The hypothesis of this study is as follows: In parturients undergoing Cesarean section under spinal anesthesia, co-loading of 1 liter of crystalloids, with placing the spinal, along with administering a phenylephrine infusion and glycopyrrolate, enables placing a spinal with minimal perioperative nausea and vomiting and good intra and post-operative pain relief.~The study group will receive phenylephrine infusion [dilution 100micrograms /cc] Rate of infusion 50micrograms /hour, approximately 30ml/hour To be started immediately after the placement of the spinal anesthetic Patient will also be given .4mg [1cc of glycopyrrolate], with the starting of the infusion~The control group, will receive phenylephrine infusion [dilution 100micrograms /cc] Rate of infusion 50micrograms /hour, approximately 30ml/hour To be started immediately after the placement of the spinal anesthetic Patient will also be given a placebo [1cc of N saline], with the starting of the infusion~Following the administration of the study drug/placebo, the patient will be monitored for severity of nausea , vomiting and pain at 5 minutes intervals from placement of the spinal to delivery of the baby, and then at 15 minutes intervals from delivery of the baby till the end of the surgery ( the cesarean section)
