Diagnostic Bedside Ultrasound Program Development in Pediatric Critical Care Medicine: Results of a National Survey

National survey of diagnostic point of care ultrasound practices and program development in academic neonatal-perinatal medicine centers

OBJECTIVE

To assess diagnostic point of care ultrasound (POCUS) use, presence of programmatic infrastructural elements, and barriers to implementation across neonatal perinatal medicine (NPM) programs in the United States.

STUDY DESIGN

Cross-sectional study. An online survey was distributed to leaders in education or POCUS at ACGME-accredited NPM fellowship programs. National trends were outlined using descriptive statistics and compared by program size.

RESULT

79 of 99 (80%) NPM programs responded. Diagnostic POCUS was available at 71% (n = 56) of sites that responded. Key infrastructural elements were present at <45% of sites, with fellow training being the exception (71%). Many barriers to diagnostic POCUS program implementation were identified and they differed by program size.

CONCLUSION

Diagnostic POCUS is being increasingly adopted despite underdeveloped programmatic infrastructure. Identified barriers suggest a need for collaborative efforts to support the necessary infrastructural elements, and differences by program size suggest a need for tailored approaches for successful integration.

POCUS in the PICU: A Narrative Review of Evidence-Based Bedside Ultrasound Techniques Ready for Prime-Time in Pediatric Critical Care

Point-of-care ultrasound (POCUS) is an accessible technology that can identify and treat life-threatening pathology in real time without exposing children to ionizing radiation. We aim to review current evidence supporting the use of POCUS by pediatric intensivists with novice-level experience with bedside ultrasound. Current evidence supports the universal adoption of POCUS-guided internal jugular venous catheter placement and arterial line placement by pediatric critical care physicians. Focused cardiac ultrasound performed by PICU physicians who have completed appropriate training with quality assurance measures in place can identify life-threatening cardiac pathology in most children and important physiological changes in children with septic shock. POCUS of the lungs, pleural space, and diaphragm have great potential to provide valuable information at the bedside after validation of these techniques for use in the PICU with additional research. Based on currently available evidence, a generalizable and attainable POCUS educational platform for pediatric intensivists should include training in vascular access techniques and focused cardiac examination. A POCUS educational program should strive to establish credentialing and quality assurance programs that can be expanded when additional research validates the adoption of additional POCUS techniques by pediatric intensive care physicians.

The Use of Point-of-Care Ultrasound in Pediatric Emergency Departments and Intensive Care Units: A Descriptive Study From Turkey

OBJECTIVES

The aim was to evaluate the current status of point-of-care ultrasound (POCUS), perceptions, education, training, and barriers to using POCUS in pediatric emergency departments (PEDs) and pediatric intensive care units (PICUs) in Turkey.

METHODS

A descriptive, multicenter, cross-sectional study through an online survey was developed using the REDCap online platform. The survey was distributed through the Turkish Society of Pediatric Emergency and Intensive Care e-mail group. Each survey was answered only once by each PED/PICU and by the clinical chief of the department.

RESULTS

A total of 19 PEDs and 26 PICUs responded to the survey. Among them, 84.2% of PEDs and 100% of PICUs reported the clinical use of POCUS. For diagnostic applications, the most common areas for PEDs and PICUs were thoracic (93.7%/100%) and cardiovascular (62.5%/65.4%) assessment, and in the procedural use of POCUS, the most frequent applications were those for vascular access (75.0%/92.3%) and thoracentesis (31.2%/65.4%). The most commonly reported clinical benefits were rapid diagnosis, rapid treatment, and decreased complications during procedural applications for PEDs and PICUs. Evaluating the barriers to POCUS use in PEDs and PICUs, the most common reasons for insufficient use were the lack of ultrasound machines and/or equipment, a shortage of manpower, lack of awareness, and lack of training. For PEDs (68.4%) and for PICUs (84.6%), participants agreed that POCUS training should be mandatory during fellowship programs.

CONCLUSIONS

Most participants were aware of the need for POCUS. However, lack of education, equipment, manpower, and infrastructure still emerged as barriers to the use of POCUS. To further promote POCUS use, it would be helpful to improve accessibility by ensuring sufficient numbers of ultrasound devices together with sufficient numbers of appointed physicians and by expanding POCUS education in PEDs and PICUs.

Evolution and Impact of a Diagnostic Point-of-Care Ultrasound Program in a PICU

OBJECTIVES

To evaluate the impact of point-of-care ultrasound (POCUS) use on clinicians within a PICU and to assess infrastructural elements of our POCUS program development.

DESIGN

Retrospective observational study.

SETTING

Large academic, noncardiac PICU in the United States.

SUBJECTS

Patients in a PICU who had diagnostic POCUS performed.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Between January 1, 2017, and December 31, 2022, 7201 diagnostic POCUS studies were ordered; 1930 (26.8%) had a quality assurance (QA) record generated in an independent POCUS QA database. The cardiac domain was most frequently imaged (81.0% of ordered studies, 81.2% of reviewed studies). POCUS images changed clinician understanding of pathophysiology in 563 of 1930 cases (29.2%); when this occurred, management was changed in 318 of 563 cases (56.5%). Cardiac POCUS studies altered clinician suspected pathophysiology in 30.1% of cases (472/1568), compared with 21.5% (91/362) in noncardiac studies ( p = 0.06). Among cases where POCUS changed clinician understanding, management changed more often following cardiac than noncardiac POCUS ( p = 0.02). Clinicians identified a need for cardiology consultation or complete echocardiograms in 294 of 1568 cardiac POCUS studies (18.8%). Orders for POCUS imaging increased by 94.9%, and revenue increased by 159.4%, from initial to final study year. QA database use by both clinicians and reviewers decreased annually as QA processes evolved in the setting of technologic growth and unit expansion.

CONCLUSIONS

Diagnostic POCUS imaging in the PICU frequently yields information that alters diagnosis and changes management. As PICU POCUS use increased, QA processes evolved resulting in decreased use of our initial QA database. Modifications to QA processes are likely necessary as clinical contexts change over time.

Management Changes After Echocardiography Are Associated With Improved Outcomes in Critically Ill Children

OBJECTIVES

To evaluate management changes and outcomes in critically ill children after formal echocardiography.

DESIGN

Retrospective cohort study between January 1, 2011, and December 31, 2020.

SETTING

Tertiary care children's hospital.

