Point-of-care ultrasound in pediatric anesthesiology and critical care medicine

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.

Cuffed versus uncuffed endotracheal tubes in neonates undergoing noncardiac surgeries: A randomized controlled trial

BACKGROUND

The efficacy and safety of cuffed endotracheal tubes (ETTs) in neonates are still unclear, this study aimed to assess the efficacy of cuffed versus uncuffed ETTs in neonate undergoing noncardiac surgeries.

METHODS

Neonates scheduled for noncardiac surgeries were randomized into two groups according to the type of airway device during general anesthesia: cuffed ETT group (n = 60) and the uncuffed ETT group (n = 60). The primary outcome was the incidence of ETT exchange to find the appropriate ETT. Other outcomes included: duration of intubation, lung ultrasound score, and incidence of postoperative complications (croup, wheezes, hypoxia, etc.).

RESULTS

The frequency of ETT exchange was lower in the cuffed ETT group compared to the uncuffed one {1 (1.7%) vs. 28 (46.7%), p = .0001; relative risk [95% confidence interval]: 0.54 [0.43-0.69]}. Postoperative adverse events were comparable between both groups except for significantly higher post extubation croup in the uncuffed ETT group compared to the cuffed ETT {10 (16.7%) vs. 3(5%), p value = .04, relative risk (95% confidence interval): 1.14 (1-1.29)}.

CONCLUSION

In full term neonates undergoing noncardiac surgeries, the use of cuffed ETT was associated with less need to tracheal tube exchange and less incidence of postoperative croup, without increasing the postoperative respiratory complications compared to uncuffed ETT.

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.

Current Use, Training, and Barriers of Point-of-Care Ultrasound in Anesthesiology: A National Survey of Veterans Affairs Hospitals

OBJECTIVES

The purpose of this study was to determine current use, training needs, and barriers to point-of-care ultrasound (POCUS) use among anesthesiologists in practice.

DESIGN

Multicenter, prospective, observational study.

SETTING

Anesthesiology departments in the Veterans Affairs Healthcare System in the United States.

PARTICIPANTS

Chiefs of staff and chiefs of anesthesiology departments.

INTERVENTIONS

A web-based survey was conducted between June 2019 and March 2020. Chiefs of staff answered questions about facility-level POCUS use, training, competency, and policies. Anesthesiology chiefs responded to a follow-up survey with specialty-specific POCUS questions. The results of the 2020 survey were compared with a similar survey conducted by the authors' group in 2015.

MEASUREMENTS AND MAIN RESULTS

All chiefs of staff (n = 130) and 77% of anesthesiology chiefs (n = 96) completed the survey. The most common POCUS applications used were central and peripheral vascular access (69%-72%), peripheral nerve blocks (66%), and evaluation of cardiac function (29%-31%). Compared with 2015, there was a statistically significant increase in desire for training (p = 0.00015), but no significant change in POCUS use (p = 0.31). Training was most desired for volume-status assessment (52%), left ventricular function (47%), pneumothorax (47%), central line placement (40%), peripheral nerve blocks (40%), and pleural effusion (40%). The most common barriers to POCUS use were lack of funding for training (35%), trained providers (33%), and training opportunities (28%).

CONCLUSIONS

A significant increase in desire for POCUS training was seen among anesthesiologists practicing in the Veterans Affairs healthcare system since 2015, and lack of training continues to be a top barrier for POCUS use among anesthesiologists.

Neonatal POCUS: Embracing our modern day "stethoscope"

The dramatic technologic advancements seen in ultrasound have accelerated the growth of point-of-care ultrasound (POCUS) in medicine. Neonatology has lagged behind other pediatric and adult specialties in incorporating POCUS into clinical practice despite there being numerous applications in cardiac and non-cardiac arenas. Widely available training programs are aiding in improving this situation but significantly more structure and orchestration for neonatal POCUS dissemination will be needed to fully actualize the potential for POCUS to augment its widespread clinical application.

