Abstract
PURPOSE Batten disease or neuronal ceroid lipofuscinosis is the most prevalent neurodegenerative disorder of childhood. Previously reported perioperative complications in children with Batten disease have come mainly from single case reports. The primary aim of the current study was to investigate perioperative complications of patients with Batten disease in the largest cohort known to date. The secondary objective was to characterize the anesthetic management including the use of propofol and to assess its association with adverse events. METHOD We conducted a single center, retrospective descriptive study by querying the hospital's electronic medical record to identify patients with a diagnosis of Batten disease or ICD10 E75.4 who received anesthetic care from December 2014 to May 2019. RESULTS Thirty-five patients who underwent a total of 93 anesthetic encounters (range 1-11) were included in the analysis. A total of 29 adverse events were identified. Hypotension (N = 6, 6.5%) and bradycardia (N = 7, 7.5%) requiring treatment with medications were the most common adverse events. Other adverse events include oxygen desaturation (N = 4, 4.3%), seizures (N = 4, 4.3%), unanticipated hospital or ICU admission (N = 1, 1.1%), PACU phase 1 stay > 120 min (N = 2, 2.2%), hypothermia (N = 4, 4.3%), agitation (N = 1, 1.1%), and laryngospasm requiring treatment (N = 1, 1.1%). The number of preoperative anti-epileptic drugs (AEDs) had a positive correlation with the rate of perioperative adverse events. There was no statistical relationship of adverse events with intraoperative use of propofol (odds ratio 1.03, 95% CI 0.42-2.51). CONCLUSIONS The majority of these patients were managed without clinically significant perioperative complications. As previously reported, bradycardia, hypotension, and hypothermia were the most common adverse events. Routine avoidance of propofol in patients with Batten disease does not appear warranted.

Abstract
OBJECTIVES Postoperative respiratory adverse events (PRAEs) are known complications following adenotonsillectomy (AT). Clinical data at a single institution were reviewed to investigate the factors that may contribute to PRAEs in the postanesthesia care unit (PACU). The relationship between PRAEs in the PACU and escalation of care, defined as either an unplanned admission for outpatient surgery or unplanned pediatric intensive care unit (PICU) admission, was investigated. METHODS The perioperative records for all patients who underwent AT from 2016 to 2018 were reviewed. The surgical procedure was performed at both the main campus and the ambulatory surgery center in accordance with the institutional obstructive sleep apnea (OSA) guidelines. Patient characteristics and intraoperative medications were compared. Categorical variables were summarized as counts with percentages and compared using chi-square tests or Fisher's exact tests. Continuous variables were summarized as medians with interquartile ranges and compared using rank-sum tests. Multivariable logistic regression was performed to evaluate the association of intraoperative dosing with the occurrence of PRAEs. RESULTS The study cohort included 6110 patients. Ninety-three patients (2%) experienced PRAEs in the PACU. Of these 93 patients, 14 (15%) resulted in an escalation of care, nearly all of which were unplanned PICU admissions. PRAEs tended to occur in younger patients, non-Hispanic black patients, and those with a higher American Society of Anesthesiologists (ASA) status. CONCLUSIONS PRAEs are infrequent after AT at a tertiary institution with OSA guidelines in place. However, when PRAEs do occur, escalation of care may be required. Risk factors include age, ethnic background, and ASA physical status. LEVEL OF EVIDENCE III.

Abstract
Coagulation disturbances frequently occur in critically ill children. Four-factor prothrombin complex concentrate (4F-PCC) may have a potential role in managing these patients while avoiding concerns associated with fresh frozen plasma. However, data on this product in critically ill children is scarce. We retrospectively identified 24 critically ill pediatric patients who received 4F-PCC. The primary indication was to correct coagulopathy and control bleeding in the trauma or surgical setting. 4F-PCC effectively decreased the international normalized ratio level, a surrogate marker of hemostasis. Further study is warranted to identify efficacy, indications, optimal dosing, and adverse effects in the critically ill pediatric patients.

Abstract
Merosin-deficient congenital muscular dystrophy (MDCMD) is a progressive autosomal recessive disorder caused by the lack of expression of the α2-chain of laminin-211 glycoprotein. The defect results in skeletal muscle dysfunction with severe muscle weakness, hypotonia, proximal joint contractures, facial dysmorphism, and late or failed ambulation. Given the progressive neuromuscular involvement and the potential for neuromuscular scoliosis, patients frequently require anesthetic care during surgical procedures to correct orthopedic deformities. We present a 9-year-old girl with MDCMD who required anesthetic care during insertion of growing rods to correct neuromuscular scoliosis. Previous reports of anesthetic care for patients with MDCMD are presented and options for perioperative care are reviewed.

Abstract
For critically ill patients, point-of-care ultrasound (POCUS) has been rapidly adopted for use in emergency departments and critical care units for diagnostic purposes and to guide decision making. We present two unique clinical scenarios in the Pediatric Intensive Care Unit (PICU), one in which ultrasound was used as a diagnostic tool to identify pulmonary edema, and the other in which ultrasound was used to facilitate placement of a naso-duodenal tube for enteral feeding. The potential role of POCUS in the PICU is presented and its utility in these two unique clinical scenarios discussed. Although, many cases will still require further radiological tests, The success of POCUS lies in immediate diagnosis allowing at the spot therapeutic interventions without wasting precious time.Citation: Lyman R, Yamaguchi Y, Moharir A, Tobias JD.

Abstract
Introduction Aprepitant (Emend®) is a novel antiemetic agent that works through antagonism of neurokinin-1 (NK-1) receptors. To date, there are limited data regarding its use to prevent postoperative nausea and vomiting (PONV) in children. We retrospectively reviewed our initial 12-months experience with aprepitant after it was made available for perioperative use. Methods The anesthetic records of patients who received aprepitant were retrospectively reviewed and demographic, surgical, and medication data retrieved. Results The study cohort included 31 patients (15 male and 16 female) ranging in age from 4 to 27 years (15.7 ± 7.4 years) and in weight from 14.4 to 175.7 kilograms (59.3 ± 30.2 kgs). Most of the patients (30 of 31) received the capsule form and 1 received the liquid. The average dose of aprepitant administered was 0.9 ± 0.6 mg/kg; however, only one patient received dosing expressed as mg/kg, and the majority received a 40 mg capsule. All of the patients in the cohort had either a previous history of PONV or risk factors for PONV. PONV occurred in the PACU in 1 patient and during the first 24 postoperative hours in 3 additional patients. No adverse effects related to aprepitant use were noted. Conclusion Aprepitant was easily added to the preoperative regimen for pediatric patients who may require it. Our approach limited overuse and subsequent cost concerns. Future studies with a comparator group and a greater sample size are needed to demonstrate its efficacy, especially in comparison to time-honored agents such as ondansetron. No adverse effects were noted in our limited study cohort.

