Reflections of a paediatric pulmonologist: strategies for optimising lung function tests in preschool children.

In recent years, our clinical practice as paediatric pulmonologists has focused on refining strategies to optimise pulmonary function tests (PFTs) for preschool children, particularly those aged as young as 2 years and 5 months. This viewpoint reflects on our experience conducting over 7000 spirometry and impulse oscillometry (IOS) tests, sharing practical insights into achieving high success rates with young children. We emphasise the importance of creating a child-friendly, minimally stimulating environment, tailored communication using familiar and engaging language, and leveraging gamification and positive reinforcement. In particular, we highlight the use of role-playing as an effective engagement strategy, allowing children to teach a stuffed toy how to perform the test. Furthermore, we differentiate the approaches required for spirometry, which demands active cooperation, and IOS, which allows for tidal breathing and is more suitable for younger or less cooperative children. Through these strategies, we have achieved consistent, technically acceptable results in preschool-aged children, aligning with the latest standardisation guidelines. Our findings demonstrate the value of adaptability, patience and creativity in paediatric PFTs, suggesting that these approaches improve not only test accuracy but also the overall experience for both children and caregivers. Future research should further investigate these techniques to enhance paediatric pulmonary testing protocols.

A Guide to Pediatric Antibiotic Allergy Testing: A Report From the US Drug Allergy Registry.

Pediatric antibiotic labels are common, and unnecessary antibiotic avoidance is associated with negative personal and public health outcomes; as a result, there is an increasing emphasis on the importance of pediatric antibiotic allergy evaluations. Different testing strategies have been advised, including skin testing and challenge testing with varied doses and duration. Established consensus testing protocols are lacking. The US Drug Allergy Registry Pediatrics (USDAR-Peds) is a multisite prospective study designed for epidemiology and outcome evaluations of pediatric drug hypersensitivity reactions. Interpretation of multisite data requires a uniform clinical approach, and the USDAR-Peds standardized protocols were developed in response to this need. This rostrum aims to provide a rationale and framework for standardization for pediatric antibiotic allergy protocols and assessment of positive reactions through a pediatric-specific adaptation of the USDAR immediate reaction grading scale to create consistency for multisite research collaboration efforts such as USDAR-Peds.

Anorectal manometry and urodynamics in children with spina bifida: can we predict the colonic dysmotility from bladder dysfunction?

IntroductionSpina bifida is a condition that impacts the development of the neural tube leading to urological and gastrointestinal symptoms. Both systems are influenced together due to their shared innervation and embryological origin. Despite its impact on health and well-being there has been limited research on the relationship between manometry results and urodynamic tests, in this patient population. The aim of this study was to delineate the association of neurogenic bladder/bowel dysfunction with anorectal manometry and urodynamics.Materials and methodsUrodynamics and anorectal manometry were used to analyse the neurogenic bowel and bladder dysfunctions in 29 paediatric patients with spina bifida. Those children who had previous anorectal surgical interventions were excluded from the study. Patients were grouped according to the level of spinal defect to lower or upper defect. In this study, parameters such as bladder compliance, postvoid residual volume, detrusor activity, anorectal pressures, and rectal compliance were considered. Group comparison tests were performed using standardized paediatric protocols for data analysis as well as correlation tests. A p-value less than 0.05 was considered significant at all levels.ResultsA total of 29 patients with spina bifida were identified. Of these, 14 were male and 15 were female. Bladder function differed among the patients in the lower defect (LD, n:18) and upper defect (UD, n:11) groups. LD group exhibited lower bladder volumes (175.45 ± 106.19 mL) compared to the UD group (266.83 ± 102.54 mL, p < 0.05). All LD and 72.7% of UD had detrusor sphincter dyssynergia. There was positive correlation between functional bladder parameters and bowel dysfunction, such as rectoanal inhibitory reflex (RAIR) and maximum filling pressures of the bladder (rho = 0.569, p < 0.05). There was also a significant correlation between rectal compliance and bladder volumes.ConclusionsAssociation of neurogenic bowel and bladder dysfunction is a complex issue which requires personalized approach for managing the consequences. In children with neurogenic bladder dysfunction increased RAIR activity may be a sign for colonic dysmotility of neurogenic origin. This study may also pave the way for delineation of the mechanism under the generation of RAIR which is thought to be only intrinsic in origin. To optimize treatment modalities, full assessment with anorectal manometry and urodynamic studies should be done in patients with spina bifida.Clinical trial registrationThis study was not performed on volunteer patients. Clinical study enrolment is not required as this study was obtained from urodynamics and anorectal manometry performed in patients with neurogenic bladder/bowel and during clinical follow-up.

