Safety and Efficacy of Intranasal Ketamine for Minor Pediatric Procedures: A Systemic Literature Review.

Compared to intravenous anesthetics, intranasalmedication for sedation is a less invasive approach. Intranasal ketamine (IK) is a widely used medication for procedural sedation. Hence, a systematic review was conducted with the aim of evaluating the safety and efficacy of IK among pediatric patients used for procedural sedation. For this purpose, a literature search was conducted on PubMed, Web of Science, and MEDLINE. A total of 247 search results appeared after running the developed query andeight articles passed through the inclusion and exclusion criteria and were included in the study. Most of the studies used 4 to 7 mg/kg dose of IK for pediatric patients. It was found that there was a moderate correlation between the age and dose of IK. Similarly, the dose of IK also had a direct and moderate correlation with the onset of sedation. Regarding the reported side effects, most of the studies reported nausea and vomiting as side effects of IK. Hence, it could be concluded from the study findings that effective sedation can be achieved by using 4 to 7 mg/kg dose of IK. The reported side effects ofIK were minor while parental satisfaction with the drug was very high. Therefore, it can be concluded that the use of IK for procedural sedation among pediatric patients is safe and effective.

Comparison of Long-Term Clinical Outcomes and Costs Between Transesophageal Echocardiography-Guided and X-ray-Guided Percutaneous Atrial Septal Defect Closure in Children.

This study aimed to compare the long-term clinical outcomes and costs between using either transesophageal echocardiography (TEE) or X-ray fluoroscopy for Percutaneous atrial septal defect (ASD) closure in children. An analysis was conducted on clinical data from children undergoing TEE-guided (n = 168) and X-ray-guided (n = 139) percutaneous ASD closure. Demographic characteristics, technical indices, acute complications, follow-up outcomes, and costs were compared between the groups. The results are that TEE-guided closure demonstrated shorter surgical times (20.3 ± 7.6min vs. 32.8 ± 7.9min, P < 0.001) and lower procedural costs ($3093.3 ± 451.5 vs. $3589.1 ± 219.4, P < 0.001) compared to X-ray guidance. Initial successful closure rates were similar between the groups (TEE: 98.2%, XR: 97.1%, P = 0.691). TEE guidance also resulted in fewer acute complications and reduced radiation exposure. TEE-guided percutaneous ASD closure offers advantages in terms of shorter surgical times, lower procedural costs, and reduced radiation exposure compared to X-ray guidance. These findings support the preference for TEE guidance in pediatric ASD closure procedures, with potential implications for improving patient outcomes and reducing healthcare costs.

Evaluation of Noise Exposure Levels in Pediatric ENT Operating Rooms.

Operating room (OR) sounds may surpass noise exposure thresholds and induce hearing loss. Noise intensity emitted by various surgical instruments during common pediatric otolaryngologic procedures were compared at the ear-level of the surgeon and patient to evaluate the need for quality improvement measures. Cross-sectional study. Single tertiary care center. Noise levels were measured using the RISEPRO Sound Level Meter and SoundMeter X 10.0.4 at the ear level of surgeon and patient every 5minutes. Operative procedure and instrument type were recorded. Measured noise levels were compared against ambient noise levels and the Apple Watch Noise application. Two hundred forty-two total occasions of noise were recorded across 62 surgical cases. Cochlear implantation surgery produces the loudest case at the ear-level of the patient (91.8Lq Peak dB; P < .001). The otologic drill was the loudest instrument for the patient (92.1Lq Peak dB; P < .001), while the powered microdebrider was the loudest instrument for the surgeon (90.7Lq Peak dB; P = .036). Noise measurements between surgeon and patient were similar (P < .05). Overall agreement between the Noise application and Sound Level Meter was excellent (intraclass correlation coefficient of 0.8, with a 95% confidence interval ranging from 0.32 to 0.92). Otolaryngology OR noises can surpass normal safe thresholds. Failure to be aware of this may unwittingly expose providers to noise-related hearing loss. Mitigation strategies should be employed. Quality improvement measures, including attention to surgical instrument volume settings and periodic decibel measurements with sound applications, can promote long-term hearing conservation. Otolaryngology OR noises can surpass normal safe thresholds. Failure to be aware of this may unwittingly expose providers to noise-related hearing loss. The duration, frequency of exposure, and volume levels of noise should be studied further. Mitigation strategies should be employed. Quality improvement measures, including attention to surgical instrument volume settings and periodic decibel measurements with sound applications, can promote long-term hearing conservation.

