Summary
Three impactful studies span neonatal risk prediction, pediatric anesthetic pharmacology, and airway training safety. A large multicenter study introduced NeonatalBERT, an LLM that outperformed existing models in predicting neonatal morbidities from clinical notes; a pediatric RCT showed dexmedetomidine shortened rocuronium onset and stabilized intubation hemodynamics; and a randomized training study found supraglottic jet oxygenation and ventilation (SJOV) eliminated hypoxemia and accelerated competency during fiberoptic intubation training.
Research Themes
- LLM-driven neonatal risk stratification from unstructured clinical notes
- Pediatric anesthetic pharmacology and neuromuscular blockade modulation
- Airway management training innovations to prevent hypoxemia
Selected Articles
1. Development and validation of a pre-trained language model for neonatal morbidities: a retrospective, multicentre, prognostic study.
Using 32,321 newborns for primary development and 7,061 for external validation, NeonatalBERT outperformed Bio-ClinicalBERT, BioBERT, and tabular models in predicting 19 neonatal morbidities in the primary cohort (mean AUPRC 0.291 vs 0.238–0.194) and ten morbidities in the external cohort (mean AUPRC 0.360 vs 0.224–0.333). The model leverages unstructured clinical notes to enable earlier, more comprehensive risk estimation.
Impact: This study introduces a validated, domain-specific LLM that consistently improves neonatal morbidity prediction across institutions, opening a path to operational decision support.
Clinical Implications: Potential integration into NICU workflows for proactive monitoring and resource allocation, earlier specialty consultation, and targeted surveillance without additional lab burden.
Key Findings
- In the primary cohort (n=32,321), NeonatalBERT achieved a mean AUPRC of 0.291 (95% CI 0.268–0.314), outperforming Bio-ClinicalBERT (0.238), BioBERT (0.217), and tabular models (0.194).
- In the external cohort (n=7,061), NeonatalBERT maintained superior performance with a mean AUPRC of 0.360 (95% CI 0.328–0.393), exceeding comparators (0.224–0.333).
- Model performance covered 19 neonatal morbidities in the primary cohort and 10 in the external cohort, demonstrating breadth of applicability.
Methodological Strengths
- Large multicenter cohorts with external validation
- Direct benchmarking against domain LLMs and traditional tabular models across multiple outcomes
Limitations
- Retrospective design limits causal inference and may reflect documentation bias
- Generalizability beyond two US academic centers and fairness across subgroups require additional validation
Future Directions: Prospective deployment studies evaluating impact on clinical workflow, outcomes, and equity; integration with structured data and imaging; calibration and drift monitoring at scale.
BACKGROUND: Early identification and monitoring of neonatal morbidities are critical for timely interventions that can prevent complications, optimise resource use, and support families. Although traditional tools based on tabular data and biomarkers are beneficial, they are restricted in assessing the risk of morbidities in newborns. In this study, we developed NeonatalBERT, a pre-trained large language model (LLM) that estimates the risk of neonatal morbidities from clinical notes. METHODS: This prognostic study investigated retrosp
2. Effect of Dexmedetomidine on Rocuronium-Induced Neuromuscular Blockade and Intubation Condition in Children: A Randomized Controlled Trial.
In 60 children randomized to dexmedetomidine (0.5 μg/kg over 10 min) versus placebo before propofol induction, dexmedetomidine reduced rocuronium onset time (177.8 s vs 205 s; p=0.021) without affecting the time to BIS <60. Hemodynamics during intubation (SBP, DBP, MAP, HR) were significantly lower in the dexmedetomidine group, with no differences in intubation attempts or adverse effects.
Impact: Provides randomized, registered evidence that a common adjunct (dexmedetomidine) can modestly accelerate neuromuscular blockade onset and stabilize intubation hemodynamics in children.
Clinical Implications: Pre-induction dexmedetomidine may optimize timing for rocuronium-assisted intubation and blunt sympathetic responses in pediatric patients without increasing adverse events.
