We examined if midazolam premedication via oral (PO) vs. intravenous (IV) route in pediatric patients was associated with risk for deep sedation in the postanesthesia care unit. Medical records from May 2018 to December 2023 of patients aged 2–17 years premedicated with midazolam were reviewed and stratified according to administration route. Sedation level was classified using the Richmond Agitation–Sedation Scale: deeply sedated (≤ − 4) or not (≥ − 3). Inverse probability of treatment weighting (IPTW) analysis was performed to assess whether midazolam administration route was associated with postoperative deep sedation. Among 5245 pediatric patients, 608 (11.6

OBJECTIVE:Endotracheal intubation can cause laryngeal injury, with clinical presentation ranging from transient hoarseness to persistent vocal cord immobility. This study examines the incidence, clinical features, and outcomes of post-intubation laryngeal injuries following procedures traditionally considered low risk for such complications. METHODS:We conducted a retrospective review of adult patients who underwent tracheal intubation for surgical procedures between May 1, 2018, and December 31, 2024, and subsequently presented with postoperative laryngeal injury-related symptoms. Patients who underwent cardiothoracic, thyroid, parathyroid, or anterior cervical spine procedures were excluded. We reviewed patient demographics, airway and intubation characteristics, treatments, and clinical outcomes. RESULTS:Among 267 824 patients undergoing 454 924 general anesthetics, 30 developed postoperative laryngeal injury (6.6/100 000; 95% CI 4.5-9.4) which did not resolve spontaneously and required laryngology evaluation. Of these 22 (67%) had well defined movement abnormalities: unilateral (n = 15) and bilateral vocal cord immobility (n = 1), unilateral hypomobility (n = 4), bilateral hypomobility (n = 1), combined unilateral vocal cord immobility with contralateral hypomobility (n = 1), and 11 (33%) had no movement abnormality. Twenty-one (64%) were intubated via video laryngoscopy. Follow-up was available for 21 patients (70%) with a median [IQR] duration of 12 [9-35] months; 15 (72%) showed partial improvement without complete resolution, while 6 showed no improvement. CONCLUSION:Laryngeal injury following general anesthesia with tracheal intubation is a uncommon complication. In our series, approximately two-thirds of patients had identifiable injuries, while one-third exhibited no structural abnormality. While 75% of patients demonstrated partial symptomatic improvement, however, complete resolution was not observed in any of the patients who received follow-up in our institution, underscoring the severity of this complication.

Masseter muscle spasm after succinylcholine can herald malignant hyperthermia (MH) in genetically susceptible individuals. We aimed to describe the perioperative course and genetic findings in a patient who developed transient masseter spasm and postoperative rhabdomyolysis after general anesthesia. This single-patient case report draws on perioperative observations, laboratory testing, and whole-genome sequencing. Immediately after induction with propofol and succinylcholine, the patient experienced transient masseter spasm; anesthesia was then maintained with total intravenous anesthesia (propofol and remifentanil). Postoperatively, laboratory studies showed severe rhabdomyolysis with mild pigment nephropathy; the patient received intravenous hydration, laboratory values normalized by postoperative day 4, and discharge occurred in good condition. Whole-genome sequencing identified heterozygous ryanodine receptor 1 (RYR1) c.1840C>T (p.Arg614Cys)-a known MH-susceptibility variant in the skeletalmuscle ryanodine receptor-and butyrylcholinesterase (BCHE) c.293A>G (p.Asp98Gly), which reduces butyrylcholinesterase activity and delays succinylcholine hydrolysis. The coexistence of these variants likely synergistically increased sarcoplasmic reticulum Ca2+ release and prolonged succinylcholine effect, precipitating rhabdomyolysis; to our knowledge, this appears to be the first reported case linking concurrent RYR1 and BCHE variants to rhabdomyolysis following general anesthesia.

Background/Objectives: Adolescents with autonomic disorders who attend Intensive Interdisciplinary Pain Treatment (IIPT) programs report improvements in functioning. However, it is unclear whether they experience corresponding improvements in physiological measures. As such, the aim of this pilot study was to examine changes in physiological measures in youth attending an IIPT program who demonstrated excessive postural tachycardia on an active stand test. The secondary goal was to examine associations between physiological measurements and self-reported measures of chronic orthostatic intolerance (cOI) and functioning. Methods: At admission and discharge, eighteen adolescents and young adults (AYAs) attending IIPT (M age = 17.39 years; SD = 2.15 years) completed an active stand test, measures of breathing rate and muscle tension, as well as self-reported measures of cOI symptoms and functioning. Results: AYAs showed significant reduction in active stand test heart rate increase (p < 0.001; d = 1.07) and maximum heart rate (p = 0.002, d = 0.76) from admission to discharge. Improvements were also observed in resting respiration rate (p = 0.001, d = 89) and resting trapezoid tension (p = 0.03, d = 0.49). Although patients showed significant improvements on self-report measures of functioning (p < 0.001, d = 1.78), changes on subjective report of cOI symptoms did not reach significance. Exploratory analyses that only included patients with a POTS diagnosis were consistent with the overall results. Conclusions: Youth who demonstrated excessive postural tachycardia on active stand test at admission to an IIPT showed significant improvements from admission to discharge in their active stand maximum heart rate and heart rate increase, as well as respiration rate, muscle tension, and reports of their functioning. Future research is necessary to examine the mechanisms of change that contribute to symptom improvement.

