    Extracorporeal membrane oxygenation in pediatric septic shock: A single-center experience in Chile
    (SAGE Publications, 2026-01) Godoy, Loreto; Yunge, Mauricio; Rufs, Jorge; Gatica, Alejandra; Muñoz, Carlos; Valverde, Cristian
    Background: Refractory septic shock (RSS) in children carries high mortality despite advances in critical care. Extracorporeal membrane oxygenation (ECMO) is a rescue therapy when conventional management fails. Evidence from Latin America remains limited, with no detailed reports from Chile. Methods: We conducted a retrospective single-center study (2009–2024) in a Chilean Pediatric ICU. Patients aged 1 month to 17 years with septic shock unresponsive to maximal conventional therapy were included. We analyzed demographics, illness severity, ECMO modality, complications, and outcomes. Primary endpoint was survival to hospital discharge. Results: Nine patients received ECMO (median age=6.3 years). All had RSS, frequently associated with severe ARDS. Configurations included venoarterial (VA; n=4), venovenous (VV; n=4), and venoarteriovenous (VAV; n=1), all via peripheral cannulation. Pre-ECMO median vasoactive-inotropic score was 117, and 78% required renal replacement therapy during ECMO. Overall survival was 55% (5/9). Survivors had longer ECMO runs (median 11 days vs 3 days) and ICU stays (median 63 days vs 5 days). Hemorrhage was the most frequent complication (intracranial n=3; gastrointestinal n=1). One survivor developed hemiparesis; no cognitive impairment was observed at 1-year follow-up. Conclusions: ECMO can be an effective rescue therapy for pediatric RSS, even without central cannulation capability. Distinguishing cardiogenic from vasoplegic phenotypes and identifying severe ARDS guided configuration selection (VA vs VV). These findings highlight the feasibility of peripheral ECMO in carefully selected patients within resource-limited settings, achieving survival comparable to international reports.

    Latin American Consensus on the Management of Sepsis in Children: Sociedad Latinoamericana de Cuidados Intensivos Pediátricos [Latin American Pediatric Intensive Care Society] (SLACIP) Task Force: Executive Summary
    (SAGE Publications, 2022) Fernández-Sarmiento, Jaime; De Souza, Daniela Carla; Martinez, Anacaona; Nieto, Victor; López-Herce, Jesús; Soares Lanziotti, Vanessa; Arias López, María del Pilar; Brunow De Carvalho, Werther; Oliveira, Claudio F.; Jaramillo-Bustamante, Juan Camilo; Díaz, Franco; Yock-Corrales, Adriana; Ruvinsky, Silvina; Munaico, Manuel; Pavlicich, Viviana; Iramain, Ricardo; Márquez, Marta Patricia; González, Gustavo; Yunge, Mauricio; Tonial, Cristian; Cruces, Pablo; Palacio, Gladys; Grela, Carolina; Slöcker- Barrio, Maria; Campos-Miño, Santiago; González- Dambrauskas, Sebastian; Sánchez-Pinto, Nelson L.; Celiny García, Pedro; Jabornisky, Roberto
    Objective: The aim of this study was to develop evidence-based recommendations for the diagnosis and treatment of sepsis in children in low- and middle-income countries (LMICs), more specifically in Latin America. Design: A panel was formed consisting of 27 experts with experience in the treatment of pediatric sepsis and two methodologists working in Latin American countries. The experts were organized into 10 nominal groups, each coordinated by a member. Methods: A formal consensus was formed based on the modified Delphi method, combining the opinions of nominal groups of experts with the interpretation of available scientific evidence, in a systematic process of consolidating a body of recommendations. The systematic search was performed by a specialized librarian and included specific algorithms for the Cochrane Specialized Register, PubMed, Lilacs, and Scopus, as well as for OpenGrey databases for grey literature. The GRADEpro GDT guide was used to classify each of the selected articles. Special emphasis was placed on search engines that included original research conducted in LMICs. Studies in English, Spanish, and Portuguese were covered. Through virtual meetings held between February 2020 and February 2021, the entire group of experts reviewed the recommendations and suggestions. Result: At the end of the 12 months of work, the consensus provided 62 recommendations for the diagnosis and treatment of pediatric sepsis in LMICs. Overall, 60 were strong recommendations, although 56 of these had a low level of evidence. Conclusions: These are the first consensus recommendations for the diagnosis and management of pediatric sepsis focused on LMICs, more specifically in Latin American countries. The consensus shows that, in these regions, where the burden of pediatric sepsis is greater than in high-income countries, there is little high-level evidence. Despite the limitations, this consensus is an important step forward for the diagnosis and treatment of pediatric sepsis in Latin America.
