Pediatric Anesthesiology Milestones 2.0: An Update, Rationale, and Plan Forward.

Formal training in the subspecialty of pediatric anesthesiology began >60 years ago. Over the years, the duration and clinical work has varied, but what has stayed constant is a mission to develop clinically competent and professionally responsible pediatric anesthesiologists. Since accreditation in 1997, there has been additional guidance by the Accreditation Council on Graduate Medical Education (ACGME) and greater accountability to the public that we, indeed, are producing competent and professional pediatric anesthesiologists. This has been influenced by the slow evolution from time-based educational curriculum to a competency-based paradigm. As with all ACGME-accredited specialties, education leaders in pediatric anesthesiology first convened in 2014 to design specialty-specific developmental trajectories within the framework of the 6 core competencies, known as milestones, on which fellows were to be tracked during the 1-year fellowship. With 5 years of implementation, and substantial data and feedback, it has become clear that an iterative improvement was necessary to mirror the evolution of the profession. It was evident that the community required brevity and clarity in the next version of the milestones and required additional resources for assessment and faculty development. We describe here the methodology and considerations of our working group, guided by ACGME, in the rewriting of the milestones. We also provide suggestions for implementation and collaboration to support the education and assessment of pediatric anesthesiology fellows across the country.

Multicenter Population Pharmacokinetics of Fentanyl in Neonatal Surgical Patients Using Dried Blood Spot Specimen Collection Demonstrates Maturation of Elimination Clearance.

BACKGROUND: Fentanyl is widely used for analgesia and sedation in neonates, but pharmacokinetic (PK) analysis in this population has been limited by the relatively large sample volumes required for plasma-based assays. METHODS: In this multicenter observational study of fentanyl kinetics in neonates up to 42 weeks of postmenstrual age (PMA) who received fentanyl boluses and continuous infusions, dried blood spots were used for small-volume sampling. A population PK analysis was used to describe fentanyl disposition in term and preterm neonates. Covariates for the model parameters, including body weight, PMA, birth status (preterm or term), and presence of congenital cardiac disease, were assessed in a stepwise manner. RESULTS: Clearance was estimated to be greater than adult clearance of fentanyl and varied with weight. Covariate selection did not yield a significant relationship for age as a continuous or dichotomous variable (term or preterm, the latter defined as birth with PMA of <37 weeks) and clearance. CONCLUSIONS: A supra-allometric effect on clearance was determined during covariate analyses (exponential scaling factor for body weight >0.75), as has been described in population PK models that account for maturation of intrinsic clearance (here, predominantly hepatic microsomal activity) in addition to scaling for weight, both of which impact clearance in this age group.

Evolution of Accredited Pediatric Cardiac Anesthesiology Fellowship Training in the United States: A Step in the Right Direction.

Pediatric cardiac anesthesiology has developed as a subsubspecialty of anesthesiology over the past 70 years. The evolution of this specialty has led to the establishment in 2005 of a dedicated professional society, the Congenital Cardiac Anesthesia Society (CCAS). By 2010, multiple training pathways for pediatric cardiac anesthesia emerged. Eight programs in the United States offered advanced pediatric cardiac anesthesia with variable duration, ranging from 3 to 12 months. Other programs offered a combined fellow/staff position for 1 year. The need for a standardized training pathway was recognized by the Pediatric Anesthesia Leadership Council (PALC) and CCAS in 2014. Specifically, it was recommended that pediatric cardiac anesthesiology be a second, 12-month advanced fellowship following pediatric anesthesia to acquire skills unique from those acquired during a pediatric anesthesia fellowship. This was reiterated in 2018, when specific pediatric cardiac anesthesia training milestones were developed through consensus by the CCAS leadership. However, given the continuous increasing demand for well-trained pediatric cardiac anesthesiologists, it is essential that a supply of comprehensively trained physicians exists. High-quality training programs are therefore necessary to ensure excellent clinical care and enhanced patient safety. Currently, there are 23 programs offering one or more positions for 1-year pediatric cardiac anesthesia fellowship. Due to the diverse curriculum and evaluation process, formalization of the training with accreditation through the Accreditation Council for Graduate Medical Education (ACGME) was the obvious next step. Initial inquiry started in April 2020. The ACGME recognized pediatric cardiac anesthesia as a subsubspecialty in February 2021. The program requirements and milestones for the 1-year fellowship training were developed in 2021 and 2022. This special article reviews the history of pediatric cardiac anesthesia training, the ACGME application process, the development of program requirements and milestones, and implementation.

