Development of a Medical Complexity Score for Pediatric Aerodigestive Patients.

OBJECTIVE: To develop a complexity scoring system to characterize the diverse population served in pediatric aerodigestive clinics and help predict their treatment outcomes. STUDY DESIGN: A 7-point medical complexity score was developed through an iterative group consensus of relative stakeholders to capture the spectrum of comorbidities among the aerodigestive population. One point was assigned for each comorbid diagnosis in the following categories: airway anomaly, neurologic, cardiac, respiratory, gastrointestinal, genetic diagnoses, and prematurity. A retrospective chart review was conducted of patients seen in the aerodigestive clinic who had ≥2 visits between 2017 and 2021. The predictive value of the complexity score for the selected outcome of feeding progression among children with dysphagia was analyzed with univariate and multivariable logistic regression. RESULTS: We analyzed 234 patients with complexity scores assigned, showing a normal distribution (Shapiro Wilk P = .406) of the scores 1-7 (median, 4; mean, 3.50 ± 1.47). In children with dysphagia, there was waning success in the improvement of oral feeding with increasing complexity scores (OR, 0.66; 95% CI, 0.51-0.84; P = .001). Tube-fed children with higher complexity scores were incrementally less likely to achieve full oral diet (OR, 0.60; 95% CI, 0.40-0.89; P = .01). On multivariable analysis, neurologic comorbidity (OR, 0.26; P < .001) and airway malformation (OR, 0.35; P = .01) were associated with a decreased likelihood to improve in oral feeding. CONCLUSIONS: We propose a novel complexity score for the pediatric aerodigestive population that is easy to use, successfully stratifies diverse presentations, and shows promise as a predictive tool to assist in counseling and resource use.

Pediatric Aerodigestive Medicine: Advancing Collaborative Care for Children With Oropharyngeal Dysphagia.

OBJECTIVES: Aerodigestive disorders encompass various pathological conditions affecting the lungs, upper airway, and gastrointestinal tract in children. While advanced care has primarily occurred in specialty centers, many children first present to general pediatric gastroenterologists with aerodigestive symptoms necessitating awareness of these conditions. At the 2021 Annual North American Society for Pediatric Gastroenterology, Hepatology and Nutrition meeting, the aerodigestive Special Interest Group held a full-day symposium entitled, Pediatric Aerodigestive Medicine: Advancing Collaborative Care of Children with Aerodigestive Disorders. The symposium aimed to underline the significance of a multidisciplinary approach to achieve better outcomes for these complex patients. METHODS: The symposium brought together leading experts to highlight the growing aerodigestive field, promote new scientific and therapeutic strategies, share the structure and benefits of a multidisciplinary approach in diagnosing common and rare aerodigestive disorders, and foster multidisciplinary discussion of complex cases while highlighting the range of therapeutic and diagnostic options. In this article, we showcase the diagnostic and therapeutic approach to oropharyngeal dysphagia (OPD), one of the most common aerodigestive conditions, emphasizing the role of a collaborative model. CONCLUSIONS: The aerodigestive field has made significant progress and continues to grow due to a unique multidisciplinary, collaborative model of care for these conditions. Despite diagnostic and therapeutic challenges, the multidisciplinary approach has enabled and greatly improved efficient, high-quality, and evidence-based care for patients, including those with OPD.

Surgical management of complex neonatal airway abnormalities.

PURPOSE OF REVIEW: The neonatal airway is subject to a variety of developmental abnormalities with a wide range of complexity. Symptomatic pathologies present in a spectrum ranging from simple noisy breathing or poor feeding to frank respiratory distress. Diagnosis requires a high index of suspicion, characterization of noisy breathing, and identification of obstructive symptoms such as increased work of breathing, retractions, and difficulty feeding. Surgical management is directed by the pathology. RECENT FINDINGS: The past several years have seen an expansion of surgical innovation as endoscopic and open techniques have evolved. We reviewed articles related to neonatal and infant airway diagnoses since 2020 with the goal of providing a current review and update of developing techniques. Specifically, we discuss some of the exciting trends in surgical management of vocal fold paralysis, laryngeal clefts, subglottic stenosis, tracheobronchomalacia as well as the role of ex utero intrapartum therapy (EXIT procedures). SUMMARY: An underlying theme in evolving surgical management is the exciting advancements in technology, including 3-D printing, and expansion of minimally invasive endoscopic techniques. Though some of these developments are in the initial stages of utilization, they may be potential sources to transform surgical management in the future.

