Publication Characteristics of Medically Transported Critically Ill Children with Respiratory Failure in Latin America: Implications for Outcomes(2021) Serra, Jesus; Díaz, Franco; Cruces, Pablo; Carvajal, Cristobal; Nuñez, Maria; Donoso, A.; Bravo, J A; Carbonell, M.; Courtie, C.; Fernández. A.; Martínez, L.; Martínez, J.; Menta, S.; Pedrozo, Luis; Wegner, A.; Monteverde, Nicolas; Jaramillo, Juan; Jabornisky, Roberto; González, Sebastián; Kudchadkar, Sapna; Vásquez, Pablo; On behalf of LARed NetworkSeveral challenges exist for referral and transport of critically ill children in resource-limited regions such as Latin America; however, little is known about factors associated with clinical outcomes. Thus, we aimed to describe the characteristics of critically ill children in Latin America transferred to pediatric intensive care units for acute respiratory failure to identify risk factors for mortality. We analyzed data from 2,692 patients admitted to 28 centers in the Pediatric Collaborative Network of Latin America Acute Respiratory Failure Registry. Among patients referred from another facility (773, 28%), nonurban transports were independently associated with mortality (adjusted odds ratio = 9.4; 95% confidence interval: 2.4-36.3).Publication Risk factors and outcomes of pediatric non-invasive respiratory support failure in Latin America(2024) Escobar, Diana; Barajasz, Juan; Peralta, Juan; Jaramillo, Juan; Monteverde, Nicolas; Serra, Jesus; Caporal, Paula; Menta, Soledad; Lasso, Ruben; Zemanate, Eliana; Martínez, Javier; Herrera, Hernan; Martínez, Luis; Castro, Francisca; Carvajal, Cristobal; Decía, Monica; Jabornisky, Roberto; Diaz, Franco; Gonzalez, Sebastian; Vasquez, Pablo; On behalf of LARed NetworkBackground: Noninvasive respiratory support (NRS) is standard in pediatric intensive care units (PICUs) for respiratory diseases, but its failure can lead to complications requiring invasive mechanical ventilation (IMV). This study aimed to identify risk factors for NRS failure in children with acute respiratory failure (ARF) in PICUs, and compare complications and outcomes between IMV-only and NRS failure patients. Methods: We conducted a cohort study using data from the LARed Network prospective registry (April 2017-November 2022), in children under 18 years admitted to PICUs for ARF. Cases were divided into subgroups: those managed with IMV only, those who experienced NRS failure requiring IMV, those who received NRS successfully, and those who did not require NRS or IMV. Exclusions included patients with home respiratory support prior to admission, patients without PICU discharge at the cutoff date of the analysis and those with incomplete data. Multivariate mixed models analyzed NRS failure risk factors, and complications between the IMV-only and NRS failure groups, using centers as a random effect. Results: A total of 7374 children met the inclusion criteria, with 6208 in the NRS group and 1166 in the IMV-only group. The NRS success rate was 85.3 %. Risk factors for NRS failure included age (median of 4.6 months, interquartile range of 2.1-14.2 months), history of prematurity (adjusted odds ratio [aOR]=1.53, 95 % confidence interval [CI]: 1.20 to 1.95) or malnutrition (aOR=1.85, 95 % CI: 1.18 to 2.91), suspected bacterial infection (aOR=5.12, 95 % CI: 4.05to 6.49), FiO2 >30 % (aOR=1.52, 95 % CI: 1.18 to 1.97), severe hypoxemia with SpO2/FiO2 ≤150 (aOR=1.85, 95 % CI: 1.48 to 2.30), tachypnea (aOR=1.42, 95 % CI: 1.18 to 1.72), tachycardia (aOR=1.77, 95 % CI: 1.47 to 2.12), and lung consolidations (aOR=1.45, 95 % CI: 1.14 to 1.85) or interstitial infiltrates (aOR=1.29, 95 % CI: 1.05 to 1.58) on chest X-ray. There were no significant differences in morbidity, mortality, duration of IMV, or PICU length of stay between patients who received IMV only and those who experienced NRS failure. However, patients who experienced NRS failure were more likely to develop withdrawal symptoms related to sedative or opioid discontinuation and/or delirium (aOR=2.57, 95 % CI: 1.85 to 2.57). Conclusion: This study identified key risk factors for predicting NRS failure in children with acute ARF in PICUs, including younger age, prematurity, malnutrition, suspected bacterial infection, FiO2 >30 %, severe hypoxemia (SpO2/FiO2 ≤150), tachypnea, tachycardia, and radiological findings such as lung consolidation and interstitial infiltrates. Compared to patients managed with IMV from the start, those who experienced NRS failure were more likely to develop withdrawal symptoms and/or delirium, although clinical outcomes such as mortality, IMV duration, and PICU length of stay were similar in both groups.