Advanced wireless monitoring for children in the cardiac perioperative setting.

INTRODUCTION: More than 40,000 children undergo surgical interventions annually for the treatment of congenital heart defects. Intraoperative and postoperative vital sign monitoring is a cornerstone of pediatric care. METHODS: A single-arm prospective observational study was performed. Pediatric patients undergoing a procedure with a planned admission to the Cardiac Intensive Care Unit at Lurie Children's Hospital (Chicago, IL) were eligible for enrollment. Participant vital signs were monitored using standard equipment and an FDA-cleared experimental device (ANNE® ) consisting of a wireless patch positioned at the suprasternal notch and index finger or foot. The primary goal of the study was to assess real-world feasibility of wireless sensors in pediatric patients with congenital cardiac defects. RESULTS: A total of 13 patients were enrolled, ranging in age from 4 months to 16 years with a median age of 4 years. Overall, 54% (n = 7) were female and the most common anomaly in the cohort was an atrial septal defect (n = 6). The mean admission length was 3 days (range 2-6), resulting in more than 1000 h of vital sign monitoring (⟩60,000 data points). Bland-Altman plots were generated for heart rate and respiratory rate to assess beat-to-beast differences between the standard equipment and the experimental sensors. CONCLUSIONS: Novel, wireless, flexible sensors demonstrated comparable performance to standard monitoring equipment in a cohort of pediatric patients with congenital cardiac heart defects undergoing surgery.

Anesthesia and Developing Brains: Unanswered Questions and Proposed Paths Forward.

Anesthetic agents disrupt neurodevelopment in animal models, but evidence in humans is mixed. The morphologic and behavioral changes observed across many species predicted that deficits should be seen in humans, but identifying a phenotype of injury in children has been challenging. It is increasingly clear that in children, a brief or single early anesthetic exposure is not associated with deficits in a range of neurodevelopmental outcomes including broad measures of intelligence. Deficits in other domains including behavior, however, are more consistently reported in humans and also reflect findings from nonhuman primates. The possibility that behavioral deficits are a phenotype, as well as the entire concept of anesthetic neurotoxicity in children, remains a source of intense debate. The purpose of this report is to describe consensus and disagreement among experts, summarize preclinical and clinical evidence, suggest pathways for future clinical research, and compare studies of anesthetic agents to other suspected neurotoxins.

Patient and operative factors associated with unanticipated intensive care admission and outcomes following posterior fossa decompressions in children: A retrospective study.

INTRODUCTION: Posterior fossa decompression for Chiari I Malformation is a common pediatric neurosurgical procedure. We sought to identify the impact of anesthesia-related intraoperative complications on unanticipated admission to the intensive care unit and outcomes following posterior fossa decompression. METHODS: Medical records of all patients <18 years who underwent surgery for Chiari I malformation between 1/1/09 and 1/31/21 at the Ann & Robert H. Lurie Children's Hospital of Chicago were included. Records were reviewed for patient characteristics, anesthesia-related intraoperative complications, postoperative complications, and surgical outcomes. The primary outcome was the incidence of unanticipated admission to the intensive care unit, and the primary variable of interest was an anesthesia-related intraoperative complication. Patient, surgical characteristics, and year of surgery were also compared between patients with and without an unanticipated admission to the intensive care unit, and a multi-variable adjusted estimate of odds of unanticipated admission to the intensive care unit admission following an anesthesia-related intraoperative complication was performed. Secondary outcomes included anesthesia factors associated with an anesthesia-related intraoperative event, and postoperative complications and surgical outcomes between patients admitted to the intensive care unit and those who were not. RESULTS: Two hundred ninety-six patients with Chiari I Malformation were identified. Clinical characteristics associated with an unanticipated admission to the intensive care unit were younger age, American Society of Anesthesiologist (ASA) physical status >2 and an anesthesia-related intraoperative complication. 29 anesthesia-related intraoperative complications were observed in 25 patients (8.4%). Two of 25 patients (8%) with an anesthesia-related intraoperative complication compared with 3 of 271 (1%) patients without anesthesia-related intraoperative complication had an unanticipated admission to the intensive care unit, odds ratio 7.8 (95% CI 1.2-48.8, p = .010). When adjusted for age, sex, ASA physical status, presenting symptoms, concomitant syringomyelia, previous decompression surgery and year of surgery, the odds ratio for an unanticipated admission to the intensive care unit following an anesthesia-related intraoperative complication was 5.9 (95% CI 0.51-59.6, p = .149). There were no differences in surgical outcomes between patients with or without an unanticipated admission to the intensive care unit. CONCLUSION: Our study demonstrates that although anesthesia-related intraoperative complications during posterior fossa decompression are infrequent, they are associated with an increased risk of an unanticipated admission to the intensive care unit.