The steroid controversy: where are we?

Dexamethasone is widely administered to children during elective tonsillectomy to reduce the rate of postoperative nausea and vomiting, as well as decrease postoperative use of pain medications. Over the past two decades, there has been a wealth of literature advocating the practice that has led to endorsement by a variety of anesthesia and otolaryngology professional associations. However, the publication of a trial that was halted due to a potential dose-dependent association between postoperative hemorrhage and dexamethasone raised significant scrutiny regarding the practice in 2008. As a result, significant re-evaluation of existing data as well as the development and execution of additional trials have been pursued in recent years. Ultimately, the body of evidence that currently exists appears to support the concept that a single dose of perioperative dexamethasone is not associated with undue risk. A decision to withdraw dexamethasone from use in pediatric tonsillectomy needs to be weighed against the potential of causing increased postoperative nausea, vomiting, pain, and resultant hospital readmission. At this point, surgeons and anesthesiologists should feel comfortable giving perioperative dexamethasone but must remain vigilant for bleeding complications.

Dysphagia Outcomes Following Surgical Management of Unilateral Vocal Fold Immobility in Children: A Systematic Review.

OBJECTIVE: To assess dysphagia outcomes following surgical management of unilateral vocal fold immobility in children. DATA SOURCES: Ovid Medline, Embase, Web of Science, and CENTRAL databases. REVIEW METHODS: A systematic review of the medical literature was performed following the PRISMA guidelines. An a priori protocol was defined to identify all articles that presented quantifiable outcome data in children aged <18 years who underwent surgical treatment to improve glottal competence for dysphagia. Two authors independently determined references meeting the inclusion criteria, extracted data, and assigned levels of evidence. Data were pooled via a random effects model where possible. The quality of studies was graded with the MINORS criteria. RESULTS: An overall 398 publications were screened, with 9 meeting inclusion criteria. A total of 115 patients were included. Of these, 75% had preoperative swallowing symptoms. Surgical intervention for dysphagia included 61 injection laryngoplasties, 11 medialization laryngoplasties, and 10 reinnervations (ansa cervicalis to recurrent laryngeal nerve). The articles consistently reported success in improving dysphagia symptoms, and limited meta-analysis demonstrated a mean improvement after surgical intervention in 79% (95% CI, 67%-91%) of children. The reported rate of minor and major complications was 15% (95% CI, 1%-29%). The MINORS scores ranged from 5 to 12. CONCLUSION: Surgical management of unilateral vocal fold immobility in properly selected children can be an effective treatment for dysphagia when symptoms are present. Selection of surgical modalities relies on patient- and surgeon-related factors, and the rate of success is high across different interventions in treating these complex children.

Perioperative dexamethasone administration and risk of bleeding following tonsillectomy in children: a randomized controlled trial.

CONTEXT: Corticosteroids are commonly given to children undergoing tonsillectomy to reduce postoperative nausea and vomiting; however, they might increase the risk of perioperative and postoperative hemorrhage. OBJECTIVE: To determine the effect of dexamethasone on bleeding following tonsillectomy in children. DESIGN, SETTING, AND PATIENTS: A multicenter, prospective, randomized, double-blind, placebo-controlled study at 2 tertiary medical centers of 314 children aged 3 to 18 years undergoing tonsillectomy without a history of bleeding disorder or recent corticosteroid medication use and conducted between July 15, 2010, and December 20, 2011, with 14-day follow-up. We tested the hypothesis that dexamethasone would not result in 5% more bleeding events than placebo using a noninferiority statistical design. INTERVENTION: A single perioperative dose of dexamethasone (0.5 mg/kg; maximum dose, 20 mg), with an equivalent volume of 0.9% saline administered to the placebo group. MAIN OUTCOME MEASURES: Rate and severity of posttonsillectomy hemorrhage in the 14-day postoperative period using a bleeding severity scale (level I, self-reported or parent-reported postoperative bleeding; level II, required inpatient admission for postoperative bleeding; or level III, required reoperation to control postoperative bleeding). RESULTS: One hundred fifty-seven children (median [interquartile range] age, 6 [4-8] years) were randomized into each study group, with 17 patients (10.8%) in the dexamethasone group and 13 patients (8.2%) in the placebo group reporting bleeding events. In an intention-to-treat analysis, the rates of level I bleeding were 7.0% (n = 11) in the dexamethasone group and 4.5% (n = 7) in the placebo group (difference, 2.6%; upper limit 97.5% CI, 7.7%; P for noninferiority = .17); rates of level II bleeding were 1.9% (n = 3) and 3.2% (n = 5), respectively (difference, -1.3%; upper limit 97.5% CI, 2.2%; P for noninferiority < .001); and rates of level III bleeding were 1.9% (n = 3) and 0.6% (n = 1), respectively (difference, 1.3%; upper limit 97.5% CI, 3.8%; P for noninferiority = .002). CONCLUSIONS: Perioperative dexamethasone administered during pediatric tonsillectomy was not associated with excessive, clinically significant level II or III bleeding events based on not having crossed the noninferior threshold of 5%. Increased subjective (level I) bleeding events caused by dexamethasone could not be excluded because the noninferiority threshold was crossed.