Traumatic pediatric cervical spine injury-a proposed clearance algorithm incorporating a 24-h time delay.

Pediatric cervical spine injury (pCSI) is rare. Physiological differences necessitate alternate management from adults. Yet, no standardized pediatric protocols exist. Previous investigations applying adult-validated clinical decision rules (CDRs)-NEXUS Criteria (NX) and Canadian C-spine Rules (CCR)-to children are mixed. We hypothesized a combined NX + CCR approach applied at a delayed 24-h time point would enhance screening efficacy in select patients. We conducted a retrospective review of a prospectively-collected database over 15months at a pediatric-capable Level-1 trauma center. Age and mechanism determined initial inclusion. NX and CCR criteria were collected and retroactively applied on arrival (T0) and 24h later (T1). Statistical analyses were performed in SPSS. A total of 306 patients met inclusion. Current practices compel computed tomography (CT) overuse for craniocervical evaluations: 298 (97.4%) underwent ≥ 1 CT. Of cervical spines imaged (n = 175), 161 (92.0%) underwent CT while 74 (42.3%) underwent magnetic resonance imaging with 14 (18.9%) completed after 72h. Of collars placed on arrival (n = 181), 136 (75.1%) were cleared before discharge with 86 (63.2%) CTs denoting preferred clearance modality; CT utilization was unchanged when stratified by age < 5years (p = 0.819). Notably, we found more patients met NX + CCR criteria at T1 versus T0 (p = 0.008) without missed pCSI resulting in imaging overutilization in 15 (8.6%) patients. We showed incorporating a 24-h time delay before a second CDR reapplication may enhance screening efficacy in pCSI. Our new algorithm combines these findings with other literature-based recommendations and may represent a standardizable option for evaluating pCSI in the acute trauma setting.

Introduction of a LAT gel and low-dose midazolam sedo-analgesia protocol for pediatric skin suture in the emergency department: simpler is better.

skin lacerations are one of the main causes of children's referral to the emergency department (ED). We introduced in our general ED a pediatric sedo-analgesia protocol (SAP) for suturing skin wounds using LAT gel, a local anesthetic solution of lidocaine, adrenaline and tetracaine, with or without low-dose oral midazolam according to patient's age, to improve the experience of laceration repair. Primary outcomes were improvement of suturing experience for ED operators (as a reduction in the desire to avoid the procedure) and of the adequacy of sedo-analgesia provided, investigated through two different surveys administered to the ED staff before and after the introduction of the SAP. Children's parents were asked about satisfaction with the sedo-analgesia provided. Data were collected prospectively. The analysis included 85 and 60 healthcare professionals involved in the suture of skin wounds in children, respectively before and after the introduction of our SAP. The introduction of the SAP reduced ED operators' stress and improved the entire suturing experience. The pre-post analysis showed a statistically significant improvement in the perceived adequacy of the provided sedo-analgesia (p < 0.0001) and a significant reduction of operators who would have avoided the procedure (p < 0.0001). The great majority of children's parents expressed a high level of satisfaction. The introduction of a LAT gel and low-dose oral midazolam SAP allows an improvement of both the sedo-analgesia provided and the ED operators' suturing experience of skin lacerations in children. Our SAP appeared to be safe and effective, with low cost and high tolerability.