First-Year Results of the American Board of Anesthesiology's Objective Structured Clinical Examination for Initial Certification.

In 2018, the American Board of Anesthesiology (ABA) became the first US medical specialty certifying board to incorporate an Objective Structured Clinical Examination (OSCE) into its initial certification examination system. Previously, the ABA's staged examination system consisted of 2 written examinations (the BASIC and ADVANCED examinations) and the Standardized Oral Examination (SOE). The OSCE and the existing SOE are now 2 separate components of the APPLIED Examination. This report presents the results of the first-year OSCE administration. A total of 1410 candidates took both the OSCE and the SOE in 2018. Candidate performance approximated a normal distribution for both the OSCE and the SOE, and was not associated with the timing of the examination, including day of the week, morning versus afternoon session, and order of the OSCE and the SOE. Practice-based Learning and Improvement was the most difficult station, while Application of Ultrasonography was the least difficult. The correlation coefficient between SOE and OSCE scores was 0.35 ([95% confidence interval {CI}, 0.30-0.39]; P < .001). Scores for the written ADVANCED Examination were modestly correlated with scores for the SOE (r = 0.29 [95% CI, 0.25-0.34]; P < .001) and the OSCE (r = 0.15 [95% CI, 0.10-0.20]; P < .001). Most of the candidates who failed the SOE passed the OSCE, and most of the candidates who failed the OSCE passed the SOE. Of the 1410 candidates, 77 (5.5%) failed the OSCE, 155 (11.0%) failed the SOE, and 25 (1.8%) failed both. Thus, 207 (14.7%) failed at least 1 component of the APPLIED Examination. Adding an OSCE to a board certification examination system is feasible. Preliminary evidence indicates that the OSCE measures aspects of candidate abilities distinct from those measured by other examinations used for initial board certification.

Development of an Objective Structured Clinical Examination as a Component of Assessment for Initial Board Certification in Anesthesiology.

With its first administration of an Objective Structured Clinical Examination (OSCE) in 2018, the American Board of Anesthesiology (ABA) became the first US medical specialty certifying board to incorporate this type of assessment into its high-stakes certification examination system. The fundamental rationale for the ABA's introduction of the OSCE is to include an assessment that allows candidates for board certification to demonstrate what they actually "do" in domains relevant to clinical practice. Inherent in this rationale is that the OSCE will capture competencies not well assessed in the current written and oral examinations-competencies that will allow the ABA to judge whether a candidate meets the standards expected for board certification more properly. This special article describes the ABA's journey from initial conceptualization through first administration of the OSCE, including the format of the OSCE, the process for scenario development, the standardized patient program that supports OSCE administration, examiner training, scoring, and future assessment of reliability, validity, and impact of the OSCE. This information will be beneficial to both those involved in the initial certification process, such as residency graduate candidates and program directors, and others contemplating the use of high-stakes summative OSCE assessments.

Impact of preoperative hyponatraemia on paediatric perioperative mortality.

BACKGROUND: Preoperative hyponatraemia is an independent risk factor for postoperative mortality in adults. To our knowledge, this has not been investigated in children. METHODS: Using data from the 2014 and 2015 data sets of the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-P), we conducted a retrospective study of children undergoing surgery. The primary outcome was 30-day all-cause mortality. The secondary outcomes of interest were postoperative seizure within 30 days and prolonged length of stay. To identify any independent association between preoperative hyponatraemia, defined as mild (serum sodium of 131-135 mEq L-1) or severe (≤130 mEq L-1), and death, postoperative seizures, or prolonged length of stay, multivariable logistic regression models were generated. RESULTS: A total of 152 894 patients were identified, and of these 35 291 were included in the final analysis. Preoperative hyponatraemia was present in 5422 patients or 15.4% of the final cohort. There were 432 (0.80%) deaths at 30 days. Compared with patients with a normal preoperative sodium concentration, those with mild (P=0.003; odds ratio [OR]: 1.59; 95% confidence interval [CI]: 1.17-2.18) and severe (P=0.002; OR: 2.16; 95% CI: 1.32-3.54) hyponatraemia had increased rates of death, after adjusting for co-morbidity and procedural complexity. Both mild (P<0.001; OR: 1.53; 95% CI: 1.42-1.65) and severe (P<0.001; OR: 1.51; 95% CI: 1.19-1.93) hyponatraemia were independently associated with prolonged length of stay, after adjusting for relevant co-variates. CONCLUSIONS: This retrospective analysis identified an association between preoperative hyponatraemia and perioperative mortality and length of stay in paediatric patients.