Completion of postoperative polysomnography for children with severe obstructive sleep apnea: A quality improvement project.

Objective: Pediatric patients with severe obstructive sleep apnea (OSA) are at risk for residual OSA following tonsillectomy with/without adenoidectomy (T ± A). We initiated a quality improvement (QI) project to increase the percentage of postoperative (postop) polysomnography (PSG) completion to identify residual OSA. Methods: This is a prospective QI project carried out at a tertiary pediatric academic hospital. Children ≤18 years of age who underwent T ± A for severe OSA were included. Our Specific, Measurable, Attainable, Relevant, and Time-based (SMART) aim was to increase the percentage of completed postop PSGs in this cohort from a baseline of 70% to95% by May 31, 2021. We focused on patient education and leveraged both clinical decision support and reporting functionalities of the electronic medical record for project implementation. Results: During the pre-intervention period between January 1, 2019 to June 30, 2020, 472 patients met the inclusion criteria with an average age of 8.6 years (SD 4.6). The rate of postop PSG completion was 69.7% (SD 11.4%) with an average time of 99 days (SD 66) between surgery and the postop PSG. A shift was observed starting in September 2020, and the PSG completion rate improved to 94.9% by September 30, 2021. Post-intervention, there were 178 patients with an average age of 9.3 years (SD 4.9). The average time between surgery and the postop PSG was significantly reduced to 57 days (SD 16; p < .001). Conclusions: Through a multidisciplinary approach, we successfully completed our SMART aim. With the establishment of QI infrastructure, our goal is to deliver better care in a sustainable fashion using QI methodology.

Feasibility and accuracy of laryngeal ultrasound for the assessment of vocal cord mobility in children.

OBJECTIVE: Transcutaneous laryngeal ultrasonography has been utilized to document vocal cord mobility in the adult perioperative thyroidectomy setting with variable success. The aims of this study were to assess the feasibility of using transcutaneous ultrasound in vocal cord visualization in children, to determine the accuracy in detecting vocal cord immobility compare to flexible laryngoscopy, and to identify any barriers that may affect its utility. METHODS: This is a prospective blinded-assessor study. Transcutaneous laryngeal ultrasound and flexible laryngoscopy were performed in two pediatric settings: perioperative thyroid surgery and inpatient consultation for airway, voice, or swallowing concerns. The video recordings of ultrasound and laryngoscopy were assessed by two fellowship-trained pediatric otolaryngologists independently. RESULTS: A total of 83 paired laryngoscopy and ultrasound assessments were performed, 39 for perioperative thyroidectomy and 44 for inpatient consultation. The majority had normal vocal cord mobility (65/83, 78%), while 16 had unilateral cord palsy and 2 had bilateral palsy. The vocal cords were successfully visualized on ultrasound in 82/83 (99%) evaluations. Compared to gold standard laryngoscopy, the sensitivity for diagnosing vocal cord palsy on ultrasound was 53-83%, and the specificity was 97-98%. The sensitivity for detecting asymmetric vocal cord movement was 56-88%, and the specificity was 99%. The agreement between ultrasound and laryngoscopy diagnoses were 87-94% (κ = 0.58-0.83, moderate to near perfect agreement). The intra-rater agreement was 95-100% (κ = 0.64-1.0), and inter-rater agreement was 90% (κ = 0.66). Both subjects with bilateral vocal cord palsy had incorrect ultrasound diagnoses by both observers. CONCLUSION: We were able to utilize transcutaneous laryngeal ultrasound to successfully visualize vocal cord mobility in almost all pediatric patients with a high degree of specificity. The modality has limitations in the assessment of bilateral vocal cord palsy, and its sensitivity was observer-dependent.