The impact of audiovisual information on parental anxiety levels prior to hypospadias surgery: A prospective single center cohort study

Most parents have anxiety before a pediatric surgical procedure. Parental anxiety may impair the parents' ability to cope with new or stressful situations while their children are undergoing surgery. By effectively improving the education of parents regarding the diagnosis, treatment, and potential complications of hypospadias and surgical repair, it might be feasible to reduce their anxiety during this process. To determine whether structured audiovisual information would reduce parents' anxiety levels compared to classic verbal information. The diagnosis was made and, treatment options were explained, and State-Trait Anxiety Inventory Form - State Anxiety (STAI-I) forms were filled out by parents at the first consultation. In the second consultation, parents were divided into structured audio-visual-information (Group-1) and classic verbal information (Group-2) groups. Following these consultations, all parents in both groups filled out STAI-I again. Parents filled out the forms for the last time on the postoperative-14th-day and the results were compared. A total of 124 (51.2%) parents were informed with structured-audiovisual-informational material and 118 parents (48.8%) were informed with classic verbal information. First STAI-I scores were 57.65±5.17 and 56.91±5.28 for Group-1 and Group-2, respectively, and there was no difference between the groups (p=0.709). The STAI-I scores after the second consultation were 44.82±5.65 and 49.42±2.81 for Group-1 and Group-2, respectively. Parental anxiety decreased in both groups following the second consultation. Notably, a statistically significant superiority was found between the groups in favor of Group-1 (p=0.001). Parents whose children will undergo hypospadias surgery experience significant anxiety. We observed that informing patients adequately and in appropriate language using a suitable method was associated with less anxiety. Preoperative parental anxiety is influenced by several variables, including parent age, parent gender, child age, lack of knowledge, and concerns over complications or pain. Although we are unable to alter the factors of child age and parent gender, we can impact parents' concerns regarding postoperative pain and anesthesia by enhancing their comprehension of the procedure via providing them of sufficient and accurate information. Providing parents with structured audio-visual information about the preoperative and postoperative period before hypospadias surgery is associated with lower parental anxiety levels. Supplying structured audiovisual information regarding the preoperative and postoperative periods can help parents have an improved comprehension of the procedure and minimize their anxiety.

Paediatric patient referrals from Greenland to the National University Hospital, Rigshospitalet, Denmark.

Greenlandic patients may be referred to Denmark for specialised diagnostics and treatment. The main collaborator for these activities is the National University Hospital, Rigshospitalet, Copenhagen. We aimed to investigate the referral pattern of Greenlandic paediatric patients to Rigshospitalet. This was an observational quality assurance project comprising all Greenlandic patients below 18 years who received healthcare services at Rigshospitalet in the 2017-2021 period. This period was chosen to obtain the most updated, available and coherent data possible. Unique patients and disease courses were stratified by paediatric subspecialities and procedures. During the five-year period, a total of 310 unique patients were referred to Rigshospitalet, resulting in a total of 676 disease courses and yielding an average 62 annual referrals of paediatric Greenlandic patients. This represents around 0.5% of all Greenlandic children. Age groups were distributed as 28% aged 0-1 years, 23% 2-4 years, 13% 5-9 years, 21% 10-14 years and 16% 15-17 years. During the study period, the number of disease courses increased by 89% with most patients being managed as outpatients. The subspecialities with most referrals were ophthalmology (17%), oto-rhino-laryngology (16%) and cardiovascular diseases (10%). Approximately 0.5% of Greenlandic children were referred annually to Rigshospitalet with a marked increase being observed during the five-year study period. We observed a shift towards an increasing proportion of outpatient treatments at Rigshospitalet. None. Not relevant.

