Official Title: Neonatal Acid-base Status After Elective Cesarean Delivery Under Spinal Anesthesia - a Comparison of Maternal Supine Horizontal Position Versus Left Lateral Table Tilt

Brief Summary: This study aims to compare the neonatal acid-base status of women who remain supine horizontal, with women who are tilted to the left side by 15° during elective cesarean delivery at term under spinal anesthesia, with systolic BP maintained at baseline with a phenylephrine (PE) infusion. The null hypothesis is that the position of the patient (supine horizontal or tilted) during cesarean section will make no difference to neonatal wellbeing. The primary outcome will be the neonatal umbilical arterial base deficit (BD) at birth. The investigators will also examine the effects of maternal position during cesarean section under spinal anesthesia on maternal cardiac output (CO) and whether these changes have a correlation with the neonatal umbilical cord blood acid-base status. The secondary outcome will be the total phenylephrine dose requirement at 15 minutes after spinal injection.