Dekanilacija pri otrocih: predstavitev protokola in naših izkušenj

Background: Tracheostomy increases the morbidity of children, so it is desirable to remove the tracheal cannula (TC) or perform the decannulation as soon as possible. The clinical assessment ensures the child meets the conditions for decannulation. This is followed by decannulation, performed in a hospital environment according to the paediatric decannulation protocol, which guarantees success and safety. The purpose of the study was to analyse the factors influencing decannulation in tracheotomised children and to present the decannulation protocol used at the Department for Otorhinolaryngology and Cervicofacial Surgery of the University Clinical Centre Ljubljana. Methods: Data on tracheotomies and decannulations (age at tracheotomy, indication for tracheotomy, associated diseases, complications of tracheotomy, date of decannulation, and surgical closure of tracheostomy) were retrospectively collected from 43 tracheotomised children. Results: 53.5% (23/43) of children were successfully decannulated (median age = 729.5 days) at a median time of 259.0 days from the tracheotomy. Dysphagia with aspiration was statistically significantly more common among non-decannulated children (p = 0.016) than decannulated children. In the group of decannulated children, the time to decannulation was longer in those under one year of age at the time of tracheotomy (p &lt; 0.001), in those with comorbidities of the lower respiratory tract (p = 0.001 ) or prematurity (p = 0.005). The factor that statistically significantly increased time to decannulation was age at tracheotomy of one year or less (p &lt; 0.001). Conclusion: The paediatric decannulation protocol ensures the successful and safe removal of TC. Dysphagia with aspiration is a common reason for preventing decannulation in children. Risk factors for an increased time to decannulation are age less than one year at tracheotomy, associated lower respiratory tract disease, and prematurity.

Pediatric Esophageal Button Battery Protocol Reduces Time From Presentation to Removal.

Evaluate implementation of an institutional protocol to reduce the time to removal of esophageal button battery (BB) and increase use of mitigation strategies. We developed a protocol for esophageal BB management [Zakai's Protocol (ZP)]. All cases of esophageal BB impaction managed at a tertiary care center before and after implementation from 2011 to 2023 were reviewed. Time to BB removal, adherence to critical steps, and use of mitigation strategies (honey/sucralfate, acetic acid) were evaluated. Fifty-one patients (38 pre-ZP, 13 post-ZP) were included. Median age was 2.3 years (IQR 1.3-3.4). After implementation, the time from arrival at the institution to arrival in the operating room (OR) reduced by 4.2 h [4.6 h (IQR 3.9-6.5) to 0.4 h (IQR 0.3-0.6), p < 0.001] and there was improvement in all management steps. The number of referrals direct to otolaryngology increased from 51% to 92%, arrival notification increased from 86% to 100%, avoidance of second x-ray increased from 63% to 100%, and direct transfer to OR increased from 92% to 100%. Adherence to mitigation strategies such as preoperative administration of honey or sucralfate increased from 0% to 38%, intraoperative use of acetic acid from 3% to 77%, and nasogastric tube insertion from 53% to 92%. Implementation of ZP substantially reduced the time to BB removal and the use of mitigation strategies in our tertiary care institution. Additional strategies focused on prevention of BB ingestion, and shortening the transfer time to the tertiary care hospital are required to prevent erosive complications. 3, Case-series Laryngoscope, 134:5170-5177, 2024.

UK paediatric clinical trial protocols: A review of guidance for participant management and care in the event of premature termination.

Clinical trials provide an opportunity to identify new treatments and can offer patients access to treatments otherwise unavailable. However, approximately 10% of paediatric clinical trials discontinue before the trial has completed. If this premature termination is because the trial treatment(s) being investigated are identified to be ineffective or unsafe, it results in the abrupt discontinuation of the investigational medicinal product for participants. For some participants, there may not be other treatment options to pursue at the trial-end. Trials prematurely terminating can be a distressing experience for all involved and currently there is little published evidence about the guidance provided to healthcare professionals in the event of premature trial termination. The study protocol is the source of guidance for healthcare professionals delivering clinical research, detailing how to conduct all aspects of the trial. The aim was to quantify the proportion of clinical trial protocols that included premature trial termination and subsequently those that provided instructions related to participant management and care. In addition, to analyse the context in which premature termination was included and the detail of any instructions for participant management and care. The ClinicalTrials.gov database was searched by a single reviewer for UK interventional drug trials enrolling children with an available study protocol. Protocols were searched to assess if the risk of premature trial termination was identified, the context for premature termination being included, if information was provided to support the management and care of participants should this situation occur and the detail of those instructions. Data were summarised descriptively. Of 245 clinical trial protocols, 235 (95.9%) identified the possibility of premature trial termination, the majority within the context of the sponsor asserting their right to terminate the trial (82.7%, 115/235) and providing reasons why the trial could be stopped (65.5%, 91/235). Forty-two percent (98/235) provided guidance for participant management and care, most commonly to contact/inform the participant (45.9%, 45/98). Directions varied in the quantity and level of detail. This review of UK clinical trial protocol highlights that information surrounding premature termination is lacking, with only 42% providing guidance on the care of trial participants. While this ensures regulatory compliance, it fails to consider the challenge for healthcare professionals in managing participants on-going care or the duty of care owed to participants. Further research is required to understand if additional documents are being used in practice, and if these meet the needs of healthcare professionals in supporting research participants and families during premature trial termination.

