Cardiac dimensions during extracorporeal membrane oxygenation.

Unlabelled: Our aim was to analyze left ventricular fractional shortening during extracorporeal membrane oxygenation under the influence of changing volume loading conditions induced by a ductal left-to-right shunt. In all patients, the fractional shortening was observed using echocardiography before, during, and after bypass, irrespective of the presence or absence of the ductal left-to-right shunt. During membrane oxygenation, there was a significant decrease in fractional shortening (p less than 0.

Measurement of the ductal L-R shunt during extracorporeal membrane oxygenation in the lamb.

Objective: In neonates, initially a ductal shunt is often observed during veno-arterial extracorporeal membrane oxygenation (ECMO). Depending on the degree of pulmonary hypertension in these patients, the ductal shunt will be right to left (R-L), left to right (L-R), or bidirectional. A ductal L-R shunt will possibly lead to pulmonary hyperperfusion and interact with ECMO weaning.

Hemodynamic changes during opening of the bridge in venoarterial extracorporeal membrane oxygenation.

OBJECTIVE: To investigate the cause of the hemodynamic changes occurring during opening of the bridge in venoarterial (VA) extracorporeal membrane oxygenation (ECMO). DESIGN: Prospective intervention study in animals. SETTING: Animal research laboratory of a university medical center.

The influence of ductal left-to-right shunting during extracorporeal membrane oxygenation.

Background/purpose: The aim of this study was to analyze whether a ductal left-to-right (L-R) shunt will prolong extracorporeal membrane oxygenation (ECMO) in neonates with severe pulmonary hypertension. This report discusses the onset and termination of a ductal L-R shunt and its potential influences on ECMO when pulmonary hypertension decreases during venoarterial bypass.

Methods: Twenty-nine neonates were monitored during veno-arterial ECMO, using bedside echocardiography with 12-hour interval observations.

Excellent long-term outcome for survivors of apple peel atresia.

Background: Apple peel atresia is the rarest type of small bowel atresia. Because of its rare occurrence and high mortality rate, little is known about the long-term outcome of these children.

Methods: The patient charts, operative reports, and office notes of 15 children with apple peel atresia from 6 pediatric surgical centers in the Netherlands were reviewed.