PATIENTS

Patients from 1 to 18 years who had formal echocardiography within 72 hours of ICU admission and who were intubated and on vasoactive infusions at the time of the study. Patients were stratified into two cardiac function groups: 1) near-normal cardiac function and 2) depressed cardiac function.

METHODS

Clinical variables were abstracted from the electronic medical record and placed in time sequence relative to echocardiography. Vasoactive and fluid management strategies in place before echocardiography were associated with markers of tissue perfusion and volume overload. Management changes after echocardiography were characterized and associated with outcomes.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Among patients eventually found to have depressed cardiac function, the use of vasoconstrictors was associated with worse lactate clearance and oxygen extraction ratio. Use of vasoconstrictors in this cohort was also associated with a more liberal fluid management strategy, evidence of increased lung water, and a worse Sp o2 /F io2 . An echocardiogram demonstrated depressed cardiac function was likely to be followed by management changes that favored inotropes and more conservative fluid administration. Patients with depressed cardiac function who were switched to inotropes were more likely to be extubated and to wean off vasoactive support compared with those patients who remained on vasoconstrictors.

CONCLUSIONS

Among patients with depressed cardiac function, alterations in management strategy after echocardiography are associated with shortened duration of intensive care interventions.

Pediatric ultrasound practice in Italy: an exploratory survey

BACKGROUND

The aim of this exploratory survey is to describe the current state of US (ultrasound) technique across different pediatric settings nationwide.

METHODS

A questionnaire was emailed to all members of the Italian Society of Pediatrics, including pediatric residents. The survey was open from December 2021 to March 2022.

RESULTS

There were 1098 respondents. Seven hundred and seven pediatricians (84.1%) reported any use of US, while 51 (44.3%) residents denied it. The majority of participants (n = 956, 87.1%) reported to have a US machine available within the department, mostly cart-based (n = 516, 66.9%) and provided from 1 to 5 years prior to the survey (n = 330, 42.8%). Lung and neonatal cerebral regions were the most frequently scanned (n = 289, 18.7% and n = 218, 14.1%, respectively). The suspicion of pneumonia or respiratory distress represented the main reasons for performing US in emergency room (n = 390, 78% and n = 330, 66%, respectively). The majority of family pediatricians reported to scan lung and kidney/urinary tract regions (n = 30, 16.9%, and n = 23,12.9%, respectively). Regarding US training, the majority of respondents (n = 358, 34.6%) declared an experience-based education, with a deficient certification enabling the use of US in 71.6% (n = 552) of cases. The most common barriers included the lack of a well-defined training program (n = 627, 57.1%), unavailability of the US machine (n = 196, 17.9%) and legal responsibility concern (n = 175, 15.9%).

CONCLUSIONS

Despite the growing interest on pediatric US nationally, significant barriers still limit widespread adoption. These obstacles may be addressed through the dissemination of a specific US education plan and providing additional resources.

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.

Point-of-care ultrasound in pediatric anesthesiology: considerations for training and credentialing

PURPOSE OF REVIEW

To discuss considerations surrounding the use of point-of-care ultrasound (POCUS) in pediatric anesthesiology.

RECENT FINDINGS

POCUS is an indispensable tool in various medical specialties, including pediatric anesthesiology. Credentialing for POCUS should be considered to ensure that practitioners are able to acquire images, interpret them correctly, and use ultrasound to guide procedures safely and effectively. In the absence of formal guidelines for anesthesiology, current practice and oversight varies by institution. In this review, we will explore the significance of POCUS in pediatric anesthesiology, discuss credentialing, and compare the specific requirements and challenges currently associated with using POCUS in pediatric anesthesia.

SUMMARY

Point-of-care ultrasound is being utilized by the pediatric anesthesiologist and has the potential to improve patient assessment, procedure guidance, and decision-making. Guidelines increase standardization and quality assurance procedures help maintain high-quality data. Credentialing standards for POCUS in pediatric anesthesiology are essential to ensure that practitioners have the necessary skills and knowledge to use this technology effectively and safely. Currently, there are no national pediatric POCUS guidelines to base credentialing processes on for pediatric anesthesia practices. Further work directed at establishing pediatric-specific curriculum goals and competency standards are needed to train current and future pediatric anesthesia providers and increase overall acceptance of POCUS use.

Pediatric Profound Dengue Shock Syndrome and Use of Point-of-Care Ultrasound During Mechanical Ventilation to Guide Treatment: Single-Center Retrospective Study, 2013-2021

OBJECTIVES

Profound dengue shock syndrome (DSS) complicated by severe respiratory failure necessitating mechanical ventilation (MV) accounts for high case fatality rates among PICU-admitted patients. A major challenge to management is the assessment of intravascular volume, which can be hampered by severe plasma leakage and the use of MV.

DESIGN

Retrospective cohort, from 2013 to 2021.

PATIENTS

Sixty-seven children with profound DSS supported by MV, some of whom underwent bedside point-of-care ultrasound (POCUS) for assessment and monitoring of hemodynamics and fluid administration.

SETTING

PICU of the tertiary Children's Hospital No. 2 in Vietnam.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We analyzed data clinical and laboratory data during PICU stay. In particular, during use of MV (i.e., at times 0-, 6-, and 24-hr after commencement) and fluid resuscitation. The primary study outcome was 28-day in-hospital mortality, and the secondary outcomes were associations with changes in hemodynamics, blood lactate, and vasoactive-inotrope score (VIS). Patients had a median age of 7 years (interquartile range, 4-9). Use of POCUS during fluid management (39/67), as opposed to not using (28/67), was associated with lower mortality (6/39 [15%] vs. 18/28 [64%]; difference 49 % [95% CI, 28-70%], p < 0.001). Use of POCUS was associated with lower odds of death (adjusted odds ratio 0.17 [95% CI, 0.04-0.76], p = 0.02). The utilization of POCUS, versus not, was associated with greater use of resuscitation fluid, and reductions in VIS and pediatric logistic organ dysfunction (PELOD-2) score at 24 hours after MV and PICU discharge.

CONCLUSIONS

In our experience of pediatric patients with profound DSS and undergoing MV (2013-2021), POCUS use was associated with lower odds of death, a higher volume of resuscitation fluid, and improvements in the blood lactate levels, VIS, and PELOD-2 score.

