1. Noninvasive Neuromonitoring in Pediatric Traumatic Brain Injury: A Scoping Review of Quantitative Pupillometry and the Evidence Gap in Noninvasive Intracranial Pressure Waveform Analysis.
This scoping review searched five databases through Feb 2026 and identified six pediatric studies — all on quantitative pupillometry using NeurOptics devices. Studies showed time-dependent pupillary light reflex changes after concussion and an inverse correlation between ICP ≥20 mmHg and pupillometry metrics. No pediatric clinical studies evaluated noninvasive ICP waveform morphology (P1/P2/P3) devices, highlighting a primary evidence gap.
Impact: Identifies a high-priority clinical evidence gap (noninvasive ICP waveform monitoring) in children and synthesizes the limited pediatric data on pupillometry, guiding urgent research priorities and device evaluation.
Clinical Implications: Quantitative pupillometry may support triage and correlate with raised ICP, but lack of age-stratified norms, standardized protocols, and outcome studies precludes routine replacement of invasive monitoring; prospective pediatric studies of noninvasive ICP waveform devices are needed before clinical adoption.
Key Findings
- Six pediatric studies met criteria; all investigated quantitative pupillometry using NeurOptics devices.
- Time-dependent alterations in pupillary light reflex observed after concussion; pupillometry parameters inversely correlated with ICP at ≥20 mmHg in one ICU study.
- No primary pediatric clinical studies assessed noninvasive ICP waveform morphology (P1/P2/P3), marking a key evidence gap.
Methodological Strengths
- JBI scoping review methodology and PRISMA-ScR reporting.
- Comprehensive search across five major databases through Feb 2026.
Limitations
- Only six studies and heterogeneous protocols limit generalizability.
- All studies used a single device family (NeurOptics), limiting device-agnostic conclusions.
Future Directions: Prospective, age-stratified multicenter pediatric studies needed to validate pupillometry normative values and to evaluate noninvasive ICP waveform devices (P1/P2/P3 analyses) against invasive ICP and clinical outcomes.
Pediatric traumatic brain injury (TBI) is the leading cause of injury-related death and long-term disability in children worldwide. Current monitoring relies predominantly on invasive techniques that carry procedural risks and are not feasible in all settings or across all severity levels. Noninvasive alternatives, including quantitative automated pupillometry and intracranial pressure (ICP) pulse waveform monitoring, have emerged as promising tools, yet their evidence base in pediatric TBI remains uncharacterized. We conducted a scoping review following the Joanna Briggs Institute methodology, reported per Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews, to characterize existing evidence on these two modalities, examining devices, populations, parameters, and key findings.
2. Mapping intensive care across Ibero-America: The FEPIMCTI multinational survey of bed capacity, workforce, and pandemic response.
Multinational cross-sectional survey across 21 Ibero-American countries covering 693.6 million people reported 78,723 ICU beds (median 6.1/100,000; population-weighted 11.3/100,000) and 23,803 intensivists (median 2.6/100,000). Pandemic surge increased ICU capacity by 69% and physician involvement by 32%, mainly via redeployment rather than certified workforce growth.
Impact: Provides the first coordinated regional benchmark of ICU capacity and workforce across Ibero-America, informing policy, training, and surge planning at national and regional levels.
Clinical Implications: Highlights countries and regions with critical shortages of ICU beds and intensivists; supports targeted investments in training, staffing models, and surge capacity planning rather than relying solely on temporary redeployment.
Key Findings
- 21 countries participated representing 693.6 million inhabitants; 78,723 ICU beds reported (median 6.1 per 100,000; population-weighted 11.3).
- 23,803 intensivists identified (median 2.6 per 100,000), with five countries below 1 per 100,000.
- During COVID-19, ICU bed capacity rose 69% and physician involvement rose 32%, primarily through redeployment of non-intensivists rather than certified workforce expansion.
Methodological Strengths
- Multinational coverage with standardized country-level reporting via national society representatives.
- Large population coverage (693.6 million) and clear pre/post pandemic comparisons.
Limitations
- Cross-sectional national-representative reporting may mask within-country regional heterogeneity and facility-level variation.
- Data rely on self-report by society representatives; potential for reporting bias and differing definitions across countries.
Future Directions: Facility-level standardized data collection, longitudinal workforce tracking, and intervention studies to evaluate training/ staffing strategies and their impact on outcomes are needed.
