The purpose of this study is to compare single shot versus sequential bolus spinal technique via a catheter in patients undergoing Cesarean Section. We aim to determine which technique results in less blood pressure reduction and subsequent vasopressor use. Other study endpoints include the incidence of maternal post dural puncture headaches and nausea and vomiting. In addition blood and CSF will be collected to see if biochemical mediators are related to wound hyperalgesia and healing.