Point-of-care ultrasound as a diagnostic tool in respiratory assessment in awake paediatric patients: a comparative study

BACKGROUND

Chest X-ray (CXR) has typically been the main investigation in children with suspected respiratory pathology. Recent advances in lung point-of-care ultrasound (POCUS) have shown the potential for it to be comparative, if not better, than CXR. The objective of this study was to compare CXR with lung POCUS in children with respiratory illness in a ward-based setting at a paediatric teaching hospital.

METHODS

Any child <18 years of age presenting to Southampton Children's Hospital requiring a CXR for clinical reasons also had lung POCUS performed. CXR was reported by a consultant paediatric radiologist and lung POCUS was reviewed retrospectively by a blinded POCUS clinician, with only the clinical information provided on the CXR request. Comparisons were made between the CXR and lung POCUS findings.

RESULTS

100 paired lung POCUS and CXR were included in the study. 30% of lung POCUS were normal with 97% of these having a normal CXR. 70% of cases had POCUS abnormalities with 96% of POCUS cases identifying comparative lung pathology. Lung POCUS therefore had a sensitivity of 98.51% and a specificity of 87.9% with a diagnostic accuracy of 95% when compared with the CXR report.

CONCLUSIONS

Lung POCUS has excellent diagnostic accuracy. The diagnosis of normal lung on POCUS when performed by a trained practitioner can reliably reduce the need for a CXR, thus reducing CXR use and radiation exposure in children. An abnormal lung POCUS could then either give the diagnosis or lead to a CXR with the expectation of clinically relevant findings.

Performance of Tools and Measures to Predict Fluid Responsiveness in Pediatric Shock and Critical Illness: A Systematic Review and Meta-Analysis

OBJECTIVES

In this systematic review and meta-analysis we asked: Do predictors of fluid responsiveness in children perform comparably: 1) in the PICU as in non-PICU settings? 2) in shock states compared with nonshock states? Additionally, 3) is there an association between preload responsiveness and clinical response?

DATA SOURCES

Ovid Medline, PubMed, and Embase databases were searched from inception through May 2022.

STUDY SELECTION

Included studies reported physiological response to IV fluid administration in humans less than 18 years. Only studies reporting an area under the receiver operating characteristic curve (AUROC) were included for descriptive analysis. Only studies for which a se could be estimated were included for meta-analysis.

DATA EXTRACTION

Title, abstract, full text screening, and extraction were completed by two authors (S.B.W., J.M.W.). Variables extracted included predictors ("tools") and outcome measures ("reference tests") of fluid responsiveness, demographic, and clinical variables.

DATA SYNTHESIS

We identified 62 articles containing 204 AUROCs for 55 tools, primarily describing mechanically ventilated children in an operating room or PICU. Meta-analysis across all tools showed poor predictive performance (AUROC, 0.66; 95% CI, 0.63-0.69), although individual performance varied greatly (range, 0.49-0.87). After controlling for PICU setting and shock state, PICU setting was associated with decreased predictive performance (coefficient, -0.56; p = 0.0007), while shock state was associated with increased performance (0.54; p = 0.0006). Effect of PICU setting and shock state on each tool was not statistically significant but analysis was limited by sample size. The association between preload responsiveness and clinical response was rarely studied but results did not suggest an association. Ultrasound measurements were prone to inherent test review and incorporation biases.

CONCLUSIONS

We suggest three opportunities for further research in fluid responsiveness in children: 1) assessing predictive performance of tools during resuscitation in shock states; 2) separating predictive tool from reference test when using ultrasound techniques; and 3) targeting decreasing time in a shock state, rather than just increase in preload.

A Scoping Review of Ultrasonographic Techniques in the Evaluation of the Pediatric Airway

Point-of-care ultrasound is making rapid advancements in pediatrics, and ultrasonographic assessment of the airway is being employed in many specialties such as the pediatric, cardiac, and neonatal intensive care units, emergency department, pulmonary clinic, and the perioperative setting. This scoping review provides a technical description of image acquisition and interpretation, accompanying ultrasound images of the hallmark airway applications in pediatrics, and supporting evidence when available. We describe and illustrate ultrasound-determined endotracheal tube (ETT) sizing, ETT placement and depth confirmation, vocal fold assessment, prediction of post-extubation stridor, difficult laryngoscopy prediction, and cricothyrotomy guidance. This review aims to provide the descriptions and images necessary to learn and apply these skills at the point of care in the pediatric patient.

Translating Guidelines into Practical Practice: Point-of-Care Ultrasound for Pediatric Critical Care Clinicians

Point-of-care ultrasound (POCUS) is now transitioning from an emerging technology to a standard of care for critically ill children. POCUS can provide immediate answers to clinical questions impacting management and outcomes within this fragile population. Recently published international guidelines specific to POCUS use in neonatal and pediatric critical care populations now complement previous Society of Critical Care Medicine guidelines. The authors review consensus statements within guidelines, identify important limitations to statements, and provide considerations for the successful implementation of POCUS in the pediatric critical care setting.

Contemporary Use of Ultrasonography in Acute Care Pediatrics

Use of ultrasonography by clinicians at the point of care has expanded widely and rapidly. Pediatric acute care providers now leverage this valuable tool to guide procedures, diagnose pathophysiologic processes, and inform time-sensitive decisions in sick and unstable children. However, the deployment of any new technology must be packaged with training, protocols, and safeguards to optimize safety for patients, providers, and institutions. As ultrasonography is increasingly incorporated into residency, fellowship, and even medical student curricula, it is important that educators and trainees are aware of the diversity of its clinical applications. This article aims to review the current state of point-of-care ultrasonography in acute care pediatrics, with an emphasis on the literature supporting the use of this important clinical tool.

Recommendations for Cardiac Point-of-Care Ultrasound in Children: A Report from the American Society of Echocardiography

Cardiac point-of-care ultrasound has the potential to improve patient care, but its application to children requires consideration of anatomic and physiologic differences from adult populations, and corresponding technical aspects of performance. This document is the product of an American Society of Echocardiography task force composed of representatives from pediatric cardiology, pediatric critical care medicine, pediatric emergency medicine, pediatric anesthesiology, and others, assembled to provide expert guidance. This diverse group aimed to identify common considerations across disciplines to guide evolution of indications, and to identify common requirements and infrastructure necessary for optimal performance, training, and quality assurance in the practice of cardiac point-of-care ultrasound in children. The recommendations presented are intended to facilitate collaboration among subspecialties and with pediatric echocardiography laboratories by identifying key considerations regarding (1) indications, (2) imaging recommendations, (3) training and competency assessment, and (4) quality assurance.

