Assessment of risk factors for adverse events in analgosedation for pediatric endoscopy: A 10-year retrospective analysis.

OBJECTIVES: Data regarding the occurrence of complications specifically during pediatric anesthesia for endoscopic procedures is limited. By evaluating such data, factors could be identified to assure proper staffing and preparation to minimize adverse events and improve patient safety during flexible endoscopy. METHODS: This retrospective cohort study included children undergoing anesthesia for gastroscopy, colonoscopy, bronchoscopy, or combined endoscopic procedures over 10-year period. The primary study aim was to evaluate the incidence of complications and identify risk factors for adverse events. RESULTS: Overall, 2064 endoscopic procedures including 1356 gastroscopies (65.7%), 93 colonoscopies (4.5%), 235 bronchoscopies (11.4%), and 380 combined procedures (18.4%) were performed. Of the 1613 patients, 151 (7.3%) patients exhibited an adverse event, with respiratory complications being the most common (65 [3.1%]). Combination of gastrointestinal endoscopies did not lead to an increased adverse event rate (gastroscopy: 5.5%, colonoscopy: 3.2%). Diagnostic endoscopy as compared to interventional had a lower rate. If bronchoscopy was performed, the rate was similar to that of bronchoscopy alone (19.5% vs. 20.4%). Age < 5.8 years or body weight less than 20 kg, bronchoscopy, American Society of Anesthesiologists status ≥ 2 or pre-existing anesthesia-relevant diseases, and urgency of the procedure were independent risk factors for adverse events. For each risk factor, the risk for events increased 2.1-fold [1.8-2.4]. CONCLUSIONS: This study identifies multiple factors that increase the rate of adverse events associated anesthesia-based endoscopy. Combined gastrointestinal procedures did not increase the risk for adverse events while combination of bronchoscopy to gastrointestinal endoscopy showed a similar risk as bronchoscopy alone.

Utilization of immediate extubation in a multidisciplinary pathway for pediatric liver transplantation associated with improved postoperative outcomes.

BACKGROUND: Immediate extubation is becoming more common in liver transplantation. However, limited data exist on how to identify pediatric patients with potential for successful immediate extubation and how this intervention may affect recovery. METHODS: This retrospective review evaluated patients who underwent liver transplantation from 2015 to 2021 at Children's Healthcare of Atlanta. Preoperative status and intraoperative management were evaluated and compared. Outcomes comprised thrombosis, surgical reexploration, retransplantation, as well as reintubation, high flow nasal cannula (HFNC) usage, postoperative infection, the length of stay (LOS), and mortality. RESULTS: A total of 173 patients were analyzed, with 121 patients (69.9%) extubated immediately. The extubation group had older age (median 4.0 vs 1.25 years, p = .048), lower PELD/MELD (28 vs. 34, p = .03), decreased transfusion (10.2 vs. 41.7 mL/kg, p < .001), shorter surgical time (332 vs. 392 min, p < .001), and primary abdominal closure (81% vs. 40.4%, p < .001). Immediate extubation was associated with decreased HFNC (0.21 vs. 0.71 days, p = .02), postoperative infection (9.9% vs. 26.9%, p = .007), mortality (0% vs. 5.8%, p = .036), and pediatric intensive care unit LOS (4.7 vs. 11.4 days, p < .001). The complication rate was lower in the extubation group (24.8% vs. 36.5%), but not statistically significant. CONCLUSIONS: Approximately 70% of patients were able to be successfully extubated immediately, with only 2.5% requiring reintubation. Those immediately extubated had decreased need for HFNC, lower infection rates, shorter LOS, and decreased mortality. Our results show that with proper patient selection and a multidisciplinary approach, immediate extubation allows for improved recovery without increased respiratory complications after pediatric liver transplantation.

Transcutaneous carbon dioxide monitoring in children undergoing rigid bronchoscopy: a prospective blinded observational study.

