Abstract
Introduction As the primary source of smoke exposure is in the home, the smoking behaviors of parents and other caregivers are key determinants of a child's exposure to secondhand smoke. The perioperative period offers an opportunity to discuss smoking cessation strategies. Methods This prospective study included 97 parents or caregivers of patients undergoing dental surgery. Caregivers were surveyed in the dental waiting room during the preoperative phase. The primary aim was to determine the feasibility of using the preoperative encounter to offer smoking cessation resources to parents of pediatric patients. The secondary aim was to compare willingness to receive smoking cessation resources according to the knowledge of the risks of secondhand smoking (ie, being aware of secondhand smoking and knowing that it posed a risk to their child). Results Awareness of risks due to secondhand smoking was 65% in the overall cohort and 58% among current smokers (P=0.284 vs nonsmokers). Among smokers in our study, only a small percentage (12%) were interested in smoking cessation help. Knowledge of the risks of secondhand smoke may not be sufficient for smokers to express willingness to receive help. Conclusion The outpatient clinic may be a teaching opportunity for smoking cessation for caregivers. However, we found that only a small percentage of caregivers were interested in receiving information about smoking cessation. This was despite the fact they were aware of the potential adverse effects of secondhand smoke on their children.

Abstract
In utero, the ductus venosus connects the left portal vein to the inferior vena cava, allowing a portion of the venous blood to bypass the liver and return to the heart. After birth, the ductus venosus closes due to changes in intracardiac pressures and a decrease in endogenous prostaglandins. Failure of the ductus venosus to close may result in galactosemia, hypoxemia, encephalopathy with hyperammonia, and hepatic dysfunction. We report an infant with complex congenital heart disease (CHD) who developed coagulopathy and hyperammonia during the preoperative period secondary to patent ductus venosus (PDV). Previous reports of PDV in CHD are presented, its etiology and clinical consequences reviewed, and options for therapeutic treatment discussed.

Abstract
BACKGROUND Understanding how survey methodology and quality measures are associated with progress from abstract presentation to manuscript publication can help optimize the design of survey research in anesthesiology, and enhance respondents' confidence in the value of survey participation. AIMS The aim of this study was to determine if adherence to survey method recommendations and attainment of high response rates are associated with faster progress to publication among abstracts initially presented at anesthesiology society meetings. METHODS Abstracts from the American Society of Anesthesiologists' (ASA) Annual Meeting, Association of Anaesthetists of Great Britain and Ireland (AAGBI) Annual Congress, and the International Anesthesia Research Society (IARS) Annual Meeting from 2011-2014 were reviewed. Abstracts reporting original survey data collection were included in a systematic search for resulting publications in peer-reviewed academic journals. Cox proportional hazards regression was used to analyze progress to publication. RESULT Ninety-nine ASA, 76 AAGBI, and 30 IARS abstracts met inclusion criteria. Among these abstracts, 43 (43%) from ASA, none from AAGBI, and 7 (23%) from IARS have been published as original research articles or brief reports. Surveying patients or caregivers, as opposed to medical professionals, was associated with increased likelihood of publication (hazard ratio [HR] = 4.4, 95% confidence interval [CI]: 1.6, 12.4, P = 0.005) as was a larger sample size (eg, >500 vs <100; HR = 12.9, 95% CI: 3.8, 43.6, P < 0.001). CONCLUSIONS While abstract presentation facilitates rapid dissemination of survey research findings, the impact and utility of such studies may be limited until a full manuscript is published. In our review, 25% of abstracts presenting survey data at major anesthesiology meetings were eventually published. Larger sample sizes and a target population of patients or caregivers increased the likelihood of survey research being published in full form.

Abstract
Background When managing patients with a difficult airway, supraglottic airways (SGAs) have been used as rescue devices or to serve as a conduit for endotracheal intubation. The current study compares various clinical outcomes, including the bronchoscopic view of the glottis when using 2 SGAs, the Air-Q® laryngeal mask airway (LMA) and the i-gel® SGA, in pediatric patients. Methods Patients ≤18 years of age were prospectively randomized to receive either the Air-Q® LMA or the i-gel® SGA. Following SGA placement, a flexible fiberoptic bronchoscope was inserted through the SGA to visualize the glottis. Time taken to obtain the bronchoscopic view and place the SGA, and the ability to seal the airway at 20 cmH2O were compared. The bronchoscopic view obtained was graded as follows: 1) glottic aperture seen completely; 2) glottic aperture seen partially with visual obstruction <50%; 3) glottic aperture seen, but visual obstruction >50%; and 4) glottic aperture not seen. Results Fifty patients were enrolled and 48 (22/26 male/female) were included in the analysis. Median age was 13 years (IQR: 7, 16) and median weight was 49 kg (IQR: 25, 70). The Air-Q® LMA and i-gel® SGA groups did not differ in device placement time (median of 19 vs 21 seconds; 95% CI of difference in medians: - 2 to 7; P=0.331), the time to achieve fiberoptic view of the glottis (median of 25 vs 21 seconds; 95% CI of difference: - 9 to 8; P=0.489) or the grade of the bronchoscopic view of the airway. Eight Air-Q® and 6 i-gel® supraglottic devices sealed the airway at 20 cmH2O. Discussion The time required for successful placement of the SGA, the time required for bronchoscopic view, and the quality of bronchoscopic view through the Air-Q® LMA and the i-gel® SGA did not differ.

