Summary

Hypotension after spinal anesthesia for cesarean section is one of the most common perioperative issue, with an incidence up to 83%.Hypotension is mainly induced by the associated sympathetic blockade, with a drop of peripheral vascular resistance in the lower extremities and an increase in venous capacitance. Hypotension is a distress for both anesthesiologists and obstetricians as it endangers parturient's hemodynamics and compromises the uteroplacental blood flow. In clinical practice, there are several ways to treat hypotension after spinal anesthesia such as preloading with intravenous fluids and administrating ephedrine. Normotensive maternal blood pressure does neither guarantee the well-being of the fetus nor ensure the tissue perfusion of the parturient. Based on the anatomy and physiology basis, we hypothesize that uterine perfusion under spinal anesthesia would correlate with the perfusion of the lower extremities. To measure the perfusion of the lower extremities, we use a relative new tool, the non-invasive transcutaneous near infrared spectroscopy.