Pediatric Residency Point-of-Care Ultrasound Training Needs Assessment and Educational Intervention

Background

Prior studies showed that point-of-care ultrasound (POCUS) training is not commonly offered in pediatric residency. We assessed the need for a pediatric POCUS curriculum by evaluating pediatric trainees’ attitudes toward the use of POCUS and identifying barriers to training. We also aimed to evaluate the impact of a POCUS educational intervention on self-efficacy and behavior.

Methods

We conducted a cross-sectional survey of pediatric residents in a single large freestanding children’s hospital distributed via an institutional listserv and administered online. The survey included opinion-rating of statements regarding POCUS and barriers to training. We also offered a two-week POCUS course with online modules and hands-on scanning. Participating residents completed pre- and post-course knowledge assessments and follow-up surveys up to 12 months following the course to assess POCUS use and self-report confidence on POCUS indications, acquisition, interpretation, and clinical application.

Results

Forty-nine respondents were included in the survey representing all three pediatric levels with 16 specialty interest areas. Ninety-six percent of trainees reported that POCUS is an important skill in pediatrics. Ninety-two percent of trainees reported that residency programs should teach residents how to use POCUS. The most important perceived barriers to POCUS training were scheduling availability for POCUS rotations and lack of access to an ultrasound machine. Fourteen participants completed the pre- and post-course knowledge tests, with eight and six participants also completing the six- and 12-month follow-up surveys, respectively. Self-ratings of confidence were significantly improved post-intervention in indications (P = 0.007), image acquisition (P = 0.002), interpretation (P = 0.002), and clinical application (P = 0.004). This confidence improvement was sustained up to 6-12 months (P = 0.004-0.032). Participants also reported higher categorical POCUS use after course completion (P = 0.031).

Conclusions

Pediatric trainees perceive POCUS as an important skill, hold favorable opinions towards the use of POCUS, and support POCUS training within a pediatric residency. A POCUS course can improve resident POCUS knowledge, instill confidence, and motivate higher POCUS use. Further study is needed to evaluate POCUS applications in pediatric medicine to develop a standardized POCUS curriculum and establish a training guideline for pediatric residency.

Residents' Perspective on Need for Point-of-Care Ultrasound Education During Pediatric Residency

OBJECTIVES

Many medical disciplines incorporate point-of-care ultrasound (POCUS) into their practice. Despite well-defined applications, POCUS has not been widely adopted in pediatrics and is not commonly taught during residency. Our objective was to profile the current state of POCUS education in pediatric residency training from the resident perspective.

METHODS

We surveyed pediatric trainees about their POCUS education, general opinions about POCUS, and perceived barriers to POCUS training in residency. We distributed the survey to a random sample of Ohio pediatric residents, stratified by program size and training level. Descriptive statistics were used to characterize responses.

RESULTS

We sampled 66.4% of the population (371 of 559) of Ohio pediatric residents and achieved a response rate of 59.3%. Only 15% of respondents received POCUS training during residency, with 85% having never performed a POCUS scan. Most (86%) desired POCUS education and 67% believed it should be required during residency. Residents felt that POCUS would be useful for procedural guidance (95%), clinical diagnosis (94%), and patient safety (74%). Most residents (61%) believed POCUS education would benefit their careers, particularly those planning on subspecialization. Barriers to POCUS education included lack of an established curriculum (75%), competing educational priorities (58%), and a shortage of qualified instructors (52%).

CONCLUSIONS

Although Ohio pediatric residents do not receive formal POCUS education in residency, they desire such training and believe it would benefit their future practice. Consensus on scope of practice, development of a standardized curriculum, and increased faculty training in POCUS may help address this educational gap.

Ultrasound of pneumothorax in neonates: Diagnostic value of the anterior transverse plane and of mirrored ribs

INTRODUCTION

Point-of-care lung ultrasound is increasingly used to diagnose pneumothorax efficiently and safely in neonates.

OBJECTIVES

This study aimed to evaluate the usefulness of the central and anterior transverse thoracic plane in the ultrasound diagnosis of pneumothorax, analyze the diagnostic value of the "mirrored ribs" sign, and evaluate the predictive value of the lung point location for the need of pleural drainage.