Cluster randomized trial of a team communication training implementation strategy for depression screening in a pediatric healthcare system: a study protocol

BackgroundPediatric depression is a global concern that has fueled efforts for enhanced detection and treatment engagement. As one example, the US Preventive Services Task Force recommends depression screening for adolescents ages 12–18 years. While many health systems have implemented components of depression screening protocols, there is limited evidence of effective follow-up for pediatric depression. A key barrier is timely team communication and coordination across clinicians and staff within and across service areas for prompt service linkage. However, team effectiveness interventions have been shown to improve team processes and outcomes and can be applied in healthcare settings.MethodsThis project aims to refine and test a team communication training implementation strategy to improve implementation of an existing pediatric depression screening protocol in a large pediatric healthcare system. The team will be defined as part of the study but is expected to include medical assistants, nurses, physicians, and behavioral health clinicians within and across departments. The implementation strategy will target team mechanisms at the team-level (i.e., intra-organizational alignment and implementation climate) and team member-level (i.e., communication, coordination, psychological safety, and shared cognition). First, the project will use mixed methods to refine the team training strategy to fit the organizational context and workflows. Next, a hybrid type 3 implementation-effectiveness pilot trial will assess the initial effectiveness of the team communication training (implementation strategy) paired with the current universal depression screening protocol (clinical intervention) on implementation outcomes (i.e., feasibility, acceptability, appropriateness, workflow efficiency) and clinical/services outcomes (increased frequency of needed screening and reduced time to service linkage). Finally, the study will assess mechanisms at the team and team member levels that may affect implementation outcomes.DiscussionTeam communication training is hypothesized to lead to improved, efficient, and effective decision-making to increase the compliance with depression screening and timely service linkage. Findings are expected to yield better understanding and examples of how to optimize team communication to improve efficiency and effectiveness in the pediatric depression screening-to-treatment cascade. This should also culminate in improved implementation outcomes including patient engagement critical to address the youth mental health crisis.Trial registrationNCT06527196.Trial Sponsor: University of California San Diego.

Pediatric Trauma Management in Switzerland: Insights from a Nationwide Survey.

To explore and analyze pediatric trauma care practices across designated pediatric trauma centers (PTCs) in Switzerland. The focus is on reception, trauma team activation (TTA), trauma team composition, patient volumes, and infrastructure. A national online survey was conducted among all eight PTCs in Switzerland with an 18- item questionnaire. The survey investigated organizational aspects, criteria for TTA, patient volume, and communication modalities in pediatric emergency departments (PEDs). All PTCs responded, revealing varied methods of TTA, and with reception of major trauma either within PEDs or at adjacent adult trauma facilities. Trauma team composition and activation criteria also differ among centers, with nonsurgeons often leading the teams and anesthesia as a default for airway management. TTA criteria vary widely, with the most common being the request of prehospital crew (62.5%) and physician discretion (50%). Trauma resuscitation is predominantly led by PED attendings (75%). The survey provides insights into the state of pediatric trauma care in Switzerland and emphasizes the importance of multidisciplinary teams and the variability in trauma management practices, which are often tailored to local circumstances. Despite the limitations of self-reported data and the small sample size due to the country's size, the results suggest that a national trauma registry would help to evaluate and optimize pediatric trauma care protocols.