PURPOSE: Anesthetic management during rigid bronchoscopy in children can be challenging, and continuous end-tidal carbon dioxide (EtCO2) monitoring is often unachievable. Transcutaneous carbon dioxide (TcCO2) monitoring is strongly correlated with the partial pressure of carbon dioxide (PaCO2) and EtCO2. We aimed to investigate the incidence of hypercapnia in children undergoing rigid bronchoscopy. METHODS: We enrolled patients aged < 18 yr scheduled for rigid bronchoscopy in a prospective observational study. We recorded TcCO2 values from anesthesia induction to the postanesthesia care unit (PACU) stay. We ended monitoring when TcCO2 reached values ≤ 50 mm Hg. The operating room (OR) team was blinded to the TcCO2. The outcome of primary interest was the incidence of hypercapnia (TcCO2 > 50 mm Hg) in the OR. Other outcomes were the incidences of hypercapnia in the PACU and severe hypercapnia (TcCO2 > 90 mm Hg), factors possibly related to hypercapnia (patient, surgery, or anesthesia factors), and the incidence of perioperative adverse events. RESULTS: A total of 30 patients were enrolled. The median [interquartile range (IQR)] age was 3.5 [1.5-8.0] yr. The incidence of hypercapnia was 100% in the OR and 60% in the PACU. Five cases (17%) presented with severe hypercapnia in the OR. The highest median [IQR] TcCO2 was 69 [61-79] mm Hg. The most common adverse event was oxygen desaturation (57%, 17/30). Patients with severe hypercapnia had long stays in the PACU. CONCLUSION: Hypercapnia was a frequent event in children undergoing rigid bronchoscopy and severe hypercapnia was associated with a long PACU stay. Further studies are needed to assess the utility of TcCO2 monitoring in guiding ventilatory interventions during these cases.

RéSUMé: OBJECTIF: La prise en charge anesthésique pendant la bronchoscopie rigide chez les enfants peut être difficile, et le monitorage de la pression télé-expiratoire en CO2 (EtCO2) est souvent irréalisable. Le monitorage du dioxyde de carbone transcutané (TcCO2) est fortement corrélé à la pression partielle de dioxyde de carbone (PaCO2) et à l'EtCO2. Notre objectif était d'étudier l'incidence d'hypercapnie chez les enfants bénéficiant d'une bronchoscopie rigide. MéTHODE: Nous avons recruté des patient·es âgé·es de moins de 18 ans qui devaient bénéficier d'une bronchoscopie rigide dans une étude observationnelle prospective. Nous avons enregistré les valeurs de TcCO2 de l'induction de l'anesthésie au séjour en salle de réveil. Nous avons mis fin au monitorage lorsque le TcCO2 a atteint des valeurs ≤ 50 mm Hg. Les valeurs de TcCO2 n'étaient pas visibles pour l'équipe en salle d'opération (SOP). Le critère principal d'intérêt était l'incidence d'hypercapnie (TcCO2 > 50 mm Hg) en SOP. Les autres critères évalués étaient l'incidence d'hypercapnie en salle de réveil et d'hypercapnie sévère (TcCO2 > 90 mm Hg), les facteurs possiblement liés à l'hypercapnie (facteurs du/de la patient·e, de la chirurgie ou de l'anesthésie) et l'incidence d'événements indésirables périopératoires. RéSULTATS: Au total, 30 patient·es ont été recruté·es. L'âge médian [écart interquartile (ÉIQ)] était de 3,5 [1,5 à 8,0] ans. L'incidence d'hypercapnie était de 100% dans la salle d'opération et de 60% en salle de réveil. Cinq cas (17%) ont présenté une hypercapnie sévère en salle d'opération. Le TcCO2 médian [ÉIQ] le plus élevé était de 69 [61­79] mm Hg. L'effet indésirable le plus fréquent était la désaturation en oxygène (57%, 17/30). Les patient·es atteint·es d'hypercapnie sévère ont fait de longs séjours en salle de réveil. CONCLUSION: L'hypercapnie était un événement fréquent chez les enfants bénéficiant d'une bronchoscopie rigide et l'hypercapnie sévère était associée à un long séjour en salle de réveil. D'autres études sont nécessaires pour évaluer l'utilité du monitorage du TcCO2 dans l'orientation des interventions ventilatoires au cours de ces cas.

An ambulatory dental treatment of a child with Rett syndrome and limited mouth opening under muscle relaxant-free general anesthesia: a case report.

BACKGROUND: Rett Syndrome (RTT) is a rare, severe, and progressive developmental disorder with intellectual disability. Anesthesia in RTT patients presents a range of challenges. We report a child with RTT who received dental treatment under muscle relaxant-free general anesthesia in our ambulatory center. CASE PRESENTATION: A 15-year-old girl with RTT was admitted to our dental clinic with multiple dental caries and residual roots. Dental treatment was scheduled under ambulatory general anesthesia. After anesthesia induction, a nasal tube was initiated under the guidance of a fiberoptic bronchoscope. Multimodal analgesia, body temperature monitoring, and postoperative nausea and vomiting prevention were applied. No muscle relaxants were used throughout the process. The endotracheal tube was successfully removed after the operation and the patient was discharged home the same day. CONCLUSION: An individualized anesthesia strategy enabled a quick and safe recovery for this RTT patient after dental treatment under muscle relaxant-free general anesthesia.

