetrics, pediatric surgery, and several pediatric surgical subspecialties. Each panelist was asked to address the following questions: How has the FDA labelling change affected your clinical practice including patient discussions, timing, and frequency of procedures? Has your professional society provided any guidelines for this discussion? Has there been any discussion of this topic at your national meetings? The panelists provided important perspectives specific to each specialty, which generated a lively discussion and a detailed response from the Deputy Director of the Division of Anesthesia and Addiction of the FDA describing the FDA procedures that led to this drug safety warning.

Purpose Of Review: The purpose of this review is to summarize the current evidence regarding the impact of the exposure to anesthetic and sedative agents on neurodevelopment during the period of rapid brain growth in the first 3 years of life. Though much of the definitive data demonstrating anesthesia-induced neurotoxicity has come from studies in young animals, the focus of this review is on emerging human data.

Recent Findings: In 2016, the first prospective trials investigating the neurodevelopmental impact of early anesthetic exposure (GAS and PANDA studies) were published, both showing no significant impact on IQ from a single brief anesthetic.

Laparoscopic surgery is an evolving surgical modality in children, which has been applied to increasingly more complex surgeries and patients, including patients with renal insufficiency. These patients are particularly susceptible to the challenges that laparoscopy imposes on their altered physiology, leading to marked electrolyte disturbances, including metabolic acidosis and hyperkalemia. Hyperkalemia has the potential for marked impairment of cardiac conduction.

Purpose Of Review: The Task Force for Children's Surgical Care, an ad-hoc multidisciplinary group of invited leaders in pediatric perioperative medicine, was assembled in May 2012 to consider approaches to optimize delivery of children's surgical care in today's competitive national healthcare environment. Over the subsequent 3 years, with support from the American College of Surgeons (ACS) and Children's Hospital Association (CHA), the group established principles regarding perioperative resource standards, quality improvement and safety processes, data collection, and verification that were used to develop an ACS-sponsored Children's Surgery Verification and Quality Improvement Program (ACS CSV).

Recent Findings: The voluntary ACS CSV was officially launched in January 2017 and more than 125 pediatric surgical programs have expressed interest in verification.

Almost 30 years ago, the American Academy of Pediatrics Committee on Fetus and Newborn coauthored a policy statement strongly advocating for the use of anaesthesia in all neonates stating 'local or systemic pharmacologic agents now available permit relatively safe administration of anesthesia or analgesia to neonates undergoing surgical procedures and that such administration is indicated according to the usual guidelines for the administration of anesthesia to high-risk, potentially unstable patients'. With current techniques and advanced monitoring, preterm and full-term infants routinely undergo surgical procedures under general anaesthesia to repair congenital defects that were lethal in years past. Recent research in immature animal models, however, has shown evidence of enhanced neuroapoptosis and other signs of neurotoxicity with all of the currently used anaesthetic agents.

The Pediatric Anesthesia Neuro Development Assessment (PANDA) team at the Anesthesiology Department at Columbia University Medical Center held its fifth biennial symposium to discuss issues regarding potential neurotoxicity of anesthetic agents in pediatric patients. Overall optimal surgical timing as well as a "critical window" for surgery on a specialty specific basis are areas of focus for the American Academy of Pediatrics Surgical Advisory Panel. An ad hoc panel of pediatric surgical experts representing general surgery, urology, neurosurgery, and ophthalmology was assembled for this meeting and provided a dialogue focused on the benefits of early intervention versus potential anesthetic risk, addressing parental concerns, and the need for continued interdisciplinary collaboration in this area.

Dorsal penile nerve block is a widely used method of analgesia for infants undergoing penile surgery. Because of its potency, extended duration of action, and lack of vasoconstriction, bupivacaine remains the most commonly used local anesthetic. Rapid systemic absorption of bupivacaine, however, has been associated with profound central nervous system and cardiovascular side effects, including cardiac arrest.

Purpose Of Review: Minimally invasive approaches to pediatric surgery have become increasingly popular over the last 15 years. With the advent of robotically controlled instruments, common pediatric urologic surgeries such as pyeloplasty and ureteral reimplantation, which were previously technically challenging, are now commonly performed laparoscopically. It is important to recognize the unique physiologic considerations with this approach and how to provide safe and effective anesthesia for these procedures.
