연구실 소개
장원진 교수의 연구실은 소아 환자의 임상적 위기 조기 발견과 생명 유지 치료 기술의 최적화를 핵심으로 삼고 있습니다. 특히 소아 환자의 생체신호 평가, 조기경고 점수 시스템, 그리고 기계적 통기 및 임상적 합병증 관리에 대한 기반 연구를 진행하고 있으며, 임상 현장에 적용 가능한 실용적 도구 개발에도 주력하고 있습니다. 최근에는 인공지능 기반 모니터링 기술과 ECMO를 활용한 만성 폐질환 치료 등 고도화된 생명연장 치료 전략에 대한 임상적 사례 분석도 함께 진행하고 있습니다.

9In our study group, treatment with a higher dose of TBI during conditioning resulted in better EFS for ALL patients who underwent HSCT in second CR. Further study is needed to determine potential long-term complications associated with a higher TBI dose.
Accurate assessment of pediatric vital signs is critical for detecting abnormalities and guiding medical interventions, but interpretation is challenging due to age-dependent physiological variations. Therefore, this study aimed to develop age-specific centile curves for blood pressure, heart rate, and respiratory rate in pediatric patients and create a user-friendly web-based application for easy access to these data. We conducted a retrospective cross-sectional observational study analyzing 3,
Bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH) are potentially fatal complications in prematurely born infants. Extracorporeal membrane oxygenation (ECMO) may be a life-saving option for managing infants with BPD and PH. We present 2 patients who were successfully weaned off mechanical ventilators (MVs) through the application of ECMO. The patients were transferred to our institution after receiving MV care for 8 and 10 months, respectively, for BPD and PH. We were able to remo
ARS, a single parameter system, had good specificity and negative predictive value for predicting critical events; however, sensitivity and positive predictive value were not good, and medical staff compliance was poor.
Early identification of clinical deterioration in hospitalized children is essential to improve outcomes and prevent critical events. Over the past two decades, structured approaches such as pediatric early warning scores and rapid response systems have provided a framework for systematic risk detection in general wards. More recently, artificial intelligence and continuous monitoring technologies have begun to transform this field, offering the potential for more timely and accurate recognition
Circulating cell-free DNA in the blood of castration-resistant prostate cancer patients harbors tumor-specific genomic information. Here, we investigated common genomic variants and whether these data correlate with treatment response.Minimum 20ng of cfDNA were extracted from plasma of CRPC patients. Hybrid-capture based genomic profiling (Axen Cancer Panel 1, Macrogen) was performed to sequence 88 genes in each samples. The data was presented with mutated gene, DNA change, allele frequency(AF).
Background:Optimal sedation assessment in critically ill children remains challenging due to the subjective nature of behavioral scales and intermittent evaluation schedules. This study aimed to develop a deep learning model based on heart rate variability (HRV) parameters and vital signs to predict effective and safe sedation levels in pediatric patients.Methods: This retrospective cross-sectional study was conducted in a pediatric intensive care unit at a tertiary children’s hospital. We devel

Laundry detergent pod (LDP) exposure has been reported to be fatal in children younger than 2 years, leading to respiratory or central nervous system depression. While gastrointestinal irritation is the most common symptom, there are reported cases of severe acidosis with respiratory depression or pneumonia, resulting in mortality. To our best knowledge, there is no report on a case of LDP exposure presenting with acute respiratory distress syndrome requiring extracorporeal membrane oxygenation