A point-of-care ultrasound education curriculum for pediatric critical care medicine

BACKGROUND

Diagnostic and procedural point-of-care ultrasound (POCUS) change patient management with the potential to improve outcomes. Pediatric critical care medicine trainees have limited access to education and training opportunities in diagnostic POCUS in the pediatric ICU. A dearth of published pediatric ICU curricular resources restricts these educational opportunities.

METHODS

A 7-week longitudinal curriculum including lectures, practical skills sessions, and knowledge assessment covering core modules including (1) machine operation, (2) vascular access, (3) non-vascular procedures, (4) cardiac imaging, (5) hemodynamic assessment, (6) pulmonary imaging, and (7) abdominal imaging, was disseminated to pediatric critical care trainees and faculty at a single tertiary care pediatric hospital.

RESULTS

The knowledge of trainees and participating faculty in procedural and diagnostic POCUS improved after implementing the curriculum. Pre-test scores mean and standard deviation (59.30% ± 14.15%) improved significantly (75.60% ± 9.43%) for all learners (p < 0.001). The overall self-reported comfort in diagnostic and procedural ultrasound improved for all learners. 100% of the learners reported utilizing diagnostic POCUS in their clinical practice four months after disseminating the curriculum.

DISCUSSION

We describe a single center's approach to POCUS education with improvement in knowledge, self-reported comfort, and attitudes towards procedural and diagnostic POCUS. The curricular resources for adaptation in a similar educational context are provided.

Point-of-care ultrasound in pediatric nephrology

Point-of-care ultrasound (POCUS) has evolved in recent years in clinical practice, helping in early bedside diagnosis of important etiologies. Many medical schools and training programs are integrating POCUS into their curriculum. Especially with the technological advances of newer handheld ultrasound devices, POCUS has now become a component adjunct to clinical examination, in the clinic and bedside in critical care units. The diagnostic utility of POCUS lies both in early identification of critical kidney disease, and also extra-renal pathologies from a focused cardiac ultrasound, lung ultrasound, and integrated fluid assessment. There is a need to incorporate POCUS in training in pediatric nephrology and establish competency standard criteria. This review shall cover how POCUS helps in enhancing patient care in pediatric kidney disorders and critical children, and the recent advances.

Point-of-care ultrasound training for residents in anaesthesia and critical care: results of a national survey comparing residents and training program directors' perspectives

BACKGROUND

Point-of-care ultrasound (POCUS) has become an essential tool for anaesthesia and critical care physicians and dedicated training is mandatory. This survey describes the current state of Italian residency training programs through the comparison of residents' and directors' perspective.

METHODS

Observational prospective cross-sectional study: 12-question national e-survey sent to Italian directors of anaesthesia and critical care residency programs (N = 40) and residents (N = 3000). Questions focused on POCUS teaching (vascular access, transthoracic echocardiography, focused assessment for trauma, transcranial Doppler, regional anaesthesia, lung and diaphragm ultrasound), organization (dedicated hours, teaching tools, mentors), perceived adequacy/importance of the training and limiting factors.

RESULTS

Five hundred seventy-one residents and 22 directors completed the survey. Bedside teaching (59.4-93.2%) and classroom lessons (29.7-54.4%) were the most frequent teaching tools. Directors reported higher participation in research projects (p < 0.05 for all techniques but focused assessment for trauma) and simulation (p < 0.05 for all techniques but transthoracic echocardiography). Use of online teaching was limited (< 10%); however, 87.4% of residents used additional web-based tools. Consultants were the most frequent mentors, with different perspectives between residents (72.0%) and directors (95.5%; p = 0.013). Residents reported self-training more frequently (48.5 vs. 9.1%; p < 0.001). Evaluation was mainly performed at the bedside; a certification was not available in most cases (< 10%). Most residents perceived POCUS techniques as extremely important. Residents underestimated the relevance given by directors to ultrasound skills in their evaluation and the minimal number of exams required to achieve basic competency. Overall, the training was considered adequate for vascular access only (62.2%). Directors mainly agreed on the need of ultrasound teaching improvement in all fields. Main limitations were the absence of a standardized curriculum for residents and limited mentors' time/expertise for directors.

CONCLUSION

POCUS education is present in Italian anaesthesia and critical care residency programs, although with potential for improvement. Significant discrepancies between residents' and directors' perspectives were identified.

The Inter-Rater Reliability of Pediatric Point-of-Care Lung Ultrasound Interpretation in Children With Acute Respiratory Failure

OBJECTIVES

Use of point-of-care lung ultrasound (POC-LUS) has increased significantly in pediatrics yet it remains under-studied in the pediatric intensive care unit (PICU). No studies explicitly evaluate the reliability of POC-LUS artifact interpretation among critically ill children with acute respiratory failure (ARF) in the PICU. We thus designed this study to determine the inter-rater reliability of POC-LUS interpretation in pediatric ARF among pediatric intensivists trained in POC-LUS and an expert intensivist.

METHODS

We compared the interpretation of lung sliding, pleural line characteristics, ultrasound artifacts, and POC-LUS diagnoses among pediatric intensivists and an expert intensivist in a cohort of children admitted to the PICU for ARF. Kappa statistics (k) adjusted for maximum attainable agreement (k/k_max ) were used to quantify chance-correct agreement between the pediatric intensivist and expert physician.

RESULTS

We enrolled 88 patients, evaluating 3 zones per hemithorax (anterior, lateral, and posterior) for lung sliding, pleural line characteristics, ultrasound artifacts, and diagnosis. There was moderate agreement between the PICU intensivist and expert-derived diagnoses with 56% observed agreement (k/k_max  = 0.46, 95% confidence interval [CI] 0.31-0.65). Agreement in identification of lung sliding (k = 0.19, 95% CI -0.17 to 0.56) and pleural line characteristics (k = 0.24, 95% CI 0.08-0.40) was slight and fair, respectively, while agreement in the interpretation of ultrasound artifacts ranged from moderate to substantial.

CONCLUSIONS

Evidence supporting the evaluation of neonatal and adult patients with POC-LUS should not be extrapolated to critically ill pediatric patients. This study adds to the evidence supporting use of POC-LUS in the PICU by demonstrating moderate agreement between PICU intensivist and expert-derived POC-LUS diagnoses.

Lung Ultrasound Artifact Findings in Pediatric Patients Admitted to the Intensive Care Unit for Acute Respiratory Failure

PURPOSE

To describe point-of-care lung ultrasound (POC-LUS) artifact findings in children admitted to the pediatric intensive care unit (PICU) for acute respiratory failure (ARF).