Strategies to minimize procedure-related pain and anxiety: lessons from pediatric dermatology.

Recent studies have suggested that prolonged or repeated episodes of general anesthesia early in childhood may adversely affect neurodevelopment. This, combined with rising healthcare costs and decreasing access, has sparked interest in performing pediatric procedures in the office setting when possible. It is essential to address the physical and psychological discomfort that often accompany this experience, particularly in children. Healthcare providers performing procedures on children can draw from a spectrum of established techniques, new technology, and novel use of medications to decrease peri-procedural pain and anxiety. These techniques include distraction, optimization of local anesthesia, and mild to moderate sedation. We recommend using a combination of techniques to minimize pain and anxiety to improve safety, decrease healthcare costs, improve patient experience, and prevent childhood trauma and persistent negative perception of the healthcare system.

Minimal Access in Pediatric Surgery: An Overview on Progress towards Dedicated Instrument Developments and Anesthesiologic Advances to Enhance Safe Completion of Procedures.

Surgical techniques are evolving in Pediatric Surgery, especially in the area of minimal access surgery (MAS) where indications for applications are expanding. Miniaturization of instruments, using natural orifices, single incisions, or remotely controlled robot-assisted procedures, promises to increase the benefits of MAS procedures in pediatrics. Many pediatric pathologies are rare, and specialized surgical and anesthesiologic instruments are necessary to manage them, defined as "orphan devices", for which development and dissemination on the market are slowed down or sometimes hindered by regulatory standards and limiting financial conflicts of interest. In pediatric surgery, it is of utmost importance to work in a multidisciplinary way to offer a surgical path that is safe and supported by technological advances. For this reason, optimizing pediatric anesthesia is also a crucial factor where technological advances have made monitoring more precise, thereby enhancing safety in the operative room. The development of customized instruments and technologies should be supported by pediatric research and should be adapted to the individualities of the small patient. This overview outlines the importance of dedicated instruments developed for the safe completion of MAS procedures in pediatrics.

Application of the ERAS guidelines in pediatric urological surgery: a systematic review.

Consensus for Enhanced Recovery After Surgery (ERAS) in pediatrics has been achieved in neonatal intestinal surgery, yet it is not widely utilized in pediatric urology. We investigated the application of ERAS guidelines in pediatric urology, and determined its effects given the available level of evidence supporting the ERAS protocol in children. A systematic literature review including series providing adoption of fast-track recovery protocols for pediatric urology procedures was carried out. Main outcome measures were study characteristics, adherence to the 19 ERAS items, complication rates and length of hospital stay. Sub-group analysis by surgery type (hypospadias versus major surgery) was performed. Nine series with data from 1272 surgical pediatric cases were included. An enhanced recovery pathway was applied in 67.3% of the reports. Two series included patients undergoing hypospadias repair and ERAS items were insufficiently reported. Studies including children undergoing major procedures mentioned a median of 15 ERAS items, yet applied a median of 11 items. Median compliance rate was 88.9% (range 50-100). More ERAS guideline items were reported (applied or mentioned) in the most recently published studies. There is limited reporting and use of the ERAS guidelines in urologic surgery particularly in hypospadias repair; whilst in major surgery in children, adherence and compliance rates vary widely. In more recent series there was an increase in ERAS items that have been mentioned and applied. Future research is needed to identify barriers and to overcome them in order to fully adopt and benefit from the ERAS pathway.

