VV ECMO respiratory failure support offers a critical lifeline for patients who do not respond to traditional mechanical ventilation. Recently, researchers at the National Institute of Cardiology Ignacio Chávez (INCICh) shared five years of clinical data regarding their cardiovascular intensive care unit. Their findings reveal a promising 70% in-hospital survival rate among patients with severe respiratory distress. This result exceeds many previously reported international benchmarks for similar critical care settings. Primarily, the medical team utilized venovenous extracorporeal membrane oxygenation (VV-ECMO) for SARS-CoV-2 related failures.
Interestingly, comorbidities and anthropometric variables showed no significant association with mortality rates in this specific cohort. However, non-survivors typically experienced longer stays in the intensive care unit and required extended mechanical ventilation. Furthermore, acute kidney injury appeared as the most frequent complication during the support period. Despite its high frequency, renal failure did not directly correlate with an increased risk of death. Therefore, specialized protocols and dedicated multidisciplinary teams play a vital role in managing these complex cases. Consequently, clinical centers must establish rigorous selection criteria to ensure the best possible outcomes for their patients.
While international registries often report survival rates between 50% and 60%, specialized centers with established protocols have achieved rates as high as 70% in recent years.
Acute kidney injury is frequently cited as the most common complication. Other risks include bleeding at the cannulation site, infection, and thrombosis, which require constant monitoring by the ICU team.