Pediatric anesthesia training in Israel and Palestine: Realities versus expectations.

Israel is a young country with a rather young system of medical education. This educational review serves to illuminate the similarities and differences in the training of a pediatric Anesthesiologist in both Israel and Palestine.

Airway topicalization in pediatric anesthesia: An international cross-sectional study.

BACKGROUND: There is no national or international consensus or guideline on recommended dosing of lidocaine for airway topicalization in children. Doses quoted in the literature vary substantially. AIMS: The primary aim of the study was to ascertain current international dosing practices (mg.kg-1 and concentration of solution) for lidocaine airway topicalization in children. The secondary aims included examining aftercare instructions for those receiving lidocaine airway topicalization and instances of local anesthetic systemic toxicity secondary to the use of lidocaine for airway topicalization in pediatric patients. METHODS: This cross-sectional study consisted of 11-20 questions across three domains-population demographics, clinical practice, and local anesthetic systemic toxicity. It adhered to the consensus-based checklist for reporting of survey studies. Responses were collected over 14 weeks using a combination of probability (cluster and simple random) and nonprobability (purposive, convenience and snowball) sampling. Data were analyzed based on the response rate per question with proportions expressed as percentages and nonparametric data expressed as median (interquartile range [range]) in an effort to minimize nonresponse error. No weighting of items or propensity scoring was applied. RESULTS: After initial exclusions, 1501 participants from 69 countries, across six continents, were included. Consultant anesthetists or those with an equivalent level of experience accounted for 1262/1501 (84.1%) of responses. Results showed heterogeneity in dosing and timing regimens and evidence that dosing may contribute to adverse outcomes. The maximum dose reported by participants who use lidocaine for airway topicalization as part of their normal practice was 5 mg.kg-1 (4-6 mg.kg-1 [0.5-50]) median (interquartile range [range]) over 2 h (1-4 h [0-30]). CONCLUSION: The results support the need for further research and consensus in this area, in order to provide safe provision of lidocaine airway topicalization in children. It is hoped the results of this study can support future collaborative work in this area.

Global pediatric anesthesia-Anglophone West Africa perspective.

BACKGROUND: This article gives the pediatric anesthesia perspective from Cameroon, Nigeria, Ghana, Liberia, and Gambia, five out of six countries in Anglophone West Africa. Over 40% of the population of most of these countries are younger than 14 years and there is an increasing need for paediatric anesthesia services. FINDINGS: Workforce density ranges from 0.08 to 0.58 physician anesthesia providers per 100,000 population. There are only 13 trained pediatric anesthetists; ratios range from 0 to 0.4 per 100,000 children, thus pediatric anesthesia services are provided by various cadres of physician and non-physician anesthesia providers. Physician anesthesia training is mostly carried out by the West African College of Surgeons as well as national postgraduate colleges. Pediatric anesthesia services are provided in tertiary (teaching), secondary (general), district, faith-based, military, private hospitals and through surgical missions. Challenges include lack of trained personnel, high morbidity from late presentation to health facilities and financial constraints, lack of health insurance for pediatric anesthesia services, unavailability of appropriate equipment and consumables, a narrow range of medications, very few pediatric-specific operating theaters, and inadequate critical care services. SOLUTIONS: The lack of opportunities for sub-specialty training in pediatric anesthesia in West Africa is currently being addressed in Nigeria and Ghana. Non-governmental agencies fund programs and courses related to pediatric anesthesia and have also provided fully equipped operating theaters. Advocacy for pediatric anesthesia can be achieved through the National Surgical Obstetric Anesthesia and Nursing Plans Implementation Committee of the various countries. There is an urgent need for prioritization of health in the budgets of Anglophone West African countries and governments must deliberately provide support for anesthesia and surgical services. More international collaborations towards workforce training and creation of children's hospitals are needed.

The effect of intraoperative methadone on postoperative opioid requirements in children undergoing orchiopexy: A randomized clinical trial.