Abstract
Socioeconomic disparities in access to care coordination have been noted among children with special health care needs (CSHCN). Following recent policy developments and technological innovation, care coordination has become more widespread, possibly leading to reduced disparity in care coordination access. This study investigates whether child and household characteristics remain associated with unmet need for care coordination among CSHCN. CSHCN (aged <18 years) requiring ≥2 types of health services in the past year were identified in the 2016 National Survey of Children's Health (NSCH). Care coordination was defined as help with arranging the child's care among different doctors or services. Children were classified as not needing care coordination, receiving sufficient care coordination (met need), or needing but not receiving care coordination (unmet need). Weighted multinomial logistic regression examined the association of child characteristics with this outcome. The analysis included 5622 children with no need for care coordination, 1466 with a met need, and 980 with unmet needs. Children with mental health conditions were more likely to have unmet rather than met needs for care coordination (odds ratio = 4.1; 95% confidence interval: 2.7, 6.1; P < 0.001). After multivariable adjustment, race/ethnicity, income, family structure, insurance coverage, place of birth, and use of English in the home were not associated with having unmet rather than met needs for care coordination. Among CSHCN, the latest data from NSCH reveal no evidence of previously described socioeconomic disparities in access to care coordination. Nevertheless, unmet needs for care coordination remain prevalent, especially among children with mental health conditions.

Abstract
OBJECTIVE Rapid administration of fluid remains a cornerstone in treatment of shock and when caring for trauma patients. A range of devices and technologies are available to hasten fluid administration time. While new devices may optimize fluid delivery times, impact on subjective experience compared to traditional methods is poorly documented. Our study evaluated administration time and provider experience using two unique methods for fluid administration. MATERIALS AND METHODS Prospective comparison of objective and subjective outcomes using a novel infusion device (LifeFlow® Rapid Infuser) and the traditional push-pull syringe method in a simulated model of rapid fluid infusion. Ten paired trials were conducted for each of three intravenous catheter gauges. Providers administered 500 mL of isotonic crystalloid through an intravenous catheter with both LifeFlow and a push-pull device. Administration time was compared between devices using paired t-tests. Participants' subjective physical demand, effort, pain, and fatigue using each device were recorded using 21-point visual analog scales and compared between devices using sign-rank tests. RESULTS Fluid administration time was significantly decreased with LifeFlow compared to the push-pull device with the 18-gauge catheter (2.5±0.8 vs 3.8±1.0 minutes; 95% CI of difference: 0.9, 1.8 minutes; P<0.001). Findings were similar for other catheter sizes. No improvements in subjective experience were noted with the LifeFlow device. Increased physical demand with the LifeFlow device was noted with 18 and 22 gauge catheters, and increased fatigue with the LifeFlow device was noted for all catheter sizes. CONCLUSION The LifeFlow device was faster than the push-pull syringe method in our simulated scenario. However, provider subjective experience was not improved with the LifeFlow device.

Abstract
BACKGROUND The Appalachian region is medically underserved and characterized by high morbidity and mortality. We investigated disparities among patients listed for liver transplantation (LT) in wait-list outcomes, according to residence in the Appalachian region. METHODS Data on adult patients listed for LT were obtained from the United Network for Organ Sharing for July 2013 to December 2015. Wait-list outcomes were compared using cause-specific hazard models by region of residence (Appalachian vs non-Appalachian) among patients listed at centers serving Appalachia. Posttransplant patient and graft survival were also compared. The study included 1835 LT candidates from Appalachia and 5200 from non-Appalachian regions, of whom 1016 patients experienced wait-list mortality or were delisted; 3505 received liver transplants. RESULTS In multivariable analyses, patients from Appalachia were less likely to receive LT (hazard ratio [HR] = 0.86; 95% confidence interval [CI]: 0.79-0.93; P < .001), but Appalachian residence was not associated with wait-list mortality or delisting (HR = 1.03; 95% CI: 0.89-1.18; P = .696). Among liver transplant recipients, patient and graft survival did not differ by Appalachian versus non-Appalachian residence. CONCLUSION Appalachian residence was associated with lower access to transplantation after listing for LT. This geographic disparity should be addressed in the current debate over reforming donor liver allocation and patient priority for LT.

Abstract
Introduction Epidural anesthesia is frequently used to provide postoperative analgesia following major surgical procedures. Secure fixation of the epidural catheter is necessary to prevent premature dislodgment and loss of epidural analgesia. Using an in vitro model, the current prospective study evaluates different types of dressings for securement of an epidural catheter by quantifying the force in Newtons (N) required for dislodgment using a digital force gage. Methods Four methods of epidural catheter securement were used on a simulator mannequin: 1) Suresite® Window Clear Dressing, 2) Op-Site Post-Op® Visible Dressing, 3) Steri-Strips® and Suresite Window Clear Dressing, and 4) Steri-Strips and Op-Site Post-Op Visible Dressing. Each method of securement was assessed 10 times to calculate the mean force required to dislodge the catheter. Mean force of dislodgment for each method was compared using parametric tests. Results The force (mean ± SD) required for catheter dislodgment for the four methods was 14.0±2.9, 2, 10.7±1.5, 8.6±2.3, and 9.6±2.2 N, respectively. The pairwise difference showed that the Suresite Window Clear Dressing was the best securement method when compared with other methods. Conclusion Our study demonstrates the advantage of the Suresite Window Clear Dressing in securing the epidural catheter. Future clinical trials are needed to validate these findings.

