Accuracy of non-invasive measurement of cardiac output using electrical cardiometry in preterm infants during the transitional period: A comparison with transthoracic Doppler echocardiography.

ABSTRACT: This prospective observational study aimed to assess the agreement of cardiac output measurements obtained with transthoracic echocardiography (CO_ECHO) and electrical velocimetry (CO_EV) and the impact of relevant variables on CO_EV accuracy in preterm infants during the transitional period. Simultaneous measurements of CO_EV and CO_ECHO were performed in preterm infants < 32 weeks' gestation and/or < 1500 g during the first 72 h of life. Bland-Altman analysis was performed and bias and mean percentage error (MPE) were calculated. The impact of a hemodynamically significant duct (hsPDA), ongoing cardiovascular drugs and ventilatory support was also assessed using a generalized least squares random-effects model. A total of 170 pairs of CO<