Postural Orthostatic Tachycardia Syndrome (POTS) affects approximately 1% of adolescents, however, little research has been done in this area. This retrospective chart review describes the treatment goals and perceived progress as measured by the Canadian Occupational Performance Measure (COPM) of 111 adolescents and young adults (AYAs) aged 12-22 (M = 15.8, SD = 1.8) diagnosed with POTS who were admitted to an interdisciplinary intensive pain treatment program (IIPT). This study also examined the change in progress and satisfaction in goals over a 3-week intensive pain treatment program, as well as the utility and validity of the COPM as an outcome measure for AYAs attending an IIPT. Results indicated adolescents and young adults endorsed treatment goals focused on self-care, school, and leisure and found that performance and satisfaction scores significantly improved from admission to discharge. The findings also suggest that the COPM is a useful and valid outcome measure for this population.

Background Young adults with chronic pain and symptoms experience disruptions to their social, emotional, physical, and vocational functioning. Interdisciplinary pain rehabilitation programs for pediatric and adult populations are not designed specifically to address the developmental needs of young adults. Methods This article describes the development of a novel intensive interdisciplinary outpatient rehabilitation program tailored to the unique needs of young adults with chronic pain and symptoms. Tailored content included vocational assessment and consultation, financial literacy education, and sexual health education. Results Outcome data demonstrate treatment gains, with reductions in pain interference, pain severity, pain catastrophizing, and depressive symptoms, as well as improvements in mental and physical quality of life, perceived performance, perceived satisfaction with performance, and objective measures of physical functioning. Conclusions The article concludes with clinical recommendations for the management of chronic pain and symptoms in young adults, applicable across multiple treatment settings.

Importance: Estimates suggest that 1% of all teens struggle with Postural Orthostatic Tachycardia Syndrome. It can be a devastating condition for the adolescents who do not respond to the currently available pharmacologic and non-pharmacologic interventions. Preliminary data suggests that intensive interdisciplinary treatment may provide an effective intervention that can return these youth to normal functioning including full-time attendance at school, as well as reduce orthostatic symptoms, and psychological distress. Objective: To determine the effectiveness and durability of a 3-week interdisciplinary treatment in adolescents with Postural Orthostatic Tachycardia Syndrome in improving orthostatic symptoms, functioning, and psychological distress. Design: Patients diagnosed with Postural Tachycardia Syndrome admitted to an interdisciplinary treatment program were assessed at admission, discharge and 3-month follow-up to determine presence and severity of orthostatic symptoms, as well as functional status including return to school, and depression. Setting: An intensive interdisciplinary treatment program in a tertiary hospital outpatient setting. Participants: Forty-five adolescents ages 12-18 with confirmed diagnoses of Postural Tachycardia Syndrome referred to a tertiary medical center for interdisciplinary treatment. Intervention: A 3-week intensive outpatient interdisciplinary rehabilitation program with significant parental involvement based on a cognitive-behavioral model. Main Outcome and Measure(s): Self-reported orthostatic symptoms were assessed with the Compass 31; level of functioning was assessed with the Functional Disability Index, depressive symptoms were assessed with the Center for Epidemiological Studies-Depression for Children, and self-reported school attendance was assessed. Results: Significant improvements were observed and maintained at the end of treatment and at 3-month follow-up on measures of orthostatic symptoms, physical functioning, and psychological distress. At admission, 32% of patients had completed high school or were attending school full-time. At 3-month follow-up, 90% were either attending school full-time or had completed their schooling. Keywords: Postural Orthostatic Tachycardia Syndrome, POTS, interdisciplinary treatment, adolescents.