Regional Analgesia Added to General Anesthesia Compared With General Anesthesia Plus Systemic Analgesia for Cardiac Surgery in Children: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

BACKGROUND: The aim of this systematic review was to compare the effects of regional analgesic (RA) techniques with systemic analgesia on postoperative pain, nausea and vomiting, resources utilization, reoperation, death, and complications of the analgesic techniques in children undergoing cardiac surgery. METHODS: A search was done in May 2018 in PubMed, Embase, and the Cochrane Central Register of Controlled Trials for randomized controlled trials comparing RA techniques with systemic analgesia. Risks of bias of included trials were judged with the Cochrane tool. Data were analyzed with fixed- (I(2) < 25%) or random-effects models (I(2) ≥ 25%). The quality of evidence was graded according to the Grading of Recommendations Assessment, Development, and Evaluation working group scale. RESULTS: We included 14 randomized controlled trials with 605 participants (312 to RA and 293 to the comparator). RA reduces pain up to 24 hours after surgery. At 6-8 hours after surgery, the standardized mean difference was -0.81 (95% confidence interval [CI], -1.22 to -0.40; low-quality evidence). We did not find a difference for nausea and vomiting (risk ratio [RR], 0.89; 95% CI, 0.61-1.31; very low-quality evidence), duration of tracheal intubation (standardized mean difference, -0.18; 95% CI, -0.40 to 0.05; low-quality evidence), intensive care unit length of stay (mean difference, -0.10 hours; 95% CI, -1.31 to 1.12 hours; low-quality evidence), hospital length of stay (mean difference, -0.02 days; 95% CI, -1.16 to 1.12 days; low-quality evidence), reoperation (RR, 0.76; 95% CI, 0.17-3.28; low-quality evidence), death (RR, 0.50; 95% CI, 0.05-4.94; low-quality evidence), and respiratory depression (RR, 2.06; 95% CI, 0.20-21.68; very low-quality evidence). No trial reported signs of local anesthetic toxicity or lasting neurological or infectious complications related to the RA techniques. One trial reported 1 transient ipsilateral episode of diaphragmatic paralysis with intrapleural analgesia that resolved with cessation of local anesthetic administration. CONCLUSIONS: Compared to systemic analgesia, RA techniques reduce postoperative pain up to 24 hours in children undergoing cardiac surgery. Currently, there is no evidence that RA for pediatric cardiac surgery has any impact on major morbidity and mortality. These results should be interpreted cautiously because they represent a meta-analysis of small and heterogeneous studies. Further studies are needed.

The use of ultrasound guidance for perioperative neuraxial and peripheral nerve blocks in children.

