ABSTRACT
BACKGROUND:
Near-infrared spectroscopy (NIRS) has been shown to provide reliable noninvasive monitoring of regional oxygenation in a variety of clinical settings. We set out to test its feasibility as a monitor of fetal and placental oxygenation during fetal cardiac surgery. MATERIALS ANDMETHODS:
Six ovine fetuses from 98-110 ds gestation were placed on fetal bypass for 30 min and followed post-bypass for 2 h. A NIRS probe (MI INVOS 5100B; Somanetics, Troy, MI) was placed on the pregnant uterine horn during and after fetal surgery. NIRS values were compared with blood gas values obtained by direct sampling from umbilical circulation.RESULTS:
NIRS values positively correlated with umbilical venous oxygen saturation (R(2)=0.891, P<0.01) and partial oxygen pressure values (R(2)=0.810, P<0.01). NIRS values also correlated to a lesser extent with umbilical venous pH and pCO(2), and fetal arterial pH, pO(2), and oxygen saturation.CONCLUSIONS:
This is the first report of application of NIRS in the setting of fetal surgery. NIRS permits noninvasive assessment of placental oxygen saturation and pO(2). This technology is a simple and useful tool for real-time monitoring of oxygen delivery to the fetus during maternal-fetal cardiac interventions and of overall well-being of the fetal-placental unit.