BACKGROUND: Children undergoing outpatient surgery are at risk of inadequate postoperative pain control. Methadone has a long duration of action and an intraoperative dose may provide stable analgesia throughout the postoperative period. Intraoperative methadone has been shown to improve pain control in adolescents but its use for postoperative pain in pediatric patients undergoing outpatient surgery has not been studied before. Therefore, we conducted a double-blind randomized placebo-controlled trial to investigate the effects of a single dose of intraoperative methadone in children aged less than 5 years undergoing orchiopexy for undescended testis. METHODS: A total of 68 children were randomized to receive either methadone (0.1 mg/kg) or isotonic saline following induction of anesthesia. Exclusion criteria included preterm birth, previous scrotal surgery, and parents' inability to consent. Primary outcomes were opioid requirements (first primary outcome) and pain intensity in the post-anesthesia care unit. Secondary outcomes included episodes of desaturation and time until readiness to discharge from the post-anesthesia care unit, sleep on the first postoperative night, pain intensity, and opioid requirements at home until the evening on the first postoperative day. Follow-up was 4 days. RESULTS: Sixty children completed the study (age, mean ± SD, 26.2 ± 13.9 months), 29 children received methadone, and 31 children received placebo. Eighteen children required opioids in the post-anesthesia care unit, five children in the methadone group (proportion = 0.17, 95% confidence interval (CI): 0.07, 0.36) compared to thirteen patients in the placebo group (0.42, 95% CI: 0.26, 0.60) (mean difference = -0.24 and 95% CI: -0.03, -0.47) (p = 0.037). Five children in the methadone group (0.17, 95% CI: 0.03, 0.31) versus ten in the placebo group (0.32, 95% CI: 0.16, 0.49) had a face, legs, activity, cry, consolability score of ≥5 in the post-anesthesia care unit (mean difference = -0.15, 95% CI: -0.36, 0.06) (p = .179). More children in the placebo group woke up due to pain the first night following surgery (seven children vs. one child). The methadone group had a longer stay in the post-anesthesia care unit. There were no differences between the two groups regarding the other secondary outcomes. CONCLUSION: A single dose of intraoperative methadone reduces short-term postoperative opioid requirements in children after orchiopexy for nondescended testes but prolongs the duration of their stay in the post-anesthesia care unit.

Assessment of the antinociceptive effect of a single fentanyl bolus dose in children: A pharmacokinetic and pharmacodynamic analysis based on the nociception level index during sevoflurane general anesthesia.

BACKGROUND: The Nociception Level Index has shown benefits in estimating the nociception/antinociception balance in adults, but there is limited evidence in the pediatric population. Evaluating the index performance in children might provide valuable insights to guide opioid administration. AIMS: To evaluate the Nociception Level Index ability to identify a standardized nociceptive stimulus and the analgesic effect of a fentanyl bolus. Additionally, to characterize the pharmacokinetic/pharmacodynamic relationship of fentanyl with the Nociception Level Index response during sevoflurane anesthesia. METHODS: Nineteen children, 5.3 (4.1-6.7) years, scheduled for lower abdominal or urological surgery, were studied. After sevoflurane anesthesia and caudal block, a tetanic stimulus (50 Hz, 60 mA, 5 s) was performed in the forearm. Following the administration of fentanyl 2 µg/kg intravenous bolus, three similar consecutive tetanic stimuli were performed at 5-, 15-, and 30-min post-fentanyl administration. Changes in the Nociception Level Index, heart rate, mean arterial pressure, and bispectral index were compared in response to the tetanic stimuli. Fentanyl plasma concentrations and the Nociception Level Index data were used to elaborate a pharmacokinetic/pharmacodynamic model using a sequential modeling approach in NONMEM®. RESULTS: After the first tetanic stimulus, both the Nociception Level Index and the heart rate increased compared to baseline (8 ± 7 vs. 19 ± 10; mean difference (CI95) -12(-18--6) and 100 ± 10 vs. 102 ± 10; -2(-4--0.1)) and decrease following fentanyl administration (19 ± 10 vs. 8 ± 8; 12 (5-18) and 102 ± 10 vs. 91 ± 11; 11 (7-16)). In subsequent tetanic stimuli, heart rate remained unchanged, while the Nociception Level Index progressively increased within 15 min to values similar to those before fentanyl. An allometric weight-scaled, 3-compartment model best characterized the pharmacokinetic profile of fentanyl. The pharmacokinetic/pharmacodynamic modeling analysis revealed hysteresis between fentanyl plasma concentrations and the Nociception Level Index response, characterized by plasma effect-site equilibration half-time of 1.69 (0.4-2.9) min. The estimated fentanyl C50 was 1.93 (0.73-4.2) ng/mL. CONCLUSION: The Nociception Level Index showed superior capability compared to traditional hemodynamic variables in discriminating different nociception-antinociception levels during varying fentanyl concentrations in children under sevoflurane anesthesia.