BACKGROUND: The use of ultrasound guidance for regional anaesthesia has become popular over the past two decades. However, it is not recognized by all experts as an essential tool, perhaps because it is unclear whether ultrasound reduces the risk of severe neurological complications, and the cost of an ultrasound machine (USD 22,000) is substantially higher than the cost of other tools. This review was published in 2016 and updated in 2019. OBJECTIVES: To determine whether ultrasound guidance offers any clinical advantage when neuraxial and peripheral nerve blocks are performed in children in terms of decreasing failure rate or the rate of complications. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and two trial registers up to March 2018 together with reference checking to identify additional studies and contacted study authors to obtain additional trial information. SELECTION CRITERIA: We included all parallel randomized controlled trials that evaluated the effects of ultrasound guidance used when a regional blockade technique was performed in children. We included studies performed in children (≤ 18 years of age) undergoing any type of surgical procedure (open or laparoscopic), for which a neuraxial (spinal, epidural, caudal, or combined spinal and epidural) or peripheral nerve block (any peripheral nerve block including fascial (fascia iliaca, transversus abdominis plane, rectus sheath blocks) or perivascular blocks), for surgical anaesthesia (alone or in combination with general anaesthesia) or for postoperative analgesia, was performed with ultrasound guidance. We excluded studies in which regional blockade was used to treat chronic pain.We included studies in which ultrasound guidance was used to perform the technique in real time (in-plane or out-of-plane), as pre-scanning before the procedure or to evaluate the spread of the local anaesthetic so the position of the needle could be adjusted or the block complemented. For control groups, any other technique used to perform the block including landmarks, loss of resistance (air or fluid), click, paraesthesia, nerve stimulator, transarterial, or infiltration was accepted. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. Our primary outcomes were failed blocks, pain scores at one hour after surgery, and block duration. Secondary outcomes included time to perform the block, number of needle passes, and minor and major complications. We used GRADE to assess the quality of evidence for each outcome. MAIN RESULTS: We included 33 trials with a total of 2293 participants from 0.9 to 12 (mean or median) years of age. Most trials were at low risk of selection, detection, attrition, and reporting bias, however the lack of blinding of participants and personnel caring for participants resulted in 25 trials being judged as at high or unclear risk of bias. We identified five ongoing trials.Ultrasound guidance probably reduces the risk of failed block (risk difference (RD) -0.16, 95% confidence interval (CI) -0.25 to -0.07; 22 trials; 1789 participants; moderate-quality evidence). When ultrasound guidance was used, there was a small to moderate reduction in pain one hour after surgery, equivalent to a reduction of 1.3 points on the revised Bieri FACES pain scale (scale; 0 = no pain, 10 = maximal pain) (standardized mean difference (SMD) -0.41, 95% CI -0.74 to -0.07 (medium effect size); 15 trials; 982 participants; moderate-quality evidence). Ultrasound guidance increases block duration by the equivalent of 42 minutes (SMD 1.24, 95% CI 0.72 to 1.75; 10 trials; 460 participants; high-quality evidence).There is probably little or no difference in the time taken to perform the block (SMD -0.46, 95% CI -1.06 to 0.13; 9 trials; 680 participants; moderate-quality evidence). It is uncertain whether the number of needle passes required is reduced with the use of ultrasound guidance (SMD -0.63, 95% CI -1.08 to -0.18; 3 trials; 256 participants; very low-quality evidence).There were no occurrences of major complications in either the intervention or control arms of the trials (cardiac arrest from local anaesthetic toxicity (22 trials; 1576 participants; moderate-quality evidence); lasting neurological injury (19 trials; 1250 participants; low-quality evidence)).There may be little of no difference in the risk of bloody puncture (RD -0.02, 95% CI -0.05 to 0.00; 13 trials; 896 participants; low-quality evidence) or transient neurological injury (RD -0.00, 95% CI -0.01 to 0.01; 18 trials; 1230 participants; low-quality evidence). There were no occurrences of seizure from local anaesthetic toxicity (22 trials; 1576 participants; moderate-quality evidence) or block infections without neurological injury (18 trials; 1238 participants; low-quality evidence). AUTHORS' CONCLUSIONS: Ultrasound guidance for regional blockade in children probably decreases the risk of failed block. It increases the duration of the block and probably decreases pain scores at one hour after surgery. There may be little or no difference in the risks of some minor complications. The five ongoing studies may alter the conclusions of the review once published and assessed.

Postoperative epidural analgesia versus systemic analgesia for thoraco-lumbar spine surgery in children.