Effectiveness of Deep Breathing Technique on Pain Level of School Children during Catheterization

Abstract Background: Pediatric medical procedures mostly cause pain and fear among hospitalized children. Many nonpharmacological pain strategies can used to decrease children’s fear and pain in addition to decreasing the burden of medication. Objectives: This study aimed to determine the effectiveness of the deep breathing technique on children's pain intensity during urine catheterization procedures, at Children Welfare Teaching Hospital in Baghdad city. Materials and Methods: A quasi-experimental study was selected to determine the effects of pain strategies through achieving the manipulation and control group, conducted with a nonprobability (convenience) sample of 60 children of both genders at the age range of 6–12 years, divided into three groups of 20 children in each group. The study was carried out at Children Welfare Teaching Hospitals, from the period October 13, 2021, to July 28, 2022. The numeric Pain Rating Scale was used to assess pain level before and after nursing intervention with three pain management methods that included deep breathing technique, pharmacological, and combination methods. Results: The result of the study revealed that the application of deep breathing techniques, pharmacological, and combination methods were effective in reducing children’s pain at different levels. The deep breathing method has a significant influence on reducing children’s pain. The most effective method to reduce children’s pain was a combination method. Conclusion: This study concludes that the application of all pain management methods in this study was effective in reducing children’s pain at different levels during catheterization. The combination method (pharmacological and nonpharmacological) was most effective in reducing children’s pain. However, the deep breathing method approved its significant influence on children’s pain.

What is the impact of simulation-based training for paediatric procedures on patient outcomes, cost and latent safety threats?

Simulation-based training (SBT) provides a safe space for medical trainees to experience realistic scenarios. SBT has been found to improve trainee performance in paediatric procedures. However, limited evidence exists regarding its effects on higher-level outcomes. This scoping review aims to identify studies that investigate the impact of SBT for procedural skills on T3 (patient outcomes) and T4 level outcomes (latent safety threats [LSTs], and hospital level costs) in paediatrics. Full-text articles were included if they focused on medical trainees, used simulation training for paediatric procedures and reported T3/T4 level outcomes. Six databases were searched from January 2011 to September 2022. Search strategies were developed with the assistance of a librarian. Three independent reviewers performed pilot screenings before title/abstract and full-text screenings. A data extraction sheet was created to gather information on interventions, outcomes, research design, and other study characteristics. After title/abstract screening of 4,076 sources, 50 were included for full-text review, with 15 articles selected for data extraction. Four were randomised control studies (RCTs), fourteen focused on T3 level outcomes including mortality rates, and one measured LSTs. There were no studies reporting cost-related data. Three of the studies focused on bag-and-mask ventilation, and eight mentioned the use of mannequins. We highlight the potential effectiveness of simulation-based training of paediatric procedural skills in improving patient outcomes, such as reduced mortality rates and incidence of illness/injury. Though the quality of research designs was low, researchers used different simulation modalities and outcome measures and showed a positive impact of SBT(e.g., decreased mortality rates).

Interventions to Reduce Intra-Operative and Post-Operative Pain Associated with Routine Dental Procedures in Children: A Systematic Review and Meta-Analysis.

implementing appropriate pharmacological and non-pharmacological interventions to alleviate pain related to routine dental procedures in paediatric patients could enhance children's ability to manage dental care. The aim of this review was to investigate the effectiveness of and provide recommendations for interventions that can be used to reduce intra-operative and post-operative pain associated with routine paediatric dental procedures. A systematic review of randomised controlled clinical trials (RCT) was conducted. Multiple electronic databases were systematically searched. The Cochrane risk-of-bias tool for RCTs was used to evaluate the quality of the included studies. A meta-analysis was performed to determine the effectiveness of the interventions using the Cohen's d standardised mean differences (SMD) and 95% confidence intervals (CIs) for continuous outcomes. The GRADE tool was used to assess the certainty of evidence to make recommendations. The review included forty-five RCTs comprising 3093 children. Thirty-seven RCTs were included in the meta-analysis, which showed the effectiveness of behavioural interventions (SMD = -0.50, 95% CI -0.83 to -0.18), mechanoreceptor and thermal receptor stimulation (SMD = -1.38, 95% CI -2.02 to -0.73) for intra-operative pain, and pre-emptive oral analgesics (SMD = -0.77, 95% CI -1.21 to -0.33) for reducing post-operative pain in children receiving routine dental care. The GRADE results for these interventions were strong recommendation (IB) for their use, based on moderate evidence and their benefits far outweighing the harm, and they can be delivered readily with minimal training to reduce the pain experience of paediatric patients.