Effective Pediatric Blood Management in Craniosynostosis Surgery: A Long-Term Update.

Blood transfusion is common in cranial vault surgery, and protocolized efforts to minimize transfusion have been reported in recent years. This study assesses the long term, prospective outcomes of a pediatric blood management protocol for the cranial vault reconstruction (CVR) population. Data from a retrospective control cohort and a prospective cohort employing a protocol for preoperative hematologic optimization of patients undergoing CVR from January 2015 to October 2023 was reviewed. Preoperative hemoglobin (Hgb) determined the preoperative protocol. Intraoperative tranexamic acid (TXA) and/or aminocaproic acid, cell-saver technology, and postoperative iron or erythropoietin alfa supplementation were also used in the protocol. For statistical analysis, P<0.05 was deemed significant. The cohort consisted of 194 successive patients (20 control and 174 treatment). Age, sex, and weight were not significantly different between groups. Mean postoperative Hgb was significantly higher in the control group (P<0.01). No difference was observed in Hgb at discharge between control and treatment groups. Mean estimated blood loss, volume of intraoperative packed red blood cells, rate of packed red blood cell transfusion, and mean total transfusion volume during hospitalization were significantly higher in the control group compared with the treatment group (P<0.01). Mean length of stay did not differ between groups. Efforts to optimize blood management in the CVR population are critical. This prospective study represents a robust and reproducible protocol for pediatric blood management with significant reductions in transfusion requirements.

Multicentric Pediatric Stroke Code: Insight to the first years after implementation

BackgroundThe development of unicentric pediatric acute stroke protocols has improved stroke diagnosis and treatment. The impact of the implementation of a multicentric Pediatric Stroke Code (PSC) remains unknown. Aimto describe the characteristics of the PSC activations and identify clinical features associated with stroke compared to stroke mimics in children in whom a multicentric PSC had been activated and compare them to reported monocentric PSC results. MethodsObservational, retrospective, case and control multicentric study, performed in the Pediatric Emergency Department (PED) of the three Primary Pediatric Stroke Centers (PPSCs) in Madrid (Spain). Study population corresponded to children between 28 days and 16 years old in whom PSC was activated that consulted or were referred to any of the PPSC PED between March 2019 and June 2022. The main outcome was to compare the characteristics of patients with final diagnosis of stroke versus stroke mimics, among all patients for which PSC had been activated. Logistic regression modeling was used to investigate associations between independent variables and stroke diagnosis. Odds ratio (ORs) and 95 % confidence intervals (95%CIs) were estimated. ResultsPSC was activated in 196 patients. Stroke was confirmed in 39 patients (19.9 %): 20 (10.2 %) had an ischemic stroke and 19 (9.7 %) a hemorrhagic stroke. Stroke mimics represented 80.1 % of the PSC activations. Migraine was the most frequent stroke mimic (38.3 %). Time from symptom onset to brain imaging was 233.00 min (IQR 153.00–373.00) when patients self-presented at the PPSC compared to 231.00 min (IQR 129.00–400.00) when PSC was triggered at other settings (p0.580). Five patients (25.3 %) were eligible for hyperacute recanalization treatment. Low level of consciousness (OR4.373, 95%IC 0.247–0.652, p < 0.001), sensory disruption/motor disability of face/limbs (OR3.633, 95%IC 0.103–0.349, p < 0.001), aphasia (OR2.311, 95%IC 0.023–0.284, p0.022) and altered mental status (OR2.517, 95%IC 0.043–0.357, p0.013) were associated with an increased probability of stroke. Conclusionmulticentric PSC achieved similar results to previously reported unicentric PSCs, showing the feasibility of such an organization.

Fact or Fiction-Accelerometry Versus Self-Report in Adherence to Pediatric Concussion Protocols: Prospective Longitudinal Cohort Study.