Objectives: Although biofeedback has been considered an effective treatment component for pediatric chronic pain, little research has examined the generalizability to activities outside of the treatment setting. The current study aimed to examine the effects of a biofeedback intervention involving individual and group sessions to facilitate increased self-regulatory skills for chronic pain management and to translate these skills to meaningful activities promoting functional restoration. Methods: Participants included 104 adolescents (ages 12-18) attending an intensive interdisciplinary pain rehabilitation program for chronic pain/symptoms and completed biofeedback training as part of the program. The biofeedback protocol consisted of six sessions, including an assessment of baseline physiologic states, diaphragmatic breath training, and various biofeedback screens to reinforce self-regulatory skills within individual- and group-based formats. Results: As expected, patients showed significant reductions in respiration rates and muscle tension from admission to discharge. Ratings of perceived confidence also increased from admission to post-treatment, suggesting greater self-efficacy in patients using self-regulatory skills during their daily functional activities. Conclusions: An individual- and group-based biofeedback protocol with a focus on training skills in activities relevant to adolescents' lives has the potential to improve self-regulation skills and generalize these skills to real-world settings. Future randomized controlled trials are necessary to examine the efficacy of biofeedback interventions to improve physiologic regulation and enhance treatment outcomes for pediatric chronic pain.

ABSTRACT: Objective: Postural orthostatic tachycardia syndrome (POTS) is estimated to occur in up to 1% of adolescents, with symptoms of dizziness, fatigue, and pain impacting daily functioning. However, many risk factors and symptoms for POTS overlap with those of youth with disordered eating, and adolescents with POTS may be at increased risk for developing eating disorders. Therefore, the present study sought to better understand this overlap. We hypothesized that patients with POTS would have higher than expected rates of weight change, restrictive eating patterns, and food sensitivities. Methods: We conducted a retrospective chart review of 96 adolescents and young adults diagnosed with POTS who were participating in a 3-week intensive interdisciplinary pain rehabilitation program. We conducted descriptive and correlational statistical analyses on data from self-report measures, biomarkers of nutritional status, and abstracted information about eating and weight concerns from medical notes. Results: Nearly 3 quarters of participants described engaging in restrictive eating, and more than half of them described experiencing weight loss. They also endorsed experiencing food allergies, celiac disease, and eating disorder at higher rates than would be expected in the general population. One-fifth of the sample had experienced invasive interventions to correct for nutritional imbalances, such as having a feeding tube. Conclusion: Weight and eating are clear areas of risk for patients with orthostatic intolerance. It is essential that treatment team members thoroughly screen for eating disturbances and make recommendations that support regular and balanced eating habits.

Although less recognized than other disruptions in functioning, individuals with chronic pain frequently display disturbances in eating associated with pain, changes in appetite, medication side effects, and prescribed elimination diets. Not only may changes in nutritional status and weight increase the risk for the development of an eating disorder, there is evidence that individuals with chronic pain and those with eating disorders share similar vulnerabilities that place them at risk for both conditions, as well as their comorbidity. This review will describe the temperamental, behavioral, and neurobiological risk factors linking chronic pain and eating disorders. We propose that these risk factors may reflect central sensitization, a condition of over-activation of the central nervous system that increases sensitivity to internal and external conditions. To manage high levels of sensitivity, individuals may develop unique patterns of behavioral avoidance, pain behaviors and/or restrictive eating. Using the framework of central sensitization, this review will discuss relevant assessment and intervention strategies to address sensitivity in eating disorders and chronic pain.

ObjectiveDespite ample research documenting deficits in executive functioning for adults with chronic pain, the literature on pediatric patients with chronic pain is limited and provides mixed results. The current study sought to further investigate the nature of executive dysfunction in this population and also examine the relationships between pain intensity, duration, and catastrophizing with sustained attention, working memory, and self- and parent-report of executive functioning.SettingsPediatric pain clinic and rehabilitation program.ParticipantsForty adolescents with chronic pain and their parents participated in this study.MethodsParticipants completed neuropsychological measures and standardized self-report questionnaires during a 45- to 60-minute testing session.ResultsFifty percent of this sample of adolescents with chronic pain demonstrated significant difficulties on at least one measure, with nine participants indicating difficulties on multiple measures. Pain significantly increased during the testing session. Pain variables of intensity, duration, and catastrophizing are related to sustained attention and working memory.ConclusionsThis study adds support to previous findings suggesting subclinical struggles with executive functioning for adolescents with chronic pain. One-half of the sample indicated difficulties in either sustained attention and/or working memory. Future studies that would more thoroughly examine more complex executive functioning skills in this population would be helpful to further guide multidisciplinary treatment of these patients, particularly regarding whether or not school accommodations are warranted.