METHODS

This is a secondary analysis of a prospective observational study completed in a 21-bed PICU. Children > 37 weeks gestational age and ≤ 18 years were enrolled from December 2018 to February 2020. POC-LUS was completed and interpreted by separate physicians blinded to all clinical information. POC-LUS was evaluated for the presence of lung sliding, pleural line characteristics, ultrasound artifacts, and the ultrasound diagnosis.

RESULTS

Eighty-seven subjects were included. A-lines were the most frequent artifact, occurring in 58% of lung zones (163/281) in those with bronchiolitis, 39% of lung zones (64/164) in those with pneumonia, and 81% of lung zones (48/59) in those with status asthmaticus. Sub-pleural consolidation was second most common, occurring in 28% (80/281), 30% (50/164), and 12% (7/59) of those with bronchiolitis, pneumonia, and status asthmaticus, respectively. The pattern a priori defined as bronchiolitis, pneumonia, and status asthmaticus was demonstrated in 31% (15/48), 10% (3/29), and 40% (4/10) of subjects with bronchiolitis, pneumonia, and status asthmaticus, respectively.

CONCLUSION

We found significant heterogeneity and overlap of POC-LUS artifacts across the most common etiologies of ARF in children admitted to the PICU. We have described the POC-LUS artifact findings in pediatric ARF to support clinicians using POC-LUS and to guide future pediatric POC-LUS studies. Determining the optimal role of POC-LUS as an adjunct in the care of pediatric patients requires further study.

Point-of-Care Ultrasound in the Pediatric Intensive Care Unit

Ultrasonography has been widely used in medicine for decades but often by specific users such as cardiologists, obstetricians, and radiologists. In the last several years, the use of this imaging modality has moved to the bedside, with clinicians performing and interpreting focused point of care ultrasonography to aid in immediate assessment and management of their patients. The growth of point of care ultrasonography has been facilitated by advancement in ultrasound-related technology and emerging studies and protocols demonstrating its utility in clinical practice. However, considerable challenges remain before this modality can be adopted across the spectrum of disciplines, primarily as it relates to training, competency, and standardization of usage. This review outlines the history, current state, challenges and the future direction of point of care ultrasonography specifically in the field of pediatric critical care medicine.

Implementation of a Longitudinal Critical Care Fellowship Ultrasound Curriculum

Background

The use of point-of-care ultrasound as a diagnostic and interventional tool is rapidly becoming standard of care in critical care medicine; a standardized training curriculum is needed to ensure provider proficiency.

Objective

This study aimed to describe a longitudinal critical care ultrasound (CCUS) curriculum in a pulmonary critical care medicine (PCCM) fellowship training program. It evaluated the curriculum’s impact on fellows’ knowledge, skills, and self-reported confidence and retention of these attributes.

Methods

We conducted a prospective observational study of a longitudinal CCUS training program within a single PCCM fellowship training program. Knowledge, skills, and confidence of 22 fellows were assessed at baseline; after initial training; and at 6, 12, and 18 months in five domains (ultrasound basics, vascular, lung/pleural, abdomen, and cardiac). We quantified changes in CCUS knowledge, confidence, and skills by fellowship class and assessed for longitudinal retention of these three attributes. The difference in scores between new first-year fellows undergoing formal training and second-year fellows with previous informal training was compared at matched time points.

Results

After the initial formal training, there was a significant increase in knowledge, skills, and confidence scores, which were maintained or continued to increase up to 18 months. Fellows with 1 year of formal training also had a higher level of knowledge and skills than fellows with 1 year of informal training, although they had similar levels of self-reported confidence in their skills.

Conclusion

A formal, longitudinal CCUS curriculum implemented in a PCCM fellowship program improves trainees’ knowledge and skills in various ultrasound domains in addition to their confidence in using ultrasound for patient care. A longitudinal curriculum results in retention of all three attributes and appeared to be more effective than an informal training program based on teaching during rounds, but this needs to be replicated in a larger cohort.

Establishing a risk assessment framework for point-of-care ultrasound

Point-of-care ultrasound (POCUS) refers to the use of portable ultrasound (US) applications at the bedside, performed directly by the treating physician, for either diagnostic or procedure guidance purposes. It is being rapidly adopted by traditionally non-imaging medical specialties across the globe. Recent international evidence-based guidelines on POCUS for critically ill neonates and children were issued by the POCUS Working Group of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC). Currently there are no standardized national or international guidelines for its implementation into clinical practice or even the training curriculum to monitor quality assurance. Further, there are no definitions or methods of POCUS competency measurement across its varied clinical applications.

CONCLUSION

The Hippocratic Oath suggests medical providers do no harm to their patients. In our continued quest to uphold this value, providers seeking solutions to clinical problems must often weigh the benefit of an intervention with the risk of harm to the patient. Technologies to guide diagnosis and medical management present unique considerations when assessing possible risk to the patient. Frequently risk extends beyond the patient and impacts providers and the institutions in which they practice. POCUS is an emerging technology increasingly incorporated in the care of children across varied clinical specialties. Concerns have been raised by clinical colleagues and regulatory agencies regarding appropriate POCUS use and oversight. We present a framework for assessing the risk of POCUS use in pediatrics and suggest methods of mitigating risk to optimize safety and outcomes for patients, providers, and institutions.

WHAT IS KNOWN

• The use POCUS by traditionally non-imaging pediatric specialty physicians for both diagnostic and procedural guidance is rapidly increasing. • Although there are international guidelines for its indications, currently there is no standardized guidance on its implementation in clinical practice.

WHAT IS NEW

• Although standards for pediatric specialty-specific POCUS curriculum and training to competency have not been defined, POCUS is likely to be most successfully incorporated in clinical care when programmatic infrastructural elements are present. • Risk assessment is a forward-thinking process and requires an imprecise calculus that integrates considerations of the technology, the provider, and the context in which medical care is delivered. Medicolegal considerations vary across countries and frequently change, requiring providers and institutions to understand local regulatory requirements and legal frameworks to mitigate the potential risks of POCUS.

