Research Themes

- Time-to-ECMO initiation and systems of care
- Neonatal respiratory support safety and iatrogenic complications
Selected Articles
1. [ECMO therapies in a low-volume, peripheral hospital].
In a 10-year, single-center retrospective analysis at a peripheral regional hospital, 54 ECMO cases (53 VV, 1 VA) were initiated, with 48% ICU survival among non-transferred patients. The study suggests decentralized ECMO can be safe and effective when supported by a collaborating specialized center, potentially reducing delays to cannulation.
Impact: This study provides real-world outcome data indicating that peripheral hospitals can safely implement ECMO with specialist support, informing system design for time-sensitive respiratory failure care.
Clinical Implications: Supports hub-and-spoke ECMO models, on-site cannulation to minimize delays, structured collaboration/tele-ECMO, and standardized training/protocols at peripheral hospitals.
Key Findings
- Over 2013–2023, 54 ECMO runs were performed (53 venovenous, 1 venoarterial) at a peripheral hospital.
- Four patients were transferred after ECMO initiation; among the remaining 50, 24 survived ICU care (48% survival).
- Findings suggest safe, effective ECMO delivery in peripheral hospitals when supported by a specialized center, limiting transfers to complicated courses.
Methodological Strengths
- Consecutive, 10-year single-center dataset capturing all ECMO cases
- Clear reporting of modality (VV/VA), transfers, and ICU survival
Limitations
- Retrospective, single-center design with small sample size
- No risk adjustment or comparator group to benchmark outcomes
Future Directions: Develop multicenter registries to benchmark decentralized ECMO, evaluate time-to-ECMO metrics, and test standardized training/tele-ECMO protocols in prospective designs.
2. Iatrogenic pneumothorax in a term neonate.
A term neonate developed respiratory distress shortly after birth and later was identified to have iatrogenic pneumothorax during early oxygen therapy via nasal cannula. The report emphasizes the need for cautious respiratory support settings and close monitoring to prevent barotrauma.
Impact: Educational value in recognizing iatrogenic pneumothorax risk during routine neonatal respiratory support and reinforcing safe oxygen/flow titration.
Clinical Implications: Encourages careful titration of oxygen and flow in neonates, early recognition of pneumothorax signs (cyanosis, distress, grunting), and readiness for prompt intervention pathways.
Key Findings
- Term neonate with normal birth parameters developed early respiratory distress with cyanosis and grunting.
- Iatrogenic pneumothorax occurred during early oxygen therapy via nasal cannula (6 L, 25% FiO2).
- Highlights need for cautious respiratory support settings and vigilant monitoring to avoid barotrauma.
Methodological Strengths
- Clear presentation of early clinical signs and initial oxygen therapy parameters
- Practical, bedside-focused learning points for neonatal teams
Limitations
- Single case with limited generalizability
- Abstract provides limited procedural detail and outcomes
Future Directions: Define safe oxygen/flow thresholds and monitoring protocols for neonatal respiratory support; develop checklists to minimize iatrogenic barotrauma.
