Usefulness of central venous oxygen saturation monitoring during bidirectional Glenn shunt.
A PediaSat™ oximetry catheter (PediaSat: Edwards Lifesciences Co., Ltd., Irvine, CA, U. S. A.), which facilitates continuous measurement of central venous oxygen saturation (ScvO2), may be useful for surgery for pediatric congenital heart disease. ⋯ Blockage of the right pulmonary artery and right superior vena cava decreased the oxygen saturation, ScvO2, and rSO2, but increased the central venous pressure. Although changes in ScvO2 were parallel to those in rSO2, the former showed more marked changes. A combination of ScvO2 and rSO2 for monitoring during Glenn shunt may be safer.
