Abstract
Background
Venovenous extracorporeal membrane oxygenation (VV-ECMO) is often used for lung rest in critically ill patients, including pregnant patients.
Objectives
We aimed to determine how pregnant and non-pregnant patients requiring VV-ECMO differed from each other and how pregnancy impacted in-hospital mortality.
Methods
We used the National Inpatient Sample to identify a cohort of female patients requiring VV-ECMO from 2016 to 2021, stratified by pregnancy status. Baseline characteristics were compared using Pearson chi-square test. Predictors of in-hospital mortality, including pregnancy and complications from VV-ECMO, were determined using multivariate analysis with a logistic regression model.
Results
Of 7365 female patients requiring VV-ECMO, 700 (9.5 %) were pregnant. Pregnant patients were younger. COVID-19 was more prevalent in pregnant patients (72.9 % versus 36.4 %, p < 0.001). Infectious complications were more common in non-pregnant patients (64.1 % versus 43.6 %, p < 0.001). Pregnant patients suffered from less in-hospital mortality (20.0 % versus 38.5 %, p < 0.001), and pregnancy predicted survival (adjusted odds ratio (OR): 0.49 [0.27–0.89], p = 0.02). Length of stay ≥7 days and COPD were associated with reduced odds of in-hospital mortality; chronic heart failure, COVID-19, and VV-ECMO complications were associated with increased odds of in-hospital mortality.
Conclusions
These findings underscore the unique clinical profile and outcomes of pregnant females requiring VV-ECMO, highlighting the need for tailored management strategies. Prospective studies are essential to validate these observations and optimize care for this vulnerable patient population.
期刊介绍:
Heart & Lung: The Journal of Cardiopulmonary and Acute Care, the official publication of The American Association of Heart Failure Nurses, presents original, peer-reviewed articles on techniques, advances, investigations, and observations related to the care of patients with acute and critical illness and patients with chronic cardiac or pulmonary disorders.
The Journal''s acute care articles focus on the care of hospitalized patients, including those in the critical and acute care settings. Because most patients who are hospitalized in acute and critical care settings have chronic conditions, we are also interested in the chronically critically ill, the care of patients with chronic cardiopulmonary disorders, their rehabilitation, and disease prevention. The Journal''s heart failure articles focus on all aspects of the care of patients with this condition. Manuscripts that are relevant to populations across the human lifespan are welcome.