METHODS

Retrospective cohort study of all newborns admitted to the neonatal intensive care unit of the Basurto University Hospital (Bilbao, Spain) due to respiratory distress and with ultrasound, with or without pneumothorax, between January 2014 and December 2020.

RESULTS

The presence of A-lines behind the sternum in the anterior transverse plane in newborns with pneumothorax (N = 311) and controls (N = 195) was compared. A-lines were present in 98.9% of newborns with pneumothorax compared to none in the controls (p < .0001). Diagnosis of pneumothorax with the anterior transverse plane presented high interobserver reproducibility (κ = 0.92, 95% confidence interval: 0.84-1.00). In contrast, the "mirrored ribs" sign in the anterior longitudinal plane was observed in 35.6% of patients with pneumothorax and in 36.9% of controls (p = .1505). A significant association was observed between lung point location and the need for pleural drainage (p < .0001).

CONCLUSIONS

A-lines in the anterior transverse plane is a simple ultrasound sign which presents high sensitivity, specificity, and reproducibility for the diagnosis of pneumothorax. The mirrored ribs sign showed low diagnostic utility. Patients with severe pneumothorax in lung ultrasound are most likely to require thoracic drainage.

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.

Training medical students in physical examination and point-of-care ultrasound: An assessment of the needs and barriers to acquiring skills in point-of-care ultrasound

BACKGROUND:

With growth of the use of point of care ultrasound (PoCUS) around the world, some medical schools have incorporated this skill into their undergraduate curricula. However, because of epidemiology of disease and regional differences in approaches to patient care, global application of PoCUS might not be possible. Before creating a PoCUS teaching course, it is critical to perform a needs analysis and recognize the training obstacles.

MATERIALS AND METHODS:

A validated online questionnaire was given to final-year medical students at our institution to evaluate their perceptions of the applicability of specific clinical findings, and their own capability to detect these signs clinically and with PoCUS. The skill insufficiency was assessed by deducting the self-reported clinical and ultrasound skill level from the perceived usefulness of each clinical finding.

RESULTS:

The levels of expertise and knowledge in the 229 students who participated were not up to the expected standard. The applicability of detection of abdominal aortic aneurysm (AAA) (3.9 ± standard deviation [SD] 1.4) was the highest. However, detection of interstitial syndrome (3.0 ± SD 1.1) was perceived as the least applicable. The deficit was highest in the detection of AAA (mean 0.95 ± SD 2.4) and lowest for hepatomegaly (mean 0.57 ± SD 2.3). Although the majority agreed that training of preclinical and clinical medical students would be beneficial, 52 (22.7%) showed no interest, and 60% (n = 136) reported that they did not have the time to develop the skill.

CONCLUSION:

Although medical students in Saudi Arabia claim that PoCUS is an important skill, there are significant gaps in their skill, indicating the need for PoCUS training. However, a number of obstacles must be overcome in the process.

Age-Related Changes in Upper Airway Anatomy Via Ultrasonography in Pediatric Patients

PURPOSE

Ultrasonography is a portable, noninvasive tool that may be used to evaluate the upper airway. The purpose of our study was to present a systematic approach to identify salient features of the pediatric airway and determine whether ultrasonography can identify anatomical changes that occur with growth and development.

METHODS

We present a prospective, observational trial where patients included were between 1 day and 10 years of age presenting for elective surgery who had no known history of unfavorable airway pathology. We sequentially obtained 5 ultrasound views under anesthesia: (1) sagittal sternal notch view of the trachea, (2) sagittal longitudinal view of trachea (LT), (3) axial view at the level of the vocal cords (AVC), (4) axial view at the level of the cricoid membrane (AC), and (5) sagittal longitudinal submental space view (SM). A broadband linear array transducer was used to identify airway structures and perform measurements.