Abstract
The α2-adrenergic agonists (dexmedetomidine and clonidine) have been used in several different clinical scenarios in infants and children including sedation during mechanical ventilation, procedural sedation, supplementation of postoperative analgesia, prevention of emergence delirium, control of post-anesthesia shivering, treatment of withdrawal and prolonging of duration of neuraxial anesthesia. Hemodynamic effects including bradycardia and hypotension remain the predominant adverse effects reported with the α2-adrenergic agonists. We report hypothermia following intravenous sedation with dexmedetomidine and spinal anesthesia with a combination of bupivacaine and clonidine in a 2-month-old infant. The potential mechanisms involved are reviewed, the causal relationship between hypothermia and α2-adrenergic agonists is explored and interventions to avoid its development are presented.

Abstract
The transversus abdominis plane (TAP) block is a peripheral nerve block that was originally described in 2001. Considering the sensory distribution of the TAP block, which does not provide visceral anesthesia, it has been used primarily for postoperative analgesia. We present the use of a TAP block as the sole anesthetic for placement of a cutaneous vesicostomy in a 4-year-old child with multiple comorbid conditions. The basic principles of the TAP block are presented, and its previous use instead of general in various clinical scenarios is reviewed.

Abstract
BACKGROUND Spinal anesthesia (SA) is an established anesthetic technique for short outpatient pediatric urological cases. To avoid general anesthesia (GA) and expand regional anesthetics to longer and more complex pediatric surgeries, the authors began a program using a combined spinal/caudal catheter (SCC) technique. STUDY DESIGN The authors retrospectively reviewed the charts of all patients scheduled for surgery under SCC between December 2016 and April 2018 and recorded age, gender, diagnosis, procedure, conversion to GA/airway intervention, operative time, neuraxial and intravenous medications administered, complications, and outcomes. The SCC technique typically involved an initial intrathecal injection of 0.5% isobaric bupivacaine followed by placement of a caudal epidural catheter. At the discretion of the anesthesiologist, patients received 0.5 mg per kilogram of oral midazolam approximately 30 min prior to entering the operating room. One hour after the intrathecal injection, 3% chloroprocaine was administered via the caudal catheter to prolong the duration of surgical block. Intra-operative management included either continuous infusion or bolus dosing of dexmedetomidine, as needed, for patient comfort and to optimize surgical conditions. Prior to removal of caudal catheter in the post-anesthesia care unit, a supplemental bolus dose of local anesthesia was given through the catheter to provide prolonged post-operative analgesia. RESULTS Overall, 23 children underwent attempted SCC. SA was unsuccessful in three patients, and surgery was performed under GA. The remaining 20 children all had successful SCC placement. There were 11 girls and nine boys, with a mean age of 16.5 months (3.3-43.8). Surgeries performed under SCC included seven ureteral reimplantations, two ureterocele excisions/reimplantations, two megaureter repairs, four first-stage hypospadias repairs, one distal hypospadias repair, one second-stage hypospadias repair, two feminizing genitoplasties, and one open pyeloplasty. Average length of surgery was 109 min (range 63-172 min). Pre-operative midazolam was given in 13/20 (65%). All SCC patients were spontaneously breathing room air during the operation, and there were no airway interventions. Only one SCC patient received opioids intra-operatively. There were no intra-operative or perioperative complications. DISCUSSION This pilot study shows that the technique of SCC allows one to do more complex urologic surgery under regional anesthesia than what would be possible under pure SA alone. The main limitations of the study include the relatively small number of patients and the small median length of the operative procedures. As a proof of concept, however, this does show that complex genital surgery bladder level procedures such as ureteral reimplantation can be performed under regional anesthesia. CONCLUSION SCC allows for more complex surgeries to be performed exclusively under regional anesthesia, thus obviating the need for airway intervention, minimizing or eliminating the use of opioids, and thus avoiding known and potential risks associated with GA. The latter is of particular importance given current concerns regarding hypothetical neurocognitive effects of GA on children aged below 3 years.

Abstract
One of the many safety features of modern day anesthesia machines is the adjustable pressure limiting (APL) valve. This device regulates pressure within the anesthesia circuit during manual ventilation with the anesthesia bag. We report an unusual case where a crack in the APL valve allowed release of pressure from within the circuit resulting in ineffective bag-valve-mask ventilation of an infant. The appropriate steps to prevent such issues are reviewed, and an algorithm to quickly identify such intraoperative problems is presented.

Abstract
BACKGROUND Although preoperative anemia has been suggested to predict postsurgical morbidity and mortality among infants <1 year of age, the data were drawn from heterogeneous patient cohorts including severely ill infants undergoing complex, high-risk procedures. We aimed to determine whether untreated preoperative anemia was associated with increased risk of postoperative complications in infants <1 year of age who underwent pyloromyotomy, a common and relatively simple surgery. METHODS Infants <1 year of age undergoing pyloromyotomy were identified from the American College of Surgeons (ACS) National Surgical Quality Improvement Program-Pediatric database. Preoperative anemia was defined as a hematocrit ≤40% for infants 0-30 days of age and ≤30% for infants more than 30 days of age. Patients who received pre- or postoperative blood transfusions were excluded. RESULTS We identified 2948 patients who met our inclusion criteria, of whom 843 were anemic (29%). The overall rate of complications in this cohort was 6%. The most common postoperative complications were readmission (97 cases), surgical site infection (43), reoperation (39), prolonged hospital stay (24), urinary tract infection (3), 30-day mortality (3) and cardiac arrest (2). We found no differences in the incidence of complications in anemic versus nonanemic patients on bivariate analysis or multivariable logistic regression (adjusted odds ratio = 1.2; 95% confidence interval: 0.8-1.7; P = 0.319). CONCLUSIONS In relatively healthy infants undergoing pyloromyotomy, untreated preoperative anemia was not associated with postoperative compilations and should not be considered a significant risk factor.