BACKGROUND: Spine surgery may be associated with severe acute postoperative pain. Compared with systemic analgesia alone, epidural analgesia may offer better pain control. However, epidural analgesia has sometimes been associated with rare but serious complications. Therefore, it is critical to quantify the real benefits of epidural analgesia over other modes of pain treatment. OBJECTIVES: To assess the effectiveness and safety of epidural analgesia compared with systemic analgesia for acute postoperative pain control after thoraco-lumbar spine surgery in children. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and Cumulative Index to Nursing and Allied Health Literature on 14 November 2018, together with the references lists of related reviews and retained trials, and two trials registers. SELECTION CRITERIA: We included all randomized controlled trials performed in children undergoing any type of thoraco-lumbar spine surgery comparing epidural analgesia with systemic analgesia for postoperative pain. We applied no language or publication status restriction. DATA COLLECTION AND ANALYSIS: We assessed risk of bias of included trials using the Cochrane tool. We analysed data using random-effects models. We rated the quality of the evidence according to the GRADE scale. MAIN RESULTS: We included 11 trials (559 participants) in the review, and seven trials (249 participants) in the analysis: 140 participants received epidural analgesia and 109 received systemic analgesia.Most studies included adolescents. Three trials included in the analysis contained some participants older than 18 years. The types of surgery were posterior spinal fusion for idiopathic scoliosis (nine trials), anterior correction for idiopathic scoliosis (one trial), or selective dorsal rhizotomy in children with cerebral palsy (one trial). The mean numbers of vertebrae operated on were between nine and 14.5 and the mean numbers of spinal levels were between three and four and a half. The length of surgery varied between three and six and a half hours.Compared with systemic analgesia, epidural analgesia reduced pain at rest at all time points. At six to eight hours, the mean pain score on a 0 to 10 scale with systemic analgesia was 3.1 (standard deviation 0.7) and with epidural analgesia was -1.32 points (95% confidence interval (CI) -1.83 to -0.82; 4 studies, 116 participants; moderate-quality evidence). At 72 hours, the mean pain score with epidural analgesia was equivalent to a -0.8 point reduction on a 0 to 10 scale (standardized mean difference (SMD) -0.65, 95% CI -1.19 to -0.10; 5 studies, 157 participants; moderate-quality evidence).Return of gastrointestinal functionThere was no difference for nausea and vomiting between groups (risk ratio (RR) 0.87, 95% CI 0.58 to 1.30; 6 studies, 215 participants; low-quality evidence). One study found epidural analgesia with local anaesthetics may have increased the number of participants who had their first flatus within 48 hours (RR 1.63, 95% CI 1.08 to 2.47; 30 participants; very low-quality evidence). Two studies found epidural analgesia with local anaesthetics may have increased the number of participants in whom first bowel movement occurred within 48 hours (RR 11.52, 95% CI 2.36 to 56.26; 60 participants; low-quality evidence). It was uncertain whether epidural analgesia reduced the time to first bowel movement (MD 0.09 days, 95% CI -0.32 to 0.50; 1 study, 60 participants; very low-quality evidence) and time to first liquid ingestion following epidural infusion of an opioid alone or a local anaesthetic plus an opioid (mean difference (MD) -5.02 hours, 95% CI -13.15 to 3.10; 2 studies, 56 participants; very low-quality evidence). Epidural analgesia with local anaesthetics may have increased the risk of having first solid food ingestion within 48 hours (RR 7.00, 95% CI 1.91 to 25.62; 1 study, 30 participants; very low-quality evidence).Secondary outcomesIt was uncertain whether there was a difference in time to ambulate (MD 0.08 days, 95% CI -0.24 to 0.39; 1 study, 60 participants; very low-quality evidence) and hospital length of stay (MD -0.29 days, 95% CI -0.69 to 0.10; 2 studies, 89 participants; very low-quality evidence). Two studies found participants were more satisfied when treated with epidural analgesia (MD 1.62 on a scale from 0 to 10, 95% CI 1.26 to 1.97; 60 participants; very low-quality evidence). It was unclear whether there was a difference in parent satisfaction for epidural analgesia with an opioid alone (MD 0.60, 95% CI -0.81 to 2.01; 1 trial, 27 participants; very low-quality evidence).ComplicationsIt was uncertain whether there was a difference in the risk of complications such as: respiratory depression (risk difference (RD) -0.05, 95% CI -0.16 to 0.05; 4 studies, 126 participants; very low-quality evidence); wound infection (RD 0.01, 95% CI -0.05 to 0.08; 2 trials, 93 participants; very low-quality evidence); epidural abscess (RD 0, 95% CI -0.05 to 0.05; 3 trials, 120 participants; very low-quality evidence); and neurological complications (RD 0.01, 95% CI -0.04 to 0.06; 4 studies, 151 participants; very low-quality evidence). AUTHORS' CONCLUSIONS: There is moderate- and low-quality evidence that there may be a small additional reduction in pain up to 72 hours after surgery with epidural analgesia compared with systemic analgesia. Two very small studies showed epidural analgesia with local anaesthetic alone may accelerate the return of gastrointestinal function. The safety of this technique in children undergoing thoraco-lumbar surgery is uncertain due to the very low-quality of the evidence. The study in 'Studies awaiting classification' may alter the conclusions of the review once assessed.