Concussion, or mild traumatic brain injury, is a growing public health concern, affecting approximately 1.2% of the population annually. Among children aged 1-17 years, concussion had the highest weighted prevalence compared to other injury types, highlighting the importance of addressing this issue among the youth population. This study aimed to assess adherence to Return to Activity (RTA) protocols among youth with concussion and to determine if better adherence affected time to recovery and the rate of reinjury. Children and youth (N=139) aged 5-18 years with concussion were recruited. Self-reported symptoms and protocol stage of recovery were monitored every 48 hours until symptom resolution was achieved. Daily accelerometry was assessed with the ActiGraph. Data were collected to evaluate adherence to the RTA protocol based on physical activity cutoff points corresponding to RTA stages. Participants were evaluated using a battery of physical, cognitive, and behavioral measures at recruitment, upon symptom resolution, and 3 months post symptom resolution. For RTA stage 1, a total of 13% of participants were adherent based on accelerometry, whereas 11% and 34% of participants were adherent for stage 2 and 3, respectively. The median time to symptom resolution was 13 days for participants who were subjectively reported adherent to the RTA protocol and 20 days for those who were subjectively reported as nonadherent (P=.03). No significant agreement was found between self-report of adherence and objective actigraphy adherence to the RTA protocol as well as to other clinical outcomes, such as depression, quality of life, and balance. The rate of reinjury among the entire cohort was 2% (n=3). Overall, adherence to staged protocols post concussion was minimal when assessed with accelerometers, but adherence was higher by self-report. More physical activity restrictions, as specified in the RTA protocol, resulted in lower adherence. Although objective adherence was low, reinjury rate was lower than expected, suggesting a protective effect of being monitored and increased youth awareness of protocols. The results of this study support the move to less restrictive protocols and earlier resumption of daily activities that have since been implemented in more recent protocols.

7663 Inheritable Forms of Differentiated Thyroid Cancer in a Predominantly Hispanic Pediatric Population

Abstract Disclosure: E.A. Delgado: None. A. Martinez: None. N. Solano: None. D. Baboun: None. C. Brathwaite: None. F. Alkhoury: None. C.L. Bustamante Escobar: None. A. Carrillo-Iregui: None. Background: PTEN Hamartoma Syndrome (PHTS) and DICER1 Syndrome are uncommon hereditary conditions causing benign and malignant tumors. Patients exhibiting DICER1 mutation have 5.3% likelihood of developing a tumor before reaching the age of 10, rising to 31.5% by 60. In PHTS, 75% face thyroid issues, with a 21%-38% thyroid carcinoma risk. Pediatric surveillance protocol data is scant; thus, gathering comprehensive data is vital for early tumor detection and management. Objective: Our aim is to determine the prevalence of the hereditary genetic syndromes DICER1 and PTEN associated with differentiated thyroid cancer (DTC) in a predominantly Hispanic pediatric population. This research addresses a knowledge gap in an underrepresented demographic, with the goal of improving diagnosis and management. Methods: Following approval from the Institutional Review Board, we conducted a retrospective examination of medical records from 2012 to 2023, focusing on 213 patients who underwent Ultrasound-Guided Fine Needle Aspiration (US-FNA) for thyroid nodules. Our analysis includes demographics, histopathological diagnoses, and molecular screening results. Results: Participants were predominantly Hispanic children (80%) ranging in age range from 8 to 18 years. The mean age at diagnosis was 15 years (SD± 2.49). Molecular biomarkers for thyroid disease were available in 57 of the 213 patients studied. The predominant genetic mutations identified were BRAF V600E (n=17, 30%), and RET (n=8, 14%), with PTEN showing positivity in 8.7% (n=5) and DICER1 positivity in 12.2% (n=7) of the cases. The analysis identified DTC in 64.9% (n=37) out of the total cohort with molecular markers. Subgroup analysis revealed that within the PTEN-positive subgroup, 20% developed papillary thyroid cancer, while the DICER1-positive subgroup exhibited a 14% incidence of the same cancer type. Inherited forms of thyroid cancer (DICER1 and PTEN) collectively contributed to 5.4% of DTC in our study population. Conclusion: Existing research has indicated inheritable thyroid cancer makes up around 5% of pediatric DTC. Our Hispanic-focused data aligns with prior research in broader populations, reporting low but still significant prevalence of inheritable conditions in thyroid nodules in children and adolescents, The reported cases underscore the significance of screening individuals with thyroid abnormalities for genetic mutations. Additionally, screening individuals with previously diagnosed inherited cancer syndromes for thyroid abnormalities is crucial. Future studies conducted on larger cohorts should investigate the prevalence of inheritable thyroid cancer conditions for further recommendations in surveillance strategies for children or adolescents with genetic mutations such as PTEN and DICER1.