Abstract
Introduction Cerebral oxygenation can be monitored clinically by cerebral oximetry (regional oxygen saturation, rSO2) using near-infrared spectroscopy (NIRS). Changes in rSO2 have been shown to precede changes in pulse oximetry, providing an early detection of clinical deterioration. Cerebral oximetry values may be affected by various factors, including changes in ventilation. The aim of this study was to evaluate the changes in rSO2 during intraoperative changes in mechanical ventilation. Patients and methods Following the approval of the institutional review board (IRB), tissue and cerebral oxygenation were monitored intraoperatively using NIRS. Prior to anesthetic induction, the NIRS monitor was placed on the forehead and over the deltoid muscle to obtain baseline values. NIRS measurements were recorded each minute over a 5-min period during general anesthesia at four phases of ventilation: 1) normocarbia (35–40 mmHg) with a low fraction of inspired oxygen (FiO2) of 0.3; 2) hypocarbia (25–30 mmHg) and low FiO2 of 0.3; 3) hypocarbia and a high FiO2 of 0.6; and 4) normocarbia and a high FiO2. NIRS measurements during each phase were compared with sequential phases using paired t-tests. Results The study cohort included 30 adolescents. Baseline cerebral and tissue oxygenation were 81% ± 9% and 87% ± 5%, respectively. During phase 1, cerebral rSO2 was 83% ± 8%, which decreased to 79% ± 8% in phase 2 (hypocarbia and low FiO2). Cerebral oxygenation partially recovered during phase 3 (81% ± 9%) with the increase in FiO2 and then returned to baseline during phase 4 (83% ± 8%). Each sequential change (e.g., phase 1 to phase 2) in cerebral oxygenation was statistically significant (p < 0.01). Tissue oxygenation remained at 87%–88% throughout the study. Conclusion Cerebral oxygenation declined slightly during general anesthesia with the transition from normocarbia to hypocarbic conditions. The rSO2 decrease related to hypocarbia was easily reversed with a return to baseline values by the administration of supplemental oxygen (60% vs. 30%).

Abstract
Domino liver transplantation (DLT) utilizes the explanted liver of one liver transplant recipient as a donor graft in another patient. While there may be unique risks associated with DLT, it is unclear if DLT has less favorable long-term outcomes than deceased donor liver transplantation (DDLT). We used a propensity score matching approach to compare the outcomes of DLT recipients to DDLT recipients. The United Network for Organ Sharing (UNOS) registry was queried for patients undergoing DLT or DDLT in 2002-2016. Each DLT recipient was matched to a unique DDLT recipient to compare mortality and graft failure. There were 126 DLT and 62 835 DDLT recipients meeting inclusion criteria. After propensity score matching on recipient pre-transplant characteristics, 123 DLT cases were matched to DDLT controls from the same UNOS region. On stratified Cox proportional hazards regression, DLT incurred no increase in the hazard of mortality [hazard ratio (HR) = 1.4; 95% confidence interval (CI): 0.8, 2.7; P = 0.265] or graft failure (HR = 1.2; 95% CI: 0.7, 2.1; P = 0.556) compared to DDLT. Using a large national registry, a propensity-matched analysis found no increased risk of mortality or graft failure associated with DLT compared to DDLT.

Abstract
Based on animal data, concern has been expressed regarding the potential deleterious neurocognitive effects of general anesthesia during infancy and early life. Although there are no definitive data to prove this effect, the neonatal period has been suggested to be the most vulnerable period. While various inhaled and intravenous anesthetic agents have been implicated, dexmedetomidine and the opioids may be devoid of such effects. However, there are limited data regarding the combination of these agents during neonatal surgery and anesthesia. We present the use of these agents in combination with epidural anesthesia for postoperative analgesia in a 1-day-old neonate during thoracotomy and excision of a congental cystic adenomatoid malformation. Previous reports of the use of this unique combination of agents are reviewed and their role in this scenario discussed.

Abstract
BACKGROUND Existing risk adjustment models for solid organ transplantation omit socioeconomic status (SES). With limited data available on transplant candidates' SES, linkage of transplant outcomes data to geographic SES measures has been proposed. We investigate the utility of county SES for understanding differences in pediatric kidney transplantation (KTx) outcomes. METHODS We identified patients < 18 years of age receiving first-time KTx using United Network for Organ Sharing registry data in two eras: 2006-2010 and 2011-2015, corresponding to periods of county SES data collection. In each era, counties were ranked by 1-year rates of survival with intact graft, and by county SES score. We used Spearman correlation (ρ) to evaluate the association between county rankings on SES and transplant outcomes in each era and consistency between these measures across eras. We also evaluated the utility of county SES for improving prediction of individual KTx outcomes. RESULTS The analysis included 2972 children and 108 counties. County SES and transplant outcomes were not correlated in either 2006-2010 (ρ = 0.06; p = 0.525) or 2011-2015 (ρ = 0.162, p = 0.093). County SES rankings were strongly correlated between eras (ρ = 0.99, p < 0.001), whereas county rankings of transplant outcomes were not correlated between eras (ρ = 0.16, p = 0.097). Including county SES quintile in individual-level models of transplant outcomes did not improve model predictive utility. CONCLUSIONS Pediatric kidney transplant outcomes are unstable from period to period at the county level and are not correlated with county-level SES. Appropriate adjustment for SES disparities in transplant outcomes could require further collection of detailed individual SES data.

