Comparative StudyCapillary (heelstick) versus venous blood sampling for the determination of glucose concentration in the neonate.
Various sites may be used to obtain blood (plasma) for the determination of the glucose concentration in the neonate. Because multiple sites may be sampled in the same neonate, it is important to determine the variability in blood glucose concentration which may result from such sampling. ⋯ When the capillary (heelstick)-venous glucose concentration difference was compared to the mean of the capillary (heelstick) and venous glucose concentrations, a difference of +/- 0.5 mM (9 mg/dl) was noted in 3 of 25 neonates. Appropriately obtained capillary (heelstick) blood samples provide measurement of blood glucose concentration which are variable compared to venous samples, but which are probably not significant physiologically.

Comparative StudyExtracorporeal membrane oxygenation in lambs through umbilical vessel perfusion: cardiac and hepatic complications.
Twin lambs were delivered by ceasarean section near term, aralyzed, sedated and randomly assigned to either mechanical ventilation or umbilical arteriovenous ECMO for 48 hours. Umbilical arteriovenous ECMO provided adequate gas exchange with minimal or no ventilation of the native lungs. However, at autopsy, animals treated with umbilical ECMO showed right heart dilation and liver necrosis or hemorrhage compared to their twins treated with mechanical ventilation.