The role of collaboration in educating the global pediatric anesthesia workforce.

An estimated 1.7 billion children and adolescents do not have access to safe and affordable surgical care, and the vast majority of these are located in low-middle-income countries (LMICs). Pediatric anesthesia, a specialized field that requires a diverse set of knowledge and skills, has seen various advancements over the years and has become well-established in upper-middle and high-income countries. However, in LMICs, due to a multitude of factors including severe workforce shortages, this has not been the case. Collaborations play a vital role in increasing the capacity of pediatric anesthesiology educators and training the pediatric anesthesia workforce. These efforts directly increase access for children who require surgical intervention. Collaboration models can be operationalized through bidirectional knowledge sharing, training, resource allocation, research and innovation, quality improvement, networking, and advocacy. This article aims to highlight a few of these collaborative efforts. Specifically, the role that the World Federation of Societies of Anaesthesiologists, the Safer Anesthesia from Education program, the Asian Society of Pediatric Anaesthesiologists, Pediatric Anesthesia Training in Africa, the Paediatric Anaesthesia Network New Zealand, the Safe Pediatric Anesthesia Network and two WhatsApp™ groups (global ped anesthesia and the Pediatric Difficult Intubation Collaborative) have played in improving anesthesiology care for children.

Advances in pediatric anesthesia services over the past 10 years in French-speaking sub-Saharan Africa.

INTRODUCTION: To improve and maintain quality and safety in anesthesia, standards have been proposed regarding human resources, facilities and equipment, medications and intravenous fluids, monitoring, and the conduct of anesthesia. Compliance with these standards remains a challenge in French-speaking sub-Saharan Africa (SSA) and results in high morbidity and mortality particularly in children. This aim of this study was to assess the progress made in improving the pediatric anesthesia infrastructures, human resources, education, medications, and equipment in French-speaking SSA over the past 10 years (2013-2022). METHODS: This is a descriptive, multicenter, cross-sectional study with retrospective data collection, conducted from September 1 to November 5, 2023. Comparative data from 2012 to 2022 were collected through an online survey. Descriptive statistics were used to summarize data. RESULTS: Data were obtained from 12 countries out of 14. The number of hospitals providing pediatric surgery and anesthesia rose from 94 in 2012 to 142 in 2022 (+51%). The total number of physician anesthesiologists rose from 293 (0.1 physician anesthesiologists/100 000 inhabitants) in 2012 to 597 (0.2 physician anesthesiologists/100 000 inhabitants) in 2022 (+103.7%). Five (0.006 physician anesthesiologists/100 000 children) had completed a fellowship in pediatric anesthesia and intensive care in 2012, and 15 (0.01 physician anesthesiologists/100 000 children) in 2022 (+200%). Five physician anesthesiologists had an exclusive pediatric anesthesia practice in 2012, whereas they were 32 in 2022 (+540%). There is no specialized training in pediatric anesthesia and intensive care in any of these countries. Halothane was always available in 81.5% of the hospitals in 2012, and in 50.4% of the hospitals in 2022. Sevoflurane was always available in 5% of the hospitals in 2012, and in 36.2% in 2022. Morphine was always available in 32.2% in 2012, whereas it was available in 52.9% of them in 2022. Pediatric pulse oximeter sensors were available in 36% of the hospitals in 2012, and in 63.4% in 2022. Capnography was available in 5.3% of the hospitals in 2012, and in 48% in 2022. CONCLUSION: Progress have been made over the last 10 years in French-speaking SSA to improve infrastructures, human resources, education, medications, and equipment for pediatric anesthesia in French-speaking SSA. However, major efforts must be continued. Standards adapted to the local context should be formulated.

A retrospective observational cohort study of the anesthetic management and outcomes of pediatric patients with Alexander disease undergoing lumbar puncture or magnetic resonance imaging.