Abstract
OBJECTIVE We prospectively evaluated intracuff pressure (IP) during one-lung ventilation (OLV) to characterize potential risk associated with overinflation of the cuff used for OLV. DESIGN Prospective observational study over a 2-year period, in infants and children undergoing thoracic surgery. The IPs of the tracheal and bronchial balloon were measured using a manometer and compared to a previously recommended threshold of 30 cmH2O. Data were compared by the device type used to achieve OLV. SETTING Freestanding tertiary-care pediatric hospital. PARTICIPANTS Patients ≤18 years of age undergoing thoracic procedures requiring OLV. INTERVENTIONS Measurement of IP. MEASUREMENTS AND MAIN RESULTS Thirty patients were enrolled (age 5 months-18 years) with a median weight of 28 kg. Median tracheal and bronchial IPs were 32 cmH2O (range: 11, 90) and 44 cmH2O (range: 10, 100), respectively. The tracheal and bronchial IPs exceeded 30 cmH2O in 13 of 20 patients (65%) and 21 of 30 patients (70%), respectively. CONCLUSIONS IP was high and in excess of recommended levels in most children undergoing OLV. Continuous monitoring of IP may be indicated during OLV to address the risks involved and ensure the prevention of complications related to high IP. TYPE OF STUDY Prospective comparative study. LEVEL OF EVIDENCE Level II.

Abstract
Purpose To compare invasive blood pressure (IBP) readings obtained from an arterial cannula with non-invasive blood pressure (NIBP) measurements from oscillometric cuffs on the upper and lower extremities of infants and children under general anesthesia. Patients and methods Patients under 10 years of age were enrolled in our study if they were to receive general anesthesia with planned placement of a radial arterial cannula. At 5 mins intervals, IBP was measured using a fluid-coupled pressure transducer and NIBP was measured with two oscillometers with appropriately sized cuffs placed on the upper arm and lower leg, for 10 readings per patient. Results The study enrolled 18 boys and 12 girls, ranging in age from 0 to 8 years. Across 300 data points, the absolute difference between the arm and invasive mean arterial pressure (MAP) measurements was 7±7 mmHg (range: 0–52 mmHg). The absolute difference between the leg and invasive MAP measurements was 8±8 mmHg (range: 0–52 mmHg). Although both non-invasive measurement sites demonstrated frequent deviation from invasive measurement, large deviations were more common when BP was measured at the leg (81 of 298 observations (27%) deviating by >10 mmHg) compared to the arm (60 of 300 observations (20%) deviating by >10 mmHg). Conclusion The frequency of clinically significant NIBP deviation in children under general anesthesia supports the importance of IBP monitoring when hemodynamic fluctuations are likely and would be particularly detrimental. NIBP measured at the lower leg is more likely to result in clinically significant deviation from invasively measured MAP than NIBP values obtained from an upper arm.

Abstract
Minimally invasive thoracic surgical techniques require effective lung separation using one-lung ventilation (OLV). Verification of lung isolation may be confirmed by auscultation, visual confirmation using fiberoptic bronchoscopy, or more recently, point-of-care ultrasound (POCUS). We describe anecdotal experience with POCUS to guide OLV during robotic-assisted thoracic surgery in a child. Techniques to confirm thoracic separation are reviewed and potential advantages of POCUS discussed.

Abstract
Although a laparoscopic approach may be preferred over open procedures for abdominal surgery, there are limited data on the effect of laparoscopic procedures on cerebral and renal oxygenation in neonates and young infants. Here, we evaluated the effect in neonates and infants. In this two-center prospective observational study, we evaluated changes in cerebral and renal regional oxygen saturation (rSO2) in infants during laparoscopic pyloromyotomy. Intraoperative hemodynamic and respiratory parameters and rSO2 were recorded. For the primary outcome, these parameters were compared at incision and at the end of pneumoperitoneum. The study cohort included 25 infants with a mean age of 40 ± 10 days and weight of 4.0 ± 0.6 kg. IAP at the beginning of laparoscopy was 10 ± 2 mmHg (range 7-15 mmHg). Although both cerebral and renal rSO2 decreased from incision compared to the end of laparoscopy, the decrease reached statistical significance only for cerebral rSO2 (81 ± 12 to 76 ± 16, p = 0.033). Similarly, the increase in fractional tissue oxygen extraction (FTOE) was only statistically significant for cerebral FTOE (0.18 ± 0.12 to 0.23 ± 0.16, p = 0.037). No change in hemodynamic or respiratory parameters was found. Although there was a decrease in cerebral rSO2 and increase in cerebral FTOE during pneumoperitoneum, the values did not decrease below those noted before anesthetic induction.

Abstract
Background and aims Caring for children with chronic pain incurs burdens of cost and time for families. We aimed to describe variation in caregiver burden among parents of adolescents with chronic pain who responded to a nationally-representative survey. Our secondary aim was to identify child and parent characteristics associated with increased caregiver burden. Methods We used de-identified, publicly-available data from the 2016 National Survey of Children's Health (NSCH), designed to be representative of non-institutionalized children in the United States. We analyzed data for households where an adolescent age 12-17 years old was reported by a parent to have chronic pain. Outcomes included the parent's time spent on the child's health needs, reduced labor force participation, and out-of-pocket medical costs. Results Data on 1,711 adolescents were analyzed. For adolescents with chronic pain, 15% of parents reported spending at least 1 h/week on their child's health care, 14% reported cutting back on paid work, and 36% reported spending ≥$500 on their child's health care in the past 12 months. Adolescents' general health status and extent of specialized health care needs predicted increased caregiver burden across the three measures. Conversely, no consistent differences in caregiver burden were noted according to demographic or socioeconomic characteristics. Conclusions Among adolescents with chronic pain identified on a nationally-representative survey, parents frequently reported reducing work participation and incurring out-of-pocket expenses in providing health care for their child. Caregiver burdens increased with indicators of greater medical complexity (e.g. presence of comorbidities, need for specialized health care) and poorer overall adolescent health status. Implications We add a national-level perspective to studies previously performed in clinical samples addressing caregiver burden in pediatric chronic pain. Initiatives to reduce the burden of caring for children with chronic pain, described in prior work, may be especially beneficial for families with adolescents whose chronic pain is accompanied by other health problems or requires coordination of care among multiple providers.