Abstract
BACKGROUND Health insurance coverage changes for many patients after liver transplantation, but the implications of this change on long-term outcomes are unclear. AIMS To assess post-transplant patient and graft survival according to change in insurance coverage within 1 year of transplantation. METHODS We queried the United Network for Organ Sharing for patients between ages 18-64 years undergoing liver transplantation in 2002-2016. Patients surviving > 1 year were categorized by insurance coverage at transplantation and the 1-year transplant anniversary. Multivariable Cox regression characterized the association between coverage pattern and long-term patient or graft survival. RESULTS Among 34,487 patients in the analysis, insurance coverage patterns included continuous private coverage (58%), continuous public coverage (29%), private to public transition (8%) and public to private transition (4%). In multivariable analysis of patient survival, continuous public insurance (HR 1.29, CI 1.22, 1.37, p < 0.001), private to public transition (HR 1.17, CI 1.07, 1.28, p < 0.001), and public to private transition (HR 1.14, CI 1.00, 1.29, p = 0.044), were associated with greater mortality hazard, compared to continuous private coverage. After disaggregating public coverage by source, mortality hazard was highest for patients transitioning from private insurance to Medicaid (HR vs. continuous private coverage = 1.32; 95% CI 1.14, 1.52; p < 0.001). Similar differences by insurance category were found for death-censored graft failure. CONCLUSION Post-transplant transition to public insurance coverage is associated with higher risk of adverse outcomes when compared to retaining private coverage.

Abstract
We investigated whether patterns of health insurance coverage were associated with 30-day all-cause acute care revisits after ambulatory tonsillectomy at a free-standing quaternary-care pediatric hospital. Insurance patterns were classified from past encounters as continuous private, continuous Medicaid, Medicaid-to-private change, or private-to-Medicaid change. Among 478/675 boys/girls (age 9 ± 4 years) selected for analysis, 148 (13%) had 30-day revisits, whereas 96 (8%) changed from Medicaid to private insurance, and 99 (9%) changed from private insurance to Medicaid. Revisits were most common in the private-to-Medicaid group, compared with continuous private coverage (19% vs 10%; 95% CI of difference: 1%-18%; P = .007). The private-to-Medicaid group was most likely to be overweight, have symptoms of sleep disordered breathing, and have more past clinical encounters. In multivariable analysis, the greater risk of acute care revisits among children with private-to-Medicaid change in coverage was attributable to greater comorbidity burden and past health care utilization.

Abstract
Sugammadex is a novel agent for the reversal of neuromuscular blockade. The speed and efficacy of reversal with sugammadex are significantly faster than acetylcholinesterase inhibitors, such as neostigmine. Sugammadex also has a limited adverse profile when compared with acetylcholinesterase inhibitors, specifically in regard to the incidence of bradycardia. This adverse effect may be particularly relevant in the setting of a heart transplant recipient with a denervated heart. The authors present a case of an 8-year-old child, status postcardiac transplantation, who required anesthetic care for laparoscopy and lysis of intra-abdominal adhesions. Sugammadex was used to reverse neuromuscular blockade and avoid the potential adverse effects of neostigmine. The unique mechanism of action of sugammadex is discussed, previous reports of its use in this unique patient population are reviewed, and its potential benefits compared to traditional acetylcholinesterase inhibitors are presented.

Abstract
Spinal anesthesia (SA) has been used relatively sparingly in the pediatric population, as it is typically reserved for patients in whom the perceived risk of general anesthesia is high due to comorbid conditions. Recently, concern has been expressed regarding the potential long-term neurocognitive effects of general anesthesia during the early stages of life. In view of this, our center has developed a program in which SA may be used as the sole agent for applicable surgical procedures. While this approach in children is commonly used for urologic or abdominal surgical procedures, there have been a limited number of reports of its use for orthopedic procedures in this population. We present the use of SA for 6 infants undergoing tendon Achilles lengthening, review the use of SA in orthopedic surgery, describe our protocols and dosing regimens, and discuss the potential adverse effects related to this technique.

Abstract
In severe cases of status asthmaticus, when conventional therapies fail, volatile anesthetic agents remain a therapeutic option. When delivered outside of the operating room setting, specialized delivery techniques are needed to ensure the safe and effective use of volatile anesthetic agents. We present a 16-year-old adolescent with status asthmaticus who required the therapeutic administration of the volatile anesthetic agent, sevoflurane, in the pediatric intensive care unit (PICU). Although initially effective in reducing bronchospasm, progressive hypercarbia developed due to defective functioning of the carbon dioxide absorber of the anesthesia machine. This failure occurred as the soda lime compartment filled with water accumulated from circuit humidification and continuous albuterol therapy. The role of volatile anesthetic agents in the treatment of status asthmaticus in the PICU is discussed, options for delivery outside of the operating room presented, and potential problems with delivery reviewed.

Abstract
BACKGROUND Studies have shown significant variation in the tracheobronchial angles in pediatric-aged patients. The current study revisits tracheobronchial angle measurements in children using accurate computed tomography-based 3-dimensional images to add clarity to the understanding of tracheobronchial angles. The primary objective of the current study was to measure the right and left bronchial angle take off from the trachea using 3-dimensional computed tomography-based images of the air column in the tracheobronchial tree. METHODS Computed tomography-based images of 45 children younger than 8 years were reviewed. The children were evaluated during spontaneous ventilation either during natural sleep or with sedation. The right and left bronchial angles were computed between the central axes of the respective main bronchi and a vertical line passing through the central axis of the longitudinal tracheal air column. The right and left bronchial angles were compared using paired t tests, and the age dependence of the right bronchial angle and left bronchial angle difference was evaluated using Pearson's correlation coefficient. RESULTS The study cohort included 18 males and 27 females with an average age of 49 ± 25 months. The right bronchial angle ranged from 23° to 56° (mean 42 ± 7°), whereas left bronchial angle varied between 25° and 68° (mean 43 ± 9°). The difference in means of 1 degree was not statistically significant (95% confidence interval of difference: -1°, 4°; P = .282). No association was found between left and right bronchial angle difference and patient age (r = -.019). CONCLUSION According to computed tomography-based 3-dimensional imaging, right and left bronchial angles are virtually identical in children up to 8 years of age, and the difference between right and left bronchial angles does not vary with age in this population.

