Prospective trial including full term parturients scheduled for a cesarean section under spinal anesthesia. patients are being randomly assigned into 2 groups:
LE group: will be positioned in 15° left tilt with leg elevation with a 30cm height pillow under the heels, this position will be hold after spinal anesthesia until fetal extraction.
Control group: will be positioned in supine with 15° left tilt. the 2 groups will receive a 10ml/kg of crystalloid co-load intravenously, and the spinal anesthesia will be performed in sitting position with the same dose of Bupivacain, morphine and sufentanil.