Aortopulmonary collaterals: An etiology for pediatric tracheostomy hemorrhage.

OBJECTIVE: To report a single-institution's experience of symptomatic aortopulmonary collaterals presenting as tracheostomy tube hemorrhage. STUDY DESIGN: Retrospective case series and Contemporary Review. SETTING: Tertiary care children's hospital. METHODS: Retrospective review, from 2015 to 2020, of patients <18 years old who were treated for tracheostomy hemorrhage with endovascular embolization of aortopulmonary collateral (APC) vessels. RESULTS: 4 patients were identified, 2 males and 2 females, ages 15 months-to 14 years-old, with a range of cyanotic congenital heart diseases. Direct laryngoscopy and bronchoscopy were necessary for excluding proximal airway sources. Chest computed tomography angiography did not localize pulmonary hemorrhage, but helped identify aortopulmonary collaterals. Cardiac catheterization was both diagnostic and therapeutic with use of endovascular embolization techniques by pediatric interventional cardiology and interventional radiology. Previously reported APC-related pulmonary hemorrhages occurred in significantly different settings compared to our patients, and evaluation by an otolaryngologist was key to rule out upper airway etiologies. CONCLUSION: Symptomatic aortopulmonary collaterals is an important etiology in pediatric tracheostomy tube hemorrhage in patients with cyanotic congenital heart disease.

Bronchial stenting in infants with severe bronchomalacia: Technique and outcomes.

OBJECTIVES: To report the first use of a balloon expandable bare metal stent for treating infant bronchomalacia. BACKGROUND: Infant bronchomalacia often requires prolonged mechanical ventilation and can be life-threatening. Effective treatment for severe infant bronchomalacia continues to be elusive. We present three cases of bronchial stenting for no-option or treatment refractory infant bronchomalacia. METHODS: Three consecutive cases of stenting to relieve conservative treatment refractory severe infant bronchomalacia were performed between February 2019 and December 2020. Initial diagnosis was confirmed with Computed Tomography (CT) angiography. Patients underwent rigid micro laryngoscopy, bronchoscopy, and flexible bronchoscopy to evaluate the airway. Initial conservative management strategies were pursued. Patients failing initial conservative management strategies were considered for rescue bronchial stenting. RESULTS: Our initial clinical experience with a coronary bare metal stent for these procedures has been favorable. The stent was easy to deploy with precision. We did not encounter stent embolization or migration. There was sufficient stent radial strength to relieve bronchomalacia without causing restenosis or erosion. There was no significant granulation tissue formation. In one patient, the stent was removed after 12 months of somatic growth; this was uneventful and bronchial patency was maintained. There were no complications in any of our patients regarding stent placement and reliability. CONCLUSION: In cases of three infants with severe bronchomalacia, we found that bronchial stenting with the bare metal coronary stent was effective in relieving bronchial stenosis.

The role of bioresorbable intraluminal airway stents in pediatric tracheobronchial obstruction: A systematic review.