Abstract
Purpose Few data exist on combining pediatric surgical procedures under a single general anesthetic encounter (general anesthesia). We compared perioperative outcomes of combining dental surgical procedures with tonsillectomy during one anesthetic vs separate encounters. Methods We classified elective tonsillectomy ± adenoidectomy and restorative dentistry as combined (group C) or separate (group S). Outcomes included anesthesia time, recovery duration, the need for overnight hospital stay, and postoperative complications. Results Patients aged 4±1 years underwent tonsillectomy and dental surgery in combination (n=7) or separately (n=27). No differences were noted in total anesthesia time (C: median: 150, interquartile range [IQR]: 99, 165 vs S: median: 109, IQR: 92, 132; 95% CI of difference in median: −58, +10 minutes; P=0.115) and total recovery time (C: median: 54, IQR: 40, 108 vs S: median: 72, IQR: 58, 109; 95% CI of difference in median: −16, +48 minutes; P=0.307). The need for overnight stay (C: 4 of 7, S: 20 of 27; P=0.394) did not differ between the groups. No postoperative complications were noted in either group. Conclusion These preliminary data support the potential feasibility of combining dental procedures with tonsillectomy during a single anesthetic encounter. Such care may not only reduce costs but also limit parental work absences and increase convenience for patient families. When compared with procedures performed separately, combined procedures did not result in increased morbidity or significant changes in postoperative outcomes.

Abstract
BACKGROUND The distance from the dura to spinal cord is not uniform at different vertebral levels. The dura to spinal cord distance may be a critical factor in avoiding the potential for neurological injury caused by needle trauma after a dural puncture. Typically, the greater the dura to spinal cord distance, the larger the potential safety margin. The objective of our study is to measure dura to spinal cord distance at two thoracic levels T6 -7 , T9 -10 , and one lumbar level L1 -2 using MRI images. METHODS Eighty-eight children under the age of 8 years old qualified for the study. The distance from dural side of ligamentum flavum to the posterior margin of the spinal cord was defined as dura to spinal cord distance. Sagittal T2 -weighted images of the thoracic and lumbar spine were used to measure the dura to spinal cord distance at the T6-7 , T9-10 , and L1-2 interspaces. Measurements were taken perpendicular to long axis of the vertebral body at each level. RESULTS The dura to spinal cord distance was 5.9 ± 1.6 mm at T6-7 (range: 1.4-9.9 mm), 5.0 ± 1.6 mm at T9-10 (1.2-8.1 mm), and 3.6 ± 1.2 mm at L1-2 (1.2-6.8 mm). There were no evident differences in dura to spinal cord distance by gender, age, height, or weight. CONCLUSION The present study reports that the largest dura to spinal cord distance is found at the T5-6 level, and the shortest dura to spinal cord distance at the L1-2 level. There appears to be substantially more room in the dorsal subarachnoid space at the thoracic level. The risk of spinal cord damage resulting from accidental epidural needle advancement may be greater in the lumbar region due to a more dorsal location of the spinal cord in the vertebral canal compared to the thoracic region.

Abstract
Avoidance of red blood cell (RBC) transfusions in patients awaiting heart transplantation (HTx) has been suggested to minimize the risk of allosensitization. Although recent studies have suggested that an immature immune system in younger HTx recipients may reduce risks associated with RBC transfusion, the role of age in moderating the influence of transfusion on HTx outcomes remains unclear. We used available data from a national transplant registry to explore whether the association between pre-transplant transfusions and outcomes of pediatric HTx varies by patient age. De-identified data were obtained from the United Network for Organ Sharing registry, including first-time recipients of isolated HTx performed at age 0-17 years in 1995-2015. The primary exposure was receiving blood transfusions within 2 weeks prior to HTx. Patient survival after HTx was evaluated using multivariable Cox proportional hazards, where age at transplant was interacted with exposure to pre-transplant transfusion. Age-specific hazard ratios (HRs) of pre-transplant transfusion were plotted across ages at transplant. There were 4883 patients meeting inclusion criteria, of whom 1258 died during follow-up (mean follow-up duration 6 ± 5 years). Patients receiving pre-transplant transfusions were distinguished by younger age, higher prevalence of prior cardiac surgery, greater likelihood of being in the intensive care unit, and greater use of left ventricular assist device bridge to transplant. In multivariable analysis, pre-transplant transfusions were associated with increased mortality hazard among infants < 1 year of age (HR = 1.46; 95% CI 1.23, 1.74; p < 0.001). For each additional year of age, the excess hazard associated with pre-transplant transfusions decreased by 3% (interaction HR = 0.97; 95% CI 0.98, 0.99; p = 0.003). By age 8, the association between pre-transplant transfusions and post-transplant mortality was no longer statistically significant (HR = 1.15; 95% CI 0.99, 1.32; p = 0.060). Pre-transplant transfusions were associated with increased mortality hazard only among younger children (age < 8 years) undergoing HTx. These data support the current practices of transfusion avoidance prior to HTx, particularly in younger patients.

