简要总结
This study is being conducted to study light scattering properties of maternal-fetal tissue.
详细描述
The ISS customized commercial frequency domain oximeter is used to obtain light scattering information from the maternal abdomen for 10-20 minutes preoperatively and postoperatively in subjects who are having a scheduled C-section.
