Spinal anaesthesia is the anaesthetic technique of choice for elective caesarean delivery. Hypotension, a result of the decrease in systemic vascular resistance caused by spinal anaesthesia, is a frequent complication occurring in up to 80%. This study is to investigate fluid loading plus vasopressors to vasopressors alone to maintain stable maternal haemodynamics in elective caesarean delivery. The effect of the two methods (continuous prophylactic phenylephrine infusion with and without crystalloid co-loading) on maternal haemodynamics will be compared using the Starling SV Monitor. The Starling SV device is a non invasive cardiac output monitor (NICOM) which is certified and validated for the use in pregnancy.

| Primary | Change in maternal cardiac output (CO) | CO measured by area under the curve (AUC) (L/min.) | measured every minute after induction of spinal anaesthesia (=baseline) until 5 minutes after cord clamping | |
| Secondary | Change in maternal heart rate | Change in maternal heart rate | measured every minute after induction of spinal anaesthesia (=baseline) until 5 minutes after cord clamping | |
| Secondary | Change in maternal diastolic and systolic blood pressure | Change in maternal diastolic and systolic blood pressure (mmHg) | measured every minute after induction of spinal anaesthesia (=baseline) until 5 minutes after cord clamping | |
| Secondary | incidence of maternal nausea | incidence of maternal Nausea (number) | measured every minute after induction of spinal anaesthesia (=baseline) until 5 minutes after cord clamping | |
| Secondary | Change in Apgar scores | The Apgar score is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. The five criteria are summarized using words chosen to form a backronym (Appearance, Pulse, Grimace, Activity, Respiration). | at 1 and 5 minutes after delivery | |
| Secondary | Change in umbilical cord pH | Change in umbilical cord pH | at 1 and 5 minutes after delivery |