RESULTS

Eighty-four percent of enrolled patients underwent airway imaging and were analyzed using multiple regression and Spearman correlation (ρ). In view 1, tracheal diameter via sagittal sternal notch view was immeasurable because of air disturbance. In the LT view, the distance from the skin to the cricothyroid membrane (LT1) did not statistically increase with age in days (P = 0.06); however, the distance from the cricoid to thyroid cartilage (LT2) did correlate to age (P < 0.001; 99% confidence interval [CI], 1.8 × 10-5, 7.7 × 10-5; ρ = 0.77, P = 0.001). We found a statistically significant relationship between age and the distance between the anterior and posterior commissures (AVC2; P < 0.001; 99% CI, 1.0 × 10-4, 1.7 × 10-4; ρ = 0.80, P < 0.001), the distance from the skin to the posterior commissure (AVC3; P < 0.001; 99% CI, 9.6 × 10-5, 2.0 × 10-4; ρ = 0.73, P < 0.001), the distance to the cricoid cartilage (AC; P < 0.001; 99% CI, 2.0 × 10-5, 7.7 × 10-5; ρ = 0.66, P < 0.001), and the distance from the tongue base to the soft palate (SM2; P < 0.001; 9% CI, 1.8 × 10-4, 3.9 × 10-4; ρ = 0.85, P < 0.001). There were no significant relationships between age and AVC1 (P = 0.16) and SM1 (P = 0.44).

CONCLUSIONS

Airway ultrasound is a feasible tool to evaluate the pediatric airway in children younger than 10 years; however, the detection of age-related changes of certain structures is limited to select measurements.

Bedside Ultrasound for Procedural Assistance in Pediatrics

Point-of-care ultrasound (POCUS) is a noninvasive imaging tool with both diagnostic and therapeutic applications. In this article, the author will review the role of POCUS for vascular access, endotracheal intubation, lumbar puncture, chest tube, and diagnosing coronavirus disease 2019 lung pathology. This will include a review of the evidence, technique, and strategies for optimizing performance of these procedures. [Pediatr Ann. 2021;50(10):e404-e410.].

Training pediatric residents in point-of-care ultrasound: An assessment of the needs and barriers to acquire the skill

Introduction

The use of point-of-care ultrasound (POCU) is increasing globally. However, owing to the epidemiology of diseases and local management strategies, POCU may not be universally applicable. Before developing a POCU training program, because of limited resources for medical education, it was pivotal to conduct a needs assessment and identify the training barriers.

Methods

This study used a validated paper questionnaire. The survey instrument was distributed to 120 pediatric residents (male 60, female 60) training at our institution to assess their self-reported level of skill in POCU, and their perceptions with regard to the applicability of POCU, measured with a 5-point Likert scale. The skills deficit was measured by subtracting the self-reported level of skills in lung, cardiac, and abdominal POCU from the perceived applicability of POCU.

Results

Fifty-nine residents participated, resulting in a response rate of 50 and 48% (n = 29) for the male group, and 50% (n = 30) for the female group. The level of knowledge and proficiency was low. Scanning for free abdominal fluid was deemed the most applicable (mean 4.2 ± SD 1.1); however, the use of POCU to detect consolidation was considered least applicable (mean 2.7 ± SD 1.3). The skills deficit was highest for an abdominal POCU (mean 2.4 ± SD 1.6) and lowest for lung ultrasound (mean 1.4 ± SD 1.6). Although the majority (n = 48) agreed that this skill was essential, 3 (5%) had no interest, and 39% (n = 23) indicated a lack of time to acquire the skill.

Conclusions

Though pediatric residents in Saudi Arabia agree that POCU is an essential skill, large skill deficits exist, supporting the necessity to provide POCU training. However, there are several barriers to overcome to achieve this.

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.

Accuracy of Clarius, Handheld Wireless Point-of-Care Ultrasound, in Evaluating Prostate Morphology and Volume Compared to Radical Prostatectomy Specimen Weight: Is There a Difference between Transabdominal vs Transrectal Approach?