Abstract
Background Heart transplantation (HTx) is a treatment option for refractory end-stage heart failure. Severe illness requiring pre-transplant intensive care unit (ICU) stay may be a risk factor for diminished post-transplant survival, but this association is surprisingly inconsistent in recent studies. To clarify the significance of ICU stay as a risk factor for heart transplant outcomes, we aimed to define if patient age was a factor in which ICU stay was predictive of survival after HTx. Methods De-identified data were obtained on isolated first-time HTx performed during the years 2006 - 2015 from the UNOS Registry. Nine age groups were defined. The primary outcome was 1-year post-transplant mortality. Cox proportional hazard regression estimated unadjusted and adjusted hazard ratio (HR) associated with pre-transplant ICU stay in each age group. Results The analysis included 19,508 patients (9% deceased within 1 year). In the overall cohort, pre-transplant ICU stay was associated with increased hazard of 1-year mortality (HR = 1.3; 95% confidence interval (CI): 1.2 - 1.4; P < 0.001); but further univariate analysis showed a greater hazard of 1-year mortality associated with ICU stay in infants (HR = 2.2; 95% CI: 1.5 - 3.2; P < 0.001). However, the adjusted analysis found that adults ages 40 - 49 had the highest statistically significant hazard of 1-year mortality (HR = 1.5; 95% CI: 1.1 - 2.1; P = 0.011). Conclusions Our study established age variation in the association between ICU stay and survival after HTx, with this association being strongest among adults, 40 to 49 years of age, undergoing HTx. Previous data suggesting decreased survival in infants may be related to the increased use of extracorporeal membrane oxygenation as a mechanical cardiac assist rather than ventricular assist devices.

Abstract
Objective: Overnight admission may be necessary following adenotonsillectomy (T&A) in pediatric patients. This practice may reduce unplanned revisits following hospital discharge. Study design: Retrospective cohort study. Subjects: Children from the PHIS database. Methods: T&A performed in children during the years 2007–2015 were identified in the Pediatric Health Information System. The primary outcome was 7-day, all-cause readmission or emergency department (ED) revisit. Secondary analysis examined specific revisit types and 30-day revisits. The primary exposure was each institution’s annual rate of overnight stay after T&A. Results: The analysis included 411,876 procedures at 48 hospitals. Hospitals’ annual rates of overnight stay following T&A ranged from 3% to 100%, and 7-day revisit rates varied from 0% to 15%. The percentage or rate of 7-day revisits did not differ based on the use of overnight stay following T&A. At hospitals with higher overnight admission rates after T&A, 7-day revisits were more likely to take the form of inpatient admission rather than an ED visit. Conclusions: The current study confirms that pediatric hospitals vary widely in inpatient admission practices following T&A. This variation is not associated with differences in revisit rates at 7 and 30 days related to any cause. Although no mortality was noted in the current study, caution is suggested when deciding on the disposition of patients with comorbid conditions as risks related to various patients, anesthetic, and surgical-related issues exist. Risk stratification with appropriate identification of patients requiring overnight stay may be the most important for preventing acute care revisits after T&A.

Abstract
New observations from novel imaging techniques regarding the anatomy, dimensions, and shape of the pediatric airway have emerged and provide insight for potential changes in the clinical management of the airway in infants and children. These new findings are challenging the historical concepts of a funnel-shaped upper airway with the cricoid ring as the narrowest dimension. Although these tenets have been accepted and used to guide clinical practice in airway management, there are limited clinical investigations in children to support the validity of these concepts. Imaging modalities such as magnetic resonance imaging, computed tomography (CT) scanning, multi-detector CT imaging, and videobronchoscopy suggest the need to revisit the historical view of the pediatric airway. This manuscript reviews the historical evolution of pediatric airway studies, summarizes important scientific observations from recent investigations relevant to our clinical understanding of pediatric airway anatomy, and discusses the importance of these findings for pediatric airway management.

Abstract
Residual neuromuscular blockade following the use of non-depolarizing neuromuscular blocking agents (NMBAs) can lead to postoperative respiratory complications, including oxygen desaturation, atelectasis, and pneumonia. Sugammadex rapidly reverses steroidal NMBAs by encapsulating them in a highly stable water-soluble complex. This NMBA-sugammadex complex then undergoes renal elimination. In patients with renal insufficiency or failure, concern has been expressed regarding the elimination of the NMBA-sugammadex complex. We present a 19-year-old patient with renal failure who received sugammadex for reversal of neuromuscular blockade. The use of sugammadex in patients with renal dysfunction is discussed and safety concerns are reviewed.

Abstract
BACKGROUND The American Academy of Pediatrics recommends palliative care for children at the diagnosis of serious illness. Yet few children who die receive specialty palliative care consultation, and when it is provided, palliative care consultation tends to occur after >75% of the time from diagnosis until death. Focusing on the timing of palliative consultation in relation to the date of diagnosis, we evaluated factors predicting earlier receipt of pediatric palliative care in a cohort of decedents. METHODS We retrospectively identified patients diagnosed with a life-limiting disease who died at our hospital in 2015-2017 after at least 1 inpatient palliative medicine consultation. Our primary outcome was time from palliative-qualifying diagnosis to earliest receipt of specialty palliative care. A survival analysis was used to describe factors associated with earlier receipt of palliative care. RESULTS The analysis included 180 patients (median age at diagnosis <1 month [interquartile range (IQR): 0-77]). The median time to first palliative consultation was 7 days after diagnosis (IQR: 2-63), compared with a median of 50 days between diagnosis and death (IQR: 7-210). On the multivariable analysis, palliative consultation occurred earlier for patients who had cardiovascular diagnoses, had private insurance, and were of African American race. CONCLUSIONS In a cohort of decedents at our institution, palliative consultation occurred much earlier than has been previously reported. We also identify factors associated with delayed receipt of palliative care among children who are dying that reveal further opportunities to improve access to specialty palliative care.

Abstract
BACKGROUND Optimizing transplant candidates' priority for donor organs depends on the accurate assessment of post-transplant outcomes. Due to the complexity of transplantation and the wide range of possible serious complications, recipient outcomes are difficult to predict accurately using conventional multivariable regression. Therefore, we evaluated the utility of 3 ML algorithms for predicting mortality after pediatric HTx. METHODS We identified patients <18 years of age receiving HTx in 2006-2015 in the UNOS Registry database. Mortality within 1, 3, or 5 years was predicted using classification and regression trees, RFs, and ANN. Each model was trained using cross-validation, then validated in a separate testing set. Model performance was primarily evaluated by the area under the receiver operating characteristic (AUC) curve. RESULTS The training set included 2802 patients, whereas 700 were included in the testing set. RF achieved the best fit to the training data with AUCs of 0.74, 0.68, and 0.64 for 1-, 3-, and 5-year mortality, respectively, and performed best in the testing data, with AUCs of 0.72, 0.61, and 0.60, respectively. Nevertheless, sensitivity was poor across models (training: 0.22-0.58; testing: 0.07-0.49). DISCUSSION ML algorithms demonstrated fair predictive utility in both training and testing data, but the sensitivity of these algorithms was generally poor. With the registry missing data on many determinants of long-term survival, the ability of ML methods to predict mortality after pediatric HTx may be fundamentally limited.