Advocating for Alignment in Pediatric Cardiothoracic Surgical Site Infection Surveillance Definitions.

Reporting definitions for Surgical Site Infections (SSIs) are frequently used to identify cases for quality improvement purposes. Here we highlight the discrepancies in reporting criteria for pediatric cardiac surgery procedures and call for alignment in definitions.

Virtual reality use in pediatric patients for orthopedic clinical procedures: A randomized prospective trial of efficacy.

Distraction therapy use such as virtual reality is novel in the pediatric orthopedic field. In this study, we use subjective and objective metrics to evaluate virtual reality efficacy to reduce anxiety and pain in a pediatric orthopedic cohort. A prospective randomized controlled trial included patients between age 5 and 17 years, presenting to a tertiary care pediatric orthopedic clinic. Parallel groups underwent orthopedic procedures in clinic, utilizing immersive and interactive virtual reality distraction therapies versus standard of care. Procedures included cast application, cast removal, bone pin removal, and fracture reduction. All preprocedure parameters were similar between the groups. Primary outcome was the difference between maximum procedural heart rate and baseline. Secondary outcomes included Wong Baker FACES Rating Scale (Wong & Baker, 1988, Oklahoma, USA) for pain and Visual Analog Scale scores for anxiety. Ninety-five patients (66 M, 29 F) underwent 59 cast removals, 26 cast applications, 7 percutaneous pin removals, and 3 fracture reductions. Average patient age in the virtual reality and control cohorts was 10.1 (5-17) and 10.6 (5-17), respectively. Average change in maximum heart rate in the virtual reality and control groups was 10.6 ± 10.1 versus 18.4 ± 11.0 (p = 0.00048). The virtual reality group demonstrated trends toward lower perceived anxiety (1.7 ± 2.8 versus 2.9 ± 3.6, p = 0.0666) when compared to controls. This level 1 study is the first to utilize objective biometric measurements to evaluate use of interactive virtual reality during multiple types of pediatric orthopedic procedures in the clinical setting. The findings suggest that an interactive and immersive virtual reality experience can be effective in reducing pain and anxiety. Level 1, Randomized Controlled Trial.

Intravenous ketorolac versus intravenous dexmedetomidine for postoperative analgesia after hypospadias repair

ABSTRACT Hypospadias repair surgery, though necessary, can be painful after the procedure, especially for children. Effective pain management is essential in all surgeries, but particularly in pediatric procedures. The current study was conducted to evaluate the analgesic efficacy of intravenous ketorolac versus dexmedetomidine after hypospadias repair surgery. Patients and methods A total of 60 children aged between 2 and 7 years old undergoing hypospadias repair under general anesthesia enrolled in the study. Those children were randomly divided into either group Ketorolac (group A) or Dexmedetomidine group (group B). Group (A) included 30 patients who received IV ketorolac in a dose 0.9 mg/kg after intubation for general anesthesia while group (B) included 30 patients who received IV dexmedetomidine in a dose 1 μg/kg after intubation. Pain scores (FLACC), sedation and emergence agitation (EA) scores, 1st analgesic dose, hemodynamics, and any side events were recorded. Results The main finding in this study was that group (B) had significantly lower FLACC at different postoperative times compared to group n(A)with p < 0.05; with exception at 4th and 12th hours. It was found that FLACC was zero in group (B) till the 6th hour postoperatively. All patients in the studied groups had sedation scale was 3 starting from the 4th postoperative hour. Immediate and 2-hour postoperatively, the score was significantly higher among the dexmedetomidine group.Two patients developed EA in group A but non in group B. Conclusion Adjuvant intravenous dexmedetomidine is more effective than intravenous ketorolac in postoperative analgesia children after hypospadias repair surgery under general anaesthesia.