Point-of-Care Ultrasound Training in Pediatric Residency: A National Needs Assessment

BACKGROUND AND OBJECTIVES

As point-of-care ultrasound (POCUS) evolves into a standard tool for the care of children, pediatric residency programs need to develop POCUS training programs. Few POCUS training resources exist for pediatric residents, and little is known about POCUS training in pediatric residencies. We aim to describe pediatric residency leadership perspectives regarding the value of POCUS and to elucidate the current state of POCUS training in pediatric residency programs.

METHODS

A group of pediatric educators and POCUS experts developed a novel survey followed by cognitive interviews to establish response-process validity. The survey was administered electronically to pediatric residency associate program directors between December 2019 and April 2020. Program characteristics, including region, setting, and size, were used to perform poststratification for analyses. We performed comparative analyses using program and respondent characteristics.

RESULTS

We achieved a 30% (58 of 196) survey response rate. Although only a minority of respondents (26%) used POCUS in clinical practice, a majority (56%) indicated that all pediatric residents should be trained in POCUS. A majority of respondents also considered 8 of 10 POCUS applications important for pediatric residents. Only 37% of programs reported any POCUS training for residents, primarily informal bedside education. Most respondents (94%) cited a lack of qualified instructors as a barrier to POCUS training.

CONCLUSIONS

Most pediatric residency programs do not provide residents with POCUS training despite its perceived value and importance. Numerous POCUS applications are considered important for pediatric residents to learn. Future curricular and faculty development efforts should address the lack of qualified POCUS instructors.

The Utility of Point-of-Care Ultrasound in the Pediatric Intensive Care Unit

Objectives: Point of care ultrasound (POCUS) in adult critical care environments has become the standard of care in many hospitals. A robust literature shows its benefits for both diagnosis and delivery of care. The utility of POCUS in the pediatric intensive care unit (PICU), however, is understudied. This study describes in a series of PICU patients the clinical indications, protocols, findings and impact of pediatric POCUS on clinical management. Design: Retrospective analysis of 200 consecutive POCUS scans performed by a PICU physician. Patients: Pediatric critical care patients who required POCUS scans over a 15-month period. Setting: The pediatric and cardiac ICUs at a tertiary pediatric care center. Interventions: Performance of a POCUS scan by a pediatric critical care attending with advanced training in ultrasonography. Measurement and Main Results: A total of 200 POCUS scans comprised of one or more protocols (lung and pleura, cardiac, abdominal, or vascular diagnostic protocols) were performed on 155 patients over a 15-month period. The protocols used for each scan reflected the clinical question to be answered. These 200 scans included 133 thoracic protocols, 110 cardiac protocols, 77 abdominal protocols, and 4 vascular protocols. In this series, 42% of scans identified pathology that required a change in therapy, 26% confirmed pathology consistent with the ongoing plans for new therapy, and 32% identified pathology that did not result in initiation of a new therapy. Conclusions: POCUS performed by a trained pediatric intensivist provided useful clinical information to guide patient management.

A Call to Action for the Pediatric Critical Care Community

Healthcare regulatory bodies have escalated concerns regarding the use of point-of-care ultrasound by nonradiology and noncardiology physicians. A recently published PCCMPerspective identified that data do not support many of these concerns and addressed common misconceptions associated with point-of-care ultrasound use in the critical care setting. Indeed, the global point-of-care ultrasound community and specifically the pediatric critical care community have the opportunity to be leaders in demonstrating how to translate new skills and technologies to the bedside in a safe and effective manner. We seek to extend the conversation and propose next steps in supporting integration of point-of-care ultrasound in pediatric critical care practice.

Regulating Critical Care Ultrasound, It Is All in the Interpretation

Point-of-care ultrasound (POCUS) use is rapidly expanding as a practice in adult and pediatric critical care environments. In January 2020, the Joint Commission endorsed a statement from the Emergency Care Research Institute citing point-of-care ultrasound as a potential hazard to patients for reasons related to training and skill verification, oversight of use, and recordkeeping and accountability mechanisms for clinical use; however, no evidence was presented to support these concerns. Existing data on point-of-care ultrasound practices in pediatric critical care settings verify that point-of-care ultrasound use continues to increase, and contrary to the concerns raised, resources are becoming increasingly available for point-of-care ultrasound use. Many institutions have recognized a successful approach to addressing these concerns that can be achieved through multispecialty collaborations.

An email-based survey of practice regarding hemodynamic monitoring and management in children with septic shock in China

BACKGROUND

Understanding current hemodynamic monitoring (HM) practice patterns is essential to determine education and training strategies in China. The survey was to describe the practice of HM and management in children with septic shock in China.

METHODS

We conducted an Email-based survey of members of sub-association of pediatric intensive care physicians. The questionnaire consisted of 22 questions and gathered the following information: (I) general information on the hospitals, respective ICUs and participants, (II) the availability of technical equipment and parameters of HM and (III) management simulation of septic shock in three clinical case vignettes.

RESULTS

Surveys were received from 68 institutions (87.2%) and 368 questionnaires (response-rate 45.1%) were included. Basic HM (93-100%) were reported as the most utilized parameters, followed by advanced HM which included central venous pressure (CVP) (56.0%), cardiac output (53.5%), and central venous oxygen saturation (36.7%), 61.1% (225/368) of respondents stated the utilization of non-invasive HM equipment. The factors such as ICU specialist training center (P=0.003) and more than 30 cases of septic shock per year (P=0.002) were related to the utilization of non-invasive monitoring equipment. In the simulated case vignette, 49.7% (183/368) of respondents reported performing fluid responsiveness and volume status (FR-VS) assessment. Despite differences in training centers (P=0.005) and educational backgrounds (P=0.030), FR-VS assessment was not related to the volume expansion decision.

CONCLUSIONS

There is a large variability in use advanced HM parameters, an increasing awareness and acceptance of non-invasive HM devices and a potential need for hemodynamic education and training in pediatric intensive care medicine in China.

Integrating Focused Cardiac Ultrasound Into Pediatric Septic Shock Assessment

OBJECTIVES

To assess focused cardiac ultrasound impact on clinician hemodynamic characterization of patients with suspected septic shock as well as expert-generated focused cardiac ultrasound algorithm performance.

DESIGN

Retrospective, observational study.

SETTING

Single-center, noncardiac PICU.

PATIENTS

Less than 18 years old receiving focused cardiac ultrasound study within 72 hours of sepsis pathway initiation from January 2014 to December 2016.