Abstract
Background:There continues to be focus on the value of regional and neuraxial anesthetic techniques when combined with general anesthesia to improve postoperative analgesia. The reported advantages include decreased postoperative opioid requirements, decreased medication-related adverse effects, decreased hospital length of stay, and increased patient satisfaction. Orthopedic procedures of the hip may be amenable to such techniques as there is significant postoperative pain with the requirement for hospital admission and the administration of parenteral opioids. Given the surgical site, various regional anesthetic techniques may be used to provide analgesia including caudal epidural anesthesia (CEA) or lumbar plexus blockade (LPB). Purpose: The objective of this study was to assess the effectiveness of LPB versus CEA as an analgesic thechnique for patients undergoing elective hip surgery from the opioid consumption and pain scores perspective. Patients and methods: The current study retrospectively reviews our experience with CEA and LPB for postoperative analgesia after hip surgery in the pediatric population. Regional anesthesia technique was reviewed as well as opioid requirements and pain scores. Results: The study cohort included 61 patients, 29 who received an LPB and 32 who received CEA. No difference was noted in the demographics between the two groups. Intraoperative opioid use was 0.7 (IQR: 0.5, 1.1) mg/kg of oral morphine equivalents (MEs) in the LPB group compared to 0.6 (IQR: 0.5, 0.9) in the CEA group (p=0.479). Postoperative opioid use over the first 48 hrs was 4 (IQR: 1, 6) mg/kg of oral ME in the LPB group, compared to 2 (interquartile range [IQR]: 1, 3) in the CEA group (p=0.103). Over the first 24 hrs after surgery, the median pain score in the LPB group was 5 (IQR: 1–6), compared to 3 (IQR: 0, 5) in the CEA group (p=0.014).Conclusion: These retrospective data suggest a modest postoperative benefit of CEA when compared to LPB following hip surgery in the pediatric population. Postoperative pain scores were lower in patients receiving CEA; however, no difference in the intraoperative or postoperative opioid requirements was noted between the two groups.

Abstract
Regional anesthetic blocks, especially in-dwelling catheters, are infrequently used in neonates and infants. The following report describes a neonate with a gangrenous right upper extremity requiring multiple painful debridements over several weeks. A brachial plexus catheter was placed using ultrasound guidance, and a continuous infusion of a local anesthetic was used to provide postoperative pain control. After the initial procedures, bolus doses of a local anesthetic agent provided surgical anesthesia for dressing changes, thus obviating the need for multiple general anesthetics. This case demonstrates the potential efficacy of regional techniques to both treat pain and limit anesthetic exposures in neonates.

Abstract
Objective Accurate assessment of risk factors such as congenital heart disease (CHD) can aid in risk stratification of children presenting for surgery. Risk stratification is especially important in tonsillectomy ± adenoidectomy (T/A), a common pediatric procedure that is usually performed electively, but that has a high rate of adverse events. In this study, we examined the association of CHD with revisits after T/A. Methods We identified children who underwent T/A at hospitals and hospital‐owned facilities during 2010 to 2014 using the State Inpatient Databases and State Ambulatory Surgery and Services Databases of Florida, Georgia, Iowa, New York, and Utah. We evaluated the association between CHD severity and the occurrence of an unplanned hospital readmission or ED visit within 30 days following discharge using multivariable logistic regression. Results The analysis included 244,598 patients, of whom 858 had minor or major CHD. In multivariable analysis, CHD was not associated with an increased risk of 30‐day revisits (minor OR = 1.1; 95% CI: 0.8, 1.5; P = .65; major OR = 1.2; 95% CI: 0.9, 1.6; P = .34). Other comorbidities, including chromosomal anomalies (OR = 1.4; 95% CI: 1.2, 1.6; P < .001), congenital airway anomalies (OR = 1.3; 95% CI: 1.03, 1.7; P = .03), and neuromuscular impairment (OR = 1.4; 95% CI: 1.2, 1.7; P < .001) predicted an increased likelihood of revisits. Conclusion Neither minor nor major CHD was independently associated with an increased risk of 30‐day revisits among children undergoing T/A. Other characteristics, particularly non‐cardiac comorbidities, socioeconomic status, and geographic region may be of greater utility for predicting revisit risk following pediatric T/A.

Abstract
Background: The impact of specialty pediatric palliative care (PPC) on intensive care unit (ICU) length of stay for children is unclear. Objective: To estimate the impact of PPC consultation by analyzing ICU stay as a dynamic outcome over the course of hospitalization. Patients and Methods: Retrospective cohort study of children hospitalized with diagnoses suggested as referral triggers for PPC at a large academic children's hospital. We assessed ICU stay according to PPC consultation and, using a patient-day analysis, applied multivariable mixed effects logistic regression to predict the odds of being in the ICU on a given day. Results: The analytic sample included 777 admissions (11,954 hospital days), of which 100 admissions (13%) included PPC consultation. Principal patient demographics were age 8 ± 6 years, 55% male sex, 71% white race, and 52% commercial insurance. Cardiac diagnoses were most frequent (29%) followed by gastrointestinal (22%) and malignant (20%) conditions. Although total ICU stay was longer for admissions, including PPC consultation (compared to admissions where PPC was not consulted), the odds of being in the ICU on a given day were reduced by 79% after PPC consultation (odds ratio [OR] = 0.21; 95% confidence interval [CI]: 0.13-0.34; p < 0.001) for children with cancer and 85% (OR = 0.15; 95% CI: 0.08-0.26; p < 0.001) for children with nononcologic conditions. Conclusions: Among children hospitalized with a diagnosis deemed eligible for specialty PPC, the likelihood of being in the ICU on a given day was strongly reduced after PPC consultation, supporting the value of PPC.

Abstract
Pentalogy of Cantrell is a rare syndrome consisting of midline abnormalities involving the heart, sternum, abdominal wall, and the anterior and pericardial diaphragm. This combination of defects places patients at particular perioperative risk and requires individualized management during anesthetic care. The following report documents the management of a patient with pentalogy of Cantrell, whose condition was further complicated by severe midline craniofacial abnormalities, including large anterior encephalocele, deficient mandible, tethered tongue, and cleft palate. The case offers insight into the complexity of care in this unique patient population.