P.142 The use of intraoperative magnetic resonance imaging for endoscopic transnasal transsphenoid surgery in children

Background: Sellar and suprasellar pediatric lesions are uncommon. Endoscopic transnasal transphenoidal surgery (ETTS) is the preferred treatment, but early post-op MRI is hindered by sphenoidal packing. This study aims to assess iMRI safety and efficacy in pediatric ETTS cases. Methods: We performed a retrospective review from Jan 01, 2015 to Dec 31, 2022, evaluating use of iMRI. We determined if the goals of the surgery (biopsy, cyst decompression, subtotal resection, gross total resection) were met, and iMRI’s influence on surgery outcomes. We examined patient age, surgery duration, length of stay, histopathology results, surgical complications, post-op MRIs within 1 month, and tumor progression/recurrence. Results: Over eight years, 20 pediatric ETTS procedures, 14 with iMRI, were conducted. Achieving goals in 13 cases, iMRI prompted extra surgery once. Two adenomas progressed, requiring a second surgery, and craniopharyngioma cases had complications, needing further interventions. Hospital stays varied (1-9 days), with a mean surgery duration of 6 hours and 47 minutes. The study underscores iMRI’s potential impact, stressing the necessity for more research in pediatric transsphenoidal surgeries. Conclusions: While intraoperative MRI in pediatric transsphenoidal surgeries may aid goal verification, this small study doesn’t conclusively demonstrate improved outcomes. Complication rates align with non-IMRI procedures, highlighting the need for further research.

Comparing Oral Microbiota Changes after Pulpotomy/Pulpectomy in Pediatric Patients.

Pediatric dental procedures like pulpotomy and pulpectomy are commonly performed to treat pulp-related dental issues in primary teeth. The choice of instrumentation, such as traditional rotary instruments or laser technology, can impact the oral microbiota. This study aims to compare the changes in oral microbiota following pulpotomy/pulpectomy in pediatric patients treated with traditional rotary instruments versus laser technology. A total of 60 pediatric patients, aged 4-10 years, requiring pulpotomy or pulpectomy were randomly assigned to two groups: group A (traditional) and group B (laser). In group A, traditional rotary instruments were used for pulp removal, while in group B, a dental laser was utilized. Saliva and plaque samples were collected before the procedure (baseline), immediately after the procedure, and at the one-month follow-up. Microbial deoxyribonucleic acid (DNA) was extracted and analyzed using 16S ribosomal ribonucleic acid (rRNA) sequencing to assess changes in the oral microbiota. At baseline, both groups exhibited similar microbial diversity and composition. However, immediate post-procedure results showed a significant decrease in microbial diversity in both groups, with group B (laser) demonstrating a more pronounced reduction. At the one-month follow-up, group A (traditional) showed a partial recovery of microbial diversity, while group B (laser) continued to exhibit lower microbial diversity compared to baseline. Notably, group B (laser) displayed a shift in microbial composition with a decrease in pathogenic species and an increase in beneficial bacteria compared to group A. This study highlights that both traditional rotary instruments and laser technology have a significant impact on the oral microbiota of pediatric patients following pulpotomy/pulpectomy. While both methods initially reduce microbial diversity, laser treatment appears to have a more sustained effect, favoring the growth of beneficial bacteria over time. Further research is needed to assess the long-term clinical implications of these microbiota changes for the oral health of pediatric patients.

Incidence of Surgically Managed Post-Tonsillectomy Hemorrhage Associated With NSAID Prescribing for Postoperative Pain Management.