Key Findings
- Rocuronium onset time was shorter with dexmedetomidine (177.8 s; 95% CI 161.1–194.0) vs placebo (205 s; 95% CI 188.0–222.0), p=0.021.
- Time for BIS to reach <60 was unaffected (34.3 s vs 33.2 s; p=0.772).
- Intubation hemodynamics were more stable with dexmedetomidine (lower SBP, DBP, MAP, HR at intubation), without differences in intubation attempts or adverse effects.
Methodological Strengths
- Randomized, controlled, registered trial (NCT03923075)
- Objective neuromuscular (TOF) and hypnosis (BIS) measurements with confidence intervals
Limitations
- Single-center study with modest sample size
- Not powered for rare adverse events; details of blinding not described
Future Directions: Larger, multicenter pediatric RCTs assessing varying dexmedetomidine doses, safety (bradycardia/hypotension), and interactions with other neuromuscular blockers and induction agents.
BACKGROUND: Dexmedetomidine is an a MATERIAL AND METHOD: A total of 60 children undergoing elective surgery, ages 4-12 years, were enrolled in the study. Before the induction of anesthesia with propofol, 30 children received dexmedetomidine 0.5 μg/kg given over 10 min (group D). Another group of 30 children received the same volume of N/S 0.9% over 10 min as well (group P). We recorded time to achieve TOF = 0 from the end of rocuronium infusion, time for BIS < 60 from the end of propofol infusion, intubation conditions, haemodyn
3. Supraglottic Jet Oxygenation and Ventilation in Fiberoptic Intubation Training for Anesthesia Residents in a Simulated Difficult Airway: A Randomized Controlled Study.
Twenty anesthesia residents were randomized to SJOV versus facemask ventilation during 500 fiberoptic intubations in patients with a cervical collar. SJOV achieved zero hypoxemia (0% vs 10%; P<0.001), reduced median cases to competency (11 vs 18 by CUSUM), and improved DOPS scores (P=0.01), with similar Mini-CEX scores. Confidence, engagement, and satisfaction were higher with SJOV.
Impact: Demonstrates a practical airway oxygenation strategy that eliminates hypoxemia during training on real patients and accelerates skill acquisition in fiberoptic intubation.
Clinical Implications: Incorporating SJOV into fiberoptic intubation training curricula may improve patient safety (reduced hypoxemia) and shorten learning curves for trainees in difficult airway scenarios.
Key Findings
- Competency achieved after a median of 11 cases with SJOV versus 18 with facemask ventilation (by CUSUM).
- Hypoxemia (SpO2 <90%) occurred in 0% with SJOV vs 10% with facemask ventilation (P<0.001).
- DOPS scores improved with SJOV (P=0.01) while Mini-CEX scores were similar (P=0.64); trainees reported higher confidence, engagement, and satisfaction with SJOV.
Methodological Strengths
- Prospective randomized design with substantial procedure count (500 intubations)
- Objective competency analysis using CUSUM and standardized assessment tools (DOPS, Mini-CEX)
Limitations
- Small number of trainees with potential clustering effects; details of statistical adjustment not specified
- Single-institution training environment; lack of sham SJOV and limited generalizability
Future Directions: Cluster-randomized, multicenter trials assessing SJOV in diverse airway scenarios, cost-effectiveness, and long-term skill retention and patient outcomes.
BACKGROUND Simulation-based training is essential for anesthesia residents to learn fiberoptic intubation safely. This study evaluated the effect of Supraglottic jet oxygenation and ventilation (SJOV) on skill acquisition, hypoxemia, and trainee performance during simulated difficult airway training. MATERIAL AND METHODS This prospective randomized study included 20 third-year anesthesia residents without prior fiberoptic intubation experience. Each performed 25 fiberoptic intubations (total=500) on patients wearing a cervical collar to