BACKGROUND: Intensive care resources are unequally distributed across Ibero-America, and reliable comparable data are scarce, hindering cross-national comparison and health-system planning. METHODS: We conducted a cross-sectional survey of the 25 national critical care societies affiliated with FEPIMCTI. Presidents or designated representatives reported country-level data on ICU beds, intensivist and nursing workforce, organizational models, training pathways, and surge capacity before and during the COVID-19 pandemic. Resource density was summarized as the country-level median with IQR and as the population-weighted regional rate. RESULTS: Twenty-one countries, including Spain and Portugal, participated, representing 693.6 million inhabitants. A total of 78,723 ICU beds were reported (country-level median 6.1 per 100,000, IQR 3.3-12.4; population-weighted rate 11.3), with public ICUs accounting for 51.6%. A total of 23,803 intensivists were identified (median 2.6 per 100,000, IQR 1.0-5.0), with five countries below 1 per 100,000. Nurse-to-patient ratios ranged from 1:1 to 1:7, and universal 24/7 intensivist coverage was reported in only a subset of countries. During the pandemic, ICU bed capacity rose 69%; among the 20 countries with data for both periods, physician involvement rose 32%, largely through redeployment of non-intensivists rather than growth of the certified workforce. CONCLUSIONS: Critical care capacity, workforce, and organization vary widely across Ibero-America, with many countries below high-income benchmarks and pandemic surges met largely through temporary redeployment. These findings provide the first coordinated regional benchmark to guide workforce development, standardized training, and organizational strengthening.
3. Postoperative Oral Dexamethasone and Pediatric Tonsillectomy Morbidity: A Randomized Clinical Trial.
In a quadruple-blind RCT of children undergoing adenotonsillectomy, postoperative oral dexamethasone given on days 2, 4, and 6 was associated with a modest reduction in mean pain scores and notably fewer opioid prescriptions and ED visits for pain, without increased complications. Differences in early pain had wide CIs, but later time points (days 12–13) showed clearer reductions.
Impact: High-quality randomized evidence supports a simple, low-cost postoperative regimen that reduces opioid exposure in children, a key stewardship target, without added harm.
Clinical Implications: Consider adding oral dexamethasone (0.5 mg/kg, max 20 mg) on postoperative days 2, 4, and 6 after pediatric adenotonsillectomy to modestly reduce pain and meaningfully curb opioid prescribing, with careful counseling about benefits and limited evidence precision for early pain.
Key Findings
- Mean pre-analgesic pain during days 2–8 was 0.72 points lower with dexamethasone versus placebo, with wide 95% CIs.
- Dexamethasone reduced pain on postoperative days 12–13 by 0.96–2.37 points.
- Opioid prescription odds were markedly reduced (OR 0.23; 95% CI 0.06–0.84) and ED visits for pain decreased (OR 0.12; 95% CI 0.003–0.91).
- No meaningful differences in complications (e.g., hemorrhage) or return to normal diet.
Methodological Strengths
- Quadruple-blinded, randomized design with prespecified outcomes
- Real-world relevant endpoints (pain, opioid prescribing, ED visits) and safety follow-up
Limitations
- Single-center with incomplete pain diary completion (primary analysis n=131)
- Wide confidence intervals for early pain differences limit precision
Future Directions: Multicenter confirmatory RCTs powered for pain trajectories and opioid-sparing outcomes; exploration of dosing schedules and generalizability across surgical populations.
IMPORTANCE: Tonsillectomy is among the most painful otolaryngologic procedures. It is unclear whether a postoperative course of oral steroids reduces pediatric tonsillectomy pain and morbidity. OBJECTIVE: To determine whether a postoperative course of oral dexamethasone reduces postadenotonsillectomy pain in children. DESIGN, SETTING, AND PARTICIPANTS: This was a parallel-design quadruple-blinded randomized clinical trial conducted at a single tertiary academic center that enrolled pediatric patients (3-17 years of age) undergoing adenotonsillectomy from August 2021 to May 2023, with 14 days of follow-up for pain and 5 to 9 weeks for adverse events. Data were analyzed from October 2023 to May 2026. INTERVENTION: Oral dexamethasone (0.5 mg/kg; maximum dose, 20 mg) or placebo on postoperative days 2, 4, and 6.