Objective: This study examined key functional outcomes following a 3-week interdisciplinary pediatric pain rehabilitation program for adolescents with chronic pain. Maintenance of gains was evaluated at 3-month follow-up. Methods: Participants included 171 adolescents (12 to 18 y of age) with chronic pain who completed a hospital-based outpatient pediatric pain rehabilitation program. Participants completed measures of functional disability, depressive symptoms, pain catastrophizing, opioid use, school attendance, and pain severity at admission, discharge, and at 3-month follow-up. Results: Similar to other interdisciplinary pediatric pain rehabilitation program outcome studies, significant improvements were observed at the end of the program. These improvements appeared to be maintained or further improved at 3-month follow-up. Nearly 14% of the patients were taking daily opioid medication at admission to the program. All adolescents were completely tapered off of these medications at the end of the 3-week program and remained abstinent at 3-month follow-up. Discussion: This study adds to the available data supporting interdisciplinary pediatric pain rehabilitation as effective in improving functioning and psychological distress even when discontinuing opioids. Implications for future research and limitations of the study are discussed.

Introduction: Given that youth with chronic pain frequently experience disruptions in eating patterns that may place them at risk for disordered eating, the purpose of this study was to examine the clinical characteristics and illness course of adolescents with chronic pain and comorbid eating disorders.Methods: Using a retrospective chart review, 34 adolescents with chronic pain and concurrent eating disorders were identified. These adolescents were compared with 34 age-, gender-, and eating disorder symptom-matched adolescents who had an eating disorder without chronic pain.Results: The majority of adolescents with chronic pain and an eating disorder had a primary medical diagnosis of abdominal pain (n = 14), followed by autonomic dysfunction n = 10) and headache (n = 6). Although in 41.2% of teens with chronic pain, eating disorder symptoms developed after the onset of their pain, 35.3% reported having eating disorder symptoms before they experienced chronic pain. Body mass index did not differ between the groups, but the duration of eating disorder symptoms was significantly longer for the chronic pain group (p < .001).Discussion: Despite comparable severity, eating disorders are undetected for longer periods in patients with chronic pain, which may contribute to a poorer prognosis. Implications for eating disorder conceptualization, detection, and treatment are discussed.

OBJECTIVE:To describe the development of a clinically and financially successful interdisciplinary pediatric pain rehabilitation program at a large tertiary academic medical center and present demographic and clinical information on the first 1000 patients.PATIENTS AND METHODS:All patients who were consecutively admitted to this program between October 1, 2008, and March 31, 2015 were included in this review. The patients ranged in age from 9 to 24 years. The program is a 3-week, hospital-based outpatient treatment program that requires substantial parental involvement. At admission and discharge, patients completed the Center for Epidemiologic Studies of Depression Scale for Children, the Functional Disability Inventory, and the Pain Catastrophizing Scale for Children. Opioid use was also assessed.RESULTS:At admission, patients reported substantial pain-associated disability and depressive symptoms; they had elevated pain catastrophizing scores, and 16% were taking opioids. Primary sites/types of pain included head, abdomen, and generalized. Functional disability scores decreased significantly, from 27 to 9 after the program (P<.001). Depression scale scores improved from 27 to 14 (P<.001). Pain catastrophizing scores decreased significantly, from 26 to 14 (P<.001), at discharge from the program. All but 4 patients successfully tapered off of all opioid use by the conclusion of the program.CONCLUSION:Participation in a multidisciplinary pediatric pain rehabilitation program can be successful, with significant decreases in disability, depression symptoms, and pain catastrophizing, as well as discontinuation of opioid use.

Significant functional impairment and psychological distress have been observed in adolescent patients with postural orthostatic tachycardia syndrome (POTS). Interdisciplinary rehabilitation programs have been shown to be beneficial in the treatment of chronic pain in adults and adolescents. Only preliminary data have examined interdisciplinary rehabilitation efforts in patients with POTS. This study evaluated the impact of an interdisciplinary rehabilitation program on the functional impairment and psychological distress in 33 adolescents diagnosed with POTS. Patients included in the study were adolescents ages 11 to 18 diagnosed with POTS. Measures completed at admission and discharge from the program included the Functional Disability Index, Center for Epidemiological Studies–Depression–Child scale, and the Pain Catastrophizing Scale for Children. After participation in the 3-week program, adolescents with POTS demonstrated a significant increase in overall functional ability and significant reductions in depression and catastrophizing.

The prevalence of postural orthostatic tachycardia syndrome (POTS) in adolescents and young adults has been increasing during the past decade. Despite this increase, documentation regarding treatment of these patients is just beginning to emerge. In addition, despite a call for a multidisciplinary or interdisciplinary approach, no studies have examined the efficacy of such an approach to treatment. This paper describes a case study of a 19-year-old male with debilitating POTS seen at a tertiary clinic for evaluation and subsequent intensive interdisciplinary treatment. The treatment approach is described and outcomes are presented.