BACKGROUND: Alexander disease is a rare, progressive leukodystrophy, which predisposes patients to complications under general anesthesia due to clinical manifestations including developmental delay, seizures, dysphagia, vomiting, and sleep apnea. However, study of anesthetic outcomes is limited. AIMS: Our aim was to describe patient characteristics, anesthetic techniques, and anesthesia-related complications for Alexander disease patients undergoing magnetic resonance imaging and/or lumbar puncture at a quaternary-care children's hospital. METHODS: We performed a retrospective review of anesthetic outcomes in patients with Alexander disease enrolled in a prospective observational study. Included patients had diagnosed Alexander disease and underwent magnetic resonance imaging and/or lumbar puncture at our institution. We excluded anesthetics for other procedures or at outside institutions. Collected data included patient characteristics, anesthetic techniques, medications, and complications under anesthesia and in the subsequent 24 h. We performed descriptive statistics as appropriate. RESULTS: Forty patients undergoing 64 procedures met inclusion criteria. Fifty-six procedures (87.5%) required general anesthesia or monitored anesthesia care (MAC) and eight (12.5%) did not. The general anesthesia/MAC group tended to be younger than nonanesthetized patients (median age 6 years [IQR 3.8; 9] vs. 14.5 years [IQR 12.8; 17.5]). In both groups, dysphagia (78.6% vs. 87.5%, respectively), seizures (62.5% vs. 25%), and recurrent vomiting (17.9% vs. 25%) were frequently reported preprocedure symptoms. Inhalational induction was common (N = 48; 85.7%), and two (3.6%) underwent rapid sequence induction. Serious complications were rare, with no aspiration or seizures. Hypotension resolving with ephedrine occurred in eight cases (14.3%). One patient each (1.8%) experienced postprocedure emergence agitation or vomiting. Fifty-three (94.6%) were ambulatory procedures. No inpatients required escalation in acuity of care. CONCLUSIONS: In this single-center study, patients with Alexander disease did not experience frequent or irreversible complications while undergoing general anesthesia/MAC. Co-morbid symptoms were not increased postanesthesia. Some patients may not require anesthesia to complete short procedures.

The endocrinologist gap: Managing diabetes patients in absence of a specialist.

The treatment of pediatric patients with diabetes is frequently orchestrated within a multidisciplinary framework at tertiary, specialized institutions. In situations where emergent surgery is indicated or when a procedure is scheduled in a facility devoid of an endocrinology service, the onus of managing perioperative glycemic levels may rest with the attending anesthesiologist. The objective of this review is to furnish a comprehensive examination of the anesthetic considerations and perioperative governance of pediatric patients with diabetes. Furthermore, this paper delineates a streamlined protocol for perioperative glycemic control, tailored to both major and minor surgical interventions.

The state of point-of-care ultrasound training in pediatric anesthesia fellowship programs in the United States: A survey assessment.

BACKGROUND: Point-of-care ultrasound is an invaluable bedside tool for anesthesiologists and has been integrated into anesthesiology residency training and board certification in the United States. Little is known about point-of-care ultrasound training practices in pediatric anesthesia fellowship programs. AIMS: To describe the current state of point-of-care ultrasound education in pediatric anesthesia fellowship programs in the United States. METHODS: We conducted a cross-sectional survey study distributed to 60 American Accreditation Council for Graduate Medical Education-accredited pediatric anesthesia fellowship programs. Two programs were in their initial accreditation period and were excluded due to lack of historical data. Program directors or associate program directors were invited to complete this 23-item survey. RESULTS: Thirty-three of fifty-eight programs (57%) completed the survey. Of those, 15 programs (45%) reported having a point-of-care ultrasound curriculum. Programs with ≤3 fellows per year were less likely to have an ultrasound curriculum compared to programs with ≥4 fellows per year (30% programs 0-3 fellows/year vs. 69% programs ≥4 fellows/year, odds ratio 0.19 [95% confidence intervals 0.04-0.87]; p = .03). Program directors and associate program directors rated point-of-care ultrasound training as highly valuable to fellows' education. Barriers to use most commonly included lack of experience (64%), lack of oversight/interpretive guidance (58%), and lack of time (45%). Programs without point-of-care ultrasound training had significantly higher odds of listing lack of ultrasound access as a primary barrier (50% programs without vs. 13% programs with, odds ratio 6.5, [95% confidence intervals 1.3-50]; p = .04). CONCLUSIONS: This observational survey-based study suggests that fewer than half of pediatric anesthesia training programs in the United States offer point-of-care ultrasound education. Additional research is needed to optimize this education and training in pediatric anesthesia fellowship programs.

Evaluation of parental anxiety following three methods of pre-anesthesia counseling: Video, brochure and verbal communication.