INTERVENTIONS

Hemodynamics of patients with suspected septic shock were characterized as fluid responsive, myocardial dysfunction, obstructive physiology, and/or reduced systemic vascular resistance by a bedside clinician before and immediately following focused cardiac ultrasound performance. The clinician's post-focused cardiac ultrasound hemodynamic assessments were compared with an expert-derived focused cardiac ultrasound algorithmic hemodynamic interpretation. Subsequent clinical management was assessed for alignment with focused cardiac ultrasound characterization and association with patient outcomes.

MEASUREMENTS AND MAIN RESULTS

Seventy-one patients with suspected septic shock (median, 4.7 yr; interquartile range, 1.6-8.1) received clinician performed focused cardiac ultrasound study within 72 hours of sepsis pathway initiation (median, 2.1 hr; interquartile range, -1.5 to 11.8 hr). Two patients did not have pre-focused cardiac ultrasound and 23 patients did not have post-focused cardiac ultrasound hemodynamic characterization by clinicians resulting in exclusion from related analyses. Post-focused cardiac ultrasound clinician hemodynamic characterization differed from pre-focused cardiac ultrasound characterization in 67% of patients (31/46). There was substantial concordance between clinician's post-focused cardiac ultrasound and algorithm hemodynamic characterization (33/48; κ = 0.66; CI, 0.51-0.80). Fluid responsive (κ = 0.62; CI, 0.40-0.84), obstructive physiology (к = 0.87; CI, 0.64-1.00), and myocardial dysfunction (1.00; CI, 1.00-1.00) demonstrated substantial to perfect concordance. Management within 4 hours of focused cardiac ultrasound aligned with algorithm characterization in 53 of 71 patients (75%). Patients with aligned management were less likely to have a complicated course (14/52, 27%) compared with misaligned management (8/19, 42%; p = 0.25).

CONCLUSIONS

Incorporation of focused cardiac ultrasound in the evaluation of patients with suspected septic shock frequently changed a clinician's characterization of hemodynamics. An expert-developed algorithm had substantial concordance with a clinician's post-focused cardiac ultrasound hemodynamic characterization. Management aligned with algorithm characterization may improve outcomes in children with suspected septic shock.

Practice Patterns of Central Venous Catheter Placement and Confirmation in Pediatric Critical Care

Optimal practices for the placement of central venous catheters (CVCs) in critically ill children are unclear. This study describes the clinical practice of pediatric critical care medicine (PCCM) providers regarding CVC placement, including site selection, confirmation practices and assessment of complications. Two-hundred fourteen PCCM providers responded to an electronic survey, including 170 (79%) attending physicians, 30 (14%) fellow physicians, and 14 (7%) advanced practice providers. PCCM providers most commonly place internal jugular (IJ) and femoral CVCs, with subclavian CVCs and peripherally inserted central catheters (PICCs) placed less commonly (IJ 99%, femoral 95%, subclavian 40%, PICC 19%). The IJ is the most preferred site (128/214 (60%)); decreased infection risk is the most common reason for preferring this site. The subclavian is the least preferred site (150/214 [70%]) due to concern for increased risk of complications (51%) and personal discomfort with the procedure (49%). One-hundred twenty-six (59%) of respondents reported receiving formal ultrasound (US) or echocardiography training. Respondents reported using dynamic US guidance for placement in 90% of IJ, 86% of PICC, 78% of femoral, and 12% of subclavian CVCs. Plain radiography (X-ray) was the most preferred modality for confirming CVC tip position (85%) compared with US (9%) and no imaging (5%). Most providers reported using X-ray to evaluate for pneumothorax following upper extremity CVC placement, with only 5% reporting use of US and none relying on physical exam alone. This study demonstrates wide variability in PCCM providers' CVC placement practices. Potential training gaps exist for placement of subclavian catheters and use of US.

A Novel Tool for Teaching Cardiac Point-of-Care Ultrasound: An Exploratory Application of the Design-Based Research Approach

OBJECTIVES

To develop a competency-based educational tool for cardiac point-of-care ultrasound image interpretation using the design-based research approach.

DESIGN

In accordance with design-based research, multiple methods were used to determine that learners would benefit from achieving competency in cardiac point-of-care ultrasound image interpretation before they attempted it at the bedside. A competency-based educational tool was designed and underwent a rapid prototyping process with experts. Evaluative data was used to redesign and reevaluate the educational tool with a new group of learners to improve its effectiveness.

SETTING

Large, university-based children's hospital.

SUBJECTS

Pediatric critical care attending physicians, fellow physicians and advanced practice providers, and pediatric resident physicians.

INTERVENTIONS

Integrating mastery learning and deliberate practice as theoretical frameworks, the authors designed an online "Image Library" composed of 90 questions of cardiac point-of-care ultrasound image clips with varying degrees of pathology that were organized into three levels of difficulty. Learners answered a set of 10 questions, learned from feedback, and repeated an additional set in the same difficulty until achieving a predefined level of mastery.

MEASUREMENTS AND MAIN RESULTS

Two learning cycles were implemented with a total of 41 learners. Forty learners (98%) were able to demonstrate mastery on the Image Library and required a range of 30 to 210 questions to do so. On a 10-question final assessment, learners scored an average of 72%, while experts and novices scored 83% and 17%, respectively. On a 5-point scale, learners rated the quality of the Image Library for facilitation of learning (median 5), enjoyment of learning (5), and useful knowledge and skills to improve clinical practice (5).

CONCLUSIONS

An effective and innovative tool for teaching cardiac point-of-care ultrasound image interpretation was developed using the design-based research approach. Our results demonstrate the importance of individualized learning timelines for ultrasound image interpretation.

Point of care ultrasound for all by all: A multidisciplinary survey across a large quaternary care medical system

PURPOSE

We sought to understand current POCUS practices and comfort as well as assess opinions about POCUS across our medical system via a survey to guide program development.

METHODS

This study was conducted as a 19 question RedCap survey with multiple parts. Respondents were queried for demographics as well as experience with, attitudes toward, and clinical use of POCUS in common critical care scenarios.

RESULTS

The survey was completed by 343 individuals, a response rate of 30%. Most respondents "agreed" that POCUS is a needed skill and helped them provide safer care (78% and 86% agreement). Most faculty and trainees reported some POCUS training (62% and 88%) and at least weekly use. Trainees rated themselves more comfortable than faculty for most exam types. The majority of faculty rated their POCUS education as inadequate while trainees had mixed responses.

CONCLUSIONS

POCUS is a frequently used tool, yet users are less confident in their skills than expected. POCUS applications are viewed as needed for future practice but there is a substantial need for improved education among faculty and trainees. Pooling resources and sharing educational initiatives across multiple specialties may help improve POCUS implementation.