Comparison between the intraoperative CT O-arm and C-arm related to radiation dose and accuracy in scoliosis surgery: A review study

Pedicle screw placement is a vital scoliosis therapy operation that aims to address spinal abnormalities while avoiding consequences including neurological damage caused by misplaced screws. Accurate imaging is required for precise screw insertion, with intraoperative CT (O-arm) and fluoroscopy (C-arm) being the principal modalities used. This review assesses various modalities based on their radiation dosages and accuracy. It comprises research published between 2012 and 2020 that evaluates both effective dose and accuracy for pediatric and adult patients. According to the review, the O-arm outperforms the C-arm in terms of accuracy, resulting in shorter procedure times for both pediatric and adult patients. The O-arm's sophisticated 3-D imaging capacity enhances screw insertion accuracy, reducing the likelihood of problems and the need for additional procedures. Furthermore, using pediatric low-dose protocols and techniques like the Detachable Pedicle Marker and Probe (DPMPs) with pulsed fluoroscopy can reduce radiation exposure while still ensuring precise screw placement. The review suggests that the O-arm has considerable advantages over the C-arm, such as improved image quality and lower radiation risk. This leads to enhanced patient safety and procedural outcomes. Overall, the O-arm's capacity to produce high-quality 3-D pictures makes it an invaluable tool in pedicle screw insertion, resulting in more accurate surgical outcomes and reducing the risk of problems associated with spinal deformity repairs.

Cost-Benefit Analysis of a Pediatric ICU Sedation Weaning Protocol.

A risk stratified sedation weaning protocol improved patient outcomes in a pediatric intensive care unit (PICU). We sought to determine the protocol effect on medication costs. This was a retrospective observational cohort study in an academic tertiary care children's hospital PICU (2018-2020) comparing the cost when weaning benzodiazepine, alpha agonist, and/or opioid infusions in intubated children <18 years of age. There were 84 total sedation weaning instances (pre-protocol n = 41 and post-protocol n = 41); 2 patients had 2 encounters, 1 in each phase. The total cost (in 2022 United States Dollars) of sedation weaning was $400,328.87 ($15,994.44/kg) pre-protocol compared with $170,458.85 ($11,227.52/kg) post-protocol. The median cost of sedation wean per patient for pre-protocol patients was $3197.42 (IQR: $322.66-$12,643.29) and post-protocol patients was $1851.44 (IQR: $425.05-$5355.85; p = 0.275). A linear regression model estimated the expected cost of sedation wean for post-protocol patients to be $5173.20 lower than for pre-protocol patients of the same weight and overall drug risk (p = 0.036). The proportion of withdrawal symptoms in the pre-protocol patients (16%) was not significantly different from the proportion in the post-protocol patients (14%; p = 0.435). Implementation of a PICU sedation weaning protocol in a single-center conferred cost benefit without negatively impacting patient outcomes. A larger multicenter study would provide insight to the applicability to PICUs in varied settings with differing patient populations.

Predictors of Conservative Management Failure in Pediatric Renal Trauma: National Trauma Database Insights