Abstract
The preoperative evaluation is the first step in ensuring the safe conduct of anesthetic care in pediatric patients of all ages. Over time, this process has changed significantly from a time when patients were admitted to the hospital the night before surgery to a time when the majority of patients, including those scheduled for major surgical procedures, arrive the day of surgery. For most patients, the preoperative examiantion can be conducted over the phone by a trained nurse or on-line via a survey thereby eliminating the need for a separate visit merely for the preoperative evaluation. Regardless of where or how it occurs, the goals of the preoperative evaluation are to gain information regarding the patient's current status, comorbid conditions, and the intended procedure. This process allows the identification of patients who require additional preoperative testing or those patients who need to be seen by an anesthesiolgoist prior to the day of surgery. During the preopeative evalaution, decisions are made regarding further laboratory or investigative work-up that are required. The preoperative meeting provides an arena to develop the initial parent-physcian rapport, outline anesthetic risks, and discuss the intended anesthetic plan including options for postoperative analgesia. The process facilitates the care of patients during the perioperative period while limiting surgical cancellations resulting from patient-related issues. The following chapter reviews the essential components of the preoperative evaluation including the appropraite use of preoperative laboratory testing and other investigative procedures including radiologic imaging. Key components of the physical examinatino including the airway examination are reviewed.

Abstract
BACKGROUND There are limited data to guide the selection of the appropriate sized endobronchial tube for main stem intubation to provide one-lung ventilation in children. The relationship between the cricoid and the main bronchi (right and left) has been previously evaluated using two-dimensional computed tomography (CT) imaging and video-bronchoscopic images. The present study defines the three-dimensional, CT-derived volume-based relationships between the right main-stem bronchus (RMB), left main-stem bronchus (LMB), and the cricoid ring. METHODS The three-dimensional CT images of 35 children, less than 8 years of age, undergoing radiological evaluation unrelated to airway or mediastinal symptomatology were examined. The images of the airway column were evaluated at the level of the cricoid and main stem bronchi (right and left). Volumes were calculated and comparisons made between these levels. RESULTS There was no statistically significant difference based on gender for the cricoid and main stem bronchi volumes. A statistically significant difference was observed between the cricoid and left main stem bronchi volumes as well as between the right and left main stem bronchi. CONCLUSION The relationship (ratio) between the volumes of the cricoid and main stem bronchi remains constant by age. The cricoid dimensions can be used to predict the main stem bronchi dimensions.

Abstract
The population prevalence of pediatric chronic pain is not well characterized, in part because of a lack of nationally representative data. Previous research suggests that pediatric chronic pain prolongs inpatient stay and increases costs, but the population-level association between pediatric chronic pain and health care utilization is unclear. We use the 2016 National Survey of Children's Health to describe the prevalence of pediatric chronic pain, and compare health care utilization among children ages 0 to 17 years according to the presence of chronic pain. Using a sample of 43,712 children, we estimate the population prevalence of chronic pain to be 6%. In multivariable analysis, chronic pain was not associated with increased odds of primary care or mental health care use, but was associated with greater odds of using other specialty care (odds ratio [OR] = 2.01, 95% confidence interval [CI] = 1.62-2.47; P < .001), complementary and alternative medicine (OR = 2.32, 95% CI = 1.79-3.03; P < .001), and emergency care (OR = 1.62, 95% CI = 1.29-2.02; P < .001). In this population-based survey, children with chronic pain were more likely to use specialty care but not mental health care. The higher likelihood of emergency care use in this group raises the question of whether better management of pediatric chronic pain could reduce emergency department use. PERSPECTIVE Among children with chronic pain, we show high rates of use of emergency care but limited use of mental health care, which may suggest opportunities to increase multidisciplinary treatment of chronic pain.

Abstract
Background The use of complementary and alternative medicine (CAM) therapies has increased in children, especially in those with chronic health conditions. However, this increase may not translate into acceptance of CAM in the perioperative setting. We surveyed caregivers of patients undergoing surgery to determine their knowledge and acceptance of hypnotherapy, acupuncture, and music therapy as alternatives to standard medication in the perioperative period. Materials and methods An anonymous, 12-question survey was administered to caregivers of children undergoing procedures under general anesthesia. Caregivers reported their knowledge about hypnotherapy, music therapy, and acupuncture and interest in one of these methods during the perioperative period. CAM acceptance was defined as interest in one or more CAM methods. Results Data from 164 caregivers were analyzed. The majority of caregivers were 20-40 years of age (68%) and mothers of the patient (82%). Caregivers were most familiar with acupuncture (70%), followed by music therapy (60%) and hypnotherapy (38%). Overall CAM acceptance was 51%. The acceptance of specific CAM modalities was highest for music therapy (50%), followed by hypnotherapy (17%) and acupuncture (13%). In multivariable logistic regression, familiarity with music therapy was associated with greater odds of CAM acceptance (odds ratio=3.36; 95% CI: 1.46, 7.74; P=0.004). Conclusion Overall CAM acceptance among caregivers of children undergoing surgery was 51%, with music therapy being the most accepted CAM method. Familiarity with music therapy was the only factor that was independently associated with accepting CAM in the perioperative period. The low acceptance for acupuncture and hypnosis in the perioperative situation may be related to insufficient parental knowledge and information.