Predictive factors for adverse outcomes in pediatric patients undergoing low-risk skin and soft tissue surgery: A database analysis of 6730 patients.

BACKGROUND: There is a paucity of data regarding risk stratification of pediatric patients presenting for low-risk skin and soft tissue surgery. AIMS: We sought to determine the incidence and independent predictors of postoperative complications and unplanned 30-day readmission in a cohort of children undergoing low-risk skin and soft tissue surgery. METHODS: The study included pediatric patients who underwent minor procedures of the skin and soft tissue at continuously enrolled American College of Surgeons National Surgical Quality Improvement Program Pediatric hospitals over a two-year period. The primary outcome was a 30-day postoperative complication composite. The secondary outcome was unplanned 30-day readmission. RESULTS: The final analysis included 6,730 patients. There were a total of 170 postoperative complications among 152 patients (2.23%) with the majority of complications being either wound-related or postoperative mechanical ventilation. The independent predictors for an increased risk of postoperative complication were American Society of Anesthesiologists classification ≥3 and nutritional deficiency. There were 41 unplanned readmissions (0.61%). The presence of a postoperative wound complication or a postoperative pulmonary complication during the index hospital stay was an independent risk factor for unplanned 30-day readmission. CONCLUSION: Pediatric patients with American Society of Anesthesiologists classification ≥3 and nutritional deficiency undergoing low-risk surgery are at risk for the development of postoperative complications. Patients who develop wound and postoperative pulmonary complications are at higher risk for unplanned 30-day readmission. Identification of these higher risk patients may allow the anesthesiologist to implement targeted therapies to minimize the likelihood of occurrence of these complications.

Updates on pediatric regional anesthesia safety data.

PURPOSE OF REVIEW: The clinical practice of anesthesia continues to evolve and grow toward increasing quality and safety while improving the patient and family perioperative experience. Within the realm of pediatric anesthesia, advances in regional anesthesia techniques are important part in this aim. RECENT FINDINGS: The aim of this review is to provide an update on recent advances in pediatric regional anesthesia. This includes an emphasis on safety data from large datasets that previously were not available. In addition, novel blocks within pediatric regional anesthesia will be described. SUMMARY: Large data sets have given clinical providers information into the practice of regional anesthesia. It has confirmed the safety of common regional anesthetic techniques in addition to providing guidance to improving outcomes for children.

Anesthetic neurotoxicity--clinical implications of animal models.

Some anesthetics and sedatives have been shown to cause neurotoxic effects in laboratory animals. The FDA collaboration SmartTots recommends undertaking large-scale clinical studies and avoiding nonurgent surgical procedures requiring anesthesia in children younger than 3 years of age.

Complications in Pediatric Regional Anesthesia: An Analysis of More than 100,000 Blocks from the Pediatric Regional Anesthesia Network.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Complications in pediatric regional anesthesia are rare, so a large sample size is necessary to quantify risk. The Pediatric Regional Anesthesia Network contains data on more than 100,000 blocks administered at more than 20 children's hospitals. This study analyzed the risk of major complications associated with regional anesthesia in children. METHODS: This is a prospective, observational study of routine clinical practice. Data were collected on every regional block placed by an anesthesiologist at participating institutions and were uploaded to a secure database. The data were audited at multiple points for accuracy. RESULTS: There were no permanent neurologic deficits reported (95% CI, 0 to 0.4:10,000). The risk of transient neurologic deficit was 2.4:10,000 (95% CI, 1.6 to 3.6:10,000) and was not different between peripheral and neuraxial blocks. The risk of severe local anesthetic systemic toxicity was 0.76:10,000 (95% CI, 0.3 to 1.6:10,000); the majority of cases occurred in infants. There was one epidural abscess reported (0.76:10,000, 95% CI, 0 to 4.8:10,000). The incidence of cutaneous infections was 0.5% (53:10,000, 95% CI, 43 to 64:10,000). There were no hematomas associated with neuraxial catheters (95% CI, 0 to 3.5:10,000), but one epidural hematoma occurred with a paravertebral catheter. No additional risk was observed with placing blocks under general anesthesia. The most common adverse events were benign catheter-related failures (4%). CONCLUSIONS: The data from this study demonstrate a level of safety in pediatric regional anesthesia that is comparable to adult practice and confirms the safety of placing blocks under general anesthesia in children.