INTRODUCTION: Tracheal stenosis and tracheobronchomalacia are complicated, patient-specific diseases that can be treated with intraluminal stenting. Most commonly, silicone and metal stents are utilized, however, they pose significant early and late morbidity and are further complicated by growth of the airway in the pediatric population. Given recent improvements in materials science, there is a growing body of evidence suggesting a strong role for bioresorbable intraluminal stents in treating pediatric tracheobronchial obstruction. METHODS: A PubMed.gov literature search was performed on December 3, 2019 and May 15, 2020, and a 2-researcher systematic review was performed following the PRISMA criteria. The following search query was utilized: (((((((bioresorbable) OR bioabsorbable) OR resorbable) OR absorbable) OR biodegradable AND airway) OR trachea) AND stent. A pooled statistical analysis was performed on all reported pediatric patients using SPSS software. RESULTS: 1369 publications were screened and 26 articles with original data were identified. Materials used included polydioxanone (PDO), poly-l-lactic acid (PLLA), polyglycolic acid/poly-l-lactide co-polymer with Proglactin 910 (Vicryl®-PDS®), polycaprolactone (PCL), magnesium alloys, and co-polymers in varying proportions. Twelve articles presented data on human subjects, 8 of which were case series and case reports on pediatric populations using polydioxanone (PDO) stents. Pooled statistical analysis demonstrated an average age of 19 months (range 0.25-144), 56.5% associated with a cardiovascular anomaly, and overall complication rate of 21.7%, with a stent fragment foreign body being the most common (8.7%), followed by significant granulation tissue (4.3%), stent migration (4.3%), and local stenosis (4.3%). Comparative analysis demonstrated short-term improvement (up to 1 month) has a statistically significant association with tracheobronchomalacia versus tracheal stenosis on chi-squared test (p = 0.001). The remaining analyses did not yield statistical significance. CONCLUSION: The reported application of bioresorbable materials as intraluminal airway stents is positive. All comparative animal studies report biocompatibility and fewer morbidities compared to metal and silicone stents, however, in human studies there are concerns over the short interval of degradation and the potential for obstructive foreign bodies in poorly seated stents. Overall, there are clear, reproducible advantages to bioresorbable intraluminal stents in pediatric airway obstruction, as well as common pitfalls, that warrant further research.

Pediatric Dysphonia: A Cross-Sectional Survey of Subspecialty and Primary Care Clinics.

OBJECTIVES: Prevalence data for pediatric dysphonia are sparse and primarily collected either in the community or within pediatric otolaryngology clinics. The objectives were to determine the prevalence of dysphonia in children undergoing outpatient medical evaluation, and to ascertain whether the prevalence varies across pediatric subspecialty clinic populations in comparison to primary care. STUDY DESIGN: Cross-sectional survey. SETTING: Tertiary care military medical center. SUBJECTS AND METHODS: Five hundred sixteen surveys were administered to caregivers of children undergoing evaluation in pediatric primary care and subspecialty clinics consisting of the pediatric voice-related quality of life (PVRQOL) instrument and questions regarding previous voice-related symptoms and diagnoses. Survey responses and PVRQOL scores were stratified by clinic type and compared to general pediatrics. RESULTS: A total of 492 surveys were analyzed. The overall prevalence of dysphonia in this cohort based on PVRQOL is 19.3%. Every clinic except endocrinology and ophthalmology individually had an elevated prevalence compared to the expected community prevalence (11%). Compared to general pediatrics, PVRQOL scores were lower in developmental pediatrics (P < 0.001), genetics (P < 0.001), and otolaryngology (P = 0.033) clinics. Children from genetics and developmental pediatrics were more likely to have had speech therapy. CONCLUSIONS: In this cohort of children seeking care within a medical center, overall prevalence of dysphonia was quite high in comparison to community-based prevalence data. Not surprisingly, patients of developmental pediatrics, genetics and pediatric otolaryngology have lower PVRQOL scores than primary care. These results emphasize that all practitioners caring for children should seek to identify voice disorders and reinforce that subspecialists who treat developmentally challenged children should exert particular vigilance.

Auricular acupuncture for adult tonsillectomy.

OBJECTIVES: Adult tonsillectomy causes significant postoperative pain that can last over 14 days, but narcotic regimens only provide a modest reduction in pain. Auricular acupuncture has been demonstrated to improve pain with minimal complications. This study compared acupuncture versus control for pain, opioid consumption, nausea, and return of diet and activity following tonsillectomy. METHODS: A prospective, single-blinded randomized controlled trial was performed on 134 adults undergoing tonsillectomy at a tertiary care teaching hospital. Each patient was randomized to receive either auricular (Battlefield protocol) acupuncture with auricular bandages or bandages alone while under general anesthesia. Subjects journaled daily postoperative pain, diet, activity, and opioid consumption, then returned to the clinic on postoperative day 14 for a final questionnaire and evaluation. RESULTS: Ninety-nine patients completed the study with 50 patients in the acupuncture group and 49 patients in the control group. Pain scores for the acupuncture group following tonsillectomy were significantly lower than the control group on the day of surgery (2.9, 4.3; P = .01), but there was no statistically significant difference in pain thereafter. There was an equivalent level of postoperative narcotic usage, nausea, emesis, functional activity and diet between the two groups. The main complication following tonsillectomy was secondary hemorrhage and there was no significant difference between the two groups (20%, 10%; P = .13). CONCLUSION: Auricular acupuncture provides increased pain relief on the day of surgery, an effect that seems to diminish after 24 hours. LEVEL OF EVIDENCE: 1b Laryngoscope, 130: 1907-1912, 2020.

