Research progress on the extracorporeal membrane oxygenation intubation-related infection

Abstract

Extracorporeal membrane oxygenation (ECMO) is commonly a transitional treatment way used in patients with severe heart and lung problem. Deoxidized blood is extracted through venous intubation, and then returned to the arterial or venous system after oxygenation. There is a risk of intubation-related infection in arterial or venous intubation. Once the infection occurs, it will prolong the patient's length of hospitalization stay, increase the mortality and medical expenses. Longer duration of ECMO and higher simplified acute physiology score (SAPS) were risk factors for infection. At present, the main diagnostic method for infection is blood culture. Ultrasound-guided percutaneous cannulation can reduce the occurrence of infection; if infection still occurs, antibiotics should be actively treated. In order to bring reference for clinical work, this article reviews the incidence, risk factors, diagnostic criteria, prevention strategies, treatment methods and other key points of ECMO intubation-related infection.
