Abstract
Objective: To investigate the value of echocardiography in monitoring hemodynamics of postcardiotomy cardiac shock (PCS)
patients before, during, and after weaning from extracorporeal membrane oxygenation (ECMO). Methods: Fifty-two patients
were divided into a successful weaning group (Group A, n=23) and non-successful group (Group B, n=29). Hemodynamic
parameters measured by echocardiography were collected before, during, and after ECMO. The intra-group changes and inter-
group differences were analyzed. Results: In group A, the central venous pressure (CVP), proximal right ventricular outflow
tract (RVOT), tricuspid annular plane systolic excursion (TAPSE), velocity of tricuspid valve (TVDV), and systolic velocity
of tricuspid annulus (s‘TV) during EMCO were significantly lower than before ECMO. After ECMO, left ventricular ejection
fraction (LVEF), systolic velocity of mitral annulus (s‘MV), and velocity-time integral of LV outflow tract (LVOT-VTI) were
higher than pre-ECMO, and CVP, LVEF, s‘MV, LVOT-VTI, RVOT, TAPSE, TVDV and s‘TV were higher than during ECMO
(all p<0.05). In group B, compared to pre-ECMO, subjects exhibited decreased CVP, RVOT, TAPSE, TVDV and s‘TV during
ECMO. TAPSE, TVDV, and s‘TV were continuously lower after ECMO, while CVP and RVOT became higher after ECMO
(all p<0.05). After ECMO, LVEF, s‘MV, LVOT-VTI, TAPSE, TVDV and s‘TV in group A were higher than those in group
B (all p<0.05). Multiple logistic regression analysis showed that LVEF (OR=1.387, 95%CI: 1.072-1.793, p=0.013) and Tei
index (OR=-0.005, 95% CI: 0.000-0.939, p=0.047) were independent factors related to the successfulness of ECMO weaning.
Conclusions: Quantitative assessment of both LV and RV by echocardiography is important for ECMO weaning.