Abstract
OBJECTIVES/HYPOTHESIS Oxymetazoline is an α-adrenergic agonist that is commonly used as a topical hemostatic agent in the operating room during ear, nose, and throat surgery. There are limited data on oxymetazoline pharmacokinetics in children who undergo general anesthesia. We assessed the hemodynamic effects and systemic absorption of topically applied oxymetazoline in children undergoing various nasal procedures. STUDY DESIGN Prospective trial. METHODS Children ages 2 to 17 years undergoing functional endoscopic sinus surgery, turbinate resection, or adenoidectomy were enrolled. The surgeon placed oxymetazoline-soaked pledgets (1.5 mL of 0.05% solution) according to our usual clinical practice. Blood samples for oxymetazoline assay were drawn at 5, 10, 20, 45, 90, and 150 minutes, and hemodynamic data were recorded at 5-minute intervals. Data analysis included mixed-effects regression and population pharmacokinetic/pharmacodynamic modeling. RESULTS The analysis included 27 patients, age 7 ± 4 years, who received between 2 and 12 pledgets (3-18 mL) of oxymetazoline. Relative bioavailability compared to the spray formulation was 2.3 (95% confidence interval [CI]: 1.6-3.2), with slow absorption from the mucosal surface (absorption half-life 64 minutes; 95% CI: 44-90). Mean arterial pressure did not increase with oxymetazoline instillation at the observed oxymetazoline serum concentrations (0.04-7.6 μg/L). CONCLUSIONS Despite concerns regarding oxymetazoline administration to mucosal membranes, we found that hemodynamic changes were clinically negligible with our usual clinical use of pledgets soaked in oxymetazoline. Compared to data on oxymetazoline in spray formulation, bioavailability was increased twofold with pledgets, but systemic absorption was very slow, contributing to low serum concentrations and limited hemodynamic effects.

Abstract
INTRODUCTION Chronic opioid use is common after organ transplantation, and has been associated with poor outcomes in transplantation of abdominal organs. However, little is known about possible influences of chronic opioid use on outcomes of lung transplantation (LTx). OBJECTIVES We assessed whether long-term chronic opioid use influenced clinical outcomes among LTx recipients at our program. METHODS We retrospectively evaluated chronic opioid use among bilateral LTx recipients ages 12 and older followed at our institution 1-5 years post-transplant. Chronic opioid use was defined as ≥3 months of consecutive prescribed use. Outcomes included survival, hospitalization, emergency department and urgent care visits, forced expiratory volume in one second (FEV1), and allograft rejection. RESULTS Twenty-one patients ages 15-50 years met inclusion criteria. On multivariable analysis, initiation of chronic opioid use was followed by increased mortality hazard (hazard ratio=7.1; 95% confidence interval [CI]: 1.1, 45.0, P = 0.037) and decreased FEV1 (-16%; 95% CI: -24%, -7%; P < 0.001), although no differences were observed in risk of acute care visits, inpatient admission, or chronic rejection. CONCLUSION This analysis presents the first evidence that late-onset chronic opioid use may be associated with decreased lung function and increased mortality after LTx. Therefore, evaluation of chronic opioid use should be included in the routine monitoring of transplant recipients, to better define the impact of this risk factor on LTx outcomes.

Abstract
Acute flaccid myelitis (AFM) is a neurological disorder that affects the anterior horn of the spinal cord, resulting in progressive weakness, loss of motor function, hypotonia and hyporeflexia. Given the progressive and frequently long-term neurological involvement of AFM, patients may require anesthetic care during radiological imaging or other surgical procedures, such as a tracheostomy or the placement of a gastrostomy tube. We present a 4-year-old girl with AFM who required anesthetic care during a tracheostomy. The end-organ involvement of the disease is discussed, pathogenesis and treatment options are reviewed and anesthetic implications are presented.

Abstract
INTRODUCTION Children and adolescents identifying as lesbian, gay, bisexual, transgender, or queer/questioning (LGBTQ) may feel reluctant to seek medical care due to stigma and the possibility of negative interactions with health care providers. Due to the short duration of the perioperative period, the interaction in this setting is limited and providers may not have the time to develop a rapport with the patient. It is imperative that staff are trained to address the patient and family in a culturally competent manner. METHODS We undertook surveys before and after a 2 part educational series among the pediatric perioperative staff to understand the impact of providing education and cultural competency training regarding caring for patients who identify as LGBTQ. Providers self-reported their knowledge and comfort on a 1-5 point scale (5 being most knowledgeable or comfortable) in 6 domains of caring for LGBTQ patients. Objective knowledge of LGBTQ issues was assessed using 7 questions based on lecture material. On objective assessment, knowledge of LGBTQ issues improved after cultural competency training. RESULTS The analysis included 90 responses. Before training, median ratings of knowledge and comfort were 3 or 4 out of a maximum of 5 for each domain. The pre-training median score on the 7-item test of LGBTQ cultural competency was 5 (IQR: 4, 6). After training, knowledge and comfort self-ratings did not improve, but the score on the objective knowledge test increased to a median of 6 (IQR: 4, 7; p=0.011) of 7 possible points. DISCUSSION Anesthesia providers participating in LGBTQ cultural competency training self-reported high levels of knowledge and comfort with providing care to LGBTQ patients even before formal training was provided. On objective assessment, knowledge of LGBTQ issues improved after cultural competency training.

Abstract
BACKGROUND Intravenous acetaminophen is commonly administered as an adjunctive to opioids during major surgical procedures, but neither the correct pharmacokinetic size descriptor nor the dose is certain in severely obese adolescents undergoing bariatric surgery. METHODS Adolescents, 14-20 years of age, with a body mass index (BMI) ≥95th percentile for age and sex or BMI ≥40 kg·m-2 , presenting for laparoscopic or robotic assisted or vertical sleeve gastrectomy were administered intravenous acetaminophen (1000 mg) following completion of the surgical procedure. Venous blood was drawn for acetaminophen assay at eight time points, starting 15 minutes after completion of the infusion and up to 12 hours afterward. Time-concentration data profiles were analyzed using nonlinear mixed effects models. Parameter estimates were scaled to a 70-kg person using allometry. Normal fat mass was used to assess the impact of obesity on pharmacokinetic parameters. RESULTS The study cohort comprised 11 female patients, age 17 SD 2 years with a weight of 125 SD 19 kg and a mean BMI of 46 SD 5 kg·m-2 . The plasma acetaminophen serum concentration was 17 (SD 4) μg·mL-1 at 10-20 minutes after completion of the infusion and 5 (SD 6) μg·mL-1 at 80-100 minutes. A two-compartment model, used to investigate pharmacokinetics, estimated clearance 10.6 (CV 72%) L·h·70 kg-1 , intercompartment clearance 37.3 (CV 63%) L·h·70 kg-1 , central volume of distribution 20.4 (CV 46%) L·70 kg-1 , and peripheral volume of distribution 16.8 (CV 42%) L·70 kg-1 . Clearance was best described using total body weight. Normal fat mass with a parameter that accounts for fat mass contribution (Ffat) of 0.88 best described volumes. CONCLUSION Current recommendations of acetaminophen to a maximum dose of 1000 mg resulted in serum concentrations below detection limits in all patients within 2 hours after administration. Dose is better predicted using total body mass with allometric scaling.