Current Clinical Practice in Point-of-Care Ultrasound Use in the PICUs Across Europe

OBJECTIVES

1) To investigate the current practice in point-of-care ultrasound use in PICUs across Europe; 2) to understand the barriers for point-of-care ultrasound implementation in the clinical practice; 3) to identify existing point-of-care ultrasound training programs; and 4) to assess training needs.

DESIGN

Cross-sectional electronic survey.

SUBJECTS

Medical directors of European PICUs.

MEASUREMENTS AND MAIN RESULTS

The response rate was 42.3%; 142 of the 336 invited PICU medical directors from 26 European countries completed the survey. The clinicians in almost all the PICUs across Europe were reported to use point-of-care ultrasound in some form. A significant variation in the clinical practice according to the patient characteristics and presence of a fellowship training program was observed. PICUs with cardiosurgical patients reported using point-of-care ultrasound significantly more often than others. Ultrasound-guided vascular access was the most common point-of-care ultrasound indication, except in PICUs providing joint care for neonates and children. Units with a fellowship training program reported an increased use of point-of-care ultrasound for hemodynamic evaluation, during resuscitation and a positive impact on collaboration with imaging specialties. Although no barrier was deemed substantial to impede point-of-care ultrasound implementation, a number of potential hindrances to its implementation were reported-such as lack of formal training curriculum, collaborative learning opportunities, and quality assurance processes. Bedside informal teaching in point-of-care ultrasound was reported the most common method to acquire point-of-care ultrasound skills.

CONCLUSIONS

Point-of-care ultrasound is being used extensively across heterogeneously organized PICU settings in Europe. However, there remains a significant variation in the clinical practice across the units. Clear needs for improved point-of-care ultrasound training programs and clinical governance structure were identified. Evidence-based point-of-care ultrasound guidelines, structured training programs dedicated to neonatal and pediatric intensive care settings, and educational research in point-of-care ultrasound use may help in strengthening clinical governance, making clinical practice uniform and enhancing quality assurance.

[Ultrasound-guided cannulation or by pulse palpation in the intensive care unit]

INTRODUCTION

Ultrasound (US) guidance increases the success rate and decreases complications during central venous catheterisation (CVC). The benefits of US guidance in arterial catheterisation are less clear. The aim of this study is to compare the outcomes of US-guided arterial catheterisation with the traditional landmark (LM) technique in critically ill children.

METHODS

A prospective multicentre study was carried out in 18 Paediatric Intensive Care units in Spain during a 6-months period. Ultrasound guided and landmark techniques were compared in terms of cannulation technical success and immediate mechanical complications.

RESULTS

A total of 161 procedures were performed on 128 patients (78 procedures in the US group and 83 in the LM groups). The median (interquartile range) age and weight of the cohort was 11months (2-52), and 10kg (4-17), respectively. More than half (59.6%) were male. US was used mainly in big (number of beds 11 [8-16] vs 6 [4-10], p < 0,001) and high complexity intensive care units (cardiac surgery program 76.9% vs. 25.6%, P<.001) as well as in smaller children [weight 5.7kg (3.8-13) vs 11.5kg (4.9-22.7), P<.001]. Almost half (49.7%) of the procedures were performed by an inexperienced operator (paediatric resident, or staff with less than 5years of clinical experience in the PICU), and only 24.4% had performed more than 50 US-guided vascular access procedures before the study. There were no significant differences between US and LM techniques in terms of first-attempt success (35.8% vs 33.7%, P=.773), overall success (75.6% vs 71.1%, P=.514), number of puncture attempts [2 (1-4) vs 2 (1-3), P=.667] and complications (16.6% vs 25.6%, P=.243). Adjustment by potential confounders using multivariate regression models did not modify these results. Subgroup analyses showed that US outperformed LM technique in terms of overall success (83.7% vs 62.7%, P=.036) and complications (10,8% vs 32.5%, P=.020) only when procedures where performed by less-experienced operators.

CONCLUSIONS

In this prospective observational multicentre study, US did not improve arterial cannulation outcomes compared to the traditional LM technique in critically ill children. US-guided arterial cannulation may offer advantages when cannulation is performed by inexperienced operators.

Moving Beyond the Stethoscope: Diagnostic Point-of-Care Ultrasound in Pediatric Practice

Diagnostic point-of-care ultrasound (POCUS) is a growing field across all disciplines of pediatric practice. Machine accessibility and portability will only continue to grow, thus increasing exposure to this technology for both providers and patients. Individuals seeking training in POCUS should first identify their scope of practice to determine appropriate applications within their clinical setting, a few of which are discussed within this article. Efforts to build standardized POCUS infrastructure within specialties and institutions are ongoing with the goal of improving patient care and outcomes.

[Point-of-care ultrasound: Is it time to include it in the paediatric specialist training program?]

Point-of-care ultrasound (POCUS) has become an essential tool for clinical practice in recent years. It should be considered as an extension of the standard physical examination, which complements and enriches it without substituting it. POCUS enables the physician to answer specific clinical questions about the diagnosis, to understand better the pathophysiological context, to orientate the treatment, and to perform invasive procedures more safely. Despite its current use in many centres, and in most paediatric sub-specialties, there are currently no specific recommendations addressing educational aims in the different training areas, as well as methodology practice and the certification process in paediatrics. These ingredients are essential for POCUS implementation in daily practice, with a quality guarantee in terms of efficiency and safety. Several POCUS experts in different paediatric medicine environments performed a non-systematic review addressing the main paediatric POCUS applications in paediatrics. The lack of educational programs in POCUS in Spain is also discussed, and the experience in the United States of America in this topic is provided. Considering the current situation of POCUS in paediatrics, we strongly believe that it is urgent to establish evidence-based recommendations for POCUS training that should be the base to develop educational programs and to include POCUS in the paediatric residency training.

Getting to know a familiar face: Current and emerging focused ultrasound applications for the perioperative setting

Ultrasound technology is available in many pediatric perioperative settings. There is an increasing number of ultrasound applications for anesthesiologists which may enhance clinical performance, procedural safety, and patient outcomes. This review highlights the literature and experience supporting focused ultrasound applications in the pediatric perioperative setting across varied disciplines including anesthesiology. The review also suggests strategies for building educational and infrastructural systems to translate this technology into clinical practice.