Abstract
PURPOSE MRI is a common modality for diagnostic imaging. In children, general anesthesia is often required to complete MRI examinations. Simulation training can reduce the need for anesthesia in some children. Reliable screening tools to select who could benefit from practice MRI sessions are lacking. This study evaluates the use of the modified Yale Preoperative Anxiety Scale (mYPAS) in effectively identifying patients who may benefit from simulation-based training. METHODS Children aged 5 and older who were originally scheduled for MRI with anesthesia in 2015 to 2016 were prospectively recruited for simulation-based training. The mYPAS assessment was performed by trained certified child life specialists before and after practice MRI sessions. The primary outcome was whether mYPAS could predict completing an MRI examination without anesthesia. RESULTS Eighty patients (43 boys and 37 girls, age 8.5 ± 3.0 years) were enrolled in the study. Eleven subjects (14%) required general anesthesia to complete the MRI examination despite participating in the simulation. In the overall cohort, mYPAS scores improved after simulation from 31 ± 11 to 27 ± 9 (95% confidence interval of difference, -6, -2; P < .001 by paired t test). Receiver operating characteristic curve analysis found that presimulation mYPAS had good utility for predicting anesthesia requirement for MRI completion (area under the curve = 0.81). A presimulation mYPAS score > 33 predicted need for anesthesia with 82% sensitivity and 78% specificity. CONCLUSIONS The mYPAS is a quick screening tool to identify pediatric patients who could benefit from simulation training by being able to complete an MRI examination without anesthesia.

Abstract
INTRODUCTION The aim of this review was to evaluate the current evidence regarding the use of dexmedetomidine as an adjuvant to local anesthetic agents (LAA) for caudal blockade anesthesia and analgesia in children. EVIDENCE ACQUISITION A literature search was performed of the Medline, Embase, and CINAHL databases using the keywords "dexmedetomidine" and "caudal". We included all studies that used caudal dexmedetomidine as an adjuvant to a LAA in children, excluding case reports, reviews, expert opinions, and animal studies. EVIDENCE SYNTHESIS Twenty-one publications met the inclusion criteria and included 1590 children. Fourteen compared the efficacy of adding dexmedetomidine to a LAA alone and seven compared dexmedetomidine to other adjuvants in combination with a LAA. The duration of postoperative analgesia was significantly longer in patients receiving a caudal epidural block with a LAA plus dexmedetomidine when compared to a LAA alone. Only one study demonstrated improved analgesia with a dose of dexmedetomidine ≥1 µg/kg. Dexmedetomidine provided longer postoperative analgesia than fentanyl and morphine, while the quality of postoperative analgesia was similar to dexamethasone or clonidine. Although higher sedation scores were associated with caudal dexmedetomidine in the majority of the trials, postoperative behavior scores were improved in these children. There were no reports of respiratory depression. Significant hemodynamic effects were uncommon, and occurred most commonly in patients receiving a higher dose of caudal dexmedetomidine (2 µg.kg-1). CONCLUSIONS There is sufficient evidence to recommend the addition of caudal dexmedetomidine to the LAA in patients undergoing lower extremity and infra-umbilical surgical procedures.

Abstract
One of the challenges during the perioperative care of patients with myotonic dystrophy is the reversal of neuromuscular blocking agents. Agents that inhibit acetylcholinesterase, such as neostigmine, may precipitate myotonia, and are therefore relatively contraindicated. Sugammadex is a novel pharmacologic agent, which encapsulates rocuronium or vecuronium, thereby reversing their effect. We report anecdotal experience with the use of sugammadex to reverse neuromuscular blockade in a patient with myotonic dystrophy. Concerns with the reversal of neuromuscular blockade in patients with myotonic dystrophy are presented, previous reports of the use of sugammadex in similar clinical scenarios are reviewed, and its advantages are discussed.

Abstract
Total anomalous pulmonary venous return (TAPVR) is a rare congenital cardiac defect, accounting for 1.5-3% of cases of congenital heart disease. With prenatal ultrasonography, the majority of these patients are diagnosed in utero with definitive surgery performed during the neonatal period. However, as prenatal screening may not be available in developing countries, patients may present in later infancy. We present successful surgical repair of a 6-month-old infant with TAPVR who presented for medical care at 5 months of age in Lima, Peru. The late presentation of such infants and the limited resources available for the treatment of elevated pulmonary vascular resistance may impact successful surgical correction of such defects. The perioperative care of such infants in developing countries is discussed and strategies for managing postoperative pulmonary hypertension is reviewed.

Abstract
Background Curcumin is a polyphenol extracted from the turmeric plant which may have anti-inflammatory properties. We hypothesized that curcumin pretreatment would result in a reduction in inflammatory markers in a large animal model of extracorporeal support. Methods A total of seven samples were obtained from three swine treated with curcumin and 16 samples were obtained from six swine in the control group (procedure terminated in two swine before last sample could be obtained). Results Samples for interleukin (IL)-8 and IL-1b had concentrations below the limit of detection at all points and were discarded from further analysis. IL-6, tumor necrosis factor (TNF)-α, and intercellular adhesion molecule (ICAM)-1 concentrations were lower in curcumin pretreated animals when compared to control animals. This decrease was statistically significant for TNF-α, and ICAM-1. Conclusions This project may provide information for the development of a translational study in humans as we noted that curcumin pretreatment in a large animal model of cardiopulmonary bypass (CPB) and extracorporeal support resulted in a decrease in TNF-α and ICAM-1 expression compared to control animals.

Abstract
Loss of airway control in children, if not resolved quickly, will lead to devastating consequences. Successful management of the pediatric difficult airway, both anticipated and unanticipated, is facilitated by preprocedure assessment and preparation. Accessibility of and continued hands-on training with modern airway instruments, familiarization with difficult airway guidelines, and collaboration with multidisciplinary airway teams can aid in the management of the difficult pediatric airway. This review outlines the importance of airway assessment and advanced airway equipment for children. It also discusses difficult airway management techniques and algorithms for the management and rescue of the pediatric difficult airway.