Aim of the studyThis study aimed to evaluate contemporary management strategies of pediatric renal trauma, focusing on the failure of conservative management and identifying its predictors. MethodsThe National Trauma Database (2018–2021) was queried for pediatric patients (≤18 years) with renal injury, identified via AIS codes aligned with the AAST kidney injury grading system. Urological surgical procedures were identified via ICD-10 Procedure Codes. Patients were categorized into immediate surgical management (within 4 h), conservative management (no surgery), and failed conservative management (surgery after 4 h). Demographics, injury characteristics, and clinical data were analyzed using descriptive and univariate statistical analyses (Wilcoxon Rank Sum, Chi-square, Odds Ratios). ResultsOf 7266 pediatric renal trauma patients, most were white (63.4 %) males (69.1 %), aged 12–18 (76.6 %), suffering from unintentional blunt trauma (86.9 %). Most (n = 6610, 95 %) received conservative management; however, 4.5 % (n = 298) failed. Common surgical interventions included ureteral stent placement (n = 200, 59 %), renal IR procedures (n = 44, 13 %), and nephrectomy (n = 33, 9.7 %). Nephrectomy rates at low AAST kidney injury grades (I–II) were higher with upfront surgical management (n = 7, 3.5 %) than with failed conservative management (n = 0). Predictors of failed conservative management included higher Injury Severity Score (ISS) and higher AAST kidney injury grades (III–V) (p < 0.05). ConclusionConservative management failed in 4.5 % of paediatric renal trauma cases, associated with higher AAST kidney injury grade and ISS. Upfront surgical management correlated with a higher nephrectomy rate at lower injury grades compared to failed conservative management. Refinement of pediatric trauma protocols is needed for optimal care. Level of EvidenceIII.

Paediatric computed tomography diagnostic reference levels in Africa: A systematic review.

Improvements in computed tomography (CT) technology in terms of image quality and reduction in absorbed dose have increased its applications in medical imaging. Diagnostic reference levels (DRLs) help to identify high radiation doses that are unusually delivered to patients undergoing exposure to ionising radiation. The aim of this review was to provide an overview of published studies by African researchers towards establishing paediatric CT DRLs in Africa. The search for articles was conducted using some relevant literature search engines including PubMed, Scopus, Science Direct, Google Scholar and Web of Science. Two reviewers were involved in the article selection process which involved a three-stage screening process of identifying; article titles, abstracts and full-test reading. One hundred and seventy-four articles were identified from the database, PubMed (30), Scopus (21), Google Scholar (53), Web of Science (25) and Science Direct (45). Fifty duplicated articles were excluded before screening. Twelve peer-reviewed articles were included in this study based on the inclusion criteria. DRL values in terms of computed tomography dose index volume of head for the age groupings 0-1, 1-5, 5-10 and 10-15 were 27, 36.6, 39.5 and 47.5 mGy while the dose length product values were 461.6, 664, 872 and 978 mGy.cm respectively. The DRLs were calculated as 75th percentile of the local DRLs reported by the 12 articles included in this review. This review has shown that only few of the African countries (19%) have published studies on paediatric CT DRLs. There were variations in the DRLs published by the various authors which indicate that harmonisation and standardisation of paediatric CT protocols is essential for the optimisation of paediatric doses.

Survey of pediatric massive transfusion protocol practice at United States level I trauma centers: An AABB Pediatric Transfusion Medicine Subsection study.

Trauma remains the leading cause of pediatric mortality in the United States. Although use of massive transfusion protocols (MTPs) in this population is widespread, optimal pediatric resuscitation is not well established. We sought to assess contemporary pediatric MTP practice in the United States. A web-based survey was designed by the Association for the Advancement of Blood & Biotherapies (AABB) Pediatric Transfusion Medicine Subsection and distributed to select American College of Surgeons (ACS) Level I Verified pediatric trauma centers. The survey assessed current MTP policy, implementation, and recent changes in practice. Response rate was 55% (22/40). Almost half of the respondents were from the South. The median RBC:plasma ratio was 1 (interquartile range 1-1.5). Protocolized fibrinogen supplementation was common while integration of antifibrinolytic therapy into MTPs was infrequent. Viscoelastic testing (VET) was available at most sites, 71% (15/21, one site did not respond), and was generally utilized on an ad-hoc basis. Roughly, a third of sites had changed their MTP in the past 3 years due to blood supply issues, and about a third reported having group O Whole Blood on-site. MTP practice is similar throughout the United States. Though fibrinogen supplementation is common-other emerging interventions such as antifibrinolytic therapy or utilization of routine viscoelastic testing-are not widespread. Pediatric transfusion medicine experts must continue to follow practice change, as contemporary large trials begin to characterize new supportive modalities to optimize resuscitation in pediatric trauma patients.