Predictors of Pediatric Tracheostomy Outcomes in the United States.

OBJECTIVES: To investigate the outcomes of pediatric tracheostomy as influenced by demographics and comorbidities. STUDY DESIGN: Retrospective national database review. SETTING: Fifty-two children's hospitals across the United States. SUBJECTS AND METHODS: Hospitalization records from Pediatric Health Information System database dated 2010 to 2018 with patients younger than 18 years and procedure codes for tracheostomy were extracted. The primary outcome was total length of stay. The secondary outcomes were 30-day readmission, mortality, and posttracheostomy length of stay. RESULTS: A total of 14,155 children were included in the analysis. The median total length of stay was 77 days and increased from 59 to 103 days between 2010 and 2018 (P < .001). The median posttracheostomy length of stay was 34 days and also increased from 27 to 49 days (P < .001). On multivariate regression analyses, the total and posttracheostomy lengths of stay were significantly increased in children younger than 1 year, patients of black race, hospitals in the non-West regions, those discharged to home, and those with comorbidities. Socioeconomic indicators such as insurance type and estimated household income were associated with no difference or small effect sizes. Regions and comorbidities were associated with differences in 30-day readmission (overall 26%), while in-hospital mortality was primarily associated with age and comorbidities (overall 8.6%). CONCLUSION: Pediatric tracheostomy requires substantial health care resources with length of stay escalating over recent years. Age, race, region, discharge destination, and comorbidities were associated with differences in length of stay.

The role of 3D printing in pediatric airway obstruction: A systematic review.

BACKGROUND: Tracheomalacia and tracheal stenosis are complicated, patient-specific diseases that require a multidisciplinary approach to diagnose and treat. Surgical interventions such as aortopexy, slide tracheoplasty, and stents potentially have high rates of morbidity. Given the emergence of three-dimensional (3D) printing as a versatile adjunct in managing complex pathology, there is a growing body of evidence that there is a strong role for 3D printing in both surgical planning and implant creation for pediatric airway obstruction. METHODS: A structured PubMed.gov literature search was utilized, and a two-researcher systematic review was performed following the PRISMA criteria. The following search query was utilized: (((((3D printing) OR three-dimensional printing) OR 3D printed) OR three-dimensional printed) AND trachea) OR airway. RESULTS: Over 23,000 publications were screened. Eight literature reviews and thirty-seven original papers met inclusion criteria. Of the thirty-seven original papers, eleven discussed 3D printing for surgical planning and twenty-six discussed 3D printing implants for interventions. CONCLUSION: The reported application of 3D printing for management of pediatric airway obstruction is emerging with positive and broad applications. 3D printing for surgical planning not only improves pre-operative assessment of surgical approach and stent customization, but also helps facilitate patient/family education. 3D printing for custom implantable interventions is focused on bioresorbable external airway splints and biological grafts, with both animal studies and human case reports showing good results in improving symptoms.

International Pediatric Otolaryngology Group (IPOG): Consensus recommendations on the prenatal and perinatal management of anticipated airway obstruction.

OBJECTIVE: To make recommendations on the identification, routine evaluation, and management of fetuses at risk for airway compromise at delivery. METHODS: Recommendations are based on expert opinion by members of the International Pediatric Otolaryngology Group (IPOG). A two-iterative Delphi method questionnaire was distributed to all members of the IPOG and responses recorded. The respondents were given the opportunity to comment on the content and format of the survey, which was modified for the second round. "Consensus" was defined by >80% respondent affirmative responses, "agreement" by 51-80% affirmative responses, and "no agreement" by 50% or less affirmative responses. RESULTS: Recommendations are provided regarding etiologies of perinatal airway obstruction, imaging evaluation, adjunct evaluation, multidisciplinary team and decision factors, micrognathia management, congenital high airway obstruction syndrome management, head and neck mass management, attended delivery procedure, and delivery on placental support procedure. CONCLUSIONS: Thorough evaluation and thoughtful decision making are required to optimally balance fetal and maternal risks/benefits.