Background: Prostate size estimation is a valuable clinical measure widely utilized in urology. This study evaluated the accuracy of preoperative transabdominal ultrasound (TAUS) compared to radical prostatectomy specimens and transrectal ultrasound (TRUS) in estimating prostate volume and identifying presence of median lobe, across different size groups, using the standard ellipsoid formula. The effect of median lobe on accuracy was also assessed. Materials and Methods: Ninety-eight men undergoing robot-assisted radical prostatectomy were enrolled in this study. Preoperative evaluation of prostate volume was done using measurements obtained from TAUS using the Clarius C3 handheld wireless point-of-care ultrasound (POCUS) and from TRUS Clarius EC7. Participants were grouped based on prostate size (<30, 30-60, and >60 g). Mean absolute percentage of error was used to evaluate accuracy. Mean percentage of error determined if there was an overestimation or underestimation. Correlation between each TAUS size group, true prostate weight and TRUS was assessed. Results: Irrespective of body mass index, TAUS accurately identified median lobe in all men. No statistically significant difference was found between specimen weight and TAUS prostate size for the >60 g group. Among this same group, a strong correlation was noted between specimen weight and TAUS prostate size (r = 0.911, p < 0.001). There was also a strong correlation between TAUS and TRUS measurements for this group (r = 0.950, p < 0.001). Presence of median lobe did not have an impact on measurement accuracy. Conclusions: Bedside handheld wireless POCUS provides rapid, inexpensive, noninvasive, and clinically accurate TAUS prostate assessments for larger prostates. Such features as identifying median lobes and measuring prostate volumes are valuable tools, whereas patient counseling on lower urinary tract symptoms, elevated prostate-specific antigen, and benign prostate hyperplasia are surgical options.

[Lung Ultrasound in Neonatology to diagnose a Pneumothorax (part two): A Guideline]

Lung ultrasound is a fast and reliable diagnostic tool in the detection of a neonatal pneumothorax. This tutorial provides basic information for understanding and detecting the generated artefacts, such as A-lines, B-lines, and the lung point. Essential knowledge of these artefacts allows for rule-in and rule-out criteria of a pneumothorax diagnosis. Lung ultrasound could help to reduce the use of radiation in neonatology in the future.

Perioperative Point-of-Care Ultrasound in Children

Anesthesiologists and other acute care physicians perform and interpret portable ultrasonography—point-of-care ultrasound (POCUS)—at a child’s bedside, in the perioperative period. In addition to the established procedural use for central line and nerve block placement, POCUS is being used to guide critical clinical decisions in real-time. Diagnostic point-of-care applications most relevant to the pediatric anesthesiologist include lung ultrasound for assessment of endotracheal tube size and position, pneumothorax, pleural effusion, pneumonia, and atelectasis; cardiac ultrasound for global cardiac function and hydration status, and gastric ultrasound for aspiration risk stratification. This article reviews and discusses select literature regarding the use of various applications of point-of-care ultrasonography in the perioperative period.

Mirrored Ribs: A Sign for Pneumothorax in Neonates

OBJECTIVES

To evaluate if "mirrored ribs"-a mirroring of chest structures-is a sign for pneumothorax in lung ultrasound in neonates.

DESIGN

Retrospective study.

SETTING

Medical University Vienna/General Hospital, Vienna, Austria.

PATIENTS

All neonates admitted with clinical signs of pneumothorax between July 2018 and February 2019.

INTERVENTIONS

Chest radiograph and lung ultrasound in succession.

MEASUREMENTS AND MAIN RESULTS

Anterior-posterior chest radiograph and lung ultrasound were compared. "Mirrored ribs" were defined as mirroring of at least one rib and intercostal muscles in B-mode in the absence of B-lines. Twenty-nine cases in 26 patients were considered. Pneumothorax was diagnosed in 55% of cases using reported signs for pneumothorax in lung ultrasound and in 31% using chest radiograph. Lung ultrasound identified all pneumothoraces visible in chest radiograph. "Mirrored ribs" were visible in all patients with signs for pneumothorax and in none without signs for pneumothorax in lung ultrasound, representing a specificity and sensitivity of 100% compared with reported signs for pneumothorax in lung ultrasound.

CONCLUSIONS

The occurrence of "mirrored ribs" in lung ultrasound in combination with absence of lung sliding, absence of B-lines and lung point might facilitate the rapid recognition of pneumothorax in neonates.

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.