BACKGROUND: The purpose of this study is to provide comprehensive and efficient pre-anesthesia counseling (PAC) utilizing audiovisual aids and to examine their effect on parental anxiety. METHODS: For this prospective, controlled study, 174 parents were recruited and randomized into three groups of 58 (Group A: video, Group B: brochure, and Group C: verbal). During pre-anesthesia counseling, the parent was provided with a detailed explanation of preoperative preparation, fasting instructions, transport to the operating room, induction, the emergence of anesthesia, and nursing in the post-anesthesia care unit based on their assigned group. We evaluated parental anxiety using Spielberger's State-Trait Anxiety Inventory before and after the pre-anesthesia counseling. RESULTS: The results of our study show a statistically significant difference in the final mean STAI scores among the three groups (Group A: 34.69 ± 5.31, Group B: 36.34 ± 8.59, and Group C: 43.59 ± 3.39; p < .001). When compared to the brochure and verbal groups, the parents in the video group have the greatest difference in mean baseline and final Spielberger's State-Trait Anxiety Inventory scores (12.207 ± 5.291, p .001). CONCLUSION: The results of our study suggest that pre-anesthesia counseling by video or a brochure before the day of surgery is associated with a higher reduction in parental anxiety when compared to verbal communication.

The effects of dexmedetomidine on intraoperative neurophysiologic monitoring modalities during corrective scoliosis surgery in pediatric patients: A systematic review.

BACKGROUND: During scoliosis surgery, motor evoked potentials (MEP), and somatosensory evoked potentials (SSEP) have been reported to be affected by the use of higher doses of anesthetic agents. Dexmedetomidine, a sympatholytic agent, an alpha-2 receptor agonist, has been used as an adjunctive agent to lower anesthetic dose. However, there is conflicting evidence regarding the effects of dexmedetomidine on the intraoperative neurophysiological monitoring of MEP and SSEP during surgery, particularly among pediatric patients. OBJECTIVES: This systematic review aimed to determine whether, during spinal fusion surgery in pediatric patients with scoliosis, dexmedetomidine alters MEP amplitude or SSEP latency and amplitude and, if so, whether different doses of dexmedetomidine display different effects (PROSPERO registration number CRD42022300562). METHODS: We searched PubMed, Scopus, and Cochrane Library on January 1, 2022 and included randomized controlled trials, observational cohort and case-control studies and case series investigating dexmedetomidine in the population of interest and comparing against a standardized anesthesia regimen without dexmedetomidine or comparing multiple doses of dexmedetomidine. Animal and in vitro studies and conference abstracts were excluded. RESULTS: We found substantial heterogeneity in the risk of bias (per Cochrane-preferred tools) of the included articles (n = 5); results are summarized without meta-analysis. Articles with the lowest risk of bias indicated that dexmedetomidine was associated with MEP loss and that higher doses of dexmedetomidine increased risk. In contrast, articles reporting no association between dexmedetomidine and MEP loss suffered from higher risk of bias, including suspected or confirmed problems with confounding, outcome measurement, participant selection, results reporting, and lack of statistical transparency and power. CONCLUSION: Given the limitations of the studies available in the literature, it would be advisable to conduct rigorous randomized controlled trials with larger sample sizes to assess the effects of dexmedetomidine use of in scoliosis surgery in pediatric patients.

Factors Influencing Willingness to Participate in Clinical Studies in Pediatric Anesthesia (FILIPPA): A vignette-based, structured interview study.

BACKGROUND: Informed consent is a relevant backdrop for conducting clinical trials, particularly those involving children. While several factors are known to influence the willingness to consent to pediatric anesthesia studies, the influence of study design on consenting behavior is unknown. AIMS: To quantify the impact of study complexity on willingness to consent to pediatric anesthesia studies. METHODS: We conducted a vignette-based interview study by presenting three hypothetical studies to 106 parents or legal guardians whose children were scheduled to undergo anesthesia. These studies differed in level of complexity and included an example of a prospective observational study, a randomized controlled trial, and a phase-II-pharmacological study. Primary outcome was the willingness to consent, using a 5-point Likert scale ranging from "absolutely consent" to "absolutely decline". Secondary outcomes were the effects of child-related (such as sex, age, previous anesthesia, research exposure) and proxy-related factors. RESULTS: Response probabilities for "absolute consent" were 90.9% [95% CI 85.3-96.5] for the observational study, 48.6% [95% CI 38.3-58.9] for the randomized controlled trial, and 32.7% [95% CI 23.9-41.6] for the phase-II-pharmacological study. Response probabilities for "absolutely decline" were 1.6% [95% CI 0.3-2.8], 14.4% [95% CI 8.3-20.5], and 24.7% [95% CI 16.6-32.7], respectively. Significant effects were found for previous research exposure (OR = 0.486 [95% CI 0.256-0.923], p = .027), older age (OR = 0.963 [95% CI 0.927-0.999], p = .045) and the gender of the parent or legal guardian, as mothers were less willing to consent (OR = 0.234 [95% CI 0.107-0.512], p < .001). CONCLUSIONS: Willingness to consent decreased with increasing level of study complexity. When conducting more complex studies, greater efforts need to be made to increase the enrollment of pediatric patients.