Severe outcomes of pediatric perioperative adverse events occurring in operating rooms compared to off-site anesthetizing locations in the Wake Up Safe Database. Paediatr Anaesth 2019; 29:38-43.

Abstract
BACKGROUND Anesthesia services are frequently provided outside of the traditional operating room environment for children. It is unclear if adverse events which occur in off-site anesthetizing locations result in more severe outcomes compared to events in traditional operating rooms. AIM We used a multi-institutional registry of pediatric patients to compare outcomes of perioperative adverse events between location types. METHODS De-identified data from 24 pediatric tertiary care hospitals participating in the Wake Up Safe registry during 2010-2015 were analyzed. Peri-procedural adverse events occurring in operating rooms or off-site locations were included. The primary outcome was whether the adverse event was severe, defined as requiring escalation of care or resulting in temporary or significant harm. Multivariable logistic regression was used to compare location type (operating room vs. off-site) and the likelihood of a severe outcome among reported events. RESULTS There were 1594 adverse events, of which 362 were associated with off-site anesthetizing locations. In multivariable logistic regression, off-site location was associated with greater odds of severe adverse event outcome (adjusted odds ratio, 1.31; 95% confidence interval: 1.01, 1.69; P = 0.044). Comparing adverse events in cardiac catheterization suites to events in operating rooms confirmed higher odds of severe outcome in the former group (adjusted odds ratio = 1.48; 95% confidence interval: 1.05, 2.08; P = 0.025), while this difference was not found for other off-site locations. CONCLUSION Multivariable analysis of a large registry revealed a greater likelihood of severe outcome for adverse events occurring in cardiac catheterization suites (but not other out of the OR sites), compared to adverse events occurring in the operating room. Additional prospective studies are needed which better control for patient and environmental characteristics and their effect on severe outcomes after anesthesia.

Abstract
Background The incidence of obstructive sleep apnea (OSA) and sleep-disordered breathing (SDB) in children exceeds the availability of polysomnography (PSG) to definitively diagnose OSA and identify children at higher risk of perioperative complications. As sleep deficits are associated with slower reaction times (RTs), measuring RT may be a cost-effective approach to objectively identify SDB symptoms. Aim The aim of this study is to compare RT on a standard 10-minute psychomotor vigilance test (PVT) based on children’s history of OSA/SDB. Methods Children, 6–11 years of age, were enrolled from two different clinical groups. The SDB group included children undergoing adenotonsillectomy with a clinical history of SDB, OSA, or snoring. The control group included children with no history of SDB, OSA, or snoring who were scheduled for surgery other than adenotonsillectomy. RT was measured via 10-minute PVT (Ambulatory Monitoring Inc., Ardsley, NY, USA). Median RT was calculated for each patient based on all responses to stimuli during the PVT assessment and was compared to published age-sex-specific norms. The proportion of children exceeding RT norms was compared between study groups. Results The study included 72 patients (36/36 male/female, median age 7 years), 46 with SDB and 26 without SDB. There was no difference in the RT between the two groups. Fifty-four percent of patients with SDB exceeded norms for median RT vs 42% of control patients (95% CI of difference: – 12, 36; P=0.326). Conclusion Approximately half of the patients in both groups exceeded published norms for median RT on PVT. Despite its convenience, measurement of RT did not distinguish between patients with probable SDB/OSA for preoperative risk stratification.

Abstract
Pediatric transplant recipients experience barriers to social functioning, including participation in school and work, but our understanding of barriers to these activities is limited by insufficient data collection and standardization. Existing studies rely on cross-sectional surveys of transplant survivors that are subject to survivorship and nonresponse bias, or analyses of large registry data that lack detail on educational progress and work participation. We report our experience using the electronic medical record to retrospectively review work and educational attainment in this population, and identify specific barriers that were encountered and how they were addressed by the patient and care team. We reviewed current literature on post-transplant survey participation and compared questionnaires to our current documentation practice for tracking education and employment progress in the transplant recipient population. Based on this review, we discuss the possibility, barriers, and implications of conducting a standardized assessment to track social participation outcomes of transplantation.

Abstract
BACKGROUND Cardiac risk factors pose challenges in pediatric posterior spinal fusion (PSF). Differences in risk according to etiology of cardiac disease are unclear. We investigated outcomes of PSF according to presence of congenital heart defect compared to cardiomyopathy. METHODS Elective PSF for idiopathic scoliosis in patients aged 0-18 y was identified in the 2012-2015 National Surgical Quality Improvement Program-Pediatric. Cardiac risk factors were classified as: no cardiac risk factors or minor cardiac risk factors without congenital heart defect; minor cardiac risk factors because of congenital heart defect; major cardiac risk factors because of congenital heart defect; major cardiac risk factors because of cardiomyopathy. Multivariable logistic regression compared surgical site infection, wound dehiscence, hospital length of stay ≥30 d, and unplanned readmission across these categories. RESULTS The analysis included 5395 girls and 1691 boys, aged 14 ± 2 y. Among these, 140 patients had minor cardiac risk factors because of congenital heart defect, 144 had major cardiac risk factors because of congenital heart defect, and 20 had major cardiac risk factors because of cardiomyopathy. Rates of any complication were significantly higher among patients with cardiomyopathy (40%) compared to patients with major cardiac risk factors because of congenital heart defect (10%), minor cardiac risk factors because of congenital heart defect, or other minor or no cardiac risk factors (5%; chi-square P < 0.001). In multivariable analysis of 6829 patients, cardiomyopathy predicted greater odds of unplanned readmission compared to no or minor cardiac risk factors (OR = 5.9; 95% CI: 1.8, 19.7; P = 0.004) and compared to major cardiac risk factors because of congenital heart defect (OR = 4.5; 95% CI: 1.1, 17.6; P = 0.032). CONCLUSIONS Cardiomyopathy is a rare but significant risk factor for complications after pediatric PSF, whereas congenital heart defects did not independently contribute to risk of complications after this procedure.