SmartTots Update Regarding Anesthetic Neurotoxicity in the Developing Brain.

SmartTots (http://smarttots.org/) represents a public-private partnership between the International Anesthesia Research Society and the US Food and Drug Administration. Over the past 7 years, SmartTots has worked in collaboration with various stakeholders to determine whether anesthetic drugs have detrimental effects on the developing brain. SmartTots has funded clinical and preclinical studies, organized meetings, served as a repository of peer-reviewed information, and facilitated the development of consensus-based statements. Here, we report advances in the field of anesthetic neurotoxicity and provide an update on SmartTots' activities. Clinical studies have provided some reassurance that a brief exposure to anesthetic drugs does not cause overt, persistent cognitive deficits. New recommendations aim to increase the reproducibility and "clinical relevance" of data from studies of laboratory animals. Overall, the field has advanced substantially; however, it remains paramount to definitively resolve whether anesthetic drugs are neurotoxic to the immature brain. The results of SmartTots efforts will either ally unwarranted fears or substantially change pediatric anesthetic practice and prompt studies to identify neuroprotective strategies.

Pediatric Anesthesiology Fellows' Perception of Quality of Attending Supervision and Medical Errors.

BACKGROUND: Appropriate supervision has been shown to reduce medical errors in anesthesiology residents and other trainees across various specialties. Nonetheless, supervision of pediatric anesthesiology fellows has yet to be evaluated. The main objective of this survey investigation was to evaluate supervision of pediatric anesthesiology fellows in the United States. We hypothesized that there was an indirect association between perceived quality of faculty supervision of pediatric anesthesiology fellow trainees and the frequency of medical errors reported. METHODS: A survey of pediatric fellows from 53 pediatric anesthesiology fellowship programs in the United States was performed. The primary outcome was the frequency of self-reported errors by fellows, and the primary independent variable was supervision scores. Questions also assessed barriers for effective faculty supervision. RESULTS: One hundred seventy-six pediatric anesthesiology fellows were invited to participate, and 104 (59%) responded to the survey. Nine of 103 (9%, 95% confidence interval [CI], 4%-16%) respondents reported performing procedures, on >1 occasion, for which they were not properly trained for. Thirteen of 101 (13%, 95% CI, 7%-21%) reported making >1 mistake with negative consequence to patients, and 23 of 104 (22%, 95% CI, 15%-31%) reported >1 medication error in the last year. There were no differences in median (interquartile range) supervision scores between fellows who reported >1 medication error compared to those reporting ≤1 errors (3.4 [3.0-3.7] vs 3.4 [3.1-3.7]; median difference, 0; 99% CI, -0.3 to 0.3; P = .96). Similarly, there were no differences in those who reported >1 mistake with negative patient consequences, 3.3 (3.0-3.7), compared with those who did not report mistakes with negative patient consequences (3.4 [3.3-3.7]; median difference, 0.1; 99% CI, -0.2 to 0.6; P = .35). CONCLUSIONS: We detected a high rate of self-reported medication errors in pediatric anesthesiology fellows in the United States. Interestingly, fellows' perception of quality of faculty supervision was not associated with the frequency of reported errors. The current results with a narrow CI suggest the need to evaluate other potential factors that can be associated with the high frequency of reported errors by pediatric fellows (eg, fatigue, burnout). The identification of factors that lead to medical errors by pediatric anesthesiology fellows should be a main research priority to improve both trainee education and best practices of pediatric anesthesia.

Blood Bupivacaine Concentrations After a Combined Single-Shot Sciatic Block and a Continuous Femoral Nerve Block in Pediatric Patients: A Prospective Observational Study.

We evaluated blood bupivacaine concentrations in children having a single-shot sciatic and continuous femoral blocks after anterior cruciate ligament repair. Dried blood spot samples were analyzed for bupivacaine levels at 0, 5, 15, 30, 60, and 120 minutes and 4, 24, and 48 hours. The highest 99% upper confidence interval limit was 135 ng/mL at the 4-hour evaluation point. The 99% upper confidence interval was below potentially toxic levels (1500 ng/mL) across all sampling times. The risk of local anesthetic toxicity in pediatric patients receiving single-shot sciatic and continuous femoral nerve blocks is very low.
