OBJECTIVES: This study aimed to compare the risk factors and outcomes for organ dysfunction between sepsis-related Pediatric acute respiratory distress syndrome (PARDS) and nonsepsis PARDS. METHODS: We prospective cohort recruited intubated patients with PARDS at four tertiary care centers in Thailand. The baseline characteristics, mechanical ventilation, fluid balance, and clinical outcomes were collected. The primary outcome was organ dysfunction. RESULTS: One hundred and thirty-two mechanically ventilated children with PARDS were included in the study. The median age was 29 months and 53.8% were male. The mortality rate was 22.7% and organ dysfunction was 45.4%. There were 26 (19.7%) and 106 (80.3%) patients who were classified into sepsis-related PARDS and nonsepsis PARDS, respectively. Sepsis-related PARDS patients had a significantly higher incidence of acute kidney injury (30.8% vs. 13.2%, P = 0.041), septic shock (88.5% vs. 32.1%, P < 0.001), organ dysfunction (84.6% vs. 35.8%, P < 0.001), and death (42.3% vs. 17.9%, P = 0.016) than nonsepsis PARDS group. Multivariate analysis adjusted for clinical variables showed that sepsis-related PARDS and percentage of fluid overload were significantly associated with organ dysfunction (odds ratio [OR] 11.414; 95% confidence interval [CI] 1.40892.557, P = 0.023 and OR 1.169; 95% CI 1.0121.352, P = 0.034). CONCLUSIONS: Sepsis-related PARDS patients had more severe illness, organ dysfunction, and mortality than nonsepsis PARDS patients. The higher percentage of fluid overload and presentation of sepsis was the independent risk factor of organ dysfunction in PARDS patients.

OBJECTIVES: This study aimed to develop and prospectively validate a pragmatic two-stage bedside algorithm, integrating an age-adjusted modified Pediatric Early Warning Score (mPEWS) with the American Academy of Pediatrics (AAP) trigger tool for early recognition of sepsis and septic shock. METHODS: This prospective study enrolled children admitted to a hospital from August 2020 to January 2022; all admissions aged 1 month–18 years were monitored. Stage-1 alerted when age-adjusted mPEWS is more than 3, plus abnormal temperature or leukocytosis/leukopenia with band form. Stage-2 applied the trigger tool by physicians; dual positivity in both stages defined a positive screening test. Diagnostic test performance was compared and calculated with Sepsis-2 (sepsis), Sepsis-3 (septic shock), Phoenix septic shock definitions, and 30-day mortality. RESULTS: Among 3202 admissions (1765 patients; median age: 81 months; 54% male), 172 episodes (5.4%) met both stages of the new screening. Compared to the Sepsis-2 criteria, the tool achieved 60.4% sensitivity, 99.1% specificity, 84.3% positive predictive value (PPV), 96.9% negative predictive value (NPV), and area under the curve (AUC) of 0.80. For the Phoenix septic shock definition, sensitivity increased to 100% with 96.2% specificity, 30.2% PPV, 100% NPV, and AUC 0.98. Predicting 30-day mortality yielded 65.0% sensitivity, 95.1% specificity, 13.1% PPV, 99.6% NPV, and AUC 0.80. Screen-positive patients experienced markedly higher in-hospital (24.2% vs. 0.9%) and 30-day (13.1% vs. 0.4%) mortality than those screening negative ( P < 0.001). CONCLUSION: The combined mPEWS/APP trigger tool delivers rapid, simple with entirely clinical stratification, and excellent sensitivity for septic shock with high NPV for sepsis and early mortality. Its simplicity and minimal resource requirements make it a practical solution for improving timely sepsis recognition in resource-constrained pediatric settings.

Sepsis-associated acute kidney injury (SA-AKI) is a common and serious complication in critically ill children and is associated with increased mortality a

Background: Extubation failure increases morbidity and mortality. Non-invasive ventilation (NIV), including high-flow nasal cannula (HFNC), can reduce reintubation rates. Current practice often involves prophylactic use of NIV post-extubation. Electrical Impedance Tomography (EIT) provides real-time monitoring of pulmonary distribution and ventilation. Recent adult studies suggest that EIT has potential in extubation failure prediction, but evidence in children is limited. Our objectives were to evaluate peri-extubation regional lung volume/distribution and to explore EIT-derived physiological changes and on post-extubation respiratory support patterns in critically ill children. Methods: A prospective observational study included intubated patients aged 1 month to 18 years in the PICU who were intubated for over 24 h. Vital signs and chest EIT were recorded pre-extubation (H0), immediately post-extubation (H1), at 30 min (H2), and at 4 h (H3). Patients were categorized by chest X-ray findings into abnormal or normal groups. Results: Among 209 ventilated patients, 54 were included. End-expiratory lung impedance (∆EELI), tidal impedance (TID), and the global inhomogeneity index (GI) demonstrated significant changes across predefined peri-extubation time points. Thirty-eight (70.4%) patients received HFNC or NIV immediately after extubation. No extubation failures occurred, precluding evaluation of extubation failure predictors. In the subgroup analyzed based on chest X-ray findings, differences in TID and ODCL were observed between patients with normal and abnormal chest X-rays immediately after extubation. Conclusions: The ∆EELI, TID, and GI demonstrated significant changes across predefined peri-extubation time points. In the absence of extubation failure events, the ability of EIT monitoring to evaluate extubation failure could not be assessed. The frequent use of prophylactic NIV support after extubation may have influenced post-extubation physiology.
