Supine hypotensive syndrome often occurs following spinal anesthesia for cesarean delivery.In our study we base the regulation and drug administration both on the regular monitor and on a novel monitor which reflects upon the hemodynamic changes. Our aim is to observe whether the outcome of SHS patients with anesthesia management based on hemodynamic figures differs from those based on experience.