Tonsillectomy ranks high among the most common pediatric surgical procedures in the United States. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), such as ibuprofen, are routinely prescribed to manage post-tonsillectomy pain, but may carry the risk of hemorrhage. This retrospective, longitudinal, secondary-data analysis study compared the incidence of surgically managed post-tonsillectomy hemorrhage (sPTH) in pediatric patients prescribed ibuprofen at Brooke Army Medical Center (BAMC) after tonsillectomy compared to a similar cohort of pediatric patients at the Children's Hospital of Philadelphia (CHOP) not prescribed ibuprofen. Additional regression analysis examined predictors of sPTH at BAMC. The odds of sPTH was lower in patients who were prescribed ibuprofen at BAMC, relative to patients who were not at CHOP (OR 0.57, 95% CI, 0.37, 0.87; P < 0.01). In a generalized linear model evaluating BAMC patient data, there was a lack of a relationship between reason for tonsillectomy (tonsillitis versus tonsillar obstruction), primary procedure (tonsillectomy-only versus tonsillectomy with adenoidectomy), and presence of a co-occurring procedure. Post-tonsillectomy ibuprofen prescribing practices were not associated with an elevated risk of sPTH, relative to patients at CHOP not exposed to ibuprofen.

Trends in Medicare Reimbursement for Common Pediatric Orthopedic Procedures: From 2000 to 2022.

Objective We aimed to evaluate trends in government monetary reimbursement (Medicare) for 10 of the most commonly performed pediatric orthopedic procedures from 2000 to 2020. Methods Utilizing the Centers for Medicare and Medicaid Services website, we collected data for 10 of the most commonly performed pediatric orthopedic surgical procedures and their variations. The reimbursement data for each procedure was taken from the Current Procedural Terminology (CPT) code, which was collected from the Physician Fee Schedule Look-Up Tool from the Centers for Medicare and Medicaid Services (Baltimore County, MD). The reimbursement values were adjusted for inflation to the 2022 US dollar (USD) using the changes to the Consumer Price Index. The compound annual growth rates (CAGRs) and total percentage changes in reimbursement were calculated for all the procedures and put into relative value units. Results Reimbursement for 20 of the 22 total procedures decreased by 32.65% from 2000 to 2022 after adjusting for inflation. Achilles tenotomy with local anesthesia saw the greatest decrease (-54.38%), whereas the procedure revision of spinal fusion saw the highest increase (26.00%) in mean adjusted reimbursement during this study period. Adjusted reimbursement decreased by an average of 2.08% on a yearly basis. Conclusion This study is the first to take an in-depth view and evaluate trends in procedural Medicare reimbursement for pediatric orthopedic surgery. When adjusted for inflation, Medicare reimbursement for 20 of 22 included procedures has steadily decreased from 2000 to 2022. There needs to be an increased awareness and consideration of these trends as they will be important for policymakers, hospitals, and surgeons to ensure continued access to meaningful surgical pediatric orthopedic care in the United States.

Medical staff dose estimation during pediatric cardiac interventional procedures.

The purpose of this study is to evaluate the occupational doses (eye lens, extremities and whole body) in paediatric cardiac interventional and diagnostic catheterization procedures performed in a paediatric reference hospital located in Recife, Pernambuco. For eye lens dosimetry, the results show that the left eye receives a higher dose than the right eye, and there is a small difference between the doses received during diagnostic (D) and therapeutic (T) procedures. The extrapolated annual values for the most exposed eye are close to the annual limit. For doses to the hands, it was observed that in a significant number of procedures (37 out of 45 therapeutic procedures, or 82%) at least one hand of the physician was exposed to the primary beam. During diagnostic procedures, the physician's hand was in the radiation field in 11 of the 17 catheterization procedures (65%). This resulted in a 10-fold increase in dose to the hands. The results underscore the need for optimization of radiation safety and continued efforts to engage staff in a radiation safety culture.