Abstract
Patients with Duchenne muscular dystrophy (DMD) often have systemic manifestations with comorbid involvement of the cardiac and respiratory systems that increase the risk of anesthetic and perioperative morbidity. These patients frequently develop progressive myocardial involvement with cardiomyopathy, depressed cardiac function, and arrhythmias. The latter may necessitate the placement of an automatic implantable cardioverter defibrillator (AICD) insertion. As a means of avoiding the need for general anesthesia and its inherent potential of morbidity, regional anesthesia may be used in specific cases. We present two cases of successful AICD insertion in patients with DMD using unilateral pectoralis and intercostal nerve blocks supplemented with intravenous sedation. Relevant anatomy for this regional anesthetic technique is reviewed and benefits of this anesthetic technique compared to general anesthesia are discussed.

Abstract
OBJECTIVES Neuromuscular blocking agents (NMBAs) are administered to facilitate endotracheal intubation and provide skeletal muscle relaxation in surgical procedures. Sugammadex (Bridion) recently received approval by the United States Food and Drug Administration for reversal of rocuronium and vecuronium-induced neuromuscular blockade thereby providing an alternative to acetylcholinesterase inhibitors such as neostigmine. This quality improvement analysis sought to investigate the clinical reasons and common clinical perceptions for choosing sugammadex over neostigmine to reverse NMBAs. METHODS One hundred cases were reviewed where sugammadex was used for neuromuscular blockade reversal in the operating room. Cases were identified from electronic medical record reports. Anesthesia providers responsible for administering sugammadex were interviewed to obtain rationales for sugammadex use in the perioperative setting. Responses were reviewed to identify distinct reasons for using sugammadex. Two independent raters ranked the reasons according to prevalence. The study was exempt from Institutional Review Board approval as a quality improvement (QI) project. RESULTS Forty-two anesthesia providers (15 Certified Registered Nurse Anesthetists, 5 anesthesiology trainees, and 22 attending anesthesiologists) were interviewed to identify reasons why sugammadex was administered intraoperatively in 100 surgical cases (69/31 male/female patients, age 9.4 ± 6.5 years). The author identified the top 19 common reasons respondents chose to use sugammadex for each case, and independent raters reviewed the response summaries for those 19 primary reasons sugammadex was used. The most common reasons for choosing sugammadex were: 1) beneficial pharmacokinetics of the agent; 2) sugammadex's perceived superior efficacy over neostigmine; and 3) concerns regarding adverse effects of neostigmine and/or the anticholinergic agent. CONCLUSIONS Sugammadex has recently been introduced for clinical use to reverse NMBAs at our institution. Primary reasons and perceptions for its use over neostigmine included a limited adverse effect profile, a greater sense of control and predictability of patients' response, and a limited incidence of residual neuromuscular blockade.

Postoperative bradycardia following adenotonsillectomy in children: Does intraoperative administration of dexmedetomidine play a role? Int J Pediatr Otorhinolaryngol 2018; 104:210-215.

Abstract
INTRODUCTION Dexmedetomidine is a novel pharmacologic agent that has become a frequently used adjunct during care of pediatric patients with obstructive sleep apnea (OSA) undergoing tonsillectomy. While generally safe and effective, dexmedetomidine is associated with adverse effects of hypotension and bradycardia from its central sympatholytic effects. Due to safety concerns, our institution routinely admits patients with OSA for overnight cardiorespiratory monitoring following tonsillectomy. With such monitoring, we have anecdotally noted bradycardia in our patients and sought to investigate whether this was related to the increased use of intra-operative dexmedetomidine. METHODS We retrospectively reviewed records over an 11-month period to compare the incidence of postoperative bradycardia following hospital admission for tonsillectomy in patients who received dexmedetomidine versus those who did not. RESULTS The study cohort included 921 patients (371 received dexmedetomidine and 550 did not). Bradycardia was asymptomatically noted in 66 patients (7.2%). No patient required medical intervention for the bradycardia or developed clinical symptoms. There was no association of bradycardia with the intra-operative administration of dexmedetomidine (8.9% of patients who received dexmetomidine vs. 9.4% who did not). In multivariable analysis, bradycardia was more common among older patients, with the administration of topical or injected lidocaine, and with specific associated procedures (inferior turbinate coblation with out-fracture or direct laryngoscopy and bronchoscopy). CONCLUSION The increased incidence of asymptomatic bradycardia in our post-adenotonsillectomy patients seemed to relate more to increased utilization of postoperative cardiac telemetry, and did not appear associated with the use of dexmedetomidine use intra-operatively.

Abstract
Retropharyngeal abscesses in the pediatric population can cause severe respiratory distress. We report a rare case of significant airway obstruction in a 14-month-old patient requiring rapid, emergent tracheotomy after attempts at endotracheal intubation by an experienced airway surgeon were unsuccessful. The patient was diagnosed with streptococcal pharyngitis 9 days prior to presentation to our facility and was being treated with amoxicillin. Prompt diagnosis, communication, and appropriate multidisciplinary airway management can lead to successful outcomes even in these severe cases.

Abstract
Rasburicase, used in the prevention and treatment of tumor lysis syndrome (TLS), may cause hemolytic anemia and methemoglobinemia in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Although routine screening for G6PD deficiency has been recommended, given the turnaround time for test results and the urgency to treat TLS, such screening may not be feasible. We report a case of rasburicase-induced hemolytic anemia without methemoglobinemia in an adolescent with T-cell lymphoblastic lymphoma, TLS, and previously unrecognized G6PD deficiency. Previous reports of hemolytic anemia with rasburicase are reviewed, mechanisms discussed, and preventative strategies presented.