Advanced practice providers and children's hospital-based pediatric otolarynology practices.

INTRODUCTION: Advanced practice providers (APPs), including nurse practitioners and physician assistants, have been deployed in children's hospital-based academic pediatric otolaryngology practices for many years. However, this relationship in terms of prevalence, roles, financial consequences and satisfaction has not been examined. The objective of this study is to explore how APPs impact healthcare delivery in this setting. METHODS: Pediatric otolaryngology chiefs of all academic children's hospitals in the US were electronically surveyed about the ways APPs intersected clinically and financially in their respective practice. RESULTS: A total of 29 of 36 children's hospital-based pediatric otolaryngology practices completed the survey, of which 26 practices (90%) utilized APP. There were large variances within the APP practice cohort in faculty size (mean/median/range = 9.4/8.5/3-29); annual patient visits (mean/median = 18,373/17,600); number of practice site (mean/median/range = 4.3/4/2-9) and number of outpatient APP (mean/median/range = 6.3/5/1-30). No factors (faculty size, annual visits and number of practice sites) differentiated between the APP and non-APP practices. Among APP practices, significant correlation (p<.00001) was observed between size of APP cohort to faculty size and annual visits. 69% of the practices did not differentiate job functions of nurse practitioners and physician assistants. 85% of the practices utilized APPs in all practice sites and 19% utilized APPs in the operating room. 77% of APPs billed independently and 46% had on-site supervision. The most prevalent APP salary bracket based on 0-5, 6-10 and > 11 years of tenure were $76-100K (65%), $100-150K (77%) and $100-150K (86%), respectively. In 46% of the practices, APPs were able to generate enough revenue to cover more than 75% of their salary and 23% of practices generated a profit. 81% of the chiefs ranked the effectiveness of APPs as high (4 and 5) on a 5-point Likert scale. DISCUSSION: The majority of academic pediatric otolaryngology practices employed APPs. Despite the diversity seen in practice complexity, APP functionality and financial impact, most found the APP model to be beneficial in improving patient care, patient access and faculty productivity.

Serial electromyography of the thyroarytenoid muscles using the NIM-response system in a canine model of vocal fold paralysis.

OBJECTIVES: We sought to determine whether serial intraoperative laryngeal electromyography (L-EMG) or evoked L-EMG predicts vocal fold (VF) recovery following iatrogenic injury. METHODS: Six beagles were sedated, and bipolar needle electrodes were inserted into each thyroarytenoid (TA) muscle. Endotracheal tube surface electrodes were also placed. As the sedation lightened, L-EMG activity was recorded from all electrodes with an intraoperative nerve monitoring system. The neck was opened, and direct recurrent laryngeal nerve (RLN) stimulation was performed. Subsequently, 4 animals underwent crush injury of the left RLN,and 2 animals underwent nerve transection. The L-EMG procedures were repeated every 1 to 2 weeks until left VF motion was observed in the dogs that suffered RLN crush injury. At each time point, the neck was opened and both RLNs were stimulated. RESULTS: Fibrillation potentials were detected in all animals after RLN injury. A change to electrical silence was seen in the animals in the crush injury group that were evaluated during the week preceding VF recovery. Fibrillation potentials and VF immobility persisted in the transection group throughout the complete time course of these experiments. The first appearance of an evoked response coincided with or occurred after the return of left VF motion in the crush injury group. The threshold, latency, and amplitude differed from those of the controls and approached normal values over time. No response was detected in the transected nerves. CONCLUSIONS: The disappearance of fibrillations on intraoperative L-EMG was noted in the animals tested the week before the return of VF motion, and the return of motor unit action potentials was seen along with return of VF function. Evoked L-EMG was not helpful in predicting the return of VF mobility, but it may help quantify degrees of RLN injury and predict the speed of recovery.
