A task force of pediatric surgical specialists with the support of The American College of Surgeons recently launched a verification program for pediatric surgery, the Children’s Surgery Verification quality improvement program, with the goal of improving pediatric surgical, procedural, and perioperative care. Included in this program are specific standards for the delivery of pediatric anesthesia care across a variety of practice settings. We review the background, available evidence, requirements for verification, and verification process and its implications for the practice of pediatric anesthesia across the country. In addition, we have included a special roundtable interview of 3 recently Children’s Surgery Verification–verified program directors to provide an up-to-date real-world perspective of this children’s surgery quality improvement program.

Abstract Background Exposure of young animals to general anesthesia causes neurodegeneration and lasting behavioral abnormalities; whether these findings translate to children remains unclear. This study used a population-based birth cohort to test the hypothesis that multiple, but not single, exposures to procedures requiring general anesthesia before age 3 yr are associated with adverse neurodevelopmental outcomes. Methods A retrospective study cohort was assembled from children born in Olmsted County, Minnesota, from 1996 to 2000 (inclusive). Propensity matching selected children exposed and not exposed to general anesthesia before age 3 yr. Outcomes ascertained via medical and school records included learning disabilities, attention-deficit/hyperactivity disorder, and group-administered ability and achievement tests. Analysis methods included proportional hazard regression models and mixed linear models. Results For the 116 multiply exposed, 457 singly exposed, and 463 unexposed children analyzed, multiple, but not single, exposures were associated with an increased frequency of both learning disabilities and attention-deficit/hyperactivity disorder (hazard ratio for learning disabilities = 2.17 [95% CI, 1.32 to 3.59], unexposed as reference). Multiple exposures were associated with decreases in both cognitive ability and academic achievement. Single exposures were associated with modest decreases in reading and language achievement but not cognitive ability. Conclusions These findings in children anesthetized with modern techniques largely confirm those found in an older birth cohort and provide additional evidence that children with multiple exposures are more likely to develop adverse outcomes related to learning and attention. Although a robust association was observed, these data do not determine whether anesthesia per se is causal.

Each year millions of young children undergo procedures requiring sedation or general anesthesia. An increasing proportion of the anesthetics used are provided to optimize diagnostic imaging studies such as magnetic resonance imaging. Concern regarding the neurotoxicity of sedatives and anesthetics has prompted the US Food and Drug Administration to change labeling of anesthetics and sedative agents warning against repeated or prolonged exposure in young children. This review aims to summarize the risk of anesthesia in children with an emphasis on anesthetic-related neurotoxicity, acknowledge the value of pediatric neuroimaging, and address this call for conversation.

BACKGROUND: Arthrogryposis syndromes are a heterogeneous group of disorders characterized by congenital joint contractures often requiring multiple surgeries during childhood to address skeletal and visceral abnormalities. Previous reports suggest that these children have increased perioperative risk, including hypermetabolic events discrete from malignant hyperthermia, difficult airway management, isolated hyperthermia, and difficult IV line placement. We sought to compare children with arthrogryposis multiplex congenita (AMC) versus the less severe, distal arthrogryposis syndromes (DAS) and to evaluate possible intraoperative hyperthermia of patients with AMC. We hypothesized that children with AMC had a greater incidence of intraoperative hyperthermia and more difficulty with airway management and IV access. METHODS: Children aged 0 to 25 years with arthrogryposis syndromes who underwent anesthesia from 1972 to 2013 were identified. The medical records were reviewed for demographics, arthrogryposis type, and anesthetic complications. AMC subjects were compared with DAS subjects. To evaluate the probability of hyperthermia and hypermetabolic responses of patients with AMC, we performed a post hoc case–control analysis. Patients with AMC were matched in a 1:2 ratio to patients without arthrogryposis to evaluate the primary outcome of maximum intraoperative temperature. RESULTS: Forty-five patients with AMC and 16 patients with DAS underwent 264 and 105 unique anesthetics, respectively. There was no significant difference in intraoperative hyperthermia or hypermetabolic events (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.36–2.47; P = .90). Children with AMC were more likely to have difficult IV access (OR, 7.1; 95% CI, 1.81–27.90; P = .005). Additional evidence suggested that difficult airway management (OR, 4.06; 95% CI, 1.01–16.39; P = .049) and hemodynamic instability (OR, 4.22; 95% CI, 1.03–17.26; P = .045) were more likely in children with AMC. From post hoc case–control analysis, there was no significant difference in the mean maximum intraoperative temperature (estimated difference +0.04°C; 95% CI, −0.14 to +0.22; P = .64) or odds of intraoperative hyperthermia (OR, 1.49; 95% CI, 0.78–2.82; P = .223) for patients with AMC compared with control subjects. CONCLUSIONS: Children with arthrogryposis syndromes present challenges to the anesthesia and surgical teams, including greater neuromuscular disease burden and challenging peripheral IV placement, with additional evidence suggesting difficult airway management and intraoperative hemodynamic instability. Although more definitive studies are warranted, we did not find evidence of increased odds of intraoperative hyperthermia or hypermetabolic responses.

During the Fifth Pediatric Anesthesia Neurodevelopmental Assessment Symposium, experts and stakeholders met to present and discuss recent advances made in the study of neurodevelopmental outcomes after exposure to anesthetic drugs in infants and children. This article summarizes the update of 5 ongoing clinical studies: General Anesthesia compared to Spinal Anesthesia, Toxicity of Remifentanil and Dexmedetomidine, Mayo Anesthesia Safety in Kids, the University of California San Francisco human cohort study, and Columbia University Medical Center Neonatal Magnetic Resonance Imaging study. The purpose of this summary is to discuss the contributions and limitations of these studies, how they fit into the published literature, and what questions remain to be answered.

SummaryBackgroundMalignant hyperthermia (MH) is a rare anesthetic pharmacogenetic disorder that can be difficult to detect in its earliest phases. Prompt treatment is known to improve outcomes. The modern anesthesia information management systems (AIMS) collect enormous amounts of data. However, data lack context and are not able to provide real‐time guidance. Utilizing our AIMS, we developed the capacity to incorporate decision support.AimsWe describe the creation and evaluation of a real‐time detection tool for MH.MethodsCases of MH from 2003 to 2013 were retrospectively reviewed to confirm the diagnosis of MH and to calculate a MH clinical grading scale score. The index cases were utilized to develop four electronic data Rules, based on endtidal CO2 (ETCO2) and temperature criteria. The Rules were then applied retrospectively to the index cases and to a full cohort of general operating room (OR) patients from January 2012 to June 2012. If criteria for possible MH was met, the detection tool generated an alert on the monitor at the patient's bedside.ResultsWe identified seven patients with confirmed MH with MH Scores ranging from 28 to 70. Using four data Rules, all of our seven index cases were captured and generated an appropriate alert. Median time from MH computer alert time to dantrolene administration time among our index cases was 23 min (IQR 17–77). There were 938 false‐positive alerts for possible MH (1.8%) when the Rules were applied to a general OR cohort of 51 579 total cases from January 2012 to June 2012.ConclusionsWe demonstrated a real‐time MH detection tool based on established physiologic criteria that is sensitive enough to capture cases suspicious for MH, while limiting false positives to prevent alarm fatigue. This has the potential to notify the provider of possible MH such that treatment may be rapidly initiated.