Error traps in patients with congenital heart disease undergoing noncardiac surgery.

Patients with congenital heart disease are living longer due to improved medical and surgical care. Congenital heart disease encompasses a wide spectrum of defects with varying pathophysiology and unique anesthetic challenges. These patients often present for noncardiac surgery before or after surgical repair and are at increased risk for perioperative morbidity and mortality. Although there is no singular safe anesthetic technique, identifying potential error traps and tailoring perioperative management may help reduce morbidity and mortality. In this article, we discuss five error traps based on the collective experience of the authors. These error traps can occur when providing perioperative care to patients with congenital heart disease for noncardiac surgery and we present potential solutions to help avoid adverse outcomes.

Anesthetic-sparing effect of dexmedetomidine during total intravenous anesthesia for children undergoing dental surgery: A randomized controlled trial.

BACKGROUND: Dexmedetomidine, an α2-adrenergic agonist, reduces propofol and remifentanil requirements when used as an adjunct to total intravenous anesthesia in adults, but studies in a pediatric population are sparse. This study investigates the magnitude of dose-sparing effects of a postinduction dexmedetomidine bolus on propofol and remifentanil requirements during pediatric surgery. METHODS: In this randomized, double-blind, controlled trial, children aged 2-10 years undergoing elective dental surgery were assigned to one of four groups: placebo, 0.25 mcg/kg dexmedetomidine, 0.5 mcg/kg dexmedetomidine, and 1 mcg/kg dexmedetomidine. Maintenance with fixed-ratio propofol and remifentanil total intravenous anesthesia followed a bispectral index (BIS)-guided algorithm designed to maintain a stable depth of anesthesia. The primary outcomes were time-averaged maintenance infusion rates of propofol and remifentanil. Secondary outcomes in the postanesthetic care unit included sedation scores, pain scores, and time to discharge. RESULTS: Data from 67 patients were available for analysis. The median [interquartile range] propofol infusion rate was lower in the 1 mcg/kg dexmedetomidine group (180 [164-185] mcg/kg/min) versus placebo (200 [178-220] mcg/kg/min): percent change -10.0%; 95% CI -2.4 to -19.8; p = 0.013. The remifentanil infusion rate was also lower in the 1 mcg/kg dexmedetomidine group (0.089 [0.080, 0.095] mcg/kg/min) versus placebo (0.103 [0.095, 0.106] mcg/kg/min): percent change, -13.7%; 95% CI -5.47 to -21.0; p = .022. However, neither propofol nor remifentanil infusion rates were significantly different in the 0.25 or 0.5 mcg/kg dexmedetomidine groups. In the postanesthesia care unit, there were no differences in pain or sedation scores, and time to discharge was not significantly prolonged in any dexmedetomidine group. CONCLUSION: Dexmedetomidine 1 mcg/kg reduced the propofol and remifentanil requirements during maintenance of anesthesia in children when administered as a postinduction bolus.

Incidence of complications after nonoperating room anesthesia in children in a low- and middle-income country: A prospective and observational study.

INTRODUCTION: Nonoperating room anesthesia is a growing field of medicine that can have an increased risk of complications, particularly in low- and middle-income countries. AIMS: The aim of this study was to describe the incidence of complications after pediatric nonoperating room anesthesia and investigate its risk factors. METHODS: In this prospective observational study, we included all children aged less than 5 years who were sedated or anesthetized in the radiology setting of a university hospital in a low- and middle-income country. Patients were divided into two groups: complications or no-complications groups. Then, we compared both groups, and univariable and multivariable logistic regression models were used to investigate the main risk factors for complications. RESULTS: We included 256 children, and the incidence of complications was 8.6%. The main predictors of nonoperating room anesthesia-related morbidity were: critically-ill children (aOR = 2.490; 95% CI: 1.55-11.21), predicted difficult airway (aOR = 5.704; 95% CI: 1.017-31.98), and organization insufficiencies (aOR = 52.6; 95% CI:4.55-613). The preanesthetic consultation few days before NORA protected against complications (aOR = 0.263; 95%CI: 0.080-0.867). CONCLUSIONS: The incidence of complications during NORA among children in our radiology setting remains high. Investigating predictors for morbidity allowed high-risk patient selection, which allowed taking precautions. Several improvement measures were taken to address the organization's insufficiencies.