Abstract
BACKGROUND Preoperative factors have been correlated with pre-incision hypotension (PIH) in children undergoing surgery, suggesting that PIH can be predicted through preoperative screening. We studied blood pressure (BP) changes in the 12 min following the induction of anesthesia to study the incidence of post-induction hypotension and to assess the feasibility of predicting PIH in low-risk children without preoperative hypotension or comorbid features. METHODS We retrospectively evaluated 200 patients ranging in age from 2 to 8 years with American Society of Anesthesiologists' (ASA) physical status I or II, undergoing non-cardiac surgery. Patients were excluded if they had preoperative (baseline) hypotension (systolic blood pressure (SBP) < 5th percentile for age). BP and heart rate (HR) were recorded at 3 min intervals for 12 min after the induction of anesthesia. Pre-incision hypotension (PIH) was initially defined as SBP < 5th percentile for age: (1) at any timepoint within 12 min of induction; (2) for the median SBP obtained during the 12 min study period; or (3) at 2 or more timepoints including the final point at 12 min after the induction of anesthesia (sustained hypotension). In addition, we examined PIH defined as > 20% decrease in SBP from baseline: (4) at any timepoint within 12 min of the induction of anesthesia; (5) for the median SBP obtained during the 12 min study period; or (6) at two or more timepoints including the final point at 12 min after the induction of anesthesia. Agreement among the six definitions was analyzed, in addition to the effects of age, gender, type of anesthetic induction, use of premedication, preoperative BP, preoperative HR, and body mass index on the incidence of PIH according to each definition. RESULTS Five patients were excluded due to baseline hypotension and six were excluded for missing data. In the remaining cohort, estimated PIH prevalence ranged from 4% [definition (Stewart et al., in Paediatr Anaesth 26:844-851, 2016), sustained PIH according to SBP percentile-for-age] to 57% [definition (Task Force on Blood Pressure Control in Children, in Pediatrics 79:1-25, 1987), at least one timepoint where SBP was > 20% lower than baseline]. Pairwise agreement among the six definitions ranged from 49 to 91% agreement. No sequelae of PIH were noted during subsequent anesthetic or postoperative care. On multivariable analysis, no covariates were consistently associated with PIH risk across all six definitions of PIH. CONCLUSION The present study describes the incidence and prediction of PIH in a cohort of relatively healthy children. In this setting, accurate prediction of PIH appears to be hampered by lack of agreement between definitions of PIH. Overall, there was a low PIH incidence when the threshold of SBP < 5th percentile for age was used. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND Due to the cost and inconvenience of polysomnography (PSG), wristworn accelerometers have been explored as an alternative method to measure sleep efficacy in children with obstructive sleep apnea (OSA) or sleep-disordered breathing (SDB). We compared the measurement of sleep quality with the Fitbit® Charge compared to PSG in children presenting for sleep studies. METHODS Children ages 3 to 18 years, presenting for PSG with persistent SDB symptoms were enrolled. During PSG, the Fitbit® Charge was placed on the wrist and timesynchronized with sleep laboratory devices, which were worn while a single-night PSG was performed. Bias and concordance in measurements of total sleep time (TST), total wake time (TWT), and number of awakenings were assessed using paired t-tests, sign-rank tests, and Lin's concordance coefficient. RESULTS The study cohort included 22 patients (9 boys and 13 girls; 9 ± 3 years). TST was significantly overestimated using the Fitbit® Charge (difference in means = 30 min; 95% confidence interval [CI] of difference: 3, 58; p = 0.031), while TWT was underestimated (difference = 23 min; 95% CI: 4, 42; p=0.018). All measures showed a lack of concordance between the Fitbit® Charge and PSG. CONCLUSIONS The current prospective study confirms that the Fitbit® Chargé overestimates time spent asleep compared to PSG in children with OSA/SDB symptoms, limiting the validity of sleep monitoring with wearable activity trackers appears in these patients.

Abstract
Dexmedetomidine use in the pediatric intensive care unit has increased in recent years. Reports of dexmedetomidine-associated drug fever have been described in adult patients; however, this has not been reported in the pediatric population. We report a case of persistent fever that resolved with the discontinuation of dexmedetomidine and successful transition to clonidine. This is the first report of dexmedetomidine drug fever in a pediatric patient.

Abstract
Background: Gaps in health insurance coverage may complicate asthma management and increase emergency department (ED) use. Using two nationally-representative surveys, we characterize the prevalence of coverage gaps among children with asthma, and describe their association with ED visits in this population. Methods: De-identified data were obtained from the 2016 National Survey of Children's Health (NSCH) and National Health Interview Survey (NHIS). Among children with asthma, we classified coverage over the past year as: (1) continuous private, (2) continuous public, (3) gap in coverage, and (4) continuously uninsured. The primary outcome was all-cause ED visits in the past year (both surveys). Secondary outcomes included unmet health care needs (NSCH), asthma-related ED visits or hospitalizations (NHIS) and asthma exacerbations (NHIS). Results: The analysis included 3739 (NSCH) and 854 (NHIS) children with asthma, representing a population of 5.5 million children in the US. Estimated prevalence of coverage gaps was 5% in the NSCH and 3% in the NHIS. On multivariable ordinal logistic regression using NSCH data, coverage gaps were associated with increased all-cause ED use (OR = 2.5; 95% CI: 1.3, 4.7, p = 0.005), compared to continuous private coverage. Further analysis confirmed higher odds of unmet health care needs, asthma exacerbations, and asthma-related ED visits among children with coverage gaps. Conclusions: Children with asthma who experience insurance coverage gaps have increased ED use, possibly related to poorer access to appropriate health care. Protecting insurance coverage continuity may reduce ED use and improve clinical outcomes in this population.

Abstract
Duchenne muscular dystrophy (DMD), first described in 1834, is an X-linked dystrophinopathy, leading to early onset skeletal muscle weakness. Life expectancy is reduced to early adulthood as a result of involvement of voluntary skeletal muscles with respiratory failure, orthopedic deformities, and associated cardiomyopathy. Given its multisystem involvement, surgical intervention may be required to address the sequelae of the disease process. We present a 36-year-old adult with DMD, who required anesthetic care during surgical debridement of an ischial pressure sore. Given his significant respiratory muscle involvement, ultrasound-guided caudal epidural anesthesia was used instead of general during the surgical procedure. The technique and its applications are discussed, with particular emphasis on the feasibility and safety of using regional anesthetic techniques in patients with DMD.
