Introduction:
The aim of this study was to summarize the infection situation of patients during extracorporeal membrane oxygenation (ECMO) treatment, and analyze the relevant infectious indexes before and after ECMO treatment; so as to provide clinical evidence for the control of infection after ECMO treatment.
Methodology:
A retrospective analysis was conducted from May 2014 to January 2024 on 66 patients treated with ECMO at the Department of Intensive Care Medicine, Daping Hospital, Army Medical University. The patients' general clinical data were collected, focusing on infection types, pathogenic bacteria, anti-infective regimens, infection markers, and coagulation function. Additionally, risk factors for infection in intensive care unit (ICU) patients undergoing ECMO treatment were analyzed.
Results:
Pulmonary infections were the most common among the patients in this study, and Gram-negative bacilli were the predominant pathogens. Significant reductions were observed in white blood cell count (p < 0.05, n = 57), platelet count (p < 0.05, n = 56), and fibrinogen levels (p < 0.05, n = 57) 48 hours after ECMO treatment. Of the 66 ECMO patients, 30 survived. The length of stay in the ICU was identified as an independent risk factor for adverse events following ECMO treatment.
Conclusions:
Controlling infection during ECMO is the cornerstone of survival and prognosis of patients. Mechanical ventilation time, continuous renal replacement therapy, central venous catheterization time, and antibiotic treatment time may be related to infection after ECMO. Early bacterial culture; and prophylactic, empirical, and targeted antimicrobials contribute to infection control.
Insights
Controlling infections during extracorporeal membrane oxygenation (ECMO) is crucial for patient survival. This study analyzed ECMO patient infections, finding pulmonary infections and Gram-negative bacteria common, and identified ICU length of stay as a risk factor.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Cardiopulmonary Support
Background:
- Extracorporeal membrane oxygenation (ECMO) is a life-support measure for critically ill patients.
- Infections pose a significant threat to patients undergoing ECMO treatment.
- Understanding infection patterns and risk factors is vital for improving outcomes.
Purpose of the Study:
- To summarize the infection status of patients during ECMO.
- To analyze changes in infectious indexes before and after ECMO.
- To provide evidence for infection control strategies in ECMO patients.
Main Methods:
- Retrospective analysis of 66 patients treated with ECMO.
- Data collection included infection types, pathogens, treatments, infection markers, and coagulation.
- Analysis of risk factors for infection in ICU patients on ECMO.
Main Results:
- Pulmonary infections were most frequent, with Gram-negative bacilli as primary pathogens.
- Significant decreases in white blood cell count, platelet count, and fibrinogen observed post-ECMO.
- Intensive care unit (ICU) length of stay was an independent risk factor for adverse events.
Conclusions:
- Infection control is paramount for ECMO patient survival and prognosis.
- Factors like ventilation duration, RRT, catheterization, and antibiotic duration may influence post-ECMO infection.
- Early bacterial cultures and appropriate antimicrobial strategies are key to managing infections.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
